RON = 1.0 TYP
• LARGE CONTINUOUS LOAD CURRENT:
IL = 400 mA
• 1 CHANNEL TYPE:
1a output
• DESIGNED FOR AC/DC SWITCHING LINE CHANGER
• SMALL AND THIN PACKAGE:
4 pin SOP, Height = 2.1 mm
• HIGH ISOLATION VOLTAGE:

DESCRIPTION
The PS7214-1A is a low on-state resistance solid state relay
containing GaAs LEDs on the light emitting side (input side)
and MOS FETs on the output side.
It is suitable for PLC, etc. because of its large continuous load
current and low on-state resistance.
APPLICATIONS
• MEASUREMENT EQUIPMENT
• FA EQUIPMENT
