Excelitas VTP Series Silicon Photodiodes
PART/ VTP3420LA

VTP3420LA - T-1 Lensed IRT, 1.64mm2

The VTP3420LA is a silicon photodiode in a visible-blocking end-looking, long T1 lensed package with an enhanced response in the 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 1.64 mm2 active area and is designed for a spectral response between 700 nm and 1150 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 in applications where speed of response is not critical.

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