Product details
Overview
MXDA3KP26AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 26 V standoff voltage (VWM), 28.9–31.9 V breakdown range (V(BR)), and 42.1 V maximum clamping voltage (VC) at 71.2 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 industrial power supplies.
For engineers reviewing the MXDA3KP26AE3 datasheet, MXDA3KP26AE3 pinout, MXDA3KP26AE3 application, or MXDA3KP26AE3 equivalent, key selection criteria include its 26 V working standoff, sub-100 ps response time, RoHS-compliant e3 marking, MIL-PRF-19500 upscreening capability, and 5 g molded epoxy package suitable for high-reliability board-level surge protection.
Technical Context
The MXDA3KP26AE3 operates as a unidirectional avalanche diode-based TVS array optimized for fast transient suppression in DC power rails and signal lines. Its clamping behavior is defined by a 42.1 V VC at 71.2 A IPP under 10/1000 μs waveform, with <100 ps response time from 0 V to V(BR) min.
It meets IEC61000-4-5 secondary lightning immunity with 42 Ω source impedance across Classes 1–4, and supports temperature derating per Figure 3 - retaining ≥80% of 3000 W rating up to +100 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 26 V - maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 28.9–31.9 V @ 1 mA - ensures reliable avalanche initiation above operating voltage with 5% tolerance |
| VC @ IPP | 42.1 V @ 71.2 A - limits downstream voltage stress during worst-case 10/1000 μs surge |
| PPP | 3000 W @ 10/1000 μs - delivers robust single-pulse energy handling for industrial surge events |
| ID @ VWM | 2 μA max - negligible leakage current preserves efficiency in low-power standby circuits |
| TJ/TSTG | −55 to +150 °C - enables deployment in extended-temperature automotive and aerospace environments |
Pinout & Package
MXDA3KP26AE3 uses a 2-pin surface-mount DO-214AB (SMC) package with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity marked by dot indicating Pin 1 (cathode). Weight ≈5 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; conducts during overvoltage to shunt current to ground |
| Pin 2 | Anode | Connected to system ground or return path; completes clamping circuit during transient |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables single-device protection against IEC61000-4-5 Level 4 surges (4 kV, 42 Ω) without cascading devices |
| Unidirectional construction | Prevents reverse-bias leakage in DC-coupled power rails while maintaining fast forward clamping |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and conformance inspection |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life constraints for automated SMT assembly |
Applications
| Industrial Power Supply Protection | Telecom Line Interface |
|---|---|
Use Scenario: 24 V DC input rail in programmable logic controllers exposed to inductive load switching and nearby lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS array clamping transients before they reach DC-DC converters and microcontrollers. Use Value: Limits voltage excursion to ≤42.1 V during 71.2 A surges, preventing latch-up or gate oxide damage in downstream ICs. | Use Scenario: T1/E1 interface cards in central office equipment subject to induced RF and EFT bursts per IEC61000-4-4. IC Role / Device Role / Timing Role: Primary surge suppression stage on tip/ring lines prior to isolation transformers and line drivers. Use Value: Sub-100 ps response ensures clamping occurs before EFT edge rates (<5 ns) propagate into sensitive analog front-ends. |
| Automotive Body Control Module | Renewable Energy Inverter DC Link |
Use Scenario: 12 V battery-supplied BCM modules enduring load dump and ISO 7637-2 pulses in harsh vehicle environments. IC Role / Device Role / Timing Role: Standoff-rated TVS placed directly at connector entry point to absorb high-energy transients. Use Value: 3000 W PPP rating sustains multiple 12 V load-dump events without degradation, verified per surge testing. | Use Scenario: DC bus protection in solar string inverters where PV array transients couple into 300–1000 V DC links. IC Role / Device Role / Timing Role: Secondary clamping device parallel to MOVs, providing precise voltage limiting and faster response. Use Value: 26 V VWM allows use in auxiliary control supply rails, while 42.1 V VC protects gate drivers and sensing ICs from overshoot. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ26A | 600 W PPP rating, same VWM and VC, DO-214AA package | Limited to lower-energy surges (IEC61000-4-5 Class 2 only) | Select when cost-sensitive designs tolerate reduced surge margin and smaller footprint |
| SMCJ26A | 1500 W PPP, identical DO-214AB package, same pinout and VWM | Insufficient for Class 4 lightning per 42 Ω source impedance | Choose for mid-tier industrial applications where 3000 W is not mandated |
Compared with SMBJ26A and SMCJ26A, MXDA3KP26AE3 delivers double the pulse power of SMCJ26A and five times that of SMBJ26A - enabling single-device compliance with IEC61000-4-5 Class 4 in high-impedance networks without parallel staging.

FAQ
What is the clamping voltage of the MXDA3KP26AE3 at its rated peak pulse current?
The MXDA3KP26AE3 has a maximum clamping voltage (VC) of 42.1 V at its rated peak pulse current (IPP) of 71.2 A under 10/1000 μs waveform conditions. This value is measured per standard test methods and guarantees the upper limit of voltage seen by downstream circuitry during a full-rated surge event. The MXDA3KP26AE3 maintains this clamping performance across its specified junction temperature range.
Is the MXDA3KP26AE3 RoHS compliant?
Yes, the MXDA3KP26AE3 is RoHS compliant, as indicated by the "e3" suffix in its part number. This denotes annealed matte-tin terminal plating meeting 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 end equipment.
Does the MXDA3KP26AE3 support MIL-PRF-19500 screening?
Yes, the MXDA3KP26AE3 supports optional MIL-PRF-19500 upscreening with conformance inspections including wafer lot traceability, 3σ screening on standby current (ID), and extended environmental testing. Screening is performed per Micronote 129 and requires explicit ordering with appropriate screening codes - the base MXDA3KP26AE3 is not screened unless specified.
What is the thermal derating behavior of the MXDA3KP26AE3 above 25 °C?
The MXDA3KP26AE3 follows a linear derating curve beginning at +25 °C, retaining approximately 80% of its 3000 W peak pulse power rating at +100 °C junction temperature, as shown in Figure 3 of the official datasheet. Derating continues to zero at +150 °C, ensuring predictable performance across its full −55 to +150 °C operating range. Thermal design must account for PCB copper area and ambient airflow.
How does the MXDA3KP26AE3 differ from bidirectional variants like MXDA3KP26CE3?
The MXDA3KP26AE3 is unidirectional, conducting only during positive transients relative to its cathode, whereas MXDA3KP26CE3 is bidirectional and clamps both polarities. This makes MXDA3KP26AE3 ideal for DC power rails with defined polarity, offering lower leakage and tighter V(BR) tolerance. MXDA3KP26CE3 suits AC-coupled or floating signal lines where polarity reversal may occur.
