Product details
Overview
MXLDA3KP8.5CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, featuring 8.5 V reverse standoff voltage (VWM), 9.44–10.4 V breakdown voltage (V(BR)), and 14.4 V maximum clamping voltage (VC) at 208.4 A peak pulse current (IPP). It delivers secondary lightning protection per IEC61000-4-5 (42 Ω, Class 1–4) and ESD/EFT suppression per IEC61000-4-2/4-4 in telecom power interfaces.
For engineers reviewing the MXLDA3KP8.5CAE3 datasheet, MXLDA3KP8.5CAE3 pinout, MXLDA3KP8.5CAE3 application, or MXLDA3KP8.5CAE3 equivalent, this device is selected for high-reliability DC power rail protection where fast response (<5 ns), RoHS-compliant packaging, and MIL-PRF-19500 upscreening capability are required.
Technical Context
The MXLDA3KP8.5CAE3 is a bidirectional TVS diode array designed for symmetric surge suppression on AC-coupled or floating lines. Its sub-5 ns response time enables effective clamping of ESD events and fast transients before downstream circuitry sustains damage.
It operates across –55 °C to +150 °C junction temperature, with 100% surge testing per lot and 3σ screening on standby current (ID ≤ 25 µA at VWM). The device uses void-free UL94V-0 epoxy molding and matte-tin plating compliant with MIL-STD-750 Method 2026.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.5 V - Maximum continuous DC or RMS operating voltage the device blocks without conduction |
| V(BR) min/max | 9.44–10.4 V @ 1 mA - Ensures reliable turn-on above normal operating peaks while avoiding false triggering |
| VC @ IPP | 14.4 V @ 208.4 A - Limits voltage seen by protected ICs during 10/1000 µs surges to safe levels |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy transients common in industrial power inputs and telecom lines |
| ID @ VWM | ≤25 µA - Minimizes leakage impact on low-power sensor or battery-backed circuits |
| TJ range | –55 °C to +150 °C - Supports operation in extended-temperature automotive and aerospace environments |
Pinout & Package
MXLDA3KP8.5CAE3 is housed in a DO-214AB (SMC) surface-mount package with dual anode-cathode symmetrical terminals. Polarity is defined by a dot marking indicating Pin 1 (cathode for unidirectional variants); for bidirectional MXLDA3KP8.5CAE3, both terminals are functionally identical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 / Cathode 1 | Surge current input path (terminal A) | Accepts transient energy from Line 1; conducts bidirectionally to terminal B during overvoltage |
| Anode 2 / Cathode 2 | Surge current return path (terminal B) | Completes clamping loop; referenced to system ground or complementary line in differential pair |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetric clamping on AC signals or floating buses without polarity constraints |
| 3000 W peak pulse power | Handles high-energy lightning-induced surges in telecom central office and base station power feeds |
| RoHS-compliant e3 finish | Meets global environmental compliance requirements without compromising solderability or thermal cycling reliability |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring wafer lot traceability, burn-in, and parametric screening |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.5CA | 600 W PPP rating, same VWM and bidirectional configuration, DO-214AA package | Lower energy handling; suitable only for ESD/EFT, not Class 4 lightning | Select when surge threat level is limited to IEC61000-4-2/4-4 and PCB space is constrained |
| 1.5KE8.5CA | 3000 W PPP but through-hole DO-15 package, higher clamping voltage (15.0 V) | Requires wave soldering; incompatible with fully SMT production flows | Choose only for legacy through-hole designs where rework tolerance and manual assembly are acceptable |
Compared with SMBJ8.5CA and 1.5KE8.5CA, MXLDA3KP8.5CAE3 uniquely combines 3000 W surge capacity, surface-mount DO-214AB packaging, and MIL-PRF-19500 upscreening readiness-making it optimal for new high-reliability telecom and industrial designs requiring automated assembly and lightning-class immunity.

FAQ
What is the clamping voltage of MXLDA3KP8.5CAE3 at its rated peak pulse current?
The MXLDA3KP8.5CAE3 has a maximum clamping voltage (VC) of 14.4 V at its rated peak pulse current (IPP) of 208.4 A under 10/1000 µs waveform conditions. This value is guaranteed across temperature and ensures protected downstream circuitry remains below critical voltage thresholds during surge events. The MXLDA3KP8.5CAE3 achieves this with sub-5 ns response time and symmetric bidirectional conduction.
Is MXLDA3KP8.5CAE3 RoHS-compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP8.5CAE3 is RoHS-compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide. The 'e3' denotes annealed matte-tin plating meeting JEDEC/IPC standards, with no lead or hazardous substances exceeding EU RoHS Directive limits. This finish ensures compatibility with lead-free reflow profiles and long-term solder joint reliability in MXLDA3KP8.5CAE3 deployments.
How does the bidirectional configuration of MXLDA3KP8.5CAE3 affect its use in circuit design?
The bidirectional configuration of MXLDA3KP8.5CAE3 allows it to clamp both positive and negative transients equally across its two terminals, eliminating polarity concerns in AC-coupled, floating, or differential signal paths. Unlike unidirectional TVS devices, MXLDA3KP8.5CAE3 requires no ground reference for basic operation and can be placed directly across lines-making it ideal for protecting RS-485 buses or isolated DC power rails where voltage reversal may occur.
Can MXLDA3KP8.5CAE3 be used for IEC61000-4-5 Class 4 lightning surge protection?
Yes, MXLDA3KP8.5CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as documented in the RF01243 datasheet. Its 3000 W peak pulse power and 14.4 V clamping voltage enable compliance when applied with appropriate PCB layout (e.g., short traces, low-inductance grounding). MXLDA3KP8.5CAE3 meets this requirement without derating up to +85 °C ambient.
What is the maximum operating temperature range for MXLDA3KP8.5CAE3?
MXLDA3KP8.5CAE3 is rated for junction temperatures from –55 °C to +150 °C, supporting deployment in extended-temperature environments such as under-hood automotive electronics, outdoor telecom cabinets, and industrial motor drives. This range is validated per Microsemi's qualification testing and applies across all electrical parameters unless otherwise specified in the MXLDA3KP8.5CAE3 datasheet.
