STT818B Description

Short technical summary and product information.

The STT818B is a PNP bipolar junction transistor designed for general purpose switching and amplification applications. It offers a maximum collector-emitter voltage of 30V and a continuous collector current rating of 3A. The device has a minimum DC current gain (hFE) of 100 at 500mA collector current and 1V VCE, and a low VCE saturation voltage of 500mV at 2A collector current. With a maximum power dissipation of 1.2W, it is suitable for moderate power applications. The transistor is housed in a compact SOT-23-6L surface mount package, making it ideal for space-constrained designs. The operating junction temperature range extends up to 150°C. This component is RoHS3 compliant and has an MSL of 1 (unlimited).
