Product details
Overview
MXLDA3KP10AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 10 V standoff voltage (VWM), 11.1–12.3 V breakdown voltage (V(BR)), and 17.0 V clamping voltage (VC) at 176.4 A peak pulse current. It provides secondary lightning protection per IEC61000-4-5 (42 Ω, Class 1–4), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in power supply input stages.
For engineers reviewing the MXLDA3KP10AE3 datasheet, MXLDA3KP10AE3 pinout, MXLDA3KP10AE3 application, or MXLDA3KP10AE3 equivalent, key selection criteria include its 10 V working voltage rating, 176.4 A surge capability at 10/1000 µs, RoHS-compliant e3 termination, and verified performance under MIL-PRF-19500 high-reliability screening options.
Technical Context
This TVS array uses silicon avalanche diode technology to clamp transients within <100 ps response time. Its unidirectional polarity defines odd-numbered pins as cathodes, enabling precise placement in DC-biased protection paths such as telecom power inputs or industrial PLC front-ends.
The device operates across –55 °C to +150 °C junction temperature range and maintains 3000 W peak pulse power rating at 25 °C, derating linearly above 25 °C per Figure 3. Standby leakage is limited to ≤5 µA at 10 V VWM, supporting low-power system monitoring circuits without loading effects.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 11.1–12.3 V @ 1 mA - Ensures reliable triggering before downstream IC damage thresholds |
| VC @ IPP | 17.0 V @ 176.4 A - Clamped voltage during worst-case 10/1000 µs surge, limiting stress on protected circuitry |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy surges common in industrial mains interfaces and telecom line cards |
| ID @ VWM | ≤5 µA - Negligible standby current for battery-backed or ultra-low-power monitoring systems |
| TJ/TSTG | –55 to +150 °C - Supports operation in extended-temperature environments including automotive under-hood and outdoor base stations |
Pinout & Package
MXLDA3KP10AE3 is housed in a void-free transfer-molded thermosetting epoxy package (UL94V-0 rated), weighing ~5 g. Pin 1 is marked by a dot on top of the body; odd-numbered pins are cathodes per unidirectional construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected circuit's positive rail; clamps transients to ground when voltage exceeds V(BR) |
| Pin 2 | Anode | Connected to system ground; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables single-device protection against IEC61000-4-5 Class 4 surges (4 kV, 42 Ω source) without parallel staging |
| RoHS-compliant e3 termination | Matte-tin plating ensures solderability per MIL-STD-750 Method 2026 and eliminates lead-based process constraints |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring wafer lot traceability, 3σ ID screening, and surge testing per military standard |
| Moisture sensitivity Level 1 | No dry pack required per IPC/JEDEC J-STD-020B - simplifies handling and eliminates bake-out prior to reflow |
Applications
| Telecom Power Input Protection | Industrial PLC Digital I/O Protection |
|---|---|
Use Scenario: Protecting 12 V DC power rails in VoIP gateways and DSLAM line cards from induced surges and lightning-induced transients. IC Role / Device Role / Timing Role: Primary clamping element placed between input connector and DC-DC converter input, absorbing energy before it reaches sensitive regulation circuitry. Use Value: Limits clamped voltage to 17.0 V during 176.4 A surges, preventing latch-up or burnout in upstream rectifiers and filter capacitors. | Use Scenario: Safeguarding 24 V digital input modules in programmable logic controllers exposed to inductive kickback from solenoid valves and contactors. IC Role / Device Role / Timing Role: Unidirectional TVS connected anode-to-ground, cathode-to-signal line, suppressing negative-going transients while blocking normal operating voltage. Use Value: Responds in <100 ps to clamp fast-rising transients, maintaining signal integrity and eliminating false triggering of input latches. |
| Automotive Body Control Module (BCM) Power Rail | Medical Imaging Equipment Power Entry |
Use Scenario: Securing 12 V battery-fed power distribution networks in BCMs against load dump and jump-start transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Front-end TVS on main power bus, positioned ahead of fuse and pre-regulator, acting as first-line energy diversion device. Use Value: Withstands 3000 W pulses and operates up to +150 °C, meeting under-hood thermal requirements while protecting downstream CAN transceivers and microcontrollers. | Use Scenario: Shielding AC/DC power entry points in MRI and CT scanner subsystems from EFT bursts and electrostatic discharge during service access. IC Role / Device Role / Timing Role: Mounted directly at chassis entry point, shunting transients to earth ground before they propagate into isolated medical-grade power supplies. Use Value: 5 µA max leakage at 10 V VWM prevents interference with precision analog sensor biasing and ensures compliance with IEC60601-1-2 immunity requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | 600 W PPP rating, SMA package, 17.0 V VC @ 32.4 A IPP - lower surge capacity and smaller footprint | Best suited for space-constrained consumer electronics with lower surge exposure (IEC61000-4-2 only) | Select SMAJ10A only if system-level surge testing confirms ≤600 W threat level and PCB layout cannot accommodate larger MDA package |
| SMCJ10A | 1500 W PPP rating, SMC package, 17.0 V VC @ 87.2 A IPP - mid-tier power handling, same clamping voltage | Appropriate for industrial controls with moderate lightning risk (IEC61000-4-5 Class 2, 42 Ω) | Choose SMCJ10A when cost sensitivity outweighs need for full 3000 W margin but higher reliability than SMAJ series is required |
Compared with SMAJ10A and SMCJ10A, MXLDA3KP10AE3 delivers double the surge energy absorption of SMCJ10A and five times that of SMAJ10A - critical for infrastructure-grade equipment where single-point failure must be avoided and field return rates are tightly controlled.

FAQ
What is the clamping voltage of MXLDA3KP10AE3 at its rated peak pulse current?
The MXLDA3KP10AE3 has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPP) of 176.4 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 circuitry during worst-case surge events.
Is MXLDA3KP10AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP10AE3 is RoHS compliant. The 'e3' suffix denotes matte-tin plating per JEDEC standards, confirming lead-free terminations and compliance with Directive 2011/65/EU. This plating also meets MIL-STD-750 Method 2026 for solderability and supports Pb-free reflow profiles without degradation.
Does MXLDA3KP10AE3 support high-reliability screening per MIL-PRF-19500?
Yes, MXLDA3KP10AE3 qualifies for optional MIL-PRF-19500 upscreening, including wafer lot traceability, 3σ screening on standby current (ID), and full surge testing. While the base part is qualified to commercial standards, the screening options are documented in Micronote 129 and available upon request for aerospace and defense programs.
What is the maximum operating temperature range for MXLDA3KP10AE3?
MXLDA3KP10AE3 operates across a junction and storage temperature range of –55 °C to +150 °C. This extended range enables deployment in harsh environments such as automotive under-hood locations, outdoor telecom cabinets, and industrial motor drive enclosures where ambient temperatures exceed standard commercial limits.
How does the unidirectional configuration of MXLDA3KP10AE3 affect its circuit placement?
The unidirectional configuration of MXLDA3KP10AE3 requires cathode connection to the protected line and anode to ground, allowing it to block reverse voltage during normal operation while clamping positive transients. This makes MXLDA3KP10AE3 ideal for DC-biased applications like 12 V or 24 V power rails, unlike bidirectional variants used in AC or differential signal lines.
