Product details
Overview
MXLDA3KP6.0A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 6.0 V standoff voltage (VWM), 6.67–7.37 V breakdown voltage (V(BR)), and 10.3 V clamping voltage (VC) at 291.3 A peak pulse current, designed for secondary lightning protection per IEC61000-4-5 in telecom power interfaces.
For engineers reviewing the MXLDA3KP6.0A datasheet, MXLDA3KP6.0A pinout, MXLDA3KP6.0A application, or MXLDA3KP6.0A equivalent, key selection criteria include its 10.3 V clamping performance at 291.3 A, -55°C to +150°C operating junction temperature, RoHS-compliant void-free epoxy package, and compliance with MIL-PRF-19500 high-reliability screening options.
Technical Context
The MXLDA3KP6.0A operates as a unidirectional avalanche diode-based TVS, triggered when reverse voltage exceeds its 6.67–7.37 V breakdown range. It delivers sub-100 ps response time and clamps transients to ≤10.3 V under 10/1000 μs waveform at 291.3 A, meeting IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and IEC61000-4-5 (lightning) immunity requirements.
Its design supports secondary lightning protection across Class 1–4 with 42 Ω source impedance and Class 1–3 with 12 Ω source impedance per IEC61000-4-5. Standby leakage remains ≤1000 μA at 6.0 V VWM, and it withstands soldering up to 260°C for 10 s.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | 600 W PPP rating, 10.3 V VC @ 43.5 A, DO-214AC package | Limited to lower-energy transients; unsuitable for IEC61000-4-5 Class 4 with 42 Ω source | Select MXLDA3KP6.0A when 3000 W surge handling and MIL-PRF-19500 screening are required. |
| SMCJ6.0A | 1500 W PPP rating, 10.3 V VC @ 145 A, DO-214AB package | Half the peak power capacity; insufficient for sustained secondary lightning events | MXLDA3KP6.0A provides double the surge margin and wider temperature range (-55°C to +150°C vs. -65°C to +150°C). |
Compared with SMAJ6.0A and SMCJ6.0A, MXLDA3KP6.0A delivers 2× and 2× higher peak pulse power respectively, enabling single-device compliance with IEC61000-4-5 Class 4 lightning testing where lower-rated alternatives require parallel staging or derating.

FAQ
What is the clamping voltage of the MXLDA3KP6.0A at its rated peak pulse current?
The MXLDA3KP6.0A has a maximum clamping voltage (VC) of 10.3 V at its rated peak pulse current (IPP) of 291.3 A under 10/1000 μs waveform conditions. This value is measured per IEC61000-4-5 test methodology and ensures downstream circuitry remains below safe voltage thresholds during surge events. The MXLDA3KP6.0A maintains this clamping performance across its full operating temperature range.
Is the MXLDA3KP6.0A RoHS compliant and what marking indicates compliance?
Yes, the MXLDA3KP6.0A is RoHS compliant, indicated by the "e3" suffix in its full marking per Microsemi's nomenclature. This denotes annealed matte-tin plating and absence of lead, cadmium, mercury, hexavalent chromium, PBB, and PBDE substances. Compliance is verified per JEDEC J-STD-609A and aligns with EU Directive 2011/65/EU. The MXLDA3KP6.0A meets these requirements without derating or process modification.
Does the MXLDA3KP6.0A support MIL-PRF-19500 high-reliability screening?
Yes, optional MIL-PRF-19500 screening is available for the MXLDA3KP6.0A, including wafer lot traceability, 3σ screening on standby current (ID), and conformance inspections per Microsemi Micronote 129. This screening is not standard but can be specified at order entry. The MXLDA3KP6.0A's base construction already includes high-reliability features such as void-free epoxy encapsulation and 260°C solder tolerance.
What is the maximum standoff voltage and how does it relate to system operating voltage?
The MXLDA3KP6.0A has a rated working standoff voltage (VWM) of 6.0 V - the maximum continuous reverse voltage it blocks without significant conduction. System operating voltage must be ≤ VWM to prevent premature leakage or thermal runaway; for example, it is suited for 5 V logic rails or 6 V sensor supplies. The MXLDA3KP6.0A's 6.67–7.37 V breakdown range ensures margin above VWM while maintaining fast response.
How does the MXLDA3KP6.0A perform under IEC61000-4-5 secondary lightning testing?
The MXLDA3KP6.0A is certified for secondary lightning protection per IEC61000-4-5 across Class 1–4 with 42 Ω source impedance and Class 1–3 with 12 Ω source impedance. Its 3000 W peak pulse power rating directly supports the 4 kV/2 Ω and 2 kV/12 Ω test levels. The MXLDA3KP6.0A achieves this with ≤10.3 V clamping and no degradation after multiple surges, validated per Figure 1 and Table 1 in RF01243 Rev B.
