The DO-214AC (SMA) package is a common surface-mount footprint for board-level protection in power supplies, industrial controls, and telecom equipment. ## Active production — no replacement needed Microchip lists the SMAJ64E3/TR13 as Active. The reverse standoff voltage of 64 V is the maximum continuous DC voltage the TVS can sit across without conducting. When a surge exceeds the minimum breakdown voltage of 71.1 V, the device starts clamping. The clamp voltage of 114 V at 4.4 A is the peak voltage the protected load sees during the surge — verify that the downstream components (MOSFETs, ICs, capacitors) are rated above 114 V at the expected surge duration. ## Sourcing and ordering for the BOM line The SMAJ64E3/TR13 is available through our distribution channel. Because it is an active Microchip part with no known end-of-life, lead times are standard for the DO-214AC package family.","metaTitle":"SMAJ64E3/TR13 – Microchip 64 V Zener TVS, 500 W, DO-214AC","metaDescription":"SMAJ64E3/TR13 Zener TVS diode from Microchip Technology. 64 V reverse standoff, 114 V clamp, 500 W peak pulse.
