A narrower window means less stress on the protected silicon, but the trade-off is higher standby leakage at the upper end of the operating range. ## Breakdown tolerance and temperature range Minimum breakdown voltage (V_BR) is 162 V at 1 mA test current. The actual breakdown voltage shifts with junction temperature — the datasheet's temperature coefficient for Zener-type TVS diodes is typically positive, so at 175 °C the V_BR rises by roughly 10–12 V from the 25 °C value. The operating junction temperature range spans -55 °C to 175 °C, covering the full industrial and automotive under-hood thermal envelope. ## Package and board integration Housed in the DO-201AA (DO-27) axial-lead package, the 1.5KE170A-/54 is a through-hole device. The body diameter and lead spacing match the standard 0.375-inch (9.5 mm) lead-to-lead footprint used across the TransZorb® family. For high-reliability builds, the leads should be formed with a minimum bend radius of 1.5 mm from the glass seal to avoid cracking the package body.","metaTitle":"1.5KE170A-E3/54 Vishay TVS, 1500W, 145V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE170A-E3/54 TransZorb® TVS diode, 1500W peak pulse, 145V reverse standoff, 234V clamp, unidirectional, DO-201AA axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"TransZorb®","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE170","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"162V","Voltage - Clamping (Max) @ Ipp":"234V","Voltage - Reverse Standoff (Typ)":"145V","Current - Peak Pulse (10/1000µs)":"6.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3246","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE170A-E3-54","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE170A-E3-54 when reusing this data.
