Overview
The Microchip Technology 1N4686/TR is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 3.9 V with a tolerance of 5%. The device operates in the DO-7-2 (DO-35) through-hole package and dissipates up to 500 mW. Electrical characteristics include a maximum reverse leakage current of 5 uA, a test current of 50 uA, and a forward voltage of 1.1 V. It supports an operating temperature range from -65°C to +175°C.
Feature Summary
- Provides stable voltage regulation at a nominal 3.9 V level
- Utilizes hermetically sealed glass construction for environmental protection
- Supports high-temperature operation up to +175°C
Applications
- Voltage reference circuits
- Overvoltage protection
- General-purpose voltage regulation
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm packaging configuration. Ensure the procurement channel sources genuine components matching the exact part number specifications. Cross-reference datasheet parameters such as voltage tolerance and thermal ratings prior to integration.
Selection Notes
Select this component when a precise 3.9 V regulation point is required within a through-hole design. Consider the 5% voltage tolerance and 500 mW power dissipation limits relative to circuit load conditions. Verify that the operating environment remains within the specified -65°C to +175°C temperature range for reliable performance.
Part Context
This component belongs to the standard 1N46xx series of Zener diodes manufactured by Microchip Technology. These devices are widely utilized in electronic systems requiring reliable voltage clamping or reference generation. The specific model utilizes a glass-passivated junction housed in a cylindrical axial leaded package suitable for standard PCB mounting techniques.
Replacement Considerations
Consult official substitution lists for compatible equivalents. Generic replacements must match the 3.9 V Zener voltage, 500 mW power rating, and DO-35/DO-7-2 package dimensions.
