1N1341B

Single Diodes Overview

The Microchip Technology 1N1341B is a standard recovery rectifier diode designed for high-current applications. It features a maximum DC reverse voltage (Vr) of 50 V and an average rectified current (Io) of 16 A. The device utilizes a DO-4 (DO-203AA) axial leaded package with stud mounting capabilities. Key electrical characteristics include a forward voltage (Vf) of 1.3 V at 30 A and a reverse leakage current of 10 µA at 50 V. It operates within a junction temperature range of -65°C to +200°C and belongs to the S/R20 series.

Single Diodes Feature Summary

• High thermal stability with a junction temperature rating up to 200°C
• Robust mechanical construction suitable for stud mounting in the DO-4 package
• Standard recovery speed optimized for general-purpose rectification

Single Diodes Applications

• Industrial power supply rectification
• Battery charging circuits
• Welding equipment power stages

Single Diodes Procurement Notes

Verify RoHS compliance status prior to integration, as this component is explicitly listed as non-compliant with RoHS directives. Confirm that the DO-4 stud mount interface matches the target heatsink or chassis design. Ensure the 50 V reverse voltage rating provides adequate margin for the specific circuit's peak inverse voltage requirements. Validate that the 16 A average current capacity aligns with the thermal management strategy of the final assembly.

Single Diodes Selection Notes

Select this component when high surge current handling and wide operating temperature ranges are required. The DO-4 package facilitates direct mounting to cold plates or chassis for efficient heat dissipation. Consider the 1.3 V forward voltage drop for efficiency calculations in low-voltage, high-current paths. Verify that the standard recovery time meets the switching frequency constraints of the application without excessive reverse recovery losses.

Single Diodes Part Context

The 1N1341B is part of the Microchip S/R20 series of axial leaded rectifiers. This series is engineered for rugged environments requiring reliable performance under high thermal stress. The DO-4 package variant specifically supports stud mounting, distinguishing it from standard through-hole axial components. It serves as a discrete solution for power conversion tasks where integrated modules are unsuitable due to size or mounting constraints.

Single Diodes Replacement Considerations

Cross-reference with other 1N1341 variants or equivalent 50 V, 16 A stud-mount diodes from other manufacturers. Verify pinout compatibility and physical dimensions of the DO-4 package before substitution. Ensure that any replacement maintains the same junction temperature rating and reverse leakage specifications.
