Silicon photodiode VTB6061CIEH

Description
The VTB6061CIEH is a silicon photodiode in a hermetic TO-8 flat-window package with an integrated visible filter that closely matches the human eye photopic response. It provides a large 37.7 mm² active area, very high shunt resistance and very low dark current, making it suitable for precision light measurement in photovoltaic mode or with a small reverse bias.

General
The VTB6061CIEH features a 37.7 mm² active area optimized for photometric applications. It is primarily intended for photovoltaic operation but can be used with a small reverse bias. The device's high shunt resistance minimizes offset errors in high-gain trans-impedance amplifier circuits.
