2SC29250SA

Single Bipolar Transistors Overview

The Panasonic 2SC29250SA is a silicon NPN epitaxial planar transistor designed for low-frequency output amplification. It features a TO-92-B1 package with a maximum collector current of 700 mA and a collector-emitter voltage rating of 50 V. The device offers a high forward current transfer ratio (hFE) ranging from 400 to 2,000 depending on the rank, and a low collector-emitter saturation voltage of 0.4 V maximum at 500 mA. It supports a peak collector current of 1.5 A and operates up to a junction temperature of 150 °C.

Single Bipolar Transistors Feature Summary

• High forward current transfer ratio (hFE) for efficient signal amplification
• Low collector-emitter saturation voltage (VCE(sat)) to minimize power loss
• Silicon NPN epitaxial planar construction for stable performance

Single Bipolar Transistors Applications

• Low-frequency output amplification circuits
• General electronic equipment driver stages
• Household appliance control modules

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank (R, S, or T) required for your design, as gain varies significantly between classifications. Confirm the TO-92-B1 pinout matches your PCB layout, specifically identifying Emitter, Collector, and Base terminals. Check the latest product status via official channels, as this component may be subject to maintenance or discontinuation schedules.

Single Bipolar Transistors Selection Notes

Select this component when high DC current gain is critical for amplifier efficiency. Ensure the operating collector current remains within the 700 mA continuous limit to avoid exceeding the 750 mW power dissipation rating. Consider the thermal derating curve if ambient temperatures exceed 25 °C. Verify that the 50 V collector-emitter voltage provides sufficient headroom for your circuit's supply rails.

Single Bipolar Transistors Part Context

This part belongs to the 2SC2925 series of small-signal bipolar transistors manufactured by Panasonic Industry. It utilizes a standard TO-92-B1 plastic encapsulation suitable for through-hole mounting. The device is compliant with the RoHS Directive (EU 2002/95/EC). It is intended for general-purpose applications in office and communications equipment rather than specialized automotive or aerospace environments.

Single Bipolar Transistors Replacement Considerations

Consult official documentation for verified substitutes. Cross-referencing requires matching the NPN polarity, TO-92-B1 package, and minimum hFE requirements.
