2SB1239TV2

Single Bipolar Transistors Overview

The ROHM Semiconductor 2SB1239TV2 is a PNP power transistor featuring a Darlington connection and an integrated 4kΩ base-emitter resistor. It provides a collector current of -2A DC and a collector-emitter voltage of -40V with a power dissipation of 1W at 25°C case temperature. The device offers a high DC current gain (hFE) range of 1,000 to 20,000 and operates within a junction temperature range of -55°C to +150°C.

Single Bipolar Transistors Feature Summary

• Darlington configuration for high DC current gain
• Integrated 4kΩ base-emitter resistor
• Designed as a complement to the 2SD1759 / 2SD1861 NPN transistors

Single Bipolar Transistors Applications

• General-purpose amplification circuits
• Switching applications requiring high gain
• Complementary pairs with specified NPN counterparts

Single Bipolar Transistors Procurement Notes

Verify the specific suffix ATV or T146 against the required packaging format. Confirm RoHS compliance status via official datasheets. Check lead times and availability directly with authorized distributors as standard stock levels vary. Ensure the ordering code matches the exact hFE binning requirements for the target application.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain PNP switch or amplifier is needed in a surface-mount package. The built-in resistor simplifies biasing networks compared to discrete Darlington pairs. Consider the -40V rating and 2A current limit for load requirements. Verify thermal management needs for the SOT-89-3 equivalent footprint if operating near maximum power dissipation limits.

Single Bipolar Transistors Part Context

This part belongs to the 2SB1183/2SB1239 series of power transistors manufactured by ROHM Semiconductor. It shares identical electrical characteristics with the 2SB1183 but differs in packaging and ordering suffixes. The series is designed for general-purpose use in consumer electronics and industrial control systems where compact high-gain switching is required.

Single Bipolar Transistors Replacement Considerations

The 2SB1183 is electrically equivalent to the 2SB1239. Verify pinout compatibility and physical dimensions before substitution. No other direct substitutes are documented in the provided source material.
