Overview
The Microchip Technology 1N4626D/TR is a Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 5.6 V with a tight tolerance of 2%. The device operates in a surface-mount DO-213AA (SOD-80) package and dissipates up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 1.4 kΩ at a test current of 250 µA. It supports an extended operating temperature range from -65°C to +175°C.
Feature Summary
- Provides precise voltage regulation with a 2% tolerance on the 5.6 V breakdown voltage.
- Engineered for high-temperature reliability, supporting operation up to +175°C.
- Utilizes a compact surface-mount DO-213AA package for automated assembly.
Applications
- Precision voltage reference circuits
- Over-voltage protection stages
- Temperature-compensated bias networks
Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm that the 2% voltage tolerance meets strict circuit requirements. Ensure the selected component matches the DO-213AA footprint dimensions for PCB layout compatibility. Validate that the 500 mW power dissipation rating is sufficient for the intended thermal environment.
Selection Notes
Select this component when a stable 5.6 V reference is required in space-constrained designs. The low leakage current makes it suitable for high-impedance inputs. Consider the 1.4 kΩ impedance if signal integrity at the test current is critical. The wide temperature range allows deployment in harsh industrial or automotive environments without derating concerns.
Part Context
This part belongs to the standard 1N4626 series of Zener diodes manufactured by Microchip Technology. It serves as the surface-mount equivalent to through-hole variants like the JAN1N4626D-1. The series is widely used in general-purpose electronics requiring reliable voltage clamping and regulation.
Replacement Considerations
Cross-reference with JAN1N4626D-1 for through-hole compatibility. Verify pinout and package dimensions against other SOD-80 devices before substitution.
