MPLAD18KP160CA Microchip

Surface Mount 18,000 W Transient Voltage Suppressor Datasheet 1 Product Overview These high-power, 18 kW-rated transient voltage suppressors in a surface-mount package are provided with design features to minimize thermal resistance and cumulative heating. Typical applications include lightning and automotive load dump protection. They are particularly effective at meeting the multi- stroke lightning standard RTCA DO-160, section 22 for aircraft design. This efficient low-profile package design is offered in standoff voltage selections (VWM) of 7 V to 200 V in either unidirectional or bidirectional construction. 1.1 Features The following are key features of the MPLAD18KP7.0AMPLAD18KP200CA devices: Available in both unidirectional and bidirectional construction (bidirectional with CA suffix) High reliability with wafer fabrication and assembly lot traceability All parts surge tested Low-profile surface mount package Optional upscreening is available with various screening and conformance inspection options based on MIL-PRF-19500. Refer to Hirel Non-Hermetic Product Portfolio brochure on our website for more details on the screening options. Suppresses transients up to 18,000 W at 10/1000 s (see Peak Pulse Power vs. Pulse Time (see page 6)) Moisture classification is Level 1 with no dry pack required per IPC/JEDEC J-STD-020B RoHS-compliant versions are available 3 lot norm screening performed on standby current (ID) AEC-Q101 qualified 1.2 Applications and Benefits The following are benefits of the MPLAD18KP7.0AMPLAD18KP200CA devices: Protection from switching transients and induced RFI Protection from electrostatic discharge (ESD) and electrical fast transient (EFT) per IEC 61000-4-2 and IEC 61000-4-4 Secondary lightning protection per IEC 61000-4-5 with 42 source impedance: Class 1,2,3,4,5: MPLAD18KP7.0A to 200CA Secondary lightning protection per IEC 61000-4-5 with 12 source impedance: Class 1,2,3,4: MPLAD18KP7.0A to 200CA Secondary lightning protection per IEC 61000-4-5 with 2 source impedance: Class 4: MPLAD18KP5.0 to 64CA 1 Pin injection protection per RTCA/DO-160G for Waveform 4 (6.4/69 s at 25 C) : Level 4: MPLAD18KP7.0A to 200CA Level 5: MPLAD18KP7.0A to 130CA 1 Pin injection protection per RTCA/DO-160G for Waveform 5A (40/120 s at 25 C) : Level 4: MPLAD18KP7.0A to 36CA Notes: 1.

Table 2 Symbols and Definitions Symbol Value Definition I(BR) Breakdown current The current used for measuring breakdown voltage V(BR). ID Standby current The current through the device at rated stand-off voltage. IPP Peak Impulse current The maximum-rated random recurring peak impulse current or nonrepetitive peak impulse current that may be applied to a device. A random recurring or nonrepetitive transient current is usually due to an external cause, and it is assumed that its effect will have completely disappeared before the next transient arrives. V(BR) Breakdown voltage The voltage across the device at a specified current I(BR) in the breakdown region. VC Clamping voltage The voltage across the device in a region of low differential resistance during the application of an impulse current (IPP) for a specified waveform. VWM Working standoff voltage The maximum-rated value of dc or repetitive peak positive cathode- to-anode voltage that may be continuously applied over the standard operating temperature. V(BR) Temperature coefficient of breakdown The change in breakdown voltage divided by the change in voltage temperature that caused it expressed in %/C or mV/C.
