Excelitas VTP Series Silicon Photodiodes
PART/ VTP1232H

VTP1232H - Si PD, T1 3/4 Lensed, 2.326mm2

The VTP1232H is a silicon photodiode in a clear end-looking T1¾ lensed package with an enhanced response in the visible and near IR spectral range. This photodiode exhibits a very high shunt resistance, low dark current and low capacitance.

This fast response silicon photodiode provides a 2.326 mm2 active area and is designed for a spectral response between 400 nm and 1100 nm.

This series of photodiodes is designed for low-junction capacitance to achieve fast response times and can be operated under reverse bias to decrease the capacitance in order to further increase the speed of response. These photodiodes can also be operated in photovoltaic mode if speed of response is not critical for the application in which they are being used.

These photodiodes have excellent response in the IR spectral range and are well matched to the Excelitas Infrared LED VTE Series.
