BCV27 Description

Short technical summary and product information.

The BCV27 is an NPN Darlington transistor from On Semiconductor, designed for general-purpose switching and amplification applications. It features a maximum collector-emitter voltage of 30V and a continuous collector current rating of 1.2A, with a power dissipation of 350mW. The Darlington configuration provides a high DC current gain of at least 20,000 at 100mA collector current and 5V Vce, enabling high sensitivity in low-current drive circuits. The transistor offers a typical transition frequency of 220MHz, suitable for moderate-speed switching. The device is housed in a compact SOT-23-3 surface-mount package, also known as TO-236-3 or SC-59, making it ideal for space-constrained designs. It operates over a junction temperature range of -55°C to 150°C. The BCV27 is RoHS3 compliant and has a moisture sensitivity level of 1 (unlimited).
