B350Q-13-F

Overview

The B350Q-13-F is a 3.0A surface-mount Schottky barrier rectifier from Diodes Incorporated, designed for automotive applications. It features a 50V repetitive reverse voltage rating and operates within a junction temperature range of -55°C to +150°C. The device utilizes an SMC (DO-214AB) package with lead-free matte tin terminals. Electrical characteristics include a maximum forward voltage drop of 0.70V at 3.0A and a leakage current of 0.5mA at rated voltage and 25°C. It supports a non-repetitive peak forward surge current of 100A.

Procurement Notes

Verify the specific part number B350Q-13-F against official Diodes Incorporated documentation to confirm electrical ratings and package type. Ensure compliance with RoHS directives and AEC-Q101 qualification requirements relevant to your application environment. Confirm that the SMC package dimensions align with your PCB layout specifications before finalizing procurement decisions.

Selection Notes

Select this component when a 3.0A average rectified output current and 50V reverse voltage rating are required. Consider the SMC package for surface-mount assembly needs. Evaluate thermal resistance values if operating near maximum temperature limits. Verify compatibility with low-voltage, high-frequency inverter circuits or polarity protection schemes based on the specified forward voltage and leakage characteristics.

Part Context

This component belongs to the B320Q–B360Q series of surface-mount Schottky barrier rectifiers. The series offers various voltage ratings from 20V to 60V while maintaining a consistent 3.0A current capacity. All variants share similar mechanical and thermal characteristics, differing primarily in their peak repetitive reverse voltage specifications.

Replacement Considerations

Substitute parts must match the 3.0A current rating, 50V reverse voltage, and SMC package footprint. Verify equivalent forward voltage and leakage current specifications to ensure circuit performance remains within acceptable limits.
