Product details
Overview
MADA3KP16CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in power and signal lines. It features a 16 V standoff voltage (VWM), 17.8–19.7 V breakdown range (V(BR)), 26.0 V maximum clamping voltage at 115.4 A peak pulse current, and operates across –55 °C to +150 °C for industrial and aerospace applications.
For engineers reviewing the MADA3KP16CAE3 datasheet, MADA3KP16CAE3 pinout, MADA3KP16CAE3 application, or MADA3KP16CAE3 equivalent, key selection criteria include IEC61000-4-5 secondary lightning compliance (Class 1–4 with 42 Ω source), ESD/EFT immunity per IEC61000-4-2/4-4, sub-5 ns response time, RoHS-compliant e3 plating, and surface-mount DO-214AB package compatibility.
Technical Context
The MADA3KP16CAE3 implements a silicon avalanche diode structure optimized for fast clamping of high-energy transients. Its bidirectional configuration enables symmetrical protection on AC lines or differential buses without polarity constraints, and its 10/1000 µs waveform rating supports IEC61000-4-5 Level 4 surge testing with 42 Ω source impedance.
It delivers <5 ns response time from 0 V to V(BR) min, maintains ≤2 µA standby current at 16 V, and sustains full 3000 W peak pulse power under 0.05% duty cycle conditions. The device is wafer lot traceable and undergoes 100% surge testing per production lot.
Key Specifications

Applications
| AC Power Input Protection | Industrial Ethernet Port Protection |
|---|---|
Use Scenario: 24 VAC or 120/230 VAC input stage of programmable logic controllers (PLCs) exposed to utility switching transients and nearby lightning coupling. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of bridge rectifier and bulk capacitor; absorbs energy before it reaches downstream regulators and microcontrollers. Use Value: Limits peak voltage to ≤26.0 V during 115.4 A surges, preventing damage to 30 V-rated input-stage MOSFETs and ensuring >100,000 surge cycles per IEC61000-4-5. | Use Scenario: RJ45 interface of industrial switches operating in factory-floor environments with frequent EFT bursts and cable-induced RF coupling. IC Role / Device Role / Timing Role: Bidirectional TVS array across differential pairs (e.g., TX+/TX–, RX+/RX–) and common-mode lines to suppress both differential and common-mode transients. Use Value: Sub-5 ns response clamps ESD events before PHY ICs latch-up; 2 µA leakage avoids signal integrity degradation on 100BASE-TX lines. |
| Avionics DC Bus Protection | Renewable Energy Inverter Control Board |
Use Scenario: 28 VDC main bus in airborne communication modules subject to MIL-STD-1275D transient profiles (spikes up to 100 V, 50 ms duration). IC Role / Device Role / Timing Role: Secondary surge limiter after primary LC filter; handles residual spikes that pass through front-end filtering due to limited inductor saturation current. Use Value: Withstands 150 °C ambient per MIL-PRF-19500 upscreening options; clamps 100 V spikes to <30 V within 5 ns, protecting FPGA configuration memory and ADC references. | Use Scenario: Gate driver supply rail (15 V) of solar inverter half-bridge modules exposed to stray inductive kickback from IGBT switching and grid fault coupling. IC Role / Device Role / Timing Role: Localized clamp on isolated gate drive transformer secondary output; protects high-side driver ICs from VCE spike coupling via parasitic capacitance. Use Value: 16 V VWM matches 15 V nominal rail with 6.7% margin; 26.0 V VC ensures gate oxide remains below 30 V absolute max rating during 115 A surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | 600 W PPP rating (vs. 3000 W); same VWM and bidirectional DO-214AA package. | Limited to lower-energy ESD/EFT; unsuitable for IEC61000-4-5 Class 3+ or lightning-survivable designs. | Select when cost-sensitive consumer-grade protection suffices and surge energy is constrained to <600 W. |
| SMCJ16CA | 1500 W PPP rating; identical DO-214AB footprint and VWM but lower clamping (24.4 V @ 61.5 A). | Meets IEC61000-4-5 Class 2–3 (42 Ω), but fails Class 4 due to insufficient energy handling. | Choose where board space allows same footprint but higher reliability than SMBJ is needed without full 3 kW capability. |
Compared with MADA3KP16CAE3, SMBJ16CA offers lower cost and smaller size but sacrifices 80% peak power handling, while SMCJ16CA provides intermediate robustness with tighter clamping but cannot replace MADA3KP16CAE3 in Class 4 lightning-critical systems.

FAQ
What is the maximum clamping voltage of MADA3KP16CAE3 at its rated peak pulse current?
The MADA3KP16CAE3 has a maximum clamping voltage (VC) of 26.0 V at its rated peak pulse current (IPP) of 115.4 A under 10/1000 µs waveform conditions. This value is guaranteed per datasheet Figure 2 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MADA3KP16CAE3 maintains this clamping performance across its full operating temperature range.
Is MADA3KP16CAE3 suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MADA3KP16CAE3 is validated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse power rating and 26.0 V clamping voltage enable it to suppress 4 kV surges without failure. The MADA3KP16CAE3 must be mounted with appropriate PCB trace width and thermal relief to sustain repeated Class 4 events.
What does the 'C' and 'E3' suffix in MADA3KP16CAE3 indicate?
The 'C' suffix denotes bidirectional polarity, meaning the MADA3KP16CAE3 contains two back-to-back avalanche diodes for symmetrical AC or differential line protection. The 'E3' suffix indicates RoHS-compliant matte-tin plating per JEDEC J-STD-020B Level 1, eliminating dry-pack requirements and supporting lead-free reflow soldering. Both identifiers are defined in the Part Nomenclature section of the RF01243 datasheet.
How does MADA3KP16CAE3 differ from unidirectional variants like MDA3KP16AE3?
MADA3KP16CAE3 uses a bidirectional configuration for AC or differential signal protection, whereas MDA3KP16AE3 is unidirectional and intended for DC line clamping only. The MADA3KP16CAE3 exhibits symmetrical clamping in both polarities, while MDA3KP16AE3 clamps only in reverse bias and conducts forward current up to 4.0 V at 500 A. Their pinouts and package dimensions are identical, but circuit placement and application scope differ fundamentally.
What is the standby leakage current specification for MADA3KP16CAE3 at its rated standoff voltage?
The MADA3KP16CAE3 specifies a maximum standby current (ID) of 2 µA at its rated working standoff voltage (VWM) of 16 V and 25 °C, per Electrical Characteristics Table on page 3 of RF01243. This ultra-low leakage ensures minimal power loss in always-on systems and avoids false triggering in high-impedance sensing circuits. The MADA3KP16CAE3 maintains ≤5 µA ID across its full –55 °C to +150 °C operating range.
