2SB1237TV2R

Single Bipolar Transistors Overview

The 2SB1237TV2R is a PNP silicon medium power transistor manufactured by ROHM Semiconductor. It features an epitaxial planar structure and operates with a collector-emitter breakdown voltage of -32V and a maximum DC collector current of -1A. The device provides a minimum DC current gain (hFE) of 120 at -100mA and -3V, with a transition frequency of 150MHz. It is housed in the ATV package, which corresponds to the EIAJ SC-72 form factor.

Single Bipolar Transistors Feature Summary

• Low collector-emitter saturation voltage for efficient switching performance
• Designed as a complementary pair to the 2SD1858 NPN transistor

Single Bipolar Transistors Applications

• General-purpose switching circuits
• Complementary amplifier stages paired with 2SD1858
• Audio visual equipment
• Office automation equipment

Single Bipolar Transistors Procurement Notes

Verify the specific hFE bin classification required for the design, as the 'R' suffix indicates a gain range of 180 to 390. Confirm that the ATV/SC-72 through-hole package dimensions match the target PCB footprint. Ensure the operating conditions remain within the absolute maximum ratings, particularly regarding single-pulse collector current limits.

Single Bipolar Transistors Selection Notes

Select this component when a low VCE(sat) PNP transistor is needed to complement an existing 2SD1858 NPN circuit. The ATV package offers a compact through-hole solution suitable for general electronic devices. Consider the hFE 'R' grade if higher current gain consistency is required compared to the standard 'Q' grade.

Single Bipolar Transistors Part Context

This part belongs to the 2SB1237 series of medium power transistors from ROHM. It shares electrical characteristics with the 2SA1515S but utilizes a different physical package. The series is designed for general-use applications and is not intended for radiation-tolerant or high-reliability safety systems such as medical or aerospace equipment.

Single Bipolar Transistors Replacement Considerations

The 2SA1515S is electrically compatible but uses the SPT/EIAJ SC-72 package instead of the ATV package. Verify mechanical fit before substitution.
