1N4682/TR

Overview

The Microchip Technology 1N4682/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 2.7 V with a standard tolerance of 5%. The device operates in a through-hole DO-35 (DO-204AH) axial-leaded package and supports a maximum power dissipation of 500 mW. It maintains functionality across an extended temperature range from -65°C to +175°C. The component is supplied in a reel packaging format, ensuring compatibility with automated assembly processes.

Feature Summary

• Provides stable voltage regulation over a broad operating current and temperature range
• Utilizes glass axial-leaded construction for reliable performance
• Supports internal metallurgical bond options for enhanced durability

Applications

• Voltage regulation circuits requiring low voltage references
• Protection against voltage transients in sensitive electronics
• Reference voltage sources in measurement instrumentation

Procurement Notes

Verify the specific suffix configuration when ordering to ensure compliance with required screening levels or bonding options. Confirm that the reel packaging aligns with your automated placement equipment specifications. Cross-reference the manufacturer's latest datasheet to validate electrical parameters against your design requirements before finalizing procurement decisions.

Selection Notes

Select this component when a precise 2.7 V reference is needed within a standard axial package. Ensure the circuit design accommodates the 500 mW power dissipation limit under worst-case thermal conditions. Verify that the operating environment remains within the specified -65°C to +175°C range to maintain guaranteed voltage regulation accuracy and reliability standards.

Part Context

This part belongs to the 1N4678 through 1N4717 series of 0.5 W Zener Voltage Regulators manufactured by Microchip Technology. The series offers a wide selection of voltages from 1.8 to 43 volts in standard 5% tolerances. These components are JEDEC registered and utilize a DO-35 glass body for axial-leaded applications, providing a robust solution for general-purpose voltage regulation tasks.

Replacement Considerations

Direct substitutes include other 1N4682 variants from different manufacturers offering identical 2.7 V Zener characteristics. Equivalent parts must match the DO-35 package outline and 500 mW power rating. Verify pinout compatibility and thermal resistance values to ensure seamless integration into existing designs without modifying the PCB layout.
