Product details
Overview
MXLDA3KP9.0AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in power supply inputs, telecom interfaces, and industrial control I/O. 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 (VC) at 194.8 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MXLDA3KP9.0AE3 datasheet, MXLDA3KP9.0AE3 pinout, MXLDA3KP9.0AE3 application, or MXLDA3KP9.0AE3 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, standoff voltage margin versus system DC rail, RoHS-compliant matte-tin termination, and MIL-PRF-19500 upscreening eligibility for aerospace-grade deployments.
Technical Context
The MXLDA3KP9.0AE3 implements a silicon avalanche diode structure optimized for sub-100 ps response time and low clamping ratio (VC/V(BR) ≈ 1.5). Its unidirectional polarity enables asymmetric protection on DC-biased lines, with cathode-defined pin 1 marking per package top dot.
Rated for 3000 W peak pulse power at 10/1000 µs waveform, it meets IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and IEC61000-4-5 (lightning) with 42 Ω, 12 Ω, and 2 Ω source impedances - supporting Class 1–4 compliance depending on impedance configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0A | 600 W rating, 12.6 V clamping at 48.2 A, DO-214AA package | Limited to lower-energy transients; unsuitable for IEC61000-4-5 Class 3/4 with 2 Ω source | Select when board space is constrained and surge threat level is ESD/EFT only |
| 1.5KE9.1A | 1500 W rating, 14.5 V clamping at 103 A, DO-201AD package | Through-hole mounting; higher thermal resistance limits sustained surge duty cycle | Select for legacy through-hole designs where rework to SMD is not feasible |
Compared with SMBJ9.0A and 1.5KE9.1A, MXLDA3KP9.0AE3 delivers 2× and 2× higher peak power handling respectively, with tighter clamping and surface-mount scalability - making it the preferred choice for new industrial and telecom designs requiring IEC61000-4-5 compliance.

FAQ
What is the clamping voltage of MXLDA3KP9.0AE3 at its rated peak pulse current?
The MXLDA3KP9.0AE3 has a maximum clamping voltage (VC) of 15.4 V at its peak pulse current (IPP) of 194.8 A under 10/1000 µs waveform conditions. This value is measured per standard test methods defined in IEC61000-4-5 and ensures predictable voltage limiting during surge events. The MXLDA3KP9.0AE3 achieves this with a clamping ratio of approximately 1.5 relative to its minimum breakdown voltage, confirming robust avalanche behavior without thermal runaway.
Is MXLDA3KP9.0AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP9.0AE3 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 meeting JEDEC J-STD-020B Level 1 moisture sensitivity, eliminating dry-pack requirements and enabling standard reflow profiles. This compliance applies to all homogeneous materials in the device, including the UL94V-0 epoxy body and internal die attach system.
Can MXLDA3KP9.0AE3 be used for bidirectional transient protection?
No, MXLDA3KP9.0AE3 is a unidirectional TVS device, as indicated by the absence of a 'C' suffix in its part number. Bidirectional variants (e.g., MXLDA3KP9.0CE3) use symmetrical avalanche structures for AC line or data bus protection. Using MXLDA3KP9.0AE3 on bidirectional signals risks forward conduction during negative excursions, potentially damaging the device or circuit. Always match polarity to system bias configuration.
What is the standoff voltage rating of MXLDA3KP9.0AE3 and how should it be applied in circuit design?
The MXLDA3KP9.0AE3 has a reverse standoff voltage (VWM) of 9.0 V, meaning it remains non-conductive up to this DC or peak AC voltage across its terminals. In design, VWM must exceed the maximum continuous operating voltage of the protected line - for example, selecting MXLDA3KP9.0AE3 for a 5 V rail requires verifying that 9.0 V provides sufficient margin above worst-case ripple and tolerance. The MXLDA3KP9.0AE3's 10.0–11.1 V V(BR) range ensures reliable turn-on just above VWM.
Does MXLDA3KP9.0AE3 support MIL-PRF-19500 high-reliability screening?
Yes, MXLDA3KP9.0AE3 qualifies for optional MIL-PRF-19500 upscreening per Microsemi Micronote 129, including wafer lot traceability, 3σ screening on standby current (ID), and full surge testing. This screening is not standard but available upon special order. The base MXLDA3KP9.0AE3 part meets commercial reliability standards; MIL-qualified units carry additional screening codes and documentation required for aerospace and defense programs.
