SD5620

The SD5620/5630 series is a family of single chip Optoschmitt IC detectors mounted in a TO-46 metal can package. The photodetector consists of a photodiode, amplifier, voltage regulator, Schmitt trigger and an NPN output transistor with 10 kOhm (nominal) pull-up resistor. Output rise and fall times are independent of the rate of change of incident light. Detector sensitivity has been internally temperature compensated. The TO-46 package is ideally suited for operating in hostile environments.

Device Polarity

• Buffer: Output is HI when incident light intensity is above the turn-on threshold level
• Inverter: Output is LO when incident light intensity is above the turn-on threshold level
