Product details
Overview
MXLDA3KP13CAE3 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 with 12 Ω and 42 Ω source impedances, ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient clamping. It features 13 V standoff voltage (VWM), 14.4–15.9 V breakdown range (V(BR)), 21.5 V max clamping voltage (VC) at 139.4 A IPP, and operates from –55 °C to +150 °C.
For engineers reviewing the MXLDA3KP13CAE3 datasheet, MXLDA3KP13CAE3 pinout, MXLDA3KP13CAE3 application, or MXLDA3KP13CAE3 equivalent, key selection criteria include bidirectional polarity, 13 V working voltage compatibility with 12 V rail systems, 3000 W peak pulse power rating at 10/1000 µs, and RoHS-compliant matte-tin termination per MIL-STD-750 Method 2026.
Technical Context
This TVS array uses silicon avalanche diode technology with void-free thermosetting epoxy encapsulation (UL94V-0). Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal lines, and its <5 ns response time ensures effective suppression of ESD (IEC61000-4-2), EFT (IEC61000-4-4), and lightning-induced surges (IEC61000-4-5).
The device is surge-tested per unit, rated for 3000 W peak pulse power at 10/1000 µs waveform, and supports high-reliability screening per MIL-PRF-19500. Standby current ID is ≤5 µA at VWM, and moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage; matches 12 V nominal DC rails with margin |
| V(BR) min–max | 14.4–15.9 V - guaranteed avalanche conduction onset range at 1 mA test current |
| VC @ IPP | 21.5 V - maximum clamping voltage during 139.4 A 10/1000 µs surge; limits downstream voltage stress |
| IPP | 139.4 A - peak impulse current capability at rated clamping voltage |
| PPP | 3000 W - peak pulse power handling at 10/1000 µs waveform |
| TJ/TSTG | –55 to +150 °C - extended industrial temperature range for under-hood or outdoor deployment |
| Polarity | Bidirectional - enables symmetric overvoltage protection on AC or differential lines without polarity concern |
Pinout & Package
MXLDA3KP13CAE3 is housed in a DO-214AB (SMC) surface-mount package with two terminals. Pin 1 (cathode for unidirectional variants) is marked by a dot on the top surface; for this bidirectional part, both terminals are functionally symmetrical. The package measures 8.64–9.65 mm × 6.86–7.87 mm × 21.03–22.05 mm (L×W×H) and weighs ~5 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Both terminals conduct equally in either direction during overvoltage events; no polarity-dependent layout required |
| Case | Thermal and mechanical interface | Void-free UL94V-0 epoxy body provides mechanical robustness and thermal dissipation path to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled interfaces (e.g., RS-485, CAN, Ethernet PHY) without external polarity management |
| 3000 W peak pulse rating | Withstands high-energy transients from lightning coupling or inductive load switching in industrial and telecom infrastructure |
| MIL-PRF-19500 screening option | Supports high-reliability programs requiring lot traceability, 3σ standby current screening, and wafer-level conformance inspection |
| RoHS-compliant e3 termination | Matte-tin plating ensures solderability per MIL-STD-750 Method 2026 and eliminates lead-based process requirements |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|
Use Scenario: Protection of 24 V DC input stages against inductive kickback from contactors and relay coils. IC Role / Device Role / Timing Role: Transient voltage suppressor placed across input terminals to clamp spikes before they reach upstream DC-DC converters.

IC Role / Device Role / Timing Role: Bidirectional TVS placed across A/B lines to suppress ESD and fast transients without disrupting differential signaling. Use Value: Sub-5 ns response time prevents data corruption during 8 kV contact ESD events per IEC61000-4-2, maintaining communication integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package (smaller footprint) | Limited to lower-energy transients; unsuitable for IEC61000-4-5 Class 3/4 or 3000 W surge events | Select when board space is constrained and surge threat level is limited to ESD/EFT only. |
| SMCJ13CA | 1500 W PPP rating, identical DO-214AB package, same VWM and bidirectional configuration | Half the peak pulse power; meets IEC61000-4-5 Class 1–2 but not Class 3 with 12 Ω source | Choose where cost optimization is prioritized and full 3000 W capability is not required by system specification. |
Compared with MXLDA3KP13CAE3, SMBJ13CA offers space savings at the cost of 80% lower surge energy handling, while SMCJ13CA retains the same footprint and polarity but delivers only 50% of the peak pulse power - making MXLDA3KP13CAE3 the sole option for full IEC61000-4-5 Class 3 compliance in 12 V systems.

FAQ
What does the "C" suffix in MXLDA3KP13CAE3 indicate?
The "C" suffix denotes bidirectional polarity - meaning MXLDA3KP13CAE3 provides symmetrical clamping for both positive and negative transients. This allows it to protect AC-coupled or floating signal paths without regard to voltage polarity, unlike unidirectional variants (e.g., MXLDA3KP13AE3) that clamp only in one direction.
Is MXLDA3KP13CAE3 compliant with IEC61000-4-5 for secondary lightning protection?
Yes, MXLDA3KP13CAE3 is validated for secondary lightning protection per IEC61000-4-5: it supports Class 1–3 with 12 Ω source impedance and Class 1–4 with 42 Ω source impedance. Its 3000 W peak pulse rating and 21.5 V clamping voltage ensure compliance when used with appropriate series impedance in the protected circuit.
What is the maximum clamping voltage of MXLDA3KP13CAE3 and at what current is it specified?
The maximum clamping voltage VC of MXLDA3KP13CAE3 is 21.5 V, measured at the peak impulse current IPP of 139.4 A under 10/1000 µs waveform conditions. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Does MXLDA3KP13CAE3 require dry-pack packaging due to moisture sensitivity?
No, MXLDA3KP13CAE3 has IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1, meaning it is not moisture-sensitive and does not require dry-pack packaging or baking prior to reflow soldering - simplifying manufacturing handling and reducing assembly risk.
What package type and termination does MXLDA3KP13CAE3 use?
MXLDA3KP13CAE3 uses the DO-214AB (SMC) surface-mount package with matte-tin (e3) termination, compliant with RoHS and solderable per MIL-STD-750 Method 2026. The package features a dot marking for terminal identification and void-free UL94V-0 epoxy encapsulation.
