Product details
Overview
MXLDA3KP12AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 12 V standoff voltage (VWM), 13.3–14.7 V breakdown voltage (V(BR)), and 19.9 V maximum clamping voltage (VC) at 150.6 A peak pulse current (IPP). It delivers sub-100 ps response time and operates across –55 °C to +150 °C for secondary lightning protection in telecom power interfaces.
For engineers reviewing the MXLDA3KP12AE3 datasheet, MXLDA3KP12AE3 pinout, MXLDA3KP12AE3 application, or MXLDA3KP12AE3 equivalent, key selection criteria include VWM matching system DC rail, VC margin relative to protected IC absolute maximum ratings, IPP derating at elevated ambient temperature, and RoHS-compliant matte-tin terminations for lead-free reflow compatibility.
Technical Context
This TVS array uses silicon avalanche diode technology optimized for high-energy transients under 10/1000 µs waveform conditions. Its unidirectional polarity enables asymmetric clamping-low forward surge voltage (4.0 V @ 500 A) and fast turn-on during positive overvoltage events on grounded-line configurations.
Designed for IEC61000-4-5 Class 1–4 secondary lightning protection with 42 Ω, 12 Ω, or 2 Ω source impedances, it meets MIL-PRF-19500 screening options when upscreened and maintains Level 1 moisture sensitivity without dry pack per J-STD-020B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12 V - Maximum continuous DC or peak AC voltage applied without triggering conduction |
| V(BR) min/max | 13.3–14.7 V @ 1 mA - Ensures reliable turn-on above normal operating voltage while avoiding false triggering |
| VC @ IPP | 19.9 V @ 150.6 A - Clamped voltage seen by downstream circuitry during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - Peak power dissipation capability defining surge energy handling limit |
| ID @ VWM | 5 µA - Leakage current at rated standoff voltage, critical for low-power standby circuits |
| Response time | <100 ps - Enables effective suppression of ESD (IEC61000-4-2) and EFT (IEC61000-4-4) |
Pinout & Package

FAQ
What is the clamping voltage of MXLDA3KP12AE3 at its rated peak pulse current?
The MXLDA3KP12AE3 has a maximum clamping voltage (VC) of 19.9 V at its rated peak pulse current (IPP) of 150.6 A under 10/1000 µs waveform conditions. This value ensures protected downstream components remain within their absolute maximum voltage ratings during surge events. The MXLDA3KP12AE3 achieves this clamping performance while maintaining low leakage (<5 µA at 12 V) and sub-100 ps response time.
Is MXLDA3KP12AE3 RoHS compliant and compatible with lead-free reflow processes?
Yes, MXLDA3KP12AE3 carries the e3 suffix, indicating RoHS-compliant matte-tin plating on its terminations. It is qualified for soldering at 260 °C for 10 seconds per MIL-STD-750 Method 2026, making it fully compatible with standard Pb-free reflow profiles. The MXLDA3KP12AE3 also meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity, eliminating the need for dry pack storage or pre-bake.
How does MXLDA3KP12AE3 support IEC61000-4-5 secondary lightning protection?
MXLDA3KP12AE3 supports IEC61000-4-5 Class 1–4 secondary lightning protection with source impedances of 42 Ω, 12 Ω, and 2 Ω. Its 3000 W peak pulse power rating and 150.6 A IPP enable it to clamp 4 kV line-to-ground surges per Class 4 requirements. The MXLDA3KP12AE3's specified VC of 19.9 V ensures protected circuits remain within safe operating limits during these standardized tests.
What is the polarity configuration and pin assignment of MXLDA3KP12AE3?
MXLDA3KP12AE3 is a unidirectional TVS array with two independent channels. Pin 1 and Pin 3 are cathodes; Pin 2 and Pin 4 are anodes. Polarity follows the convention that odd-numbered pins are cathodes, and Pin 1 is marked by a dot on the package top surface. This configuration allows flexible implementation across single-ended or dual-rail protection schemes in the MXLDA3KP12AE3 layout.
Can MXLDA3KP12AE3 be used for ESD and EFT protection per IEC61000-4-2 and IEC61000-4-4?
Yes, MXLDA3KP12AE3 is explicitly rated for ESD protection per IEC61000-4-2 and EFT protection per IEC61000-4-4 due to its <100 ps response time and low clamping voltage. Its fast turn-on characteristic ensures effective suppression of 8 kV contact and 15 kV air discharge events. The MXLDA3KP12AE3 delivers consistent performance across temperature and lifetime, validated by 3σ lot norm screening on standby current (ID).
