Single Diodes datasheet and documents for SDM20U40-7
Single Diodes Overview
The SDM20U40-7 is a surface-mount Schottky barrier diode manufactured by Diodes Incorporated. It features a peak repetitive reverse voltage of 40 V and a forward continuous current rating of 250 mA. The device operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum forward voltage drop of 0.60 V at 200 mA and a typical reverse recovery time of 10 ns. It utilizes an SOD523 package with a power dissipation capacity of 190 mW.
Single Diodes Feature Summary
- Low forward voltage drop for improved efficiency
- Guard ring construction provides transient protection
- Negligible reverse recovery time and low reverse capacitance
- Totally lead-free, fully RoHS compliant, and halogen/antimony free
Single Diodes Applications
- High frequency rectification in consumer electronics
- Power supply circuits requiring fast switching
- DC-DC converter freewheeling applications
Single Diodes Procurement Notes
Verify the specific ordering suffix '-7' corresponds to the 3,000-unit tape and reel packaging configuration. Confirm that the component meets the required environmental standards, including RoHS 3 compliance and the specified 'Green' material definition regarding bromine, chlorine, and antimony content limits.
Single Diodes Selection Notes
Select this component when a compact SOD523 footprint is required alongside a 40 V blocking capability. Ensure the design accommodates the 250 mA continuous current limit and the thermal resistance constraints associated with the small surface-mount package geometry.
Single Diodes Part Context
This part belongs to the SDM20U40 series of ultra-small surface-mount Schottky barrier diodes. It is designed for high-reliability applications and is qualified to JEDEC standards.
