Overview
The BD244B-S is a PNP silicon power transistor manufactured by Bourns Inc., housed in a TO-220 plastic package. It features a maximum collector-emitter voltage of 80V and a continuous collector current rating of 6A. The device is designed for high-power applications, with safe operating area limitations defined by average junction temperature and second breakdown characteristics. Thermal derating is specified at 16 mW/°C above 150°C free air temperature.
Feature Summary
- PNP silicon power transistor configuration
- TO-220 plastic package housing
- High current handling capability up to 6A
Applications
- Power switching circuits
- Linear power regulation
- General-purpose amplification
Procurement Notes
Verify the specific suffix 'S' against official Bourns documentation to confirm exact electrical tolerances and marking codes. Confirm availability status as some listings indicate obsolete status. Ensure the TO-220 package type matches thermal requirements. Cross-reference datasheet parameters for collector current and voltage ratings before integration.
Selection Notes
Select this component for applications requiring PNP power switching or linear operation within an 80V collector-emitter voltage limit. Consider the 6A continuous current rating and TO-220 thermal performance. Evaluate safe operating area curves for second breakdown protection. Ensure heat sinking meets the 16 mW/°C derating requirement above 150°C ambient temperature.
Part Context
The BD244B-S belongs to a family of complementary silicon power transistors, often paired with NPN variants like the BD243 series. These components are standard discrete power devices used in industrial and consumer electronics. The TO-220 package provides robust mechanical stability and thermal dissipation for medium-to-high power applications.
Replacement Considerations
Complementary NPN equivalents include the BD243B. Direct pin-compatible replacements may exist from other manufacturers producing standard PNP power transistors with similar 80V/6A ratings in TO-220 packages. Verify all electrical parameters match before substitution.
