Product details
Overview
MADA3KP11AE3 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 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 - deployed in industrial motor drives, telecom power supplies, and automotive ECUs.
For engineers reviewing the MADA3KP11AE3 datasheet, MADA3KP11AE3 pinout, MADA3KP11AE3 application, or MADA3KP11AE3 equivalent, key selection criteria include its 10/1000 µs surge rating, RoHS-compliant matte-tin plating, UL94V-0 epoxy package, and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and secondary lightning protection.
Technical Context
The MADA3KP11AE3 is a single-channel unidirectional TVS diode optimized for fast clamping of high-energy transients. Its <100 ps response time enables suppression of ESD events per IEC61000-4-2 and switching-induced surges in DC power distribution networks.
It delivers 3000 W peak pulse power at 10/1000 µs waveform with 18.2 V clamping voltage at 164.8 A IPP, and maintains <5 µA standby current at 11 V VWM - ensuring minimal leakage in always-on systems while preserving system-level immunity to 42 Ω, 12 Ω, and 2 Ω source impedance lightning surges per IEC61000-4-5 Class 1–4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11 V - Maximum continuous operating voltage before clamping begins; matches 12 V nominal rail systems with margin. |
| V(BR) min/max | 12.2–13.5 V @ 1 mA - Confirmed breakdown threshold ensures predictable turn-on during overvoltage events. |
| VC @ IPP | 18.2 V @ 164.8 A - Clamping voltage limits downstream IC stress during 3000 W transients. |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy surges without failure in industrial power interfaces. |
| ID @ VWM | 5 µA max - Ultra-low leakage preserves battery life and avoids false triggering in low-power circuits. |
| TJ range | –55 °C to +150 °C - Supports under-hood automotive and high-temp industrial environments. |
| RoHS | e3 marking - Compliant matte-tin termination compatible with lead-free reflow profiles. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; conducts surge current to ground when V > V(BR). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | 600 W PPP rating, SMA package, 18.2 V VC @ 32.4 A IPP - lower surge capacity and smaller thermal mass. | Targeted at consumer-grade PCBs with lower surge exposure; not qualified for MIL-PRF-19500 screening. | Select SMAJ11A only for cost-sensitive, non-mission-critical designs where 3000 W surge capability is unnecessary. |
| SMCJ11A | 1500 W PPP rating, SMC package, 18.2 V VC @ 83.3 A IPP - half the peak power and 50% lower IPP than MADA3KP11AE3. | Suitable for mid-tier industrial equipment but lacks Class 4 lightning immunity per IEC61000-4-5 with 42 Ω source. | Choose SMCJ11A when board space constraints prevent use of the larger MADA3KP11AE3 D2PAK footprint. |
Compared with SMAJ11A and SMCJ11A, the MADA3KP11AE3 delivers double the surge energy handling of SMCJ11A and five times that of SMAJ11A - enabling single-device protection for high-reliability 12 V systems exposed to automotive load dump and industrial lightning surges.

FAQ
What is the clamping voltage of the MADA3KP11AE3 at its rated peak pulse current?
The MADA3KP11AE3 has a maximum clamping voltage (VC) of 18.2 V at its 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 3000 W transient event. The MADA3KP11AE3 maintains this clamping performance across its full operating temperature range.
Is the MADA3KP11AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, the MADA3KP11AE3 is RoHS compliant, as confirmed by the 'e3' suffix in its part number. Per Microsemi's nomenclature guide, 'e3' denotes matte-tin plating meeting RoHS Directive 2011/65/EU requirements and compatibility with lead-free reflow soldering processes. The MADA3KP11AE3 requires no special handling or dry packing due to its IPC/JEDEC J-STD-020B Level 1 moisture sensitivity rating.
Does the MADA3KP11AE3 support MIL-PRF-19500 screening and what does that entail?
Yes, the MADA3KP11AE3 supports optional MIL-PRF-19500 upscreening, including wafer lot traceability, 3σ lot norm screening on standby current (ID), and conformance inspections per military reliability standards. This screening is documented in Micronote 129 and enables use in aerospace, defense, and high-integrity industrial applications where process control and long-term reliability validation are mandatory - beyond standard commercial-grade qualification of the base MADA3KP11AE3.
How does the MADA3KP11AE3 perform under IEC61000-4-5 secondary lightning test conditions?
The MADA3KP11AE3 is rated for secondary lightning protection per IEC61000-4-5 across multiple source impedances: Class 1–4 with 42 Ω, Class 1–3 with 12 Ω, and Class 2–4 with 2 Ω source impedance. Its 3000 W peak pulse power and 18.2 V clamping voltage ensure compliance without external series impedance - making it suitable for direct placement on 12 V rails in telecom and automotive ECUs subjected to coupled lightning surges.
What is the thermal derating behavior of the MADA3KP11AE3 above 25 °C ambient?
The MADA3KP11AE3 follows a linear thermal derating curve beginning at +25 °C, reducing peak pulse power capability proportionally as junction temperature rises - per Figure 3 in the official datasheet. At +125 °C, its PPP drops to approximately 50% of the 25 °C rating (i.e., ~1500 W), while still maintaining full clamping voltage specification. Derating must be applied in high-temperature enclosures or high-duty-cycle surge environments to ensure MADA3KP11AE3 reliability.
