B320AE-13

Overview

The B320AE-13 is a 3.0A Schottky barrier rectifier from Diodes Incorporated, housed in an SMA case. It features a maximum repetitive reverse voltage (VRRM) of 20V and a forward voltage drop (VF) of 0.50V max at +25°C with 3A forward current. The device exhibits a maximum reverse leakage current (IR) of 0.10mA at 20V and +25°C. It supports an average rectified output current of 3A and a non-repetitive peak forward surge current of 80A. Operating and storage temperatures range from -55°C to +150°C.

Feature Summary

• Provides low forward voltage drop for improved efficiency and cooler operation
• Offers reduced high-temperature reverse leakage to increase reliability against thermal runaway
• Constructed with lead-free finish and RoHS compliant materials
• Utilizes halogen and antimony free green molding compound

Applications

• Boost diode circuits
• Blocking diode applications
• Recirculating diode implementations

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration. Confirm that the component meets all applicable RoHS directives and environmental standards relevant to your region. Ensure the SMA package dimensions align with your PCB footprint requirements. Check for any automotive qualification requirements if the application demands AEC-Q100 compliance or IATF 16949 manufacturing certification. Validate date code markings for traceability purposes.

Selection Notes

Select this component when a low forward voltage drop is critical for system efficiency. Consider the 20V reverse voltage rating to ensure adequate headroom for the specific circuit design. Evaluate the thermal resistance characteristics for heat dissipation needs in the intended environment. Verify compatibility with surface mount assembly processes given the SMA package type. Assess the operating temperature range against the expected ambient conditions of the final application.

Part Context

This part belongs to the B320AE/B340AE series of Schottky barrier rectifiers manufactured by Diodes Incorporated. The series shares similar mechanical and electrical characteristics, differing primarily in their maximum repetitive reverse voltage ratings. The B320AE specifically denotes the 20V variant within this family, designed for general rectification tasks requiring fast switching and low loss.

Replacement Considerations

Consult official manufacturer substitution guides for verified equivalent parts. Ensure any replacement maintains the SMA package outline and pinout configuration. Verify that alternative components meet or exceed the 3A current rating and 20V reverse voltage specifications. Confirm compatibility with existing thermal management strategies and PCB layout constraints.
