PLA140
400V, 250mA Single-Pole Normally Open Relay
Description
The PLA140 is a single-pole normally open (1-Form-A) Solid State Relay that uses optically coupled MOSFET technology to provide 3750Vrms of input-to-output isolation.
MOSFET output switches, which use IXYS Integrated Circuits' patented OptoMOS architecture, are controlled by a highly efficient infrared LED.
The PLA140’s combination of low on-resistance and high load current handling makes it suitable for a variety of industrial applications.
Because Solid State Relays like the PLA140 have no moving parts, they offer faster, bounce-free switching in a more compact surface mount or though hole package than traditional electromechanical relays.

Absolute Maximum Ratings are stress ratings. Stresses in excess of these ratings can cause permanent damage to the device. Functional operation of the device at conditions beyond those indicated in the operational sections of this data sheet is not implied.
Typical values are characteristic of the device at +25°C, and are the result of engineering evaluations. They are provided for information purposes only, and are not part of the ma.
