Product details
Overview
MADA3KP26CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, designed for high-reliability secondary lightning protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD suppression per IEC61000-4-2, and EFT protection per IEC61000-4-4. It features a 26 V standoff voltage (VWM), 28.9–31.9 V breakdown range (V(BR)), 42.1 V max clamping voltage at 71.2 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MADA3KP26CA datasheet, MADA3KP26CA pinout, MADA3KP26CA application, or MADA3KP26CA equivalent, this device serves as a high-power, bidirectional surge protector for telecom interfaces, industrial control I/O, power supply inputs, and automotive body electronics where fast response (<5 ns), RoHS-compliant packaging, and MIL-PRF-19500 upscreening capability are required.
Technical Context
The MADA3KP26CA employs an avalanche diode structure optimized for sub-5 ns transient response and 3000 W peak pulse power handling at 10/1000 µs waveform. Its bidirectional configuration enables symmetrical clamping across both polarities without external circuitry, supporting AC-coupled signal lines and ungrounded systems.
It is characterized by low standby leakage (≤2 µA at 26 V), tight V(BR) tolerance (±5%), and full surge testing per production lot. The device meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity and is rated for solder reflow up to 260 °C for 10 seconds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 26 V - Maximum continuous operating voltage before clamping begins; matches 24 V nominal DC systems with margin. |
| V(BR) min/max | 28.9–31.9 V - Breakdown occurs within this range at 1 mA; ensures predictable turn-on with ±5% tolerance. |
| VC @ IPP | 42.1 V - Clamping voltage at 71.2 A peak pulse; limits downstream voltage stress during surge events. |
| IPP | 71.2 A - Peak impulse current supported at 10/1000 µs; defines maximum surge energy absorption capacity. |
| PPP | 3000 W - Peak pulse power rating; enables robust protection against lightning-induced transients and switching spikes. |
| TJ/TSTG | –55 to +150 °C - Extended temperature range supports operation in harsh industrial and automotive under-hood environments. |
| Response time | <5 ns - Bidirectional clamping latency; critical for suppressing ESD and fast-rising EFT pulses. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ26CA | 600 W PPP rating, same VWM and bidirectional configuration, DO-214AA package. | Limited to Class 2 lightning protection (IEC61000-4-5, 42 Ω); insufficient for Class 4 or high-energy industrial surges. | Select when lower cost and space-constrained PCBs prioritize footprint over 3000 W surge headroom. |
| SMCJ26CA | 1500 W PPP, identical DO-214AB package and VWM, but lower clamping voltage (40.5 V) and 101.6 A IPP. | Suitable for Class 3 lightning protection only; not validated for 2 Ω source impedance Class 2 per IEC61000-4-5. | Choose for mid-tier surge immunity where 1500 W suffices and tighter clamping improves system margin. |
Compared with SMBJ26CA and SMCJ26CA, the MADA3KP26CA delivers double the pulse power of SMCJ26CA and five times that of SMBJ26CA-enabling single-device Class 4 lightning compliance without parallel stacking, while maintaining identical board footprint and thermal interface requirements.

FAQ
What is the clamping voltage of the MADA3KP26CA at its rated peak pulse current?
The MADA3KP26CA has a maximum clamping voltage (VC) of 42.1 V at its rated peak pulse current (IPP) of 71.2 A under 10/1000 µs waveform conditions. This value is guaranteed across the full operating temperature range and ensures downstream components experience controlled overvoltage stress during surge events. The MADA3KP26CA maintains this clamping performance with <5 ns response time and minimal derating up to +125 °C.
Is the MADA3KP26CA RoHS-compliant and lead-free compatible?
Yes, the MADA3KP26CA is RoHS-compliant (designated by "e3" suffix) with annealed matte-tin plating on terminals, qualified for lead-free reflow soldering at 260 °C for 10 seconds per MIL-STD-750 Method 2026. Its UL94V-0 epoxy body and Level 1 moisture sensitivity eliminate dry-pack requirements, making it fully compatible with modern high-volume SMT assembly lines. The MADA3KP26CA meets all JEDEC J-STD-020B criteria without process modification.
Can the MADA3KP26CA be used for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, the MADA3KP26CA is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as confirmed in the official Microsemi application note RF01243 Rev B. Its 3000 W peak pulse power and 71.2 A IPP enable compliance without parallel devices. The MADA3KP26CA also supports Class 3 with 12 Ω and Class 2 with 2 Ω source impedance, covering full multi-level system-level surge testing.
What is the standoff voltage and breakdown voltage range for the MADA3KP26CA?
The MADA3KP26CA has a rated reverse standoff voltage (VWM) of 26 V and a minimum–maximum breakdown voltage (V(BR)) range of 28.9 V to 31.9 V at 1 mA test current. This ±5% tolerance ensures reliable turn-on margin above normal operating voltage while preventing premature conduction. The MADA3KP26CA's VWM aligns with 24 V nominal systems, and its V(BR) window guarantees consistent clamping behavior across production lots.
Does the MADA3KP26CA require upscreening for aerospace applications?
The MADA3KP26CA supports optional MIL-PRF-19500 upscreening-including wafer/lot traceability, 3σ standby current screening, and enhanced environmental testing-but standard-grade units are qualified for industrial and telecom use without upscreening. For flight-critical systems, upscreened MADA3KP26CA variants undergo additional burn-in and parametric verification. The base MADA3KP26CA remains fully functional and compliant in non-aerospace applications without added screening.
