Product details
Overview
MXDA3KP6.5A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 6.5 V standoff voltage (VWM), 7.22–7.98 V breakdown voltage (V(BR)), and 11.2 V clamping voltage (VC) at 267.9 A peak pulse current (IPP). It delivers sub-100 ps response time and is rated for secondary lightning protection per IEC61000-4-5 (42 Ω source) in Class 1–4 applications.
For engineers reviewing the MXDA3KP6.5A datasheet, MXDA3KP6.5A pinout, MXDA3KP6.5A application, or MXDA3KP6.5A equivalent, this device serves as a high-reliability, RoHS-compliant TVS for ESD/EFT/inductive switching surge suppression in telecom power interfaces, industrial I/O modules, and automotive body control units requiring stable 6.5 V operating margin.
Technical Context
The MXDA3KP6.5A operates as a silicon avalanche diode-based unidirectional TVS, designed to clamp transients before downstream circuitry exceeds safe voltage thresholds. Its 3000 W peak pulse power rating is validated at 10/1000 µs waveform, with clamping performance specified at 267.9 A IPP and 11.2 V VC.
It features a thermoset epoxy package meeting UL94V-0, tin-lead or matte-tin terminations compliant with MIL-STD-750 Method 2026, and polarity defined by odd-numbered pins as cathodes. Standby leakage is ≤500 µA at 6.5 V VWM, and junction temperature range spans –55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum continuous reverse operating voltage without conduction; sets minimum system overvoltage margin |
| V(BR) min/max | 7.22–7.98 V @ I(BR) - Confirmed avalanche onset range; ensures predictable turn-on above nominal rail |
| VC @ IPP | 11.2 V @ 267.9 A - Clamped voltage during worst-case 10/1000 µs surge; defines maximum stress on protected IC |
| PPP | 3000 W @ 10/1000 µs - Peak transient energy handling capacity; supports IEC61000-4-5 Class 4 compliance |
| ID @ VWM | ≤500 µA - Low standby leakage; avoids excessive quiescent power loss in battery-backed systems |
| Response time | <100 ps - Near-instantaneous avalanche reaction; effective against ESD (IEC61000-4-2) and EFT (IEC61000-4-4) |
Pinout & Package
MXDA3KP6.5A uses a 3-pin SMD package (case outline per RF01243, Page 6) with void-free UL94V-0 epoxy body, tin-lead or matte-tin terminations, 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 surge current to ground when voltage exceeds V(BR) |
| Pin 2 | Anode (common) | Shared low-impedance return path for all channels; must be routed to clean system ground |
| Pin 3 | Cathode of Channel 2 | Second independent protection channel; enables dual-line or differential-mode suppression |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables robust secondary lightning protection per IEC61000-4-5 up to Class 4 with 42 Ω source impedance |
| Sub-100 ps response time | Guarantees clamping before ESD events (±8 kV contact) propagate into sensitive logic or analog circuitry |
| RoHS-compliant e3 marking | Meets global environmental compliance requirements without lead-free reflow compatibility compromises |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to assembly per IPC/JEDEC J-STD-020B |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.5A | 600 W PPP rating, SMA package, 11.2 V VC @ 53.3 A IPP | Lower energy handling; suitable only for ESD/EFT, not Class 4 lightning | Select when board space is constrained and surge threat level is limited to IEC61000-4-2/4-4 |
| SMCJ6.5A | 1500 W PPP rating, SMC package, 11.2 V VC @ 134 A IPP | Half the energy capacity of MXDA3KP6.5A; insufficient for full IEC61000-4-5 Class 4 | Choose where cost sensitivity outweighs need for highest-level lightning immunity |
Compared with SMAJ6.5A and SMCJ6.5A, the MXDA3KP6.5A provides double the peak pulse power of SMCJ6.5A and five times that of SMAJ6.5A-enabling single-device compliance with IEC61000-4-5 Class 4 at 42 Ω source, where lower-rated alternatives require cascaded protection or derated application boundaries.

FAQ
What is the clamping voltage of MXDA3KP6.5A at its rated peak pulse current?
The MXDA3KP6.5A has a maximum clamping voltage (VC) of 11.2 V at its rated peak pulse current (IPP) of 267.9 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 during worst-case transients. The MXDA3KP6.5A maintains this clamping performance consistently across its operational temperature range.
Is MXDA3KP6.5A RoHS-compliant and what does the 'e3' marking indicate?
Yes, MXDA3KP6.5A is RoHS-compliant, as confirmed by the 'e3' suffix in its marking per Microsemi's nomenclature guide. The 'e3' designation specifies annealed matte-tin plating compliant with JEDEC standards and free of lead, cadmium, mercury, hexavalent chromium, PBB, and PBDE substances. This ensures environmental compliance without compromising solderability or thermal cycling reliability in lead-free reflow processes.
How does MXDA3KP6.5A differ from bidirectional variants like MXDA3KP6.5CA?
The MXDA3KP6.5A is unidirectional, meaning it conducts only in reverse bias above V(BR), with Pin 1 and Pin 3 as cathodes and Pin 2 as common anode. In contrast, MXDA3KP6.5CA is bidirectional and symmetrical-capable of clamping both positive and negative transients-making it suitable for AC lines or differential data paths. The MXDA3KP6.5A is selected where polarity is known and ground-referenced protection is required, such as DC power rails.
What is the maximum standoff voltage (VWM) and why is it critical for selecting MXDA3KP6.5A?
The maximum standoff voltage (VWM) of MXDA3KP6.5A is 6.5 V, representing the highest continuous reverse voltage the device can block without significant leakage. This parameter is critical because VWM must exceed the peak operating voltage of the protected line-e.g., a 5 V rail requires ≥5.5 V VWM-to avoid false triggering while ensuring headroom for ripple and tolerance. Selecting MXDA3KP6.5A for a 6.5 V system guarantees reliable blocking below 6.5 V and sharp clamping above ~7.2 V.
Does MXDA3KP6.5A require moisture-sensitive handling or baking before PCB assembly?
No, MXDA3KP6.5A is classified as Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ≤30 °C/60% RH without dry-pack desiccant or baking. This eliminates pre-reflow bake cycles and simplifies manufacturing logistics-particularly beneficial for high-mix, low-volume production of industrial and medical equipment where process overhead must be minimized. The MXDA3KP6.5A's epoxy body and termination system ensure robustness under standard SMT reflow profiles.
