Product details
Overview
MXDA3KP9.0A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in industrial power interfaces. 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 (VC) at 194.8 A peak pulse current, and operates from −55 °C to +150 °C.
For engineers reviewing the MXDA3KP9.0A datasheet, MXDA3KP9.0A pinout, MXDA3KP9.0A application, or MXDA3KP9.0A equivalent, key selection criteria include IEC61000-4-5 Class 4 compliance with 2 Ω source impedance, 10 µA standby current at VWM, RoHS-compliant matte-tin plating, and UL94V-0 void-free epoxy packaging.
Technical Context
The MXDA3KP9.0A is a single-channel unidirectional TVS diode optimized for fast clamping of high-energy transients in DC power rails and signal lines. Its <100 ps response time enables effective suppression of ESD per IEC61000-4-2 and EFT per IEC61000-4-4, while its 3000 W peak pulse power rating at 10/1000 µs supports robust secondary lightning protection per IEC61000-4-5.
It is rated for 194.8 A peak impulse current (IPP) at 15.4 V clamping, with 10 µA maximum standby leakage at 9.0 V standoff, and exhibits full surge testing per lot. Polarity is defined by odd-numbered pins as cathodes, and it complies with MIL-PRF-19500 screening options for high-reliability applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum continuous DC or peak AC operating voltage before clamping initiates |
| V(BR) min/max | 10.0–11.1 V @ 1 mA - Ensures reliable turn-on above system operating voltage with margin |
| VC @ IPP | 15.4 V @ 194.8 A - Limits downstream voltage stress during worst-case 10/1000 µs surge |
| ID @ VWM | 10 µA - Low leakage preserves efficiency in battery-backed or low-power monitoring circuits |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy surges without thermal runaway or parametric shift |
| TJ/TSTG | −55 °C to +150 °C - Supports operation in harsh environments including automotive under-hood and industrial motor drives |
| Moisture Level | IPC/JEDEC J-STD-020B Level 1 - No dry pack required; simplifies handling and reflow process |
Pinout & Package
MXDA3KP9.0A uses a 2-pin surface-mount package with void-free UL94V-0 thermosetting epoxy body and matte-tin-plated terminals. Pin 1 (cathode) is marked by a dot on the top surface; polarity follows standard TVS convention where odd-numbered pins are cathodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line (e.g., DC input rail); clamps positive transients to ground when voltage exceeds V(BR) |
| Pin 2 | Anode | Typically tied to system ground; completes conduction path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W Peak Pulse Power | Enables single-device protection against IEC61000-4-5 Class 4 lightning surges (2 Ω source) without cascading devices |
| 10 µA Standby Current | Minimizes quiescent power loss in always-on industrial sensors and remote monitoring nodes |
| UL94V-0 Epoxy Body | Provides flame-retardant mechanical integrity in enclosed power supplies and motor controllers |
| MIL-PRF-19500 Screening Option | Supports aerospace and defense programs requiring wafer/lot traceability and 3σ ID screening |
| RoHS Compliant (e3) | Meets global environmental compliance requirements without lead-free solder compatibility compromises |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|
Use Scenario: Protection of 24 V DC control inputs against switching transients from contactor coil de-energization and nearby arc welding. IC Role / Device Role / Timing Role: Unidirectional TVS clamping positive surges on supply rails to prevent latch-up in PLC I/O ASICs. Use Value: 15.4 V clamping ensures microcontroller reset circuitry remains below 18 V absolute max rating during 194.8 A transients. | Use Scenario: Surge protection on −48 V telecom rectifier outputs exposed to induced RF and lightning-induced ground potential rise. IC Role / Device Role / Timing Role: Cathode-to-rail placement absorbs positive-going transients relative to negative return, preserving -48 V rail integrity. Use Value: 9.0 V VWM allows direct placement on −48 V systems using appropriate biasing, with 10 µA leakage avoiding load regulation drift. |
| Renewable Energy Inverters | Railway Signaling Interfaces |
Use Scenario: DC-link protection in solar string inverters subject to rapid voltage reversals and grid-switching transients. IC Role / Device Role / Timing Role: Fast-clamping TVS placed across DC bus capacitors to limit overvoltage during fault clearing. Use Value: <100 ps response time prevents capacitor overvoltage before protection ICs can react, reducing need for oversized bulk capacitance. | Use Scenario: Input protection for 24 V signaling modules in trackside cabinets exposed to traction return currents and lightning coupling. IC Role / Device Role / Timing Role: Primary-level TVS on sensor input lines meeting EN 50121-4 immunity requirements. Use Value: IEC61000-4-5 Class 4 compliance with 2 Ω source confirms suitability for high-energy railway surge environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A | 600 W PPP rating, 12.6 V VC @ 48.7 A IPP, DO-214AC package | Limited to lower-energy transients; not rated for IEC61000-4-5 Class 4 (2 Ω) | Select when cost-sensitive designs tolerate reduced surge margin and smaller PCB footprint |
| SMCJ9.0A | 1500 W PPP rating, 14.4 V VC @ 104.2 A IPP, DO-214AB package | Half the peak power handling; requires parallel staging for Class 4 compliance | Choose when legacy layout constraints mandate DO-214AB and surge energy is verified ≤1500 W |
Compared with SMAJ9.0A and SMCJ9.0A, the MXDA3KP9.0A delivers 2× and 2× higher peak pulse power respectively, enabling single-device Class 4 lightning protection without layout redesign or derating penalties.

FAQ
What is the clamping voltage of the MXDA3KP9.0A at its rated peak pulse current?
The MXDA3KP9.0A 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 guaranteed per datasheet Figure 2 and ensures downstream components remain within safe operating voltage limits during surge events. The MXDA3KP9.0A achieves this clamping performance while maintaining low leakage and high thermal stability across its full temperature range.
Is the MXDA3KP9.0A suitable for IEC61000-4-5 Class 4 lightning protection?
Yes, the MXDA3KP9.0A is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 2 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse power and 194.8 A IPP capability meet the 4 kV/2 Ω test requirement. The MXDA3KP9.0A is one of only three parts in the MDA3KP family qualified for this highest severity level under 2 Ω conditions.
What does the 'A' suffix indicate in MXDA3KP9.0A?
The 'A' suffix in MXDA3KP9.0A denotes unidirectional polarity, meaning the device conducts only during positive voltage transients relative to its anode. This distinguishes it from bidirectional variants (e.g., MXDA3KP9.0CA) that clamp both polarities. The MXDA3KP9.0A is intended for DC power rail protection where polarity is fixed and only one-directional surges require suppression.
Does the MXDA3KP9.0A require moisture sensitivity level (MSL) baking before reflow?
No, the MXDA3KP9.0A is rated IPC/JEDEC J-STD-020B Level 1, meaning it has unlimited floor life and no dry pack or pre-reflow baking is required. This simplifies manufacturing logistics and eliminates moisture-related popcorning risk during standard lead-free reflow profiles. The MXDA3KP9.0A's void-free UL94V-0 epoxy body contributes to its robust moisture resistance.
What is the maximum operating junction temperature for the MXDA3KP9.0A?
The MXDA3KP9.0A has a specified junction and storage temperature range of −55 °C to +150 °C. This allows reliable operation in demanding environments such as industrial motor drive cabinets, railway electronics enclosures, and outdoor renewable energy installations. The MXDA3KP9.0A maintains its 9.0 V VWM and 15.4 V VC specifications across this full range, with derating applied to peak pulse power above 25 °C per Figure 3.
