• High collector current capability

Single Bipolar Transistors Applications

• Power switching circuits
• Amplifier stages
• General purpose transistor applications

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer lot, as the 2N2812 designation is used by multiple vendors including Solitron and Microsemi. Confirm RoHS compliance requirements, as some sources indicate non-compliance. Ensure the TO-61 package type matches the design constraints. Check for active status from the intended supplier to avoid obsolete stock issues.

Single Bipolar Transistors Selection Notes

Select this component for high-current PNP switching needs requiring a hermetically sealed metal case. Consider the 50 V voltage limit and 10 A current capacity against circuit demands. Evaluate thermal management for the 40 W dissipation rating. Compare alternatives if lead-free compliance is mandatory, as this part may not meet those standards.

Single Bipolar Transistors Part Context

The 2N2812 is a legacy PNP transistor often associated with Microsemi or Microchip Technology branding. It belongs to a family of general-purpose bipolar transistors. The part is frequently cross-referenced with other manufacturers like Solitron, leading to potential variations in absolute maximum ratings between different production sources.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with equivalent PNP transistors in the TO-61 package based on specific electrical parameters.
