Product details
Overview
MXDA3KP17AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 17 V standoff voltage (VWM), 18.9–20.9 V breakdown voltage (V(BR)), and 27.6 V clamping voltage (VC) at 106.6 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 MXDA3KP17AE3 datasheet, MXDA3KP17AE3 pinout, MXDA3KP17AE3 application, or MXDA3KP17AE3 equivalent, key selection criteria include its 17 V working voltage, 27.6 V clamping performance at 106.6 A, RoHS-compliant e3 marking, -55°C to +150°C operating range, and MIL-PRF-19500 upscreening capability for high-reliability deployments.
Technical Context
This TVS array uses silicon avalanche diode technology optimized for fast response (<100 ps rise time) and high-energy absorption in compact surface-mount packages. Its unidirectional polarity enables DC-biased line protection with cathode-anode orientation defined by pin 1 dot marking.
The device operates within a junction temperature range of -55°C to +150°C and maintains specified clamping performance under 10/1000 µs surge waveforms at ≤0.05% duty cycle. Standby leakage current is limited to ≤2 µA at 17 V, ensuring minimal impact on protected circuit bias conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17 V maximum continuous reverse standoff voltage - sets upper limit for protected line's normal operating peak voltage |
| V(BR) min/max | 18.9–20.9 V breakdown range at 1 mA - ensures reliable turn-on before downstream component damage thresholds |
| VC @ IPP | 27.6 V clamping voltage at 106.6 A peak pulse - defines worst-case overvoltage seen by protected IC during surge |
| PPP | 3000 W peak pulse power rating @ 10/1000 µs - quantifies single-event energy handling capacity |
| ID @ VWM | ≤2 µA standby leakage current - avoids signal distortion or power loss in high-impedance sensing/control paths |
| TJ/TSTG | -55°C to +150°C operating and storage range - supports deployment in harsh industrial, aerospace, and automotive under-hood environments |
Pinout & Package
MXDA3KP17AE3 is housed in a void-free thermosetting epoxy package meeting UL94V-0, with tin-lead or matte-tin plating per MIL-STD-750 Method 2026. Pin 1 is marked by a dot on top; odd-numbered pins are cathodes per device polarity convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Protected line connects to anode (Pin 2); cathode ties to system ground or higher-potential rail for unidirectional clamping |
| Pin 2 | Anode of Channel 1 | Input terminal for DC-biased signal/power line requiring transient suppression toward ground |
| Pin 3 | Cathode of Channel 2 | Second independent TVS channel - enables dual-line protection (e.g., differential pair or redundant supply) |
| Pin 4 | Anode of Channel 2 | Second input terminal; electrically isolated from Channel 1, allowing separate clamping paths |
Key Features
| Feature | Design Value |

Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
Use Scenario: Protection of gate drivers and feedback sensors in variable-frequency drives exposed to inductive kickback and grid transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed across DC bus or control lines to divert >100 A surges away from sensitive MOSFET drivers. Use Value: Limits voltage overshoot to ≤27.6 V during 10/1000 µs events, preventing latch-up or oxide rupture in 20–30 V rated gate drivers. | Use Scenario: Input-stage surge suppression in AC/DC front-ends of telecom rectifiers subjected to utility switching surges and lightning-induced ring waves. IC Role / Device Role / Timing Role: Primary overvoltage clamp on bulk capacitor input rails, coordinated with MOVs for multi-level protection architecture. Use Value: Absorbs 3000 W peak pulses without degradation, maintaining <2 µA leakage to avoid no-load power waste in energy-efficient systems. |
| Railway Signaling Interfaces | Medical Imaging Power Modules |
Use Scenario: Protection of RS-485 communication lines and sensor inputs in track-side signaling units operating in high-EMI railway corridors. IC Role / Device Role / Timing Role: Bidirectional-capable layout (though MXDA3KP17AE3 is unidirectional) used in conjunction with series impedance to suppress both positive and negative transients on data lines. Use Value: Fast <100 ps response ensures clamping initiates before ESD pulses (IEC61000-4-2) propagate into PHY ICs, preserving data integrity. | Use Scenario: DC link protection in high-voltage X-ray generator inverters where transient-induced gate failure could cause catastrophic tube arcing. IC Role / Device Role / Timing Role: Secondary surge limiter placed after primary MOV stage to handle residual fast-rising edges that bypass slower components. Use Value: 17 V VWM aligns with 15 V auxiliary rails, while 27.6 V VC ensures IGBT gate-emitter voltage stays within ±30 V safe operating area during surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17A | 600 W PPP rating, same 17 V VWM and unidirectional polarity, DO-214AA package | Limited to lower-energy surges (e.g., ESD/EFT only); not rated for IEC61000-4-5 Class 4 | Select when board space is constrained and surge threat level is ≤1 kW - MXDA3KP17AE3 required for full 3 kW lightning immunity. |
| SMCJ17A | 1500 W PPP, same VWM and unidirectional configuration, larger DO-214AB package | Insufficient for 42 Ω IEC61000-4-5 Class 4 testing; suitable for Class 1–2 only | Use where cost is prioritized over ultimate surge margin; MXDA3KP17AE3 delivers 2× the power rating in same footprint. |
Compared with SMBJ17A and SMCJ17A, MXDA3KP17AE3 provides double the peak pulse power (3000 W vs. 1500/600 W) in a surface-mount package qualified for MIL-PRF-19500 upscreening - making it the only option among the three certified for high-reliability Class 4 lightning protection in mission-critical infrastructure.

FAQ
What is the clamping voltage of MXDA3KP17AE3 at its rated peak pulse current?
The MXDA3KP17AE3 has a maximum clamping voltage (VC) of 27.6 V at its rated peak pulse current (IPP) of 106.6 A under 10/1000 µs waveform conditions. This value is measured per standard test methods defined in the datasheet and represents the worst-case overvoltage imposed on protected circuitry during a full-rated surge event. The MXDA3KP17AE3 maintains this clamping performance across its specified operating temperature range.
Is MXDA3KP17AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXDA3KP17AE3 is RoHS compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide. The 'e3' designation specifies matte-tin plating and full compliance with EU Directive 2011/65/EU, including restrictions on lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE. This makes MXDA3KP17AE3 suitable for environmentally regulated commercial and industrial designs without exemption requests.
Can MXDA3KP17AE3 be used for bidirectional transient protection?
No, MXDA3KP17AE3 is a unidirectional TVS device, as indicated by the absence of 'C' in its part number (e.g., MDA3KP17CA would be bidirectional). Its electrical behavior clamps only positive-going transients relative to the cathode connection. For bidirectional protection, a separate complementary device or a dedicated bidirectional variant must be selected - MXDA3KP17AE3 is intended for DC-biased lines where polarity is fixed.
What is the maximum standoff voltage (VWM) and why is it critical for MXDA3KP17AE3 selection?
The maximum standoff voltage (VWM) of MXDA3KP17AE3 is 17 V, meaning it can safely remain non-conductive across protected lines operating up to 17 V peak. Selecting a VWM ≥ the circuit's maximum normal operating voltage prevents false triggering while ensuring breakdown occurs just above that threshold. For MXDA3KP17AE3, this allows use on 15 V auxiliary rails or 12 V systems with margin, avoiding unnecessary leakage or premature conduction.
Does MXDA3KP17AE3 require special handling or baking prior to reflow soldering?
No, MXDA3KP17AE3 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it is not humidity-sensitive and requires no dry pack, baking, or floor-life controls before SMT assembly. It withstands standard reflow profiles up to 260°C for 10 seconds, and its void-free epoxy body ensures mechanical stability during thermal cycling - simplifying manufacturing for MXDA3KP17AE3 integration.
