BC817-40,215

A small giant – the BC817-40,215 bipolar transistor

Seemingly unassuming, the BC817-40,215 in a SOT-23 package is an NPN bipolar transistor that, thanks to its reliability and high current gain (250–600), performs excellently in amplifier circuits, low-power switches, and digital devices. With a maximum collector-emitter voltage of 45 V and a collector current of 0.5 A (up to 1 A pulse), it’s a versatile choice for professionals.

Compact and efficient – a bipolar transistor for special tasks

This model from Nexperia is made for those who don’t accept compromises. Thanks to its transition frequency of 100 MHz and power dissipation of 345 mW, it fits perfectly in SMD applications, especially where reliability and stable performance are essential. Typical uses? Signal amplifiers, control circuits, and transistor logic. If you're designing a device meant to last for years – this is a solid choice.
