TransZorb 1500 W TVS for general-purpose rail clamping
The 1.5KE24A-E3/73: The 1500 W rating means this part absorbs single-event surges up to that power level — a 24 V nominal rail hit by an inductive load dump or lightning-induced transient gets clamped before the downstream circuitry sees overvoltage. The 33.2 V clamp is the ceiling; the protected equipment must survive that peak for the pulse duration.
Through-hole axial package and temperature range
Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE24A-/73 mounts through-hole — the body sits in free air or against a heatsink pad, with the leads soldered into the board or terminated in a socket. The wide temperature range and axial package suit it for power supplies, motor drives, and telecom line cards where the TVS is soldered into a PCB alongside electrolytic capacitors and magnetics that see elevated internal temperatures.
