Product details
Overview
MXDA3KP36CA 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 36 V reverse standoff voltage (VWM), 40.0–44.2 V breakdown voltage (V(BR)), 58.1 V maximum clamping voltage (VC) at 51.6 A peak pulse current, and operates across –55 °C to +150 °C junction temperature. It delivers secondary lightning protection per IEC61000-4-5 with 42 Ω, 12 Ω, and 2 Ω source impedances.
For engineers reviewing the MXDA3KP36CA datasheet, MXDA3KP36CA pinout, MXDA3KP36CA application, or MXDA3KP36CA equivalent, this device is selected for robust ESD/EFT/inductive switching protection where bidirectional clamping, 3000 W surge capability, and MIL-PRF-19500 upscreening options are required.
Technical Context
The MXDA3KP36CA is a surface-mount, void-free epoxy-packaged TVS array with bidirectional polarity indicated by the "C" suffix. Its clamping response time is under 5 ns, enabling effective suppression of fast transients including ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5).
It is rated for 3000 W peak pulse power at 10/1000 μs waveform, with 2 μA maximum standby current at 36 V and full derating above 25 °C per Figure 3. Polarity follows standard convention: odd-numbered pins are cathodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous operating voltage before clamping begins; matches 33–36 V DC bus or signal lines. |
| V(BR) min–max | 40.0–44.2 V - Breakdown occurs within this range at 1 mA; ensures reliable turn-on margin above VWM. |
| VC @ IPP | 58.1 V - Clamping voltage at 51.6 A peak pulse; limits downstream voltage stress during surge events. |
| IPP | 51.6 A - Peak impulse current supported at 10/1000 μs; defines surge energy handling capacity. |
| ID @ VWM | 2 μA - Standby leakage at rated standoff; negligible power loss in always-on protection circuits. |
| TJ/TSTG | –55 to +150 °C - Wide operating and storage range suitable for under-hood, avionics, and industrial enclosures. |
| PPP | 3000 W - Peak pulse power rating at 10/1000 μs; enables protection against severe lightning-induced transients. |
Pinout & Package
MXDA3KP36CA uses a 3-pin SMD package with void-free thermosetting epoxy body (UL94V-0), tin-lead or matte-tin plating, and polarity defined by dot marking for Pin 1. Odd-numbered pins are cathodes per device configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connected to protected line; clamps positive transients to ground when referenced to Pin 2. |
| Pin 2 | Anode/Common | Shared anode node; serves as reference/ground return path for bidirectional clamping action. |
| Pin 3 | Cathode of Channel 2 | Second protected line terminal; enables dual-line or differential-mode protection topology. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetric clamping on both polarities without external diode pairing; simplifies PCB layout for AC or differential signals. |
| 3000 W peak pulse power | Supports IEC61000-4-5 Class 4 surge immunity with 42 Ω source impedance; exceeds typical industrial requirements. |
| MIL-PRF-19500 upscreening option | Enables high-reliability qualification for aerospace and defense applications via wafer/lot traceability and 3σ screening. |
| Moisture sensitivity Level 1 | No dry pack or baking required prior to reflow; reduces manufacturing overhead and avoids moisture-related popcorning. |
| Clamping response <5 ns | Fast enough to suppress ESD events (IEC61000-4-2) and EFT bursts (IEC61000-4-4) before sensitive ICs are damaged. |
Applications
| Industrial Motor Drives | Aerospace Avionics Buses |
|---|---|
Use Scenario: Protection of encoder feedback lines and RS-485 control interfaces against inductive kickback and ground bounce. IC Role / Device Role / Timing Role: Bidirectional TVS array clamping differential transients between A/B lines while referencing common ground. Use Value: Prevents latch-up or damage to isolated transceivers during 3000 W surge events with sub-5 ns response. | Use Scenario: Shielding ARINC 429 or MIL-STD-1553 data buses from lightning-induced coupling in aircraft wiring harnesses. IC Role / Device Role / Timing Role: Dual-channel bidirectional suppressor placed across bus pairs to clamp common-mode and differential surges.

| Telecom Power Feeds | Renewable Energy Inverters |
Use Scenario: Safeguarding -48 V DC telecom power inputs against load dump and lightning-induced surges on outdoor cabinets. IC Role / Device Role / Timing Role: Standoff-rated TVS connected between power rail and chassis ground to shunt surge energy away from DC/DC converters. Use Value: 36 V VWM aligns precisely with nominal -48 V system derated peaks; 58.1 V VC prevents overvoltage at downstream regulators. | Use Scenario: Protecting gate driver supply rails in solar inverters exposed to grid-switching transients and nearby lightning strikes. IC Role / Device Role / Timing Role: Low-leakage (2 μA) bidirectional suppressor placed at isolated 15 V gate bias inputs to prevent MOSFET destruction. Use Value: High TJ rating (+150 °C) ensures stable operation inside sealed inverter enclosures with elevated ambient temperatures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package. | Limited to Class 2 IEC61000-4-5; insufficient for 3000 W lightning surges. | Select when space-constrained layouts require smaller footprint and lower surge levels suffice. |
| SMCJ36CA | 1500 W PPP, same VWM and polarity, larger DO-214AB package, higher VC (68.7 V). | Meets Class 3 but not Class 4 lightning; higher clamping increases risk to downstream 3.3 V logic. | Choose for cost-sensitive industrial designs where 1500 W margin is acceptable and thermal mass allows larger package. |
Compared with SMBJ36CA and SMCJ36CA, MXDA3KP36CA delivers double the surge power handling of SMCJ36CA and five times that of SMBJ36CA while maintaining lower clamping voltage-critical for protecting modern low-voltage controllers in high-energy environments.

FAQ
What does the "C" suffix in MXDA3KP36CA indicate?
The "C" suffix denotes bidirectional polarity, meaning the MXDA3KP36CA provides symmetrical clamping for both positive and negative transients across its terminals. This eliminates the need for back-to-back unidirectional devices in AC-coupled or differential signal paths, and is confirmed in the "Part Nomenclature" section of RF01243 Rev B.
Is MXDA3KP36CA RoHS compliant?
Yes, MXDA3KP36CA is RoHS compliant, as indicated by the "e3" suffix in the full part marking per page 2 of RF01243 Rev B. The device uses annealed matte-tin plating and meets UL94V-0 flammability standards in its void-free epoxy package.
What is the maximum clamping voltage of MXDA3KP36CA and at what current is it specified?
The maximum clamping voltage (VC) of MXDA3KP36CA is 58.1 V, measured at the peak pulse current (IPP) of 51.6 A under 10/1000 μs waveform conditions. This value is listed in the Electrical Characteristics table on page 3 of RF01243 Rev B and defines the upper voltage limit imposed on protected circuitry during surge events.
Can MXDA3KP36CA be used for IEC61000-4-5 Class 4 lightning surge testing?
Yes, MXDA3KP36CA supports IEC61000-4-5 Class 4 testing with 42 Ω source impedance, as explicitly stated in the "APPLICATIONS / BENEFITS" section on page 1 of RF01243 Rev B. Its 3000 W PPP rating and 51.6 A IPP ensure compliance without derating at 25 °C.
What is the standoff voltage (VWM) and why is it critical for selecting MXDA3KP36CA?
The standoff voltage (VWM) of MXDA3KP36CA is 36 V-the maximum continuous DC or peak AC voltage the device tolerates without clamping. Per note on page 3, VWM must equal or exceed the circuit's peak operating voltage to avoid false triggering; selecting MXDA3KP36CA for a 33–36 V rail ensures reliable protection without leakage-induced power loss.
