1EZ20D5-TP

Overview

The 1EZ20D5-TP is a Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 20 V with a power dissipation rating of 1 W. The device utilizes the DO-41 axial through-hole package and maintains a tolerance of ±5%. Electrical characteristics include a maximum reverse leakage current of 500 nA at 15.2 V and a maximum impedance of 30 Ohms. The component supports an operating junction temperature range from -55°C to 150°C.

Feature Summary

• Provides stable voltage regulation in the 1 W power class for circuit protection applications.
• Constructed in a robust DO-41 axial leaded package suitable for through-hole mounting.
• Operates reliably across a wide industrial temperature range up to 150°C.

Applications

• Voltage reference circuits requiring precise 20 V levels.
• Overvoltage protection stages in power supply inputs.
• Clamping applications in signal conditioning paths.

Procurement Notes

Verify the specific datasheet version before integration, as manufacturing parameters may evolve. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the DO-41 footprint matches the target PCB layout. Cross-reference the exact part number suffix to confirm the standard tape-and-reel or bulk packaging availability for the required production volume.

Selection Notes

Select this component when a 1 W axial Zener diode is required for moderate current regulation tasks. The DO-41 package offers superior thermal handling compared to smaller surface-mount alternatives. Consider the ±5% tolerance for applications demanding tighter voltage accuracy. Evaluate the 30 Ohm impedance for high-frequency noise sensitivity requirements in the design.

Part Context

This component belongs to the MCC 1EZ series of general-purpose Zener diodes. The series provides various voltage options within the 1 W power dissipation category. These devices are designed for reliable performance in consumer electronics and industrial control systems where cost-effective voltage regulation is necessary.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with generic DO-41 1W 20V Zener diodes from other manufacturers based on electrical specifications.
