Product details
Overview
MDA3KP6.0A 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 6.0 V reverse standoff voltage (VWM), 6.67–7.37 V breakdown voltage (V(BR)), 10.3 V maximum clamping voltage at 291.3 A peak pulse current, and operates from −55 °C to +150 °C - deployed in industrial motor drives, telecom power supplies, and automotive ECUs.
For engineers reviewing the MDA3KP6.0A datasheet, MDA3KP6.0A pinout, MDA3KP6.0A application, or MDA3KP6.0A equivalent, key selection criteria include clamping performance under 10/1000 µs surge, standoff voltage margin versus system operating voltage, thermal derating above 25 °C, and compliance with IEC61000-4-2/4-4/4-5 for ESD, EFT, and secondary lightning protection.
Technical Context
The MDA3KP6.0A uses an avalanche diode structure optimized for sub-100 ps response time in unidirectional configuration, enabling suppression of fast transients before downstream ICs are damaged. Its 3000 W peak pulse power rating is validated per 10/1000 µs waveform with ≤0.05% duty factor, and it maintains <10.3 V clamping up to 291.3 A IPP.
Designed for surface-mount reliability, the device meets MIL-PRF-19500 screening options and exhibits Level 1 moisture sensitivity (IPC/JEDEC J-STD-020B), eliminating dry-pack requirements. Polarity is defined by dot-marked Pin 1 as cathode, consistent across the MDA3KPxxA family.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous DC or peak AC voltage the device blocks without conduction. |
| V(BR) min–max | 6.67–7.37 V @ I(BR) = 10 mA - Ensures reliable avalanche initiation above system operating voltage with margin. |
| VC @ IPP | 10.3 V @ 291.3 A - Clamping voltage during worst-case 10/1000 µs surge; defines maximum stress on protected circuitry. |
| ID @ VWM | 1000 µA - Low leakage ensures minimal power loss and no false triggering in standby. |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy surges typical of inductive switching and lightning-induced transients. |
| TJ range | −55 °C to +150 °C - Supports operation in harsh environments including engine compartments and industrial enclosures. |
Pinout & Package
MDA3KP6.0A is housed in a void-free thermosetting epoxy package (UL94V-0 rated) with tin-lead or matte-tin plating, weighing ~5 g. Pin 1 is cathode, marked by a dot on top of the body; polarity follows odd-pin cathode convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; conducts surge current to ground when V > V(BR). |
| Pin 2 | Anode | Typically tied to system ground or low-impedance return path for unidirectional clamping. |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables robust protection against high-energy transients such as 42 Ω IEC61000-4-5 Class 4 lightning surges. |
| Sub-100 ps response time | Clamps ESD events (IEC61000-4-2) before sensitive logic or analog inputs are overstressed. |
| MIL-PRF-19500 screening option | Supports high-reliability programs requiring wafer lot traceability and 3σ ID screening. |
| Level 1 moisture sensitivity | Eliminates bake-out requirement prior to reflow, reducing assembly cost and risk of delamination. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A | 600 W PPP rating, same VWM and V(BR) range, but lower IPP (96.4 A) and higher VC (10.5 V). | Suitable for lower-energy environments (e.g., consumer USB ports); not rated for IEC61000-4-5 Class 4. | Select MDA3KP6.0A where 3000 W surge immunity is required; SMBJ6.0A only if space or cost constraints dominate and energy levels are <1 kA. |
| SMCJ6.0A | 1500 W PPP, same VWM, V(BR), and VC (10.3 V), but lower thermal mass and derating above 75 °C. | Valid for IEC61000-4-5 Class 2–3 (42 Ω/12 Ω), but insufficient for sustained Class 4 testing. | Choose MDA3KP6.0A for mission-critical industrial or automotive use; SMCJ6.0A for cost-sensitive, medium-energy applications with ambient <75 °C. |
Compared with SMBJ6.0A and SMCJ6.0A, the MDA3KP6.0A delivers triple the peak pulse power and superior thermal robustness, making it the only choice among the three for full IEC61000-4-5 Class 4 compliance and high-reliability screening programs.

FAQ
What is the clamping voltage of MDA3KP6.0A at its rated peak pulse current?
The MDA3KP6.0A has a maximum clamping voltage (VC) of 10.3 V at its rated peak pulse current (IPP) of 291.3 A under 10/1000 µs waveform conditions. This value is measured per standard test methods and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MDA3KP6.0A maintains this clamping performance across its full operating temperature range when derated per Figure 3 in the datasheet.
Is MDA3KP6.0A RoHS compliant?
Yes, MDA3KP6.0A is RoHS compliant, indicated by the "e3" suffix in its full marking per the part nomenclature on page 2 of RF01243 Rev B. The device uses annealed matte-tin plating on terminals and conforms to Directive 2011/65/EU. RoHS compliance applies to both standard and MIL-PRF-19500 screened versions unless otherwise specified in custom order documentation.
Can MDA3KP6.0A be used for bidirectional transient protection?
No, MDA3KP6.0A is unidirectional only. Bidirectional variants are designated with a "C" suffix (e.g., MDA3KP6.0CA). The MDA3KP6.0A conducts only for positive transients relative to its cathode (Pin 1); reverse polarity surges will not be clamped. For AC-coupled or bipolar signal lines, MDA3KP6.0CA must be selected instead.
What is the standoff voltage rating of MDA3KP6.0A and how should it be applied in circuit design?
The MDA3KP6.0A has a rated reverse standoff voltage (VWM) of 6.0 V - the maximum continuous DC or peak AC voltage it blocks without significant leakage. In circuit design, VWM must be ≥1.1× the maximum normal operating voltage of the protected line to avoid false triggering. For example, it is appropriate for 5 V logic rails but not for 12 V systems without derating or supplemental protection.
Does MDA3KP6.0A require special handling or baking before reflow soldering?
No, MDA3KP6.0A does not require baking prior to reflow. It is rated at IPC/JEDEC J-STD-020B Level 1 moisture sensitivity, meaning it may be stored indefinitely at ≤30 °C/60% RH and placed directly into standard lead-free reflow profiles (peak 260 °C for 10 s) without preconditioning. This eliminates process steps and reduces risk of popcorn cracking during assembly.
