Single Bipolar Transistors datasheet and documents for KTC3198-GR A1G

KTC3198-GR A1G

Single Bipolar Transistors Overview

The KTC3198-GR A1G is an NPN epitaxial planar bipolar transistor manufactured by Taiwan Semiconductor in a TO-92 plastic package. It is designed for general-purpose switching and audio frequency amplifier applications. The device features a collector current rating of 0.15A, a collector-emitter voltage of 50V, and a collector-base voltage of 60V. The GR ranking specifies a DC current gain (hFE) range of 200 to 400 at VCE=6V and IC=2mA. It operates within a junction temperature range of -55°C to +150°C.

Single Bipolar Transistors Feature Summary

Subdivided into four hFE groups including O, Y, GR, and BL for precise gain selection
Compliant with Pb-free and RoHS environmental standards
Guaranteed high-temperature soldering capability up to 260°C for 10 seconds

Single Bipolar Transistors Applications

General purpose switching circuits
Audio frequency (AF) amplifiers

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm the exact hFE binning class and packaging configuration. Ensure the component meets the required thermal resistance and power dissipation limits for the intended operating environment. Confirm that the TO-92 package dimensions align with the target PCB footprint and assembly process requirements.

Single Bipolar Transistors Selection Notes

Select this component when a moderate DC current gain between 200 and 400 is required for small signal applications. The TO-92 package suits through-hole mounting designs. Consider the complementary PNP transistor for push-pull configurations. Evaluate the transition frequency and noise characteristics if high-frequency performance is critical for the specific circuit topology.

Single Bipolar Transistors Part Context

This part belongs to the KTC3198 series of small signal NPN transistors produced by Taiwan Semiconductor. The series includes variants with different hFE classifications such as O, Y, and BL. These transistors are commonly used in consumer electronics and industrial control boards where reliable switching and low-power amplification are necessary.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include other NPN transistors from the same family, such as KTC3198-O or KTC3198-Y, provided their hFE ranges meet the circuit requirements. Verify pinout compatibility and electrical ratings before substitution.
