Excelitas’ VTD Series of industry standard silicon photodiodes consists of planar silicon photodiodes in an infrared transmitting, visible-blocking molded plastic package. All VTD Series silicon photodiodes exhibit low dark current under reverse bias, fast speed of response and a wide field of view.

These photodiodes have been commonly used in many applications as a replacement for competitive devices.

The VTD34 series in plastic packages (partly surface-mount) are BPW34(F) industry equivalents and provide excellent sensitivity at low light level. These photodiodes with 7.45 mm² active area are designed for a spectral response between 400 nm and 1100 nm or 725 nm and 1150 nm. Suitable for direct mounting to a printed circuit board (PCB), arrays can be formed by positioning these devices side by side.

The VTD31AAH is a silicon photodiode on ceramic substrate coated with clear epoxy, and a CLD31AA industry equivalent. This photodiode provides a low dark current, fast response and wide field-of-view. This silicon photodiode provides a 16.73 mm² active area designed for spectral response between 400 nm and 1150 nm.

The VTD205 series are silicon photodiodes in TO-92 side-looker package, clear (VTD205KH) or with visible blocking (VTD205H), and an SFH205(K) industry equivalent. This photodiode series provides a 7.41 mm2 active area, low dark current, fast response, and a wide field-of-view. The devices are designed for spectral response between 800 nm and 1100 nm (VTD205H) or between 400 nm and 1100 nm (VTD205KH).

The VTD206 series are silicon photodiodes in TO-92 side-looker package, clear (VTD206KH) or with visible blocking (VTD206H), and an SFH206(K) industry equivalent. This photodiode series provides a 7.41 mm2 active area, low dark current, fast response, and a wide field-of-view. The devices are designed for spectral response between 750 nm and 1100 nm (VTD206H) or between 400 nm and 1100 nm (VTD206KH).
