Sourcing is per RFQ against the BOM quantity — availability and pricing confirmed at quote time. ## 1500W peak pulse power in a DO-201AD axial package This is a single unidirectional Zener TVS diode rated for 1500W peak pulse power at 10/1000 µs waveform. The 10.2V reverse standoff voltage and 11.4V minimum breakdown voltage set the clamping threshold at 16.7V max. The DO-201AD axial package is through-hole mounted — the lead bend and body length are standard for this power level, so the PCB footprint matches any 1N6273-series socket. ## Temp range and application fit Junction temperature range is -65°C to 175°C, which covers military and industrial environments. No power line protection — this is a signal-rail or low-voltage DC bus clamp, not a mains-side suppressor. The Mosorb™ series is a standard onsemi TVS family; the 1N6273ARL4 is the tape-and-reel variant of the base 1N6273A.","metaTitle":"1N6273ARL4 onsemi Mosorb™ Zener TVS 1500W DO-201AD Obsolete","metaDescription":"onsemi 1N6273ARL4 Mosorb™ Zener TVS diode, 1500W peak pulse power, 11.4V breakdown, DO-201AD axial.

The base number 1N6273A (without the RL4 tape-and-reel suffix) is the same die in the same DO-201AD package — functionally identical, just different packaging format. For a direct parametric match, any 1500W, 10.2V standoff, 11.4V breakdown, 16.7V clamping TVS in DO-201AD will fit the same PCB footprint."},{"question":"How does 1N6273ARL4 compare to the 1N6273A?","answer":"The 1N6273ARL4 is the tape-and-reel packaged variant of the base 1N6273A. All electrical ratings — 1500W peak pulse power, 10.2V standoff, 11.4V breakdown, 16.7V clamping — are identical. The only difference is the packaging format: RL4 indicates tape-and-reel for automated assembly; the base 1N6273A is typically supplied in bulk or ammo pack."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/1N6273ARL4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/1N6273ARL4 when reusing this data.
