**CPC1966Y 600V, 3Arms AC Power Switch** INTEGRATED CIRCUITS DIVISION **Parameter Rating Units** AC Operating Voltage 20 - 240 Vrms Load Current 3 Arms On-State Voltage Drop 0.8 Vrms (at IL = 3Arms) ~~———~~ Blocking Voltage 600 VP ## **Features** - Load Current up to 3Arms - 600VP Blocking Voltage - 5mA Sensitivity - Zero-Crossing Detection - DC Control, AC Output - Optically Isolated - Low EMI and RFI Generation - High Noise Immunity - Flammability Rating UL 94 V-0 ## **Description** CPC1966Y is an AC Solid State Switch utilizing dual power SCR outputs. This device also includes zero-cross turn-on circuitry, and is specified with a blocking voltage of 600VP . In addition, the tightly controlled zero-cross circuitry ensures low noise switching of AC loads by minimizing the generation of transients. The optically coupled input and output circuits provide 3750Vrms of isolation and noise immunity between the control and load circuits. As a result, the CPC1966Y is well suited for industrial environments where electromagnetic interference would disrupt the operation of plant facility communication and control systems. ## **Approvals** ## **Applications** - Programmable Control - UL Recognized Component: File E69938 - CSA Certified Component: File 1172007 - Process Control - Power Control Panels - Remote Switching - Gas Pump Electronics - Contactors - Large Relays - Solenoids - Motors - Heaters ## **Ordering Information** **==> picture [238 x 165] intentionally omitted <==** **----- Start of picture text -----**<br> Part # Description<br>E—EE=-~ CPC1966Y 4-Pin (8-Pin Body) Power SIP Package(25/Tube)<br>Pin Configuration<br>ZC<br>1 2 3 4<br>– LED + LED AC Load AC Load<br>**----- End of picture text -----**<br> ## **Pin Configuration** **1** DS-CPC1966-R06 **www.ixysic.com** **CPC1966Y** INTEGRATED CIRCUITS DIVISION ## **Absolute Maximum Ratings @ 25ºC** |**Parameter**|**Ratings**|**Units**| |---|---|---| |BlockingVoltage(VDRM)|600|VP| |Reverse Input Voltage|5|V| |Input Control Current<br>Peak(10ms)|50|mA| ||1|A| |Input Power Dissipation1|150|mW| |Total Power Dissipation2|2400|mW| |Isolation Voltage, Input to Output|3750|Vrms| |Operational Temperature, Ambient|-40 to +85|°C| |Storage Temperature|-40 to +125|°C| _Absolute Maximum Ratings are stress ratings.

The body temperature of the device must not exceed the Maximum Body Temperature shown below at any time during the soldering process. **Device Maximum Solder Temperature Maximum Body Temperature Maximum Total Dwell Time Wave Cycles** CPC1966Y 260ºC 245ºC 10 seconds 1 ~~—————————~~ ## **Board Wash** IXYS Integrated Circuits recommends the use of no-clean flux formulations. Board washing to reduce or remove flux residue following the solder reflow process is acceptable provided proper precautions are taken to prevent damage to the device. These precautions include but are not limited to: using a low pressure wash and providing a follow up bake cycle sufficient to remove any moisture trapped within the device due to the washing process. Due to the variability of the wash parameters used to clean the board, determination of the bake temperature and duration necessary to remove the moisture trapped within the package is the responsibility of the user (assembler). Cleaning or drying methods that employ ultrasonic energy may damage the device and should not be used. Additionally, the device must not be exposed to halide flux or solvents. **www.ixysic.com** R06 **5** **CPC1966Y** INTEGRATED CIRCUITS DIVISION ## **MECHANICAL DIMENSIONS** ## **CPC1966Y** **==> picture [461 x 210] intentionally omitted <==** **----- Start of picture text -----**<br> (0.830±0.015)21.082±0.381 3.302±0.051 PCB Hole Pattern<br>(0.130±0.002)<br>1.150 DIA. x4<br>_ aa (0.069)1.75 (0.045 DIA. x4)<br>10.160±0.127<br>(0.400±0.005) 7º TYP<br>4 Places<br>5.080<br>(0.200)<br>Pin 1<br>1.016±0.127 10.160<br>Pin 1<br>(0.040±0.005) (0.400)<br>1.778<br>— (0.070) _ 4.572±0.127 . ; 2.540<br>(0.180±0.005)<br>i c 0.381±0.013 o H (jms (0.100)<br>0.762±0.076 10.160±0.127 (0.015±0.0005)<br>(0.030±0.003) (0.400±0.005) 1.651±0.102<br>2.540±0.12 7 5.080±0.127 (0.065±0.004) 1.778<br>(0.100±0.005) Pou (0.200±0.005) r (0.070) 4<br>7º TYP<br>4 Places<br>Note: Pin-to-pin tolerances are non-cumulative.<br>Dimensions<br>mm<br>—| _ (inches)<br>**----- End of picture text -----**<br> ## **For additional information please visit our website at: https://www.ixysic.com** **Disclaimer Notice - Information furnished is believed to be accurate and reliable.
