Product details
Overview
MXDA3KP14CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability 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 14 V reverse standoff voltage (VWM), 15.6–17.2 V breakdown voltage (V(BR)), and 23.2 V maximum clamping voltage (VC) at 129.4 A peak pulse current (IPP).
For engineers reviewing the MXDA3KP14CA datasheet, MXDA3KP14CA pinout, MXDA3KP14CA application, or MXDA3KP14CA equivalent, this device serves as a RoHS-compliant, MIL-PRF-19500 upscreenable TVS for industrial power supplies, telecom interfaces, and automotive ECUs requiring robust surge immunity with <5 ns response time and 100% surge-tested lot traceability.
Technical Context
The MXDA3KP14CA is a bidirectional TVS diode array optimized for fast transient suppression across AC-coupled or differential signal lines. Its sub-5 ns response time enables effective clamping of ESD events before downstream circuitry sustains damage, while its 3000 W peak pulse power rating (10/1000 µs waveform) supports compliance with Class 1–4 secondary lightning tests under multiple source impedances.
It operates over –55 °C to +150 °C junction temperature, uses void-free UL94V-0 epoxy packaging, and maintains ≤2 µA standby current (ID) at 14 V VWM. Polarity is defined by odd-numbered pins as cathodes, and it undergoes 3σ lot norm screening on ID and full surge testing per production lot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 14 V - Maximum continuous operating voltage without leakage exceeding 2 µA; sets minimum system working voltage margin. |
| V(BR) min/max | 15.6–17.2 V - Breakdown occurs within this range at 1 mA; ensures predictable turn-on during transients. |
| VC @ IPP | 23.2 V at 129.4 A - Clamped voltage seen by protected circuit during worst-case 10/1000 µs surge; defines safe voltage ceiling. |
| PPP | 3000 W - Peak pulse power handling capability under standard 10/1000 µs waveform; determines survivability against lightning surges. |
| Response time | <5 ns - Time from 0 V to V(BR) min; enables protection against ESD (IEC61000-4-2) and fast EFT bursts. |
| TJ/TSTG | –55 to +150 °C - Operating and storage temperature range; supports deployment in under-hood automotive and industrial environments. |
| RoHS | e3 - Lead-free matte-tin plating compliant with EU RoHS Directive 2011/65/EU; suitable for lead-free reflow assembly. |
Pinout & Package
MXDA3KP14CA uses a 3-pin surface-mount package (case outline per RF01243, Page 6) with void-free UL94V-0 epoxy body, tin-lead or matte-tin terminations, and polarity marked by a dot indicating Pin 1. Odd-numbered pins are cathodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connected to protected line side; clamps positive transients to ground when referenced to Pin 2. |
| Pin 2 | Anode/Common | Shared anode node; ties both channels to common reference (e.g., ground or return path). |
| Pin 3 | Cathode of Channel 2 | Connected to second protected line; enables bidirectional clamping across differential or AC-coupled pairs. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetrical clamping on AC or differential lines without polarity constraints; eliminates need for dual unidirectional devices. |
| 3000 W peak pulse power | Supports IEC61000-4-5 Class 4 lightning testing with 42 Ω source impedance; exceeds typical industrial surge requirements. |
| MIL-PRF-19500 upscreening option | Available with wafer/assembly lot traceability and extended reliability screening-critical for aerospace and defense applications. |
| Moisture sensitivity Level 1 | No dry pack required per IPC/JEDEC J-STD-020B; simplifies SMT handling and eliminates bake-out prior to reflow. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ14CA | 600 W PPP rating, same VWM and bidirectional configuration; smaller SMB package (vs. MDA's larger case). | Limited to Class 1–2 IEC61000-4-5; insufficient for Class 4 lightning with 42 Ω source. | Select when space-constrained and surge energy ≤600 W; verify derating at elevated temperatures. |
| SMCJ14CA | 1500 W PPP, same VWM and polarity; SMC package with higher thermal mass than SMB but lower than MDA. | Meets Class 3 lightning (42 Ω), but fails Class 4; not qualified to MIL-PRF-19500 screening levels. | Choose for cost-sensitive industrial designs where 3000 W headroom is unnecessary and upscreening is not required. |
Compared with SMBJ14CA and SMCJ14CA, MXDA3KP14CA delivers double the pulse power margin of SMCJ14CA and five times that of SMBJ14CA-enabling single-device Class 4 lightning compliance and long-term reliability in mission-critical systems where surge repetition and thermal cycling are dominant failure modes.

FAQ
What is the clamping voltage of MXDA3KP14CA at its rated peak pulse current?
The MXDA3KP14CA has a maximum clamping voltage (VC) of 23.2 V at its rated peak pulse current (IPP) of 129.4 A under 10/1000 µs waveform conditions. This value is guaranteed per the manufacturer's electrical characteristics table and defines the upper voltage limit imposed on protected circuits during worst-case surge events. The MXDA3KP14CA maintains this clamping performance across its full operating temperature range.
Is MXDA3KP14CA suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MXDA3KP14CA is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse power rating and 23.2 V clamping voltage ensure compliance when applied with proper PCB layout and grounding. MXDA3KP14CA also supports Class 4 under 12 Ω and 2 Ω source impedances per documented test configurations.
Does MXDA3KP14CA require dry packing or baking before SMT assembly?
No, MXDA3KP14CA has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions without dry pack and does not require baking prior to reflow soldering. This simplifies manufacturing logistics and eliminates yield loss from moisture-related popcorning. The MXDA3KP14CA's void-free epoxy body contributes to this robust MSL rating.
What is the polarity configuration of MXDA3KP14CA and how is it marked?
MXDA3KP14CA is a bidirectional TVS array with odd-numbered pins (Pin 1 and Pin 3) serving as cathodes and Pin 2 as the common anode. Polarity is physically indicated by a dot on the top surface of the package denoting Pin 1. This configuration allows symmetrical clamping across differential or AC-coupled signal paths without external biasing, and is clearly defined in the Mechanical and Packaging section of the RF01243 datasheet.
Can MXDA3KP14CA be used for ESD protection per IEC61000-4-2?
Yes, MXDA3KP14CA is specified for ESD protection per IEC61000-4-2 due to its <5 ns response time and ability to clamp multi-kilovolt discharges without degradation. Its sub-100 ps turn-on latency ensures effective suppression before sensitive transceivers or microcontrollers experience overstress. The MXDA3KP14CA's low standby current (≤2 µA at 14 V) further prevents interference with normal signal operation during non-event conditions.
