The On Semiconductor MMSZ18T1 is a 500 mW Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 18V with a tolerance of ±5%. The device operates over a temperature range of -55°C to 150°C.
This Zener diode is packaged in a compact SOD-123 surface-mount case, making it suitable for high-density applications and automated board assembly. The maximum power dissipation is rated at 500 mW on an FR-5 board at 75°C, with a derating of 6.7 mW/°C above that temperature. The thermal resistance junction-to-ambient is 340 °C/W.
Key electrical characteristics include a maximum forward voltage of 900 mV at 10 mA and a reverse leakage current of 50 nA at 12.6 V. The Zener impedance is a maximum of 45 Ω at the test current (IZT).
