1N5250B-T

Single Zener Diodes Overview

The Diodes Incorporated 1N5250B-T is a discontinued epitaxial Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 20 V with a tolerance of ±5%. The device operates within a power dissipation limit of 500 mW and maintains a maximum reverse leakage current of 0.1 µA at the test voltage. Electrical characteristics include a Zener impedance of 25 Ω at the test current of 6.2 mA, and a forward voltage of 1.1 V at 200 mA. The component supports an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Epitaxial construction provides high stability and low noise performance.
• Glass DO-35 axial lead package ensures isolated case connection.
• Lead-free finish compliant with RoHS directives.

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
