No official second-source or successor is listed on the record, but the 1N6123A base number is shared across the family, so a same-function sibling with a different clamping voltage (e.g., 1N6123A vs 1N6123) would share the same footprint.","metaTitle":"1N6123A Bidirectional TVS Diode – 500W, 38.8V Standoff","metaDescription":"1N6123A from Microchip Technology: Zener TVS, 500W peak pulse power, 38.8V standoff, bidirectional, Axial package, -55°C to 175°C.
