The 53.9 V clamp voltage is the hard limit the downstream circuitry must survive — if your 36 V bus sees a transient, the diode holds it under 54 V, which is well within the 60 V abs-max of many downstream DC-DC converters and linear regulators. ## Package and board integration Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE39A-/54 is a through-hole part — it stands off the board and can be hand-soldered or wave-soldered. The axial body is common for TVS diodes in this power class, and the lead spacing fits standard 0.3-inch pitch holes. The wide range means the diode's leakage and breakdown voltage drift remain within spec across the full temperature swing. ## Lifecycle and supply posture The base product number is 1.5KE39, and the suffix -/54 indicates the lead-free, RoHS-compliant version in tape-and-reel packaging. Cut tape options are also listed.","metaTitle":"Vishay 1.5KE39A-E3/54 TransZorb TVS, 33.3V Standoff, 1500W","metaDescription":"Active Vishay 1.5KE39A-E3/54 TransZorb Zener TVS diode, 33.3V reverse standoff, 53.9V clamp, 1500W peak pulse, DO-201AA.
