Overview
The Microchip Technology 1N5806 is a fast recovery rectifier designed for surface mount applications. It features a reverse voltage rating of 150 V and an average forward current capacity of 2.5 A. The device utilizes a D-5A (SQ-MELF) package, providing a compact form factor with low thermal resistance. Key electrical parameters include a maximum forward voltage of 975 mV at 2.5 A and a rapid reverse recovery time of 25 ns. It supports a maximum surge current of 35 A and operates within a junction temperature range of -65 °C to +175 °C.
Feature Summary
- Fast recovery performance suitable for high-frequency switching applications
- Low leakage current characteristics for improved efficiency
- Hermetic surface mount packaging for harsh environment reliability
Applications
- Secondary ultrafast rectification in switch-mode power supplies
- Free-wheeling diode circuits in DC-to-DC converters
- Reverse polarity protection systems
Procurement Notes
Verify the specific suffix (e.g., US, USe3/TR) to confirm package type and lead-free status. Confirm RoHS compliance requirements against the specific ordering code. Ensure the selected variant matches the required mounting style and thermal management needs for the target design.
Selection Notes
Select this component for designs requiring fast recovery times and high-temperature operation up to 175 °C. The D-5A package offers a standard footprint compatible with industry-referenced layouts. Consider the 150 V reverse voltage rating when designing for low-voltage conversion stages.
Part Context
This part belongs to the 1N58xx series of ultrafast rectifiers manufactured by Microchip Technology. It is characterized by planar technology and is often qualified for radiation-hardened or space-grade applications depending on the specific suffix. The series provides robust performance in compact surface-mount packages.
Replacement Considerations
Check datasheets for equivalent parts from other manufacturers offering similar 150 V, 2.5 A specifications. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement meets the same reverse recovery time and leakage current requirements.
