BD245-S

Overview

The BD245-S is an NPN silicon power transistor manufactured by Bourns Inc. It features a maximum collector-emitter voltage of 80 V and a continuous collector current rating of 10 A. The device is housed in a flange mount package with three terminals, where the case is electrically connected to the collector. It supports a peak collector current of 15 A and operates at a maximum junction temperature of 150 °C. Designed for complementary use with the BD246 series, it offers a minimum DC current gain (hFE) of 4.

Feature Summary

High current handling capability with 10 A continuous and 15 A peak collector current ratings
Robust thermal management through a flange mount package design
Complementary pairing capability with the BD246 series PNP transistors

Applications

Power amplifier circuits
Switching applications requiring high current drive
Complementary push-pull output stages

Procurement Notes

Verify the specific manufacturer source, as BD245 variants are produced by multiple vendors including Power Innovations Ltd and Savantic. Confirm that the Bourns Inc. version matches the required electrical parameters, particularly the 80V rating and 10A current capacity. Ensure the flange mount package type aligns with your thermal dissipation requirements and mounting constraints before finalizing procurement.

Selection Notes

Select this component when designing circuits that require an NPN power transistor with an 80V breakdown voltage and substantial current handling. The flange mount package is suitable for applications needing direct heatsinking. Consider the complementary BD246 series if a matched pair is required for balanced performance in push-pull configurations. Verify the minimum hFE of 4 meets your base drive requirements.

Part Context

The BD245-S belongs to the family of NPN silicon power transistors designed for general-purpose power switching and amplification. These devices are characterized by their rugged construction and ability to handle significant power dissipation when mounted on appropriate heat sinks. The flange mount style distinguishes them from standard leaded packages, offering improved thermal transfer capabilities for high-power applications.
