Product details
Overview
MADA3KP36CA 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/EFT protection. It features a 36 V reverse standoff voltage (VWM), 40.0–44.2 V breakdown voltage (V(BR)), 58.1 V maximum clamping voltage at 51.6 A peak pulse current, and operates from −55 °C to +150 °C.
For engineers reviewing the MADA3KP36CA datasheet, MADA3KP36CA pinout, MADA3KP36CA application, or MADA3KP36CA equivalent, this device serves as a robust, RoHS-compliant TVS solution for industrial power interfaces, telecom line cards, and automotive control modules requiring IEC 61000-4-2/4-4/4-5 compliance with 2 Ω, 12 Ω, or 42 Ω source impedance configurations.
Technical Context
The MADA3KP36CA is a bidirectional TVS diode array built using silicon avalanche technology, delivering sub-nanosecond response time (<5 ns) and capable of suppressing transients up to 3000 W under 10/1000 μs waveform. Its clamping behavior is characterized by a maximum VC of 58.1 V at IPP = 51.6 A, with standby leakage ID ≤2 μA at VWM = 36 V.
It complies with IEC 61000-4-5 for secondary lightning protection across Class 1–4 when configured with 42 Ω source impedance, and supports Class 1–3 with 12 Ω and Class 2 only with 2 Ω source impedance - all verified per the manufacturer's test conditions and derating curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous operating voltage before clamping begins |
| V(BR) min/max | 40.0–44.2 V @ 1 mA - ensures reliable avalanche initiation within defined tolerance |
| VC @ IPP | 58.1 V @ 51.6 A - limits downstream voltage stress during 10/1000 μs surge |
| PPP | 3000 W @ 10/1000 μs - defines peak transient energy handling capability |
| ID @ VWM | ≤2 μA - negligible leakage current preserves system power integrity |
| TJ/TSTG | −55 °C to +150 °C - enables deployment in extended-temperature industrial and automotive environments |
| Polarity | Bidirectional - protects AC-coupled or dual-polarity signal/power lines without polarity biasing |
Pinout & Package
MDA3KP36CA uses a 3-pin SMC (DO-214AB) surface-mount package with cathode-defined pin numbering: Pin 1 and Pin 3 are cathodes; Pin 2 is the common anode. The package is void-free thermosetting epoxy (UL94V-0), tin-plated terminals, and marked with date code and part number; polarity dot identifies Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (TVS1) | Connects to protected line 1; forms one half of bidirectional clamp path |
| Pin 2 | Common Anode | Shared reference node; ties both TVS junctions to ground or return path |
| Pin 3 | Cathode (TVS2) | Connects to protected line 2; completes symmetrical bidirectional clamping |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetric overvoltage clamping on AC or differential signal lines without external biasing |
| 3000 W peak pulse power | Withstands high-energy surges such as induced lightning transients in telecom and industrial power rails |
| IEC 61000-4-5 Class 1–4 compliance | Validated for secondary lightning protection with 42 Ω, 12 Ω, and 2 Ω source impedances per test configuration |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life constraints for standard SMT assembly |
| RoHS-compliant (e3 marking) | Meets global environmental regulations without compromising surge performance or reliability |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package | Lower energy handling; suitable for board-level ESD only, not secondary lightning | Select when surge duty cycle is low and peak current <15 A |
| SMCJ36CA | 1500 W PPP, same VWM and polarity, DO-214AB package, 50% lower clamping voltage (VC = 58.1 V → 53.3 V) | Insufficient for Class 4 IEC 61000-4-5 with 42 Ω source; limited to Class 1–2 | Choose if space-constrained layout requires identical footprint but lower cost and moderate surge exposure |
Compared with SMBJ36CA and SMCJ36CA, the MADA3KP36CA delivers double the pulse power rating of SMCJ36CA and five times that of SMBJ36CA, enabling validated Class 4 secondary lightning protection - critical for infrastructure-grade equipment where single-event robustness is non-negotiable.

FAQ
What is the clamping voltage of MADA3KP36CA at its rated peak pulse current?
The MADA3KP36CA has a maximum clamping voltage (VC) of 58.1 V at its rated peak pulse current (IPP) of 51.6 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 circuits during worst-case surge events. The MADA3KP36CA maintains this clamping performance across its full operating temperature range.
Is MADA3KP36CA suitable for IEC 61000-4-5 Class 4 secondary lightning protection?
Yes, the MADA3KP36CA is explicitly rated for IEC 61000-4-5 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 also supports Class 1–3 with 12 Ω and Class 2 only with 2 Ω source impedance - all validated per manufacturer test methodology.
What does the 'C' suffix in MADA3KP36CA indicate?
The 'C' suffix in MADA3KP36CA denotes bidirectional polarity, meaning the device provides symmetrical clamping for both positive and negative transients across its two cathode terminals (Pins 1 and 3) referenced to the common anode (Pin 2). This distinguishes it from unidirectional variants like MADA3KP36A and enables use on AC-coupled or floating signal lines without external biasing.
What is the maximum operating temperature range for MADA3KP36CA?
The MADA3KP36CA is rated for junction and storage temperatures from −55 °C to +150 °C, as specified in the Maximum Ratings table on page 2 of the RF01243 datasheet. This extended thermal range supports deployment in under-hood automotive modules, outdoor telecom cabinets, and industrial motor drives where ambient temperatures exceed standard commercial limits.
Does MADA3KP36CA require dry-pack packaging or moisture barrier bags?
No, the MADA3KP36CA has IPC/JEDEC J-STD-020B moisture sensitivity level (MSL) 1, meaning it is exempt from dry-pack requirements and has unlimited floor life under standard factory conditions. This eliminates baking steps and humidity-controlled storage, simplifying SMT assembly and reducing manufacturing overhead for high-volume production of the MADA3KP36CA.
