2N3705 APM TIN/LEAD

Single Bipolar Transistors Overview

The Central Semiconductor Corp 2N3705 APM TIN/LEAD is an NPN silicon general-purpose bipolar junction transistor (BJT) designed for through-hole mounting. It features a collector-emitter voltage of 30V and a continuous collector current of 800mA. The device offers a power dissipation rating of 625mW and a gain bandwidth product of 100MHz, suitable for audio frequency applications. It is housed in a TO-92-3 package with leaded terminations.

Single Bipolar Transistors Feature Summary

• NPN silicon construction for general-purpose amplification
• Through-hole TO-92-3 packaging for standard board integration
• Leaded terminal configuration for reliable soldering

Single Bipolar Transistors Applications

• Audio frequency amplifier circuits
• General-purpose switching applications
• Small-signal processing stages

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix to confirm lead availability and RoHS compliance status. Confirm that the tin/lead composition matches project requirements. Ensure the TO-92-3 package dimensions align with the target PCB footprint. Validate the manufacturer's standard lead time against production schedules before finalizing orders.

Single Bipolar Transistors Selection Notes

Select this component when a through-hole NPN transistor with moderate current handling is required. The 100MHz gain bandwidth makes it appropriate for audio frequencies rather than high-speed RF. Consider the 625mW power limit for thermal management in enclosed designs compared to higher-power alternatives.

Single Bipolar Transistors Part Context

This part belongs to the family of small-signal bipolar transistors from Central Semiconductor. It serves as a discrete active element for signal conditioning. The TO-92 form factor distinguishes it from surface-mount variants, offering mechanical robustness for prototyping and industrial equipment.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitutes include the 2N3705 APM PBFREE variant for lead-free compliance. Other generic NPN equivalents may be considered if pinout and electrical ratings match exactly.
