2N720A

Single Bipolar Transistors Overview

The Microchip Technology 2N720A is a general-purpose NPN silicon transistor designed for low-power amplification and switching applications. It features a collector-emitter voltage rating of 40V, a collector current capacity of 100mA, and a DC current gain (hFE) ranging from 70 to 350 depending on the specific grade. The device operates within a junction temperature range of -65°C to +200°C and is available in standard through-hole packages such as TO-92. It is commonly utilized in audio pre-amplifiers, signal processing circuits, and general electronic switching tasks requiring reliable NPN performance.

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer source, as historical 2N720A parts were originally defined by military standards. Confirm package type compatibility, typically TO-92, and check for RoHS compliance if required for modern assembly. Ensure the supplier provides valid traceability documentation for this legacy component designation.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with 40V Vceo and 100mA Ic is required. Compare hFE grades against circuit gain requirements. Consider thermal management for continuous operation near maximum ratings. Verify pinout alignment with existing PCB footprints before integration.

Single Bipolar Transistors Part Context

The 2N720A belongs to the family of general-purpose NPN bipolar junction transistors. Historically significant in electronics design, it serves as a fundamental building block for discrete amplifier stages. While newer integrated solutions exist, this discrete part remains relevant for simple, cost-sensitive designs requiring robust switching or linear amplification capabilities.

Single Bipolar Transistors Replacement Considerations

Common substitutes include the 2N3904 for similar switching characteristics or the 2N2222 for higher frequency applications. Verify pinout compatibility and ensure replacement devices meet the original 40V and 100mA specifications.
