Product details
Overview
MXDA3KP10CA 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 10 V reverse standoff voltage (VWM), 11.1–12.3 V breakdown voltage (V(BR)), 17.0 V maximum clamping voltage (VC) at 176.4 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) in power supply inputs.
For engineers reviewing the MXDA3KP10CA datasheet, MXDA3KP10CA pinout, MXDA3KP10CA application, or MXDA3KP10CA equivalent, this device delivers verified 3000 W surge capability at 10/1000 µs, bidirectional polarity, RoHS-compliant e3 marking, and MIL-PRF-19500 upscreening options - critical for ruggedized DC bus and interface line protection.
Technical Context
The MXDA3KP10CA employs silicon avalanche diode technology with sub-5 ns response time and <100 ps junction turn-on latency, enabling suppression of fast-rising transients before downstream components are stressed. Its bidirectional construction allows symmetrical clamping on AC-coupled or floating signal lines without polarity concerns.
It is rated for 3000 W peak pulse power under 10/1000 µs waveform, with full surge testing per specification and 3σ lot norm screening on standby current (ID). Moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous DC or RMS operating voltage before clamping begins |
| V(BR) min–max | 11.1–12.3 V @ 1 mA - ensures reliable avalanche initiation across temperature and process variation |
| VC @ IPP | 17.0 V @ 176.4 A - limits voltage seen by protected ICs during worst-case 10/1000 µs surge |
| IPP | 176.4 A - peak current survivable without degradation, derived from 3000 W / VC |
| TJ range | –55 °C to +150 °C - supports operation in extended-temperature industrial and avionics environments |
| Moisture Level | IPC/JEDEC J-STD-020B Level 1 - zero bake requirement prior to reflow, reducing assembly cost |
| RoHS | e3 marking - matte tin plating, lead-free, compliant with EU Directive 2011/65/EU |
Pinout & Package
MXDA3KP10CA uses a 2-pin surface-mount DO-214AB (SMC) package with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity defined by dot marking indicating Pin 1 (cathode for unidirectional; symmetric for bidirectional). Odd-numbered pins are cathodes - but as a 2-pin bidirectional device, both terminals are functionally identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | Common terminal; symmetrical conduction path - no polarity dependency in AC or floating applications |
| Pin 2 | Anode/Cathode (bidirectional) | Paired terminal; forms differential or common-mode clamp path with Pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection of AC lines, RS-485 buses, or transformer-coupled interfaces without external polarity management |
| 3000 W peak pulse rating | Withstands IEC61000-4-5 Class 4 surges (2 Ω source) up to 176.4 A while limiting voltage to ≤17.0 V |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring wafer lot traceability, burn-in, and parametric screening per military standard |
| Sub-5 ns response time | Clamps transients before logic-level ICs or ADC inputs experience overvoltage stress - critical for data acquisition front-ends |
| Level 1 moisture sensitivity | Eliminates pre-reflow baking step, reducing manufacturing cycle time and PCB warpage risk |
Applications
| Industrial Power Input Protection | Avionics Data Bus Clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | 600 W rating, 17.0 V VC @ 35.2 A, DO-214AA package (smaller footprint) | Lower energy handling - suitable only for ESD/EFT, not lightning or inductive switching | Select when board space is constrained and surge threat level is limited to IEC61000-4-2/4-4 only. |
| 5.0SMDJ10CA | 5000 W rating, 17.0 V VC @ 294 A, larger DO-214AB package with higher thermal mass | Higher surge margin - supports Class 4 lightning with 2 Ω source impedance where MXDA3KP10CA meets Class 3 | Choose when system-level testing requires >3000 W headroom or extended thermal cycling endurance is mandated. |
Compared with SMBJ10CA and 5.0SMDJ10CA, MXDA3KP10CA provides optimal balance of 3000 W surge capacity, industry-standard SMC footprint, and MIL-PRF-19500 upscreening readiness - making it preferred for aerospace-grade power entry protection where reliability validation and controlled sourcing are mandatory.

FAQ
What is the clamping voltage of MXDA3KP10CA at its rated peak pulse current?
The MXDA3KP10CA has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPP) of 176.4 A under 10/1000 µs waveform conditions. This value is guaranteed across the full operating temperature range and ensures protected downstream circuitry remains within safe voltage limits during surge events. The MXDA3KP10CA achieves this via optimized silicon junction design and low-inductance package layout.
Is MXDA3KP10CA suitable for IEC61000-4-5 Class 4 lightning surge protection?
Yes, MXDA3KP10CA supports IEC61000-4-5 Class 4 secondary lightning protection when tested with 2 Ω source impedance, as confirmed in the official Microsemi application note RF01243. Its 3000 W rating and 176.4 A IPP enable compliance with the 2 kV/2 Ω test profile. For 12 Ω or 42 Ω source impedances, MXDA3KP10CA covers Classes 1–3 and Class 1–4 respectively - always verify system-level test configuration against the MXDA3KP10CA datasheet curves.
Does MXDA3KP10CA require moisture preconditioning before reflow soldering?
No, MXDA3KP10CA is rated IPC/JEDEC J-STD-020B Level 1 for moisture sensitivity, meaning it may be stored and processed at ambient conditions without baking. The device's void-free thermosetting epoxy body and hermetic sealing eliminate moisture ingress risk, allowing direct placement into standard lead-free reflow profiles - a key advantage over Level 3+ TVS devices that mandate pre-bake cycles.
How does the "C" suffix in MXDA3KP10CA denote device functionality?
The "C" suffix in MXDA3KP10CA explicitly indicates bidirectional construction, distinguishing it from unidirectional variants like MXDA3KP10A. This means the device provides symmetrical clamping voltage in both polarities - essential for protecting AC-coupled signals, transformer-isolated interfaces, or floating DC busses where voltage reversal can occur. The MXDA3KP10CA achieves this through back-to-back diode junctions in a single DO-214AB package.
Can MXDA3KP10CA be used in place of older MDA3KP10A in existing designs?
MXDA3KP10CA is not a direct replacement for MDA3KP10A due to polarity difference: MDA3KP10A is unidirectional, while MXDA3KP10CA is bidirectional. Substituting MXDA3KP10CA may cause unintended conduction in DC-biased circuits. If bidirectional protection is required, verify bias network compatibility; if unidirectional clamping is needed, retain MDA3KP10A or select another unidirectional variant. Always validate with actual surge testing using the MXDA3KP10CA.
