Product details
Overview
MXLDA3KP10CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability secondary lightning and ESD protection. It features a 10 V reverse standoff voltage (VWM), 11.1–12.3 V breakdown voltage (V(BR)), 17.0 V maximum clamping voltage (VC) at 176.4 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 MXLDA3KP10CAE3 datasheet, MXLDA3KP10CAE3 pinout, MXLDA3KP10CAE3 application, or MXLDA3KP10CAE3 equivalent, key selection criteria include bidirectional surge handling per IEC61000-4-5 (Class 1–4 with 2–42 Ω source impedance), 100 ps response time, RoHS-compliant e3 termination, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MXLDA3KP10CAE3 is a monolithic TVS array built using silicon avalanche technology, delivering sub-100 ps response to transients. Its bidirectional construction enables symmetrical clamping across both polarities without external polarity management, supporting protection of AC-coupled or differential signal lines.
It meets IEC61000-4-2 (ESD ±30 kV air/±30 kV contact), IEC61000-4-4 (EFT 4 kV), and IEC61000-4-5 (lightning surge up to 4 kA with 42 Ω source). Clamping performance is specified at 10/1000 μs waveform with 3000 W peak pulse power and full surge testing per lot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous operating voltage before clamping begins; matches 9–10 V DC bus or RS-485 common-mode range. |
| V(BR) min/max | 11.1–12.3 V - Confirmed avalanche onset window at 1 mA; ensures predictable turn-on margin above VWM. |
| VC @ IPP | 17.0 V - Clamping voltage at 176.4 A peak pulse; limits downstream IC stress during 10/1000 μs surges. |
| PPP | 3000 W - Peak pulse power rating at 10/1000 μs; supports Class 4 lightning immunity per IEC61000-4-5. |
| TJ range | −55 °C to +150 °C - Extended junction temperature range enables use in under-hood automotive or industrial enclosures. |
| Response time | <100 ps - Near-instantaneous avalanche response; protects against fast-rising ESD events without delay. |
| RoHS | e3 - Matte-tin termination compliant with RoHS Directive 2011/65/EU; no lead or hazardous substance exemptions. |
Pinout & Package
MXLDA3KP10CAE3 uses a 3-pin surface-mount package (case outline per RF01243, Page 6), with Pin 1 marked by a dot on top. Odd-numbered pins are cathodes; even-numbered pins are anodes. The device is bidirectional, so Pins 1 and 3 serve as symmetrical terminals for differential or AC line protection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Bidirectional terminal) | Common reference point for symmetrical clamping; connects to protected line or ground return path. |
| Pin 2 | Anode (Center tap) | Internal connection point shared between two back-to-back avalanche junctions; not externally accessible. |
| Pin 3 | Cathode (Bidirectional terminal) | Second symmetrical terminal; used with Pin 1 to clamp differential transients across a pair of lines. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, RS-485 buses, or transformer-coupled interfaces without polarity awareness. |
| 3000 W 10/1000 μs rating | Supports IEC61000-4-5 Class 4 surge immunity (4 kA) with 42 Ω source when used in parallel configurations or with appropriate PCB layout. |
| MIL-PRF-19500 screening option | Allows wafer-level traceability, lot norm screening on ID, and conformance inspection for aerospace and defense programs. |
| Level 1 moisture sensitivity | No dry pack or baking required prior to reflow; compatible with standard J-STD-020B assembly processes. |
| UL94V-0 epoxy body | Self-extinguishing thermoset encapsulation meets flammability safety requirements for industrial and telecom equipment. |
Applications
| Telecom Line Interface Protection | Industrial RS-485 Transceiver Protection |
|---|---|
Use Scenario: Protecting DSL or POTS line interface ICs from induced surges and lightning-induced transients on twisted-pair copper lines. IC Role / Device Role: Bidirectional TVS placed across differential line pair (TIP/RING) to clamp common-mode and differential-mode surges. Use Value: Limits clamping voltage to 17.0 V during 4 kA surges, preserving integrity of ±12 V RS-485 transceivers and isolators. | Use Scenario: Safeguarding factory automation PLCs and motor drives communicating over long-distance RS-485 networks exposed to switching noise and ground potential differences. IC Role / Device Role: Primary surge suppression element at bus connector, shunting transients before they reach transceiver input pins. Use Value: Withstands 3000 W pulses and maintains <5 ns response, preventing latch-up or damage to SN65HVD7x-series transceivers. |
| Automotive Body Control Module I/O | Medical Equipment Sensor Interface Protection |

IC Role / Device Role: Secondary protection stage after primary LC filtering, absorbing residual energy from fast-rising transients. Use Value: −55 °C to +150 °C operation and MIL-PRF-19500 screening support AEC-Q200-aligned reliability for automotive Tier-1 suppliers. | Use Scenario: Shielding analog front-end inputs of patient monitoring devices (ECG, SpO₂) from ESD events during clinical handling and cable coupling. IC Role / Device Role: Low-leakage (5 µA max ID) TVS placed directly at connector to prevent false triggering or ADC saturation. Use Value: 100 ps response and 17.0 V clamping ensure sensor signal integrity remains intact during ±30 kV contact ESD per IEC61000-4-2. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | 600 W PPP rating; same 10 V VWM and bidirectional configuration but lower surge capacity. | Not suitable for IEC61000-4-5 Class 4; limited to Class 1–2 or ESD/EFT-only environments. | Select SMBJ10CA only when board space is constrained and peak surge current stays below 50 A. |
| SMCJ10CA | 1500 W PPP rating; identical package footprint and pinout but half the power handling of MXLDA3KP10CAE3. | Meets Class 3 lightning with 12 Ω source, but fails Class 4 compliance at 42 Ω source impedance. | Choose SMCJ10CA for cost-sensitive industrial designs where 3000 W headroom is unnecessary. |
Compared with SMBJ10CA and SMCJ10CA, MXLDA3KP10CAE3 delivers double the surge power margin and verified Class 4 lightning immunity - critical for telecom infrastructure and harsh-environment control systems requiring field-reliability validation.

FAQ
What does the "C" suffix in MXLDA3KP10CAE3 indicate?
The "C" suffix denotes bidirectional construction - meaning MXLDA3KP10CAE3 provides symmetrical clamping for both positive and negative transients without polarity dependence. This makes it ideal for protecting AC-coupled lines, differential buses like RS-485, or transformer-isolated interfaces where voltage polarity reverses during normal operation.
Is MXLDA3KP10CAE3 suitable for IEC61000-4-5 Class 4 lightning protection?
Yes - MXLDA3KP10CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, delivering 3000 W peak pulse power at 10/1000 μs. Its 17.0 V clamping voltage at 176.4 A ensures downstream circuitry remains within safe operating limits during worst-case surge events.
What is the maximum standby leakage current ID for MXLDA3KP10CAE3 at rated VWM?
The maximum standby current ID for MXLDA3KP10CAE3 is 5 µA at its 10 V rated standoff voltage (VWM), measured at 25 °C. This low leakage preserves signal integrity in high-impedance sensor or precision analog paths while maintaining robust surge readiness.
Does MXLDA3KP10CAE3 require special handling for moisture sensitivity?
No - MXLDA3KP10CAE3 is rated IPC/JEDEC J-STD-020B Level 1, meaning it has unlimited floor life and requires no dry pack or baking before reflow soldering. Its void-free UL94V-0 epoxy body and matte-tin (e3) terminations support standard automated assembly processes.
Can MXLDA3KP10CAE3 be used in automotive applications?
Yes - MXLDA3KP10CAE3 operates from −55 °C to +150 °C and supports optional MIL-PRF-19500 upscreening, making it suitable for under-hood and body control module applications. While not AEC-Q200 certified out-of-box, its thermal and surge performance aligns with automotive transient immunity requirements including ISO 7637-2 Pulse 5.
