2SC1573AQ

Single Bipolar Transistors Overview

The Panasonic 2SC1573AQ is a silicon NPN triple diffusion planar transistor designed for high breakdown voltage general amplification and small TV video output applications. It operates in an EIAJ SC-51 (TO-92L-A1) package with three leads. The device supports a collector current of 70 mA and peak current of 100 mA, with power dissipation up to 1 W at 25°C. Transition frequency ranges from 50 to 80 MHz. Collector-emitter voltage varies by suffix: 200 V for standard, 300 V for 'A', and 400 V for 'B'.

Single Bipolar Transistors Feature Summary

• High collector-emitter voltage capability suitable for demanding amplification tasks.
• Optimized transition frequency for signal processing in video output circuits.
• Triple diffusion planar construction ensures stable electrical characteristics.

Single Bipolar Transistors Applications

• Small TV video output stages
• General amplification circuits requiring high breakdown voltage
• Driver amplification in consumer electronics

Single Bipolar Transistors Procurement Notes

Verify the specific suffix (A or B) against design requirements, as it dictates the maximum collector-emitter voltage rating. Confirm the component lifecycle status via official channels, as maintenance or discontinuation notices may apply. Ensure compliance with RoHS directives if required by the target market regulations.

Single Bipolar Transistors Selection Notes

Select based on the required collector-emitter voltage breakdown; choose the 'A' variant for 300V or 'B' for 400V ratings. Consider the complementary 2SA0879 PNP transistor for push-pull configurations. Evaluate thermal management needs given the 1W power dissipation limit in the TO-92L-A1 package.

Single Bipolar Transistors FAQ

What is the difference between the 2SC1573A and 2SC1573B variants?

The primary difference is the maximum collector-emitter voltage rating. The 2SC1573A supports 300 V, while the 2SC1573B supports 400 V.

Is this transistor suitable for aerospace applications?

No. The documentation explicitly states that these products are intended for standard applications like household appliances and office equipment, not for special applications such as aerospace where exceptional reliability is required.
