Zener unidirectional TVS diode, 40V reverse standoff, 1.5kW peak pulse power, 64.5V clamping, DO-214AB SMC surface mount, Tape & Reel.","salesMarkdown":"## 1.5kW unidirectional TVS in DO-214AB The 1.5SMCJ40AS_R1_00001: Its reverse standoff of 40 V sets the working voltage below which the device stays dormant — transients that exceed the 44.4 V minimum breakdown voltage trigger the clamping action, clamping at 64.5 V maximum to protect downstream circuitry. ## SMC package for surface-mount board assembly The DO-214AB (SMC) package mounts flush to the PCB with a solder reflow profile; the cathoded band marks the unidirectional polarity direction on the board. It ships in Tape & Reel or Cut Tape for standard pick-and-place assembly lines. ## General-purpose protection for power and signal rails Listed for general-purpose use, meaning it protects power rails, control lines, and data ports against lightning-induced transients and switching surges on the secondary side of a supply. It is not a power-line protection device — the datasheet confirms Power Line Protection: No.","metaTitle":"Panjit 1.5SMCJ40AS_R1_00001, 40V TVS Diode 1.5kW","metaDescription":"Panjit International Inc.

When a transient exceeds the 44.4 V breakdown threshold, the device clamps the peak voltage at the protected node to no more than 64.5 V, limiting the energy delivered to downstream components."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panjit-international-inc/1.5SMCJ40AS_R1_00001","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/panjit-international-inc/1.5SMCJ40AS_R1_00001 when reusing this data.
