2SC5939G0L

Overview

The Panasonic 2SC5939G0L is a silicon NPN epitaxial planar transistor designed for high-frequency amplification, oscillation, and mixing applications. It features a high transition frequency (fT) of up to 2.7 GHz and low parasitic capacitance, including a collector output capacitance (Cob) of 1.4 pF and reverse transfer capacitance (Crb) of 0.45 pF at VCB = 4 V. The device operates with a maximum collector-emitter voltage (VCEO) of 10 V and a collector current (IC) of 50 mA. Packaged in the compact SSS-Mini type (SOT-346), it supports automatic insertion via tape packing.

Feature Summary

• High transition frequency suitable for RF signal processing
• Low collector output and reverse transfer capacitance for minimal signal loss
• Compact SSS-Mini package enabling equipment downsizing

Applications

• High-frequency amplification circuits
• Oscillation circuits
• Mixing circuits

Procurement Notes

Verify the specific ordering suffix 'G0L' against the manufacturer's latest documentation to confirm packaging details and availability status. Check the official Panasonic semiconductor lifecycle page for current maintenance or discontinuation classifications before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring an NPN transistor with a transition frequency exceeding 2 GHz and low input capacitance. Ensure the operating collector-emitter voltage remains within the 10 V limit and that thermal management accommodates the 100 mW power dissipation rating at 25°C ambient temperature.

Part Context

This part belongs to the 2SC5939 series of high-frequency silicon NPN transistors manufactured by Panasonic Electronic Components. It utilizes an epitaxial planar structure optimized for RF performance. The 'G0L' suffix typically denotes the specific tape-and-reel packaging configuration for automated assembly processes.

Replacement Considerations

Consult the official Panasonic replacement guide for verified substitutes. Cross-reference key parameters such as fT, VCEO, and package dimensions (SSS-Mini) when evaluating alternative components from other manufacturers.
