Product details
Overview
MXLDA3KP7.5AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability overvoltage protection in power rails and signal lines. It features a 7.5 V reverse standoff voltage (VWM), 8.33–9.21 V breakdown voltage (V(BR)), 12.9 V maximum clamping voltage at 100 A peak pulse current, and operates across –55 °C to +150 °C junction temperature. It is used in industrial power supplies and telecom interface circuits requiring IEC61000-4-2/4-4/4-5 compliance.
For engineers reviewing the MXLDA3KP7.5AE3 datasheet, MXLDA3KP7.5AE3 pinout, MXLDA3KP7.5AE3 application, or MXLDA3KP7.5AE3 equivalent, key selection criteria include clamping performance at 100 A IPP, thermal derating above 25 °C, standoff voltage margin relative to DC rail, and RoHS-compliant matte-tin termination for lead-free reflow compatibility.
Technical Context
The MXLDA3KP7.5AE3 employs silicon avalanche diode technology optimized for sub-100 ps response time and low clamping ratio (VC/V(BR) ≈ 1.55). Its unidirectional polarity enables asymmetric protection on positive-rail applications without reverse leakage concerns at VWM.
It is rated for 3000 W peak pulse power under 10/1000 µs waveform, with full surge testing per production lot and traceable wafer/assembly lot control aligned with MIL-PRF-19500 screening options. Moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.5 V - maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 8.33–9.21 V @ 1 mA - ensures reliable avalanche initiation before system damage occurs |
| VC @ IPP | 12.9 V @ 100 A - limits downstream voltage stress during 10/1000 µs transients |
| IPP | 100 A - peak impulse current capability at rated clamping voltage |
| ID @ VWM | 100 µA - low standby leakage preserves efficiency in always-on circuits |
| TJ range | –55 °C to +150 °C - supports operation in harsh industrial and automotive under-hood environments |
| PPP | 3000 W @ 10/1000 µs - defines energy-handling capacity for lightning and switching surge events |
Pinout & Package
MXLDA3KP7.5AE3 uses a 2-pin DO-214AB (SMC) package with cathode-anode configuration. Pin 1 is cathode (marked by dot), Pin 2 is anode. Body is void-free UL94V-0 epoxy; terminals are annealed matte-tin plated per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; conducts when transient exceeds V(BR), shunting current to ground/anode |
| Pin 2 | Anode | Typically tied to ground or lower-potential rail; completes clamping path during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse rating | Enables robust secondary lightning protection per IEC61000-4-5 with 42 Ω source impedance (Class 1–4) |
| 12.9 V clamping @ 100 A | Provides predictable voltage limiting for 24 V industrial control inputs without over-clamping risk |
| RoHS-compliant matte-tin plating | Supports Pb-free reflow profiles up to 260 °C for 10 s without degradation |
| Lot-traceable manufacturing | Ensures full wafer and assembly lot traceability for aerospace and defense programs requiring MIL-PRF-19500 screening |
| Level 1 moisture sensitivity | Eliminates dry-pack requirement and floor-life constraints for automated SMT assembly |
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 |
|---|---|---|---|
| SMBJ7.5A | 600 W PPP rating, same VWM and VC, but lower IPP (64.5 A) and smaller SMB package | Suitable for lower-energy ESD/EFT only; not rated for IEC61000-4-5 Class 4 lightning | Select SMBJ7.5A only if system-level surge energy is confirmed ≤600 W and board space is constrained. |
| 1.5KE7.5A | 3000 W PPP, axial-leaded DO-201 package, higher thermal resistance, no RoHS e3 marking | Requires through-hole assembly; unsuitable for high-density SMT layouts or lead-free processes | Choose 1.5KE7.5A only for legacy through-hole designs where reflow compatibility and surface-mount footprint are not required. |
Compared with SMBJ7.5A and 1.5KE7.5A, MXLDA3KP7.5AE3 delivers identical 7.5 V standoff and superior 3000 W surge handling in a RoHS-compliant SMC package optimized for automated placement and high-reliability thermal cycling.

FAQ
What is the clamping voltage of MXLDA3KP7.5AE3 at its rated peak pulse current?
The MXLDA3KP7.5AE3 has a maximum clamping voltage (VC) of 12.9 V at 100 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value is guaranteed across temperature and production lots, ensuring consistent overvoltage protection for downstream circuitry without exceeding safe voltage thresholds.
Is MXLDA3KP7.5AE3 compatible with lead-free reflow soldering processes?
Yes, MXLDA3KP7.5AE3 features annealed matte-tin plating compliant with MIL-STD-750 Method 2026 and is rated for solder temperature up to 260 °C for 10 seconds. Its e3 suffix confirms RoHS compliance, and its Level 1 moisture sensitivity eliminates dry-pack requirements - making it fully compatible with standard Pb-free reflow profiles.
Does MXLDA3KP7.5AE3 meet IEC61000-4-5 for secondary lightning protection?
Yes, MXLDA3KP7.5AE3 is rated for secondary lightning protection per IEC61000-4-5 with 42 Ω source impedance across Class 1–4, and with 12 Ω and 2 Ω source impedances for specified classes. Its 3000 W peak pulse power rating and validated clamping performance support full compliance when applied per test configuration guidelines.
What is the polarity configuration of MXLDA3KP7.5AE3, and how is it marked?
MXLDA3KP7.5AE3 is a unidirectional TVS array. Polarity is indicated by a dot on the top surface of the package denoting Pin 1 (cathode); Pin 2 is the anode. Odd-numbered pins are cathodes per the family nomenclature, and the "A" suffix (vs. "C") confirms unidirectional construction.
How does the standby leakage current of MXLDA3KP7.5AE3 affect low-power system design?
MXLDA3KP7.5AE3 exhibits a maximum standby current (ID) of 100 µA at its 7.5 V standoff voltage, measured at 25 °C. This low leakage minimizes quiescent power loss in always-on circuits such as battery-backed sensors or remote monitoring nodes, supporting multi-year operation without significant battery drain.
