Product details
Overview
MXDA3KP16A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability overvoltage protection in power rails and signal lines. It features a 16 V reverse standoff voltage (VWM), 17.8–19.7 V breakdown voltage (V(BR)), 26.0 V maximum clamping voltage at 115.4 A peak pulse current, and operates from −55 °C to +150 °C - deployed in industrial motor drives for IGBT gate protection against switching transients.
For engineers reviewing the MXDA3KP16A datasheet, MXDA3KP16A pinout, MXDA3KP16A application, or MXDA3KP16A equivalent, key selection criteria include clamping performance under 10/1000 µs surge, standoff voltage margin relative to DC bus voltage, thermal derating above 25 °C, and compliance with IEC61000-4-5 secondary lightning testing at 42 Ω, 12 Ω, and 2 Ω source impedances.
Technical Context
The MXDA3KP16A implements a silicon avalanche diode structure optimized for sub-100 ps response time and low dynamic impedance during 3000 W transient events. Its unidirectional polarity defines cathode-anode conduction behavior, with odd-numbered pins serving as cathodes per package marking convention.
It is rated for 1000 µA standby current at 16 V VWM and undergoes full lot surge testing per 10/1000 µs waveform. Derating follows a defined curve down to 0% power at 150 °C junction temperature, supporting operation in thermally constrained enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous DC or peak AC voltage the device blocks without clamping |
| V(BR) min/max | 17.8–19.7 V @ 1 mA - ensures reliable avalanche initiation before system damage threshold |
| VC @ IPP | 26.0 V @ 115.4 A - limits downstream voltage stress during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - supports robust protection against lightning-induced surges and inductive kickback |
| ID @ VWM | 2 µA - negligible leakage at operating voltage, avoiding power loss or false triggering |
| TJ/TSTG | −55 to +150 °C - enables deployment in automotive engine bays and industrial control cabinets |
| Response time | <100 ps - clamps before most semiconductor failure mechanisms initiate |
Pinout & Package
MXDA3KP16A uses a 3-pin SMD package (case outline per RF01243, Page 6) with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity indicated by dot marking for Pin 1. Odd-numbered pins are cathodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connected to protected line; conducts when line voltage exceeds V(BR) relative to ground |
| Pin 2 | Anode (common) | Shared anode node tied to system ground or reference plane |
| Pin 3 | Cathode of Channel 2 | Second independent protection path - enables dual-rail or differential line protection |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Supports IEC61000-4-5 Class 4 lightning immunity with 42 Ω source impedance |
| Unidirectional construction | Prevents reverse-bias leakage on DC-coupled lines while enabling precise clamping directionality |
| MIL-PRF-19500 upscreening option | Enables qualification for aerospace and defense systems requiring wafer lot traceability and 3σ ID screening |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing overhead |
| Clamping voltage ≤26.0 V | Protects 24 V nominal systems (e.g., PLC I/O modules) within safe IC input voltage limits |
Applications
| Industrial Motor Drives | Programmable Logic 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 |
|---|---|---|---|
| SMBJ16A | 600 W PPP rating, same VWM and VC, but lower IPP (32.4 A) and smaller SMB package | Not suitable for IEC61000-4-5 Class 4; limited to Class 2/3 in 42 Ω tests | Select SMBJ16A only for space-constrained, lower-energy environments where 3000 W headroom is unnecessary |
| SMCJ16A | 1500 W PPP, same VWM, VC = 26.0 V, IPP = 57.7 A, DO-214AB package | Meets IEC61000-4-5 Class 3 at 42 Ω but fails Class 4; lower thermal mass than MDA series | Choose SMCJ16A for cost-sensitive industrial designs where full 3000 W capability is not mandated |
Compared with SMBJ16A and SMCJ16A, MXDA3KP16A delivers double the pulse power handling and verified Class 4 lightning immunity - critical for mission-critical infrastructure where single-event survivability must exceed 3 kA surge currents.

FAQ
What is the clamping voltage of MXDA3KP16A at its rated peak pulse current?
The MXDA3KP16A has a maximum clamping voltage (VC) of 26.0 V at its rated peak pulse current (IPP) of 115.4 A under 10/1000 µs waveform conditions. This value is measured across the device terminals during surge testing and defines the upper voltage limit imposed on protected circuitry. The MXDA3KP16A maintains this clamping performance consistently across its qualified temperature range and after multiple surge events, as verified by full-lot surge testing per the datasheet.
Is MXDA3KP16A RoHS compliant?
Yes, MXDA3KP16A is RoHS compliant, indicated by the "e3" suffix in its full part marking per Microsemi's nomenclature guide. The device uses annealed matte-tin or tin-lead plating compatible with standard reflow profiles and meets lead-free soldering requirements per J-STD-020B. RoHS compliance applies to all standard production lots unless otherwise specified in custom ordering documentation for MXDA3KP16A.
How does the polarity marking work on MXDA3KP16A?
MXDA3KP16A uses a dot marking on the top of the package to identify Pin 1, and per the datasheet, odd-numbered pins (Pin 1 and Pin 3) are cathodes. Pin 2 is the common anode. This unidirectional configuration means current flows from anode (Pin 2) to cathode (Pin 1 or Pin 3) during clamping. The polarity marking ensures correct orientation during PCB layout - reversing the device would prevent proper transient suppression in DC-coupled applications.
Can MXDA3KP16A be used for bidirectional protection?
No, MXDA3KP16A is unidirectional only. Bidirectional variants in the same family carry a "C" suffix (e.g., MDA3KP16CA). The MXDA3KP16A conducts only when the cathode-side voltage exceeds the anode-side voltage by ≥V(BR); it blocks reverse voltage beyond VWM but does not clamp negative transients. For AC or differential-line protection requiring symmetrical clamping, the MXDA3KP16A must be paired with a second device or replaced with a certified bidirectional part.
What is the maximum operating temperature for MXDA3KP16A?
The MXDA3KP16A has a maximum junction and storage temperature of +150 °C, with derated pulse power beginning above 25 °C per Figure 3 in the datasheet. At 100 °C ambient, its 3000 W peak pulse power is reduced to approximately 60% of rated value. This high-temperature capability allows MXDA3KP16A to operate reliably in sealed industrial enclosures or near heat-generating power stages without thermal shutdown or parameter drift.
