The clamping voltage at that peak pulse current is 41.4 V max, meaning a 25.6 V nominal rail sees the spike clipped to that ceiling before the TVS conducts the 36.2 A pulse to ground. A single bidirectional channel covers transients of either polarity, so a single device protects an AC signal line or a bipolar DC rail without needing two back-to-back unidirectional parts. The breakdown voltage starts at 28.5 V minimum, with a reverse standoff of 25.6 V typical — the rail should stay below that standoff to avoid leakage in normal operation. ## Through-hole axial — legacy footprint, high-reliant mounting The DO-201AA / DO-27 axial-lead package is a through-hole form factor that has been a workhorse in industrial and telecom boards for decades. The leads are soldered into plated through-holes, giving a mechanically robust joint that handles thermal cycling better than a small surface-mount package. The 1.5KE series supplier device package designation (1.5KE) is shared across the family, so the PCB footprint is consistent across voltage variants within the series. ## General-purpose application — not limited to a single market Vishay lists the application as general purpose, meaning the TVS is suited for protecting DC power rails, signal lines, and low-voltage AC circuits in industrial controls, telecom equipment, automotive electronics, and consumer goods. Power line protection is explicitly not supported — do not use this part on mains AC (120/230 V) lines; it is designed for the low-voltage side of the system.","metaTitle":"1.5KE30CA-E3/73 Vishay TransZorb TVS, 1500W, Bidirectional","metaDescription":"1.5KE30CA-E3/73 Vishay TransZorb bidirectional Zener TVS, 1500W peak pulse, 25.6V standoff, 41.4V clamp, DO-201AA axial, active production, available to order.","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 & Box (TB)","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":"1.5KE30","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"28.5V","Voltage - Clamping (Max) @ Ipp":"41.4V","Voltage - Reverse Standoff (Typ)":"25.6V","Current - Peak Pulse (10/1000µs)":"36.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4460","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/1.5KE30CA-E3-73","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/1.5KE30CA-E3-73 when reusing this data.
