Product details

Obsolete — last-time-buy sourcing reality

The 1.5KE22-E3/54: Vishay lists the 1.5KE22-/54 as Obsolete.

1500W clamping — what the ratings mean for the board

When a transient exceeds the 19.8 V minimum breakdown voltage, the diode clamps the surge to 31.9 V maximum while shunting up to 47 A peak pulse current.

DO-201AA axial — board-fit note

Through-hole axial package in DO-201AA (DO-27) form factor. The 1.5KE body diameter and lead spacing are standard for this power class — the leads are tin-plated copper, solderable in wave or hand-solder processes. No power line protection means it is a unidirectional clamp for signal or DC supply rails, not an AC mains protector.
