The 1N5349B is a 12V Zener diode from On Semiconductor, part of the 1N53 series of 5W Surmetic 40 voltage regulators. It features a reverse Zener voltage of 12V with ±5% tolerance and a maximum power dissipation of 5W at 25°C lead temperature. The device offers a low maximum Zener impedance of 2.5Ω at the test current and a maximum forward voltage of 1.2V at 1A. It is designed for through-hole mounting in a T-18 axial lead plastic package.
This Zener diode provides robust surge protection with a surge power rating of 180W for 8.3ms and an ESD rating of Class 3 (>16kV) per the Human Body Model. It operates over a wide temperature range from -65°C to 200°C junction temperature, with a thermal resistance of 25°C/W from junction to lead. The device is suitable for voltage regulation, clamping, and protection circuits in various electronic applications.
