2N3811U

Bipolar Transistor Arrays Overview

The Microsemi Corporation 2N3811U is a dual small-signal bipolar junction transistor (BJT) constructed from silicon. It features a PNP configuration with two independent elements integrated into a single package. The device is housed in a TO-78 metal can package, which is similar to the standard TO-78 form factor and provides six pins for connection. Key electrical specifications include a maximum DC collector current of 0.05 A and a collector-emitter breakdown voltage of 60 V. This component is designed for high-reliability applications requiring hermetic sealing.

Bipolar Transistor Arrays Feature Summary

• Dual element PNP configuration within a single package
• Hermetically sealed metal can construction
• High reliability design suitable for demanding environments

Bipolar Transistor Arrays Applications

• Military aerospace circuits
• Spacecraft electronic systems
• High-reliability signal processing

Bipolar Transistor Arrays Procurement Notes

Verify the specific manufacturer source, as JAN2N3811 variants are produced by multiple entities including Raytheon Company and Semicoa. Confirm that the Microsemi version matches the required pinout and hermetic seal standards. Check for discontinuation notices or limited availability status before finalizing procurement plans.

Bipolar Transistor Arrays Selection Notes

Select this component when a dual PNP BJT with hermetic sealing is required. Ensure the circuit design accommodates the 6-pin TO-78 package dimensions. Verify that the 60V breakdown voltage and 50mA current limits align with the operational requirements of the target application.

Bipolar Transistor Arrays Part Context

This part belongs to the 2N3811 series of dual small-signal transistors. It shares functional similarities with other JAN-series devices but is distinguished by its specific packaging and manufacturer-specific qualification standards. The U suffix typically denotes a specific variant within the broader family.

Bipolar Transistor Arrays Replacement Considerations

Cross-reference with JAN2N3811L or JAN2N3811U from other manufacturers like Semicoa. Verify pin compatibility and electrical parameters before substitution.
