The 18.8 V reverse standoff voltage means this diode will not conduct on a nominal 18 V rail, but it begins to avalanche at a minimum of 20.9 V. The clamping voltage caps at 30.6 V when the peak pulse current reaches 102 A (8/20 µs waveform). For a design engineer, the margin between the rail voltage and the breakdown threshold determines how much transient overvoltage the system can ride through before the diode starts shunting current; the clamping voltage then tells the downstream components the maximum voltage they will see during a surge event. There is no last-time-buy risk or obsolescence pressure on this order code today.","metaTitle":"STMicroelectronics SM6T22CA TVS Diode, 600 W, Bidirectional","metaDescription":"STMicroelectronics SM6T22CA bidirectional TVS diode, 600 W peak pulse power, 18.8 V standoff, 30.6 V clamp, DO-214AA (SMB).
