1N5222B

Single Zener Diodes Overview

The onsemi 1N5222B is a single silicon planar Zener diode housed in an axial lead DO-35 glass package. It provides a nominal Zener voltage of 2.5 V with a ±5% tolerance, measured at a test current of 20 mA. The device supports a maximum power dissipation of 500 mW and maintains a low Zener impedance of 30 Ω under these conditions. It operates within a junction temperature range of −65°C to +200°C and features a typical voltage temperature coefficient of −0.085%/°C.
