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**

~~—E——————————~~||| *Total cumulative duration of all waves. ## **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** R12 **5** **PAA140** INTEGRATED CIRCUITS DIVISION ## **Mechanical Dimensions** ## **PAA140** ## **PAA140S** ## **PAA140P** 9.652 ± 0.381 7.620 ± 0.254 **PCB Hole Pattern** 2.540 ± 0.127 (0.380 ± 0.015) (0.300 ± 0.010) (0.100 ± 0.005) 8-0.762 DIA. 2.540 ± 0.127 ~~a~~ s ~~l~~ (8-0.030 DIA.)
