NPN Bipolar BJT Single Transistor 45V 500mA 310mW SOT-23 SMD
Diodes Inc NPN general-purpose BJT transistor. 45V, 500mA, 310mW in a SOT-23 SMD package. Ideal for switching and amplification.
This NPN Bipolar (BJT) Single Transistor is a general-purpose semiconductor device housed in a small SOT-23 (TO-236AB) Surface-Mounted Device (SMD) plastic package. Designed for reliable switching and amplification, it offers a collector-emitter voltage of 45V and a continuous collector current of 500mA at an ambient temperature of 25°C. Additionally, it can handle a peak collector current of 1A for single pulses of up to 1ms.
Featuring a DC current gain (hFE) of up to 400, this transistor ensures efficient performance in low-power electronic circuits. The device operates effectively across a wide temperature range, from -65°C to 150°C, making it suitable for demanding environments. It boasts a power dissipation of 310mW and comes in a compact 3-pin configuration for straightforward surface-mount assembly.
