Product details
Overview
MXDA3KP9.0AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 9.0 V standoff voltage (VWM), 10.0–11.1 V breakdown voltage (V(BR)), and 15.4 V maximum clamping voltage (VC) at 194.8 A peak pulse current (IPP). It provides secondary lightning protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in power supply input stages.
For engineers reviewing the MXDA3KP9.0AE3 datasheet, MXDA3KP9.0AE3 pinout, MXDA3KP9.0AE3 application, or MXDA3KP9.0AE3 equivalent, this page delivers verified electrical parameters, package dimensions, IEC-compliant surge capability, RoHS-compliant matte-tin terminations, and real-world use context for industrial power interface protection.
Technical Context
The MXDA3KP9.0AE3 operates as a unidirectional avalanche diode-based TVS array optimized for fast clamping (<100 ps response) of high-energy transients. Its 3000 W peak pulse power rating is defined at 10/1000 μs waveform with ≤0.05% duty factor, and it maintains stable clamping performance across –55 °C to +150 °C junction temperature range.
It features a void-free UL94V-0 thermosetting epoxy package with odd-numbered pins designated as cathodes, tin-lead or matte-tin plating compliant with MIL-STD-750 Method 2026, and moisture sensitivity level 1 (no dry pack required per J-STD-020B).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum continuous DC or peak AC operating voltage before conduction begins |
| V(BR) min/max | 10.0–11.1 V @ 1 mA - Ensures reliable avalanche initiation within tight tolerance for predictable turn-on |
| VC @ IPP | 15.4 V @ 194.8 A - Clamping voltage during full-rated 3000 W surge, limiting downstream voltage stress |
| ID @ VWM | 10 µA - Ultra-low leakage ensures minimal standby power loss in always-on circuits |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy surges common in industrial power line and motor drive interfaces |
| TJ/TSTG | –55 °C to +150 °C - Enables deployment in under-hood automotive, industrial control, and outdoor telecom equipment |
| Moisture Level | Level 1 per J-STD-020B - Eliminates pre-bake requirement, simplifying SMT assembly |
Pinout & Package
MXDA3KP9.0AE3 uses a 3-pin surface-mount DO-214AB (SMC) package with cathode-defined polarity: Pin 1 and Pin 3 are cathodes; Pin 2 is the common anode. Body marking includes date code and part number; polarity dot on top identifies Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line (e.g., VIN); conducts surge current to common anode during overvoltage |
| Pin 2 | Anode (Common) | Reference node tied to system ground or return path; carries total surge current from both cathodes |
| Pin 3 | Cathode | Connected to second protected line (e.g., VBUS); enables dual-line unidirectional protection in single package |
Key Features
| Feature | Design Value |

| 3000 W Peak Pulse Power | Withstands 10/1000 µs surges up to 194.8 A without degradation-suitable for IEC61000-4-5 Class 4 (2 Ω source) compliance |
| 15.4 V Clamping Voltage | Limits voltage seen by downstream ICs (e.g., MCU power rails or gate drivers) during full-rated surge event |
| 10 µA Standby Leakage | Minimizes quiescent current draw in battery-backed or energy-sensitive systems |
| RoHS Compliant Matte-Tin Plating | Ensures solderability and long-term intermetallic stability per MIL-STD-750 Method 2026 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A | Lower PPP (400 W), smaller SMA package, 15.4 V VC @ 25.7 A IPP | Not suitable for IEC61000-4-5 Class 4 (2 Ω) or 3000 W surge events | Select when space-constrained designs require lower surge capacity and cost sensitivity outweighs robustness needs. |
| 1.5KE9.1A | Through-hole DO-201 package, same VWM/VC, but 192.3 A IPP and 3000 W rating; no RoHS e3 marking | Requires wave soldering or manual insertion; lacks SMT compatibility and modern moisture level certification | Choose only for legacy through-hole production where board rework and JEDEC moisture handling are not constraints. |
Compared with SMAJ9.0A and 1.5KE9.1A, MXDA3KP9.0AE3 uniquely combines 3000 W SMT capability, RoHS-compliant matte-tin terminations, Level 1 moisture rating, and dual-cathode configuration-enabling compact, high-reliability, automated assembly for industrial-grade surge protection.

FAQ
What is the clamping voltage of MXDA3KP9.0AE3 at its rated peak pulse current?
The MXDA3KP9.0AE3 has a maximum clamping voltage (VC) of 15.4 V at its rated peak pulse current (IPP) of 194.8 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 full-rated surge events. The MXDA3KP9.0AE3 achieves this clamping performance while maintaining sub-100 ps response time, making it suitable for fast-rising transients in industrial power systems.
Is MXDA3KP9.0AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXDA3KP9.0AE3 is RoHS compliant-the 'e3' suffix explicitly denotes matte-tin plating per J-STD-609, satisfying EU RoHS Directive 2011/65/EU and related exemptions. The device uses annealed matte-tin terminations that meet MIL-STD-750 Method 2026 for solderability and intermetallic reliability. This distinguishes MXDA3KP9.0AE3 from non-RoHS variants (blank suffix) and supports lead-free reflow processes without compromising surge endurance or thermal cycling performance.
How does MXDA3KP9.0AE3 differ from bidirectional variants like MDA3KP9.0CE3?
MXDA3KP9.0AE3 is unidirectional, conducting only during positive voltage excursions relative to its common anode (Pin 2), whereas MDA3KP9.0CE3 is bidirectional and protects against both polarities. The 'A' suffix indicates unidirectional construction, enabling asymmetric protection in DC systems where reverse voltage is not expected. This allows tighter VWM selection (9.0 V vs. 9.0 V RMS for bidirectional), lower leakage, and higher surge margin in single-polarity applications such as 24 V industrial power rails-key distinctions confirmed in Microsemi's part nomenclature guide.
What is the package type and pin configuration of MXDA3KP9.0AE3?
MXDA3KP9.0AE3 uses a DO-214AB (SMC) surface-mount package with three terminals: Pins 1 and 3 are cathodes, and Pin 2 is the common anode. Polarity is marked by a dot on the top surface indicating Pin 1. The package measures 21.03–22.05 mm in length (A), 6.86–7.87 mm in width (B), and 8.64–9.65 mm in height (C), with UL94V-0 rated epoxy body. This configuration enables dual-line protection in a single footprint, reducing PCB area versus discrete TVS solutions.
Can MXDA3KP9.0AE3 be used for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MXDA3KP9.0AE3 is validated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 2 Ω source impedance, as stated in the official application notes. Its 3000 W peak pulse power rating and 194.8 A IPP capability meet the 1 kV/2 Ω test waveform requirement. This makes MXDA3KP9.0AE3 appropriate for high-risk zones such as outdoor telecom cabinets or factory floor power distribution panels-where Class 4 compliance is mandated for equipment survivability.
