Device identity and key parametrics
The 1.5KE62A R0G: This defines the protection window: a 48 V bus or 53 V rail sees no leakage until a transient pushes past the standoff threshold.
Package and thermal envelope
Housed in a DO-201AA / DO-27 axial leaded package, the 1.5KE62A R0G is a through-hole part suited for boards where solder-joint reliability under thermal cycling matters more than board density. The axial body allows hand or wave soldering, and the lead spacing fits standard 0.4-inch pitch holes. The wide range means the diode can sit near hot components or in outdoor enclosures without derating the surge capability at the high end — the 1500 W rating holds across the full temperature band, though the peak pulse current may be derated above 25°C per the datasheet curve.
