Product details
Overview
MADA3KP11A 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. It protects against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5) in telecom power supplies.
For engineers reviewing the MADA3KP11A datasheet, MADA3KP11A pinout, MADA3KP11A application, or MADA3KP11A equivalent, this page delivers verified electrical parameters, package dimensions, IEC-compliant surge capability, polarity marking convention, and direct alternatives for industrial power rail protection design.
Technical Context
The MADA3KP11A is a single-channel unidirectional TVS diode optimized for fast clamping of high-energy transients with <100 ps response time. Its 3000 W peak pulse power rating is specified at 10/1000 µs waveform, and it maintains stable clamping performance up to 164.8 A IPP while limiting voltage to ≤18.2 V.
It uses a void-free thermosetting epoxy package rated UL94V-0, with tin-lead or matte-tin terminations compliant with MIL-STD-750 Method 2026. Polarity is defined by a dot marking indicating Pin 1 as cathode, consistent with unidirectional construction per part nomenclature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11 V - Maximum continuous DC or RMS operating voltage before conduction begins |
| V(BR) min/max | 12.2–13.5 V @ 1 mA - Ensures reliable turn-on above system nominal voltage with margin |
| VC @ IPP | 18.2 V @ 164.8 A - Clamped voltage during worst-case 10/1000 µs surge, protecting downstream ICs |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy lightning-induced transients without failure |
| ID @ VWM | 5 µA - Ultra-low leakage preserves efficiency in battery-backed or low-power circuits |
| TJ/TSTG | –55 °C to +150 °C - Enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom |
Pinout & Package
MDA3KP11A is housed in a surface-mount, 2-pin DO-214AB (SMC) package with cathode marked by a dot on the body. Pin 1 is cathode; Pin 2 is anode. The package meets UL94V-0 flammability rating and supports reflow soldering up to 260 °C for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line (e.g., +12 V rail); clamps to ground when transient exceeds V(BR) |
| Pin 2 | Anode | Typically tied to system ground; completes conduction path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Withstands IEC61000-4-5 Class 4 surges (42 Ω source) without degradation |
| 18.2 V clamping at 164.8 A | Keeps protected ICs (e.g., PMICs, microcontrollers) below absolute maximum ratings during surge |
| 5 µA standby current @ 11 V | Minimizes quiescent power loss in always-on systems like remote sensors or backup power monitors |
| –55 °C to +150 °C operation | Validated for use in harsh environments including industrial PLCs and automotive junction boxes |
Applications
| Telecom Power Input Protection | Industrial Motor Drive DC Bus |
|---|---|

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; same VWM and V(BR) range; DO-214AA package | Lower surge capacity suits consumer-grade equipment with reduced IEC61000-4-5 Class 2 requirements | Select SMBJ11A where cost sensitivity outweighs need for Class 4 lightning immunity |
| 1.5KE11A | Through-hole TO-218 package; 1500 W PPP; higher thermal mass but larger footprint | Preferred in legacy industrial designs requiring manual assembly or higher sustained surge duty cycles | Choose 1.5KE11A only if board layout allows axial/TO-218 placement and thermal relief is available |
Compared with SMBJ11A and 1.5KE11A, MADA3KP11A delivers 2× and 2× higher peak pulse power respectively in a surface-mount package, enabling compact, high-immunity protection for next-generation telecom and automotive electronics without compromising reliability screening.

FAQ
What is the clamping voltage of MADA3KP11A at its rated peak pulse current?
MADA3KP11A 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 across the full operating temperature range and ensures downstream circuitry remains within safe voltage limits during surge events. The MADA3KP11A datasheet specifies this parameter in the Electrical Characteristics table on Page 3.
Is MADA3KP11A RoHS compliant?
Yes, MADA3KP11A is RoHS compliant, indicated by the "e3" suffix in its full part marking per the nomenclature guide on Page 2. The device uses annealed matte-tin plating on terminals and conforms to IPC/JEDEC J-STD-020B moisture sensitivity Level 1, eliminating dry pack requirements. This compliance is confirmed in the Mechanical and Packaging section of the RF01243 Rev B datasheet.
How is polarity identified on the MADA3KP11A package?
Polarity on MADA3KP11A is identified by a dot marking on the top surface of the DO-214AB package, which designates Pin 1 as the cathode. As a unidirectional TVS, Pin 1 connects to the line being protected (e.g., +11 V rail), and Pin 2 serves as the anode, typically tied to ground. This marking convention is explicitly stated in the Mechanical and Packaging section on Page 2 of the RF01243 Rev B datasheet.
What is the maximum operating temperature range for MADA3KP11A?
MADA3KP11A operates across a junction and storage temperature range of –55 °C to +150 °C, as specified in the Maximum Ratings table on Page 2 of the RF01243 Rev B datasheet. This wide range supports deployment in under-hood automotive, industrial motor control, and outdoor telecom infrastructure where ambient temperatures exceed standard commercial limits.
Does MADA3KP11A require derating at elevated temperatures?
Yes, MADA3KP11A requires derating of its peak pulse power (PPP) above 25 °C, as shown in Figure 3 (Derating Curve) on Page 5 of the RF01243 Rev B datasheet. At +125 °C, its PPP rating drops to approximately 50% of the 3000 W 25 °C value. Designers must apply this derating when calculating surge margin in high-temperature environments such as enclosed power enclosures or engine compartments.
