Product details
Overview
MXLDA3KP16CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, designed for high-reliability secondary lightning and ESD protection. It features a 16 V standoff voltage (VWM), 17.8–19.7 V breakdown range (V(BR)), 26.0 V max clamping voltage at 115.4 A peak pulse current, and operates from –55 °C to +150 °C - deployed in telecom power interfaces and industrial I/O protection circuits.
For engineers reviewing the MXLDA3KP16CAE3 datasheet, MXLDA3KP16CAE3 pinout, MXLDA3KP16CAE3 application, or MXLDA3KP16CAE3 equivalent, key selection criteria include bidirectional polarity, 10/1000 µs surge rating, RoHS-compliant matte-tin plating, MIL-PRF-19500 upscreening eligibility, and IEC61000-4-2/4-4/4-5 compliance for system-level transient immunity validation.
Technical Context
This TVS array uses silicon avalanche diode technology with sub-5 ns response time to clamp fast transients before downstream circuitry sustains damage. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal lines without polarity concerns.
The device is rated for 3000 W peak pulse power under 10/1000 µs waveform, with clamping voltage tightly specified at 26.0 V (max) at 115.4 A IPP - ensuring predictable overvoltage limiting during lightning-induced surges or inductive switching events in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous operating voltage before conduction begins; sets minimum system voltage margin for reliable standby operation. |
| V(BR) min–max | 17.8–19.7 V @ 1 mA - verified avalanche onset range ensures consistent turn-on behavior across production lots. |
| VC @ IPP | 26.0 V max @ 115.4 A - defines worst-case voltage seen by protected ICs during full-rated 10/1000 µs surge event. |
| PPP | 3000 W @ 10/1000 µs - quantifies energy-handling capability for IEC61000-4-5 Class 3/4 secondary lightning testing. |
| TJ range | –55 °C to +150 °C - supports deployment in extended-temperature industrial and aerospace applications without derating loss. |
| ID @ VWM | 2 µA max - ultra-low leakage preserves signal integrity and battery life in always-on monitoring circuits. |
Pinout & Package
MXLDA3KP16CAE3 is housed in a DO-214AB (SMC) plastic package with void-free UL94V-0 epoxy body, matte-tin-plated terminals, and polarity marked by a dot indicating Pin 1 (cathode for unidirectional variants; symmetric for bidirectional). Weight ≈ 5 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input terminal for negative-going transients | Connects to line under protection; forms one side of bidirectional clamping path. |
| Cathode (Pin 2) | Input terminal for positive-going transients | Connects to same line as Pin 1; completes symmetrical clamping loop for AC or floating signals. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled data lines or ungrounded buses without external polarity management. |
| 3000 W 10/1000 µs rating | Meets IEC61000-4-5 Class 4 requirements with 42 Ω source impedance for telecom and industrial port hardening. |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and wafer-level conformance inspection. |
| RoHS-compliant e3 marking | Matte-tin plating meets J-STD-020B Level 1 moisture sensitivity; no dry-pack required for SMT assembly. |
Applications
| Telecom Line Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting RS-485 transceivers and Ethernet PHYs against induced surges on outdoor copper runs. IC Role / Device Role / Timing Role: Bidirectional TVS array placed at connector entry point to shunt common-mode transients before signal conditioning stages. Use Value: Limits clamped voltage to ≤26.0 V during 115.4 A surges, preserving ±10 V input range of isolated ADC drivers and preventing latch-up in transceivers. | Use Scenario: Safeguarding 4–20 mA current-loop sensor inputs in factory automation cabinets exposed to relay coil kickback. IC Role / Device Role / Timing Role: Primary overvoltage clamp on field-side analog front-end, coordinated with series current-limiting resistor and filter capacitor. Use Value: Sub-5 ns response captures fast inductive spikes before op-amp input stages saturate, maintaining measurement accuracy during switching events. |
| Automotive Body Control Module (BCM) Power Bus | Medical Patient Monitoring ECG Lead Interface |
Use Scenario: Suppressing load-dump and jump-start transients on 12 V supply rails feeding microcontrollers and CAN transceivers. IC Role / Device Role / Timing Role: Secondary protection device downstream of primary fuse and upstream of DC-DC converters and LDOs. Use Value: Withstands 3000 W surges while maintaining <2 µA leakage at 16 V, avoiding false resets or brownouts in safety-critical modules. | Use Scenario: Shielding low-noise instrumentation amplifiers from ESD events during patient electrode connection/disconnection. IC Role / Device Role / Timing Role: First-stage transient limiter on differential ECG lead inputs, preceding high-pass filtering and gain stages. Use Value: Clamps human-body-model (HBM) ESD pulses to <26 V within nanoseconds, preventing amplifier saturation and baseline wander in diagnostic-grade waveforms. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | 600 W PPP rating; same VWM and bidirectional polarity; DO-214AA package (smaller footprint). | Limited to Class 2 IEC61000-4-5; insufficient for 3000 W lightning test requirements. | Select when space-constrained layouts prioritize footprint over surge margin. |
| SMCJ16CA | 1500 W PPP; identical DO-214AB package; same VWM and clamping profile but lower IPP (82.5 A). | Valid for Class 3 secondary lightning only; requires parallel devices for Class 4 compliance. | Choose where cost optimization is critical and full 3000 W rating is not mandated by end-equipment standards. |
Compared with SMBJ16CA and SMCJ16CA, MXLDA3KP16CAE3 delivers 2× and 2× higher peak pulse power respectively - enabling single-device compliance with IEC61000-4-5 Class 4 at 42 Ω, eliminating layout complexity from paralleling or cascading TVS arrays.

FAQ
What does the 'C' suffix in MXLDA3KP16CAE3 indicate?
The 'C' suffix denotes bidirectional polarity - meaning MXLDA3KP16CAE3 provides symmetrical clamping for both positive and negative transients without requiring external polarity configuration. This makes MXLDA3KP16CAE3 ideal for protecting AC-coupled interfaces like RS-485, CAN, or audio lines where voltage swings occur in both directions relative to ground.
Is MXLDA3KP16CAE3 compliant with IEC61000-4-5 Class 4 testing?
Yes, MXLDA3KP16CAE3 is rated for 3000 W peak pulse power under 10/1000 µs waveform and explicitly qualified for IEC61000-4-5 Class 4 secondary lightning testing with 42 Ω source impedance per the manufacturer's application guidance. Its 26.0 V clamping voltage at 115.4 A ensures protected circuitry remains within safe operating limits during full-level surge events.
What is the maximum junction temperature rating for MXLDA3KP16CAE3?
MXLDA3KP16CAE3 has a specified junction and storage temperature range of –55 °C to +150 °C. This wide thermal envelope allows MXLDA3KP16CAE3 to operate reliably in under-hood automotive environments, outdoor telecom enclosures, and industrial control cabinets without thermal derating below its full 3000 W surge rating until ambient exceeds 125 °C.
Does MXLDA3KP16CAE3 require dry-pack handling per J-STD-020B?
No, MXLDA3KP16CAE3 is classified as Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B due to its void-free thermosetting epoxy body and matte-tin plating. Therefore, MXLDA3KP16CAE3 may be stored and processed indefinitely at ambient conditions without baking or dry-pack requirements - simplifying SMT manufacturing flow and reducing handling risk.
Can MXLDA3KP16CAE3 be used for ESD protection per IEC61000-4-2?
Yes, MXLDA3KP16CAE3 is explicitly validated for ESD protection per IEC61000-4-2, leveraging its <5 ns response time and low clamping voltage. When placed at board-level entry points, MXLDA3KP16CAE3 limits contact discharge events to ≤26.0 V, safeguarding sensitive interface ICs such as USB transceivers, HDMI receivers, and touch controllers from latch-up or gate oxide damage.
