The MMSZ5244B is a 14V Zener Diode from On Semiconductor, designed for low-power voltage regulation and reference applications. It delivers a nominal zener voltage of 14V with a tolerance of ±5%, and a typical voltage range of 13.3V to 14.7V at a test current of 20mA. The diode offers a low zener impedance of 15Ω at 20mA, ensuring stable voltage regulation. Reverse leakage current is limited to 100nA at a reverse voltage of 10V, and forward voltage is 900mV maximum at 10mA.
With a power dissipation rating of 500mW at 25°C ambient, the MMSZ5244B is suitable for general-purpose voltage clamping, overvoltage protection, and bias circuits in consumer electronics, portable devices, and industrial controls. It operates over a wide temperature range from -55°C to 150°C, accommodating harsh environments.
The device is housed in a surface mount SOD-123 package, offering a compact footprint for space-constrained designs. It is rated for Moisture Sensitivity Level 1 (unlimited floor life) and is RoHS3 and REACH unaffected compliant, though these compliance claims are unverified in the current data.
