Product details
Overview
MXDA3KP7.0AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 7.0 V reverse standoff voltage (VWM), 7.78–8.6 V breakdown voltage (V(BR)), and 12.0 V maximum clamping voltage (VC) at 250 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 MXDA3KP7.0AE3 datasheet, MXDA3KP7.0AE3 pinout, MXDA3KP7.0AE3 application, or MXDA3KP7.0AE3 equivalent, key selection criteria include VWM ≥ system operating voltage, VC < protected IC's absolute maximum rating, IPP capability for expected surge energy, RoHS-compliant matte-tin termination, and UL94V-0 void-free epoxy package for high-reliability industrial and telecom power interfaces.
Technical Context
The MXDA3KP7.0AE3 operates as a unidirectional avalanche diode-based TVS, triggered when reverse voltage exceeds its 7.78–8.6 V breakdown range. Its sub-100 ps response time enables effective suppression of ESD events and fast transients before downstream components are stressed.
It is rated for 3000 W peak pulse power at 10/1000 µs waveform, with 250 A maximum peak pulse current (IPP) and 200 µA maximum standby current (ID) at 7.0 V. Thermal derating begins above 25 °C per Figure 3, maintaining safe operation up to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - Maximum continuous DC or peak AC voltage the device blocks without conduction; must exceed circuit operating voltage. |
| V(BR) min/max | 7.78–8.6 V - Breakdown occurs within this range at 10 mA test current; defines turn-on threshold under surge. |
| VC @ IPP | 12.0 V at 250 A - Clamped voltage seen by protected circuit during worst-case 10/1000 µs surge; determines stress on downstream ICs. |
| PPP | 3000 W - Peak pulse power handling at 10/1000 µs; correlates to IEC61000-4-5 Class 4 lightning immunity with 42 Ω source. |
| ID @ VWM | 200 µA max - Leakage current at rated standoff; low enough to avoid loading 7 V bias rails or battery-powered circuits. |
| TJ/TSTG | −55 to +150 °C - Operating and storage temperature range compatible with extended industrial and outdoor telecom environments. |
| RoHS | e3 suffix - Matte-tin termination, lead-free, compliant with EU RoHS Directive 2011/65/EU. |
Pinout & Package
MXDA3KP7.0AE3 uses a 2-pin SMD package (case outline per Page 6 of RF01243 Rev B): void-free UL94V-0 thermosetting epoxy body, tin-lead or matte-tin plating, polarity marked with dot indicating Pin 1 (cathode). Weight ≈5 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line (e.g., +VDC rail); conducts during overvoltage to shunt current to ground. |
| Pin 2 | Anode | Connected to system ground; completes low-impedance path for surge current during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables compliance with IEC61000-4-5 Class 4 (42 Ω source) and robust protection against inductive load switching surges. |
| 12.0 V clamping at 250 A | Limits voltage stress on 5 V or 3.3 V logic rails and power management ICs during full-rated surge events. |
| Sub-100 ps response time | Provides effective suppression of ESD (IEC61000-4-2) and EFT (IEC61000-4-4) transients before damage occurs. |
| UL94V-0 void-free epoxy case | Ensures flame resistance and mechanical integrity in high-vibration or high-humidity industrial enclosures. |
| MIL-PRF-19500 screening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and surge testing per military-grade standards. |
Applications
| Industrial Power Input Protection | Telecom DC Feeder Lines |
|---|---|
Use Scenario: 24 V DC input stage of programmable logic controller (PLC) exposed to motor drive switching noise and field wiring surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed between +24 V rail and chassis ground to clamp positive-going transients. Use Value: Limits voltage excursion to ≤12.0 V during 250 A surges, preventing latch-up or gate oxide damage in upstream DC/DC controllers and microcontrollers. | Use Scenario: −48 V DC power feed to remote radio unit (RRU) in cellular base station, subject to lightning-induced longitudinal surges. IC Role / Device Role / Timing Role: Cathode tied to −48 V rail, anode to ground; clamps negative transients relative to ground reference. Use Value: Withstands 3000 W surges per IEC61000-4-5 (42 Ω, Class 4), preserving integrity of PoE-like power delivery and analog monitoring circuitry. |
| Automotive Body Control Module (BCM) | Medical Equipment Power Entry |
Use Scenario: 12 V battery-supplied BCM subjected to load dump and alternator ripple per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Primary TVS on main power input, positioned ahead of LDO regulators and CAN transceivers. Use Value: Clamps to 12.0 V at 250 A, protecting 12 V tolerant ICs while surviving repeated 3000 W pulses without degradation. | Use Scenario: AC/DC adapter output stage feeding isolated patient-connected diagnostic equipment requiring low leakage and high surge margin. IC Role / Device Role / Timing Role: Final-stage TVS on secondary-side DC output, guarding against internal capacitor failure or external coupling events. Use Value: 200 µA max ID at 7.0 V ensures no measurable impact on precision analog references or isolated feedback loops. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A | 600 W PPP rating, 10.5 V VC @ 38.8 A IPP, DO-214AC package | Lower surge capacity; suitable only for IEC61000-4-5 Class 2 or lower-energy ESD/EFT. | Select SMAJ7.0A only where board space is constrained and surge threat level is limited to sub-1 kA. |
| SMCJ7.0A | 1500 W PPP rating, 12.0 V VC @ 125 A IPP, DO-214AB package | Half the peak power handling; requires derating for repeated surges or higher ambient temperatures. | Choose SMCJ7.0A when cost sensitivity outweighs need for full 3000 W immunity, but verify thermal margin in enclosure. |
Compared with SMAJ7.0A and SMCJ7.0A, MXDA3KP7.0AE3 delivers double the surge energy margin of SMCJ7.0A and five times that of SMAJ7.0A-enabling single-device compliance with IEC61000-4-5 Class 4 without parallel staging or thermal compromise.

FAQ
What is the clamping voltage of the MXDA3KP7.0AE3 at its rated peak pulse current?
The MXDA3KP7.0AE3 has a maximum clamping voltage (VC) of 12.0 V at 250 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value is measured per standard TVS test methods and ensures predictable voltage limiting during surge events. The MXDA3KP7.0AE3 maintains this clamping performance across its full operating temperature range when derated per Figure 3 of the datasheet.
Is the MXDA3KP7.0AE3 RoHS compliant?
Yes, the MXDA3KP7.0AE3 is RoHS compliant, indicated by the "e3" suffix in its part number. It features annealed matte-tin plating per MIL-STD-750 Method 2026 and meets EU Directive 2011/65/EU requirements. The device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits, and is suitable for environmentally regulated industrial and medical applications.
Can the MXDA3KP7.0AE3 be used for bidirectional transient suppression?
No, the MXDA3KP7.0AE3 is unidirectional only. Its part number lacks the "C" suffix (e.g., MDA3KP7.0CE3), which designates bidirectional construction. As a unidirectional TVS, it protects against positive transients on a line referenced to ground. For bidirectional protection-such as AC signal lines or floating buses-use the MDA3KP7.0CE3 variant instead.
What is the standoff voltage rating of the MXDA3KP7.0AE3, and how should it be selected?
The MXDA3KP7.0AE3 has a rated reverse standoff voltage (VWM) of 7.0 V, meaning it remains non-conductive up to this DC or peak AC voltage. To ensure reliable operation, VWM must be ≥ the maximum normal operating voltage of the protected line. For example, use MXDA3KP7.0AE3 on a nominal 5 V rail where peak excursions reach ≤7.0 V, but select MXDA3KP12AE3 for a 9 V supply.
Does the MXDA3KP7.0AE3 require a heatsink for standard operation?
No, the MXDA3KP7.0AE3 does not require an external heatsink under normal surge conditions because its 3000 W rating applies to short-duration 10/1000 µs pulses-not continuous power dissipation. However, thermal derating is required above 25 °C ambient, as shown in Figure 3 of the datasheet. PCB copper area and layout influence steady-state thermal performance, but no heatsink is specified for single-event surge handling.
