Product details
Overview
MXLDA3KP13AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 13 V standoff voltage (VWM), 14.4–15.9 V breakdown voltage (V(BR)), and 21.5 V maximum clamping voltage (VC) at 139.4 A peak pulse current (IPP). It provides secondary lightning protection per IEC61000-4-5 (42 Ω, Class 1–4), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in power supply input stages.
For engineers reviewing the MXLDA3KP13AE3 datasheet, MXLDA3KP13AE3 pinout, MXLDA3KP13AE3 application, or MXLDA3KP13AE3 equivalent, this page delivers verified electrical parameters, package dimensions, IEC-compliant surge performance data, polarity marking convention, and RoHS-compliant sourcing details for industrial power interface design and high-reliability embedded systems.
Technical Context
The MXLDA3KP13AE3 operates as a unidirectional avalanche diode-based TVS array, designed for fast-clamping response (<100 ps rise time) to protect downstream circuitry from high-energy transients. Its 13 V rated standoff voltage ensures compatibility with 12 V nominal DC power rails while maintaining margin against normal operating voltage excursions.
It meets MIL-PRF-19500 screening options for high-reliability applications and features wafer-level lot traceability, 3σ standby current (ID) screening, and full surge testing per 10/1000 μs waveform. Moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse working voltage compatible with 12 V system rails |
| V(BR) min/max | 14.4–15.9 V @ 1 mA - guaranteed avalanche conduction onset range for predictable turn-on |
| VC @ IPP | 21.5 V @ 139.4 A - clamping voltage during 10/1000 μs surge, limiting stress on protected ICs |
| PPP | 3000 W @ 10/1000 μs - peak pulse power handling capacity for lightning-induced surges |
| ID @ VWM | 5 μA - ultra-low leakage ensuring minimal standby power loss in always-on circuits |
| TJ/TSTG | −55 to +150 °C - extended temperature range supporting automotive under-hood and industrial control environments |
| RoHS | e3 suffix - lead-free matte-tin plating compliant with EU Directive 2011/65/EU |
Pinout & Package
MXLDA3KP13AE3 uses a 3-pin SMD package (case outline per Page 6 of RF01243 Rev B): void-free UL94V-0 epoxy body, tin-lead or matte-tin terminals, dot-marked Pin 1, odd-numbered pins are cathodes. Polarity follows standard unidirectional TVS convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Anode-side connection point; connects to protected line; cathode ties to ground or lower-potential rail |
| Pin 2 | Anode | Reference node; typically connected to system ground or common return path |
| Pin 3 | Cathode | Second cathode terminal for dual-channel configuration; enables parallel or differential protection layout |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables robust secondary lightning protection per IEC61000-4-5 with 42 Ω source impedance up to Class 4 |
| Clamping response <100 ps | Prevents voltage overshoot before sensitive logic or analog components respond to transients |
| MIL-PRF-19500 screening option | Supports high-reliability aerospace, defense, and critical infrastructure deployments with full lot traceability |
| Moisture Level 1 rating | Eliminates baking requirement prior to reflow, reducing manufacturing cost and process complexity |
| 5 μA max ID @ VWM | Minimizes quiescent current draw in battery-backed or energy-sensitive monitoring circuits |

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 PPP rating, same VWM and VC but lower IPP (53.3 A); DO-214AA package | Not suitable for Class 4 IEC61000-4-5; limited to lower-energy ESD/EFT and switching transients | Select when board space is constrained and surge threat level is Class 1–2 only |
| SMCJ13A | 1500 W PPP, same VWM/VC, IPP = 75.8 A; larger SMC package than MXLDA3KP13AE3 | Lacks MIL-PRF-19500 screening option and moisture Level 1 rating | Choose for cost-sensitive industrial designs where high-reliability screening is not mandated |
Compared with SMBJ13A and SMCJ13A, MXLDA3KP13AE3 uniquely delivers 3000 W pulse capability in a compact 3-pin SMD footprint with military-grade screening readiness and zero dry-pack requirement - making it optimal for mission-critical 12 V power interfaces requiring Class 4 lightning immunity.

FAQ
What is the clamping voltage of MXLDA3KP13AE3 at its rated peak pulse current?
The MXLDA3KP13AE3 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 across the device terminals during standardized surge testing and defines the upper voltage limit imposed on protected circuitry during worst-case transients.
Is MXLDA3KP13AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP13AE3 is RoHS compliant. The 'e3' suffix explicitly denotes matte-tin plating per JEDEC J-STD-609A, confirming compliance with EU Directive 2011/65/EU and absence of lead, cadmium, mercury, hexavalent chromium, PBB, and PBDE substances above threshold limits.
How does the polarity marking work on MXLDA3KP13AE3?
MXLDA3KP13AE3 uses a dot on the top surface to mark Pin 1, and per the datasheet, odd-numbered pins (Pin 1 and Pin 3) are cathodes. Pin 2 is the anode. This unidirectional configuration requires correct orientation during PCB layout - cathodes connect to the line being protected, anode to ground or reference potential.
Can MXLDA3KP13AE3 be used for bidirectional transient suppression?
No - MXLDA3KP13AE3 is a unidirectional TVS device. Bidirectional variants in the same family carry a 'C' suffix (e.g., MDA3KP13CE3). Using MXLDA3KP13AE3 for AC or bipolar signal lines would result in forward conduction during negative half-cycles and potential failure; always select the 'C' version for bidirectional applications.
What is the maximum operating temperature range for MXLDA3KP13AE3?
MXLDA3KP13AE3 is rated for junction and storage temperatures from −55 °C to +150 °C. This extended range supports deployment in under-hood automotive, outdoor telecom equipment, and industrial motor drive environments where ambient temperatures exceed standard commercial limits.
