SZMMSZ4704T1G

The SZMMSZ4704T1G is a 17V Zener diode from ON Semiconductor, part of the SZMMSZ4xxxT1G series designed for automotive and other applications requiring unique site and control change requirements. It offers a nominal Zener voltage of 17V with ±5% tolerance and a maximum power dissipation of 500mW on FR-4 or FR-5 board. Electrical characteristics include a low reverse leakage current of 50nA at 12.9V and a forward voltage of 900mV at 10mA. The device is rated for an operating temperature range of -55°C to 150°C and features an ESD rating of over 16kV per Human Body Model (Class 3).

The diode is housed in a void-free, transfer-molded SOD-123 surface mount package with a corrosion-resistant finish and polarity indicated by a cathode band. It is designed for optimal automated board assembly and is suitable for high-density applications. The package has a flammability rating of UL 94 V-0 and a maximum soldering temperature of 260°C for 10 seconds.

As an SZ-prefix device, this Zener diode is AEC-Q101 qualified and PPAP capable, making it suitable for automotive electronics. The datasheet indicates Pb-Free and RoHS compliant finish, though these compliance claims are unverified in the current data. Typical applications include voltage regulation, overvoltage protection, and clamping in low-power circuits.
