Product details
Overview
MDA3KP9.0AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 9.0 V standoff voltage (VWM), 10.0–11.1 V breakdown voltage (V(BR)), and 15.4 V maximum clamping voltage (VC) at 194.8 A peak pulse current (IPP). It provides secondary lightning protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in power supply input stages.
For engineers reviewing the MDA3KP9.0AE3 datasheet, MDA3KP9.0AE3 pinout, MDA3KP9.0AE3 application, or MDA3KP9.0AE3 equivalent, this device is selected for high-reliability DC rail protection where fast response (<100 ps), low clamping ratio (VC/VWM ≈ 1.71), RoHS-compliant packaging, and MIL-PRF-19500 upscreening capability are required.
Technical Context
The MDA3KP9.0AE3 operates as a unidirectional avalanche diode-based TVS array optimized for vertical mounting on PCBs. Its junction temperature range spans –55 °C to +150 °C, and it delivers 3000 W peak pulse power at 10/1000 μs waveform with <100 ps response time. Standby leakage is limited to 10 μA at 9.0 V VWM, ensuring minimal impact on system quiescent current.
It features tin-lead or matte-tin plating compliant with MIL-STD-750 Method 2026, void-free UL94V-0 epoxy encapsulation, and polarity defined by odd-numbered pins as cathodes. The device is rated for 260 °C solder temperature (10 s) and exhibits no moisture sensitivity (IPC/JEDEC J-STD-020B Level 1).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 10.0–11.1 V @ 1 mA - Ensures reliable avalanche initiation above operating rail, minimizing false triggering |
| VC @ IPP | 15.4 V @ 194.8 A - Limits downstream voltage stress during 10/1000 μs transients to safe levels |
| ID @ VWM | 10 μA - Negligible standby leakage for battery-backed or low-power systems |
| PPP | 3000 W @ 10/1000 μs - Handles high-energy surges common in industrial power inputs and telecom interfaces |
| TJ/TSTG | –55 to +150 °C - Supports operation in extended-temperature environments including automotive under-hood and industrial control cabinets |
Pinout & Package
The MDA3KP9.0AE3 uses a 3-pin SMC (DO-214AB) package with cathode-anode-cathode configuration. Pin 1 and Pin 3 are cathodes; Pin 2 is the anode. Polarity is marked by a dot on the package top adjacent to Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line (e.g., +12 V rail); conducts when transient exceeds V(BR) |
| Pin 2 | Anode | Common return path to ground or low-side reference; defines unidirectional conduction direction |
| Pin 3 | Cathode | Second protected line (e.g., auxiliary supply); enables dual-rail protection in single package |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse rating | Enables robust protection against IEC61000-4-5 Class 4 surges (2 Ω source) without derating at 25 °C |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A | 600 W PPP rating, same VWM and V(BR) range, SMA package (smaller thermal mass) | Limited to lower-energy transients; unsuitable for IEC61000-4-5 Class 4 (2 Ω) testing | Select MDA3KP9.0AE3 when 3000 W surge handling and industrial-grade reliability are mandatory |
| SMCJ9.0A | 1500 W PPP rating, identical SMC package footprint but lower clamping (14.4 V) and higher IPP (139 A) | Marginally meets IEC61000-4-5 Class 2 (2 Ω); not qualified for MIL-PRF-19500 screening | Choose MDA3KP9.0AE3 for aerospace/defense programs requiring traceable upscreening and full 3000 W compliance |
Compared with SMAJ9.0A and SMCJ9.0A, the MDA3KP9.0AE3 delivers double the pulse power handling of SMCJ9.0A and five times that of SMAJ9.0A, with verified MIL-PRF-19500 upscreening paths and tighter V(BR) distribution-critical for high-availability infrastructure where surge margin directly impacts field failure rates.

FAQ
What is the clamping voltage of MDA3KP9.0AE3 at its rated peak pulse current?
The MDA3KP9.0AE3 has a maximum clamping voltage (VC) of 15.4 V at its rated peak pulse current (IPP) of 194.8 A under 10/1000 μs waveform conditions. This value is measured per standard test methods and ensures predictable overvoltage limiting during surge events. The clamping ratio (VC/VWM = 1.71) reflects efficient energy diversion without excessive voltage overshoot. Designers use this parameter to verify downstream component voltage ratings remain within safe margins when MDA3KP9.0AE3 is deployed.
Is MDA3KP9.0AE3 RoHS-compliant and what does the 'e3' suffix indicate?
Yes, MDA3KP9.0AE3 is RoHS-compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide. The 'e3' designation specifies matte-tin plating compliant with JEDEC J-STD-020B Level 1 moisture sensitivity and RoHS Directive 2011/65/EU. This ensures compatibility with standard Pb-free reflow profiles while maintaining solderability and corrosion resistance. The 'e3' marking is laser-etched or molded into the package body and is traceable to manufacturing lot records for MDA3KP9.0AE3.
Can MDA3KP9.0AE3 be used for bidirectional transient protection?
No, MDA3KP9.0AE3 is a unidirectional TVS device, as indicated by the absence of the 'C' suffix in its part number. Bidirectional variants (e.g., MDA3KP9.0CE3) are separately specified with symmetrical breakdown characteristics. Using MDA3KP9.0AE3 in AC or bipolar signal paths would result in forward conduction during negative half-cycles, potentially causing malfunction or damage. For bidirectional protection, select the 'C' version or pair two unidirectional devices back-to-back-never substitute MDA3KP9.0AE3 in place of a bidirectional design.
What is the standoff voltage rating and how does it relate to system operating voltage?
The MDA3KP9.0AE3 has a rated working standoff voltage (VWM) of 9.0 V, meaning it remains non-conductive up to this DC or peak AC voltage across its terminals. System operating voltage must be ≤ VWM to prevent leakage or premature conduction; for a nominal 12 V rail, MDA3KP9.0AE3 is undersized-MDA3KP12A (12 V VWM) would be appropriate. Selecting VWM ≥ 1.1× maximum steady-state voltage ensures margin against ripple and tolerance drift while retaining effective clamping at V(BR) > VWM.
Does MDA3KP9.0AE3 require derating at elevated ambient temperatures?
Yes, MDA3KP9.0AE3 requires thermal derating above 25 °C ambient, as shown in Figure 3 of its datasheet. At 100 °C case temperature, its peak pulse power drops to ~60% of the 3000 W rating. Derating is necessary because junction temperature rise during surge events increases with ambient, risking thermal runaway if power dissipation exceeds safe limits. Designers must calculate worst-case power dissipation using thermal resistance data and apply the published derating curve to ensure MDA3KP9.0AE3 maintains full surge capability across the intended operating temperature range.
