Product details
Overview
MADA3KP16AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 16 V standoff voltage (VWM), 17.8–19.7 V breakdown range (V(BR)), and 26.0 V maximum clamping voltage (VC) at 115.4 A peak pulse current. It provides secondary lightning protection per IEC61000-4-5 (42 Ω, Class 1–4), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in telecom power interfaces.
For engineers reviewing the MADA3KP16AE3 datasheet, MADA3KP16AE3 pinout, MADA3KP16AE3 application, or MADA3KP16AE3 equivalent, key selection criteria include its 16 V working voltage, 26.0 V clamping performance at 115.4 A, RoHS-compliant e3 marking, unidirectional polarity, and MIL-PRF-19500 screening readiness for high-reliability aerospace and industrial systems.
Technical Context
The MADA3KP16AE3 operates as a silicon avalanche diode-based TVS array optimized for fast transient suppression in DC power rails and signal lines. Its sub-100 ps response time enables effective ESD protection, while its 10/1000 µs waveform-rated 3000 W peak pulse power supports robust surge handling in harsh environments.
Designed for surface-mount vertical mounting, it features tin-lead or matte-tin terminations compliant with MIL-STD-750 Method 2026, UL94V-0 void-free epoxy packaging, and polarity defined by dot-marked Pin 1 (cathode). Standby leakage is limited to ≤2 µA at 16 V, ensuring minimal system power loss during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 17.8–19.7 V @ 1 mA - Ensures reliable avalanche turn-on above operating voltage with controlled tolerance |
| VC @ IPP | 26.0 V @ 115.4 A - Clamping voltage during 10/1000 µs surge; defines maximum stress on protected circuit |
| PPP | 3000 W @ 10/1000 µs - Peak surge energy absorption capability under standardized lightning surge waveform |
| ID @ VWM | ≤2 µA - Ultra-low leakage preserves battery life and avoids false triggering in low-power systems |

Use Value: MIL-PRF-19500 upscreening option enables full lot traceability and wafer-level reliability data for regulatory submissions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Lower PPP (400 W), same VWM (16 V), SMA package (smaller footprint, lower thermal mass) | Not suitable for IEC61000-4-5 Class 4; limited to lower-energy ESD/EFT and switching transients | Select SMAJ16A only when surge energy is ≤400 W and PCB space is constrained. |
| 1.5KE16A | Higher IPP (125 A), same VC (26.0 V), axial-leaded DO-15 package (through-hole) | Requires manual or wave soldering; incompatible with automated SMT assembly and high-density layouts | Choose 1.5KE16A only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMAJ16A and 1.5KE16A, the MADA3KP16AE3 delivers 7.5× higher surge power handling in an SMT-optimized package with military-grade screening support-making it the sole choice for Class 4 lightning protection in automated production of telecom and industrial control systems.

FAQ
What is the clamping voltage of the MADA3KP16AE3 under a 10/1000 µs surge?
The MADA3KP16AE3 has a maximum clamping voltage (VC) of 26.0 V at 115.4 A peak pulse current under the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during surge events. The MADA3KP16AE3 achieves this performance using silicon avalanche diode technology with tightly controlled breakdown characteristics.
Is the MADA3KP16AE3 RoHS-compliant?
Yes, the MADA3KP16AE3 is RoHS-compliant, as indicated by the "e3" suffix in its part number. This denotes annealed matte-tin termination plating and adherence to Directive 2011/65/EU. The device meets JEDEC J-STD-020B moisture sensitivity Level 1, eliminating dry-pack requirements and enabling use in standard SMT reflow profiles without preconditioning.
Does the MADA3KP16AE3 support MIL-PRF-19500 screening?
Yes, the MADA3KP16AE3 supports optional upscreening per MIL-PRF-19500, including wafer fabrication and assembly lot traceability, 3σ lot norm screening on standby current (ID), and conformance inspections. This makes the MADA3KP16AE3 suitable for high-reliability applications in aerospace, defense, and critical infrastructure where component pedigree and long-term stability are mandatory.
What is the polarity configuration of the MADA3KP16AE3?
The MADA3KP16AE3 is a unidirectional TVS device, with Pin 1 designated as the cathode (marked by a dot on the package top) and Pin 2 as the anode. This configuration allows it to block 16 V in the forward direction while clamping positive transients on the cathode side to ground-ideal for protecting DC power rails where reverse voltage is not expected.
How does the MADA3KP16AE3 compare to bidirectional TVS devices like MADA3KP16CE3?
The MADA3KP16AE3 differs from bidirectional variants such as MADA3KP16CE3 by offering unidirectional conduction-blocking only positive overvoltages relative to ground. Bidirectional versions protect both polarities but exhibit higher capacitance and reduced clamping efficiency for DC applications. The MADA3KP16AE3 is preferred for 12–24 V DC systems where polarity is fixed and lowest possible clamping voltage is critical.
