Overview
The MCC 1N5391-BP is a silicon rectifier diode in the 1N5391 through 1N5399 series, rated for 1.5 Amps average forward current and 50 Volts maximum repetitive peak reverse voltage. It utilizes a DO-15 axial leaded package with epoxy meeting UL 94 V-0 flammability ratings. The device supports an operating junction temperature range from -55°C to +150°C and features low leakage current characteristics. Electrical specifications include a maximum DC reverse current of 5.0μA at rated blocking voltage and a typical thermal resistance of 26°C/W from junction to lead.
Feature Summary
- High current capability with 1.5 Amp average forward rectified current rating
- Low instantaneous forward voltage drop for efficient power conversion
- Robust construction with UL 94 V-0 flame retardant epoxy encapsulation
- Extended thermal performance supporting operation up to +150°C junction temperature
Applications
- General-purpose rectification in power supply circuits
- AC to DC conversion stages
- Polarity protection applications
- Free-wheeling diodes in inductive load circuits
Procurement Notes
Verify the specific ordering suffix to confirm packaging configuration, as the BP designation indicates bulk packing. Ensure compliance requirements such as RoHS status are confirmed against the latest manufacturer documentation before procurement. Cross-reference the part number with authorized distributors to guarantee genuine components and full traceability. Confirm that the selected packaging meets the assembly line handling requirements for the intended production volume.
Selection Notes
Select this component when a standard recovery rectifier with 1.5A capacity and 50V reverse voltage rating is required. Consider the DO-15 package dimensions for PCB layout constraints and verify thermal management needs based on the 26°C/W junction-to-lead thermal resistance. Evaluate the forward voltage drop characteristics against system efficiency targets. Ensure the operating environment stays within the specified -55°C to +150°C junction temperature range for reliable long-term performance.
Part Context
This device belongs to the 1N5391 through 1N5399 series of 1.5 Amp silicon rectifiers manufactured by Micro Commercial Components. The series covers voltage ratings from 50V to 1000V, providing options for various DC blocking voltage requirements while maintaining consistent current handling capabilities. These diodes are designed for general-purpose applications requiring reliable rectification in compact axial packages.
Replacement Considerations
Direct replacements must match the 1.5A current rating, 50V reverse voltage, and DO-15 package form factor. Verify equivalent electrical parameters including forward voltage drop and reverse leakage current. Check for compatible thermal resistance values to ensure similar heat dissipation performance. Confirm that any substitute part meets the same safety and environmental certifications.
