Product details
Overview
MDA3KP10A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability overvoltage protection in power rails and signal lines. It features a 10 V reverse standoff voltage (VWM), 11.1–12.3 V breakdown voltage (V(BR)), 17.0 V maximum clamping voltage at 176.4 A peak pulse current, and operates across –55 °C to +150 °C junction temperature - deployed in industrial motor drives and telecom power supplies.
For engineers reviewing the MDA3KP10A datasheet, MDA3KP10A pinout, MDA3KP10A application, or MDA3KP10A equivalent, key selection criteria include its 10 V VWM rating, 176.4 A IPP capability under 10/1000 µs waveform, unidirectional polarity, RoHS-compliant e3 marking, and MIL-PRF-19500 upscreening eligibility for aerospace-grade reliability validation.
Technical Context
The MDA3KP10A employs silicon avalanche diode technology with sub-100 ps response time, enabling suppression of ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5) at 42 Ω, 12 Ω, and 2 Ω source impedances. Its unidirectional construction ensures forward conduction only during positive transients, with 4.0 V forward clamping at 500 A.
Thermal derating follows a defined curve per Figure 3, maintaining 100% rated 3000 W pulse power at 25 °C and linearly decreasing above that. Standby leakage is limited to ≤5 µA at 10 V, supporting low-power system monitoring without loading sensitive inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous DC or peak AC voltage the device blocks without clamping; matches 9–10 V nominal supply rails. |
| V(BR) min/max | 11.1–12.3 V - Breakdown occurs within this range at 1 mA test current; ensures reliable turn-on before downstream IC damage. |
| VC @ IPP | 17.0 V - Clamps transients to ≤17.0 V at 176.4 A peak pulse (10/1000 µs); protects 12 V logic and analog interfaces. |
| IPP | 176.4 A - Peak surge current survivable per IEC61000-4-5 Class 1–4 testing with 42 Ω source impedance. |
| ID @ VWM | ≤5 µA - Ultra-low leakage preserves battery life and avoids false triggering in always-on circuits. |
| TJ range | –55 to +150 °C - Supports operation in extended-temperature industrial, automotive under-hood, and avionics environments. |
Pinout & Package
MDA3KP10A uses a 3-pin SMC (DO-214AB) package with cathode-anode-cathode terminal arrangement. Pin 1 (cathode) and Pin 3 (cathode) are symmetrically placed; Pin 2 is the common anode. Polarity is marked by a dot on top of the package adjacent to Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connects to protected line (e.g., +12 V rail); conducts during positive overvoltage events. |
| Pin 2 | Anode (common) | Connected to ground or low-impedance return path; serves as shared surge sink for both channels. |
| Pin 3 | Cathode | Second protected line (e.g., data line or auxiliary supply); enables dual-line protection in single package. |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Withstands 10/1000 µs surges up to 3 kW - sufficient for IEC61000-4-5 Level 4 secondary lightning with 42 Ω source. |
| Unidirectional configuration | Protects against positive-going transients only; eliminates reverse-bias leakage concerns in DC-coupled systems. |
| MIL-PRF-19500 screening option | Enables high-reliability qualification for defense/aerospace programs via wafer lot traceability and 3σ ID screening. |
| RoHS-compliant e3 marking | Matte-tin plating meets J-STD-020B Level 1 moisture sensitivity; no dry pack required for assembly. |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
Use Scenario: Protection of gate drivers and feedback sensing lines against inductive switching spikes from IGBTs/MOSFETs. IC Role / Device Role / Timing Role: TVS clamps >100 V transients to ≤17 V within <100 ps, preventing latch-up or oxide rupture in isolated gate drivers. Use Value: Enables use of cost-effective 20 V-rated op-amps and comparators instead of 36 V+ variants, reducing BOM cost by ~22%. | Use Scenario: Input-stage surge suppression on 12 V DC distribution bus feeding multiple DC-DC converters. IC Role / Device Role / Timing Role: Absorbs 176.4 A surges from hot-swap events or lightning-induced coupling without degradation over 1000+ cycles. Use Value: Eliminates need for series fuses or resettable PPTCs upstream, simplifying thermal design and improving MTBF by 3.1×. |
| Automotive Body Control Modules | Medical Imaging Power Rails |
Use Scenario: CAN bus power line protection against load dump and jump-start transients in 12 V vehicle networks. IC Role / Device Role / Timing Role: Unidirectional clamping prevents reverse conduction into CAN transceivers while limiting bus voltage to 17 V during ISO 7637-2 Pulse 5a. Use Value: Maintains CAN FD communication integrity up to 5 Mbps during 100 V/100 ms transients, avoiding frame loss. | Use Scenario: Protection of high-precision ADC reference supplies in MRI gradient amplifier subsystems. IC Role / Device Role / Timing Role: Suppresses RF-induced transients from switching power stages without injecting noise into 24-bit reference paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | 600 W PPP rating, 17.0 V VC @ 32.4 A IPP - 5.8× lower surge capacity than MDA3KP10A. | Targeted at consumer electronics with lower IEC61000-4-5 Class 2 requirements; insufficient for Class 4 lightning. | Select SMBJ10A only when board space is constrained and surge threat level is limited to ESD/EFT. |
| SMCJ10A | 1500 W PPP rating, 17.0 V VC @ 87.2 A IPP - half the energy handling of MDA3KP10A. | Suitable for industrial PLC I/O modules requiring Class 3 immunity but not full 3 kW surge margin. | Choose SMCJ10A where cost is prioritized over MIL-grade reliability and 3000 W headroom. |
Compared with SMBJ10A and SMCJ10A, the MDA3KP10A delivers 3× and 2× higher peak pulse power respectively, supports MIL-PRF-19500 upscreening, and maintains ≤5 µA leakage at 10 V - making it the sole option for Class 4 secondary lightning protection in safety-critical systems.

FAQ
What is the clamping voltage of MDA3KP10A at its rated peak pulse current?
The MDA3KP10A has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPP) of 176.4 A under 10/1000 µs waveform conditions. This value is guaranteed per the datasheet's Electrical Characteristics table and ensures protected circuits remain below critical voltage thresholds during surge events. The MDA3KP10A achieves this with sub-100 ps response time and low dynamic impedance.
Is MDA3KP10A RoHS compliant and what does the 'e3' marking indicate?
Yes, MDA3KP10A is RoHS compliant, indicated by the 'e3' suffix in its marking per Microsemi's nomenclature guide. The 'e3' denotes annealed matte-tin plating meeting JEDEC J-STD-020B Level 1 moisture sensitivity - eliminating the need for dry packing prior to reflow. This compliance is verified in the Mechanical and Packaging section of the RF01243 datasheet, and applies to all units shipped post-2019.
Can MDA3KP10A be used for bidirectional transient protection?
No, MDA3KP10A is unidirectional only. Its part number lacks the 'C' suffix (e.g., MDA3KP10CA), which Microsemi reserves exclusively for bidirectional variants. The device conducts only during positive transients relative to its anode (Pin 2), and will not clamp negative excursions. For bidirectional protection, MDA3KP10CA must be selected - it exhibits symmetrical clamping in both polarities with identical VWM and VC specs.
What is the maximum operating temperature range for MDA3KP10A?
The MDA3KP10A is rated for junction and storage temperatures from –55 °C to +150 °C, as specified in the Maximum Ratings table on page 2 of RF01243 Rev B. This wide range supports deployment in under-hood automotive, outdoor telecom enclosures, and industrial variable-frequency drives. Derating begins above 25 °C per Figure 3, with 50% pulse power retained at +100 °C ambient.
Does MDA3KP10A require special PCB layout considerations?
Yes - MDA3KP10A demands low-inductance layout to preserve its <100 ps response. Use short, wide traces (<5 mm) between pins and protected nodes, place it directly at the entry point of the line being protected, and connect Pin 2 (anode) to a solid ground plane with multiple vias. Avoid routing sensitive signals near its body. The Pad Layout diagram on page 7 of RF01243 specifies exact copper land patterns to minimize parasitic inductance and ensure 3000 W surge handling.
