As is well known, digital isolators can be derived into hundreds of sub-models based on various combinations of product parameters such as the number of channels (2/3/4/6/8 channels), channel orientation (positive/reverse channel count), withstand voltage rating (3.75kV/5kV/5.75kV/8.5kV), CMTI rating (>150kV/us/>200kV/us/>250kV/us), and package specifications. 

However, due to the production scheduling logic of wafer and packaging lines, factory capacity is usually prioritized for large-volume standardized packaging orders, resulting in long lead times and shortages of many models of digital isolators in the market.

This supply and demand situation has also reshaped the selection logic of digital isolators: during the solution design phase, customers not only need to pay attention to the electrical performance indicators of digital isolators, but also need to comprehensively evaluate the supply chain stability and product cycle management capabilities of the original equipment manufacturers.

Especially for industries with continuous production, such as industrial automation, green electricity (wind, solar and energy storage), medical electronics and automotive electronics, if key isolation components cannot be supplied continuously due to delivery schedule fluctuations or production stoppages, it may lead to project delays and increased inventory costs, or even cause adverse consequences such as changes to the overall design, re-verification of certifications or interruption of production plans, resulting in direct economic losses for enterprises.

HOPERF | How to overcome the pressure of delivery time for digital isolators?

In response to the long-standing issues of extended delivery times and shortages of spot goods in the digital isolator industry, HOPERF, as a leading domestic manufacturer of digital isolators, has launched a prefabricated digital isolator supply solution that can quickly respond to customer delivery requirements and effectively solve the delivery time pressure issues of various sub-models.

The pre-fabricated digital isolator supply solution refers to the production of digital isolators without setting or programming the components. Only the core electrical isolation function is retained, and the chips are stored in a nitrogen cabinet in the form of "pre-fabricated chips" to ensure that the quality remains unchanged during long-term storage.

When a customer submits a relevant out-of-stock model, HOPERF can quickly remove the "pre-fabricated chip" from the nitrogen cabinet and call the corresponding programming program to program and configure it as a digital isolator of the corresponding specifications.

Based on the above-mentioned prefabricated digital isolator supply solution, HOPERF can quickly derive different combinations of channel configurations, voltage ratings, and CMTI ratings, narrowing the original hundreds of subdivided models of digital isolators into a few "prefabricated chip" models.

Regardless of the model of digital isolator ordered by the customer, HOPERF can respond quickly to customer needs and efficiently complete the batch delivery of digital isolators, thereby enhancing the resilience of the customer's supply chain.

It is worth mentioning that, in order to ensure the batch reliability of digital isolators, HOPERF will strictly implement sampling verification procedures, including PC, PCT and TCT tests, after completing the device programming and configuration. Only after ensuring that the digital isolators are functional and perform correctly will silkscreen marking and tape packaging be carried out.

Furthermore, in terms of specific timeframes, based on the pre-fabricated digital isolator supply solution , HOPERF can complete the programming and delivery of millions of specific model isolation chips in as little as one week after the customer completes the selection and places the order. This can help customers avoid problems such as production line shutdowns and order delays caused by material shortages, and significantly improve the resilience of the customer's supply chain.

HOPERF | Domestic Digital Isolators: On-time Delivery and Performance Both Online

For HOPERF, developing, producing, and selling a digital isolator chip has never been about simply competing with similar products in terms of performance indicators. Instead, it's about forging a differentiated development path through technological innovation based on a deep understanding of customer needs.

HOPERF rejects ineffective homogeneous competition and refuses to use price wars to reap the company's independent innovation capabilities in a red ocean market.

Currently, HOPERF's CMT812X, CMT804X, and CMT826X series of multi-channel general-purpose digital isolators fully support the use of pre-fabricated digital isolator supply solutions , which can quickly match orders for various sub-specifications , alleviate the problem of inventory backlog and spot shortages of multiple models from the source, and further enhance the supply chain stability of domestic and foreign customers.

In addition to their superior delivery times, the CMT812X, CMT804X, and CMT826X series of multi-channel general-purpose digital isolators also boast excellent product performance. They can flexibly adapt to different topology requirements of 2/4/6 channels and support isolation voltages of up to 3.75Vrms (narrow-body package) / 5kVrms (wide-body package), 8kV surge capability, and more than 40 years of reliable operation.

They can also significantly enhance the electromagnetic compatibility (EMC) of the devices, effectively meeting system-level ESD, EFT, surge, and radiation compliance requirements.
