Product details

28V standoff, 1.5kW peak pulse — clamping specs and what they mean

The 1.5SMCJ28A-AU_R1_000A1 is a unidirectional Zener-based TVS (Transient Voltage Suppressor) in the SMC (DO-214AB) package, qualified for automotive applications under AEC-Q101. At 28V reverse standoff the diode sits off-state; once the line exceeds the 31.1V minimum breakdown the device clamps the transient, limiting the peak at the protected node to 45.4V maximum while conducting 33A peak pulse (10/1000 µs waveform). The 1.5 kW peak pulse rating sets the energy the part can absorb in that 10/1000 µ event — enough to absorb an ISO 7637-2 automotive load-dump transient without propagating the spike downstream to the ECU or sensor IC.

150°C junction rating for under-hood transient suppression

The AEC-Q101 qualification covers temperature cycling, humidity bias, and electrical stress, giving the automotive supply chain the PPAP traceability and failure-in-time data that an AEC grade demands.

Surface-mount SMC tape-and-reel for automotive assembly

The part ships in tape-and-reel (TR) or cut-tape (CT) packaging, supporting standard SMT placement in high-volume ECU assembly.

Frequently asked questions

What is 1.5SMCJ28A-AU_R1_000A1's listed type on this Circuit Protection line?

It is classified as a Zener-type TVS (Transient Voltage Suppressor) diode. It is unidirectional with a single channel and is not listed as a power-line protection device — the clamping action suppresses voltage transients on the signal or power rail it guards, not the mains line.

What series is this part and what does that mean for automotive deployment?

The series is listed as Automotive, AEC-Q101 — Panjit International Inc. has qualified this part to the AEC-Q101 stress test standard for automotive discrete semiconductors. AEC-Q101 covers high-temperature operational life, temperature cycling, humidity bias, and surge testing, giving the part the failure-in-time and traceability data required for under-hood and chassis-domain automotive designs.
