KAQY212 Series
4PIN 60V N.O TYPE
SOLID STATE RELAY-MOSFET OUTPUT
Description
The KAQY212 series is robust, ideal for telecom and
ground fault applications. It is a SPST normally open switch (1
Form A) that replaces electromechanical relays in many
applications. It is constructed using a GaAlAs LED for
actuation control and an integrated monolithic die for the
switch output. The die, fabricated in a high-voltage
dielectrically isolated technology, is comprised of a
photodiode array, switch control circuitry and MOSFET
switches.
Features
1. Normally open, single pole single throw
2. Control 60V AC or DC voltage
3. Switch 400mA loads
4. Controls low-level analog signals
5. High sensitivity, low ON resistance
6. Low-level off-state leakage current
7. High isolation voltage 5KV (DIP / SMD)
8. Pb free and RoHS compliant
9. MSL class 1
10. Agency Approvals:
• UL Approved (No. E108430): UL508
• C-UL Approved (No. E108430)
• FIMKO Approved: EN60065, EN60950
Application
• Telecommunications (PC, electronic notepad)
• Modem
• Telephone equipment
• Security equipment
• Sensors
• Measuring and testing equipment
• Factory automation equipment
• High speed inspection machines
