Product details
Overview
MDA3KP30AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 30 V standoff voltage (VWM), 33.3–36.8 V breakdown voltage (V(BR)), and 48.4 V clamping voltage (VC) at 62 A peak pulse current. It delivers lightning surge protection per IEC61000-4-5 (Class 1–4, 42 Ω source), ESD immunity per IEC61000-4-2, and EFT suppression per IEC61000-4-4 in telecom power interfaces.
For engineers reviewing the MDA3KP30AE3 datasheet, MDA3KP30AE3 pinout, MDA3KP30AE3 application, or MDA3KP30AE3 equivalent, key selection criteria include its 30 V working voltage, sub-100 ps response time, RoHS-compliant e3 marking, 150 °C junction rating, and compatibility with high-reliability MIL-PRF-19500 upscreening options.
Technical Context
This TVS array uses silicon avalanche diode technology to clamp transient overvoltages before they damage downstream circuitry. Its unidirectional polarity enables DC-biased protection paths, and its 10/1000 μs waveform-rated 3000 W peak pulse power supports robust secondary lightning immunity.
The device operates across –55 °C to +150 °C, features <2 μA standby current at 30 V, and maintains clamping performance under thermal derating per Figure 3. Its void-free epoxy package meets UL94V-0 flammability and IPC/JEDEC J-STD-020B Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30 V - Maximum continuous DC or peak AC operating voltage before clamping initiates |
| V(BR) min/max | 33.3–36.8 V @ 1 mA - Ensures reliable turn-on above normal operating margin without false triggering |
| VC @ IPP | 48.4 V @ 62 A - Limits voltage seen by protected ICs during worst-case 10/1000 μs surges |
| PPP | 3000 W @ 10/1000 μs - Sustains high-energy transients typical of telecom line surges and inductive switching |
| TJ range | –55 to +150 °C - Supports operation in industrial and automotive under-hood environments |
| Response time | <100 ps - Clamps ESD events faster than most interface ICs can be damaged |
| Moisture level | IPC/JEDEC J-STD-020B Level 1 - No dry pack or bake-out required prior to reflow |
Pinout & Package
MDA3KP30AE3 is housed in a surface-mount, void-free thermosetting epoxy package (UL94V-0) weighing ~5 g. Pin 1 is marked by a dot on the top surface; odd-numbered pins are cathodes per device polarity convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (TVS1) | Connected to protected line; clamps positive transients to ground when forward-biased relative to anode |
| Pin 2 | Anode (TVS1) | Typically tied to system ground; completes clamping path for unidirectional operation |
| Pin 3 | Cathode (TVS2) | Second independent clamping channel; enables dual-line or differential protection |
| Pin 4 | Anode (TVS2) | Shared or isolated ground return depending on layout; supports independent or common-ground configuration |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables single-device protection against IEC61000-4-5 Class 4 surges (4 kV, 42 Ω source) without cascaded stages |
| RoHS-compliant e3 marking | Confirms lead-free matte-tin plating and full compliance with Directive 2011/65/EU Annex II |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and conformance inspection |
| Sub-100 ps response | Prevents latch-up or gate oxide rupture in fast-edge logic and high-speed interface ICs during ESD events |
| Level 1 moisture sensitivity | Eliminates pre-reflow baking, reducing assembly cost and avoiding thermal stress on sensitive substrates |
Applications
| Telecom Line Interface Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting RS-485/RS-422 transceivers on outdoor telecom node backplanes exposed to induced lightning surges. IC Role / Device Role / Timing Role: Primary clamping element placed between data line and chassis ground, absorbing 4 kV/42 Ω surges before transceiver input pins. Use Value: Maintains signal integrity by limiting line voltage to ≤48.4 V during 10/1000 μs transients, preventing permanent damage to ±15 V tolerant receivers. | Use Scenario: Safeguarding analog input channels of programmable logic controllers in factory-floor motor control cabinets. IC Role / Device Role / Timing Role: Unidirectional TVS on 24 V DC sensor supply lines, shunting inductive kickback from solenoid drivers.

IC Role / Device Role / Timing Role: First-stage transient suppressor ahead of bulk capacitor and PFC controller, diverting energy before it reaches primary-side MOSFETs. Use Value: Delivers 62 A peak pulse current handling at 30 V standoff, enabling compact design versus multi-stage MOV+TVS solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | 600 W PPP rating, SMA package, 48.4 V VC @ 10.3 A IPP | Limited to lower-energy surges; insufficient for IEC61000-4-5 Class 3/4 | Select MDA3KP30AE3 where 3000 W surge handling and MIL-qualified reliability are required. |
| SMCJ30A | 1500 W PPP rating, SMC package, 48.4 V VC @ 31 A IPP | Half the peak power capacity; requires parallel devices for Class 4 compliance | Choose MDA3KP30AE3 for single-device Class 4 lightning protection without layout redesign. |
Compared with SMAJ30A and SMCJ30A, MDA3KP30AE3 provides double the surge energy handling of SMCJ30A and five times that of SMAJ30A in the same functional voltage class-enabling simplified, high-confidence protection architecture for mission-critical infrastructure.

FAQ
What is the clamping voltage of MDA3KP30AE3 at its rated peak pulse current?
The MDA3KP30AE3 has a maximum clamping voltage (VC) of 48.4 V at 62 A peak pulse current (IPP), measured under standard 10/1000 μs waveform conditions. This value ensures protected circuitry remains below critical overvoltage thresholds during high-energy transients. The MDA3KP30AE3 achieves this clamping performance while maintaining low leakage (<2 μA at 30 V) in normal operation.
Is MDA3KP30AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MDA3KP30AE3 is RoHS compliant. The 'e3' suffix explicitly denotes lead-free matte-tin terminal plating per Directive 2011/65/EU Annex II, confirmed in Microsemi's RF01243 Rev B datasheet. This marking replaces legacy tin-lead finishes and ensures compatibility with modern Pb-free reflow profiles. The MDA3KP30AE3 also meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity requirements.
Can MDA3KP30AE3 be used for bidirectional transient suppression?
No, MDA3KP30AE3 is unidirectional. Its part number lacks the 'C' suffix (e.g., MDA3KP30CE3), which designates bidirectional construction in the MDA3KP family. The MDA3KP30AE3 clamps only positive-going transients relative to its anode connection and must be oriented with cathode toward the protected line. For AC or differential line protection, a bidirectional variant or back-to-back configuration is required.
What is the maximum operating temperature range for MDA3KP30AE3?
The MDA3KP30AE3 is rated for junction and storage temperatures from –55 °C to +150 °C. This extended range supports deployment in harsh environments such as automotive under-hood modules, industrial motor drives, and outdoor telecom enclosures. Derating curves in Figure 3 of the datasheet define allowable pulse power reduction above 25 °C ambient, ensuring safe operation across the full thermal envelope.
Does MDA3KP30AE3 meet IEC61000-4-5 Class 4 lightning surge immunity?
Yes, MDA3KP30AE3 meets IEC61000-4-5 Class 4 (4 kV) secondary lightning surge immunity when tested with a 42 Ω source impedance, as confirmed in the Applications/Benefits section of RF01243 Rev B. Its 3000 W peak pulse power rating and 48.4 V clamping voltage enable direct compliance without additional staging. The MDA3KP30AE3 is validated for Class 1–4 under 42 Ω and Class 1–3 under 12 Ω source impedances.
