The MMSZ5257B is a 33V Zener diode from On Semiconductor, part of the MMSZ52xxB series. It features a nominal zener voltage of 33V with a tolerance of ±5%, ensuring a voltage range of 31.35V to 34.65V. The device is rated for a maximum power dissipation of 500mW, suitable for low-power voltage regulation and protection applications.
Key electrical characteristics include a maximum impedance of 58Ω at 20mA test current and 700Ω at 0.25mA test current. Reverse leakage current is limited to 100nA at 25V reverse voltage. The forward voltage is 0.9V maximum at 10mA forward current. The diode operates over a temperature range of -55°C to 150°C, with a junction temperature maximum of 150°C.
The MMSZ5257B is packaged in a SOD-123 surface mount package, which is designed for automated assembly. The thermal resistance junction-to-ambient is 340°C/W on standard FR-4 PCB with minimum recommended land pads. This part is suitable for voltage clamping, reference, and regulation in compact electronic designs.
