Product details
Overview
MADA3KP9.0CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability secondary lightning and ESD protection. It features a 9.0 V reverse standoff voltage (VWM), 10.0–11.1 V breakdown voltage (V(BR)), 15.4 V maximum clamping voltage (VC) at 194.8 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MADA3KP9.0CAE3 datasheet, MADA3KP9.0CAE3 pinout, MADA3KP9.0CAE3 application, or MADA3KP9.0CAE3 equivalent, key selection criteria include IEC61000-4-5 Class 4 compliance with 2 Ω source impedance, bidirectional polarity, RoHS-compliant matte-tin plating, and 100 ps response time - all critical for industrial power interface and telecom surge protection design.
Technical Context
The MADA3KP9.0CAE3 is a monolithic silicon avalanche diode array configured as a bidirectional TVS, enabling symmetrical clamping of positive and negative transients without external polarity management. Its construction supports full IEC61000-4-5 compliance up to Class 4 under 2 Ω source impedance, with verified 3000 W peak pulse power handling at 10/1000 μs waveform.
It delivers sub-100 ps response time and low standby leakage (<10 μA at VWM), making it suitable for protecting sensitive analog and digital interfaces in harsh electromagnetic environments. The device undergoes 100% surge testing and lot-level traceability per MIL-PRF-19500 screening options.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum continuous operating voltage before clamping begins; matches 9 V rail systems. |
| V(BR) min/max | 10.0–11.1 V @ 1 mA - Ensures reliable avalanche initiation within tight tolerance for predictable protection threshold. |
| VC @ IPP | 15.4 V @ 194.8 A - Clamping voltage limits downstream component stress during worst-case 10/1000 μs surge. |
| PPP | 3000 W @ 10/1000 μs - Sustains high-energy transients typical of lightning-induced surges in industrial fieldbus lines. |
| TJ range | –55 °C to +150 °C - Enables deployment in extended-temperature automotive engine control and outdoor telecom enclosures. |
| ID @ VWM | <10 μA - Minimizes quiescent power loss and avoids false triggering in low-power sensor nodes. |
| Response time | <100 ps - Faster than most microcontrollers' I/O damage thresholds, ensuring effective ESD immunity per IEC61000-4-2. |
Pinout & Package
Package: Surface-mount DO-214AB (SMC) case with void-free UL94V-0 epoxy body, matte-tin-plated terminals, and polarity defined by dot marking on top (Pin 1 = cathode for each channel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Channel A) | Common cathode connection for first TVS element; ties to protected line in bidirectional configuration. |

IC Role / Device Role / Timing Role: Primary surge suppression device on input side of DC-DC converters, rated for IEC61000-4-5 Class 4 with 2 Ω source. Use Value: Maintains system uptime by absorbing 3000 W transients without degradation, validated across –55 °C to +150 °C operating range. |
| RS-485 Fieldbus Nodes | Automotive Body Control Modules |
Use Scenario: Securing differential data lines in factory automation networks exposed to EFT bursts and ground potential differences. IC Role / Device Role / Timing Role: Bidirectional TVS connected between A/B lines and ground, leveraging fast <100 ps response to suppress EFT per IEC61000-4-4. Use Value: Prevents communication lockup by clamping transients before they exceed receiver input absolute maximum ratings (±12 V). | Use Scenario: Protecting LIN bus transceivers and sensor inputs in under-hood modules subject to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Standoff-rated TVS on 12 V supply rails and signal pins, selected for 9.0 V VWM to align with nominal battery voltage. Use Value: Survives repeated 3000 W surges while maintaining <10 μA leakage, preserving battery life in always-on vehicle subsystems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0CA | Lower PPP rating (600 W), same VWM and bidirectional polarity, SMB package (smaller footprint, lower thermal mass). | Not qualified for IEC61000-4-5 Class 4 (2 Ω); limited to Class 2/3 or lower-energy ESD/EFT scenarios. | Select when board space is constrained and surge energy remains below 600 W - not a drop-in replacement for MADA3KP9.0CAE3's 3000 W requirement. |
| 1.5KE9.1C | Through-hole DO-201 package, 1500 W PPP, 9.1 V VWM, higher clamping voltage (14.5 V min). | Lacks MIL-PRF-19500 screening option and RoHS e3 marking; unsuitable for high-reliability surface-mount production. | Use only for prototyping or legacy through-hole designs where 3000 W capability and SMT assembly are not required. |
Compared with SMBJ9.0CA and 1.5KE9.1C, the MADA3KP9.0CAE3 uniquely combines 3000 W surge capacity, bidirectional SMT packaging, Class 4 lightning compliance, and MIL-qualified screening readiness - making it the sole choice for high-energy, high-reliability industrial and telecom surge protection.

FAQ
What is the clamping voltage of MADA3KP9.0CAE3 at its rated peak pulse current?
The MADA3KP9.0CAE3 has a maximum clamping voltage (VC) of 15.4 V at its rated peak pulse current (IPP) of 194.8 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 MADA3KP9.0CAE3 achieves this performance using monolithic silicon avalanche structure with tightly controlled breakdown characteristics.
Is MADA3KP9.0CAE3 suitable for IEC61000-4-5 Class 4 testing with 2 Ω source impedance?
Yes, the MADA3KP9.0CAE3 is explicitly rated for IEC61000-4-5 Class 4 compliance when tested with a 2 Ω source impedance, as confirmed in the official Microsemi datasheet RF01243 Rev B. This makes the MADA3KP9.0CAE3 appropriate for high-severity surge environments such as outdoor telecom cabinets and industrial control panels. Its 3000 W peak pulse power rating directly supports this classification.
What does the "C" and "e3" suffix mean in MADA3KP9.0CAE3?
In MADA3KP9.0CAE3, the "C" denotes bidirectional polarity, meaning the device provides symmetrical clamping for both positive and negative transients. The "e3" indicates RoHS-compliant matte-tin plating per JEDEC J-STD-020B, with moisture sensitivity level 1 and no dry pack required. These markings are integral to the Microsemi part nomenclature and confirm the MADA3KP9.0CAE3's suitability for lead-free reflow and environmentally regulated production.
How does MADA3KP9.0CAE3 differ from unidirectional variants like MDA3KP9.0AE3?
The MADA3KP9.0CAE3 is bidirectional, while MDA3KP9.0AE3 is unidirectional - a fundamental difference affecting circuit topology and protection scope. The MADA3KP9.0CAE3 clamps transients on both polarities across a single pair of terminals, ideal for AC or floating lines; MDA3KP9.0AE3 protects only one polarity and requires separate devices or additional diodes for full protection. Their VWM, VC, and PPP values are otherwise closely matched.
What is the junction temperature range and thermal derating behavior of MADA3KP9.0CAE3?
The MADA3KP9.0CAE3 operates across a junction temperature range of –55 °C to +150 °C, with peak pulse power derated linearly above 25 °C per the curve in Figure 3 of RF01243 Rev B. At 100 °C, its 3000 W rating reduces to approximately 70%, or ~2100 W. This derating ensures safe operation in high-ambient environments such as enclosed power supplies or under-hood automotive modules where the MADA3KP9.0CAE3 is commonly deployed.
