2N6193U3

Overview

The Microchip Technology 2N6193U3 is a PNP silicon small-signal bipolar junction transistor (BJT) designed for medium-power applications. It features a hermetically sealed metal can TO-39 package with three bottom-mounted wire terminals. The device supports a maximum collector current of 5 A and withstands collector-emitter and collector-base voltages up to 100 V. Qualified under MIL-PRF-19500/561 standards, it operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a minimum DC current gain (hFE) of 40 and a total power dissipation rating of 10 W.

Feature Summary

• Hermetically sealed metal can construction ensures reliability in harsh environments
• Qualified per MIL-PRF-19500/561 military specifications for high-reliability use
• High thermal stability supporting operation up to +200°C junction temperature
• Medium-power capability with 5 A continuous collector current handling

Applications

• Military aerospace electronic systems requiring radiation and vibration resistance
• High-reliability industrial power control circuits
• Harsh environment signal amplification and switching applications

Procurement Notes

Verify the specific qualification level (JAN, JANTX, or JANTXV) required for your design, as these levels dictate performance tolerances and testing rigor. Confirm that the TO-39 metal package aligns with your thermal management and mechanical constraints. Ensure compliance with relevant military procurement standards if operating in defense sectors. Check for RoHS exemptions due to the lead-based termination typically associated with this legacy hermetic package style.

Selection Notes

Select this component when hermetic sealing and extreme temperature tolerance are mandatory. The TO-39 package offers superior heat dissipation compared to plastic equivalents but requires appropriate mounting hardware. Consider the 100 V voltage rating for medium-voltage switching tasks. Evaluate the hFE range against your base drive requirements to ensure adequate saturation or amplification margins in your circuit topology.

Part Context

The 2N6193 series belongs to Microchip's portfolio of qualified discrete semiconductors derived from historical military specifications. These devices are engineered for longevity and consistency in critical infrastructure. The U3 suffix typically denotes a specific variant within the broader 2N6193 family, often related to packaging or specific test criteria defined by the manufacturer's internal coding or distributor listings.

Replacement Considerations

Direct replacements must match the TO-39 hermetic package and PNP polarity. Verify that substitute parts meet or exceed the 100 V breakdown voltage and 5 A current ratings. Ensure any alternative device maintains compatibility with the -65°C to +200°C operating range if environmental resilience is required.
