Overview
Our Fast-Response Silicon Photodiodes offer low-junction capacitance to achieve fast response times. They can be operated under reverse bias to decrease the capacitance and further increase the speed of response or in photovoltaic mode in applications where speed of response is not critical. With excellent response in the IR-spectral range, these devices are well-matched to Excelitas' Infrared LED VTE Series.

Product family

• VTP1232FH - Si PD, T1 3/4 Flat, 2.326 mm2: The VTP1232FH is a silicon photodiode in a clear end-looking T1¾ flat package. This photodiode provides an enhanced response in the visible and near IR spectral range, and exhibits a very high shunt resistance, low dark current and low capacitance.
