1EZ9.1D5-TP

Overview

The MCC 1EZ9.1D5-TP is a 1.0 W silicon Zener diode designed for voltage regulation and protection applications. It features a nominal Zener voltage of 9.1 V with a tolerance of ±5%. The device utilizes a glass-passivated junction to ensure reliability and operates within a temperature range of -55°C to +150°C. Packaged in the DO-41 axial leaded format, it offers excellent clamping capability and low profile characteristics suitable for through-hole mounting.

Feature Summary

• Glass passivated junction for enhanced stability
• Excellent clamping capability for transient protection
• Halogen-free construction available upon request

Applications

• Voltage regulation circuits
• Transient voltage suppression
• Reference voltage sources

Procurement Notes

Verify component authenticity by checking for the cathode band marking and type number on the package body. Confirm compliance status via RoHS and REACH documentation provided by Micro Commercial Components. Ensure the ordering suffix matches the required halogen-free specification if applicable. Cross-reference datasheet parameters against specific circuit requirements before integration.

Selection Notes

Select this component when a 9.1 V reference or clamp is needed in an axial package. The DO-41 form factor supports through-hole assembly processes. Consider the 1 W power dissipation rating relative to ambient temperature derating curves. Verify that the ±5% voltage tolerance meets the precision requirements of the target application design.
