Active production — a current-design TVS for 53 V rails
The 1.5KE62A-E3/54: This clamping voltage is the number that matters for downstream device stress — a 100 V-rated MOSFET on the rail sees 15 V of headroom at the clamp limit.
Thermal and mechanical fit for industrial power supplies
Operating junction temperature range spans -55°C to 175°C, which covers the full industrial temperature envelope including hot-side DC bus applications in motor drives and power supplies. The DO-201AA (DO-27) axial-leaded through-hole package provides a mechanically robust mount for high-reliability connections — the lead bends absorb board flex better than a surface-mount part. Power line protection is not supported, so this device is intended for signal-line or DC rail transient suppression rather than AC mains clamping. The 1500 W rating at 10/1000 µs waveform is the standard TVS surge rating — derate for shorter pulse widths per the datasheet's peak-pulse-power vs pulse-duration curve.
Sourcing posture for the BOM line
As an active Vishay part, the 1.5KE62A-/54 is sourced through authorized distribution channels. The base product number 1.5KE62 covers the full family; the -/54 suffix indicates the lead-free finish and tape-and-reel packaging.
