1EZ33D5-TP

Overview

The 1EZ33D5-TP is a single Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 33 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and operates within a temperature range of -55°C to +150°C junction temperature. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 25.1 V and a maximum Zener impedance of 45 Ohms. The forward voltage is specified as 1.2 V at 200 mA. It utilizes a DO-41 axial through-hole package.

Feature Summary

• Glass passivated junction construction for enhanced environmental stability
• High thermal performance supporting operation up to 150°C junction temperature
• Designed for general-purpose voltage regulation and reference applications

Applications

• Voltage regulation circuits
• Voltage reference sources
• Overvoltage protection stages

Procurement Notes

Verify the specific manufacturer part number against official MCC documentation to ensure authenticity. Confirm RoHS compliance status and REACH registration details prior to integration. Cross-reference datasheet parameters such as Zener impedance and leakage current with design requirements. Ensure the DO-41 package dimensions match the target PCB footprint.

Selection Notes

Select this component when a 33 V regulation point is required in a through-hole design. The 1 W power rating suits moderate current applications compared to lower-power surface mount alternatives. Verify that the 45 Ohm impedance meets the dynamic regulation needs of the circuit. Consider the axial lead form factor for manual assembly or specific mechanical constraints.
