1N4627C-1/TR

Overview

The Microchip Technology 1N4627C-1/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 6.2 V with a tolerance of ±5%. The device operates in the DO-35-2 axial through-hole package and dissipates up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 1200 Ω, tested at 250 µA. It supports an operating temperature range from -65 °C to +175 °C.

Feature Summary

• Provides stable voltage regulation via Zener breakdown mechanism
• Capable of handling high thermal stress within extended temperature ranges
• Designed for reliable performance in harsh environmental conditions

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in sensitive electronic systems
• Clamping applications for signal line stabilization

Procurement Notes

Verify that the suffix /TR indicates tape-and-reel packaging rather than bulk or tray formats. Confirm compliance status as these parts often lack standard RoHS certification due to military-grade specifications. Ensure the specific lot traceability meets project requirements before finalizing orders.

Selection Notes

Select this component when a 6.2 V reference is required in an axial leaded package. Consider the 1200 Ω impedance for low-current applications where higher dynamic resistance is acceptable. Verify that the ±5% tolerance aligns with circuit precision needs compared to tighter tolerance alternatives.

Part Context

This part belongs to the 1N4627 series of Zener diodes manufactured by Microchip Technology. It shares electrical similarities with other variants in the family but differs in packaging and specific qualification levels. The C-1 designation typically denotes specific manufacturing standards or testing criteria defined by the original MIL-SPEC lineage.

Replacement Considerations

Direct substitutes include JAN1N4627C-1 and JANTX1N4627-1. These equivalents maintain similar electrical parameters and package dimensions. Verify pinout compatibility and thermal dissipation capabilities before swapping components in existing designs.
