onsemi Darlington Transistor NPN, 1.2 A, 30 V, hFE 4000, 3-Pin SOT-23 BCV27

onsemi BCV27 is a Darlington NPN transistor engineered for high gain and efficient performance in various electronic circuit applications. It features a maximum continuous collector current of 1.2 A and a maximum collector-emitter voltage rating of 30 V, ensuring reliable switching under moderate power conditions. The transistor is housed in a compact 3-pin SOT-23 surface mount package, ideal for space-constrained designs.

With a minimum DC current gain (hFE) of 4000, the BCV27 excels in amplification tasks requiring high gain figures. Its robust voltage ratings include a maximum collector-base voltage of 40 V and emitter-base voltage of 10 V, providing strong electrical endurance and protection against transient conditions.

The transistor's operating temperature range from -55°C up to 150°C enables use in harsh environmental conditions typical in industrial, automotive, and consumer electronics. The low maximum collector-emitter saturation voltage at 1 V helps minimize power dissipation, contributing to energy-efficient circuit designs.

The compact physical dimensions of 2.92 mm in length and 0.93 mm in height make it well-suited for dense printed circuit board layouts. Additionally, the very low maximum collector cut-off leakage current of 0.0001 mA reduces standby power consumption in sensitive electronic applications.
