Product details
Overview
MADA3KP22AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in industrial power interfaces. It features a 22 V reverse standoff voltage (VWM), 24.4–26.9 V breakdown voltage (V(BR)), 35.5 V maximum clamping voltage at 84.4 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MADA3KP22AE3 datasheet, MADA3KP22AE3 pinout, MADA3KP22AE3 application, or MADA3KP22AE3 equivalent, key selection criteria include clamping performance under IEC61000-4-5 (42 Ω source, Class 1–4), surge robustness up to 3000 W @ 10/1000 µs, RoHS-compliant e3 termination, and compatibility with MIL-PRF-19500 upscreening options.
Technical Context
The MADA3KP22AE3 implements a silicon avalanche diode structure optimized for fast response (<100 ps rise time) and low clamping ratio (VC/V(BR) ≈ 1.4). Its unidirectional polarity enables DC-biased protection paths without reverse leakage concerns above VWM.
Rated for 3000 W peak pulse power per 10/1000 µs waveform, it delivers 84.4 A IPP while maintaining ≤35.5 V clamping-critical for safeguarding 24 V industrial control inputs, PoE power rails, and RS-485 transceivers against induced surges and switching transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22 V maximum working standoff voltage - sets upper limit of continuous operating voltage before conduction begins |
| V(BR) min/max | 24.4–26.9 V breakdown range at 1 mA - defines precise turn-on threshold for transient clamping |
| VC @ IPP | 35.5 V max clamping voltage at 84.4 A - ensures protected ICs see no more than 35.5 V during worst-case surge |
| IPP | 84.4 A peak pulse current - quantifies maximum surge energy absorption capability per IEC61000-4-5 |
| ID @ VWM | ≤2 µA standby leakage - negligible power loss and signal integrity impact in always-on monitoring circuits |
| TJ range | –55 °C to +150 °C operating junction temperature - supports deployment in harsh automotive and industrial environments |
| PPP | 3000 W peak pulse power @ 10/1000 µs - meets IEC61000-4-5 Level 4 secondary lightning requirements with 42 Ω source |
Pinout & Package
Package: DO-214AB (SMC) molded epoxy case, void-free UL94V-0 compliant, 5 g weight, tin-lead or matte-tin plating, pin 1 marked by dot on top surface. Polarity: Pin 1 = cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; conducts surge current to ground when voltage exceeds V(BR) |
| Pin 2 | Anode | Connected to system ground reference; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W surge rating | Enables single-device protection against IEC61000-4-5 Class 4 secondary lightning (42 Ω source) without parallel staging |

| MIL-PRF-19500 upscreening option | Supports high-reliability qualification including lot traceability, 3σ ID screening, and surge testing per military-grade requirements |
| Level 1 moisture sensitivity | Eliminates dry-pack requirement and floor-life constraints-ready for standard SMT assembly without baking |
| Fast <100 ps response | Clamps ESD events (IEC61000-4-2) before sensitive logic or analog circuitry sustains damage |
Applications
| Industrial PLC I/O Protection | 24 V DC Power Rail Protection |
|---|---|
Use Scenario: Protecting digital input modules in programmable logic controllers exposed to field-wiring-induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input terminal and ground to clamp transients before reaching optocoupler or MCU GPIO. Use Value: Maintains signal integrity under 84.4 A surges while limiting clamped voltage to ≤35.5 V-well below 40 V absolute maximum ratings of common industrial interface ICs. | Use Scenario: Safeguarding 24 V supply lines feeding motor drivers, sensors, and communication ICs in factory automation equipment. IC Role / Device Role / Timing Role: Primary surge suppression device installed at power entry point, upstream of DC-DC converters and LDOs. Use Value: Absorbs 3000 W pulses without degradation, preventing brownouts or latch-up in downstream regulators due to voltage overshoot. |
| RS-485 Transceiver Protection | PoE Power Sourcing Equipment (PSE) |
Use Scenario: Shielding half-duplex RS-485 bus nodes from cable-coupled noise and lightning-induced common-mode transients. IC Role / Device Role / Timing Role: Paired unidirectional TVS devices on A/B lines referenced to ground, leveraging low clamping voltage to preserve differential signaling margin. Use Value: Clamps to 35.5 V within <100 ps, preserving >1.5 V differential noise margin even during 1 kV/500 A surge events. | Use Scenario: Protecting IEEE 802.3af/at PSE controller ICs and MOSFET switches from Ethernet cable surge coupling and hot-swap transients. IC Role / Device Role / Timing Role: Line-side TVS on power pair (spare or data pairs) to divert surge energy before reaching active switch FETs or sense resistors. Use Value: Withstands repeated 10/1000 µs surges up to 3000 W-ensuring PSE remains operational after multiple lightning-induced events per IEC61000-4-5. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22A | 600 W rating, 30 A IPP, same VWM and VC but lower power handling | Suitable for lower-energy ESD/EFT only-not rated for IEC61000-4-5 Class 4 lightning | Select when board space is constrained and surge threat level is limited to IEC61000-4-2/4-4 |
| 1.5KE22A | Through-hole TO-218 package, 1500 W rating, higher thermal mass but incompatible mounting | Requires PCB redesign; used where legacy through-hole layout or higher thermal cycling endurance is required | Choose only if existing design uses axial/TO-218 footprint and cannot accommodate SMC package |
Compared with SMBJ22A and 1.5KE22A, MADA3KP22AE3 uniquely delivers 3000 W surge capacity in a surface-mount SMC package with MIL-PRF-19500 upscreening support-making it the only option qualified for high-reliability industrial lightning protection without layout change or derating.

FAQ
What is the clamping voltage of MADA3KP22AE3 at its rated peak pulse current?
The MADA3KP22AE3 has a maximum clamping voltage (VC) of 35.5 V at its rated peak pulse current (IPP) of 84.4 A under 10/1000 µs waveform conditions. This value is guaranteed across temperature and ensures protected circuitry remains within safe voltage limits during surge events. The MADA3KP22AE3 achieves this clamping performance while maintaining low leakage and fast response, making it suitable for 24 V industrial systems.
Is MADA3KP22AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MADA3KP22AE3 is RoHS compliant-the 'e3' suffix explicitly denotes matte-tin plating per J-STD-609, confirming lead-free termination compatible with Pb-free reflow processes. This compliance is verified per Microsemi's documentation and applies to both solderability and environmental regulatory requirements. The MADA3KP22AE3 maintains full electrical specifications under RoHS-compliant assembly conditions.
Can MADA3KP22AE3 be used for bidirectional protection?
No, MADA3KP22AE3 is unidirectional only, as indicated by the absence of 'C' in its part number. Bidirectional variants (e.g., MADA3KP22CE3) exist but differ in V(BR) symmetry and leakage behavior. Using MADA3KP22AE3 in AC-coupled or floating applications risks reverse conduction failure. Always select the 'C' suffix version for true bidirectional clamping needs. The MADA3KP22AE3 must be oriented with cathode toward the protected line.
What is the maximum operating temperature range for MADA3KP22AE3?
MADA3KP22AE3 is rated for junction temperatures from –55 °C to +150 °C, enabling operation in extreme environments such as engine compartments, outdoor telecom cabinets, and industrial ovens. Derating curves (Figure 3 in RF01243) define power reduction above 25 °C ambient. The MADA3KP22AE3 retains full 3000 W surge capability at 25 °C and remains functional-even at 150 °C-with appropriate thermal design and reduced pulse repetition rates.
Does MADA3KP22AE3 meet IEC61000-4-5 for secondary lightning protection?
Yes, MADA3KP22AE3 is validated for IEC61000-4-5 secondary lightning protection up to Class 4 with 42 Ω source impedance, and Class 3 with 12 Ω and 2 Ω sources. Its 3000 W PPP rating and 84.4 A IPP directly satisfy the 1 kV/2 kA test levels defined in the standard. The MADA3KP22AE3 achieves this performance without external components, simplifying system-level EMC certification for industrial and infrastructure equipment.
