2SB1131S-AE

Single Bipolar Transistors Overview

The 2SB1131S-AE is a PNP bipolar junction transistor manufactured by onsemi. It features a collector-emitter breakdown voltage of 20V and a maximum continuous collector current of 5A. The device is housed in a TO-92VAR package, which is a through-hole configuration. Key electrical parameters include a minimum DC current gain (hFE) of 100 and a maximum power dissipation of 1W. The component supports operating temperatures up to 150°C and is designed for general switching applications requiring low saturation voltage.

Single Bipolar Transistors Feature Summary

• PNP polarity with high current handling capability
• Low collector-to-emitter saturation voltage for efficient switching
• Fast switching speed suitable for high-frequency inverters

Single Bipolar Transistors Applications

• Relay drivers
• High-speed inverters
• DC-DC converters
• General high-current switching circuits

Single Bipolar Transistors Procurement Notes

Verify the specific suffix AE against official onsemi documentation to confirm pinout and packaging details. Ensure the procurement source provides valid datasheets matching the 20V/5A specifications. Cross-reference the manufacturer part number to avoid confusion with similar variants like the standard 2SB1131 without the AE suffix.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring a robust PNP switch with moderate voltage ratings. The 5A current capacity and low VCE(sat) make it suitable for driving loads directly or interfacing with logic circuits. Consider thermal management due to the 1W power dissipation limit in the TO-92VAR package.

Single Bipolar Transistors Part Context

This transistor belongs to onsemi's family of high-current, low-saturation voltage bipolar transistors. It is often paired with NPN counterparts like the 2SD1803 for complementary push-pull configurations. The series is engineered for compact designs where small package size and high linearity are critical for performance.

Single Bipolar Transistors Replacement Considerations

Check for direct substitutes such as the 2SB1131 or other onsemi PNP transistors with identical 20V/5A ratings. Verify that any replacement maintains the same TO-92VAR footprint and hFE characteristics to ensure circuit compatibility.
