The SDT400 consists of a phototransistor optically coupled
to a light emitting diode. Optical coupling between the
input IR LED and output phototransistor allows for high
isolation levels while maintaining low-level DC signal
control capability. The SDT400 provides an optically
isolated method of controlling many interface applications
such as telecommunications, industrial control and
instrumentation circuitry.
VCEO = 60V / 70V / 80V
Small 4 pin DIP/SMD package
Low input power consumption
High stability
CTR Range 50 – 600%
High Isolation Voltage (5000VRMS)
Long Life / High Reliability
RoHS / Pb-Free / REACH Compliant
The SDT400 comes standard in a miniature 4 pin DIP
package.
