Active production — 1500 W bidirectional TVS for 36.8 V rails
The 1.5KE43CA-E3/54: The 40.9 V minimum breakdown voltage ensures the device remains non-conductive below the rail voltage, while the 59.3 V clamp protects downstream silicon rated for 60 V or higher — a typical margin for 48 V telecom or 36 V battery bus transient suppression.
Bidirectional clamping and temperature range
The DO-201AA (DO-27) axial package provides a robust through-hole body with 0.042-inch diameter leads — suitable for point-to-point wiring or PCB mounting where the lead bend radius absorbs board flex away from the glass passivated junction.
Sourcing and compliance posture
No power line protection rating confirms this is a signal-line TVS — not intended for AC mains or high-energy industrial power bus clamping where larger footprint devices or MOVs would be specified.
