VISHAY BPV11 Clear Silicon NPN Phototransistor T1 3/4 5mm

The VISHAY BPV11 is a high-performance clear silicon NPN phototransistor designed for a wide range of light-sensing applications. It features high radiant sensitivity and is responsive to both visible and near-infrared radiation, making it a versatile component for various electronic circuits.

This device boasts exceptionally fast response times, enabling it to detect rapid changes in light levels with precision. A key feature is the accessible base terminal, which provides greater control over the switching characteristics, allowing for more nuanced circuit design compared to standard two-lead phototransistors.

With a narrow ±15° angle of half sensitivity, the BPV11 offers a more directional field of view, which is ideal for applications requiring targeted sensing and reduced interference from ambient light sources. Its compact T-1 3/4 (5mm) case style ensures it can be integrated into space-constrained designs.
