Product details
Overview
MXLDA3KP13CA from Microsemi is a bidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for secondary lightning and ESD/EFT protection in industrial power interfaces. It features a 13 V reverse standoff voltage (VWM), 14.4–15.9 V breakdown voltage (V(BR)), 21.5 V maximum clamping voltage at 139.4 A peak pulse current, and operates from –55 °C to +150 °C. Used in AC/DC front-end surge protection circuits.
For engineers reviewing the MXLDA3KP13CA datasheet, MXLDA3KP13CA pinout, MXLDA3KP13CA application, or MXLDA3KP13CA equivalent, key selection criteria include bidirectional polarity, 10/1000 µs surge rating, IEC61000-4-2/4-4/4-5 compliance, thermal derating above 25 °C, and compatibility with 2.54 mm pitch PCB layouts per documented pad dimensions.
Technical Context
This TVS array uses silicon avalanche diode technology to clamp transient overvoltages within nanoseconds. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal/power lines without polarity sensitivity.
It delivers 3000 W peak pulse power at 10/1000 µs waveform with <5 ns response time, supports MIL-PRF-19500 upscreening options, and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous operating voltage before clamping begins; sets minimum system working voltage margin. |
| V(BR) min/max | 14.4–15.9 V @ 1 mA - Confirmed avalanche onset range; ensures predictable turn-on across temperature and lot variation. |
| VC @ IPP | 21.5 V @ 139.4 A - Clamped voltage during worst-case 10/1000 µs surge; defines protected circuit's maximum stress level. |
| PPP | 3000 W @ 10/1000 µs - Peak transient energy handling capacity; validated per Figure 1 derating curve. |
| TJ/TSTG | –55 °C to +150 °C - Full industrial temperature range operation; supports under-hood or high-ambient embedded systems. |
| ID @ VWM | 5 µA max - Low leakage at rated standoff; minimizes standby power loss in always-on protection paths. |
| Polarity | Bidirectional - Enables use on AC lines or differential buses without orientation constraints. |
Pinout & Package
MXLDA3KP13CA is housed in a void-free thermosetting epoxy package (UL94V-0) with tin-lead or matte-tin plating. Pin 1 is marked by a dot on top; odd-numbered pins are cathodes per device channel. Weight ≈ 5 g. Dimensions match standard 2-pin SMD layout per Page 6 drawing (A = 21.03–22.05 mm, B = 6.86–7.87 mm, C = 8.64–9.65 mm, D = 2.54 mm typ).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Reference terminal for bidirectional clamping; connects to protected line side in series configuration. |
| Pin 2 | Anode of Channel 1 | Common return path; ties to ground or reference rail; forms symmetrical clamping path with Pin 1. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | 600 W PPP rating, same VWM and bidirectional polarity, but lower clamping voltage (21.5 V vs. 21.5 V) and smaller SMB package. | Lower energy handling limits use to sub-100 A surge environments; unsuitable for IEC61000-4-5 Class 4. | Select when board space is constrained and peak surge current remains below 43 A. |
| SMCJ13CA | 1500 W PPP rating, identical VWM and polarity, larger SMC package, clamping voltage 21.5 V at 70 A. | Meets Class 3 lightning but not Class 4; requires larger PCB footprint than MXLDA3KP13CA. | Choose for cost-sensitive designs where 1500 W surge capability suffices and thermal mass is adequate. |
Compared with SMBJ13CA and SMCJ13CA, MXLDA3KP13CA delivers double the surge energy capacity of SMCJ13CA and five times that of SMBJ13CA while maintaining identical 13 V standoff and bidirectional symmetry-enabling fewer devices per rail in high-reliability industrial power systems.

FAQ
What is the polarity configuration of MXLDA3KP13CA?
MXLDA3KP13CA is a bidirectional TVS device, indicated by the "C" suffix in its part number. This allows symmetrical clamping for both positive and negative transients without regard to installation orientation-ideal for AC lines, differential data buses, or floating grounds where polarity cannot be guaranteed during system operation or maintenance.
Does MXLDA3KP13CA meet IEC61000-4-5 Class 4 requirements?
Yes, MXLDA3KP13CA meets IEC61000-4-5 Class 4 for secondary lightning protection when tested with a 42 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse power rating and 21.5 V clamping voltage ensure compliance under the full 4 kV test waveform.
What is the maximum clamping voltage of MXLDA3KP13CA and at what current?
The maximum clamping voltage VC of MXLDA3KP13CA is 21.5 V, measured at its peak pulse current IPP of 139.4 A under 10/1000 µs waveform conditions. This value is specified in the Electrical Characteristics table on Page 3 of the RF01243 datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Is MXLDA3KP13CA RoHS compliant?
Yes, MXLDA3KP13CA is RoHS compliant, as indicated by the "e3" suffix in its full marking per Page 2 of RF01243. The "e3" designation confirms annealed matte-tin plating and lead-free construction meeting EU Directive 2011/65/EU requirements without exemption claims.
What package type does MXLDA3KP13CA use and what are its key mechanical features?
MXLDA3KP13CA uses a void-free transfer-molded thermosetting epoxy case meeting UL94V-0 flammability rating. Terminals feature tin-lead or matte-tin plating per MIL-STD-750 Method 2026. Pin 1 is marked by a dot, odd pins are cathodes, and weight is approximately 5 grams-dimensions align with standardized 2-pin SMD layout per Page 6 mechanical drawing.
