Surface Mount 30,000 Watt Transient Voltage Suppressor


These high power 30 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 14 volts to 400 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 brochure on our web site for more
   details on the screening options.
• Suppresses transients up to 30,000 W @ 10/1000 μs (see Figure 1)
• Moisture classification is Level 1 with no dry pack required per IPC/JEDEC J-STD-020B
• RoHS compliant versions are available
• 3σ lot norm screening performed on standby current (ID)

• Protection from switching transients and induced RFI
• Protection from ESD, and EFT per IEC 61000-4-2 and IEC 61000-4-4
• Secondary lightning protection per IEC 61000-4-5 with 42 ohms source impedance:
   Class 1,2,3,4,5: MPLAD30KP14A to 400CA
   Class 5: MPLAD30KP14A to 400CA (short distance)
   Class 5: MPLAD30KP14A to 220CA (long distance)
• Secondary lightning protection per IEC 61000-4-5 with 12 ohms source impedance:
   Class 1,2,3: MPLAD30KP14A to 400CA
   Class 4: MPLAD30KP14A to 220CA
• Secondary lightning protection per IEC 61000-4-5 with 2 ohms source impedance:
   Class 2: MPLAD30KP10A to 400CA
   Class 3: MPLAD30KP14A to 220CA
   Class 4: MPLAD30KP14A to 110CA
• Pin injection protection per RTCA/DO-160F for Waveform 4 (6.4/69 μs @ 25°C)*:
   Level 4: MPLAD30KP14A to 400CA
   Level 5: MPLAD30KP14A to 260CA
• Pin injection protection per RTCA/DO-160F for Waveform 5A (40/120 μs @25°C)*:
   Level 4: MPLAD30KP14A to 64CA
   Level 5: MPLAD30KP14A to 26CA
