Single Bipolar Transistors datasheet and documents for 2SD0946B

2SD0946B

Single Bipolar Transistors Overview

The Panasonic 2SD0946B is a silicon NPN epitaxial planar type Darlington transistor designed for low-frequency amplification. It features a high forward current transfer ratio (hFE) ranging from 4,000 to 40,000 depending on the rank classification. The device supports a collector current of 1 A and a peak collector current of 1.5 A. Key electrical ratings include a collector-emitter voltage (VCEO) of 80 V and a collector-base voltage (VCBO) of 100 V. It operates within a junction temperature range up to 150 °C and utilizes a TO-126B-A1 package.

Single Bipolar Transistors Feature Summary

High forward current transfer ratio suitable for motor and printer hammer driver circuits
Eliminates the need for shunt resistors in driver designs
Silicon NPN epitaxial planar construction

Single Bipolar Transistors Applications

Motor driver circuits
Printer hammer driver circuits
Low-frequency amplification

Single Bipolar Transistors Procurement Notes

Verify component status as maintenance or discontinued via official channels before design finalization. Confirm specific hFE rank requirements (Q, R, or S) during procurement to ensure performance alignment with circuit needs. Ensure compliance with RoHS directives applicable to the manufacturing region.

Single Bipolar Transistors Selection Notes

Select this component when high gain is required for driving loads such as motors or print mechanisms without additional shunt resistors. Consider the 80 V collector-emitter voltage rating for appropriate voltage headroom. Evaluate thermal management capabilities given the 1.2 W power dissipation limit at 25 °C ambient temperature.

Single Bipolar Transistors Part Context

This part belongs to the 2SD0946 series, which includes the 2SD0946A variant. Both are silicon NPN Darlington transistors intended for general-purpose low-frequency amplification tasks. The series is manufactured by Panasonic Electronic Components.
