1EZ250D5-TP

Overview

The 1EZ250D5-TP is a Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 250 V and a maximum power dissipation of 1 W. The device utilizes a DO-41 axial through-hole package with a ±5% tolerance. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 200 V and a maximum dynamic impedance of 300 Ω. The component operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Provides stable voltage regulation in the high-voltage range via Zener breakdown mechanism.
• Constructed with silicon material for reliable performance across wide temperature extremes.
• Designed for through-hole mounting using an axial leaded configuration.

Applications

• High-voltage reference circuits requiring precise potential levels.
• Overvoltage protection stages for sensitive electronic loads.
• Clamping applications in power supply output stages.

Procurement Notes

Verify the specific datasheet version for the 1EZ250D5-TP, as official documentation may vary between distributors. Confirm that the DO-41 package dimensions match your PCB footprint requirements. Ensure the 1 W power rating aligns with your thermal management design under continuous operating conditions. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a 250 V regulation point is required in a through-hole assembly. The 1 W power rating supports moderate current handling compared to lower-power surface mount alternatives. Consider the DO-41 package size constraints during layout planning. Evaluate the 300 Ω dynamic impedance against the noise sensitivity of your target application circuit.

Part Context
