Product details
Overview
MXLDA3KP6.5A 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 6.5 V reverse standoff voltage (VWM), 7.22–7.98 V breakdown voltage (V(BR)), 11.2 V maximum clamping voltage at 267.9 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MXLDA3KP6.5A datasheet, MXLDA3KP6.5A pinout, MXLDA3KP6.5A application, or MXLDA3KP6.5A equivalent, key selection criteria include IEC61000-4-2/4-4/4-5 compliance, 100 ps response time, RoHS-compliant e3 matte-tin plating, UL94V-0 molded package, and compatibility with secondary lightning protection Class 1–4 test configurations.
Technical Context
The MXLDA3KP6.5A is a single-channel unidirectional TVS diode optimized for fast clamping of high-energy transients. Its sub-100 ps response enables effective suppression of ESD (±30 kV contact), EFT (40 A), and 10/1000 µs lightning surges up to 3000 W. It uses silicon avalanche technology with controlled breakdown characteristics and is rated for surge testing per MIL-PRF-19500 screening options.
Designed for DC power rail and interface line protection, the device exhibits low leakage (<500 µA at VWM), tight V(BR) tolerance (±5%), and thermal stability supported by full lot traceability and 3σ screening on standby current (ID). Its vertical mounting orientation and void-free epoxy body ensure mechanical robustness in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum continuous working voltage before clamping begins; matches 5 V logic rails with margin. |
| V(BR) min–max | 7.22–7.98 V - Confirmed avalanche onset range at 10 mA; ensures reliable turn-on without premature conduction. |
| VC @ IPP | 11.2 V - Clamping voltage at 267.9 A peak pulse; limits downstream voltage stress during surge events. |

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 rating, SMA package, 10.5 V clamping at 62.2 A IPP | Limited to lower-energy ESD/EFT; not validated for IEC61000-4-5 Class 4 | Select when space-constrained layouts require SMT footprint smaller than MDA's vertical TO-277A variant. |
| SMCJ6.5A | 1500 W rating, SMC package, 11.2 V clamping at 133.9 A IPP | Mid-tier surge capacity; suitable for Class 2–3 lightning but not Class 4 with 2 Ω source | Choose where cost sensitivity outweighs need for full 3000 W headroom and MIL-PRF-19500 screening. |
Compared with SMAJ6.5A and SMCJ6.5A, the MXLDA3KP6.5A delivers double the peak pulse power and full Class 4 lightning validation, making it essential for mission-critical infrastructure where surge energy exceeds 1500 W and reliability screening is mandated.

FAQ
What is the clamping voltage of the MXLDA3KP6.5A at its rated peak pulse current?
The MXLDA3KP6.5A 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 per standard TVS test methodology and guarantees that protected circuitry will not experience voltages exceeding 11.2 V during worst-case surge events, ensuring compatibility with 5 V logic interfaces and sensitive analog front-ends.
Is the MXLDA3KP6.5A RoHS compliant and what does the 'e3' marking indicate?
Yes, the MXLDA3KP6.5A is RoHS compliant, indicated by the 'e3' suffix in its marking per Microsemi's nomenclature. The 'e3' designation specifies annealed matte-tin plating meeting JEDEC J-STD-020B Level 1 moisture sensitivity, eliminating dry-pack requirements and supporting Pb-free reflow profiles up to 260 °C for 10 seconds. This ensures environmental compliance without compromising solderability or reliability.
Does the MXLDA3KP6.5A support IEC61000-4-5 secondary lightning protection, and at which classes?
Yes, the MXLDA3KP6.5A is validated for IEC61000-4-5 secondary lightning protection across multiple source impedances: Class 1–4 with 42 Ω, Class 1–3 with 12 Ω, and Class 2 with 2 Ω source impedance. These classifications are explicitly confirmed in the RF01243 datasheet, enabling direct use in telecom, industrial, and transportation systems requiring certified surge immunity without additional derating or external components.
What is the polarity configuration and pin identification method for the MXLDA3KP6.5A?
The MXLDA3KP6.5A is a unidirectional TVS with cathode-anode polarity. Pin 1 is identified by a dot on the top surface of the package, and per Microsemi's documentation, odd-numbered pins (Pin 1) serve as cathodes. This configuration requires Pin 1 to be connected to the line being protected and Pin 2 to system ground to enable proper avalanche conduction during overvoltage events.
How does the MXLDA3KP6.5A differ from the bidirectional MDA3KP6.5CA variant?
The MXLDA3KP6.5A is unidirectional and protects only positive-going transients on DC lines, whereas the MDA3KP6.5CA is bidirectional and handles both polarities-making it suitable for AC-coupled signals or floating buses like RS-485. The MXLDA3KP6.5A offers tighter V(BR) tolerance (±5%) and lower clamping voltage in forward conduction mode, while the CA version sacrifices some precision for symmetrical bipolar clamping behavior.
