Product details

AEC-Q101 TVS — 1500 W peak pulse in a DO-214AB

The 1.5SMC18AHE3/9AT: It is AEC-Q101 qualified, meaning it meets the automotive discrete semiconductor reliability and temperature-grade requirements for use in vehicle electronics.

Clamping performance — 25.2 V max at 59.5 A

The maximum clamping voltage is 25.2 V at a peak pulse current of 59.5 A (10/1000 µs waveform), limiting the transient energy seen by the downstream circuitry. The operating junction temperature range spans -65°C to +150°C, covering the full under-hood and engine-bay thermal profile required by AEC-Q101 Grade 0 applications.

The DO-214AB package is tape-and-reel packaged, compatible with standard pick-and-place assembly.

Frequently asked questions

Where can I buy the 1.5SMC18AHE3/9AT and how is it quoted?

The 1.5SMC18AHE3/9AT is sourced through independent and authorized distribution channels. Submit an RFQ for a firm quotation.

What is the AEC-Q101 grade for the 1.5SMC18AHE3/9AT?

The series is AEC-Q101 qualified, which certifies it for automotive-grade discrete semiconductor reliability, including the -65°C to +150°C operating temperature range. This qualifies it for under-hood and engine-bay applications where Grade 0 is required.
