Product details
Overview
MDA3KP11AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection. It features a 11 V reverse standoff voltage (VWM), 12.2–13.5 V breakdown voltage (V(BR)), 18.2 V maximum clamping voltage at 164.8 A peak pulse current, and operates across –55 °C to +150 °C junction temperature. It is used in telecom power interfaces and industrial I/O protection circuits.
For engineers reviewing the MDA3KP11AE3 datasheet, MDA3KP11AE3 pinout, MDA3KP11AE3 application, or MDA3KP11AE3 equivalent, key selection criteria include clamping performance at 10/1000 µs surge, standoff voltage margin relative to system DC rail, RoHS-compliant matte-tin termination, and MIL-PRF-19500 upscreening eligibility for aerospace-grade deployments.
Technical Context
The MDA3KP11AE3 is a single-channel unidirectional TVS diode optimized for fast transient suppression with <100 ps response time from 0 V to V(BR) min. Its 3000 W peak pulse power rating is validated per 10/1000 µs waveform, and it meets IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and IEC61000-4-5 (secondary lightning) with 42 Ω, 12 Ω, and 2 Ω source impedances.
It uses void-free UL94V-0 thermosetting epoxy packaging with tin-lead or annealed matte-tin plating, supports 260 °C soldering per MIL-STD-750 Method 2026, and maintains ≤5 µA standby current at 11 V VWM. Polarity is defined by dot marking: Pin 1 is cathode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 12.2–13.5 V @ 1 mA - Ensures reliable avalanche turn-on before downstream IC damage thresholds |
| VC @ IPP | 18.2 V @ 164.8 A - Clamping level that limits transient voltage seen by protected circuitry |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy surges common in industrial power line transients |
| TJ range | –55 °C to +150 °C - Enables deployment in under-hood automotive or outdoor telecom enclosures |
| ID @ VWM | 5 µA max - Low leakage preserves battery life and avoids false triggering in low-power sensing nodes |
| Moisture Level | IPC/JEDEC J-STD-020B Level 1 - No dry pack required; simplifies SMT handling and storage |
Pinout & Package
MDA3KP11AE3 uses a 2-pin surface-mount package with void-free UL94V-0 epoxy body and matte-tin terminations. Pin 1 (cathode) is marked by a dot on top of the package; polarity follows standard unidirectional TVS convention.
| 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 reference; completes current path during clamping event |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A | 600 W PPP rating, 17.0 V VC @ 33.3 A, DO-214AA package | Limited to lower-energy transients; unsuitable for IEC61000-4-5 Class 3/4 or 3000 W surge events | Select only when system surge energy is confirmed ≤600 W and PCB space constraints prohibit larger MDA footprint |
| SMCJ11A | 1500 W PPP rating, 18.2 V VC @ 82.5 A, DO-214AB package | Half the peak pulse power of MDA3KP11AE3; requires derating above 85 °C ambient | Use where cost sensitivity outweighs need for full 3000 W headroom and MIL-PRF-19500 screening is not required |
Compared with SMBJ11A and SMCJ11A, the MDA3KP11AE3 delivers double the surge energy handling of SMCJ11A and five times that of SMBJ11A, supports higher temperature operation (150 °C vs. 125 °C), and offers optional high-reliability screening-making it suitable for mission-critical infrastructure where transient robustness and long-term stability are non-negotiable.

FAQ
What is the clamping voltage of MDA3KP11AE3 at its rated peak pulse current?
The MDA3KP11AE3 has a maximum clamping voltage (VC) of 18.2 V at its rated peak pulse current (IPP) of 164.8 A under 10/1000 µs waveform conditions. This value is guaranteed per the manufacturer's electrical characteristics table and defines the upper voltage limit imposed on protected circuitry during a full-rated surge event. The MDA3KP11AE3 achieves this clamping performance while maintaining low leakage and high thermal stability across its full operating temperature range.
Is MDA3KP11AE3 RoHS compliant?
Yes, MDA3KP11AE3 is RoHS compliant, indicated by the "e3" suffix in its part number. It uses annealed matte-tin plating on terminations and complies with Directive 2011/65/EU. The device contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and its UL94V-0 epoxy package meets halogen-free requirements per IEC 61249-2-21.
Can MDA3KP11AE3 be used for bidirectional transient protection?
No, MDA3KP11AE3 is unidirectional. Its part number lacks the "C" suffix (e.g., MDA3KP11CE3), which designates bidirectional construction. It conducts only during positive transients applied to Pin 1 (cathode) relative to Pin 2 (anode). For bidirectional protection, select MDA3KP11CE3 or verify polarity alignment in the target circuit before substituting MDA3KP11AE3.
What is the maximum operating temperature for MDA3KP11AE3?
The MDA3KP11AE3 has a junction and storage temperature range of –55 °C to +150 °C. Its thermal design allows continuous operation at +150 °C ambient when mounted on appropriate copper area and airflow conditions. Derating of peak pulse power begins above 25 °C per Figure 3 in the datasheet, with 50% power capability retained at +100 °C case temperature.
Does MDA3KP11AE3 require moisture-sensitive level (MSL) handling?
No, MDA3KP11AE3 is rated IPC/JEDEC J-STD-020B Level 1, meaning it has unlimited floor life and does not require dry pack storage or baking prior to reflow. Its void-free epoxy encapsulation provides inherent moisture resistance, eliminating MSL-related handling steps and reducing manufacturing complexity for high-volume SMT assembly.
