2SB1238TV2P

Single Bipolar Transistors Overview

The ROHM Semiconductor 2SB1238TV2P is a medium power PNP epitaxial planar silicon transistor housed in an ATV (3-SIP) package. It provides a collector-emitter breakdown voltage of -80V and a continuous collector current of -0.7A. The device features a maximum collector power dissipation of 2W under specific mounting conditions, a transition frequency up to 14MHz, and a DC current gain ranging from 120 to 390 at specified test currents.

Single Bipolar Transistors Feature Summary

• Epitaxial planar construction for high reliability
• High breakdown voltage capability of -80V
• Supports continuous collector current of -0.7A
• Designed as a complement to the 2SD1767 / 2SD1859 NPN transistors

Single Bipolar Transistors Applications

• General-purpose medium power amplification circuits
• Complementary pairs with 2SD1767 or 2SD1859 transistors
• Audio visual equipment
• Office automation equipment
• Communication devices

Single Bipolar Transistors Procurement Notes

Verify the ordering suffix TV2P against official documentation to confirm the specific tape-and-reel packaging quantity of 2500 units per basic order. Ensure the ATV package marking code aligns with design requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet revision before finalizing procurement specifications.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with -80V breakdown and -0.7A current capacity is required. Consider its complementary relationship with the 2SD1767/2SD1859 series for matched performance in push-pull configurations. Evaluate the thermal resistance characteristics based on the intended PCB copper area, as power dissipation ratings depend heavily on mounting conditions.

Single Bipolar Transistors Part Context

The 2SB1238 belongs to a family of medium power transistors manufactured by ROHM Semiconductor using epitaxial planar technology. It shares core electrical characteristics with the 2SB1189 but differs in physical packaging and marking codes. The ATV package variant offers surface-mount integration suitable for automated assembly processes in consumer electronics manufacturing.

Single Bipolar Transistors Replacement Considerations

The 2SB1189 serves as a functional equivalent within the same datasheet specification sheet, sharing identical electrical parameters. Designers should verify pinout compatibility and package dimensions when substituting between the ATV and MPT3 packages to ensure proper board layout alignment.
