QCan 5.0SMDJ75CA-N replace 5.0SMDJ75CA without changing the PCB?
Yes. 5.0SMDJ75CA-N and 5.0SMDJ75CA are the same footprint — DO-214AB (SMC), same land pattern, same reel — so the swap is a BOM change only. Standoff voltage is identical at 75 V and the breakdown window is the same, but the clamping voltage drops from 121.0 V to 96.8 V (20.0% lower) at the same 41.4 A (10/1000µs) pulse current, which is what lets the downstream MOS rating stay where it is. Both are supplied by Shenzhen Intek Technology from the AMSEMI line.

Read the Δ column carefully. The 20.0% is a clamping-voltage reduction, not a
power-rating upgrade. Both devices absorb the same 10/1000 µs pulse at the same current — what
changes is how much of that energy reaches the MOSFET behind them. If a design already passes with
5.0SMDJ75CA, it passes with 5.0SMDJ75CA-N with more margin; if it fails on clamp,
5.0SMDJ75CA-N is the drop-in fix — no layout change, no requalification of the land pattern.
When to use it and when not to
Good fit
- BMS protection boards where the residual clamp is what sets the MOSFET rating
- Existing 5.0SMDJ75CA designs that fail a surge test on clamp voltage — swap to 5.0SMDJ75CA-N with no layout change
- Retrofit work where the land pattern is fixed and requalification is expensive
- Bus voltages up to roughly 82 V with the 75 V standoff grade
Not the right part
- Where you need more surge current — go up a power grade (SMDJ → 5.0SMDJ → 8.0SMDJ), not across the -N line
- Footprints other than DO-214AB: a smaller package is a board redesign, not a substitution
- Signal-line ESD clamping — this is a 5 kW surge device, use an ESD array instead
Questions engineers actually ask
What is the clamping voltage of 5.0SMDJ75CA?
121.0 V at Ipp = 41.4 A (10/1000µs) on a 10/1000 µs waveform. Standoff is 75 V and the breakdown window is 83.30-92.10 V @ IT=1 mA.
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?
24,200 pcs as of 2026-09-18. Stock is counted periodically rather than in real time, so confirm the quantity you need when you request the quote.
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.
