LDA201STR Description

Short technical summary and product information.

The CP Clare LDA201STR is a dual optocoupler designed for various applications including telecom switching, modem switching, and current sensing. It features a single or Darlington transistor output with bi-directional or uni-directional input options.

 

Key electrical specifications include a phototransistor blocking voltage of up to 50V and an input-to-output isolation voltage of 3750V RMS. The current transfer ratio (CTR) ranges from 33% to 1000% at a typical forward current of 6mA. The input voltage drop is typically 1.2V at 5mA, and the input control current is 6mA.

 

This optocoupler is available in a small 8-pin DIP package, suitable for through-hole mounting. It has a continuous load rating of 100mA and operates within an ambient temperature range of -40°C to +85°C. The device is also machine insertable and wave solderable.

 

Approvals include UL Recognition (File E76270), CSA Certification (File LR 43639-10), and BSI Certification for BS EN 60950 and BS EN 41003 standards.
