Overview
The B140AE-13 is a surface-mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 1 A. The device utilizes the SMA (DO-214AC) package. Key electrical characteristics include a maximum forward voltage drop of 500 mV at 1 A, a maximum reverse leakage current of 200 µA at 40 V, and a junction capacitance of 50 pF at 4 V and 1 MHz. The component operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Schottky barrier construction for low forward voltage drop
- Glass passivated die for enhanced reliability
- Plastic material rated UL 94V-0 for flammability
Applications
- High-frequency rectification in power supplies
- Free-wheeling diodes in DC-DC converters
- Polarity protection circuits
Procurement Notes
Verify the specific ordering suffix matches the required package and tape-and-reel configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component meets the thermal management requirements for the intended operating environment. Cross-reference the datasheet revision date to guarantee parameter accuracy against current production batches.
Selection Notes
Select this component when a low forward voltage drop is critical for efficiency in low-voltage applications. The 1 A current rating suits moderate power levels where SMA packaging constraints apply. Consider the 40 V reverse voltage limit for input protection or rectification tasks. Evaluate the thermal performance relative to the expected ambient conditions and heat dissipation capabilities of the PCB layout.
Part Context
This part belongs to the B1xxAE series of Schottky rectifiers from Diodes Incorporated. The series offers various voltage ratings including 20 V, 30 V, and 40 V options. These devices are designed for general-purpose high-efficiency rectification in consumer electronics and industrial equipment requiring reliable surface-mount solutions.
Replacement Considerations
Compatible substitutes within the same family include the B120AE-13 and B130AE-13, which share identical packaging and current ratings but differ in reverse voltage specifications.
