1N5821-AP

Overview

The MCC 1N5821-AP is a 3 Amp Schottky Barrier Rectifier with a maximum repetitive peak reverse voltage of 30V. It utilizes a DO-201AD axial package and operates within a junction temperature range of -55°C to +125°C. The device features a low forward voltage drop, reaching up to 0.500V at 3.0A, and supports a peak forward surge current of 80A. Typical junction capacitance is 200pF at 4.0V reverse bias.

Feature Summary

• Low forward voltage drop for high efficiency
• High surge current capability
• Epoxy meets UL 94 V-0 flammability rating

Applications

• Switch mode power supplies
• Polarity protection circuits
• Free wheeling diodes in low voltage inverters

Procurement Notes

Verify the specific ordering suffix to confirm packaging type. The AP suffix indicates Ammo Box packing containing 1.2Kpcs per box. Ensure procurement channels are authorized distributors to guarantee genuine parts with full traceability and compliance with MCC quality standards.

Selection Notes

Select this component when a 30V blocking voltage and 3A average forward current are required in an axial through-hole package. Consider the thermal resistance of 28°C/W and derating curves for ambient temperatures exceeding 85°C. Verify compatibility with lead-free manufacturing processes if RoHS compliance is mandatory.

Part Context

This part belongs to the 1N5820 through 1N5822 series of Schottky barrier rectifiers manufactured by Micro Commercial Components. These devices are designed for general-purpose applications requiring fast switching and low conduction losses. The series covers reverse voltages from 20V to 40V while maintaining consistent current ratings.

Replacement Considerations

Cross-reference with other manufacturers' 1N5821 equivalents. Verify that substitute components match the 30V reverse voltage, 3A current rating, and DO-201AD package dimensions. Confirm electrical characteristics such as forward voltage and leakage current align with original specifications.
