2N3806

Bipolar Transistor Arrays Overview

The Central Semiconductor Corp 2N3806 is a PNP low noise dual transistor housed in a TO-78 metal can package. It features a maximum collector current of 50 mA, with VCEO and VCBO ratings of 60 V each. The device has a minimum DC current gain (hFE) of 150 at IC=150 µA and VCE=-10 V, and a saturation voltage VCE(sat) of 1.0 V max at IC=50 mA. Power dissipation is rated at 600 mW total for both dies at TA=25°C. The transition frequency fT is 100 MHz, and hFE matching is specified at 10%.

Bipolar Transistor Arrays Feature Summary

• Low noise design optimized for sensitive signal amplification
• Dual configuration within a single hermetic metal can package
• High DC current gain suitable for precision analog applications

Bipolar Transistor Arrays Applications

• Low noise audio pre-amplifiers
• Precision analog signal conditioning circuits
• RF amplifier stages requiring low noise figure

Bipolar Transistor Arrays Procurement Notes

Verify End of Life status before procurement as the TO-78 package series is discontinued by Central Semiconductor. Confirm availability through authorized distributors or surplus channels. Request last-time buy information if production continuity is required. Ensure compatibility with existing PCB footprints designed for the TO-78 case style.

Bipolar Transistor Arrays Selection Notes

Select this component for applications requiring matched PNP pairs in a low noise environment. Consider the 600 mW total power dissipation limit when designing thermal management for the dual die structure. Verify that the 50 mA collector current rating meets circuit requirements. Check hFE matching specifications if balanced performance between the two transistors is critical.

Bipolar Transistor Arrays Part Context

The 2N3806 belongs to Central Semiconductor's discontinued TO-78 dual transistor lineup. This series includes various NPN and PNP variants like the 2N3807 and 2N3809. The TO-78 package provides hermetic sealing, historically favored for military and high-reliability aerospace applications. The manufacturer has transitioned these devices to End of Life status due to declining demand.
