Product details
Overview
MADA3KP14A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in power rails and signal lines. 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 from –55 °C to +150 °C. It is used in telecom power supplies and industrial control I/O interfaces.
For engineers reviewing the MADA3KP14A datasheet, MADA3KP14A pinout, MADA3KP14A application, or MADA3KP14A equivalent, key selection criteria include its 14 V VWM rating, 23.2 V clamping performance at 129.4 A, unidirectional polarity, RoHS-compliant void-free epoxy package, and compliance with IEC61000-4-2/4-4/4-5 surge immunity standards.
Technical Context
The MADA3KP14A is a single-channel unidirectional TVS diode optimized for fast clamping of high-energy transients using avalanche breakdown. Its <100 ps response time enables effective suppression of ESD events per IEC61000-4-2 and switching-induced surges in DC power distribution networks.
It is rated for 3000 W peak pulse power at 10/1000 µs waveform, with thermal derating above 25 °C per Figure 3. Standby leakage is limited to ≤2 µA at 14 V, ensuring minimal impact on system quiescent current in always-on applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 14 V - Maximum continuous DC or peak AC voltage the device blocks without conduction. |
| V(BR) min/max | 15.6–17.2 V @ 1 mA - Confirmed avalanche onset range; ensures predictable turn-on before downstream IC damage. |
| VC @ IPP | 23.2 V @ 129.4 A - Clamping voltage under full 3000 W surge; defines worst-case overvoltage seen by protected circuitry. |
| ID @ VWM | ≤2 µA - Ultra-low leakage preserves battery life and avoids false triggering in high-impedance sensing paths. |
| PPP | 3000 W @ 10/1000 µs - Sustains standardized lightning-surge energy without failure per IEC61000-4-5. |
| TJ/TSTG | –55 °C to +150 °C - Supports operation in harsh environments including automotive engine bays and industrial motor drives. |
Pinout & Package
Package: Void-free transfer-molded thermosetting epoxy case meeting UL94V-0; tin-lead or matte-tin plating; weight ≈5 g; polarity: Pin 1 = cathode (odd pins are cathodes per array configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; conducts during overvoltage to shunt current to ground. |
| Pin 2 | Anode | Connected to system ground; completes low-impedance path for surge current dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Withstands IEC61000-4-5 Class 4 secondary lightning surges (42 Ω source) without degradation. |
| Unidirectional construction | Protects DC-biased lines only in forward direction; avoids unintended conduction during normal negative excursions. |
| RoHS-compliant e3 marking | Meets global environmental regulations; uses annealed matte-tin plating compatible with lead-free reflow. |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life constraints-reduces handling overhead in SMT assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ14A | 600 W PPP rating; same VWM and VC but lower IPP (84.5 A); DO-214AA package. | Not suitable for IEC61000-4-5 Class 4; limited to Class 2/3 or lower-energy ESD/EFT. | Select SMBJ14A only when surge threat level is constrained and board space is critical. |
| SMCJ14A | 1500 W PPP; VC = 23.2 V at 64.5 A; larger SMC (DO-214AB) package; same VWM. | Supports IEC61000-4-5 Class 3 (42 Ω), but not Class 4; requires more PCB area than MADA3KP14A. | Choose SMCJ14A where cost is prioritized over peak surge margin and layout allows larger footprint. |
Compared with SMBJ14A and SMCJ14A, the MADA3KP14A delivers double the surge energy handling of SMCJ14A and five times that of SMBJ14A in the same footprint, enabling single-device Class 4 lightning protection without redesigning thermal or mechanical layout.

FAQ
What is the clamping voltage of the MADA3KP14A under maximum surge conditions?
The MADA3KP14A exhibits a maximum clamping voltage (VC) of 23.2 V when subjected to its rated peak pulse current of 129.4 A under 10/1000 µs waveform conditions. This value is guaranteed across temperature and represents the upper limit of overvoltage imposed on protected circuitry during a full 3000 W transient event. The MADA3KP14A maintains this clamping performance consistently due to its robust silicon die and low-inductance package design.
Is the MADA3KP14A suitable for bidirectional signal line protection?
No, the MADA3KP14A is a unidirectional TVS device intended for DC-biased or positive-only voltage rails. Its polarity is fixed: Pin 1 is cathode, Pin 2 is anode. For bidirectional AC or symmetrical signal lines, the MADA3KP14CA variant must be used instead. Using the MADA3KP14A on bidirectional lines risks forward conduction during negative half-cycles, potentially disrupting signal integrity or damaging upstream drivers.
Does the MADA3KP14A require special handling for moisture sensitivity?
No, the MADA3KP14A has IPC/JEDEC J-STD-020B moisture sensitivity level (MSL) 1, meaning it may be stored indefinitely at ambient conditions without dry packing or baking prior to reflow. This eliminates floor-life tracking and pre-conditioning steps in manufacturing, reducing process complexity and cost. The void-free epoxy body contributes to its inherent moisture resistance.
Can the MADA3KP14A replace older Microsemi TVS devices like the MDA3KP14A without layout changes?
Yes, the MADA3KP14A is a direct replacement for the legacy MDA3KP14A with identical electrical specifications, package dimensions, pinout, and thermal characteristics. Both share the same UL94V-0 epoxy case, 5 g mass, and Pin 1 cathode orientation. No PCB modifications or firmware updates are required when migrating to the MADA3KP14A, which incorporates updated RoHS-compliant (e3) marking and plating.
What IEC standards does the MADA3KP14A support for surge immunity testing?
The MADA3KP14A supports IEC61000-4-2 (ESD ±8 kV contact), IEC61000-4-4 (EFT ±4 kV), and IEC61000-4-5 (lightning surge up to Class 4 with 42 Ω source impedance). Its 3000 W rating and 23.2 V clamping enable compliance with these standards in single-stage protection configurations. Test validation is documented in Microsemi's RF01243 datasheet Rev B, Figures 1–3 and Table 1.
