Product details
Overview
MXDA3KP15CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, designed for secondary lightning protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD suppression per IEC61000-4-2, and EFT protection per IEC61000-4-4. It features a 15 V standoff voltage (VWM), 16.7–18.5 V breakdown range (V(BR)), 24.4 V max clamping voltage at 123 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MXDA3KP15CAE3 datasheet, MXDA3KP15CAE3 pinout, MXDA3KP15CAE3 application, or MXDA3KP15CAE3 equivalent, this device serves as a high-reliability, RoHS-compliant TVS for industrial power supplies, telecom interfaces, and automotive control modules requiring robust surge immunity with minimal PCB footprint and no dry-pack handling.
Technical Context
The MXDA3KP15CAE3 is a bidirectional TVS diode array optimized for fast transient suppression across both polarities, with sub-5 ns response time and <100 ps turn-on delay. Its silicon avalanche structure delivers precise clamping at 24.4 V under 123 A (10/1000 µs waveform), enabling reliable protection of downstream ICs without overvoltage stress.
It complies with MIL-PRF-19500 screening options for high-reliability applications and supports full lot traceability, 3σ standby current screening, and surge testing per JEDEC JESD22-A114. Moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no baking required prior to reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 15 V - maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) Min/Max | 16.7–18.5 V @ 1 mA - ensures predictable avalanche initiation across production lots |
| VC @ IPP | 24.4 V @ 123 A (10/1000 µs) - limits voltage seen by protected circuit during worst-case surge |
| PPP | 3000 W - peak power dissipation capability defines surge energy handling capacity |
| ID @ VWM | 2 µA max - ultra-low leakage preserves signal integrity and minimizes standby power loss |
| TJ Range | –55 °C to +150 °C - enables deployment in under-hood automotive or industrial ambient environments |
| RoHS | e3 suffix - lead-free matte-tin plating compliant with EU Directive 2011/65/EU |
Pinout & Package
MXDA3KP15CAE3 is housed in a DO-214AB (SMC) plastic package with two terminals: Pin 1 (cathode) and Pin 2 (anode). Polarity is marked by a dot on the top surface adjacent to Pin 1. The void-free UL94V-0 epoxy body supports reflow soldering up to 260 °C for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Bidirectional) | Common terminal for both avalanche paths; connects to system ground or reference plane in clamp-to-rail configurations |
| Pin 2 | Anode (Bidirectional) | Common terminal opposite Pin 1; forms symmetrical clamping path for ± transients in differential or single-ended lines |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables symmetric protection of AC-coupled or floating signal lines without polarity constraints |
| 3000 W peak pulse rating | Supports IEC61000-4-5 Class 4 surges (42 Ω source) in compact SMC footprint |
| Sub-5 ns response time | Clamps ESD events before sensitive logic or analog inputs are damaged |
| MIL-PRF-19500 screening option | Allows qualification for aerospace, defense, and critical infrastructure deployments |
| Level 1 moisture sensitivity | Eliminates pre-reflow baking, reducing manufacturing cost and process complexity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | 600 W PPP rating, same VWM and bidirectional configuration, DO-214AA package | Limited to IEC61000-4-5 Class 2 (42 Ω) and ESD/EFT only - insufficient for Class 4 lightning | Select when space-constrained designs require lower surge capacity and reduced thermal mass |
| SMCJ15CA | 1500 W PPP rating, identical DO-214AB package, same VWM and clamping voltage tolerance | Meets IEC61000-4-5 Class 3 (42 Ω) but not Class 4; lower energy margin than MXDA3KP15CAE3 | Choose where cost optimization is prioritized and full 3 kW surge headroom is not required |
Compared with SMBJ15CA and SMCJ15CA, MXDA3KP15CAE3 provides double the peak pulse power of SMCJ15CA and five times that of SMBJ15CA, enabling direct use in Class 4 secondary lightning environments without derating or parallel devices - critical for rail, energy, and defense applications demanding highest surge resilience.

FAQ
What is the clamping voltage of MXDA3KP15CAE3 at its rated peak pulse current?
The MXDA3KP15CAE3 has a maximum clamping voltage (VC) of 24.4 V at 123 A peak pulse current under the standard 10/1000 µs waveform. This value is guaranteed across temperature and production lots, ensuring consistent overvoltage protection for downstream circuitry without exceeding safe operating limits of 3.3 V or 5 V logic interfaces.
Is MXDA3KP15CAE3 suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MXDA3KP15CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as confirmed in the manufacturer's application table on page 1. Its 3000 W peak pulse power and 24.4 V clamping voltage enable compliance without external derating or parallel staging.
What does the 'C' and 'e3' suffix mean in MXDA3KP15CAE3?
In MXDA3KP15CAE3, the 'C' denotes bidirectional polarity, meaning the device clamps transients of either polarity between its two terminals. The 'e3' suffix indicates RoHS-compliant matte-tin plating per EU Directive 2011/65/EU, with no lead content and full compatibility with standard Pb-free reflow profiles.
Does MXDA3KP15CAE3 require moisture preconditioning before reflow soldering?
No, MXDA3KP15CAE3 is rated IPC/JEDEC J-STD-020B Level 1 for moisture sensitivity, meaning it may be stored indefinitely at ambient conditions and placed directly into reflow without baking. This eliminates process steps, reduces risk of popcorn cracking, and lowers manufacturing overhead.
How does MXDA3KP15CAE3 differ from unidirectional variants like MXDA3KP15AE3?
MXDA3KP15CAE3 is bidirectional and protects both positive and negative transients symmetrically, making it ideal for AC lines, differential buses, or floating references. In contrast, MXDA3KP15AE3 is unidirectional and only clamps positive-going surges relative to ground - requiring separate grounding topology and unsuitable for bidirectional signal paths.
