B170-13-F

Overview

The B170-13-F is a Schottky barrier rectifier manufactured by Diodes Incorporated, designed for surface-mount applications in the SMA (DO-214AC) package. It features a single diode configuration with silicon technology. Key electrical parameters include a maximum repetitive peak reverse voltage of 70 V and an average forward rectified current of 1 A. The device exhibits a typical forward voltage of 0.79 V at 1 A and a maximum reverse leakage current of 500 uA. It supports a forward surge current of 30 A and operates within a junction temperature range of -65 °C to +150 °C.

Feature Summary

• Utilizes Schottky barrier technology for low forward voltage drop and high switching efficiency
• Engineered for surface-mount installation using the compact SMA package
• Capable of handling high reverse voltages up to 70 V with robust thermal stability

Applications

• General-purpose rectification in power supply circuits
• Protection against polarity reversal in DC systems
• Freewheeling diodes in inductive load switching applications

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as Diodes Incorporated may offer different tape-and-reel options or lead-free specifications under similar part numbers. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the procurement channel provides valid traceability for the component batch to maintain quality standards in production environments.

Selection Notes

Select this component when a low-cost, high-current Schottky rectifier is needed for 70 V reverse voltage applications. The SMA package suits space-constrained designs requiring 1 A continuous current. Compare forward voltage characteristics against alternative brands to ensure compatibility with system efficiency targets. Verify that the operating temperature range meets the environmental requirements of the final assembly.

Part Context

This component belongs to the B170 series of high-voltage Schottky barrier rectifiers from Diodes Incorporated. The series includes variants with different voltage ratings, such as B180 and B190, sharing similar physical footprints and current capabilities. These devices are commonly used in consumer electronics and industrial equipment where efficient power conversion and compact form factors are prioritized over ultra-low leakage performance.

Replacement Considerations

Direct substitutes include other 1 A, 70 V Schottky diodes in the SMA package, such as those from Vishay or ON Semiconductor. Ensure replacement parts match the forward voltage and reverse leakage specifications to maintain circuit performance. Verify pinout compatibility and thermal resistance values before swapping components in existing designs.
