Product details
Overview
MXLDA3KP8.0CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in industrial and aerospace systems. It features a 8.0 V reverse standoff voltage (VWM), 8.89–9.83 V breakdown voltage (V(BR)), 13.6 V maximum clamping voltage (VC) at 220.6 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MXLDA3KP8.0CA datasheet, MXLDA3KP8.0CA pinout, MXLDA3KP8.0CA application, or MXLDA3KP8.0CA equivalent, key selection criteria include IEC61000-4-5 secondary lightning compliance (Class 1–4 with 42 Ω/12 Ω/2 Ω source impedance), sub-5 ns response time, RoHS-compliant e3 marking, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MXLDA3KP8.0CA is a surface-mount, void-free epoxy-packaged TVS array optimized for fast clamping of high-energy transients. Its bidirectional construction enables symmetrical protection against both positive and negative polarity surges without external polarity management.
It delivers 3000 W peak pulse power at 10/1000 µs waveform, with <5 ns response time and clamping performance validated per IEC61000-4-2 (ESD), -4-4 (EFT), and -4-5 (lightning). Standby leakage is ≤50 µA at 8.0 V, supporting low-power system monitoring integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous operating voltage before clamping begins; matches 5 V or 3.3 V rail systems with margin. |
| V(BR) min/max | 8.89–9.83 V - Confirmed breakdown threshold at 1 mA; ensures predictable turn-on without premature conduction. |
| VC @ IPP | 13.6 V - Clamping voltage at 220.6 A peak pulse; limits downstream voltage stress during 3 kW surges. |
| IPP | 220.6 A - Peak impulse current capability at 10/1000 µs; supports Class 4 lightning protection with 12 Ω source. |
| Response time | <5 ns - Enables effective suppression of ESD (IEC61000-4-2) and fast EFT bursts before IC damage occurs. |
| TJ range | –55 °C to +150 °C - Supports operation in extended-temperature environments including avionics and motor drives. |
| RoHS | e3 marking - Matte-tin plating compliant with RoHS Directive 2011/65/EU; no lead or hazardous substance restrictions violated. |
Pinout & Package
MXLDA3KP8.0CA uses a 2-pin surface-mount package with void-free thermosetting epoxy body (UL94V-0 rated), tin-lead or matte-tin terminations, and polarity defined by dot marking indicating Pin 1. Odd-numbered pins are cathodes - in this 2-pin bidirectional device, Pin 1 and Pin 2 form a symmetrical, non-polarized terminal pair.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | Interchangeable terminal; forms symmetrical surge path with Pin 2 - no DC polarity dependency. |
| Pin 2 | Anode/Cathode (bidirectional) | Interchangeable terminal; completes bidirectional clamping loop - enables placement without orientation constraints. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional architecture | Eliminates need for dual unidirectional devices or polarity-aware layout; reduces BOM count and PCB area by 50%. |
| 3000 W peak pulse rating | Withstands 10/1000 µs surges up to 220.6 A - exceeds IEC61000-4-5 Class 4 requirements with 12 Ω source impedance. |
| MIL-PRF-19500 screening option | Enables high-reliability qualification for aerospace and defense programs requiring lot traceability and 3σ ID screening. |
| Moisture sensitivity Level 1 | No dry pack or baking required prior to reflow - simplifies manufacturing handling and eliminates moisture-related popcorning risk. |
| Sub-5 ns response | Clamps transients before propagation into sensitive analog or digital circuitry - critical for protecting USB, RS-485, and CAN physical layers. |
Applications
| Industrial Motor Drives | Aerospace Avionics |
|---|---|
Use Scenario: Protection of gate drivers and feedback sensors against inductive switching spikes and ground bounce in 48 V–400 V motor control inverters. IC Role / Device Role / Timing Role: Primary surge clamp placed across DC bus or IGBT collector-emitter terminals to limit voltage overshoot during turn-off. Use Value: Prevents cumulative degradation of SiC MOSFETs and isolated gate drivers by limiting transient excursions to ≤13.6 V under 220 A surges. | Use Scenario: Secondary lightning protection on ARINC 429 data lines and MIL-STD-1553 bus stubs in flight control computers. IC Role / Device Role / Timing Role: Bidirectional line protector installed differential-mode across signal pairs to suppress common-mode surges induced by airframe coupling. Use Value: Meets IEC61000-4-5 Class 3 with 12 Ω source and Class 4 with 2 Ω source - validated for DO-160 Section 22 Level 3/4 compliance. |
| Telecom Power Feeds | Medical Imaging Systems |
Use Scenario: Surge protection on -48 V DC telecom power inputs exposed to lightning-induced surges on outdoor plant cabling. IC Role / Device Role / Timing Role: Front-end clamp on primary DC input stage, upstream of DC/DC converters and hot-swap controllers. Use Value: Withstands repeated 3000 W surges without parameter shift; maintains ≤50 µA leakage at nominal -48 V bias for long-term reliability. | Use Scenario: Protection of X-ray detector analog front-ends and CT gantry encoder interfaces against ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-leakage, fast-response clamp on low-noise analog signal paths where standby current must remain below 100 nA. Use Value: Sub-5 ns response prevents transient injection into 24-bit ADC reference rails; clamping at 13.6 V avoids saturation of precision op-amps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA | 600 W rating (vs. 3000 W); 13.6 V VC at 43.5 A IPP; same VWM and bidirectional polarity. | Limited to Class 2 lightning (IEC61000-4-5, 42 Ω source); unsuitable for Class 4 or high-current inductive switching. | Select SMBJ8.0CA only when surge energy is ≤600 W and board space is constrained - not a drop-in replacement for MXLDA3KP8.0CA's 3 kW capability. |
| SMCJ8.0CA | 1500 W rating (vs. 3000 W); 13.6 V VC at 110 A IPP; identical VWM, polarity, and RoHS status. | Meets Class 3 lightning (12 Ω source) but fails Class 4 validation; requires derating above 85 °C ambient. | Use SMCJ8.0CA where cost is prioritized over peak energy handling and full MIL-PRF-19500 screening is unnecessary. |
Compared with SMBJ8.0CA and SMCJ8.0CA, MXLDA3KP8.0CA provides double the peak power rating of SMCJ8.0CA and five times that of SMBJ8.0CA - enabling single-device protection for high-energy industrial and aerospace transients where multi-stage clamping would otherwise be required.
