2N3700 PBFREE

Single Bipolar Transistors Overview

The Central Semiconductor 2N3700 PBFREE is a silicon NPN transistor housed in a TO-18 metal can package. It supports a continuous collector current of 1.0 A and withstands a collector-emitter voltage of 80 V. The device dissipates 500 mW at ambient temperature and 1.8 W with case cooling. Junction temperatures range from -65 to +200 °C. DC current gain (hFE) spans 15 to 400 depending on collector current. Transition frequency reaches up to 400 MHz, and noise figure is limited to 4.0 dB.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix when purchasing. The 'PBFREE' designation indicates lead-free plating compliance. Requesting tin/lead plated devices requires adding the 'TIN/LEAD' suffix to the part number during the order process. Confirm mechanical outline compatibility with existing TO-18 footprints before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring robust NPN switching or amplification within a hermetic metal package. Evaluate thermal management requirements carefully, as power dissipation drops significantly without case cooling. Compare hFE ranges against load requirements to ensure adequate drive capability across the specified operating temperature spectrum.

Single Bipolar Transistors Part Context

This component belongs to the Central Semiconductor 2N3700 and 2N3701 series of silicon NPN transistors. Both variants share identical maximum ratings and electrical characteristics. The primary distinction lies in the minimum DC current gain specifications under various test conditions. They utilize standard TO-18 packaging with emitter, base, and collector lead configurations.

Single Bipolar Transistors Replacement Considerations

The 2N3701 serves as a direct functional substitute with identical ratings but different gain thresholds.
