Product details
Overview
MXLDA3KP13A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection. It features a 13 V reverse standoff voltage (VWM), 14.4–15.9 V breakdown voltage (V(BR)), 21.5 V maximum clamping voltage (VC) at 139.4 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MXLDA3KP13A datasheet, MXLDA3KP13A pinout, MXLDA3KP13A application, or MXLDA3KP13A equivalent, this device serves as a robust, RoHS-compliant TVS for industrial power supplies, telecom line cards, and automotive control modules requiring IEC 61000-4-2/4-4/4-5 compliance with 10/1000 µs surge handling.
Technical Context
The MXLDA3KP13A is a single-channel unidirectional TVS diode optimized for fast clamping response (<100 ps rise time) and high-energy transient suppression. Its 3000 W peak pulse power rating at 10/1000 µs waveform and 21.5 V clamping voltage at 139.4 A ensure reliable overvoltage protection for DC power rails and signal lines exposed to inductive switching or lightning-induced surges.
It complies with IEC 61000-4-5 (secondary lightning, 42 Ω/12 Ω/2 Ω source impedance), IEC 61000-4-2 (ESD ±30 kV air, ±30 kV contact), and IEC 61000-4-4 (EFT 4 kV). The device uses void-free UL94V-0 epoxy packaging with tin-lead or matte-tin terminations and supports MIL-PRF-19500 upscreening options.

IC Role / Device Role / Timing Role: Standoff-rated protector on isolated analog front-end inputs measuring DC bus voltage. Use Value: 13 V VWM matches typical 12 V bias rails; 21.5 V VC prevents saturation of precision op-amps and ADC references. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | 600 W rating, 21.5 V VC @ 27.1 A - lower energy handling than MXLDA3KP13A's 3000 W | Suitable for lighter-duty ESD-only scenarios; not rated for IEC 61000-4-5 Class 4 | Select MXLDA3KP13A when full 3000 W surge immunity is required; SMBJ13A fits space-constrained layouts with lower cost. |
| 1.5KE13A | Through-hole TO-218 package, same 13 V VWM and ~21.2 V VC, but 1500 W rating and slower thermal response | Requires manual or wave soldering; less suitable for high-density SMT production | Choose MXLDA3KP13A for automated SMT lines and higher reliability in harsh thermal cycling environments. |
Compared with SMBJ13A and 1.5KE13A, MXLDA3KP13A delivers triple the surge energy capacity in a surface-mount package with superior thermal derating and MIL-PRF-19500 upscreening support - critical for mission-critical industrial and transportation systems.

FAQ
What is the clamping voltage of MXLDA3KP13A at its rated peak pulse current?
The MXLDA3KP13A has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPP) of 139.4 A under 10/1000 µs waveform conditions. This value is measured per IEC 61000-4-5 test methodology and ensures predictable overvoltage limiting for downstream 12–15 V circuits. The MXLDA3KP13A maintains this clamping performance across its full operating temperature range.
Is MXLDA3KP13A RoHS compliant and what does the 'e3' marking indicate?
Yes, MXLDA3KP13A is RoHS compliant, indicated by the 'e3' suffix in its full marking per Microsemi nomenclature. The 'e3' designation confirms lead-free matte-tin plating on terminations and adherence to EU Directive 2011/65/EU. This applies to both standard and upscreened versions of MXLDA3KP13A, with no exemption required for lead content.
Can MXLDA3KP13A be used for bidirectional transient protection?
No, MXLDA3KP13A is a unidirectional TVS device, as confirmed by its part number structure (no 'C' suffix) and electrical specifications - it conducts only when cathode voltage exceeds anode by ≥14.4 V. For bidirectional protection, Microsemi offers the MXLDA3KP13CA variant, which provides symmetrical clamping for AC-coupled or floating signal lines.
What is the maximum operating temperature range for MXLDA3KP13A?
The MXLDA3KP13A is rated for junction and storage temperatures from –55 °C to +150 °C, verified per Microsemi RF01243 Rev B. This extended range supports deployment in under-hood automotive electronics, industrial motor drives, and outdoor telecom enclosures without derating until ambient exceeds 75 °C, per Figure 3 derating curve.
How does MXLDA3KP13A differ from standard SMBJ-series TVS diodes?
MXLDA3KP13A delivers 3000 W peak pulse power - five times higher than the 600 W rating of SMBJ13A - while sharing identical 13 V VWM and similar 21.5 V clamping voltage. Its DO-214AB package is mechanically identical, but MXLDA3KP13A adds MIL-PRF-19500 upscreening options, tighter parameter distributions, and guaranteed surge testing per lot - distinguishing it as a high-reliability variant.
