BCX70J Description

Short technical summary and product information.

The BCX70J series from Philips Semiconductors comprises NPN general purpose transistors in a SOT-23 plastic package. These transistors are suitable for general purpose switching and amplification tasks.

Key electrical characteristics include a maximum collector-emitter voltage (VCEO) of 45 V and a continuous collector current (IC) of 100 mA. The DC current gain (hFE) varies depending on the specific variant and operating conditions, with values ranging from 120-220 at 2 mA collector current for the BCX70G, up to 380-630 for the BCX70K under the same conditions. Saturation voltages (VCEsat and VBEsat) are also specified at various current levels.

Thermal performance is managed by a total power dissipation of 250 mW at an ambient temperature of 25 °C, with a thermal resistance from junction to ambient of 500 K/W when mounted on an FR4 printed-circuit board. The operating and storage temperatures range from -65 °C to +150 °C.

This transistor is housed in a compact SOT-23 surface-mount package, making it suitable for space-constrained applications. PNP complements are available in the BCX71 series.
