Product details

1500W Zener TVS – 23.1V standoff, 37.5V clamp

The 1.5SMC27AT3 is a single-channel unidirectional Zener TVS diode from onsemi, rated for 1500W peak pulse power at 10/1000µs waveform. Its 23.1V reverse standoff voltage protects 24V nominal rails, clamping transients to 37.5V at 40A peak pulse current.

DO-214AB SMC – surface-mount footprint

Housed in the DO-214AB (SMC) package, this part is surface-mount and intended for general-purpose circuit protection across a -65°C to 150°C junction temperature range.

Obsolete – sourcing via RFQ

onsemi has marked the 1.5SMC27AT3 as Obsolete. For BOM continuity, we source this part against your quantity via RFQ – confirm availability and current pricing at quote time.

Frequently asked questions

How can I order 1.5SMC27AT3 or check availability?

Submit an RFQ with your target quantity. We source obsolete onsemi parts against the BOM line – availability and pricing confirmed at quote time, no stock-holding claim.

Is 1.5SMC27AT3 obsolete?

Yes, onsemi lists the product status as Obsolete. No direct replacement has been published by the manufacturer.

What is the replacement for 1.5SMC27AT3?

No official replacement is recorded. A functionally similar part in the same 1.5SMC family (e.g., 1.5SMC27A) may be considered, but pin-to-pin compatibility and electrical ratings must be verified against your design.

What does the T3 suffix on 1.5SMC27AT3 mean?

The T3 suffix typically denotes tape-and-reel packaging. The base product number is 1.5SMC27A.
