Product details
Overview
MDA3KP10AE3 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 from −55 °C to +150 °C - used in industrial motor drives, telecom power supplies, and automotive ECUs.
For engineers reviewing the MDA3KP10AE3 datasheet, MDA3KP10AE3 pinout, MDA3KP10AE3 application, or MDA3KP10AE3 equivalent, key selection criteria include its 10 V VWM rating, 176.4 A IPP capability at 10/1000 µs, RoHS-compliant e3 termination, MIL-PRF-19500 upscreening eligibility, and unidirectional polarity with cathode-defined pin 1.
Technical Context
The MDA3KP10AE3 employs an avalanche diode structure optimized for sub-100 ps response time and low clamping ratio (VC/V(BR) ≈ 1.45). Its 3000 W peak pulse power rating is validated per IEC61000-4-5 (secondary lightning, 42 Ω source) and supports ESD/EFT immunity per IEC61000-4-2/4-4.
It is rated for 1000 µA standby current at VWM and undergoes full lot surge testing. The device uses void-free UL94V-0 epoxy packaging with tin-lead or matte-tin plating, and polarity is defined by a dot marking indicating cathode on odd-numbered pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 11.1–12.3 V @ 1 mA - ensures reliable avalanche initiation above operating rail |
| VC @ IPP | 17.0 V @ 176.4 A - limits downstream voltage stress during 10/1000 µs transients |
| PPP | 3000 W @ 10/1000 µs - sustains high-energy surges common in industrial switching and lightning-induced events |
| ID @ VWM | 5 µA - ultra-low leakage preserves efficiency in battery-backed or low-power monitoring circuits |
| TJ/TSTG | −55 °C to +150 °C - enables deployment in under-hood automotive, outdoor telecom, and high-temp industrial enclosures |
Pinout & Package
MDA3KP10AE3 is housed in a vertically mounted, transfer-molded plastic package (case outline per RF01243, Page 6) measuring 21.03–22.05 mm × 6.86–7.87 mm × 8.64–9.65 mm (L×W×H), with matte-tin or tin-lead terminations and RoHS-compliant e3 marking. Polarity is indicated by a dot on top of the package denoting pin 1 as cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; clamps positive transients to ground when referenced to anode |
| Pin 2 | Anode | Typically tied to system ground or low-impedance return path for unidirectional operation |
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 |
| 17.0 V clamping at 176.4 A | Keeps protected ICs (e.g., MCU I/O, gate drivers) below absolute maximum ratings during worst-case transients |
| MIL-PRF-19500 upscreening option | Supports aerospace and defense programs requiring wafer lot traceability, 3σ ID screening, and extended reliability validation |
| Level 1 moisture sensitivity | Eliminates dry-pack requirement and floor-life constraints - simplifies SMT assembly and inventory handling |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
Use Scenario: Protection of DC bus inputs against switching transients from IGBT commutation and regenerative braking. IC Role / Device Role / Timing Role: Unidirectional TVS placed between +BUS and GND to clamp positive spikes before they reach bulk capacitors or controller ICs. Use Value: Prevents premature failure of electrolytic capacitors and gate drivers by limiting transient voltage to ≤17.0 V at 176.4 A. | Use Scenario: Input-stage surge suppression on −48 V DC distribution boards in central office equipment. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing IEC61000-4-5 surges while maintaining low leakage (<5 µA) to avoid load regulation drift. Use Value: Maintains system uptime by surviving repeated 2 kV/42 Ω surges without parameter shift or thermal runaway. |
| Automotive Engine Control Units | Renewable Energy Inverters |
Use Scenario: Protection of 12 V sensor supply rails exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary clamping device on microcontroller power input, coordinated with upstream fuses and LC filters. Use Value: Withstands 150 °C junction temperature and passes AEC-Q101 stress tests when integrated into under-hood PCB layouts. | Use Scenario: DC-link overvoltage suppression in solar string inverters subjected to grid-switching transients. IC Role / Device Role / Timing Role: Parallel-connected TVS array across PV-side DC bus to divert fast-rising transients induced by contactor opening. Use Value: Delivers 3000 W dissipation without derating at 70 °C ambient - reduces need for thermal margin overhead in compact enclosures. |
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 - lower energy handling than MDA3KP10AE3 | Best suited for consumer-grade, low-surge environments; not rated for IEC61000-4-5 Class 4 | Select SMBJ10A only where surge threat level is limited to ESD/EFT or low-energy switching noise. |
| SMCJ10A | 1500 W PPP rating, 17.0 V VC @ 87.8 A IPP - half the pulse power of MDA3KP10AE3 | Valid for IEC61000-4-5 Class 2 (2 kV) but insufficient for Class 4 (4 kV) with 42 Ω source impedance | Choose SMCJ10A for cost-sensitive industrial controls where full 3000 W immunity is not required. |
Compared with SMBJ10A and SMCJ10A, the MDA3KP10AE3 provides double the pulse power capacity of SMCJ10A and five times that of SMBJ10A - enabling single-point protection in high-threat environments like factory automation and base station power entry without parallel staging.

FAQ
What is the clamping voltage of MDA3KP10AE3 at its rated peak pulse current?
The MDA3KP10AE3 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 measured per standard test methods and guarantees that downstream circuitry remains within safe voltage limits during high-energy transients. The MDA3KP10AE3 achieves this clamping performance while maintaining low leakage and high-temperature stability.
Is MDA3KP10AE3 RoHS compliant?
Yes, MDA3KP10AE3 is RoHS compliant, as indicated by the "e3" suffix in its part number. This denotes annealed matte-tin termination 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 industrial and telecom applications.
Does MDA3KP10AE3 support MIL-PRF-19500 upscreening?
Yes, MDA3KP10AE3 supports optional MIL-PRF-19500 upscreening per Microsemi's qualification program, including wafer lot traceability, 3σ screening on standby current (ID), and conformance inspections. While the base MDA3KP10AE3 is commercial-grade, upscreened units are available for aerospace and defense programs requiring enhanced reliability documentation and test data.
What is the polarity configuration of MDA3KP10AE3?
MDA3KP10AE3 is a unidirectional TVS device, with pin 1 designated as cathode and pin 2 as anode - confirmed by the absence of "C" in its part number and the polarity marking (dot on package top). This configuration allows it to clamp only positive-going transients relative to ground, making it ideal for DC rail protection where reverse voltage is not expected.
How does MDA3KP10AE3 compare to MDA3KP10CA?
The MDA3KP10AE3 is unidirectional, while MDA3KP10CA is bidirectional - differing in internal diode architecture and polarity behavior. MDA3KP10CA clamps both positive and negative transients, whereas MDA3KP10AE3 only clamps positive excursions. Their VWM, V(BR), and VC values are identical, but MDA3KP10AE3 offers lower capacitance and better DC blocking for single-polarity rails.
