Product details
Overview
MADA3KP8.0CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in industrial and aerospace systems. It features a 8.0 V reverse standoff voltage (VWM), 8.89–9.83 V breakdown voltage (V(BR)), 13.6 V maximum clamping voltage at 220.6 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MADA3KP8.0CA datasheet, MADA3KP8.0CA pinout, MADA3KP8.0CA application, or MADA3KP8.0CA equivalent, this device serves as a critical secondary lightning protection component per IEC61000-4-5 (with 2 Ω, 12 Ω, and 42 Ω source impedances), ESD suppression per IEC61000-4-2, and EFT mitigation per IEC61000-4-4 in power supply and signal line interfaces.
Technical Context
The MADA3KP8.0CA is a surface-mount, void-free epoxy-packaged TVS array with bidirectional polarity indicated by the "C" suffix. Its sub-100 ps response time enables effective suppression of fast transients including ESD and switching spikes.
It delivers 3000 W peak pulse power at 10/1000 µs waveform, with clamping performance validated up to 220.6 A IPP and thermal derating defined per Figure 3. Polarity follows standard convention: odd-numbered pins are cathodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA | 600 W PPP rating, same VWM and bidirectional polarity, smaller SMB package | Limited to Class 2 lightning protection; unsuitable for 3000 W surge events | Select when space-constrained PCB layout prioritizes footprint over energy handling |
| SMCJ8.0CA | 1500 W PPP rating, identical VWM and package outline but lower clamping robustness | Meets IEC61000-4-5 Class 3 only; requires parallel staging for Class 4 compliance | Choose where cost reduction is critical and peak surge duty cycle remains below 0.05% |
Compared with SMBJ8.0CA and SMCJ8.0CA, the MADA3KP8.0CA provides triple the peak pulse power handling and direct Class 4 lightning compliance without staging-enabling single-device protection for mission-critical 28 V and 48 V systems.

FAQ
What is the clamping voltage of the MADA3KP8.0CA under maximum rated surge current?
The MADA3KP8.0CA exhibits a maximum clamping voltage (VC) of 13.6 V at its rated peak pulse current (IPP) of 220.6 A under 10/1000 µs waveform conditions. This value is measured per Figure 2 in RF01243 Rev B and ensures downstream components experience controlled overvoltage during worst-case transients.
Is the MADA3KP8.0CA RoHS compliant?
Yes, the MADA3KP8.0CA is RoHS compliant, indicated by the "e3" suffix in its full marking per RF01243 Rev B Page 2. The device uses annealed matte-tin plating and void-free thermosetting epoxy meeting UL94V-0, with no lead or restricted substances above threshold limits.
How does the bidirectional design of the MADA3KP8.0CA affect its circuit placement?
The bidirectional design of the MADA3KP8.0CA allows it to be placed directly across any two nodes requiring symmetrical overvoltage protection-such as power-to-ground or differential signal pairs-without polarity orientation concerns. Pin 1 (cathode) and Pin 2 (anode) form a reversible clamp path.
Can the MADA3KP8.0CA be used for primary lightning protection?
No, the MADA3KP8.0CA is specified for secondary lightning protection per IEC61000-4-5 only. It is not rated for direct strike exposure or primary protection zones. Its 3000 W rating applies to coupled surges with defined source impedances (2 Ω, 12 Ω, 42 Ω), not open-circuit lightning currents.
What is the maximum operating temperature range for the MADA3KP8.0CA?
The MADA3KP8.0CA supports a junction and storage temperature range of –55 °C to +150 °C, as confirmed in the Maximum Ratings table on RF01243 Rev B Page 2. This enables deployment in extended-environment applications including engine compartments and avionics bays.
