Product details
Overview
MXDA3KP7.5CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for secondary lightning protection per IEC61000-4-5 with 12 Ω and 2 Ω source impedances, ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient clamping. It features 7.5 V standoff voltage (VWM), 8.33–9.21 V breakdown range (V(BR)), 12.9 V max clamping voltage (VC) at 232.6 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MXDA3KP7.5CAE3 datasheet, MXDA3KP7.5CAE3 pinout, MXDA3KP7.5CAE3 application, or MXDA3KP7.5CAE3 equivalent, key selection criteria include bidirectional polarity, 3000 W 10/1000 µs surge rating, RoHS-compliant matte-tin plating, UL94V-0 epoxy case, and compatibility with Class 1–3 secondary lightning protection under 12 Ω impedance per IEC61000-4-5.
Technical Context
The MXDA3KP7.5CAE3 implements a silicon avalanche diode structure optimized for fast response (<5 ns) and high-energy transient absorption. Its bidirectional configuration enables symmetrical clamping across both polarities without external circuitry, supporting AC-coupled signal lines and differential bus protection.
It delivers 3000 W peak pulse power at 10/1000 µs waveform with full surge testing per production lot, and maintains stable clamping performance over its –55 °C to +150 °C junction temperature range, supported by wafer-level traceability and MIL-PRF-19500 screening options.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.5 V - maximum continuous operating voltage before clamping begins; matches 5 V or 3.3 V rail systems with margin |
| V(BR) min–max | 8.33–9.21 V @ 1 mA - verified avalanche onset range ensuring predictable turn-on behavior |
| VC @ IPP | 12.9 V @ 232.6 A - clamping voltage during worst-case 10/1000 µs surge, limiting downstream stress |
| PPP | 3000 W @ 10/1000 µs - energy-handling capacity sufficient for IEC61000-4-5 Class 3 (12 Ω) |
| TJ / TSTG | –55 °C to +150 °C - wide thermal range enabling use in automotive under-hood and industrial control environments |
| RoHS | e3 marking - lead-free matte-tin termination compliant with JEDEC J-STD-020B Level 1 moisture sensitivity |
Pinout & Package
MXDA3KP7.5CAE3 uses a 2-pin surface-mount DO-214AB (SMC) package with void-free UL94V-0 thermosetting epoxy body and tin-lead or matte-tin plating. Pin 1 is cathode (marked by dot); polarity is bidirectional, so both terminals serve as symmetrical anode/cathode pairs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (bidirectional) | Common reference terminal; functions as cathode during positive transients and anode during negative transients |
| Pin 2 | Anode (bidirectional) | Complementary terminal; forms symmetrical clamping path with Pin 1 for AC or differential signals |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection of AC lines, RS-485, CAN, or Ethernet PHY interfaces without polarity awareness |
| 3000 W 10/1000 µs rating | Meets IEC61000-4-5 Class 3 (12 Ω source) and Class 2 (2 Ω source) requirements without derating at 25 °C |
| <5 ns response time | Clamps ESD events (IEC61000-4-2) and EFT bursts (IEC61000-4-4) before sensitive ICs are damaged |
| MIL-PRF-19500 screening option | Supports high-reliability aerospace and defense applications via optional upscreening with lot traceability |
Applications

IC Role / Device Role / Timing Role: Interface-level TVS on data lines entering patient-connected devices. Use Value: Sub-5 ns response prevents data corruption during 4 kV EFT bursts (IEC61000-4-4), maintaining diagnostic data fidelity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.5CA | 600 W PPP rating, same VWM and bidirectional polarity, SMB package (smaller footprint) | Limited to Class 1–2 IEC61000-4-5; insufficient for Class 3 12 Ω tests | Select when board space is constrained and surge energy is ≤600 W |
| 1.5KE7.5CA | 1500 W PPP, axial-leaded DO-15 package, higher leakage ID (500 µA vs. 100 µA) | Not suitable for automated SMT assembly; requires through-hole layout and wave soldering | Select only for legacy through-hole designs where rework to SMT is not feasible |
Compared with SMBJ7.5CA and 1.5KE7.5CA, MXDA3KP7.5CAE3 provides double the surge energy handling of the SMBJ series and enables SMT scalability absent in the axial 1.5KE series-making it optimal for new industrial and automotive designs requiring Class 3 immunity and automated manufacturing.

FAQ
What is the clamping voltage of MXDA3KP7.5CAE3 at its rated peak pulse current?
The MXDA3KP7.5CAE3 has a maximum clamping voltage (VC) of 12.9 V at its rated peak pulse current (IPP) of 232.6 A under 10/1000 µs waveform conditions. This value is measured per standard test methods defined in the datasheet and guarantees predictable voltage limiting during surge events, protecting downstream components such as microcontrollers and interface ICs from overvoltage stress.
Is MXDA3KP7.5CAE3 suitable for IEC61000-4-5 Class 3 testing?
Yes, MXDA3KP7.5CAE3 is explicitly rated for IEC61000-4-5 Class 3 secondary lightning protection with a 12 Ω source impedance. Its 3000 W peak pulse power rating and validated clamping performance at 232.6 A ensure compliance without derating at 25 °C, as confirmed in the manufacturer's application guidance and test data for the MDA3KP family.
Does MXDA3KP7.5CAE3 have bidirectional polarity, and how does that affect circuit placement?
Yes, MXDA3KP7.5CAE3 is a bidirectional TVS, indicated by the "C" suffix in its part number. This allows symmetrical clamping on AC-coupled or differential signal lines-such as RS-485, CAN, or LIN-without regard to orientation. Engineers may place MXDA3KP7.5CAE3 across any two nodes requiring balanced overvoltage protection, eliminating polarity-check steps during layout and assembly.
What is the maximum operating temperature range for MXDA3KP7.5CAE3?
The MXDA3KP7.5CAE3 supports a junction and storage temperature range of –55 °C to +150 °C. This wide thermal capability enables reliable operation in under-hood automotive environments, industrial enclosures with minimal airflow, and outdoor telecom cabinets-where ambient temperatures exceed typical commercial-grade component limits.
How does the e3 marking on MXDA3KP7.5CAE3 relate to its termination finish and moisture sensitivity?
The e3 marking on MXDA3KP7.5CAE3 indicates RoHS-compliant matte-tin plating per JEDEC standards, with moisture sensitivity level (MSL) 1 per IPC/JEDEC J-STD-020B-meaning no dry pack or baking is required prior to reflow. This simplifies SMT manufacturing flow and ensures long-term solderability without special handling, unlike higher-MSL discrete TVS devices.
