Single Bipolar Transistors datasheet and documents for 2SB1474TL

2SB1474TL

Single Bipolar Transistors Overview

The Rohm Semiconductor 2SB1474TL is a PNP power transistor featuring a Darlington connection for high hFE, housed in a CPT3 (SC-63) package. It supports -80V collector-emitter voltage and -4A DC collector current with 1W dissipation at 25°C case temperature. Key electrical characteristics include a minimum hFE of 1000 at IC/IB = -2A/-4mA, transition frequency of 12MHz, and built-in base-emitter resistor (R1=3kΩ) and damper diode (R2=300Ω).

Single Bipolar Transistors Feature Summary

Darlington configuration provides high DC current gain.
Integrated base-emitter resistor simplifies circuit design.
Built-in damper diode protects against reverse voltage spikes.

Single Bipolar Transistors Applications

High-gain amplification stages
Driver circuits requiring high input impedance
Power switching applications

Single Bipolar Transistors Procurement Notes

Verify the ordering suffix 'TL' corresponds to the 2500-piece taping quantity specified in the datasheet. Confirm the CPT3 package dimensions match your PCB footprint requirements. Ensure thermal management supports 1W dissipation at Tc=25°C. Check RoHS compliance status if required by your manufacturing standards.

Single Bipolar Transistors Selection Notes

Select this component when high current gain is critical without external biasing networks. The integrated resistors reduce component count. Consider the -80V rating for appropriate voltage headroom. Evaluate thermal constraints given the 1W power dissipation limit. Compare transition frequency specifications against signal speed requirements.

Single Bipolar Transistors Part Context

This part belongs to Rohm's discrete transistor portfolio, specifically designed for power applications requiring robust switching capabilities. The CPT3 package offers a balance between power handling and board space efficiency compared to larger TO-252 variants.

Single Bipolar Transistors Replacement Considerations
