Product details
Overview
MXLDA3KP10A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 10 V standoff voltage (VWM), 11.1–12.3 V breakdown voltage (V(BR)), and 17.0 V clamping voltage (VC) at 176.4 A peak pulse current. It protects voltage-sensitive circuits from ESD, EFT, inductive switching transients, and secondary lightning surges per IEC61000-4-2/4-4/4-5.
For engineers reviewing the MXLDA3KP10A datasheet, MXLDA3KP10A pinout, MXLDA3KP10A application, or MXLDA3KP10A equivalent, this device serves as a high-reliability, RoHS-compliant TVS for industrial power supplies, telecom interfaces, and automotive control modules requiring robust 10/1000 µs surge immunity up to 3 kW.
Technical Context
The MXLDA3KP10A operates as a unidirectional avalanche diode-based clamp, activated when reverse voltage exceeds its 11.1 V minimum breakdown threshold. Its sub-100 ps response time enables effective suppression of ESD events per IEC61000-4-2 and fast transients per IEC61000-4-4.
It is rated for 3000 W peak pulse power at 10/1000 µs waveform, with 5 µA maximum standby current at 10 V and junction temperature range of –55 °C to +150 °C - supporting operation in harsh environments including under-hood automotive and outdoor telecom infrastructure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping begins |
| V(BR) min/max | 11.1–12.3 V @ 1 mA - defines precise avalanche onset window for predictable turn-on behavior |
| VC @ IPP | 17.0 V @ 176.4 A - clamping voltage during full 3 kW surge, limiting downstream stress |
| IPP | 176.4 A - peak impulse current supported at 10/1000 µs waveform |
| ID @ VWM | 5 µA - ultra-low leakage ensures minimal power loss in standby mode |
| PPP | 3000 W - peak pulse power rating confirming suitability for Class 3/4 secondary lightning protection |
| TJ/TSTG | –55 °C to +150 °C - wide thermal range supports deployment in extended-temperature industrial and automotive applications |
Pinout & Package
MXLDA3KP10A uses a 3-pin surface-mount package with cathode-defined polarity: Pin 1 and Pin 3 are cathodes; Pin 2 is the common anode. The void-free thermosetting epoxy case meets UL94V-0, and marking includes date code and part number with Pin 1 identified by a dot on top.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connects to protected line; conducts during overvoltage to shunt energy to ground |
| Pin 2 | Common Anode | Shared anode node tied to system ground or low-impedance return path |
| Pin 3 | Cathode of Channel 2 | Second protected line terminal; enables dual-line or differential-mode protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | 600 W PPP rating, same VWM and unidirectional polarity, but lower IPP (101 A) and higher VC (17.0 V vs. 17.0 V - identical) | Limited to Class 2 lightning protection; insufficient for IEC61000-4-5 Class 3/4 with 42 Ω source | Select SMBJ10A only for space-constrained designs where 3 kW surge headroom is not required. |
| SMCJ10A | 1500 W PPP, same VWM, 11.1–12.3 V V(BR), 17.0 V VC, but IPP = 88.2 A - half that of MXLDA3KP10A | Valid for Class 2 lightning only; cannot meet 176.4 A surge demand of high-energy industrial systems | Choose SMCJ10A when cost sensitivity outweighs need for full 3 kW capability and board area permits larger footprint than MXLDA3KP10A. |
Compared with SMBJ10A and SMCJ10A, the MXLDA3KP10A delivers double the pulse power handling and peak current capacity - enabling single-device compliance with stringent IEC61000-4-5 Class 4 requirements where alternatives require parallel staging or derating.

FAQ
What is the clamping voltage of MXLDA3KP10A at its rated peak pulse current?
The MXLDA3KP10A has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPP) of 176.4 A under 10/1000 µs waveform conditions. This value is measured per Figure 2 in the official datasheet and ensures downstream circuitry remains within safe voltage limits during worst-case surge events. The MXLDA3KP10A maintains this clamping performance across its full operating temperature range.
Is MXLDA3KP10A RoHS compliant and what does the 'e3' marking indicate?
Yes, MXLDA3KP10A is RoHS compliant, indicated by the 'e3' suffix in its marking per Microsemi's nomenclature guide. The 'e3' denotes annealed matte-tin plating meeting JEDEC J-STD-020B Level 1 moisture sensitivity - eliminating dry-pack requirements and supporting standard Pb-free reflow profiles. This compliance is verified per the RF01243 Rev B datasheet and applies to all units shipped post-2019.
How many protected lines does MXLDA3KP10A support and how is polarity configured?
MXLDA3KP10A supports two independent protected lines via a dual-cathode configuration: Pin 1 and Pin 3 serve as cathodes for separate channels, while Pin 2 is the common anode. Polarity is unidirectional, meaning it clamps only reverse-voltage transients - ideal for DC-biased signal or power lines. This layout is confirmed in the "MECHANICAL and PACKAGING" section and pad layout diagram of the MXLDA3KP10A datasheet.
Does MXLDA3KP10A meet IEC61000-4-5 Class 4 lightning protection requirements?
Yes, MXLDA3KP10A meets IEC61000-4-5 Class 4 secondary lightning protection when tested with 42 Ω source impedance, as explicitly stated in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse power and 176.4 A IPP rating satisfy the 4 kV test level requirement. Performance is validated across temperature and lot traceability supports qualification for high-reliability deployments.
What is the maximum standby leakage current of MXLDA3KP10A at its rated standoff voltage?
The MXLDA3KP10A exhibits a maximum standby current (ID) of 5 µA at its rated reverse standoff voltage (VWM) of 10 V, measured at 25 °C. This ultra-low leakage minimizes quiescent power loss in battery-backed or energy-sensitive systems. The value is specified in the Electrical Characteristics table on page 3 of the RF01243 Rev B datasheet and holds across the full –55 °C to +150 °C operating junction temperature range.
