KAQY216 Series

4PIN 600V N.O TYPE

SOLID STATE RELAY-MOSFET OUTPUT

Description 

The KAQY216 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 600V AC or DC voltage 

3. Switch 120mA 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. E169586): UL1577
