## Description

The ONSEMI 1N5234B is a 500 mW single Zener diode housed in a hermetically sealed glass DO-35 axial lead package. Engineered for reliable voltage regulation and reference applications, this 2-pin through-hole component features a nominal Zener voltage ($V_Z$) of 6.2 V at a test current ($I_Z$) of 20 mA, with a tight operational tolerance and a maximum dynamic impedance ($Z_Z$) of 7 $\Omega$. It supports an operating and storage temperature range from -65 °C up to a maximum junction temperature of 200 °C, backed by a power dissipation rating of 500 mW that derates linearly above 50 °C by 4.0 mW/°C.

Designed for consistent performance in precision analog circuits, the 1N5234B exhibits a maximum reverse leakage current ($I_R$) of 5.0 $\mu$A at a reverse test voltage ($V_R$) of 4.0 V, and provides a maximum forward voltage ($V_F$) of 1.2 V at a forward current ($I_F$) of 200 mA. The robust DO-204AH (DO-35) glass construction ensures high mechanical stability and environmental protection, making it well-suited for demanding industrial and consumer electronics environments.

This Zener diode is typically utilized in voltage reference networks, linear power supply regulators, overvoltage protection circuits, and signal clipping applications. Its stable 6.2 V breakdown characteristic assists in establishing fixed reference rails for operational amplifiers, analog-to-digital converters (ADCs), and microcontrollers where tight voltage constraints and dependable thermal coefficients are critical for system accuracy.
