Product details
Overview
MXDA3KP6.5CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, featuring 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 - designed for secondary lightning protection in telecom power interfaces.
For engineers reviewing the MXDA3KP6.5CAE3 datasheet, MXDA3KP6.5CAE3 pinout, MXDA3KP6.5CAE3 application, or MXDA3KP6.5CAE3 equivalent, key selection criteria include bidirectional polarity, IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω source impedance, RoHS-compliant matte-tin plating, and 100 ps response time under zero-bias conditions.
Technical Context
This TVS array uses silicon avalanche diode technology to clamp transient overvoltages before they damage downstream circuitry. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal lines, and it meets IEC61000-4-5 surge immunity requirements across multiple source impedances (2 Ω, 12 Ω, 42 Ω).
The device operates within –55 °C to +150 °C junction temperature range and delivers 3000 W peak pulse power at 10/1000 µs waveform. It is surge-tested per unit, has Level 1 moisture sensitivity (no dry pack required), and supports high-reliability screening per MIL-PRF-19500 upon request.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse operating voltage before clamping begins |
| V(BR) min–max | 7.22–7.98 V @ 10 mA - ensures reliable avalanche initiation across process variation |
| VC @ IPP | 11.2 V @ 267.9 A - limits voltage seen by protected ICs during worst-case 10/1000 µs surge |
| IPP | 267.9 A - peak surge current capability matching IEC61000-4-5 Class 4 with 42 Ω source |
| TJ range | –55 °C to +150 °C - supports operation in industrial and outdoor telecom enclosures |
| Response time | <100 ps - clamps ESD events before logic-level devices experience latch-up |
| Moisture level | IPC/JEDEC J-STD-020B Level 1 - no bake-out required prior to reflow soldering |
Pinout & Package
MXDA3KP6.5CAE3 is housed in a DO-214AB (SMC) plastic package with void-free UL94V-0 epoxy body, matte-tin plated terminals, and polarity marked by a dot indicating Pin 1 (cathode for unidirectional variants; symmetric for bidirectional). Pin 1 and Pin 2 are electrically isolated anode/cathode pair terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (bidirectional) | One terminal of symmetrical avalanche junction; connects to line under protection |
| Pin 2 | Cathode (bidirectional) | Second terminal of symmetrical junction; connects to reference plane or return path |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5CA | 600 W rating (vs. 3000 W); same VWM/V(BR)/VC but lower IPP (94.7 A) | Suitable for board-level ESD/EFT only; not rated for IEC61000-4-5 Class 3/4 lightning | Select SMBJ6.5CA only when system-level surge testing is limited to ±8 kV contact ESD or 4 kV EFT. |
| 1.5KE6.8CA | Through-hole TO-218 package; 1500 W rating; higher VC (11.5 V) and lower IPP (131 A) | Requires PCB through-hole layout; lacks surface-mount thermal performance and moisture robustness | Choose 1.5KE6.8CA only if legacy through-hole assembly is mandated and 3000 W rating is not required. |
Compared with SMBJ6.5CA and 1.5KE6.8CA, MXDA3KP6.5CAE3 provides 5× higher surge power handling and DO-214AB thermal efficiency, making it uniquely suitable for telecom and industrial ports where IEC61000-4-5 Class 4 compliance is mandatory.

FAQ
What is the clamping voltage of MXDA3KP6.5CAE3 at its rated peak pulse current?
The MXDA3KP6.5CAE3 exhibits 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 standardized surge testing and defines the upper voltage limit imposed on protected circuitry during worst-case transients.
Is MXDA3KP6.5CAE3 compatible with lead-free reflow soldering processes?
Yes, MXDA3KP6.5CAE3 features annealed matte-tin plating compliant with MIL-STD-750 Method 2026 and supports peak reflow temperatures up to 260 °C for 10 seconds. Its e3 marking confirms RoHS compliance, and its Level 1 moisture sensitivity eliminates the need for pre-reflow baking.
Does MXDA3KP6.5CAE3 meet IEC61000-4-5 Class 4 surge immunity requirements?
Yes, MXDA3KP6.5CAE3 is rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance. The device sustains 267.9 A peak current at 11.2 V clamping, satisfying the 4 kV open-circuit voltage requirement for this class in telecom and industrial applications.
How does the bidirectional construction of MXDA3KP6.5CAE3 affect its circuit placement?
The bidirectional design of MXDA3KP6.5CAE3 allows symmetrical placement across any two nodes requiring transient suppression - such as differential data lines or AC-coupled power rails - without regard to polarity. Pin 1 and Pin 2 form a non-polarized junction, simplifying layout and eliminating orientation errors during automated assembly.
What is the maximum operating temperature range for MXDA3KP6.5CAE3?
MXDA3KP6.5CAE3 is specified for continuous operation from –55 °C to +150 °C junction temperature. This wide range supports deployment in uncontrolled environments such as outdoor telecom cabinets, motor control enclosures, and railway signaling equipment where ambient temperatures exceed standard commercial limits.
