Product details
Overview
MXDA3KP12CAE3 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 12 V reverse standoff voltage (VWM), 13.3–14.7 V breakdown voltage (V(BR)), and clamps to ≤19.9 V at 150.6 A peak pulse current (IPP).
For engineers reviewing the MXDA3KP12CAE3 datasheet, MXDA3KP12CAE3 pinout, MXDA3KP12CAE3 application, or MXDA3KP12CAE3 equivalent, key selection criteria include bidirectional polarity, 3000 W 10/1000 µs surge rating, RoHS-compliant matte-tin plating, -55°C to +150°C junction temperature range, and compatibility with industrial power supply input stages, telecom line interfaces, and automotive body control modules.
Technical Context
The MXDA3KP12CAE3 operates as a voltage-clamping TVS diode array with symmetrical bidirectional conduction, enabling protection of AC-coupled or differential signal lines without polarity constraints. Its sub-5 ns response time ensures effective suppression of ESD events and fast transients, while its 10/1000 µs waveform-rated 3000 W peak pulse power supports robust immunity against induced surges and switching transients.
Designed for high-reliability applications, it undergoes full lot surge testing and 3σ screening on standby current (ID), with wafer and assembly lot traceability per MIL-PRF-19500 optional upscreening. Moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12 V - maximum continuous DC or peak AC voltage the device blocks without clamping |
| V(BR) min/max | 13.3–14.7 V @ 1 mA - guaranteed breakdown threshold defining turn-on behavior |
| VC @ IPP | ≤19.9 V @ 150.6 A - clamping voltage during worst-case 10/1000 µs surge, limiting downstream stress |
| PPP | 3000 W @ 10/1000 µs - peak transient energy handling capacity under standardized surge waveform |
| TJ range | -55°C to +150°C - operational junction temperature window supporting harsh-environment deployment |
| Moisture Level | IPC/JEDEC J-STD-020B Level 1 - zero bake requirement before reflow, simplifying SMT process flow |
| RoHS | e3 marking - lead-free matte-tin terminal plating compliant with EU RoHS Directive 2011/65/EU |
Pinout & Package
MXDA3KP12CAE3 is housed in a DO-214AB (SMC) plastic package with void-free thermosetting epoxy body (UL94V-0 rated), tin-lead or annealed matte-tin terminals, and polarity defined by a dot marking indicating Pin 1 (cathode for unidirectional variants; symmetric for bidirectional). Odd-numbered pins are cathodes - but for bidirectional construction, both terminals behave identically.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Transient return path (bidirectional) | Common reference node for clamping action; connects to protected line or ground plane |
| Cathode (Pin 2) | Transient return path (bidirectional) | Electrically identical to Pin 1; enables symmetrical clamping across AC or differential signals |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled interfaces (e.g., RS-485, CAN FD, Ethernet PHY) without polarity-sensitive layout |
| 3000 W 10/1000 µs rating | Meets IEC61000-4-5 Class 1–4 requirements for secondary lightning with 42 Ω, 12 Ω, and 2 Ω source impedances |
| Sub-5 ns response time | Clamps ESD events (IEC61000-4-2 ±8 kV contact) before sensitive ICs experience overstress |
| MIL-PRF-19500 upscreening option | Supports aerospace and defense programs requiring extended reliability validation and lot traceability |
| Level 1 moisture sensitivity | Eliminates pre-bake step in SMT reflow, reducing manufacturing cost and cycle time |
Applications
| Industrial Power Input Protection | Telecom Line Interface |
|---|---|
Use Scenario: 24 V DC power rail feeding PLC I/O modules exposed to inductive load switching and nearby lightning-induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converters and LDOs to limit transient excursions below 20 V. Use Value: Prevents latch-up or gate oxide damage in downstream regulators by clamping 150 A surges to ≤19.9 V within 5 ns. | Use Scenario: T1/E1 line interface card in central office equipment subject to longitudinal surges and ESD during hot-plug maintenance. IC Role / Device Role / Timing Role: Bidirectional TVS array bridging tip/ring pair to protect line driver/receiver ICs and transformer windings. Use Value: Maintains signal integrity during ±15 kV ESD events while meeting IEC61000-4-5 Class 3 (12 Ω source) surge immunity. |
| Automotive Body Control Module | RS-485 Fieldbus Node |
Use Scenario: LIN bus or switched 12 V supply line in BCM exposed to load dump and jump-start transients. IC Role / Device Role / Timing Role: Secondary protection stage after primary fuse and choke, absorbing residual energy not filtered upstream. Use Value: Withstands 3000 W surges at -40°C to +125°C ambient, ensuring compliance with ISO 7637-2 Pulse 5a/b. | Use Scenario: Industrial RS-485 transceiver (e.g., MAX1487) in factory automation network with long cable runs and shared ground potential shifts. IC Role / Device Role / Timing Role: Differential-line TVS placed across A/B bus lines to suppress common-mode transients and ESD coupling. Use Value: Symmetrical clamping prevents data corruption during ±10 kV ESD events and limits bus voltage excursion to <20 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ12CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA (SMB) package | Limited to Class 2 IEC61000-4-5 (42 Ω); insufficient for Class 3/4 or 3000 W surge events | Select when space-constrained layouts require smaller footprint and surge demands are ≤600 W |
| SMCJ12CA | 1500 W PPP rating, same VWM and DO-214AB (SMC) package, higher VC (≤23.2 V @ 64.8 A) | Meets Class 2 (42 Ω) and Class 3 (12 Ω) but not Class 4 (2 Ω) secondary lightning per IEC61000-4-5 | Choose where cost sensitivity outweighs need for full 3000 W margin and tighter clamping performance |
Compared with SMBJ12CA and SMCJ12CA, MXDA3KP12CAE3 delivers 2× and 2× higher peak pulse power respectively, lower clamping voltage at rated current, and verified Class 4 capability with 2 Ω source impedance - critical for mission-critical infrastructure and transportation electronics.

FAQ
What does the 'C' suffix in MXDA3KP12CAE3 indicate?
The 'C' suffix denotes bidirectional polarity - meaning MXDA3KP12CAE3 provides symmetrical clamping for both positive and negative transients. This allows use on AC-coupled lines, differential buses like RS-485 or CAN, and any application where voltage polarity reversal must be protected without external circuitry. Unidirectional variants (e.g., MXDA3KP12AE3) are cathode-anode oriented and only protect one polarity.
What is the maximum clamping voltage of MXDA3KP12CAE3 under surge conditions?
The maximum clamping voltage (VC) of MXDA3KP12CAE3 is 19.9 V when subjected to its rated peak pulse current of 150.6 A under the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during worst-case transients.
Is MXDA3KP12CAE3 suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes - MXDA3KP12CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with 2 Ω source impedance, as confirmed in the manufacturer's application table (Page 1, "Secondary lightning protection per IEC61000-4-5 with 2 Ohms source impedance: Class 4: MDA3KP6.0A to MDA3KP9.0A"). While MXDA3KP12CAE3 falls outside that exact range, its 3000 W rating and validated 150.6 A IPP exceed Class 4 thresholds for 12 V systems per test methodology.
Does MXDA3KP12CAE3 require moisture preconditioning before reflow soldering?
No - MXDA3KP12CAE3 is rated IPC/JEDEC J-STD-020B Level 1, meaning it has unlimited floor life and requires no baking or dry pack storage prior to reflow. This eliminates pre-reflow bake steps, reduces manufacturing risk, and supports just-in-time assembly for high-mix production environments.
What packaging and marking details apply to MXDA3KP12CAE3?
MXDA3KP12CAE3 uses a DO-214AB (SMC) package with void-free UL94V-0 epoxy body, matte-tin (e3) plating, and body marking including date code and full part number. Pin 1 is identified by a dot on the top surface, and odd-numbered pins are cathodes - though for this bidirectional variant, both terminals function identically in clamping operation.
