Product details
Overview
MXDA3KP17CAE3 from Microsemi is a bidirectional 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, 12 Ω, and 2 Ω source impedances), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in power supply input stages.
For engineers reviewing the MXDA3KP17CAE3 datasheet, MXDA3KP17CAE3 pinout, MXDA3KP17CAE3 application, or MXDA3KP17CAE3 equivalent, key selection criteria include bidirectional polarity, 106.6 A IPP rating at 10/1000 µs, -55 °C to +150 °C operating junction temperature, RoHS-compliant e3 termination, and UL94V-0 molded package for high-reliability industrial and telecom surge protection designs.
Technical Context
This TVS array uses silicon avalanche diode technology to clamp transient overvoltages within nanoseconds-<5 ns response time for bidirectional operation-enabling protection of downstream DC-DC converters, Ethernet PHY interfaces, and AC/DC front-end rectifiers. Its 3000 W peak pulse power rating is validated at 10/1000 µs waveform with ≤0.05% duty cycle.
The device features a thermally robust transfer-molded epoxy package rated for 260 °C soldering, moisture sensitivity level 1 (no dry pack required), and full lot traceability per MIL-PRF-19500 screening options. Standby leakage ID is ≤2 µA at 17 V VWM, ensuring minimal system power loss during normal operation.

Pinout & Package
MXDA3KP17CAE3 is housed in a DO-214AB (SMC) plastic package with two terminals: Cathode (Pin 1) and Anode (Pin 2). Polarity is marked by a dot on the top surface adjacent to Pin 1. The void-free UL94V-0 epoxy body supports reflow and wave soldering up to 260 °C for 10 seconds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Cathode) | High-side transient sink node | Connected to protected line (e.g., DC input); conducts surge current toward ground reference during positive or negative transients. |
| Pin 2 (Anode) | Reference/ground return path | Typically tied to system ground plane; completes low-inductance current loop for effective clamping under bidirectional surges. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Protects AC-coupled or floating lines (e.g., RS-485, CAN bus, PoE pairs) against ± transients without polarity constraints. |
| 3000 W peak pulse power | Handles high-energy surges such as IEC61000-4-5 Level 4 (4 kV, 42 Ω source) without degradation across >1000 cycles. |
| Sub-5 ns response time | Clamps before sensitive ICs (e.g., MCU GPIOs, PHY receivers) experience overstress-critical for ESD immunity per IEC61000-4-2. |
| MIL-PRF-19500 screening option | Enables high-reliability qualification for aerospace, defense, and critical infrastructure applications via wafer lot traceability and 3σ ID screening. |
| Moisture Level 1 | Eliminates bake-out requirement prior to SMT assembly-reduces manufacturing cost and avoids thermal damage to adjacent components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package (smaller footprint, lower thermal mass) | Limited to IEC61000-4-5 Level 2 (2 kV) and lower-energy EFT events; unsuitable for 4 kV lightning testing | Select when space-constrained layouts prioritize size over 3000 W surge capacity. |
| 1.5KE17CA | 3000 W PPP but axial-leaded DO-15 package; higher thermal resistance and manual assembly requirement | Not suitable for automated SMT production; requires through-hole PCB real estate and wave solder process | Choose only for legacy repair, prototyping, or non-SMT environments where reflow compatibility is not required. |
Compared with SMBJ17CA and 1.5KE17CA, MXDA3KP17CAE3 delivers identical 17 V standoff and bidirectional behavior but uniquely combines 3000 W surge capability with surface-mount DO-214AB packaging, enabling automated high-volume production of IEC61000-4-5 Level 4 compliant systems without thermal derating penalties.

FAQ
What is the clamping voltage of MXDA3KP17CAE3 at its rated peak pulse current?
The MXDA3KP17CAE3 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 across the device terminals during surge conduction and defines the upper voltage limit imposed on protected circuitry during transient events. It is guaranteed per the manufacturer's electrical characteristics table and verified via standardized surge testing.
Is MXDA3KP17CAE3 suitable for IEC61000-4-5 Level 4 compliance testing?
Yes, MXDA3KP17CAE3 supports IEC61000-4-5 Level 4 testing with 42 Ω source impedance, delivering full 3000 W surge absorption at 10/1000 µs. Its 106.6 A IPP rating exceeds the 100 A minimum required for 4 kV tests under this configuration. The device's sub-5 ns response time and thermal design ensure consistent performance across repeated surges without parametric shift.
Does MXDA3KP17CAE3 require baking before reflow soldering?
No, MXDA3KP17CAE3 does not require baking prior to reflow soldering. It is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ≤30 °C/60% RH without preconditioning. This eliminates bake steps in SMT line preparation, reducing process complexity and avoiding thermal stress on nearby temperature-sensitive components.
How is polarity identified on the MXDA3KP17CAE3 package?
Polarity on the MXDA3KP17CAE3 is indicated by a molded dot on the top surface of the DO-214AB package, adjacent to Pin 1 (Cathode). Per the datasheet, odd-numbered pins are cathodes-so Pin 1 is the cathode terminal and Pin 2 is the anode. This marking aligns with industry-standard SMC package conventions and is visible under standard AOI inspection.
What is the maximum operating junction temperature for MXDA3KP17CAE3?
The MXDA3KP17CAE3 has a specified junction and storage temperature range of -55 °C to +150 °C. This allows reliable operation in under-hood automotive environments, outdoor telecom enclosures, and industrial motor drive cabinets where ambient temperatures exceed 105 °C. Derating curves in the datasheet confirm 100% power rating up to 125 °C junction temperature.
