MICROCHIP MAPLAD18KP54CA

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 (VW M) of 7 volts to 200 volts in either unidirectional or bidirectional construction.

• 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 for more details on the screening options.
