Overview
The Microchip Technology 1N4702/TR is a single Zener diode voltage regulator designed for surface-mount applications. It features a nominal Zener voltage of 15 V with a tolerance of 5%. The device operates within a power dissipation rating of 500 mW and maintains a maximum reverse leakage current of 50 nA at the specified test current of 50 uA. It is housed in a DO-213AA (SOD-80) package, supporting an extended operating temperature range from -65°C to +175°C.
Feature Summary
- Provides stable voltage regulation with a 15 V nominal breakdown voltage.
- Engineered for high-temperature reliability across a wide thermal range.
- Utilizes a compact surface-mount package for automated assembly integration.
Applications
- Voltage reference circuits requiring precise potential levels.
- Over-voltage protection stages in sensitive electronic systems.
- Clamping applications in signal processing pathways.
Procurement Notes
Verify the specific suffix designation against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure that the required operating temperature range aligns with the component's rated limits. Confirm compliance requirements such as RoHS status directly with the manufacturer or authorized distributors prior to procurement.
Selection Notes
Select this component when a 15 V regulation point is required in a surface-mount design. Consider the 500 mW power dissipation limit and the 5% voltage tolerance during circuit planning. Evaluate the low leakage current characteristics for high-impedance applications. Compare against through-hole alternatives if board space constraints are not critical.
Part Context
This part belongs to the standard Zener diode family manufactured by Microchip Technology. It serves as a fundamental passive component for maintaining steady voltages in various electronic assemblies. The TR suffix typically indicates reel packaging for high-volume surface-mount production lines.
Replacement Considerations
Consult official cross-reference guides for verified substitutes. Ensure any replacement matches the 15 V Zener voltage, 500 mW power rating, and compatible surface-mount footprint. Verify that alternative components meet the same temperature and electrical performance standards.
