KSA733CGTA

Single Bipolar Transistors Overview

The KSA733CGTA is a PNP epitaxial silicon transistor manufactured by Fairchild Semiconductor, now part of ON Semiconductor. It operates with a collector current of -150 mA and a collector-emitter voltage of -50 V. The device features a collector-base breakdown voltage of -60 V and an emitter-base breakdown voltage of -5 V. It has a maximum power dissipation of 250 mW at 25°C ambient temperature. The junction temperature rating reaches 150°C. The DC current gain ranges from 40 to 700 depending on the classification bin. The transition frequency is up to 180 MHz.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Applications

• Low frequency amplifier circuits
• General purpose switching applications
• Complementary output stages paired with KSC945

Single Bipolar Transistors Procurement Notes

Verify the exact ordering suffix against the official ON Semiconductor database, as legacy Fairchild part numbers containing underscores may have been converted to dashes in current systems. Confirm availability status, as this component may be discontinued or subject to lifecycle changes following the corporate integration. Ensure the center-collector pinout matches the specific circuit design requirements before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when a PNP small-signal transistor with a center-collector lead arrangement is required. The wide hFE range allows for flexible biasing strategies across different production bins. Verify that the -50V collector-emitter voltage rating meets the circuit's maximum operating conditions. Consider the complementary KSC945 if a matched pair topology is necessary for the application design.
