The ±5% tolerance on the nominal voltage means the actual Zener voltage falls between 20.9 V and 23.1 V at the specified test current — tight enough for most rail-clamp and reference applications in that band. ## Wide-temperature Zener for harsh environments Operating from -65°C to 175°C, this diode covers the full military temperature range. The SQ-MELF package is a hermetic, surface-mount ceramic barrel — the same construction used in high-reliability and aerospace builds where a plastic SMD package would risk moisture ingress or thermal-cycle fatigue. The 500 mW power ceiling is derated above 25°C; at 175°C the allowable dissipation drops to near zero, so the actual junction temperature under load must be calculated from the thermal resistance of the solder joint and board.","metaTitle":"1N6332US Zener Diode, 22 V, 500 mW, SQ-MELF, Microchip","metaDescription":"Microchip 1N6332US Zener diode, 22 V nominal, 500 mW, ±5% tolerance, SQ-MELF B package, -65 to 175°C.
