2SA1514KT146S

Single Bipolar Transistors Overview

The ROHM Semiconductor 2SA1514KT146S is a PNP general-purpose amplifier transistor designed for high-voltage applications. It features a collector-emitter breakdown voltage (BVCEO) of -120V and a maximum continuous collector current (IC) of -50mA. The device operates with a collector power dissipation (PC) of 0.2W at 25°C ambient temperature. Key electrical characteristics include a DC current gain (hFE) range of 180 to 560, measured at VCE=-6V and IC=-2mA. The transition frequency (fT) is specified at 140MHz under conditions of VCE=-12V, IE=2mA, and f=30MHz. The component utilizes an SMT3 (SC-59/SOT-346) surface-mount package.

Single Bipolar Transistors Feature Summary

• High breakdown voltage capability of -120V for robust operation in demanding circuits.
• Designed to complement the 2SC4102 NPN transistor for matched pair applications.

Single Bipolar Transistors Applications

• General-purpose amplification stages requiring high voltage tolerance.
• Complementary driver circuits paired with 2SC4102 transistors.
• Switching applications within the specified thermal and current limits.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix T146 corresponds to the required tape-and-reel packaging quantity of 3000 units. Confirm that the SMT3 package dimensions align with your PCB footprint requirements. Ensure design parameters remain within the absolute maximum ratings, particularly the 0.2W power dissipation limit at 25°C ambient temperature. Check for any RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with -120V breakdown voltage is required in a compact SMT3 package. It serves as a direct functional complement to the 2SC4102 NPN transistor. Consider the hFE range of 180-560 for gain stability. Evaluate the 0.2W power dissipation against your thermal management strategy. This part is suitable for general-purpose amplification where high voltage isolation is critical.

Single Bipolar Transistors Part Context

The 2SA1514K belongs to a family of high-voltage amplifier transistors manufactured by ROHM Semiconductor, sharing specifications with the 2SA1579 and 2SA1038S. While these variants share identical electrical ratings, they differ in packaging: the 2SA1514K uses the SMT3 form factor, whereas the 2SA1579 utilizes UMT3 and the 2SA1038S uses SPT. This family is engineered for general-purpose amplification tasks requiring reliable performance at elevated voltages.

Single Bipolar Transistors Replacement Considerations

The 2SA1579 is listed as a similar level replacement with the same pinout and package type UMT3, but differs from the SMT3 package of the 2SA1514K. No other direct substitutes are documented in the provided source material.
