Data Sheet

ET0415

.040 x .040 Phototransistor Low-High Gain

FEATURES

Spectrally matched to GaAs and GaAlAs emitters
Large photosensitive area
High sensitivity
Collector voltage to 30V

DESCRIPTION

The ET0415 phototransistor is fabricated using silicon planar diffused technology. The die is silicon nitride passivated for reliability, and anti-reflection coated to enhance light absorption. Standard thickness is 15 mils. Die can be probed to special beta requirements, and sawed in various array configurations. Applications include optical encoders and industrial controls.

NOTES:

This value is very dependent on the thermal impedance of subsequent packaging techniques.
For test, base current is forced at base pad rather than created by illumination.
These values are typical for the process and are not tested.
