Product details
Overview
MXLDA3KP11AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 11 V standoff voltage (VWM), 12.2–13.5 V breakdown voltage (V(BR)), and 18.2 V maximum clamping voltage (VC) at 164.8 A peak pulse current. It provides secondary lightning protection per IEC61000-4-5 (42 Ω, Class 1–4), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in DC power rails.
For engineers reviewing the MXLDA3KP11AE3 datasheet, MXLDA3KP11AE3 pinout, MXLDA3KP11AE3 application, or MXLDA3KP11AE3 equivalent, key selection criteria include standoff voltage matching system peak operating voltage, clamping voltage margin relative to protected IC absolute maximum ratings, surge current capability under 10/1000 µs waveform, RoHS-compliant e3 termination, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MXLDA3KP11AE3 operates as a unidirectional avalanche diode-based TVS, triggered when reverse voltage exceeds its 12.2–13.5 V breakdown range. Its <100 ps response time enables effective suppression of ESD events and fast transients before downstream components are stressed.
It is rated for 3000 W peak pulse power (10/1000 µs), with clamping limited to 18.2 V at 164.8 A IPP, and exhibits ≤5 µA standby current at 11 V VWM. The device supports operation from –55 °C to +150 °C and features void-free UL94V-0 epoxy packaging with tin-lead or matte-tin terminations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11 V - Maximum continuous DC or peak AC voltage the device blocks without conduction. |
| V(BR) min/max | 12.2–13.5 V @ 1 mA - Confirmed avalanche onset range; ensures reliable triggering above system operating voltage. |
| VC @ IPP | 18.2 V @ 164.8 A - Clamped voltage during 10/1000 µs surge; defines worst-case stress on protected load. |
| PPP | 3000 W @ 10/1000 µs - Peak transient energy handling capacity; validated per Figure 1 derating curve. |
| ID @ VWM | ≤5 µA - Leakage current at rated standoff; negligible power loss in high-impedance monitoring or bias circuits. |
| TJ/TSTG | –55 to +150 °C - Extended temperature range supports industrial, aerospace, and automotive under-hood applications. |
Pinout & Package
MXLDA3KP11AE3 uses a 2-pin DO-214AB (SMC) package with cathode-anode polarity: Pin 1 is cathode (marked by dot), Pin 2 is anode. Body dimensions: 21.03–22.05 mm × 6.86–7.87 mm × 8.64–9.65 mm (L×W×H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; conducts surge current to ground/anode when Vreverse > V(BR). |
| Pin 2 | Anode | Typically tied to system ground or low-impedance return path; completes conduction loop during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse rating | Validated for 10/1000 µs waveform - handles high-energy lightning-induced surges without failure. |
| RoHS-compliant e3 termination | Matte-tin plating per MIL-STD-750 Method 2026 - ensures solderability and long-term intermetallic stability. |
| MIL-PRF-19500 upscreening option | Available with wafer/lot traceability and 3σ screening on ID - meets high-reliability requirements for defense/aerospace programs. |
| Moisture sensitivity Level 1 | No dry pack required per J-STD-020B - simplifies SMT handling and eliminates bake-out steps pre-reflow. |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|
Use Scenario: DC bus lines in variable-frequency drives exposed to inductive kickback from contactor switching and regenerative braking. IC Role / Device Role / Timing Role: Unidirectional TVS placed between +BUS and GND to clamp negative-going transients below MOSFET/GaN FET drain-source breakdown limits. Use Value: Limits clamping voltage to 18.2 V, preserving 20 V-rated gate drivers and enabling use of lower-voltage, higher-efficiency power switches. | Use Scenario: -48 V DC power input stage of telecom base station equipment subject to lightning-induced surges on outdoor feeder lines. IC Role / Device Role / Timing Role: Primary overvoltage protector on the DC input rail upstream of DC/DC converters and PMICs. Use Value: Withstands 3000 W surges per IEC61000-4-5 (42 Ω source), preventing latch-up or burnout in downstream POL regulators. |
| Railway Signaling Interfaces | Medical Imaging Power Supplies |
Use Scenario: 24 V control signal lines in track-side signaling units subjected to EFT bursts and coupling from adjacent traction power cables. IC Role / Device Role / Timing Role: Point-of-load TVS on isolated CAN or RS-485 interface power rails to suppress coupled transients. Use Value: Sub-100 ps response captures fast EFT edges (5 ns rise time), limiting voltage overshoot to <18.2 V and maintaining signal integrity across isolation barriers. | Use Scenario: High-voltage DC link (±15 V to ±24 V) in CT/MRI detector module power supplies where transient immunity directly impacts image noise floor. IC Role / Device Role / Timing Role: Secondary protection element after primary MOVs, providing precise clamping to protect low-noise LDOs and ADC reference buffers. Use Value: 5 µA max leakage at 11 V VWM avoids loading precision references; tight V(BR) tolerance (±5%) ensures consistent trip threshold across production lots. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | 600 W PPP rating, same VWM/V(BR)/VC but lower IPP (59.5 A); DO-214AC (SMA) package, smaller footprint. | Not suitable for IEC61000-4-5 Class 4 or high-energy inductive switching; limited to ESD/EFT and low-energy transients. | Select SMAJ11A only when board space is constrained and surge energy remains below 600 W. |
| 1.5KE11A | 1500 W PPP, axial-leaded DO-15 package; higher thermal resistance and manual assembly requirement. | Not compatible with automated SMT lines; unsuitable for high-density PCBs or vibration-prone environments due to leaded construction. | Choose 1.5KE11A only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMAJ11A and 1.5KE11A, MXLDA3KP11AE3 delivers double the surge energy handling of the former and twice the power rating of the latter while maintaining SMT compatibility, making it the sole choice for new industrial and telecom designs requiring full IEC61000-4-5 Class 4 compliance.

FAQ
What is the clamping voltage of MXLDA3KP11AE3 at its rated peak pulse current?
The MXLDA3KP11AE3 has a maximum clamping voltage (VC) of 18.2 V at its rated peak pulse current (IPP) of 164.8 A under 10/1000 µs waveform conditions. This value is measured per standard test methods defined in the datasheet and represents the upper bound of voltage seen by protected circuitry during worst-case surge events. Designers must ensure this clamping level remains below the absolute maximum ratings of downstream components.
Is MXLDA3KP11AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP11AE3 is RoHS compliant. The 'e3' suffix explicitly denotes matte-tin termination meeting JEDEC/IPC RoHS requirements, with no lead or other restricted substances exceeding allowable thresholds. This plating also complies with MIL-STD-750 Method 2026 for solderability and intermetallic reliability, supporting both lead-free and SnPb reflow profiles without degradation.
Can MXLDA3KP11AE3 be used for bidirectional transient protection?
No, MXLDA3KP11AE3 is unidirectional. Its part number lacks the 'C' suffix (e.g., MDA3KP11CE3), which designates bidirectional construction. Using MXLDA3KP11AE3 in AC or bipolar signal paths will result in forward conduction during negative half-cycles, potentially damaging the device or circuit. For bidirectional protection at 11 V, specify MDA3KP11CE3 instead.
What is the maximum operating temperature range for MXLDA3KP11AE3?
MXLDA3KP11AE3 is rated for junction and storage temperatures from –55 °C to +150 °C. This extended range is validated per manufacturer testing and supports deployment in harsh environments such as under-hood automotive ECUs, railway traction control cabinets, and outdoor telecom enclosures without derating until ambient exceeds 70 °C (per Figure 3 derating curve).
Does MXLDA3KP11AE3 require moisture-sensitive handling prior to reflow?
No, MXLDA3KP11AE3 has IPC/JEDEC J-STD-020B moisture sensitivity level (MSL) 1, meaning it may be stored indefinitely at ≤30 °C/60% RH without dry packing or baking. This eliminates pre-reflow bake cycles, reduces manufacturing overhead, and avoids thermal stress on the epoxy body - a key advantage over MSL 2a/3 devices in high-volume SMT lines.
