The MMSZ18T1G is a 18V Zener diode from ON Semiconductor, part of the MMSZxxxT1G series of Zener voltage regulators. It is designed for voltage regulation and protection applications requiring a nominal 18V with ±5% tolerance. The device can dissipate up to 500mW of power on standard FR-4 or FR-5 boards, making it suitable for moderate power applications.
Key electrical characteristics include a maximum forward voltage of 900mV at 10mA, a reverse leakage current of 50nA at 12.6V, and a maximum Zener impedance of 45Ω at the test current. The operating temperature range spans -55°C to 150°C, with thermal resistance of 340°C/W junction-to-ambient and 150°C/W junction-to-lead.
The MMSZ18T1G is housed in a surface mount SOD-123 package, which is void-free, transfer-molded thermosetting plastic with a corrosion-resistant finish. It is supplied in tape and reel packaging with 3000 units per reel. The device is Pb-Free and has an ESD rating of Class 3 (>16kV) per the Human Body Model. The package is UL 94 V-0 rated for flammability.
