Product details
Overview
MXDA3KP10AE3 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 maximum clamping voltage (VC) at 176.4 A peak pulse current (IPP). 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 DC power rails.
For engineers reviewing the MXDA3KP10AE3 datasheet, MXDA3KP10AE3 pinout, MXDA3KP10AE3 application, or MXDA3KP10AE3 equivalent, this device is selected for high-reliability 10 V DC rail protection where sub-100 ps response time, RoHS-compliant packaging, and MIL-PRF-19500 upscreening capability are required in aerospace, industrial control, and telecom infrastructure designs.
Technical Context
The MXDA3KP10AE3 operates as a unidirectional avalanche diode-based TVS array, designed to clamp transients within 100 ps of overvoltage onset. Its 10 V working standoff voltage ensures compatibility with standard 12 V nominal systems while maintaining margin against ripple and tolerance drift.
It delivers 3000 W peak pulse power at 10/1000 µs waveform, with clamping performance validated at 176.4 A IPP and 17.0 V VC - enabling robust protection of downstream MOSFETs, controllers, and interface ICs without sacrificing system-level surge immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff Voltage) | 10 V - maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) Min–Max | 11.1–12.3 V @ I(BR) - guaranteed avalanche initiation range, ensuring predictable turn-on above operating rail |
| VC @ IPP | 17.0 V @ 176.4 A - clamping voltage during worst-case 10/1000 µs surge, defining protected circuit's max stress level |
| PPP | 3000 W @ 10/1000 µs - peak transient energy absorption capacity under standardized surge waveform |
| ID @ VWM | 5 µA - leakage current at rated standoff, low enough to avoid loading 10 V bias networks |
| TJ Range | −55 °C to +150 °C - extended thermal envelope supporting operation in sealed enclosures or under-hood environments |
| RoHS | e3 suffix - lead-free matte-tin plating compliant with EU RoHS Directive 2011/65/EU |
Pinout & Package
MXDA3KP10AE3 uses a 3-pin SMD package (case outline per RF01243, Page 6), with pin 1 marked by a dot on top of the body. Odd-numbered pins (1 and 3) serve as cathodes; pin 2 is the common anode. The thermoset epoxy case meets UL94V-0 and weighs ~5 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Channel 1) | Connected to protected line 1 (e.g., VBUS); conducts when line exceeds V(BR) relative to common anode |
| Pin 2 | Common Anode | Reference node tied to system ground or return path; shared conduction path for both channels |
| Pin 3 | Cathode (Channel 2) | Connected to protected line 2 (e.g., signal pair); enables dual-line protection with single device |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W Peak Pulse Power | Enables compliance with IEC61000-4-5 Class 4 (42 Ω source) without derating at 25 °C |
| 100 ps Response Time | Clamps ESD events before sensitive logic or analog circuits experience overstress |
| MIL-PRF-19500 Screening Option | Supports high-reliability qualification for aerospace and defense programs requiring lot traceability and 3σ ID screening |
| UL94V-0 Epoxy Body | Self-extinguishing encapsulation prevents flame propagation in enclosed power systems |
| Level 1 Moisture Sensitivity | No dry-pack or baking required prior to reflow, reducing manufacturing overhead and handling risk |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|
Use Scenario: Protection of 12 V auxiliary control rails in variable-frequency drives exposed to inductive kickback from contactors and relays. IC Role / Device Role / Timing Role: Unidirectional TVS array clamping transients on dual isolated DC lines feeding gate drivers and isolation amplifiers. Use Value: Limits voltage excursions to ≤17.0 V during 3000 W surges, preserving gate oxide integrity and preventing false triggering of overvoltage lockout. | Use Scenario: Surge protection on −48 V DC telecom power distribution boards subject to lightning-induced surges per IEC61000-4-5. IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional array used across positive/negative rails with common-anode grounding strategy. Use Value: Delivers Class 4 immunity (4 kV, 42 Ω source) without parallel MOVs or additional crowbar circuitry. |
| Automotive ECUs | Medical Imaging Power Supplies |
Use Scenario: Input rail protection for engine control units operating in 12 V battery environments with load dump and jump-start transients. IC Role / Device Role / Timing Role: Primary clamping device on main 12 V input, placed upstream of DC/DC converters and microcontrollers. Use Value: Withstands 200 A forward surge (IFSM) and maintains <5 µA leakage at 10 V, minimizing standby power loss. | Use Scenario: Protection of high-stability ±15 V analog supply rails in MRI gradient amplifier modules susceptible to RF coupling and switching noise. IC Role / Device Role / Timing Role: Dual-channel TVS suppressing differential-mode transients between complementary rails referenced to chassis ground. Use Value: 17.0 V clamping ensures op-amp inputs remain within absolute maximum ratings during 10/1000 µs bursts up to 176.4 A. |
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, 10.0–11.1 V V(BR), 16.0 V VC @ 32.4 A IPP - lower power handling and current capacity | Targeted at consumer-grade 12 V interfaces; insufficient for IEC61000-4-5 Class 4 or MIL-PRF-19500 programs | Select SMAJ10A only for cost-sensitive, non-safety-critical applications with <1 kW surge exposure |
| SMCJ10A | 1500 W PPP rating, 10.0–11.1 V V(BR), 17.0 V VC @ 88.2 A IPP - half the peak power and current of MXDA3KP10AE3 | Valid for IEC61000-4-5 Class 2 (42 Ω) but not Class 4; lacks upscreening path and moisture Level 1 certification | Choose SMCJ10A when board space allows larger SMC package and full 3000 W rating is unnecessary |
Compared with SMAJ10A and SMCJ10A, MXDA3KP10AE3 provides double the surge current capacity and full Class 4 lightning immunity in a compact 3-pin SMD package with RoHS-compliant plating and optional high-reliability screening - making it the only choice for mission-critical 10 V rail protection where derating margin and qualification traceability are mandatory.

FAQ
What is the polarity configuration of MXDA3KP10AE3?
MXDA3KP10AE3 is a unidirectional TVS array with cathodes on pins 1 and 3 and a common anode on pin 2. This configuration allows clamping of positive transients on two independent lines relative to a shared ground reference. The "A" suffix in the part number explicitly denotes unidirectional polarity, distinguishing it from bidirectional variants like MXDA3KP10CE3.
Does MXDA3KP10AE3 meet IEC61000-4-5 Class 4 requirements?
Yes, MXDA3KP10AE3 meets IEC61000-4-5 Class 4 for secondary lightning protection 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 IPP ensures protected circuits remain within safe operating limits during the 4 kV test waveform, as confirmed in Microsemi's RF01243 datasheet Figure 1 and Applications section.
What is the maximum junction temperature rating for MXDA3KP10AE3?
The maximum junction temperature (TJ) for MXDA3KP10AE3 is +150 °C, with a minimum of −55 °C. This wide operating range supports deployment in under-hood automotive modules, sealed industrial enclosures, and outdoor telecom cabinets. Derating of peak pulse power begins above 25 °C per Figure 3 in the RF01243 datasheet.
Is MXDA3KP10AE3 compatible with lead-free reflow processes?
Yes, MXDA3KP10AE3 features annealed matte-tin plating (e3 RoHS-compliant) and is rated for solder temperatures up to 260 °C for 10 seconds, fully compatible with standard lead-free reflow profiles. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1, eliminating the need for dry packing or pre-baking before assembly.
Can MXDA3KP10AE3 be used for ESD protection per IEC61000-4-2?
Yes, MXDA3KP10AE3 is specified for ESD protection per IEC61000-4-2 due to its <100 ps response time and ability to clamp fast-rising transients. While optimized for higher-energy 10/1000 µs surges, its avalanche structure responds effectively to 8 kV contact and 15 kV air discharge events - as stated in the "DESCRIPTION" section of RF01243 Rev B.
