Product details
Overview
MXLDA3KP6.5CA 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 protection per IEC61000-4-5 (12 Ω and 2 Ω source impedances), ESD suppression per IEC61000-4-2, and inductive switching transient clamping in power supply inputs and telecom interfaces.
For engineers reviewing the MXLDA3KP6.5CA datasheet, MXLDA3KP6.5CA pinout, MXLDA3KP6.5CA application, or MXLDA3KP6.5CA equivalent, key selection criteria include its 6.5 V standoff voltage (VWM), 11.2 V maximum clamping voltage at 267.9 A peak pulse current, bidirectional polarity, and MIL-PRF-19500 upscreening capability for aerospace and defense systems.
Technical Context
The MXLDA3KP6.5CA operates as a silicon avalanche diode-based TVS array with symmetrical bidirectional breakdown behavior, enabling protection of AC-coupled or differential signal lines without polarity constraints. Its sub-5 ns response time ensures effective suppression of EFT (IEC61000-4-4) and fast-rising ESD events.
It delivers 3000 W peak pulse power at the standard 10/1000 µs waveform, with clamping performance validated across -55 °C to +150 °C junction temperature range. Standby leakage remains ≤500 µA at 6.5 V, supporting low-power system monitoring integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum continuous operating voltage before conduction; matches nominal 5 V rail with margin for ripple and tolerance. |
| V(BR) min/max | 7.22–7.98 V - Breakdown initiates within this range at 10 mA; ensures reliable turn-on above normal operating peaks. |
| VC @ IPP | 11.2 V at 267.9 A - Clamped voltage seen by protected circuit during worst-case surge; limits downstream stress. |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy transients typical of lightning-induced surges in industrial Ethernet or PoE ports. |
| ID @ VWM | ≤500 µA - Low leakage preserves battery life and avoids false triggering in always-on monitoring circuits. |
| TJ/TSTG | -55 to +150 °C - Enables deployment in under-hood automotive ECUs, base station power supplies, and military avionics enclosures. |
Pinout & Package
MXLDA3KP6.5CA uses a DO-214AB (SMC) surface-mount package: void-free UL94V-0 epoxy body, matte-tin-plated terminals, 5 g mass, and polarity defined by dot marking indicating Pin 1 (cathode for unidirectional variants; symmetrical for bidirectional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode Pair | Bidirectional avalanche junction | Provides symmetrical clamping for AC signals or differential buses; no DC bias dependency. |
| Case / Body | Thermal path & mechanical anchor | DO-214AB copper lead frame enables 1.5 W thermal dissipation in 25 °C still air; requires ≥25 mm² 2-oz copper pad. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection of balanced lines (e.g., RS-485, CAN FD, Ethernet PHY) without polarity concerns. |
| MIL-PRF-19500 screening option | Supports high-reliability qualification for space-grade and airborne systems via wafer lot traceability and 3σ ID screening. |
| 10/1000 µs surge rating | Validated for IEC61000-4-5 Class 1–3 (12 Ω) and Class 4 (2 Ω) secondary lightning waveforms in telecom infrastructure. |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow; compatible with standard J-STD-020B assembly flow. |

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 VC but lower IPP (103 A vs. 267.9 A); DO-214AA package. | Limited to lower-energy surges (e.g., board-level ESD only); unsuitable for IEC61000-4-5 Class 3 or lightning scenarios. | Select SMBJ6.5CA only when surge energy is constrained to <600 W and PCB space is critical. |
| SMCJ6.5CA | 1500 W PPP; identical DO-214AB package; VC = 11.4 V at 131 A IPP; no MIL-PRF-19500 screening option. | Meets IEC61000-4-5 Class 1–2 (12 Ω) but not Class 3; lacks high-reliability screening for mission-critical use. | Choose SMCJ6.5CA for cost-sensitive industrial designs where full 3000 W rating and upscreening are unnecessary. |
Compared with SMBJ6.5CA and SMCJ6.5CA, MXLDA3KP6.5CA uniquely delivers 3000 W surge handling in DO-214AB with optional MIL-PRF-19500 qualification-making it the only choice for telecom central office equipment and avionics power entry protection requiring Class 3 lightning compliance and lot traceability.

FAQ
What is the clamping voltage of MXLDA3KP6.5CA at its rated peak pulse current?
The MXLDA3KP6.5CA has a maximum clamping voltage (VC) of 11.2 V at its rated peak pulse current (IPP) of 267.9 A under the 10/1000 µs waveform. This value is measured per Figure 2 in the RF01243 datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MXLDA3KP6.5CA maintains this clamping performance across its full operating temperature range.
Is MXLDA3KP6.5CA RoHS compliant?
Yes, MXLDA3KP6.5CA is RoHS compliant, indicated by the "e3" suffix in its full part marking per Microsemi's nomenclature guide on page 2 of RF01243. The device uses annealed matte-tin plating on terminals and void-free UL94V-0 epoxy packaging, meeting EU Directive 2011/65/EU requirements without exemptions.
Does MXLDA3KP6.5CA support MIL-PRF-19500 high-reliability screening?
Yes, MXLDA3KP6.5CA supports optional MIL-PRF-19500 upscreening with wafer lot traceability and 3σ standby current (ID) screening, as documented in Micronote 129 referenced in the RF01243 datasheet. This makes MXLDA3KP6.5CA suitable for aerospace, defense, and other high-integrity applications requiring certified reliability data.
What is the standoff voltage (VWM) and why is it critical for MXLDA3KP6.5CA selection?
The MXLDA3KP6.5CA has a rated working standoff voltage (VWM) of 6.5 V, meaning it remains non-conductive below this peak voltage. This parameter is critical because it must exceed the maximum expected normal operating voltage-including ripple, tolerance, and transients-to avoid false triggering. For example, MXLDA3KP6.5CA is correctly selected for 5 V systems with ≤10% tolerance and ±0.5 V ripple.
How does the bidirectional configuration of MXLDA3KP6.5CA affect its use in differential signal lines?
The bidirectional configuration of MXLDA3KP6.5CA allows symmetrical clamping of both positive and negative transients on differential pairs like RS-485 or CAN, eliminating the need for dual unidirectional devices or polarity-aware layout. This simplifies PCB design, reduces component count, and ensures consistent protection regardless of signal swing direction-key for MXLDA3KP6.5CA deployment in full-duplex industrial networks.
