1N5247B Description

Short technical summary and product information.

The 1N5247B is a Zener diode from On Semiconductor, part of the 1N5221B–1N5252B series. It offers a nominal Zener voltage of 17V with ±5% tolerance, and a maximum power dissipation of 500mW. The device is designed for voltage regulation and protection applications requiring a stable reference voltage.

 

Electrically, the 1N5247B features a test current of 7.4mA, a maximum impedance of 19Ω at that current, and a reverse leakage current of 100nA at 13V. The forward voltage is 1.2V at 200mA. The operating temperature range spans from -65°C to 200°C, with a derating factor of 4.0mW/°C above 50°C. The temperature coefficient is 0.084%/°C.

 

The diode is housed in a DO-204AH (DO-35) axial lead package, suitable for through-hole mounting. It is intended for use in low-power voltage regulation, clamping, and reference circuits.
