SZMM3Z12VST1G Description

Short technical summary and product information.

The SZMM3Z12VST1G is a surface mount Zener diode from On Semiconductor, designed for voltage regulation in space-constrained applications. It provides a nominal Zener voltage of 12V with a tolerance of ±2%. The device can dissipate up to 300mW of power. Key electrical characteristics include a maximum impedance of 25Ω, reverse leakage current of 100nA at 8V reverse voltage, and a forward voltage drop of 900mV at 10mA forward current. The diode is housed in a compact SOD-323 (SC-76) package, making it suitable for high-density PCB designs. Operating temperature range is -65°C to 150°C. The SZ prefix indicates automotive qualification (AEC-Q101) as per the datasheet, though this is not independently verified.
