2N2107

Single Bipolar Transistors Overview

The 2N2107 is an NPN silicon small-signal transistor manufactured by Microchip Technology, housed in a TO-39 metal can package. It supports a collector-emitter voltage of 90 V and a continuous collector current of 1000 mA. The device operates within a temperature range of -65 °C to +175 °C. Key electrical characteristics include a DC current gain (hFE) ranging from 5.0 to 7.0 depending on the specific grade, with a maximum collector-base leakage current of 50 nA at specified conditions.

• Designed for general-purpose amplification and switching applications requiring moderate power handling

Single Bipolar Transistors Applications

• High-temperature industrial control circuits
• Military and aerospace signal processing systems
• Automotive engine management sensors

Single Bipolar Transistors Procurement Notes

Verify the manufacturer designation carefully, as historical data indicates New Jersey Semiconductor as the producer for this specific part number. Confirm RoHS compliance status, as legacy TO-39 packages often carry non-compliant markings. Ensure the supplier provides official datasheets confirming the 90 V rating and 1 A current capacity before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a ruggedized, hermetically sealed transistor is required for extreme environments. The TO-39 package offers superior heat dissipation compared to plastic equivalents. Verify that the required hFE range aligns with the available grades, as the datasheet specifies a wide variation in current gain between different binning levels.

Single Bipolar Transistors Part Context

This component belongs to the legacy discrete semiconductor category, originally standardized under the 2N series numbering system. While Microchip Technology is listed as the brand, the specific manufacturing origin may trace back to acquired lines or legacy partners. It serves as a replacement for older designs requiring reliable NPN performance in harsh conditions.

Single Bipolar Transistors Replacement Considerations

Direct substitutes must match the TO-39 footprint and 90 V / 1 A ratings. Common equivalents include the 2N344 or similar military-grade NPN transistors. Verify pinout compatibility and ensure the replacement meets the same thermal and leakage specifications.
