2SD1859TV2R

Single Bipolar Transistors Overview

The ROHM Semiconductor 2SD1859TV2R is an NPN silicon medium power transistor housed in the ATV (TO-92) package. It features a collector-emitter breakdown voltage of 80V and a continuous collector current rating of 0.7A. The device provides a DC current gain (hFE) ranging from 120 to 390 at VCE=3V and IC=0.1A, with a transition frequency (fT) of up to 120MHz. Maximum collector power dissipation is 0.5W on a standard printed circuit board. The TV2 suffix indicates a taping packaging format with a basic ordering quantity of 2500 units.

Single Bipolar Transistors Feature Summary

• High breakdown voltage capability of 80V for collector-base and collector-emitter configurations.
• Medium power handling with a continuous collector current rating of 0.7A.
• Wide DC current gain range supporting consistent amplification performance.
• Transition frequency up to 120MHz suitable for general-purpose switching and amplification.

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Switching applications in consumer electronics
• Complementary pairing with PNP transistors such as the 2SB1189 or 2SB1238

Single Bipolar Transistors Procurement Notes

Verify that the specific marking code corresponds to the ATV package designation when inspecting incoming inventory. Confirm the presence of the TV2 suffix to ensure the component is supplied in the correct taping configuration rather than loose bulk. Cross-reference the manufacturer part number against official ROHM documentation to validate authenticity before integration into production lines.

Single Bipolar Transistors Selection Notes

Select this component when an NPN transistor requires an 80V collector-emitter voltage rating and moderate current handling capabilities around 0.7A. The wide hFE range accommodates various biasing requirements without strict binning constraints. Ensure the thermal design supports a maximum power dissipation of 0.5W under standard PCB mounting conditions.

Single Bipolar Transistors Part Context

This transistor belongs to the 2SD series of NPN silicon transistors manufactured by ROHM Semiconductor. It serves as a complementary counterpart to specific PNP devices within the same product family, facilitating balanced push-pull or differential amplifier designs. The ATV package provides a standardized footprint for through-hole mounting on printed circuit boards.

Single Bipolar Transistors Replacement Considerations

The 2SD1767 is documented as a direct electrical complement within the same datasheet specification sheet. Verify pinout compatibility and package dimensions before substituting, as both utilize the TO-92 form factor but may differ in internal marking codes.
