The SZMMSZ5250ET1G is a 20V Zener diode from On Semiconductor's SZMMSZ52xxET1G series, designed for voltage regulation and protection in low-power applications. It offers a nominal Zener voltage of 20V with ±5% tolerance and a maximum power dissipation of 500mW on FR-4 or FR-5 boards.
Key electrical characteristics include a maximum impedance of 25Ω at the Zener test current, reverse leakage current of 100nA at 15V, and a forward voltage of 900mV at 10mA. The device is rated for peak power dissipation of 225W under non-repetitive 8x20µs pulses and features an ESD rating exceeding 16kV per Human Body Model (Class 3).
The diode is housed in a surface mount SOD-123 package, suitable for automated assembly. It supports an operating temperature range of -55°C to 150°C, with junction-to-ambient thermal resistance of 340°C/W and junction-to-lead resistance of 150°C/W. The package is rated UL 94 V-0 for flammability and is available in tape and reel packaging with 3000 units per reel.
