It clamps a 40.2V reverse standoff rail to a maximum of 64.8V at the rated Ipp, with a minimum breakdown voltage of 44.7V. The DO-201AD axial package suits through-hole board layouts where a single device guards a DC bus or signal line against surges. onsemi lists the 1N6287ARL4 as Obsolete. Sourcing is limited to independent-distributor inventory and surplus stock — we can quote to order against your BOM quantity from available market lots. Confirm the date-code range and quantity needed at quote time. ## Peak pulse power and voltage selection The 1500W peak pulse power is specified at 25°C — derate linearly above that per the datasheet curve. The 40.2V reverse standoff voltage is the maximum DC or peak AC voltage the device can withstand without conducting; the 44.7V minimum breakdown is where avalanche begins. The 64.8V clamping voltage at Ipp is the peak voltage the protected circuit sees during a surge event. Operating temperature range spans -65°C to 175°C junction, covering industrial and some military-ambient environments.","metaTitle":"1N6287ARL4 onsemi Mosorb™ Zener TVS 1500W DO-201AD Obsolete","metaDescription":"onsemi 1N6287ARL4 Mosorb™ Zener TVS diode, 1500W peak pulse power, 40.2V standoff, DO-201AD axial.
