Product details
Overview
MADA3KP24CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in industrial and aerospace systems. It features a 24 V reverse standoff voltage (VWM), 26.7–29.5 V breakdown voltage (V(BR)), 38.9 V maximum clamping voltage at 77.2 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MADA3KP24CA datasheet, MADA3KP24CA pinout, MADA3KP24CA application, or MADA3KP24CA equivalent, key selection criteria include IEC61000-4-5 secondary lightning protection with 42 Ω/12 Ω/2 Ω source impedances, ESD/EFT compliance per IEC61000-4-2/4-4, and bidirectional clamping behavior for AC-coupled signal lines.
Technical Context
The MADA3KP24CA implements a silicon avalanche diode structure optimized for sub-5 ns response time and low clamping ratio (VC/VWM ≈ 1.62). Its bidirectional configuration enables symmetrical transient suppression on differential or AC power rails without polarity constraints.
It delivers 3000 W peak pulse power at 10/1000 μs waveform, supports 200 A forward surge current (IFSM), and maintains <2 μA standby current at 24 V standoff-enabling low-power system monitoring while preserving robust surge immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - Maximum continuous operating voltage before conduction begins; sets minimum system voltage margin for reliable standby operation. |
| V(BR) min/max | 26.7–29.5 V - Breakdown occurs within this range at 1 mA; defines precise turn-on threshold for predictable clamping onset. |
| VC @ IPP | 38.9 V - Clamping voltage at 77.2 A peak pulse; determines maximum voltage stress imposed on protected downstream circuitry. |
| IPP | 77.2 A - Peak impulse current supported at 10/1000 μs waveform; quantifies surge energy handling capacity. |
| PPP | 3000 W - Peak pulse power rating; confirms suitability for Class 1–4 IEC61000-4-5 secondary lightning events. |
| TJ range | –55 °C to +150 °C - Full military-grade thermal operating envelope; validated for avionics and downhole equipment. |
| ID @ VWM | 2 μA - Standby leakage at rated standoff; ensures minimal quiescent power draw in battery-backed or low-power sensor nodes. |
Pinout & Package
Package: DO-214AB (SMC) surface-mount plastic case, void-free thermosetting epoxy meeting UL94V-0; dimensions 21.03 × 6.86 × 8.64 mm (L × W × H); weight ~5 g; polarity marked with dot indicating Pin 1 as cathode for each TVS element.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (TVS1) | Reference terminal for first bidirectional TVS element; connects to protected line requiring clamping to ground or rail. |
| Pin 2 | Anode (TVS1) / Cathode (TVS2) | Center tap node enabling dual-line bidirectional protection; forms common connection between two opposing diodes. |
| Pin 3 | Anode (TVS2) | Reference terminal for second bidirectional TVS element; completes symmetrical clamping path across differential pair or AC line. |

|---|---|
| Bidirectional construction | Enables symmetric clamping on AC signals or differential buses without external polarity management circuitry. |
| 3000 W peak pulse power | Supports full IEC61000-4-5 Class 4 secondary lightning testing with 42 Ω source impedance. |
| Sub-5 ns response time | Clamps ESD transients (IEC61000-4-2) before sensitive ICs experience latch-up or gate oxide damage. |
| MIL-PRF-19500 screening option | Enables high-reliability qualification for aerospace and defense programs requiring lot traceability and 3σ ID screening. |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing cost and process complexity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | 600 W PPP rating, same VWM and bidirectional polarity, but lower IPP (32.4 A) and higher VC (38.9 V vs. 38.9 V - identical value but lower energy margin). | Not qualified for MIL-PRF-19500 screening; lacks high-reliability wafer traceability and 3σ ID screening. | Select when cost sensitivity outweighs military/aerospace qualification requirements and surge energy remains below 600 W. |
| 1.5KE24CA | Through-hole TO-218 package, same VWM and bidirectional function, but slower response (>10 ns), higher thermal resistance, and no moisture Level 1 rating. | Not suitable for automated SMT assembly; requires wave soldering and post-process cleaning; incompatible with high-density PCB layouts. | Select only for legacy through-hole designs where board real estate and reflow compatibility are not constraints. |
Compared with SMBJ24CA and 1.5KE24CA, the MADA3KP24CA provides 5× higher peak pulse power, certified SMT process compatibility, and MIL-PRF-19500 upscreening capability-making it the sole choice for mission-critical 24 V systems requiring Class 4 lightning immunity and full production traceability.

FAQ
What is the clamping voltage of MADA3KP24CA at its rated peak pulse current?
The MADA3KP24CA has a maximum clamping voltage (VC) of 38.9 V at its rated peak pulse current (IPP) of 77.2 A under 10/1000 μs waveform conditions. This value is measured per standard test methods defined in the datasheet and represents the upper bound of voltage seen by protected circuitry during worst-case surge events. The MADA3KP24CA maintains this clamping performance across its full operating temperature range.
Is MADA3KP24CA suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, the MADA3KP24CA is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance. Its 3000 W peak pulse power rating and 77.2 A IPP capability meet the 6 kV open-circuit voltage requirement for Class 4. The MADA3KP24CA's bidirectional architecture ensures symmetrical clamping during both polarities of the lightning surge waveform.
Does MADA3KP24CA require dry packing or baking before reflow soldering?
No, the MADA3KP24CA has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ambient conditions and does not require dry packing, vacuum sealing, or pre-reflow baking. This eliminates process steps and reduces manufacturing risk-confirmed in the official Microsemi documentation for the MDA3KP series.
What is the polarity configuration of MADA3KP24CA and how does it affect circuit placement?
The MADA3KP24CA is a bidirectional TVS array with three terminals: Pin 1 (cathode), Pin 2 (center tap/anode-cathode junction), and Pin 3 (anode). This configuration allows it to clamp transients equally in both directions across any two pins, making it ideal for AC lines or differential signals. The MADA3KP24CA must be placed with Pin 2 connected to the reference plane (e.g., ground or common rail) and Pins 1 and 3 tied to the protected lines.
Can MADA3KP24CA be used in aerospace applications requiring MIL-PRF-19500 screening?
Yes, optional MIL-PRF-19500 upscreening is available for the MADA3KP24CA, including wafer-level traceability, 3σ lot norm screening on standby current (ID), and conformance inspections per the specification. This makes the MADA3KP24CA suitable for flight-critical avionics and satellite power systems where component reliability and pedigree are mandated.
