Product details
Overview
MXDA3KP11AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 11 V standoff voltage (VWM), 12.2–13.5 V breakdown voltage (V(BR)), and 18.2 V maximum clamping voltage (VC) at 164.8 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 DC power rails.
For engineers reviewing the MXDA3KP11AE3 datasheet, MXDA3KP11AE3 pinout, MXDA3KP11AE3 application, or MXDA3KP11AE3 equivalent, key selection criteria include its 11 V working voltage, 18.2 V clamping performance at 164.8 A, RoHS-compliant e3 matte-tin plating, -55 °C to +150 °C junction temperature range, and UL94V-0 void-free epoxy package for high-reliability industrial and aerospace power input stages.
Technical Context
This TVS array uses silicon avalanche diode technology to clamp transients within <100 ps response time. It operates in unidirectional configuration with cathode-defined polarity (odd-numbered pins are cathodes), rated for 10/1000 µs waveform surge testing and fully surge-tested per lot.
Designed for vertical mounting on PCBs, it delivers 3000 W peak pulse power at 25 °C with derating above 25 °C per Figure 3. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required - and supports solder reflow up to 260 °C for 10 seconds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff Voltage) | 11 V - maximum continuous DC or peak AC voltage the device blocks without clamping |
| V(BR) Min/Max | 12.2 V / 13.5 V at I(BR) = 1 mA - defines reliable avalanche onset threshold for design margining |
| VC @ IPP | 18.2 V at 164.8 A - clamping voltage seen by protected circuit during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - peak transient energy absorption capability under standard surge waveform |
| ID @ VWM | 5 µA - leakage current at rated standoff voltage, critical for low-power standby circuits |
| TJ/TSTG Range | -55 °C to +150 °C - enables deployment in extended-temperature industrial, avionics, and downhole applications |
| RoHS Compliance | e3 - annealed matte-tin plating, lead-free, compliant with EU Directive 2011/65/EU |
Pinout & Package
MXDA3KP11AE3 uses a 3-pin SMC (DO-214AB) surface-mount package with cathode-defined polarity: Pin 1 and Pin 3 are cathodes; Pin 2 is the common anode. The package features void-free UL94V-0 thermosetting epoxy body, tin-lead or matte-tin plating, and dot marking for Pin 1 identification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connected to protected line (e.g., +12 V rail); clamps to common anode when overvoltage occurs |
| Pin 2 | Common Anode | Reference node tied to system ground or return path; forms bidirectional-capable structure when paired with Pin 3 |
| Pin 3 | Cathode of Channel 2 | Used for dual-line protection (e.g., differential bus or redundant supply); shares Pin 2 anode |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W Peak Pulse Power | Enables robust protection against IEC61000-4-5 Class 4 surges (4 kV, 42 Ω source) without degradation |
| <100 ps Response Time | Clamps ESD events before sensitive ICs experience latch-up or gate oxide damage |
| MIL-PRF-19500 Screening Option | Supports high-reliability qualification for aerospace and defense programs requiring wafer/lot traceability |
| UL94V-0 Epoxy Body | Provides flame-retardant mechanical integrity under sustained overvoltage or fault conditions |
| Level 1 Moisture Sensitivity | Eliminates baking requirement prior to reflow, reducing manufacturing cost and handling risk |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A | 600 W PPP rating, same VWM (11 V), but lower VC (18.2 V vs. 19.0 V) and IPP (102 A vs. 164.8 A) | Limited to Class 2/3 IEC61000-4-5; insufficient for Class 4 4 kV testing | Select SMBJ11A only for space-constrained designs where 3000 W surge capacity is not required. |
| 1.5KE11A | Through-hole TO-204AA package, same VWM/VC/IPP specs, but no RoHS e3 marking or MIL screening option | Not suitable for automated SMT lines; lacks moisture level 1 compliance and reflow compatibility | Choose 1.5KE11A only for legacy through-hole prototyping or repair where SMT is unavailable. |
Compared with SMBJ11A and 1.5KE11A, MXDA3KP11AE3 uniquely combines 3000 W surge capability, SMC surface-mount form factor, RoHS e3 plating, and optional MIL-PRF-19500 screening - making it the only choice for high-reliability, high-energy, production-ready SMT deployments.

FAQ
What is the clamping voltage of MXDA3KP11AE3 at its rated peak pulse current?
The MXDA3KP11AE3 has a maximum clamping voltage (VC) of 18.2 V at its rated peak pulse current (IPP) of 164.8 A under 10/1000 µs waveform conditions. This value is measured per Figure 2 in the official datasheet and represents the upper limit of voltage imposed on the protected circuit during worst-case surge events.
Does MXDA3KP11AE3 support bidirectional transient suppression?
No, MXDA3KP11AE3 is a unidirectional TVS array. Its part number suffix "A" (not "C") confirms unidirectional polarity. It clamps only positive transients relative to its common anode (Pin 2); for bidirectional protection, Microsemi offers the MXDA3KP11CE3 variant with "C" suffix.
What is the meaning of the "e3" suffix in MXDA3KP11AE3?
The "e3" suffix in MXDA3KP11AE3 indicates RoHS-compliant matte-tin plating per JEDEC Standard J-STD-609A. It specifies lead-free termination with annealed tin finish, qualified for Pb-free reflow soldering up to 260 °C for 10 seconds, and compliant with EU Directive 2011/65/EU.
Can MXDA3KP11AE3 be used for IEC61000-4-5 Class 4 lightning surge testing?
Yes, MXDA3KP11AE3 is rated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance. Its 3000 W peak pulse power and 164.8 A IPP capability meet the 4 kV test level requirements when applied to 11 V DC systems, as confirmed in the Applications section of the RF01243 datasheet.
What is the thermal derating behavior of MXDA3KP11AE3 above 25 °C?
MXDA3KP11AE3 follows a linear derating curve starting at 25 °C, where peak pulse power decreases to 50% at +125 °C and reaches zero at +150 °C. This derating is defined in Figure 3 of the RF01243 datasheet and must be applied when designing for continuous operation in high-ambient environments such as enclosed industrial enclosures or avionics bays.
