1.5kW unidirectional TransZorb — clamping profile for 24V rails
The 1.5SMC24A-E3/9AT: Its 20.5V reverse standoff voltage and 33.2V clamping point make it a fit for protecting 24V DC buses and signal lines where the normal operating rail sits below 20.5V and the clamp triggers before the downstream IC's abs-max rating. The 45.2A peak pulse current rating (Ipp at 10/1000µs) tells you the diode can sink a substantial surge without exceeding the junction temperature limit — useful for inductive kickback or lightning-induced transients on a 24V control loop.
Package and temperature — DO-214AB with 150°C junction ceiling
Surface-mount DO-214AB (SMC) package, supplier device package designated DO-214AB (SMCJ). Supplied on Tape & Reel — the reel quantity matches standard pick-and-place feeders for the SMC footprint. No power-line protection feature (the diode is intended for signal/data line clamping, not AC mains).
Active lifecycle — no last-time-buy planning needed
The same die in different packaging (bulk, different reel size) shares the same clamping profile.
