Overview
The MCC 1N5821-BP is a 3.0 Amp Schottky Barrier Rectifier with a maximum repetitive peak reverse voltage of 30 Volts. It utilizes the DO-201AD axial package and operates within a junction temperature range of -55°C to +125°C. The device features a maximum instantaneous forward voltage of 0.500V at 3.0A and supports an 80A peak forward surge current. Electrical characteristics include a typical junction capacitance of 200pF and a maximum thermal resistance of 28°C/W.
Feature Summary
- Low forward voltage drop combined with high current capability for efficient power conversion
- High surge current capability suitable for transient load conditions
- Epoxy material meets UL 94 V-0 flammability rating for safety compliance
Applications
- Switch mode power supplies
- Free wheeling diodes in inductive circuits
- Polarity protection applications
- Small battery chargers
Procurement Notes
Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm the BP suffix indicates bulk packaging containing 500 pieces per box. Ensure RoHS compliance requirements are met, as the P suffix designates compliant status. Request Halogen-free versions using the HF suffix if necessary for specific environmental regulations.
Selection Notes
Select this component when a 30V blocking voltage and 3A continuous current rating are required. The DO-201AD through-hole package suits standard PCB mounting. Consider the low forward voltage for efficiency in low-voltage rectification. Verify thermal management needs against the 28°C/W junction-to-ambient resistance for high-temperature environments.
Part Context
This part belongs to the 1N5820 through 1N5822 series of Schottky barrier rectifiers manufactured by Micro Commercial Components. The series covers voltage ratings from 20V to 40V while maintaining a consistent 3.0 Ampere current capacity across all variants. The 1N5821 specifically targets 30V applications within this standardized product line.
Replacement Considerations
Compatible substitutes include the 1N5821RLG from onsemi. Verify pinout compatibility and electrical parameters match the original specifications before implementation.
