1.5kW Zener TVS with AEC-Q101 pedigree
The 1.5KE43AHB0G: That 36.8V standoff means it sits across a 36V nominal rail and stays off until a transient pushes past the 40.9V breakdown threshold.
Automotive-grade transient protection
For an ECU, BMS, or sensor module that sees under-hood or cabin temperatures, the -55°C to +175°C operating junction range covers the thermal envelope without derating. The 1500W rating at 10/1000µs is the peak-pulse power — the actual energy-handling capability depends on the pulse duration and duty cycle, but for the standard lightning-surge test waveform this part absorbs the full transient without secondary protection.
Sourcing and traceability
The bulk packaging (not tape-and-reel) is typical for through-hole power diodes — no reel fee, but the handling is manual at the pick-and-place level.
