2SD1859TV2Q

Single Bipolar Transistors Overview

The ROHM Semiconductor 2SD1859TV2Q is a single NPN silicon bipolar junction transistor housed in an ATV (SC-62) surface-mount package. It features a collector-emitter breakdown voltage of 80V and a continuous collector current rating of 0.7A. The device supports a maximum power dissipation of 0.5W on a standard printed circuit board and operates within a junction temperature range up to 150°C. Electrical characteristics include a DC current gain (hFE) ranging from 120 to 390 at VCE=3V and IC=0.1A, with a transition frequency (fT) of 120MHz.

Single Bipolar Transistors Feature Summary

• High breakdown voltage capability of 80V for collector-base and collector-emitter configurations.
• Designed as a complementary component to the 2SB1189 and 2SB1238 PNP transistors.
• Optimized for medium-power applications with a 0.7A continuous collector current capacity.

Single Bipolar Transistors Applications

• Complementary driver circuits utilizing paired NPN/PNP transistor sets.
• Medium-power switching applications requiring high voltage tolerance.
• General-purpose amplification stages in consumer electronic devices.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix TV2Q against official ROHM documentation to confirm the ATV package type and hFE ranking. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before finalizing procurement specifications.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits that require an 80V NPN transistor with a 0.7A current limit. Ensure the thermal design accommodates the 0.5W power dissipation rating under expected operating conditions. Verify compatibility with the intended PCB footprint for the ATV/SC-62 package style.

Single Bipolar Transistors Part Context

This part belongs to the 2SD1859 series of medium-power transistors manufactured by ROHM Semiconductor. It shares electrical specifications with the 2SD1767 but utilizes a distinct ATV package configuration. The series is engineered for general-purpose use in audio visual equipment and office automation machinery.

Single Bipolar Transistors Replacement Considerations

The 2SD1767 serves as a direct functional substitute with identical electrical ratings. For complementary PNP requirements, the 2SB1189 or 2SB1238 are specified as matching pairs within the same product family.
