For engineers reviewing the SMBJ160AHM3_A/H datasheet, SMBJ160AHM3_A/H pinout, SMBJ160AHM3_A/H application, or SMBJ160AHM3_A/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (−55 to +150 °C), and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker testing.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging an avalanche breakdown mechanism to limit transient overvoltages before they damage downstream ICs or MOSFETs. Its low incremental surge resistance and fast response time (<1 ns) ensure effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
The SMBJ160AHM3_A/H is rated for 600 W peak pulse power (10/1000 µs), 5.0 W steady-state power dissipation at 50 °C, and 100 A non-repetitive forward surge current (8.3 ms half-sine). It meets MSL Level 1 per J-STD-020 and is halogen-free, RoHS-compliant, and AEC-Q101 qualified - confirming suitability for automotive-grade power supply protection.
