SZMMSZ4689T1G

The SZMMSZ4689T1G is a Zener voltage regulator diode from the SZMMSZ4xxxT1G series, designed for surface mount applications. It offers a nominal Zener voltage of 5.1V with ±5% tolerance and a maximum power dissipation of 500mW on FR-4 or FR-5 board. The device features low reverse leakage current of 10µA at 3V reverse voltage and a forward voltage of 900mV at 10mA. It is housed in a SOD-123 package, which is void-free, transfer-molded plastic. The case is rated UL 94 V-0 flammability and can withstand soldering temperatures up to 260°C for 10 seconds. The SZ prefix indicates automotive qualification with AEC-Q101 and PPAP capability. The device is Pb-Free and RoHS compliant. With an ESD rating of Class 3 (>16kV) per Human Body Model, it is suitable for robust applications. The operating temperature range is -55°C to 150°C. Thermal resistance junction-to-ambient is 340°C/W and junction-to-lead is 150°C/W. This diode is ideal for voltage regulation, clamping, and protection circuits in automotive, industrial, and consumer electronics.
