1N5245B

The 1N5245B is a Zener diode from On Semiconductor, part of the 1N5221B-1N5252B series. It provides a nominal Zener voltage of 15V with a tolerance of ±5%, making it suitable for voltage regulation and reference applications. The device has a power dissipation rating of 500mW and a derating of 4mW/°C above 50°C, ensuring reliable operation within its thermal limits.\n\nKey electrical characteristics include a maximum impedance of 16Ω at the test current of 8.5mA, and a low reverse leakage current of 0.1µA at 11V. The Zener voltage temperature coefficient is 0.082%/°C, providing stable performance over temperature. The forward voltage is 1.2V at 200mA.\n\nThe 1N5245B is housed in a DO-35 axial lead package (also designated DO-204AH), with through-hole mounting. It operates over a junction temperature range of -65°C to 200°C, making it suitable for a wide range of environments.\n\nThis Zener diode is commonly used in low-power voltage regulation, overvoltage protection, and reference voltage circuits. Its compact DO-35 package allows for easy integration into through-hole designs.
