Product details
Overview
MADA3KP22CA 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 22 V standoff voltage (VWM), 24.4–26.9 V breakdown range (V(BR)), 35.5 V maximum clamping voltage at 84.4 A peak pulse current, and operates across –55 °C to +150 °C. It protects industrial power supplies against IEC61000-4-5 secondary lightning surges with 42 Ω source impedance.
For engineers reviewing the MADA3KP22CA datasheet, MADA3KP22CA pinout, MADA3KP22CA application, or MADA3KP22CA equivalent, key selection criteria include bidirectional polarity, 3000 W 10/1000 µs surge rating, RoHS-compliant void-free epoxy package, and compatibility with MIL-PRF-19500 upscreening for aerospace-grade reliability validation.
Technical Context
The MADA3KP22CA implements a silicon avalanche diode structure optimized for sub-nanosecond response (<5 ns) to transient overvoltages. Its bidirectional configuration enables symmetrical clamping on both polarities without external circuitry, supporting AC line and differential signal protection.
It meets IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and IEC61000-4-5 (lightning) immunity standards under defined source impedances (2 Ω, 12 Ω, 42 Ω). Standby leakage is limited to ≤2 µA at 22 V, ensuring minimal impact on low-power circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22 V - Maximum continuous operating voltage before clamping begins; matches 24 V nominal DC systems. |
| V(BR) min/max | 24.4–26.9 V - Confirmed avalanche onset range at 1 mA; ensures predictable turn-on margin above VWM. |
| VC @ IPP | 35.5 V - Clamping voltage at 84.4 A peak pulse; limits downstream voltage stress during 10/1000 µs transients. |
| PPP | 3000 W - Peak pulse power handling per IEC61000-4-5 waveform; supports Class 1–4 lightning protection levels. |
| ID @ VWM | ≤2 µA - Ultra-low standby leakage; avoids loading in high-impedance sensor or battery-backed circuits. |
| TJ/TSTG | –55 °C to +150 °C - Extended thermal range enables use in under-hood automotive or industrial motor drive environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ22CA | 600 W PPP rating, SMA package, 38.9 V VC @ 32.4 A IPP | Lower energy handling; suitable only for Class 1–2 IEC61000-4-5, not Class 4 | Select when board space is constrained and surge threat level is limited to ESD/EFT only. |
| Vishay SM8S22CA | 6600 W PPP rating, DO-218AB package, 37.5 V VC @ 177 A IPP | Higher surge capacity but larger footprint and higher clamping voltage tolerance | Choose for enhanced lightning robustness where PCB layout allows larger SMD footprint and thermal mass. |
Compared with MADA3KP22CA, SMAJ22CA offers compact size but reduced surge endurance, while SM8S22CA provides superior energy absorption at the cost of board area and tighter layout constraints-making MADA3KP22CA optimal for balanced performance, reliability, and MIL-grade traceability in mission-critical systems.

FAQ
What is the clamping voltage of MADA3KP22CA at its rated peak pulse current?
The MADA3KP22CA 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 measured per Figure 2 in the official datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MADA3KP22CA maintains this clamping performance across its full operating temperature range.
Is MADA3KP22CA suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MADA3KP22CA is qualified 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. It delivers full 3000 W surge capability at this level, making it appropriate for telecom infrastructure and industrial control panels requiring highest immunity assurance. The MADA3KP22CA's bidirectional architecture ensures symmetrical protection without polarity concerns.
Does MADA3KP22CA require dry packing or special moisture handling?
No, MADA3KP22CA has IPC/JEDEC J-STD-020B moisture sensitivity Level 1 classification, meaning it does not require dry packing, baking, or floor-life monitoring prior to reflow soldering. Its void-free epoxy package inherently resists moisture ingress, enabling standard SMT processing and simplifying inventory logistics. This characteristic applies directly to the MADA3KP22CA and is verified in the Mechanical and Packaging section of the datasheet.
What is the polarity designation indicated by the 'C' suffix in MADA3KP22CA?
The 'C' suffix in MADA3KP22CA explicitly denotes bidirectional polarity, as defined in the Part Nomenclature section on page 2 of the RF01243 datasheet. This means the device contains two avalanche diodes connected in series opposition, allowing symmetrical clamping for both positive and negative transients. Unlike unidirectional variants (e.g., MADA3KP22A), the MADA3KP22CA requires no external polarity alignment and is ideal for AC-coupled or differential signal paths.
Can MADA3KP22CA be used in automotive under-hood applications?
Yes, MADA3KP22CA supports operation from –55 °C to +150 °C junction temperature, satisfying under-hood thermal requirements for engine control units and battery management systems. Its 3000 W surge rating and low leakage (≤2 µA at 22 V) make it suitable for protecting CAN transceivers, sensor interfaces, and DC-DC controllers against load dump and ISO 7637-2 pulses. The MADA3KP22CA's MIL-PRF-19500 upscreening option further validates its suitability for automotive safety-critical subsystems.
