1N5923C

Single Zener Diodes Overview

The Microchip Technology 1N5923C is a glass-encapsulated Zener diode with a nominal voltage of 8.2 V and a 2% tolerance. It operates in the DO-41 axial package, providing a steady-state power dissipation of 1.25 W at 25°C and up to 1.5 W rated average power. The device features a maximum dynamic impedance of 3.5 Ohms at a test current of 45.7 mA and a maximum reverse leakage current of 0.5 µA at 6.5 V. It supports an operating temperature range from -65°C to +175°C.

• High-reliability military screening applications
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' against official datasheets to confirm the 2% tolerance level. Ensure the required screening level matches the intended application environment. Confirm RoHS compliance status if environmental regulations apply, as commercial versions may differ from standard specifications.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation within a tight 2% tolerance is required. The glass hermetic package offers superior thermal resistance compared to plastic alternatives. Consider the 1.5 W power rating and wide temperature range for demanding environments where stability is critical.

Single Zener Diodes Part Context

This part belongs to the 1N5913BG–1N5956BG series of 1.5 Watt Glass Zener Diodes. The series provides voltage regulation across a wide range from 3.3 V to 200 V. The 'G' suffix indicates a glass casing, while the 'C' suffix denotes a 2% voltage tolerance. These devices are JEDEC registered and available with optional military screening.
