Product details

DO-214AB package and clamping ceiling at 85V

The 1.5SMC62CA-Q: With a reverse standoff of 53 V, it clamps at a maximum 85 V during a 10/1000 µs surge event — this 32 V clamping ceiling is the headroom that protects a 48 V telecom rail or an automotive 12 V bus through its ignition transients.

AEC-Q101 qualification and the -55 to 150°C junction window

The automotive and telecom application tag tells you this part was screened for load-dump, cold-crank, and surge-compatibility testing — the AEC-Q101 suffix is not decorative, it means the wafer lot traceability and a defined PPAP package are available to the automotive OEM or Tier 1.

If your suppression target is a slower, higher-energy surge (8/20 µs IEC 61000-4-5), derate the peak current accordingly — the same clamping voltage applies but the dissipated energy is higher, so thermal runway on the junction side of the tab becomes the limiting factor.

Frequently asked questions

What is the 1.5SMC62CA-Q used for in an automotive design?

The part protects low-voltage rails against load-dump and reverse-battery transients on the 12 V bus or 48 V mild-hybrid nets — the AEC-Q101 qualification means it is cleared for direct integration into engine-control and body-control modules without a separate qualification step.

What does the clamping voltage of 85V mean for a 53V rail?

The 32 V headroom between the 53 V standoff and the 85 V clamping ceiling absorbs the spike and clamps the downstream circuit below the absolute-maximum rating of most downstream ICs — it is not a guarantee against all transients, but a properly sized peak pulse event stays within it.
