2N6725

Single Bipolar Transistors Overview

The onsemi 2N6725 is a small signal NPN silicon planar medium Darlington transistor housed in a TO-92 compatible E-Line package. It features a maximum collector-emitter voltage of 50V and a continuous collector current rating of 1A. The device offers a minimum DC current gain (hFE) of 4000, making it suitable for high-gain amplification applications. It operates within a temperature range of -65°C to 200°C with a total power dissipation of 1 Watt.

Single Bipolar Transistors Feature Summary

• Medium Darlington configuration providing high current gain
• Silicon planar technology for reliability
• Wide operating temperature range up to 200°C

Single Bipolar Transistors Applications

• High-gain amplifier circuits
• Switching applications requiring moderate current
• Driver stages for relay or lamp loads

Single Bipolar Transistors Procurement Notes

Verify the manufacturer source carefully as the component originates from Zetex Semiconductors, now part of Diodes Incorporated, rather than onsemi directly. Confirm the specific datasheet revision and RoHS compliance status before integration. Ensure the TO-92 pinout matches your PCB footprint requirements. Check for any obsolescence notices or lifecycle changes that may affect long-term supply stability.

Single Bipolar Transistors Selection Notes

Select this component when a single NPN transistor must provide very high current gain without external feedback networks. The 50V collector-emitter voltage rating limits its use in higher voltage switching environments. Consider thermal management due to the 1W power dissipation limit in the TO-92 package. Verify if the 4000 hFE minimum meets your circuit's biasing requirements compared to standard bipolar transistors.

Single Bipolar Transistors Part Context

This device belongs to the family of medium-power Darlington transistors designed for robust switching and amplification. Unlike standard BJTs, the Darlington structure combines two transistors to achieve significantly higher beta values. The TO-92 package provides a cost-effective solution for through-hole mounting in consumer and industrial electronics where space is not critically constrained.
