1EZ140D5-TP

Overview

The 1EZ140D5-TP is a silicon planar power Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 140 V with a maximum power dissipation of 200 mW. The component utilizes the 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 complies with RoHS3 standards.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Designed in a low-profile axial leaded package
• Capable of operation across an extended industrial temperature range

Applications

• Voltage reference circuits requiring stable high-voltage biasing
• Overvoltage protection stages in electronic systems
• Clamping applications in signal conditioning paths

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as -HF may indicate halogen-free compliance. Confirm the package type matches the target PCB footprint requirements. Ensure the thermal management design accommodates the specified power dissipation limits under all operating conditions.

Selection Notes

Select this component when a precise 140 V regulation point is required in a through-hole assembly. The DO-41 package offers robust mechanical stability for manual or automated insertion processes. Consider the ±5% tolerance for circuit precision requirements before finalizing the design integration.
