This datasheet introduces the features, applications and specifications of Philips Semiconductors BAT721 series Schottky diodes.
The BAT721 series are planar Schottky barrier diodes offered by Philips Semiconductors in a compact SOT23 surface‑mount package. They are available as single and double diodes with various pin configurations for high‑speed switching and voltage‑clamping applications.
Key specifications include a 40 V continuous reverse voltage, 200 mA continuous forward current, and low forward voltage drop (300 mV at 10 mA). The devices are rated for storage temperatures from –65 °C to +150 °C and feature a thermal resistance of 500 K/W. They are not intended for life‑support equipment.
