1N4625-1E3

Overview

The Microchip Technology 1N4625-1E3 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 5.1 V with a tolerance of ±5%. The device operates within a power dissipation limit of 500 mW and utilizes a DO-35 axial leaded glass package. Electrical characteristics include a maximum dynamic impedance of 1500 Ω and a reverse leakage current of 5 µA at 3 V. The component supports an operating temperature range from -65 °C to +175 °C and complies with RoHS standards.

Feature Summary

• Provides stable voltage regulation using a 5.1 V Zener breakdown characteristic in a standard DO-35 glass axial package.
• Features internal metallurgical bonding for enhanced structural integrity and reliability under thermal stress.
• Operates across an extended industrial temperature range, supporting high-temperature environments up to 175 °C.

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in sensitive electronic systems
• General-purpose voltage regulation in low-power designs

Procurement Notes

Verify the specific suffix configuration against the required datasheet revision, as ordering codes may vary based on packaging or compliance updates. Confirm that the procurement channel provides original manufacturer documentation to ensure authenticity. Check for any recent Product Change Notifications (PCNs) regarding assembly sites or material composition changes before finalizing orders.

Selection Notes

Select this component when a 5.1 V regulation point is required in a through-hole axial package. Ensure the circuit design accommodates the specified 500 mW power dissipation limit and the 1500 Ω dynamic impedance. Verify that the ±5% voltage tolerance aligns with the system's precision requirements and that the extended temperature range meets the operational environment constraints.

Part Context

This part belongs to the 1N4625 series of 500 mW Zener diodes manufactured by Microchip Technology. The series offers a wide selection of voltage values in standard 5% tolerances. The 1N4625-1E3 variant specifically denotes the RoHS-compliant version of the standard 1N4625-1 device, maintaining identical electrical performance while adhering to environmental restrictions on hazardous substances.

Replacement Considerations

Direct equivalents include the non-RoHS 1N4625-1 and the JAN1N4625D-1 for military-grade specifications. Commercial alternatives such as the 1N4625DE3 are available but require verification of package compatibility and exact parameter matching.
