SZMMSZ5256BT1G Description

Short technical summary and product information.

The SZMMSZ5256BT1G is a 30V Zener diode from On Semiconductor's SZMMSZ52xxxT1G series, designed for voltage regulation and protection in automotive and general-purpose applications. It offers a nominal Zener voltage of 30V with ±5% tolerance and a maximum power dissipation of 500mW when mounted on FR-4 or FR-5 boards.

 

This device features a maximum impedance of 49Ω at the Zener voltage, and a low forward voltage of 900mV at 10mA. Reverse leakage current is limited to 100nA at 23V. The diode is rated for operation over a junction temperature range of -55°C to +150°C, with thermal resistance of 340°C/W junction-to-ambient and 150°C/W junction-to-lead.

 

The SZMMSZ5256BT1G is housed in a compact SOD-123 surface mount package, designed for automated assembly and high-density PCB layouts. It is Pb-free and AEC-Q101 qualified for automotive applications. The device has an ESD rating of Class 3 (>16 kV) per the Human Body Model and meets UL 94 V-0 flammability rating. It is supplied in tape and reel packaging with 3000 units per reel.
