It delivers 1500W peak pulse power (1.5kW) in a through-hole DO-201AD axial package, supplied on Tape & Reel for automated insertion. ## Clamping voltage and breakdown margin With a minimum breakdown voltage of 25.9V and a maximum clamping voltage of 37.5V at rated peak pulse current, this part provides a 3.9V margin above the 22V standoff before avalanche. That window suits protection of 24V bus lines where the steady-state rail sits at 22V or below. ## Obsolete — sourcing through distribution onsemi lists the 1N6379RL4 as Obsolete. For BOM lines requiring this exact order code, we source through our authorized and independent supply channels — quoted per RFQ against your target quantity. ## Temperature range and environment fit Rated for operation from -65°C to 175°C junction temperature, this diode handles the thermal extremes of industrial motor drives, outdoor telecom enclosures, and underhood automotive electronics. The DO-201AD axial body is a standard through-hole footprint, easily hand-soldered or wave-soldered on single-sided boards.","metaTitle":"1N6379RL4 onsemi Mosorb™ Zener TVS Diode 1500W DO-201AD","metaDescription":"onsemi 1N6379RL4 Mosorb™ Zener TVS, 1500W peak pulse, 22V standoff, 37.5V clamp.

Submit an RFQ with your target quantity and we will confirm pricing and lead time against available stock. No stock-holding claim is made here."},{"question":"What is the replacement for 1N6379RL4?","answer":"onsemi has not published an official successor for the 1N6379RL4. For a 22V rail requiring 1500W peak pulse in a DO-201AD axial package, consider the 1N6379 (base part without Tape & Reel suffix) if still available, or cross-reference to a current Littelfuse or Vishay Zener TVS with matching standoff and clamping voltages. We can assist with cross-referencing on request."},{"question":"What is the difference between 1N6379 and 1N6379RL4?","answer":"The 1N6379RL4 is the Tape & Reel packaging variant of the base part 1N6379. Electrically identical — same 22V standoff, 25.9V breakdown, 37.5V clamp, 1500W rating. The RL4 suffix indicates reel packaging for automated assembly; the base 1N6379 may come in bulk or other packaging."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/1N6379RL4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/1N6379RL4 when reusing this data.
