Ultra-small package 1A/40V Schottky diode

A DFN1006 small package, 1A, 40V, low dropout Schottky diode is widely applied in fields such as smart wearables, mobile power supplies, and 5G communication, which are highly sensitive to space size and efficiency. It provides multiple guarantees for circuit design in terms of space, efficiency and reliability.
UNRD0610（Solid-state relay SSR）

Fast switching speed, no spark, no noise, low electromagnetic interference, strong anti-interference ability, long life and high reliability and other excellent performance
Power protection module

Compatible with OVP and eFuse, it can quickly shut down the output with a microsecond response speed when the supply input voltage exceeds the OVP threshold or the load current exceeds the OCP threshold, thereby protecting the back-end circuit from damage. Simple wiring and easy-to-understand functional design reduce the user's threshold of use, providing customized parameter design services to meet specific application needs.
Vehicle load protection module LDP

The load throwing protection module is an overvoltage protection element specially designed for DC power supply ports.
Composite surge protection device GMOV

With its compact design, the GMOV device can directly replace the standard 10D or 14D varistor MOV and achieve zero leakage in the application circuit. In addition, its low parasitic capacitance characteristics enable it to adapt to the needs of various signal ports. In terms of performance and reliability, GMOV devices significantly surpass traditional varistor MOV.
14D Enhanced Varistor

1.2/50uS & 8/20uS combination of wave, 6KV/3KVA sub 0 ， 90 ，180，270 four phases,each phases of positive and negative 5 times Total 40 times .
