2SB1412TLR

Single Bipolar Transistors Overview

The 2SB1412TLR is a PNP silicon epitaxial planar transistor in the CPT3 (TO-252) surface-mount package. It features a collector-emitter voltage of -20V and a continuous collector current of -5A. The device offers a transition frequency of 120MHz and a maximum power dissipation of 1W on a PCB or 2W at case temperature. DC current gain ranges from 82 to 390 depending on the grade, with a typical saturation voltage of -0.35V at high currents.

Single Bipolar Transistors Feature Summary

• Low collector-emitter saturation voltage for efficient switching
• High DC current gain characteristics across operating ranges
• Complements specific NPN transistors in push-pull configurations

Single Bipolar Transistors Applications

• General-purpose low-frequency amplification
• Driver circuits for power loads
• Switching applications requiring moderate current handling

Single Bipolar Transistors Procurement Notes

Verify the hFE grading suffix (Q or R) required for your circuit's gain specifications, as these are distinct ordering options within the TLR series. Confirm that the CPT3 package dimensions match your PCB footprint. Check for the NRND status if designing new equipment, as this component may be phased out.

Single Bipolar Transistors Selection Notes

Select this component when a -20V PNP transistor with 5A capability is needed in a TO-252 package. Ensure the thermal management design supports the 1W PCB dissipation limit. Verify that the complementary NPN device matches the intended application requirements for balanced performance.

Single Bipolar Transistors Part Context

This part belongs to the 2SB1386/1412/1326 family of low-voltage, high-current PNP transistors manufactured by Rohm Semiconductor. These devices share similar electrical profiles but differ in packaging and specific gain classifications. The 2SB1412 is specifically designated for the CPT3 surface-mount form factor.

Single Bipolar Transistors Replacement Considerations

Publicly confirmed substitutes include the 2SB1205S-TL-E and 2SB1412-R-TP. Verify pinout compatibility and electrical ratings before substitution, as package types and exact gain grades may vary between manufacturers.
