The MMSZ5242ET1G is a 12V Zener diode from On Semiconductor's MMSZ52xxET1G series, offering a nominal zener voltage of 12V with ±5% tolerance. Rated for 500mW continuous power dissipation on FR-4 or FR-5 boards, it provides reliable voltage regulation and protection in low-power circuits. The device features a maximum zener impedance of 30Ω, typical forward voltage of 900mV at 10mA, and reverse leakage current of 1µA at 9.1V. It also includes enhanced ESD protection with a Class 3 rating (>16kV Human Body Model) and can handle 225W peak power for transient suppression during an 8x20µs pulse.
The MMSZ5242ET1G is housed in a surface-mount SOD-123 package, designed for automated assembly and high-density applications. The package features a corrosion-resistant lead finish and is rated UL 94 V-0 for flammability. It supports operating temperatures from -55°C to 150°C, with a maximum soldering temperature of 260°C for 10 seconds. The part is available in tape and reel packaging with a standard quantity of 3000 units.
Applications include voltage regulation, overvoltage clamping, and reference voltage generation in consumer electronics, industrial controls, and automotive systems (with companion SZ series qualified to AEC-Q101). The Pb-free finish (suffix G) ensures RoHS compliance, making it suitable for environmentally sensitive designs.
