2N3397 TIN/LEAD

Single Bipolar Transistors Overview

The Central Semiconductor Corp 2N3397 TIN/LEAD is an NPN silicon bipolar junction transistor (BJT) housed in a TO-92-3 through-hole package. It features a collector-base voltage (VCBO) of 25 V, a collector-emitter voltage (VCEO) of 25 V, and an emitter-base voltage (VEBO) of 5 V. The device supports a maximum power dissipation of 360 mW and operates within a temperature range of -65°C to +150°C. With a minimum DC current gain (hFE) of 55 at 4.5 V and 2 mA, it is designed for low-level, low-noise amplifier applications.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'TIN/LEAD' to confirm leaded terminations, as this affects RoHS compliance status. Ensure the procurement channel provides official datasheets from Central Semiconductor or authorized distributors. Confirm that the TO-92-3 package variant matches the design requirements for through-hole mounting. Request batch-specific electrical parameter data if strict hFE binning is required for precision analog designs.

Single Bipolar Transistors Selection Notes

Select the 2N3397 when low noise and small-signal amplification are prioritized over high-power handling. Compare its 25 V voltage ratings against circuit supply voltages to ensure adequate headroom. Consider the 360 mW power dissipation limit for thermal management in enclosed environments. Evaluate the TO-92-3 footprint compatibility with existing PCB layouts before finalizing the component choice for production.

Single Bipolar Transistors Part Context

This component belongs to the MPS3397 series family of silicon NPN transistors manufactured by Central Semiconductor. It serves as a general-purpose small-signal device suitable for audio and RF stages. The part is distinct from higher-power variants like the 2N3393, which offers greater current handling capabilities. It is commonly used in consumer electronics and industrial control systems requiring reliable low-noise performance.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitute part numbers include the MPS3397 TIN/LEAD, which shares identical specifications and pinout configurations. Verify mechanical dimensions and electrical parameters before substitution to ensure functional equivalence in sensitive low-noise circuits.
