What is the difference between high-power TVS diode and low-power TVS diode?

1. PN junction: The PN junction between high-power TVS and low-power TVS is different. High-power TVS diode has a large heat sink, while low-power TVS diode does not.

What is the difference between high-power TVS diode and low-power TVS diode?

Ii. Junction capacitance: The junction capacitance of high-power TVS can be up to hundreds of pF; The junction capacitance of low-power TVS can be less than 0.3PF;

Iii. Power: 8/20US waveform is used for low-power TVS performance test; The 10/700US waveform is used in the performance test of high-power TVS, whose power is 7-10 times that of low-power TVS tube.

Iv. Response speed: The response speed of low-power TVS is PS level; High-power TVS generally have a speed of <1ns or 5ns;

V. Packaging: Large-power TVS are generally packaged in SMC, DO-218AB, R-6/P600 and NA, with large size;

Six, low-power TVS, the package is generally SOD-123, DO-214AC, DO-41, DO-15, DO-214AA, small size;

Vii. Application: High-power TVS diode is mainly used in power line; Low-power TVS is mainly used in high-density installation.
