It delivers 500W peak pulse power per the 10/1000 µs waveform, with a minimum breakdown voltage of 37.1V and a maximum clamping voltage of 53.6V at the rated peak pulse current of 9.3A. ## Parametric profile for protection design The reverse standoff voltage is 29.7V typical, meaning the device does not conduct appreciably below that level — useful for protecting 28V rails or similar DC buses. With a single bidirectional channel and no power line protection feature, this part is best suited for signal or low-power DC bus clamping rather than AC mains suppression. The SQ-MELF package (B case) is a hermetic ceramic barrel — hand-solderable with care, but reflow or hot-air rework is typical. ## Active production and sourcing posture The base product number is 1N6120. Sourced to order against BOM quantities — confirm the SQ-MELF footprint and the 29.7V standoff threshold match your protection target before committing.","metaTitle":"1N6120AUS Zener Diode – 500W, 37.1V Breakdown, SQ-MELF","metaDescription":"1N6120AUS Zener diode from Microchip Technology. 500W peak pulse power, 37.1V breakdown, bidirectional, SQ-MELF surface mount.
