Single Bipolar Transistors datasheet and documents for 2SD1478ARL

2SD1478ARL

Single Bipolar Transistors Overview

The Panasonic 2SD1478ARL is a silicon NPN epitaxial planar Darlington transistor designed for low-frequency amplification. It features a Mini3-G1 (EIAJ SC-59) surface-mount package with three pins. The device supports a collector current of 500 mA and a peak collector current of 750 mA, with a maximum power dissipation of 200 mW at 25°C. The 2SD1478A variant provides a collector-emitter voltage rating of 50 V and a collector-base voltage of 60 V. Forward current transfer ratios range from 4,000 to 20,000 depending on the rank classification.

Single Bipolar Transistors Feature Summary

High forward current transfer ratio suitable for motor and printer hammer driver circuits
Darlington configuration eliminates the need for external shunt resistors in driver designs

Single Bipolar Transistors Applications

Motor driver circuits
Printer hammer drivers
Low-frequency amplification

Single Bipolar Transistors Procurement Notes

Verify component authenticity against official Panasonic specifications. Confirm the specific suffix 'A' matches the required 50V collector-emitter voltage rating. Check for RoHS compliance status as per the latest datasheet revision. Ensure the Mini3-G1 package dimensions align with PCB layout requirements. Validate that the high hFE gain meets the design's minimum threshold.

Single Bipolar Transistors Selection Notes

Select this component when high current gain is required without external biasing components. The Mini3-G1 package allows for automated insertion and equipment downsizing. Consider the 2SD1478A variant if higher voltage ratings are necessary compared to the standard 2SD1478. Evaluate thermal management capabilities given the 200 mW power dissipation limit.

Single Bipolar Transistors Part Context

This part belongs to the Panasonic 2SD1478 series of silicon NPN Darlington transistors. It is specifically engineered for applications requiring high gain in compact surface-mount packages. The series is intended for general electronic equipment such as office and communication devices.
