DO-214AB (SMC)
5.0SMDJ45CA-N
5000 W bi-directional foldback (snap-back) TVS in DO-214AB. Snap-back clamping pulls residual voltage far below a standard suppressor of the same standoff, so the downstream MOS rating can stay where it is.

QWhat is the clamping voltage of 5.0SMDJ45CA-N?
58.1 V at a peak pulse current of 68.8A (10/1000 µs waveform), with a standoff voltage of 45 V and a breakdown window of 50.0–55.3V. It is a 5000W (10/1000µs, non-repetitive) device in DO-214AB (SMC) — the DO-214AB land pattern is the same one every standard SMC suppressor uses, so it drops into an existing 5.0SMDJ or SMDJ layout with no board change. Supplied by Shenzhen Intek Technology from the Anhui Amsemi Semiconductor line.

Questions engineers actually ask
What does the “-N” suffix mean on 5.0SMDJ45CA-N?
It marks the foldback (snap-back) version of the same voltage grade. Electrically it is the same standoff and the same breakdown window, but the clamping characteristic bends back after breakdown, so the residual voltage seen by the protected circuit is lower.
What is the clamping voltage of 5.0SMDJ45CA-N?
58.1 V at Ipp = 68.8A on a 10/1000 µs waveform. Standoff is 45 V and the breakdown window is 50.0–55.3V.
Is it automotive grade?
The AMSEMI factory holds AEC-Q101 qualification, and automotive versions are built to order with the suffix -H. Parts shipped from stock are industrial grade. Say which grade you need in the RFQ and both are quoted.
How much is in stock right now?
No shelf stock is listed for this voltage grade — it is built to order. Send the quantity you need and stock or lead time is confirmed within one business day.
Which documents come with it?
RoHS declaration, SGS test report and REACH statement are available on request for AMSEMI parts. The datasheet for this series is provided with the quotation.
