This is the rail-protection decision point — if the transient exceeds 49.9 V, the TVS shunts the energy to ground before the downstream regulator sees it. ## Obsolete — sourcing through surplus channels Vishay lists this part as obsolete. The part is available through independent surplus and auction-lot channels; quantities are lot-specific, date-code spreads vary, and pricing is confirmed at RFQ. ## Through-hole package and temperature range That temperature grade suits it for power supplies, industrial controls, and telecom rectifiers where the ambient inside the enclosure can exceed 85°C. The axial leads allow point-to-point wiring or PCB through-hole mounting — no surface-mount reflow profile needed.","metaTitle":"1.5KE36A/54 Vishay TransZorb TVS, 30.8V Standoff","metaDescription":"Obsolete Vishay 1.5KE36A/54 Zener TVS diode, 1500W peak pulse, 30.8V reverse standoff, 49.9V clamp.
