2SB1203S-TL-E

Single Bipolar Transistors Overview

The onsemi 2SB1203S-TL-E is a PNP silicon bipolar junction transistor in the TP-FA (SC-63/TO-252) surface-mount package. It supports a maximum collector current of 5 A and a collector-emitter voltage of -50 V. The device features a gain-bandwidth product of 180 MHz at 1 A, with a typical collector-to-emitter saturation voltage of -280 mV under specified drive conditions. Thermal management allows for up to 2 W power dissipation when mounted to a case at 25°C.

Single Bipolar Transistors Feature Summary

• Low collector-to-emitter saturation voltage for efficient switching
• High current handling capability combined with high transition frequency
• Fast switching speed suitable for high-frequency applications
• Small and slim package design facilitating compact circuit layouts

Single Bipolar Transistors Applications

• Converters
• General high-current switching applications

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'TL' corresponds to the TP-FA tape-and-reel packaging configuration containing 700 pieces per reel. Confirm that the component meets Pb-Free requirements as indicated in the manufacturer's ordering information table. Ensure the selected variant matches the required lead-free or halogen-free status for your assembly process.

Single Bipolar Transistors Selection Notes

Select this component for circuits requiring robust PNP switching with low saturation losses. Consider the thermal resistance characteristics when designing heat dissipation paths, as the TO-252 package relies heavily on PCB copper area or heatsinking for optimal performance above ambient temperature ratings.

Single Bipolar Transistors Part Context

This part belongs to the 2SB1203/2SD1803 series, which pairs PNP and NPN transistors designed for complementary high-current applications. The series utilizes FBET and MBIT processes to achieve fast switching speeds and excellent linearity. It serves as a discrete alternative to integrated power transistor modules in industrial and consumer electronics.

Single Bipolar Transistors Replacement Considerations

Direct functional equivalents include the 2SD1803T-TL-E (NPN counterpart) and other variants within the 2SB1203 family such as the 2SB1203S-H. Verify pinout compatibility and electrical parameters against the original design specifications before substitution.
