Product details
Overview
MXLDA3KP14AE3 from Microsemi (now Microchip) is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 14 V 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. 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 inputs.
For engineers reviewing the MXLDA3KP14AE3 datasheet, MXLDA3KP14AE3 pinout, MXLDA3KP14AE3 application, or MXLDA3KP14AE3 equivalent, key selection criteria include its 14 V working voltage, sub-100 ps response time, RoHS-compliant e3 marking, MIL-PRF-19500 upscreening capability, and compatibility with high-reliability industrial and aerospace power rail protection designs.
Technical Context
The MXLDA3KP14AE3 operates as a unidirectional avalanche diode-based TVS array, designed for parallel connection across DC power rails to clamp transient overvoltages before they reach downstream ICs. Its junction temperature range of –55 °C to +150 °C and 10/1000 µs surge rating support operation in harsh environments including avionics and industrial control systems.
It features a thermoset epoxy package rated UL94V-0, tin-lead or matte-tin terminations compliant with MIL-STD-750 Method 2026, and polarity defined by odd-numbered pins as cathodes. Standby leakage current is limited to ≤2 µA at 14 V, ensuring minimal power loss in standby mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff Voltage) | 14 V - Maximum continuous DC or peak AC voltage the device blocks without conduction. |
| V(BR) Min/Max | 15.6–17.2 V @ I(BR) = 1 mA - Ensures reliable avalanche initiation within tight tolerance for consistent clamping onset. |
| VC @ IPP | 23.2 V @ 129.4 A - Clamped voltage during worst-case 10/1000 µs surge; defines maximum stress on protected circuitry. |
| PPP | 3000 W @ 10/1000 µs - Peak power handling capacity under standardized surge waveform; validates robustness against lightning-induced transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14A | Lower PPP (400 W), same VWM (14 V), DO-214AC package, no MIL screening option. | Targeted at commercial-grade consumer electronics; insufficient for IEC61000-4-5 Class 4 or aerospace use. | Select SMAJ14A only for cost-sensitive, non-safety-critical 14 V rail protection where surge energy is below 500 W. |
| SMCJ14A | Same package (DO-214AB), 1500 W PPP, V(BR) 15.6–17.2 V, no upscreening path per MIL-PRF-19500. | Valid for industrial IEC61000-4-5 Class 2–3 but not Class 4; lacks lot traceability and 3σ ID screening. | Choose SMCJ14A for mid-tier industrial applications requiring higher surge margin than SMAJ but without military qualification needs. |
Compared with SMAJ14A and SMCJ14A, MXLDA3KP14AE3 delivers 2× and 2× higher peak pulse power respectively, supports MIL-PRF-19500 upscreening, and maintains identical VWM/V(BR) specs-making it the sole option for Class 4 lightning immunity and high-reliability deployments.

FAQ
What is the clamping voltage of MXLDA3KP14AE3 at its rated peak pulse current?
The MXLDA3KP14AE3 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 circuitry during surge events. The MXLDA3KP14AE3 achieves this clamping performance while maintaining low leakage (<2 µA) and fast response (<100 ps), making it suitable for protecting sensitive 14 V nominal systems.
Is MXLDA3KP14AE3 RoHS-compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP14AE3 is RoHS-compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide. The 'e3' designation specifies annealed matte-tin plating meeting JEDEC/IPC standards and full compliance with Directive 2011/65/EU, including lead content <1000 ppm. This ensures compatibility with lead-free reflow processes and eliminates hazardous substance concerns in final product certification for MXLDA3KP14AE3.
Can MXLDA3KP14AE3 be used for bidirectional transient protection?
No, MXLDA3KP14AE3 is a unidirectional TVS device, as indicated by the absence of a 'C' suffix in its part number (e.g., MDA3KP14CA would be bidirectional). Its internal structure connects two cathodes to pins 1 and 3 with a shared anode at pin 2, enabling clamping only for positive transients relative to ground. For bidirectional protection, a separate part such as MXLDA3KP14CE3 must be selected, as MXLDA3KP14AE3 does not conduct or clamp during negative-going surges.
What is the maximum operating temperature range for MXLDA3KP14AE3?
The MXLDA3KP14AE3 is rated for junction and storage temperatures from –55 °C to +150 °C, per its Absolute Maximum Ratings table. This extended range allows deployment in under-hood automotive ECUs, downhole oilfield tools, and avionics power modules where ambient temperatures exceed standard commercial limits. Derating curves in the datasheet confirm usable 3000 W surge capability down to –40 °C ambient, and the MXLDA3KP14AE3 maintains specified VWM and VC performance across the full range.
Does MXLDA3KP14AE3 require special PCB layout considerations?
Yes, MXLDA3KP14AE3 requires low-inductance PCB layout to preserve its <100 ps response: short, wide traces between pins 1/3 and the protected line, direct connection of pin 2 to low-impedance ground plane, and avoidance of vias in the surge current path. The datasheet specifies a recommended pad layout on page 7 to minimize parasitic inductance. Proper implementation ensures the MXLDA3KP14AE3 clamps transients before voltage overshoot damages downstream ICs-critical for achieving its rated 23.2 V VC performance.
