BSP52

The BSP52 is an NPN Darlington bipolar junction transistor manufactured by On Semiconductor. It is designed for general-purpose switching and amplification applications requiring high current gain. The transistor features a maximum collector-emitter voltage (VCEO) of 80V, a maximum collector current of 800mA, and a minimum DC current gain (hFE) of 2000 at 500mA and 10V. The maximum Vce saturation voltage is 1.3V at 500µA base current and 500mA collector current. The device can dissipate up to 1W of power and operates over a junction temperature range of -55°C to 150°C. The BSP52 is offered in a surface-mount SOT-223-4 package, which is also known as TO-261-4 or TO-261AA. The package is suitable for automated assembly and is commonly used in compact designs. The part is RoHS3 compliant and REACH unaffected, although these compliance claims are unverified. The BSP52 is available in tape and reel packaging from distributors such as Digi-Key, with part numbers BSP52TR-ND (tape and reel), BSP52CT-ND (cut tape), and BSP52DKR-ND (Digi-Reel).
