Overview
The MCC 1N5819-TP is a silicon Schottky barrier rectifier housed in the DO-41 axial package. It provides a maximum average forward rectified current of 1 A and a peak repetitive reverse voltage of 40 V. The device features a low forward voltage drop, with a maximum rating of 0.6 V at 1 A and 25°C. It supports a non-repetitive peak surge current of 30 A under an 8.3 ms half-sine wave condition. The component operates within a junction temperature range of -55°C to 125°C.
Feature Summary
- Guard ring protection structure for enhanced reliability
- Low power loss characteristics suitable for high efficiency applications
- Epoxy material meets UL 94 V-0 flammability ratings
Applications
- Switch mode power supplies
- High frequency DC to DC converters
- Low voltage high frequency inverters
- Free wheeling diodes
- Polarity protection circuits
- Small battery chargers
Procurement Notes
Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors. Counterfeit parts are prevalent; unauthorized sources lack traceability and warranty coverage. Confirm the suffix indicates RoHS compliance. Ensure the specific ordering code matches the required packaging format, such as tape and reel or bulk, before finalizing procurement.
Selection Notes
Select this component for low voltage, high frequency rectification tasks requiring minimal conduction losses. The DO-41 package suits through-hole designs. Compare thermal resistance values against system constraints. Verify that the 40 V reverse voltage rating exceeds circuit peaks. Consider the 1 A continuous current limit for load requirements.
Part Context
This part belongs to the 1N5817 through 1N5819 series of Schottky rectifiers. All variants share identical physical dimensions and thermal characteristics but differ in their peak repetitive reverse voltage ratings. The 1N5819 specifically offers the highest voltage rating within this group at 40 V, while maintaining the same 1 A current capacity.
Replacement Considerations
Cross-reference with other manufacturers offering 1N5819 equivalents in the DO-41 package. Verify that substitute components match the 40 V reverse voltage and 1 A forward current specifications. Check for compatibility with existing PCB footprints and thermal management strategies.
