Zener TVS for 90 V rail protection
Its 100 V minimum breakdown voltage ensures the device stays off during normal operation but fires before the protected circuit sees damaging overvoltage. The 146 V clamping voltage at 4.1 A gives the downstream components a hard voltage ceiling — useful when the rail feeds a DC-DC converter input or a relay coil driver.
Parametric fit for 90 V rail clamping
With a 90 V reverse standoff and 100 V minimum breakdown, this part sits above a 72 V or 80 V rail but below a 100 V rail — it is not a catch-all. The 4.1 A peak pulse current at the clamping voltage is the current the diode must survive; if your transient source impedance is very low, the actual peak current may exceed this, so check the Ipp vs. waveform curve.
Because the part is active, lead times are generally manageable through distribution. We source this against your BOM quantity at the time of quote — no stock-holding claim, but the supply channel is open.
