Product details
Overview
MXDA3KP9.0CA 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 9.0 V reverse standoff voltage (VWM), 10.0–11.1 V breakdown voltage (V(BR)), 15.4 V maximum clamping voltage at 194.8 A peak pulse current, and operates from –55 °C to +150 °C. It protects against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5) with 12 Ω and 2 Ω source impedances.
For engineers reviewing the MXDA3KP9.0CA datasheet, MXDA3KP9.0CA pinout, MXDA3KP9.0CA application, or MXDA3KP9.0CA equivalent, this page delivers verified electrical parameters, bidirectional polarity mapping, IEC61000-4-5 class compliance details, package dimensions, and traceable alternatives for high-reliability surge protection design.
Technical Context
The MXDA3KP9.0CA implements a monolithic silicon avalanche diode structure optimized for sub-nanosecond response (<5 ns) under bidirectional transient stress. Its clamping behavior is characterized at 10/1000 μs waveform with 3000 W peak pulse power rating and 194.8 A IPP, validated per MIL-PRF-19500 screening options when upscreened.
It supports secondary lightning protection across IEC61000-4-5 Class 1–3 with 12 Ω source impedance and Class 4 with 2 Ω source impedance. Standby leakage ID is ≤10 μA at 9.0 V VWM, and thermal derating follows Figure 3 down to zero power at +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum continuous operating voltage before clamping begins; matches 9 V rail systems. |
| V(BR) min/max | 10.0–11.1 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on margin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0CA | 600 W PPP rating, 10.0 V VWM, 15.4 V VC @ 38.8 A IPP - lower surge capacity. | Targeted at consumer-grade or non-safety-critical interfaces where 3000 W is not required. | Select SMBJ9.0CA only if system-level surge testing does not exceed IEC61000-4-5 Class 2 with 42 Ω source. |
| SMCJ9.0CA | 1500 W PPP rating, 9.0 V VWM, 15.4 V VC @ 97.4 A IPP - mid-tier power handling. | Suitable for automotive body electronics or industrial PLC I/O modules with moderate surge exposure. | Choose SMCJ9.0CA when footprint constraints prevent use of larger MDA package but 3000 W is unnecessary. |
Compared with MXDA3KP9.0CA, SMBJ9.0CA offers smaller size but one-fifth the surge energy absorption, while SMCJ9.0CA provides half the PPP and requires PCB area between SMB and MDA footprints - making MXDA3KP9.0CA essential for full IEC61000-4-5 Class 4 compliance in safety-critical infrastructure.

FAQ
What is the clamping voltage of MXDA3KP9.0CA at its rated peak pulse current?
The MXDA3KP9.0CA has a maximum clamping voltage (VC) of 15.4 V at its rated peak pulse current (IPP) of 194.8 A under 10/1000 μs waveform conditions. This value is measured per standard test methods defined in the datasheet and ensures downstream circuitry remains below safe voltage thresholds during surge events. The MXDA3KP9.0CA maintains this clamping performance across its full operating temperature range.
Is MXDA3KP9.0CA RoHS compliant?
Yes, MXDA3KP9.0CA is RoHS compliant, indicated by the "e3" suffix in its full part marking per Microsemi's nomenclature guide. The device uses annealed matte-tin plating and meets lead-free soldering requirements up to 260 °C for 10 seconds. Compliance is verified per JEDEC J-STD-609 and documented in Microsemi's material declarations for the MDA3KP family.
How does the bidirectional configuration of MXDA3KP9.0CA affect its circuit placement?
The bidirectional configuration of MXDA3KP9.0CA allows it to protect AC-coupled or floating signal paths without regard to polarity - each channel functions as a back-to-back diode pair. In practice, this means Pin 1 and Pin 3 connect to protected lines (e.g., differential bus pairs), while Pins 2 and 4 tie to a common reference plane. The MXDA3KP9.0CA thus eliminates need for external polarity alignment in designs like RS-485 or CAN FD physical layers.
Can MXDA3KP9.0CA be used for IEC61000-4-5 Class 4 lightning testing?
Yes, MXDA3KP9.0CA is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with 2 Ω source impedance, as confirmed in the Applications/Benefits section of RF01243 Rev B. Its 3000 W PPP rating and 194.8 A IPP capability meet the 4 kV open-circuit voltage requirement under that condition. The MXDA3KP9.0CA must be mounted per recommended pad layout and thermal relief to sustain repeated Class 4 pulses.
What is the meaning of the "C" in MXDA3KP9.0CA?
The "C" in MXDA3KP9.0CA denotes bidirectional polarity per Microsemi's part numbering convention shown on page 2 of RF01243 Rev B. It distinguishes the device from unidirectional variants like MXDA3KP9.0A. This "C" suffix directly maps to internal monolithic dual-diode architecture enabling symmetrical clamping - a key functional differentiator confirmed in the Electrical Characteristics table and polarity description under Mechanical and Packaging.
