Product details
Overview
MXLDA3KP9.0CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability secondary lightning and ESD protection. It features a 9.0 V reverse standoff voltage (VWM), 10.0–11.1 V breakdown voltage (V(BR)), 15.4 V maximum clamping voltage at 194.8 A peak pulse current, and operates from −55 °C to +150 °C - deployed in telecom power interfaces and industrial I/O protection circuits.
For engineers reviewing the MXLDA3KP9.0CA datasheet, MXLDA3KP9.0CA pinout, MXLDA3KP9.0CA application, or MXLDA3KP9.0CA equivalent, key selection criteria include bidirectional polarity, 10/1000 µs surge rating, IEC61000-4-2/4-4/4-5 compliance, clamping performance under 194.8 A IPP, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MXLDA3KP9.0CA implements a silicon avalanche diode structure optimized for sub-nanosecond response (<5 ns) to fast transients. Its bidirectional configuration enables symmetrical clamping across both polarities without external circuitry, supporting AC-coupled signal lines and ungrounded bus protection.
It is rated for 3000 W peak pulse power per 10/1000 µs waveform, with full surge testing performed per unit, and meets moisture sensitivity Level 1 (IPC/JEDEC J-STD-020B) - eliminating dry-pack requirements and enabling standard reflow processing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - maximum continuous operating voltage before conduction begins; matches 9 V nominal DC rails or ±9 V analog interfaces. |
| V(BR) min/max | 10.0–11.1 V - guaranteed avalanche onset range at 1 mA; ensures predictable turn-on margin above VWM. |
| VC @ IPP | 15.4 V - clamping voltage at 194.8 A peak pulse; limits downstream voltage stress during IEC61000-4-5 Class 4 events. |
| IPP | 194.8 A - peak impulse current supported at 10/1000 µs; defines maximum transient energy absorption capability. |
| TJ range | −55 °C to +150 °C - extended thermal envelope supports under-hood automotive, base station, and industrial control environments. |
| Package | DO-214AB (SMC) - standardized surface-mount outline with 21.03 × 22.05 mm body; compatible with automated placement and IPC-compliant reflow. |
Pinout & Package
MXLDA3KP9.0CA uses a 2-terminal DO-214AB (SMC) package with cathode marked by a dot on the top surface. Pin 1 is cathode; Pin 2 is anode. Bidirectional operation means both terminals function symmetrically as either anode or cathode depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (marked) | Reference terminal for polarity marking; forms one side of bidirectional avalanche junction. |
| Pin 2 | Anode | Complementary terminal; completes symmetrical clamping path for positive/negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection of AC signals, differential buses, or floating nodes without polarity constraints. |
| 3000 W peak pulse power | Sustains 10/1000 µs surges up to 194.8 A - sufficient for IEC61000-4-5 Class 4 (2 Ω source) and telecom lightning standards. |
| MIL-PRF-19500 screening option | Supports high-reliability qualification including lot traceability, 3σ ID screening, and wafer-level reliability controls. |
| Level 1 moisture sensitivity | Eliminates baking requirement prior to SMT assembly - reduces process cost and avoids thermal damage risk. |
Applications
| Telecom Line Interface Protection | Industrial PLC Analog I/O Protection |
|---|---|
Use Scenario: Protecting RS-485/RS-422 transceivers connected to outdoor wiring exposed to induced lightning surges. IC Role / Device Role / Timing Role: Bidirectional TVS array clamping differential line transients before they reach the transceiver IC input stage. Use Value: Limits line-to-line voltage to ≤15.4 V during 194.8 A surges, preventing latch-up or gate oxide damage in 3.3 V/5 V interface ICs. | Use Scenario: Shielding 4–20 mA current loop inputs in programmable logic controllers from field-wiring EFT and switching noise. IC Role / Device Role / Timing Role: Fast-response (sub-5 ns) transient clamp placed across loop terminals to shunt surge energy away from precision ADC front-end. Use Value: Maintains signal integrity by clamping transients within 10.0–11.1 V breakdown window while surviving repeated 10/1000 µs impulses. |
| Automotive Body Control Module (BCM) Power Input | Medical Equipment ESD-Sensitive Sensor Interface |
Use Scenario: Guarding 12 V supply rail inputs in BCM modules against load-dump and jump-start transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power entry point, coordinated with upstream fuses and downstream LDOs. Use Value: Withstands 3000 W pulses and operates up to +150 °C - suitable for under-hood deployment without derating. | Use Scenario: Safeguarding low-noise amplifiers and sigma-delta ADCs in patient-connected biosensors from human-body-model ESD events. IC Role / Device Role / Timing Role: Final-stage ESD suppressor placed immediately before sensor signal conditioning circuitry. Use Value: Sub-5 ns response and <10 µA standby current prevent signal offset drift while meeting IEC61000-4-2 Level 4 (15 kV air) requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0CA | 600 W rating (vs. 3000 W); lower IPP (100 A); same DO-214AA package but smaller footprint. | Suitable for board-level ESD only; insufficient for IEC61000-4-5 Class 4 or lightning-induced surges. | Select when space-constrained and surge energy is limited to <600 W. |
| SMCJ9.0CA | 1500 W rating; IPP = 137 A; identical DO-214AB package and pinout. | Meets IEC61000-4-5 Class 3 (12 Ω source) but not Class 4 (2 Ω source) due to lower power handling. | Choose for cost-sensitive designs where 1500 W suffices and full 3000 W margin is unnecessary. |
Compared with SMBJ9.0CA and SMCJ9.0CA, MXLDA3KP9.0CA delivers 2× and 2× higher peak pulse power respectively, enabling robust secondary lightning protection in infrastructure-grade equipment - critical where 2 Ω source impedance and Class 4 compliance are mandated.

FAQ
What is the clamping voltage of MXLDA3KP9.0CA at its rated peak pulse current?
The MXLDA3KP9.0CA has a maximum clamping voltage (VC) of 15.4 V at its rated peak pulse current (IPP) of 194.8 A under 10/1000 µs waveform conditions. This value is measured across the device terminals during surge conduction and defines the upper voltage limit imposed on protected circuitry during worst-case transients.
Is MXLDA3KP9.0CA RoHS compliant?
Yes, MXLDA3KP9.0CA is RoHS compliant, indicated by the "e3" suffix in its full marking per Microsemi's nomenclature. The device uses annealed matte-tin plating on terminals and void-free UL94V-0 epoxy packaging - fully aligned with Directive 2011/65/EU and subsequent amendments.
Does MXLDA3KP9.0CA require special handling for moisture sensitivity?
No, MXLDA3KP9.0CA is rated at Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions and processed using standard reflow profiles without pre-baking. This eliminates moisture-related popcorning risk and simplifies manufacturing logistics.
Can MXLDA3KP9.0CA be used for IEC61000-4-5 Class 4 lightning protection?
Yes, MXLDA3KP9.0CA is explicitly qualified for IEC61000-4-5 Class 4 secondary lightning protection with 2 Ω source impedance, as confirmed in the Applications/Benefits section of RF01243 Rev B. Its 3000 W rating and 194.8 A IPP meet the 4 kV test level requirement under this condition.
What is the breakdown voltage tolerance for MXLDA3KP9.0CA?
The MXLDA3KP9.0CA has a breakdown voltage (V(BR)) range of 10.0 V to 11.1 V at 1 mA test current, representing a ±5.5% tolerance about the nominal 10.55 V midpoint. This 5% tolerance grade is denoted by the "A" suffix in the part number and ensures consistent turn-on behavior across production lots.
