1.5kW TransZorb — clamping and fit for 24V rails
The 1.5KE27A-E3/73: When a surge hits, the diode clamps at 37.5V maximum while shunting 40A of peak pulse current (10/1000 µs waveform).
Package and temperature envelope
The through-hole axial DO-201AA package suits point-to-point wiring or PCB through-hole mounting where the lead bend radius is controlled. No power-line protection feature is built in — this is a standard TVS for signal or DC bus clamping, not for AC mains cross-coupled protection. The Tape & Box packaging (/73 suffix) is a Vishay-specific reel-less format, not a standard tape-and-reel; factor this into pick-and-place handling if feeding from a tube or tray adapter.
Availability is confirmed per RFQ; pricing and lead time are quoted against the BOM quantity through independent distribution channels. The base product number 1.5KE27 covers the full family; the -/73 suffix denotes the Vishay Green/ROHS-compliant build and the Tape & Box packaging variant.
