A recommended PCB layout for the SS26SHE3/61T includes a ground plane under the photodiode, a small pad for the anode, and a larger pad for the cathode. This layout helps to reduce noise and improve signal integrity.
The SS26SHE3/61T's responsivity and dark current are temperature-dependent. To minimize temperature effects, use a thermally stable PCB material, ensure good thermal conduction to the ambient environment, and consider using a temperature compensation circuit or algorithm in your design.
While the datasheet specifies a maximum reverse voltage of 100 V, it's recommended to operate the SS26SHE3/61T between 5 V to 20 V to ensure optimal performance and minimize noise. Higher voltages may lead to increased dark current and reduced responsivity.
To protect the SS26SHE3/61T from ESD, use proper handling and storage procedures, such as using anti-static bags or wrist straps. In your design, consider adding ESD protection circuits, such as TVS diodes or resistors, to prevent damage from static electricity.
Vishay recommends a soldering profile with a peak temperature of 260°C (500°F) for a maximum of 10 seconds. Ensure that your soldering process meets these specifications to prevent damage to the photodiode.
