This device features Rapid Turn-On (non-zero-cross) control of the output SCRs, which makes it ideal for precisely switching AC loads independent of the load voltage phase. The optically coupled input and output circuits provide 3750Vrms of isolation and noise immunity between the control and load circuits. As a result, the CPC1966YX6 is well suited for industrial environments where electromagnetic interference would disrupt the operation of plant facility communication and control systems. ## **Approvals** - UL Recognized Component: File E69938 - CSA Certified Component: Certificate 1172007 - High Noise Immunity - Machine Insertable, Wave Solderable ## **Applications** - Lighting - HVAC (Heating, Ventilation, Air Conditioning) - Programmable Control - Process Control - Power Control Panels - Remote Switching - Gas Pump Electronics - Contactors - Large Relays - Solenoids - Motors - Heaters ## **Ordering Information** **==> picture [240 x 163] intentionally omitted <==** **----- Start of picture text -----**<br> Part # Description<br>CPC1966YX6 4-Pin (8-Pin Body) SIP (25/Tube)<br>—eEeEsn ee<br>Pin Configuration<br>R<br>1 2 3 4<br>– LED + LED AC Load AC Load<br>**----- End of picture text -----**<br> **Rapid Turn-On (Non-Zero-Cross) Waveforms** **==> picture [31 x 128] intentionally omitted <==** **----- Start of picture text -----**<br> Control<br>AC Load<br>Voltage<br>Load<br>Current<br>Voltage<br>Across<br>Relay<br>**----- End of picture text -----**<br> DS-CPC1966YX6-R01 **1** **www.ixysic.com** **CPC1966YX6** INTEGRATED CIRCUITS DIVISION ## **Absolute Maximum Ratings @ 25ºC** |**Parameter**|**Ratings**|**Units**| |---|---|---| |Blocking Voltage (VDRM)|600|VP| |Reverse Input Voltage|5|V| |Input Control Current<br>Peak (10ms)|50|mA| ||1|A| |di/dt Critical Rate of Rise<br>of On-State Current|75|A/s| |Input Power Dissipation1|150|mW| |Total Power Dissipation2|2400|mW| |ESD, Human Body Model|4|kV| |i2t Fusing Current (1/2 Sine Wave, 60Hz)|8|A2s| |Isolation Voltage, Input to Output|3750|Vrms| |Operational Temperature|-40 to +85|°C| |Storage Temperature|-40 to +125|°C| _Absolute Maximum Ratings are stress ratings.

R01 **www.ixysic.com** **4** **CPC1966YX6** INTEGRATED CIRCUITS DIVISION ## **Manufacturing Information** ## **Moisture Sensitivity** All plastic encapsulated semiconductor packages are susceptible to moisture ingression. IXYS Integrated Circuits Division classified all of its plastic encapsulated devices for moisture sensitivity according to the latest version of the joint industry standard, **IPC/JEDEC J-STD-020** , in force at the time of product evaluation. We test all of our products to the maximum conditions set forth in the standard, and guarantee proper operation of our devices when handled according to the limitations and information in that standard as well as to any limitations set forth in the information or standards referenced below. Failure to adhere to the warnings or limitations as established by the listed specifications could result in reduced product performance, reduction of operable life, and/or reduction of overall reliability. This product carries a **Moisture Sensitivity Level (MSL) rating** as shown below, and should be handled according to the requirements of the latest version of the joint industry standard **IPC/JEDEC J-STD-033** . |**Device**<br>~~————————~~|**Moisture Sensitivity Level (MSL) Rating**<br>~~————————~~| |---|---| |CPC1966YX6<br>~~————————~~|MSL 1<br>~~————————~~| ## **ESD Sensitivity** This product is **ESD Sensitive** , and should be handled according to the industry standard **JESD-625** . ## **Reflow Profile** This product has a maximum body temperature and time rating as shown below. All other guidelines of **J-STD-020** must be observed. **Device Maximum Temperature x Time** CPC1966YX6 245ºC for 30 seconds ~~————~~ ## **Board Wash** IXYS Integrated Circuits Division recommends the use of no-clean flux formulations. However, board washing to remove flux residue is acceptable. Since IXYS Integrated Circuits Division employs the use of silicone coating as an optical waveguide in many of its optically isolated products, the use of a short drying bake could be necessary if a wash is used after solder reflow processes. Chlorine- or Fluorine-based solvents or fluxes should not be used. Cleaning methods that employ ultrasonic energy should not be used.
