AEC-Q101 qualified 1500W TVS for automotive bus protection
The 1.5SMC120AHM3/I: It clamps transients at 165V maximum, with a 102V reverse standoff voltage and a minimum breakdown of 114V.
Package, temperature range, and board-fit considerations
Housed in the DO-214AB (SMC) package, the 1.5SMC120AHM3/I is a surface-mount device with a standard footprint shared across the 1.5SMC family. The operating junction temperature spans -65°C to 150°C, covering under-hood ambient and cold-crank conditions without derating the 1500W peak pulse capability. The 9.1A peak pulse current at the 10/1000µs waveform defines the surge-handling limit; for shorter pulses (8/20µs), the peak current capability is higher, but the datasheet's power derating curve above 25°C must be applied for sustained operation near the 150°C junction limit.
Lifecycle and compliance status
The 1.5SMC120AHM3/I carries AEC-Q101 automotive qualification, which includes PPAP documentation and traceability for production lots. No RoHS or REACH compliance status is explicitly stated in the available record, but the TransZorb series is typically RoHS-compliant; verify the specific date-code lot at order.
