Product details
Overview
MXLDA3KP7.0AE3 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 7.0 V reverse standoff voltage (VWM), 7.78–8.6 V breakdown voltage (V(BR)), 12.0 V maximum clamping voltage at 250 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MXLDA3KP7.0AE3 datasheet, MXLDA3KP7.0AE3 pinout, MXLDA3KP7.0AE3 application, or MXLDA3KP7.0AE3 equivalent, key selection criteria include IEC 61000-4-2/4-4/4-5 compliance, 10/1000 µs surge rating, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility for aerospace and defense systems.
Technical Context
The MXLDA3KP7.0AE3 is a single-channel unidirectional TVS diode optimized for fast clamping of high-energy transients. Its <100 ps response time enables effective ESD suppression per IEC 61000-4-2, while its 3000 W peak pulse power rating at 10/1000 µs supports secondary lightning protection per IEC 61000-4-5 with 42 Ω, 12 Ω, and 2 Ω source impedances.
It uses void-free UL94V-0 epoxy packaging with tin-lead or annealed matte-tin terminations compliant with MIL-STD-750 Method 2026. Polarity is defined by dot marking; odd-numbered pins are cathodes, confirming its unidirectional configuration per part nomenclature "A" suffix and absence of "C".
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - Maximum continuous DC or RMS operating voltage before clamping initiates |
| V(BR) min/max | 7.78–8.6 V @ 10 mA - Ensures reliable turn-on above normal operating voltage with margin |
| VC @ IPP | 12.0 V @ 250 A - Clamped voltage during worst-case 10/1000 µs surge, limiting downstream stress |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy surges without failure in industrial or telecom power inputs |
| ID @ VWM | 200 µA - Low leakage preserves efficiency in battery-backed or low-power monitoring circuits |
| TJ range | –55 °C to +150 °C - Supports operation in under-hood automotive, industrial motor drives, and avionics |
Pinout & Package
MXLDA3KP7.0AE3 is housed in a surface-mount vertical package with 2 terminals (cathode/anode), marked with a dot indicating Pin 1 (cathode). The case is void-free thermosetting epoxy meeting UL94V-0; terminals use annealed matte-tin plating per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Dot-marked) | Cathode | Connected to protected line; clamps when voltage exceeds V(BR) relative to anode |
| Pin 2 | Anode | Typically tied to ground or lower-potential rail; completes conduction path during transient |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | 600 W PPP rating, 10.0 V VC @ 33.3 A - lower energy handling and higher clamping | Best suited for low-energy ESD/EFT only; insufficient for IEC 61000-4-5 Class 3+ lightning | Select MXLDA3KP7.0AE3 when 3000 W surge immunity and 12.0 V clamping are required for industrial or telecom mains input stages |
| SMCJ7.0A | 1500 W PPP rating, 12.0 V VC @ 125 A - half the peak power, same clamping voltage | Adequate for Class 2 lightning per IEC 61000-4-5 but not Class 3/4 with 42 Ω source impedance | Choose MXLDA3KP7.0AE3 where full 3000 W capability and MIL-PRF-19500 upscreening eligibility are mandatory |
Compared with SMBJ7.0A and SMCJ7.0A, MXLDA3KP7.0AE3 delivers double the peak pulse power of SMCJ7.0A and five times that of SMBJ7.0A while maintaining identical clamping voltage-enabling single-device protection for high-energy industrial surges without parallel stacking.

FAQ
What is the clamping voltage of MXLDA3KP7.0AE3 at its rated peak pulse current?
The MXLDA3KP7.0AE3 has a maximum clamping voltage (VC) of 12.0 V at 250 A peak pulse current under 10/1000 µs waveform conditions. This value is guaranteed across the full operating temperature range and ensures downstream circuitry remains within safe voltage limits during high-energy transients. The MXLDA3KP7.0AE3 achieves this with sub-100 ps response time, making it suitable for protecting sensitive 3.3 V and 5 V logic interfaces.
Is MXLDA3KP7.0AE3 RoHS-compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP7.0AE3 is RoHS-compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide. The 'e3' designation specifies annealed matte-tin plating on terminals, fully compliant with EU RoHS Directive 2011/65/EU and compatible with Pb-free reflow soldering per IPC/JEDEC J-STD-020B Level 1. The MXLDA3KP7.0AE3 requires no dry pack and supports standard SMT assembly processes.
Can MXLDA3KP7.0AE3 be used for bidirectional transient protection?
No, MXLDA3KP7.0AE3 is strictly unidirectional, indicated by the 'A' (not 'C') suffix in its nomenclature and confirmed by its single-polarity electrical characteristics. It conducts only when cathode voltage exceeds anode voltage by ≥V(BR). For bidirectional protection, Microsemi offers the MDA3KP7.0CE3 variant. Using MXLDA3KP7.0AE3 in AC-coupled or bipolar signal paths would result in forward conduction during negative half-cycles and potential failure.
What is the maximum steady-state leakage current of MXLDA3KP7.0AE3 at its rated standoff voltage?
The MXLDA3KP7.0AE3 exhibits a maximum standby current (ID) of 200 µA at its rated reverse standoff voltage (VWM) of 7.0 V and 25 °C ambient. This low leakage preserves power efficiency in always-on systems such as battery-backed sensors or remote telemetry units. Leakage remains within specification across the full –55 °C to +150 °C junction temperature range, verified per Microsemi's 3σ lot norm screening.
Does MXLDA3KP7.0AE3 support high-reliability screening per MIL-PRF-19500?
Yes, MXLDA3KP7.0AE3 qualifies for optional upscreening per MIL-PRF-19500, including wafer fabrication and assembly lot traceability, 3σ lot norm screening on ID, and surge testing per test method 3012. Screening options are detailed in Micronote 129. The MXLDA3KP7.0AE3 base configuration meets commercial reliability standards; MIL-PRF-19500 compliance requires explicit ordering with appropriate screening codes and is subject to factory quotation.
