Product details
Overview
MADA3KP14CA 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 protection. It features a 14 V reverse standoff voltage (VWM), 15.6–17.2 V breakdown voltage (V(BR)), 23.2 V maximum clamping voltage at 129.4 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MADA3KP14CA datasheet, MADA3KP14CA pinout, MADA3KP14CA application, or MADA3KP14CA equivalent, key selection criteria include IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω/2 Ω source impedances, bidirectional polarity, RoHS-compliant e3 marking, and 100 ps response time - critical for telecom power rails, industrial I/O interfaces, and automotive body control modules.
Technical Context
The MADA3KP14CA implements a silicon avalanche diode structure optimized for fast transient suppression with sub-100 ps response. Its bidirectional configuration enables symmetrical clamping on AC-coupled lines without polarity constraints, supporting both positive and negative surge events up to 3000 W under 10/1000 µs waveform conditions.
It meets MIL-PRF-19500 screening options for high-reliability applications and is surge-tested per JEDEC JESD22-A114E (ESD) and JESD22-A115A (EFT). Standby leakage is limited to ≤2 µA at 14 V, ensuring minimal impact on low-power signal integrity in protected circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 14 V - Maximum continuous operating voltage before clamping begins; matches 12 V nominal rail systems with margin. |
| V(BR) min/max | 15.6–17.2 V - Confirmed breakdown range at 1 mA; ensures predictable turn-on above normal operating transients. |
| VC @ IPP | 23.2 V at 129.4 A - Clamping voltage during worst-case 10/1000 µs surge; defines maximum stress on downstream ICs. |
| PPP | 3000 W - Peak pulse power handling capability; supports IEC61000-4-5 Level 4 with 42 Ω source impedance. |
| ID @ VWM | ≤2 µA - Ultra-low leakage at rated standoff; preserves battery life and signal accuracy in always-on sensors. |
| TJ/TSTG | –55 °C to +150 °C - Extended thermal range enables use in under-hood automotive and industrial motor drive environments. |
Pinout & Package
Package: Surface-mount DO-214AB (SMC) molded epoxy case, void-free UL94V-0 compliant, ~5 g weight, RoHS-compliant matte-tin plating, polarity defined by dot marking indicating Pin 1 (cathode for unidirectional; symmetric for bidirectional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (Bidirectional Terminal A) | One side of symmetrical avalanche junction; connects to line under protection (e.g., RS-485 A or CAN_H). |
| Pin 2 | Cathode (Bidirectional Terminal B) | Other side of symmetrical junction; connects to return/reference (e.g., RS-485 B or CAN_L); no polarity dependency. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC or differential signal lines (e.g., USB D+/D–, RS-422) without external polarity routing. |
| 3000 W peak pulse rating | Withstands IEC61000-4-5 4 kV surge (42 Ω source) without degradation - validated per Figure 1 derating curve. |
| 100 ps response time | Clamps ESD events (IEC61000-4-2 ±8 kV contact) before sensitive logic states are corrupted. |
| MIL-PRF-19500 screening option | Supports high-reliability aerospace/defense programs requiring lot traceability, 3σ ID screening, and wafer-level conformance. |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |

Use Value: Eliminates need for discrete Zener+capacitor networks, reducing BOM count by 2 components and PCB area by 32 mm². |
| Telecom Power Feeds | Medical Imaging Sensor Interfaces |
Use Scenario: Safeguarding 48 V PoE-powered Ethernet PHYs from induced lightning surges on outdoor cabling. IC Role / Device Role / Timing Role: First-stage clamp on DC feed line, limiting energy delivered to secondary TVS and DC-DC converter input stage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ14CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA (SMB) package (smaller footprint, lower thermal mass) | Limited to IEC61000-4-5 Class 2 (2 kV) due to lower energy handling; unsuitable for 42 Ω source impedance testing | Select when space-constrained and surge threat level is ≤2 kV; verify thermal dissipation in enclosed enclosures. |
| 1.5KE14CA | 3000 W PPP, axial-leaded DO-15 package, higher junction-to-ambient thermal resistance (70 °C/W vs. 35 °C/W for SMC) | Not suitable for automated SMT assembly; requires wave soldering or hand-soldering; incompatible with high-vibration environments | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMBJ14CA and 1.5KE14CA, the MADA3KP14CA delivers superior surge robustness in SMT form factor - enabling Class 4 lightning protection without layout redesign, while its lower thermal resistance supports sustained operation in sealed industrial enclosures above 70 °C.

FAQ
What is the clamping voltage of the MADA3KP14CA at its rated peak pulse current?
The MADA3KP14CA has a maximum clamping voltage (VC) of 23.2 V at its rated peak pulse current (IPP) of 129.4 A under 10/1000 µs waveform conditions. This value is measured per JEDEC standards and guarantees that downstream circuitry sees no more than 23.2 V during worst-case surge events - critical for protecting 24 V-rated interface ICs such as MAX3232E.
Is the MADA3KP14CA compatible with lead-free reflow soldering processes?
Yes, the MADA3KP14CA supports lead-free reflow soldering with a peak temperature of 260 °C for 10 seconds, per MIL-STD-750 Method 2026. Its tin-lead or annealed matte-tin plating ensures reliable wetting, and the UL94V-0 epoxy body withstands thermal cycling without delamination - confirmed in Microsemi's RF01243 Rev B qualification report.
How does the bidirectional design of the MADA3KP14CA affect its use in differential signal lines?
The bidirectional design of the MADA3KP14CA allows it to protect differential pairs like RS-485 or CAN without regard to signal polarity. Unlike unidirectional TVS arrays, it clamps both positive and negative transients equally - eliminating the need for dual devices or external biasing, and preserving common-mode rejection ratio (CMRR) in balanced receivers such as SN65HVD72.
Can the MADA3KP14CA be used for IEC61000-4-2 ESD protection alone, or is additional circuitry required?
The MADA3KP14CA provides standalone ESD protection per IEC61000-4-2 (±8 kV contact, ±15 kV air) due to its <100 ps response time and low clamping voltage. No series impedance or filtering is required for basic compliance, though a 100 nF ceramic capacitor may be added in parallel for enhanced high-frequency energy absorption in medical-grade designs.
What is the meaning of the "C" suffix in MADA3KP14CA?
The "C" suffix in MADA3KP14CA explicitly denotes bidirectional polarity per Microsemi's part nomenclature (RF01243 Rev B, Page 2). It distinguishes this variant from unidirectional versions like MADA3KP14A, confirming symmetrical avalanche behavior across both terminals - essential for AC-coupled or floating signal paths where polarity reversal occurs.
