Product details
Overview
MADA3KP20CA 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 20 V reverse standoff voltage (VWM), 22.2–24.5 V breakdown voltage (V(BR)), 32.4 V maximum clamping voltage at 92.6 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 and industrial power interfaces.
For engineers reviewing the MADA3KP20CA datasheet, MADA3KP20CA pinout, MADA3KP20CA application, or MADA3KP20CA equivalent, key selection criteria include bidirectional polarity, 3000 W 10/1000 µs surge rating, 20 V working voltage compatibility, clamping performance under 92.6 A, and MIL-PRF-19500 upscreening eligibility for aerospace-grade reliability assurance.
Technical Context
The MADA3KP20CA is a surface-mount, void-free epoxy-packaged TVS array with dual anode-cathode symmetrical structure enabling bidirectional clamping. Its sub-5 ns response time ensures effective suppression of fast transients including ESD and EFT events, while its 3000 W peak pulse power rating is validated per 10/1000 µs waveform with ≤0.05% duty cycle.
It complies with IEC61000-4-5 for secondary lightning protection across multiple source impedances (2 Ω, 12 Ω, 42 Ω), supporting Class 1–4 compliance depending on impedance configuration. Standby leakage current is limited to ≤2 µA at 20 V, and junction temperature range spans –55 °C to +150 °C for harsh-environment deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 20 V - Maximum continuous DC or peak AC voltage the device blocks without clamping |
| V(BR) min/max | 22.2–24.5 V @ 1 mA - Ensures reliable triggering above operating voltage with margin against false conduction |
| VC @ IPP | 32.4 V @ 92.6 A - Clamping voltage during worst-case 10/1000 µs surge; defines protected circuit's max overvoltage stress |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy transients common in industrial power line and telecom interface surges |
| ID @ VWM | ≤2 µA - Ultra-low leakage preserves system efficiency and avoids false trips in high-impedance sensing paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ20CA | 600 W PPP rating, same 20 V VWM and bidirectional polarity, DO-214AA package (smaller footprint) | Limited to lower-energy surges; unsuitable for IEC61000-4-5 Class 3/4 or 3000 W industrial transients | Select when board space is constrained and surge threat level is limited to ESD/EFT only. |
| 1.5KE20CA | 3000 W PPP but axial-leaded DO-15 package; higher thermal resistance and manual assembly requirement | Not suitable for automated SMT production; lacks MIL-PRF-19500 upscreening path | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMBJ20CA and 1.5KE20CA, the MADA3KP20CA delivers identical 20 V standoff and bidirectional operation while uniquely combining 3000 W SMT capability, sub-5 ns response, and upscreening eligibility-making it the only option qualified for high-reliability, high-surge, automated production environments.

FAQ
What is the clamping voltage of MADA3KP20CA at its rated peak pulse current?
The MADA3KP20CA has a maximum clamping voltage (VC) of 32.4 V at its rated peak pulse current (IPP) of 92.6 A under 10/1000 µs waveform conditions. This value is measured across the device terminals during surge conduction and defines the upper voltage limit imposed on protected circuitry. The MADA3KP20CA maintains this clamping performance consistently across its operating temperature range and after multiple surge events, provided derating per Figure 3 is observed.
Is MADA3KP20CA RoHS compliant?
Yes, MADA3KP20CA is RoHS compliant, indicated by the "e3" suffix in its full manufacturer marking per RF01243 Rev B. The device uses annealed matte-tin plating on terminals and void-free thermosetting epoxy packaging meeting UL94V-0. Compliance is verified per EU Directive 2011/65/EU, with no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits. Full material declarations and test reports are available upon request for MADA3KP20CA.
How does the bidirectional design of MADA3KP20CA affect its circuit implementation?
The bidirectional design of MADA3KP20CA allows it to clamp transients of either polarity between its two terminals without requiring orientation-specific placement. In practice, this means MADA3KP20CA can protect AC-coupled lines, differential buses like RS-485, or ungrounded DC rails where voltage reversals may occur. Unlike unidirectional TVS devices, MADA3KP20CA eliminates the need for back-to-back diode configurations or polarity-aware layout, simplifying PCB routing and reducing component count in symmetric protection schemes.
Can MADA3KP20CA be used for IEC61000-4-5 Class 4 lightning surge protection?
MADA3KP20CA supports IEC61000-4-5 Class 4 lightning protection only with 42 Ω source impedance, as confirmed in the Applications/Benefits section of RF01243 Rev B. It is not rated for Class 4 under 12 Ω or 2 Ω source impedances. For 42 Ω testing, MADA3KP20CA withstands the 4 kV open-circuit voltage waveform while limiting clamped voltage to ≤32.4 V. Designers must verify source impedance matching and coordinate with upstream filtering to ensure full Class 4 compliance in their system-level test plan for MADA3KP20CA.
What is the maximum operating temperature range for MADA3KP20CA?
The MADA3KP20CA is rated for junction and storage temperatures from –55 °C to +150 °C, as specified in the Maximum Ratings table of RF01243 Rev B. This extended range enables deployment in under-hood automotive electronics, outdoor telecom cabinets, and industrial motor drive enclosures where ambient temperatures exceed standard commercial limits. Derating of peak pulse power begins above 25 °C per Figure 3, requiring thermal design consideration in high-temperature environments using MADA3KP20CA.
