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.
