Product details
Overview
MXDA3KP6.0A 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 across –55 °C to +150 °C junction temperature.
For engineers reviewing the MXDA3KP6.0A datasheet, MXDA3KP6.0A pinout, MXDA3KP6.0A application, or MXDA3KP6.0A equivalent, this device is selected for secondary lightning protection per IEC 61000-4-5 (42 Ω, Class 1–4), ESD/EFT suppression per IEC 61000-4-2/4-4, and inductive switching transient mitigation in industrial power interfaces.
Technical Context
The MXDA3KP6.0A is a single-channel unidirectional TVS diode optimized for fast clamping response (<100 ps rise time) and high-energy surge handling under 10/1000 µs waveform conditions. Its design targets low clamping ratio (VC/VWM ≈ 1.72) and tight V(BR) tolerance (±5%) to ensure predictable turn-on behavior during transients.
It complies with MIL-PRF-19500 screening options for high-reliability applications and uses void-free UL94V-0 epoxy packaging with tin-lead or matte-tin terminations. Polarity is defined by dot marking; Pin 1 is cathode, consistent with standard TVS orientation for DC rail protection.
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 @ 10 mA - Confirmed breakdown threshold range ensuring reliable triggering above operating rail |
| VC @ IPP | 10.3 V @ 291.3 A - Clamping voltage limiting downstream component stress during 3 kW surge events |
| PPP | 3000 W @ 10/1000 µs - Peak pulse power rating defining maximum transient energy absorption capability |
| ID @ VWM | 1000 µA max - Low leakage current preserving system efficiency and minimizing standby power loss |
| TJ range | –55 °C to +150 °C - Extended thermal operating envelope supporting under-hood, industrial, and aerospace environments |
Pinout & Package
MXDA3KP6.0A is housed in a molded plastic DO-214AB (SMC) package with two terminals: anode and cathode. The package measures 21.03 × 6.86 × 8.64 mm (L × W × H), features a polarity dot marking on top indicating Pin 1 (cathode), and uses tin-lead or matte-tin plating compliant with MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (marked) | Cathode | Connected to protected line's positive rail; conducts when transient exceeds V(BR), shunting current to ground |
| Pin 2 | Anode | Connected to system ground reference; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables robust protection against IEC 61000-4-5 Class 4 surges (42 Ω source) without derating at 25 °C |
| Clamping voltage ≤10.3 V | Ensures downstream ICs rated for 12 V logic rails remain within safe operating limits during 291 A transients |
| Breakdown tolerance ±5% | Guarantees consistent turn-on timing across production lots, critical for deterministic system-level surge response |
| MIL-PRF-19500 screening option | Supports high-reliability qualification for defense, avionics, and mission-critical industrial control systems |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|
Use Scenario: Protection of 24 V DC input stages in variable-frequency drives against inductive kickback and grid coupling transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between DC+ and chassis ground to clamp positive-going surges before they reach gate drivers or MCU power supplies.

IC Role / Device Role / Timing Role: Cathode tied to -48 V rail, anode to ground; clamps negative transients exceeding V(BR) while blocking normal operating voltage. Use Value: Withstands 291 A peak pulses per IEC 61000-4-5 (12 Ω source, Class 3), maintaining uninterrupted service during outdoor cabinet surges. |
| Automotive Body Control Modules | Medical Imaging Power Supplies |
Use Scenario: Input protection for 12 V battery-fed ECUs subjected to load dump and ISO 7637-2 Pulse 5a/b transients. IC Role / Device Role / Timing Role: Primary TVS on main power entry point, coordinated with upstream fuses and secondary LC filtering.

IC Role / Device Role / Timing Role: Mounted directly at converter input terminals to absorb repetitive switching transients and ESD events from operator interface panels. Use Value: Maintains ≤1000 µA leakage at 6 V, avoiding drift in precision analog sensing circuits powered from same supply rail. |
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 | Lower PPP (600 W), same VWM and V(BR) range, SMB package (smaller footprint, lower thermal mass) | Not suitable for IEC 61000-4-5 Class 4; limited to Class 2/3 or ESD/EFT-only use cases | Select when board space is constrained and surge energy is ≤600 W |
| 1.5KE6.8A | Higher V(BR) (7.56–8.36 V), same PPP (3000 W), axial leaded DO-201 package (through-hole mounting) | Requires PCB rework for SMT-to-through-hole transition; not compatible with automated assembly | Select only for legacy through-hole designs where requalification of SMT process is impractical |
Compared with SMBJ6.0A and 1.5KE6.8A, MXDA3KP6.0A delivers higher surge margin in compact SMT form with verified MIL-PRF-19500 screening support-making it optimal for new industrial and automotive designs requiring Class 4 immunity and long-term supply stability.

FAQ
What is the clamping voltage specification for MXDA3KP6.0A under full-rated surge conditions?
The MXDA3KP6.0A has a maximum clamping voltage (VC) of 10.3 V at its peak pulse current (IPP) of 291.3 A, measured under standardized 10/1000 µs waveform conditions. This value ensures that protected circuitry sees no more than 10.3 V during a full 3000 W transient event, making MXDA3KP6.0A suitable for safeguarding 12 V logic rails and sensitive analog front-ends.
Is MXDA3KP6.0A RoHS-compliant, and what does the 'e3' suffix indicate?
Yes, MXDA3KP6.0A is RoHS-compliant, as confirmed by the 'e3' marking in its part number nomenclature per Microsemi documentation. The 'e3' suffix denotes annealed matte-tin termination plating meeting JEDEC J-STD-020B Level 1 moisture sensitivity requirements-no dry pack needed-and full compliance with EU Directive 2011/65/EU.
How does MXDA3KP6.0A differ from bidirectional variants like MXDA3KP6.0CA?
MXDA3KP6.0A is unidirectional and protects against positive transients only (cathode to anode conduction), whereas MXDA3KP6.0CA is bidirectional and clamps both polarities. The unidirectional MXDA3KP6.0A offers lower leakage (1000 µA vs. 10 µA for bidirectional at same VWM) and is preferred for DC power rail protection where polarity is fixed and reverse conduction must be avoided.
Can MXDA3KP6.0A be used for IEC 61000-4-5 Class 4 testing with 42 Ω source impedance?
Yes, MXDA3KP6.0A is explicitly rated for IEC 61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as documented in the Applications/Benefits section of RF01243 Rev B. Its 3000 W PPP rating and 291.3 A IPP capability meet the 4 kV test level requirement under this configuration.
What is the thermal derating behavior of MXDA3KP6.0A above 25 °C ambient?
MXDA3KP6.0A follows a linear derating curve starting at 25 °C, with peak pulse power decreasing to ~50% of rated 3000 W at +125 °C junction temperature, as shown in Figure 3 of RF01243 Rev B. Designers must apply appropriate thermal relief and consider junction-to-ambient resistance to maintain safe operation in high-temperature enclosures.
