2SA1036KT146R

Single Bipolar Transistors Overview

The 2SA1036KT146R is a PNP bipolar junction transistor manufactured by Rohm Semiconductor. It features a collector-emitter voltage (VCEO) of -32 V and a maximum collector current (IC) of -500 mA. The device has a power dissipation rating of 200 mW at 25°C ambient temperature. It utilizes an SOT-346 (SMT3) surface-mount package with three terminals. The DC current gain (hFE) ranges from 82 to 390, classified into ranks P, Q, and R. Transition frequency (fT) reaches 200 MHz under specified conditions.

Single Bipolar Transistors Feature Summary

• Designed for low-voltage operation with low collector-emitter saturation voltage.
• Provides high collector current capability suitable for general-purpose small signal amplification.
• Functions as a complementary device to the 2SC2411K NPN transistor.

Single Bipolar Transistors Applications

• General purpose small signal amplifier circuits
• Low-voltage operating electronic systems

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank (P, Q, or R) required for your design, as the base part number covers multiple gain classifications. Confirm that the SOT-346 footprint matches your PCB layout. Ensure the application does not involve automotive or medical equipment, as these are excluded from standard use cases. Check storage conditions to maintain solderability before assembly.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with -32 V breakdown and -500 mA current handling is needed in a compact SMT3 package. Consider the hFE classification based on the required gain consistency for your amplifier stage. Verify thermal management capabilities, as the 200 mW dissipation limit requires adequate heat sinking or board copper area. Ensure compatibility with the complementary 2SC2411K if used in push-pull configurations.

Single Bipolar Transistors Part Context

This transistor belongs to Rohm's medium-power discrete transistor lineup designed for surface-mount applications. It is part of a series optimized for general-purpose amplification tasks where space constraints and low saturation voltage are critical. The SOT-346 package allows for high-density mounting on printed circuit boards.

Single Bipolar Transistors Replacement Considerations

The datasheet identifies the 2SC2411K as its complementary NPN counterpart. No direct PNP replacements are listed in the provided documentation. Designers should verify pinout and electrical characteristics if substituting with other -32V PNP transistors in the SOT-346 package.
