Product details
Overview
MXLDA3KP6.5AE3 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, designed for secondary lightning protection per IEC61000-4-5 and ESD/EFT suppression in industrial power interfaces.
For engineers reviewing the MXLDA3KP6.5AE3 datasheet, MXLDA3KP6.5AE3 pinout, MXLDA3KP6.5AE3 application, or MXLDA3KP6.5AE3 equivalent, key selection criteria include its 6.5 V working voltage, 11.2 V clamping performance at 267.9 A, RoHS-compliant e3 plating, -55°C to +150°C junction temperature range, and MIL-PRF-19500 upscreening capability for high-reliability deployments.
Technical Context
The MXLDA3KP6.5AE3 operates as a unidirectional avalanche diode-based TVS, triggered when reverse voltage exceeds its 7.22–7.98 V breakdown threshold. It delivers sub-100 ps response time and clamps transients to ≤11.2 V at 267.9 A under 10/1000 μs waveform conditions.
Its 3000 W peak pulse power rating is validated per Figure 1 of RF01243 Rev B, with derating applied above 25°C per Figure 3. Standby leakage remains ≤500 μA at 6.5 V VWM, supporting low-power system monitoring without loading sensitive inputs.
Key Specifications

Pinout & Package
MXLDA3KP6.5AE3 uses a 3-pin surface-mount package with void-free UL94V-0 epoxy body and tin-lead or matte-tin (e3) plating. Pin 1 is cathode, defined by a dot on top; odd-numbered pins are cathodes per device polarity convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; conducts during overvoltage to shunt current to ground |
| Pin 2 | Anode | Common anode connection for multi-diode array; tied to system ground reference |
| Pin 3 | Cathode | Second cathode terminal for dual-channel configuration or redundancy path |

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 - lower energy handling | Not suitable for Class 4 lightning per IEC61000-4-5; limited to ESD/EFT-only zones | Select only where surge amplitude and repetition rate are significantly lower than industrial mains-connected systems |
| SMCJ6.5A | 1500 W PPP rating, SMC package, 11.2 V VC @ 133.9 A - half the energy capacity of MXLDA3KP6.5AE3 | Valid for Class 1–2 lightning only (42 Ω/12 Ω sources); insufficient for Class 3/4 requirements | Use when board space constraints prevent TO-277A footprint but full 3000 W rating is not required |
Compared with SMAJ6.5A and SMCJ6.5A, MXLDA3KP6.5AE3 provides double the peak pulse power and verified Class 1–4 lightning compliance, making it the sole choice for mission-critical infrastructure where 3000 W transient absorption must be guaranteed without layout redesign.

FAQ
What is the clamping voltage of MXLDA3KP6.5AE3 at its rated peak pulse current?
The MXLDA3KP6.5AE3 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 Figure 2 in RF01243 Rev B and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MXLDA3KP6.5AE3 maintains this clamping performance across its full operating temperature range.
Is MXLDA3KP6.5AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP6.5AE3 is RoHS compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide on Page 2 of RF01243 Rev B. The 'e3' designation specifies annealed matte-tin plating that meets J-STD-020B Level 1 moisture sensitivity requirements and ensures solderability per MIL-STD-750 Method 2026 without dry packing.
Can MXLDA3KP6.5AE3 be used for bidirectional transient protection?
No, MXLDA3KP6.5AE3 is a unidirectional TVS device, as indicated by the absence of 'C' in its part number. Bidirectional variants such as MDA3KP6.5CA exist in the same family but differ in internal construction and polarity behavior. Using MXLDA3KP6.5AE3 in AC-coupled or bipolar signal paths would result in forward conduction during negative half-cycles and potential damage.
What is the maximum standoff voltage (VWM) and how does it relate to system design?
The MXLDA3KP6.5AE3 has a rated working standoff voltage (VWM) of 6.5 V, meaning it remains non-conductive up to this peak reverse voltage across its operating temperature range. System designers must ensure that normal operating voltage - including ripple, tolerance, and temperature drift - stays below 6.5 V to avoid premature conduction. Exceeding VWM risks increased standby current and accelerated degradation of the MXLDA3KP6.5AE3.
Does MXLDA3KP6.5AE3 require special handling or baking before reflow soldering?
No, MXLDA3KP6.5AE3 does not require baking or dry packing prior to reflow soldering. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1, confirmed in the Features section of RF01243 Rev B. This allows standard SMT assembly processes without preconditioning, reducing manufacturing complexity and cost while ensuring reliability of the MXLDA3KP6.5AE3 after soldering.
