Product details

185 V standoff, 1500 W pulse — automotive-grade transient clamp

The 1.5SMC220AHM3_A/I: AEC-Q101 qualification means this part is screened for automotive reliability — it is suitable for load-dump and transient suppression on 185 V nominal rails in engine bay or chassis-domain electronics where the ambient temperature range spans -65 to 150 °C.

The single unidirectional channel means polarity must be observed in layout: the cathode band on the package marks the protected rail side, and the anode connects to ground.

Target applications include automotive and telecom equipment, where the 185 V standoff and 1500 W pulse rating cover transient protection for 185 V nominal DC buses or AC rectified lines.

Frequently asked questions

What is the 1.5SMC220AHM3_A/I's clamping voltage and standoff rating?

The reverse standoff voltage is 185 V typical, and the maximum clamping voltage at 4.6 A peak pulse current is 328 V. This defines the transient suppression envelope for a 185 V nominal rail.

What compliance documentation does Vishay provide for this part?

The part is AEC-Q101 qualified for automotive applications. Standard Vishay documentation includes the datasheet, RoHS/REACH compliance certificates, and AEC-Q101 test reports — available through the manufacturer's document portal or upon request with an RFQ.
