1N5357B Description

Short technical summary and product information.

The 1N5357B is a 20V Zener diode from onsemi, part of the 1N53 series of 5W Surmetic 40 voltage regulators. It features a nominal Zener voltage of 20V with ±5% tolerance, capable of dissipating up to 5W of power. The device offers a maximum Zener impedance of 3Ω at the test current, and a reverse leakage current of only 500nA at 15.2V. It is designed for through-hole mounting in a T-18 axial package, with a cathode band indicating polarity. The operating temperature range spans -65°C to 200°C, making it suitable for a wide variety of environments. The 1N5357B includes ESD protection rated at Class 3 (>16kV) per Human Body Model and can handle surge power up to 180W for 8.3ms. This diode is ideal for voltage regulation applications in power supplies, industrial equipment, and consumer electronics.
