Product details
Overview
MXDA3KP14AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 14 V standoff voltage (VWM), 15.6–17.2 V breakdown voltage (V(BR)), and 23.2 V clamping voltage (VC) at 129.4 A peak pulse current. It provides secondary lightning protection per IEC61000-4-5 (42 Ω, Class 1–4), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in industrial power interfaces.
For engineers reviewing the MXDA3KP14AE3 datasheet, MXDA3KP14AE3 pinout, MXDA3KP14AE3 application, or MXDA3KP14AE3 equivalent, key selection criteria include its 14 V working standoff, 23.2 V clamping at 129.4 A, -55°C to +150°C operating junction temperature, RoHS-compliant e3 marking, and unidirectional polarity for DC-biased signal/power line protection.
Technical Context
This TVS array uses silicon avalanche diode technology to clamp transient overvoltages within <100 ps response time. It is rated for 3000 W peak pulse power at 10/1000 µs waveform and undergoes full lot surge testing per specification.
Designed for high-reliability vertical mounting, it features void-free UL94V-0 epoxy packaging, tin-lead or matte-tin terminations, and polarity defined by dot-marked Pin 1 (cathode). Standby leakage is limited to ≤2 µA at 14 V, supporting low-power system monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 14 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 15.6–17.2 V @ 1 mA - Ensures reliable turn-on above normal operating voltage while avoiding false triggering |
| VC @ IPP | 23.2 V @ 129.4 A - Limits downstream voltage stress during worst-case 10/1000 µs transients |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy surges typical of lightning-induced coupling or inductive load switching |
| ID @ VWM | ≤2 µA - Minimizes standby power loss and avoids interference with high-impedance sensing circuits |
| TJ/TSTG | -55°C to +150°C - Supports operation in extended industrial and automotive under-hood environments |
| RoHS | e3 marking - Confirms lead-free termination compliant with EU Directive 2011/65/EU |
Pinout & Package
MXDA3KP14AE3 is housed in a vertical-mount, transfer-molded thermosetting epoxy package (UL94V-0) with two terminals. Pin 1 (cathode) is marked by a dot on the top surface; Pin 2 is anode. Polarity follows standard unidirectional TVS convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; clamps positive transients to ground when referenced to Pin 2 |
| Pin 2 | Anode | Typically tied to system ground or low-impedance return path; completes clamping current path |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse rating | Enables robust protection against IEC61000-4-5 Level 4 surges (42 Ω source) without derating at 25°C |
| Clamping response <100 ps | Prevents voltage overshoot before sensitive ICs (e.g., RS-485 transceivers, microcontroller I/O) are damaged |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing cost and risk |
| Full lot surge testing | Guarantees every production batch meets 3000 W pulse capability-no sampling-based qualification |
| Wafer and assembly lot traceability | Supports failure analysis and field return investigations in aerospace, defense, and medical applications |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|
Use Scenario: Protection of 24 V DC control inputs against inductive kickback from contactor coils and relay switching. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input terminal and ground to clamp positive transients. Use Value: MXDA3KP14AE3's 14 V VWM matches nominal 24 V rail derated for ripple, while 23.2 V VC prevents MCU GPIO damage during 129.4 A surges. | Use Scenario: Surge protection on -48 V telecom power feed lines exposed to lightning-induced coupling on outdoor plant wiring. IC Role / Device Role / Timing Role: Cathode-to-line configuration clamps positive surges to ground; anode tied to -48 V return. Use Value: With 14 V standoff and 23.2 V clamping, MXDA3KP14AE3 limits transient voltage to safe levels for downstream DC/DC converters without affecting steady-state bias. |
| Programmable Logic Controllers | Renewable Energy Inverters |
Use Scenario: Input protection for analog sensor channels (e.g., 4–20 mA loops) connected to field wiring subject to EFT bursts. IC Role / Device Role / Timing Role: Series-connected unidirectional TVS on signal line, with cathode toward PLC input. Use Value: ≤2 µA ID ensures minimal loading on precision current loops; fast <100 ps response suppresses EFT edges per IEC61000-4-4. | Use Scenario: DC bus protection in solar string inverters where PV arrays induce high-voltage transients during rapid cloud cover changes or fault clearing. IC Role / Device Role / Timing Role: Parallel-mounted TVS across DC link capacitor to clamp overvoltage spikes before they reach IGBT gate drivers. Use Value: 3000 W PPP rating and -55°C to +150°C TJ range allow MXDA3KP14AE3 to operate reliably in outdoor enclosures with wide ambient swings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14A | 600 W PPP rating, SMA package, 25.1 V VC @ 24.7 A IPP | Lower energy handling; suitable only for ESD/EFT, not IEC61000-4-5 Class 4 | Select when board space is constrained and surge threat level is limited to IEC61000-4-2/4-4 |
| SMCJ14A | 1500 W PPP rating, SMC package, 23.2 V VC @ 64.5 A IPP | Half the peak pulse power; requires parallel devices for 3000 W compliance | Choose if existing layout uses SMC footprint and surge requirements are ≤1500 W |
Compared with SMAJ14A and SMCJ14A, MXDA3KP14AE3 delivers double the pulse power of SMCJ14A and five times that of SMAJ14A in the same functional voltage class-enabling single-device Class 4 lightning protection without layout redesign or paralleling complexity.

FAQ
What is the clamping voltage of MXDA3KP14AE3 and how is it measured?
The clamping voltage (VC) of MXDA3KP14AE3 is 23.2 V, measured at 129.4 A peak pulse current under 10/1000 µs waveform conditions. This value represents the maximum voltage seen across the device during a standardized surge event and is critical for ensuring downstream components remain below their absolute maximum ratings. MXDA3KP14AE3 maintains this clamping performance across its full operating temperature range.
Is MXDA3KP14AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXDA3KP14AE3 is RoHS compliant, as confirmed by the 'e3' suffix in its part number. Per Microsemi's nomenclature, 'e3' denotes matte-tin termination meeting EU Directive 2011/65/EU requirements. The device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits, and is suitable for lead-free reflow soldering processes.
How does MXDA3KP14AE3 differ from bidirectional variants like MXDA3KP14CE3?
MXDA3KP14AE3 is unidirectional and designed for DC-biased lines where only positive transients require suppression (e.g., 14 V supply rails). MXDA3KP14CE3 is bidirectional and protects AC or bipolar signals (e.g., data lines), clamping both polarities. Their VWM, V(BR), and VC values differ accordingly-MXDA3KP14AE3 has 14 V VWM and 15.6–17.2 V V(BR), while the 'C' version has symmetric breakdown behavior unsuitable for DC applications.
What is the maximum operating temperature for MXDA3KP14AE3 and how does it affect surge capability?
MXDA3KP14AE3 operates from -55°C to +150°C junction temperature. Its 3000 W peak pulse power rating applies at 25°C; derating begins above 25°C per Figure 3 in the datasheet-e.g., at 100°C, usable PPP drops to ~65% of rated value. Designers must apply thermal modeling to ensure sustained surge events do not exceed TJ limits, especially in enclosed industrial enclosures.
Can MXDA3KP14AE3 be used for IEC61000-4-5 Class 4 lightning protection?
Yes, MXDA3KP14AE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as stated in the Applications section of the datasheet. Its 3000 W PPP rating and 23.2 V clamping voltage meet the 4 kV test level requirement when applied with appropriate PCB layout (short traces, low-inductance grounding) and upstream current limiting.
