BCV72

Overview

The BCV72 is an NPN general-purpose amplifier transistor manufactured by onsemi, formerly Fairchild Semiconductor. It is housed in a SOT-23 surface-mount package and designed for applications requiring collector currents up to 300 mA. The device features a collector-emitter voltage rating of 60 V and a collector-base voltage of 80 V. Key electrical characteristics include a DC current gain (hFE) ranging from 200 to 450 at a collector current of 2.0 mA, and a maximum total device dissipation of 350 mW. The operating junction temperature range extends from -55°C to +150°C.

Feature Summary

• Designed for general-purpose amplification tasks with support for collector currents up to 300 mA.
• Provides high DC current gain suitable for signal amplification requirements.
• Utilizes a compact SOT-23 surface-mount package for efficient board space utilization.

Applications

• General-purpose signal amplification circuits
• Low-power switching applications
• Audio pre-amplifier stages

Procurement Notes

Verify the specific ordering suffix against the official onsemi website, as part numbers may have transitioned from Fairchild nomenclature during integration. Ensure the component meets RoHS compliance standards required for your manufacturing process. Confirm that the SOT-23 package dimensions align with your PCB footprint design rules before finalizing procurement.

Selection Notes

Select this component when a small-signal NPN transistor with moderate current handling capabilities is required. The wide current gain range allows for flexibility in biasing designs. Consider the thermal resistance and power dissipation limits if operating near the maximum current ratings. The SOT-23 package is ideal for consumer electronics where space constraints are critical.

Part Context

This device belongs to the family of general-purpose bipolar junction transistors produced by onsemi. Originally developed under Fairchild Semiconductor, it remains available through onsemi's portfolio following corporate integration. The part is widely used in standard electronic designs requiring reliable NPN switching or amplification in compact form factors.

Replacement Considerations

Consult the official onsemi database for verified substitute part numbers. Generic replacements must match the NPN configuration, SOT-23 package, and equivalent voltage/current ratings to ensure circuit compatibility without redesign.
