NEXPERIA BC846,215 NPN General-Purpose SMD Transistor SOT-23

The NEXPERIA BC846,215 is a general-purpose NPN bipolar junction transistor (BJT) housed in a compact SOT-23 surface-mount package. Designed for a wide array of electronic applications, this component is an excellent choice for both switching and amplification circuits where reliability and small form factor are key.

This transistor is characterised by its robust performance specifications, including a maximum collector-emitter voltage (Vceo) of 65V and a continuous collector current (Ic) of 100mA. With a power dissipation rating of 250mW, it is well-suited for low to medium-power designs. The device operates effectively across a broad ambient temperature range from -65°C to +150°C, ensuring stability in various environmental conditions.

Key Features & Applications

Featuring a transition frequency (ft) of 100MHz, the BC846,215 offers good high-frequency performance for amplification tasks. Its DC current gain (hFE) is specified at a minimum of 110, providing consistent signal amplification. The small SMD footprint makes it ideal for modern, space-constrained PCB designs, from consumer electronics to industrial control systems.

Common uses include signal amplification in audio pre-amplifiers, driver stages for LEDs or relays, and as a switch in digital logic interfaces. Its general-purpose nature makes it a versatile and reliable component for prototyping, hobbyist projects, and volume production alike. The product is supplied in a standard SOT-23 (TO236AB) plastic package with three pins for easy surface-mount assembly.
