1N5252B Description

Short technical summary and product information.

The 1N5252B is a 24V Zener diode from onsemi, part of the 1N5221B-1N5252B series. It offers a nominal zener voltage of 24V with ±5% tolerance, ensuring precise voltage regulation. With a power dissipation rating of 500mW at 25°C, it is suitable for low-power voltage reference and clamping applications. The device features a maximum impedance of 33Ω at 5.2mA test current and 600Ω at 0.25mA knee current. Reverse leakage current is 100nA at 18V (or 0.1μA at 17V per datasheet). The operating junction temperature range is -65°C to 200°C. Housed in a DO-35 (DO-204AH) axial lead package, it is designed for through-hole mounting, making it easy to integrate into various circuit designs. Typical applications include voltage regulation, overvoltage protection, and reference voltage generation in consumer, industrial, and automotive electronics.
