Overview
The MCC 1N5819-BP is a 40 V, 1 A axial power Schottky rectifier housed in the DO-41 package. It features a maximum repetitive reverse voltage of 40 V and an average forward current rating of 1 A. The device exhibits a low forward voltage drop with a maximum value of 0.6 V at 1 A and 25°C. Reverse leakage current is specified at a maximum of 10 mA at rated voltage and 25°C, increasing to 50 mA at 100°C. Thermal resistance from junction to ambient is 75 °C/W, supporting operation within a junction temperature range of -55°C to 125°C.
Feature Summary
- Guard ring protection structure for enhanced reliability
- Epoxy material meets UL 94 V-0 flammability rating
- Lead-free finish compliant with RoHS standards
Applications
- Switch mode power supplies
- High frequency DC to DC converters
- Low voltage high frequency inverters
- Free wheeling diodes
- 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 -BP suffix indicates bulk packaging containing 1,000 pieces per box. Ensure compliance with specific halogen-free requirements if applicable by checking for the -HF suffix designation.
Selection Notes
Select this component for applications requiring low conduction losses and negligible switching losses. The DO-41 through-hole package suits standard PCB layouts. Verify thermal management capabilities against the 75 °C/W junction-to-ambient resistance. Consider the 40 V reverse voltage limit for circuit design margins. Evaluate surge current ratings for transient protection needs.
Part Context
This part belongs to the 1N581x series of Schottky barrier rectifiers manufactured by Micro Commercial Components. The series includes variants with different reverse voltage ratings such as 1N5817 (20 V) and 1N5818 (30 V). All share similar physical dimensions and electrical characteristics except for the blocking voltage specification.
Replacement Considerations
Cross-reference with other manufacturers offering 1N5819 equivalents in DO-41 packages. Verify pinout compatibility and thermal resistance values. Check for identical forward voltage and reverse leakage specifications to ensure circuit performance parity.
