1EZ190D5-TP

Overview

The 1EZ190D5-TP is a 1-watt silicon Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 190 volts with a tolerance of ±5%. The device utilizes a DO-41 axial leaded package and supports an operating junction temperature range from -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 500 nA at 14.4 V and a forward voltage of 1.2 V at 200 mA. The component is RoHS compliant and designed for through-hole mounting applications.

Feature Summary

• Provides stable voltage regulation within a 5% tolerance band
• Features glass passivated junction for enhanced reliability
• Supports high-temperature operation up to 150°C

Applications

• Voltage reference circuits
• Over-voltage protection
• Clamping applications in power supplies

Procurement Notes

Verify the specific suffix requirements against the official datasheet before ordering, as variations may exist. Confirm that the DO-41 package dimensions align with your PCB layout constraints. Ensure that the 1W power rating is sufficient for your thermal management design under continuous operation conditions.

Selection Notes

Select this component when a 190V Zener voltage is required in a standard axial package. Consider the 500 nA leakage specification for low-current circuit designs. Verify that the 1W power dissipation capability meets the peak pulse and continuous load requirements of the target application environment.

Part Context

This part belongs to the MCC 1EZ series of 1-watt Zener diodes. The series offers various voltage options ranging from 5.6V to 39V in some contexts, but this specific model targets higher voltage regulation needs. The DO-41 package is a standard industry form factor for general-purpose through-hole diodes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing should be performed using the exact voltage, power rating, and package specifications.
