2SA1514KT146R

Single Bipolar Transistors Overview

The ROHM Semiconductor 2SA1514KT146R is a PNP high-voltage amplifier transistor designed for robust performance in demanding electronic circuits. 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, supporting junction temperatures up to +150°C. Key electrical characteristics include a DC current gain (hFE) ranging from 180 to 560 under specified conditions, ensuring reliable amplification. Packaged in the SMT3 (SOT-346/SC-59) surface-mount format, it offers a compact footprint suitable for space-constrained designs.

Single Bipolar Transistors Feature Summary

• High breakdown voltage capability of -120V for collector-base and collector-emitter configurations.
• Complements complementary NPN transistors such as the 2SC4102, 2SC3906K, and 2SC2389S.

Single Bipolar Transistors Applications

• High-voltage amplifier circuits requiring robust PNP switching or signal amplification.
• Driver stages in audio frequency applications where high voltage tolerance is necessary.
• General-purpose low-power amplification tasks within automotive or industrial environments.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'T146' corresponds to the required tape-and-reel packaging quantity of 3000 pieces per unit. Confirm that the SMT3 package dimensions align with your PCB footprint requirements. Ensure design margins account for the 0.2W power dissipation limit at expected operating temperatures. Cross-reference the hFE binning if precise gain matching is critical for your application circuitry.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with -120V breakdown voltage is required in a small surface-mount package. It serves as a direct complement to NPN devices like the 2SC4102 in push-pull or differential amplifier configurations. Consider the 0.2W power rating and -50mA current limit for thermal management. The SMT3 package offers a balance between size and thermal performance for general-purpose amplification needs.

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. These devices are engineered for high reliability and are often utilized in automotive-grade applications due to their robust voltage handling capabilities. The 2SA1514KT146R specifically denotes the version packaged in the SMT3 form factor with reel-based supply.

Single Bipolar Transistors Replacement Considerations

The 2SA1579U3HZG is documented as a similar specification part with comparable electrical characteristics but utilizes the UMT3 (SOT-323) package instead of SMT3. Designers must verify pinout compatibility and physical footprint differences before substituting. No other direct substitutes are confirmed in the provided documentation.
