1EZ27D5-TP

Overview

The 1EZ27D5-TP is a Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 27 V with a power dissipation rating of 1 W. The device utilizes a DO-41 axial through-hole package and maintains a tolerance of ±5%. It operates within a junction temperature range of -55°C to 150°C and exhibits a maximum reverse leakage current of 5 µA at 25.1 V.

Feature Summary

• Provides stable voltage regulation via Zener breakdown characteristics in the 1 W power class.
• Features low reverse leakage current for efficient operation in high-impedance circuits.
• Constructed with a hermetically sealed glass DO-41 axial package for robust surface mounting.

Applications

• Voltage reference circuits requiring precise potential levels.
• Overvoltage protection stages in electronic systems.
• Clamping applications for transient voltage suppression.

Procurement Notes
