Product details

1500 W peak pulse — clamping a 70.1 V rail

The 1.5KE82A-E3/54: It clamps transients at 113 V when the peak pulse current reaches 13.3 A, protecting downstream silicon on a 70.1 V reverse standoff rail. The 77.9 V minimum breakdown voltage gives a guard band above the 70.1 V standoff — the diode stays transparent during normal line operation but fires before the rail exceeds the safe operating area of the load.

DO-201AA axial — board-level transient protection

Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE82A-/54 mounts into a standard 0.100-inch pitch hole pattern. The wide temp window means no derating is needed at 85 °C ambient for the full 1500 W rating.

Active lifecycle — sourced per RFQ

The base product number is 1.5KE82; the -/54 suffix denotes the lead-free termination and the tape-and-reel packaging option. No pin-compatible second source is formally cross-referenced, but the TransZorb family covers the same DO-201 footprint across voltage grades.

Frequently asked questions

What does the 1500 W peak pulse rating mean for my circuit?

The 1500 W rating is the peak pulse power the diode can absorb for a 10/1000 µs waveform without failing. For a 70.1 V rail, the 113 V clamping voltage at 13.3 A peak pulse current means the TVS holds the transient below the breakdown voltage of most downstream 100 V-rated semiconductors.

What package does the 1.5KE82A-/54 use?

It comes in a DO-201AA (DO-27) axial-lead through-hole package. The leads are tin-plated and compatible with standard 0.100-inch pitch PCB hole patterns.
