## **Description** The CPC1540 is a normally open (1-Form-A) Solid State Relay with an integrated current limit feature that can replace electromechanical relays while enhancing the robustness of wireline-interface applications. Designed specifically to target the hook switch telephony market, the CPC1540 has a load voltage rating of 350V. The relay is constructed using an efficient infrared LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically isolated technology, comprises a photodiode array, switch control with active current limiting circuitry, and MOSFET switches. Active current-limit circuitry in the CPC1540 provides a thermal shutdown feature, offering excellent power-cross immunity for improved survivability in harsh environments. These enhancements greatly improve the robustness of end systems using this device compared to systems using relays without the integrated current limit. In addition, the active current limit circuitry enables the CPC1540 to pass FCC 68.302 and other regulatory voltage surge requirements when adequate overvoltage protection is provided. The CPC1540 relay may be used in both AC and DC applications. ## **Approvals** - UL Certified Component: File E76270 - CSA Certified Component: Certificate 1172007 - EN/IEC 60950-1 Certified Component: Certificate available on our website ## **Ordering Information** **Part # Description** CPC1540G 6-Pin DIP (50/Tube) CPC1540GS 6-Pin Surface Mount (50/Tube) ~~———~~ CPC1540GSTR 6-Pin Surface Mount, Tape & Reel (1000/Reel) **Switching Characteristics of Normally Open Devices** **==> picture [118 x 76] intentionally omitted <==** **----- Start of picture text -----**

For guaranteed parameters not indicated in the written specifications, please contact our application department. **www.ixysic.com** R04 **3** **CPC1540** INTEGRATED CIRCUITS DIVISION ## **Manufacturing Information** ## **Moisture Sensitivity** All plastic encapsulated semiconductor packages are susceptible to moisture ingression. IXYS Integrated Circuits classifies 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) classification 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 Moisture Sensitivity Level (MSL) Classifi cation** CPC1540G / CPC1540GS MSL 1 ~~—————E~~ ## **ESD Sensitivity** This product is **ESD Sensitive** , and should be handled according to the industry standard **JESD-625** . ## **Soldering Profile** Provided in the table below is the Classification Temperature (TC) of this product and the maximum dwell time the body temperature of this device may be (TC - 5)ºC or greater. The classification temperature sets the Maximum Body Temperature allowed for this device during lead-free reflow processes. For through-hole devices, and any other processes, the guidelines of **J-STD-020** must be observed. |**Device**

~~———~~|250ºC|30 seconds|1| |CPC1540GS
~~———~~|250ºC|30 seconds|3| ## **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 flux or solvents that are Chlorine- or Fluorine-based.
