Product details
Overview
MADA3KP14CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, featuring 14 V standoff voltage (VWM), 15.6–17.2 V breakdown voltage (V(BR)), 23.2 V max clamping voltage at 129.4 A peak pulse current, and -55°C to +150°C operating junction temperature - deployed for secondary lightning protection in telecom power interfaces.
For engineers reviewing the MADA3KP14CAE3 datasheet, MADA3KP14CAE3 pinout, MADA3KP14CAE3 application, or MADA3KP14CAE3 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 matte-tin plating, and 100 ps response time under zero-bias conditions.
Technical Context
The MADA3KP14CAE3 implements a silicon avalanche diode structure optimized for fast clamping of high-energy transients. Its bidirectional configuration enables symmetrical surge suppression across AC lines or differential signal paths without polarity constraints.
It delivers 3000 W peak pulse power at 10/1000 µs waveform, with clamping performance validated up to 129.4 A IPP and thermal derating per Figure 3 down to 0% power at +150°C junction temperature. Standby leakage ID is ≤2 µA at 14 V VWM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 14 V - maximum continuous reverse working voltage before clamping initiates |
| V(BR) min/max | 15.6–17.2 V @ 1 mA - ensures reliable avalanche conduction onset within defined tolerance |
| VC @ IPP | 23.2 V @ 129.4 A - limits downstream voltage stress during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - sustains high-energy lightning-induced surges per IEC61000-4-5 |
| TJ range | -55°C to +150°C - supports operation in harsh industrial and outdoor environments |
| ID @ VWM | ≤2 µA - negligible standby power loss and minimal impact on high-impedance circuits |
| Response time | <100 ps - clamps ESD events before sensitive ICs experience damage |
Pinout & Package
Package: DO-214AB (SMC) - surface-mount, void-free thermosetting epoxy body meeting UL94V-0; dimensions: 21.03 × 6.86 × 8.64 mm (L × W × H); polarity marked with dot indicating Pin 1 (cathode for unidirectional variant; symmetric terminals for bidirectional MADA3KP14CAE3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (Terminal A) | One side of bidirectional avalanche junction; connects to line or signal path requiring symmetrical protection |
| Pin 2 | Cathode (Terminal K) | Opposite side of bidirectional junction; completes low-impedance clamp path during either polarity surge |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection of AC lines or differential buses without external polarity management |
| IEC61000-4-5 Class 1–4 compliance | Validated for secondary lightning protection with 42 Ω, 12 Ω, and 2 Ω source impedances per specification |
| RoHS-compliant matte-tin plating | Ensures solderability per MIL-STD-750 Method 2026 and eliminates lead-based process risks |
| 3σ lot norm screening on ID | Guarantees ≤2 µA leakage across production lots for predictable high-impedance interface behavior |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life constraints per IPC/JEDEC J-STD-020B |
Applications
| Telecom AC Power Input | Industrial Ethernet PHY Interface |
|---|---|
Use Scenario: Protection of AC/DC front-end rectifiers and PFC stages against utility-side surges and induced lightning transients. IC Role / Device Role / Timing Role: Primary TVS clamp placed upstream of bridge rectifier to shunt >1 kV surges before reaching bulk capacitors and controllers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ14CA | 600 W PPP rating, SMA package, 23.2 V VC @ 26.1 A IPP | Lower energy handling; suitable only for ESD/EFT, not IEC61000-4-5 Class 4 | Select when board space is constrained and surge threat level is limited to IEC61000-4-2/4 |
| Vishay VMM14C | 3000 W PPP, DO-214AB, but unidirectional; requires dual placement for AC protection | Not inherently bidirectional - needs two devices for symmetrical line protection | Choose only if existing layout uses unidirectional TVS and polarity is fixed |
Compared with MADA3KP14CAE3, SMAJ14CA offers smaller footprint but insufficient energy capacity for lightning-level threats, while VMM14C matches power rating but lacks integrated bidirectionality - requiring additional components and PCB area to achieve equivalent protection function.

FAQ
What is the clamping voltage of MADA3KP14CAE3 at its rated peak pulse current?
The MADA3KP14CAE3 has a maximum clamping voltage (VC) of 23.2 V at its peak pulse current (IPP) of 129.4 A under 10/1000 µs waveform conditions. This value is measured across the device terminals during standardized surge testing and defines the upper voltage limit imposed on protected circuitry during worst-case transients. The MADA3KP14CAE3 maintains this clamping performance consistently across its qualified temperature range.
Is MADA3KP14CAE3 compliant with IEC61000-4-5 for secondary lightning protection?
Yes, MADA3KP14CAE3 is validated for IEC61000-4-5 secondary lightning protection across Class 1–4 with 42 Ω, 12 Ω, and 2 Ω source impedances. Its 3000 W peak pulse power rating and 23.2 V clamping voltage enable it to meet the voltage and energy thresholds required for telecom and industrial equipment subjected to coupled lightning surges. The MADA3KP14CAE3 data sheet explicitly lists these classifications in the Applications section.
What does the "C" suffix in MADA3KP14CAE3 indicate?
The "C" suffix in MADA3KP14CAE3 denotes bidirectional polarity - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions without requiring orientation-specific placement. This differs from unidirectional variants (e.g., MADA3KP14AE3), which conduct only in reverse bias. The MADA3KP14CAE3 achieves this via back-to-back avalanche diode configuration within a single DO-214AB package.
What is the maximum operating temperature for MADA3KP14CAE3?
The MADA3KP14CAE3 has a maximum junction temperature (TJ) of +150°C and a storage temperature range of -55°C to +150°C. Its thermal derating curve (Figure 3 in the datasheet) shows linear reduction of peak pulse power from 100% at 25°C to 0% at 150°C, ensuring safe operation in high-ambient environments such as enclosed base stations or industrial control cabinets. The MADA3KP14CAE3 remains fully functional throughout this full range.
Does MADA3KP14CAE3 require dry packing or special handling due to moisture sensitivity?
No, MADA3KP14CAE3 has IPC/JEDEC J-STD-020B moisture sensitivity level (MSL) 1, meaning it is not moisture-sensitive and requires no dry pack, baking, or floor-life controls prior to reflow soldering. Its void-free thermosetting epoxy body and matte-tin plating contribute to this robustness. This simplifies manufacturing logistics and eliminates yield risk from popcorning during assembly - a key advantage of the MADA3KP14CAE3 in high-volume production.
