MMSZ5229C-E3-18

Vishay MMSZ5229C surface-mount Zener diode in a SOD-123 package. Nominal Zener voltage is 4.3 V at 20 mA with ±2% tolerance. Maximum dynamic resistance is 22 Ω at 20 mA. Maximum reverse leakage is 5 µA at 1 V. Maximum power dissipation at 25 °C is 500 mW at 250 K/W junction-to-lead thermal resistance, or 300 mW on FR-4 with Vishay’s recommended solder footprint. Operating temperature is −55 to +150 °C. Supplied on a 10,000-piece reel.
