Product details
Overview
MXDA3KP6.5CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, designed for high-reliability secondary lightning and ESD protection. It features a 6.5 V standoff voltage (VWM), 7.22–7.98 V breakdown range (V(BR)), 11.2 V clamping voltage at 267.9 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MXDA3KP6.5CA datasheet, MXDA3KP6.5CA pinout, MXDA3KP6.5CA application, or MXDA3KP6.5CA equivalent, key selection criteria include IEC61000-4-5 Class 1–4 compliance with 12 Ω/42 Ω source impedance, bidirectional polarity, RoHS-compliant matte-tin plating, and 100 ps response time - all critical for industrial power input, telecom line interface, and automotive body electronics surge hardening.
Technical Context
The MXDA3KP6.5CA is a silicon avalanche diode-based TVS array optimized for fast-clamp transient suppression in bidirectional signal and power lines. Its structure enables symmetrical clamping in both polarities, with sub-100 ps response and guaranteed clamping at ≤11.2 V under 267.9 A (10/1000 µs waveform).
It meets MIL-PRF-19500 screening options for high-reliability applications and supports IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and IEC61000-4-5 (lightning) across multiple source impedances - specifically Class 1–3 with 12 Ω and Class 1–4 with 42 Ω source impedance per test standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous operating voltage before clamping begins |
| V(BR) min–max | 7.22–7.98 V @ 10 mA - ensures reliable avalanche initiation across temperature and lot variation |
| VC @ IPP | 11.2 V @ 267.9 A - limits downstream voltage stress during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - sustains high-energy transients without failure |
| ID @ VWM | 500 µA max - low leakage preserves system standby power integrity |
| TJ/TSTG | –55 °C to +150 °C - supports under-hood, industrial, and aerospace thermal environments |
| Response Time | <100 ps - clamps before sensitive ICs experience overvoltage damage |
Pinout & Package
MXDA3KP6.5CA uses a DO-214AB (SMC) surface-mount package with two terminals: Pin 1 (cathode) and Pin 2 (anode), configured as a bidirectional pair. Polarity is marked by a dot on the package top indicating Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |

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 PPP rating, same VWM and bidirectional configuration, SMB package (smaller footprint) | Lower energy handling - suitable only for ESD/EFT, not secondary lightning | Select when board space is constrained and surge threat level is limited to IEC61000-4-2/4-4 only |
| 1.5KE6.8CA | 1500 W PPP, axial-leaded DO-201 package, higher clamping voltage (11.5 V) | Through-hole mounting required; less suitable for automated SMT assembly | Choose for legacy designs or cost-sensitive non-SMT production where 1500 W suffices |
Compared with SMBJ6.5CA and 1.5KE6.8CA, MXDA3KP6.5CA delivers double the surge energy capacity of the SMBJ and 2× the power rating of the 1.5KE, while maintaining SMT compatibility and tighter clamping - making it the only choice for new designs requiring full IEC61000-4-5 Class 4 compliance in compact form factor.

FAQ
What is the clamping voltage of MXDA3KP6.5CA at its rated peak pulse current?
The MXDA3KP6.5CA 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 per IEC61000-4-5 test methodology and guarantees that downstream circuitry remains below destructive voltage thresholds during high-energy transients. The MXDA3KP6.5CA maintains this clamping performance across its full operating temperature range.
Is MXDA3KP6.5CA RoHS compliant and what plating does it use?
Yes, MXDA3KP6.5CA is RoHS compliant, indicated by the "e3" suffix in its full part marking. It uses annealed matte-tin plating on its terminals, which ensures reliable solderability per MIL-STD-750 Method 2026 and compatibility with both tin-lead and lead-free reflow profiles. The MXDA3KP6.5CA's plating also supports high-reliability screening per MIL-PRF-19500 requirements.
Does MXDA3KP6.5CA support IEC61000-4-5 Class 4 testing?
Yes, MXDA3KP6.5CA is validated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance. It is also rated for Class 1–3 with 12 Ω source impedance and Class 2–4 with 2 Ω source impedance depending on voltage grade. The MXDA3KP6.5CA's 3000 W peak pulse power rating directly supports these test levels without derating at 25 °C.
What is the standoff voltage and breakdown range of MXDA3KP6.5CA?
The MXDA3KP6.5CA has a rated reverse standoff voltage (VWM) of 6.5 V and a minimum-to-maximum breakdown voltage (V(BR)) range of 7.22 V to 7.98 V at 10 mA test current. This ensures robust margin between normal operating voltage and avalanche onset, minimizing false triggering while guaranteeing reliable clamping onset during transients. The MXDA3KP6.5CA's tight V(BR) tolerance supports consistent system-level protection design.
What package type and pin configuration does MXDA3KP6.5CA use?
MXDA3KP6.5CA uses the DO-214AB (SMC) surface-mount package with two terminals: Pin 1 (cathode) and Pin 2 (anode), arranged as a bidirectional pair. A dot on the package top identifies Pin 1. The MXDA3KP6.5CA's mechanical dimensions conform to JEDEC outline SMC, with body size 21.03 × 8.64 × 2.67 mm (L × W × H), enabling high-power density placement in space-constrained layouts.
