Product details
Overview
MXLDA3KP8.0AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 8.0 V standoff voltage (VWM), 8.89–9.83 V breakdown voltage (V(BR)), and 13.6 V clamping voltage (VC) at 220.6 A peak pulse current, designed for secondary lightning protection per IEC61000-4-5 and ESD/EFT suppression per IEC61000-4-2/4-4 in industrial power interfaces.
For engineers reviewing the MXLDA3KP8.0AE3 datasheet, MXLDA3KP8.0AE3 pinout, MXLDA3KP8.0AE3 application, or MXLDA3KP8.0AE3 equivalent, key selection criteria include its 8.0 V working voltage, 13.6 V clamping performance at 220.6 A, RoHS-compliant e3 marking, unidirectional polarity, and MIL-PRF-19500 upscreening capability for high-reliability deployments.
Technical Context
The MXLDA3KP8.0AE3 operates as a unidirectional avalanche diode-based TVS array, delivering sub-100 ps response time to clamp transients before sensitive circuitry sustains damage. Its 3000 W peak pulse power rating is validated at 10/1000 µs waveform with ≤0.05% duty factor, and it maintains stable clamping across -55 °C to +150 °C junction temperature range.
Designed for vertical mounting on PCBs, the device uses void-free UL94V-0 epoxy packaging with tin-lead or matte-tin terminations compliant with MIL-STD-750 Method 2026. Pin 1 is cathode-defined by a dot marking, and odd-numbered pins serve as cathodes per TVS element in multi-channel configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous reverse operating voltage before conduction begins; matches nominal 5–8 V DC bus levels. |
| V(BR) min/max | 8.89–9.83 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on margin above VWM. |
| VC @ IPP | 13.6 V - Clamping voltage at 220.6 A peak pulse; limits downstream voltage stress during surge events. |
| IPP | 220.6 A - Peak impulse current supported at 10/1000 µs waveform; defines maximum surge energy absorption. |
| ID @ VWM | 50 µA - Standby leakage at rated standoff voltage; low enough to avoid system power drain in always-on circuits. |
| TJ/TSTG | -55 to +150 °C - Full industrial and extended temperature operation without derating up to 125 °C ambient. |
| PPP | 3000 W - Peak pulse power handling at 10/1000 µs; enables robust protection against lightning-induced surges. |
Pinout & Package
Package: Surface-mount vertical TO-277A (3-pin single-row) with void-free UL94V-0 epoxy body, ~5 g weight, and moisture sensitivity level 1 (no dry pack required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Marked by dot; connects to protected line's return path or ground reference for unidirectional clamping. |
| Pin 2 | Anode | Common anode node shared across all TVS elements; ties to system ground plane for low-inductance surge shunting. |
| Pin 3 | Cathode | Second cathode terminal; used for dual-line protection or parallel configuration to increase current capacity. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | 600 W PPP rating, SMA package, 13.6 V VC at 48.4 A IPP - lower surge capacity and smaller thermal mass. | Best suited for consumer-grade, low-energy ESD-only protection; insufficient for IEC61000-4-5 Class 3+. | Select MXLDA3KP8.0AE3 when 3000 W surge handling and MIL-qualified reliability are required. |
| SMCJ8.0A | 1500 W PPP rating, SMC package, 13.6 V VC at 110 A IPP - half the peak power and current capacity of MXLDA3KP8.0AE3. | Appropriate for mid-tier industrial controls where cost constraints outweigh extreme surge margin needs. | Choose MXLDA3KP8.0AE3 for mission-critical infrastructure where full 3000 W compliance and vertical mounting are mandatory. |
Compared with SMAJ8.0A and SMCJ8.0A, MXLDA3KP8.0AE3 delivers double the peak pulse power and current capacity in a vertical-mount package optimized for high-reliability systems, enabling direct replacement only when board layout accommodates TO-277A footprint and thermal mass requirements.

FAQ
What is the clamping voltage of MXLDA3KP8.0AE3 at its rated peak pulse current?
The MXLDA3KP8.0AE3 has a maximum clamping voltage (VC) of 13.6 V at its rated peak pulse current (IPP) of 220.6 A under 10/1000 µs waveform conditions. This value is guaranteed across the full operating temperature range and ensures downstream circuitry remains within safe voltage limits during surge events. The MXLDA3KP8.0AE3 achieves this clamping performance while maintaining low leakage and fast response time.
Is MXLDA3KP8.0AE3 RoHS-compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP8.0AE3 is RoHS-compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide. The 'e3' designation specifies matte-tin plating and halogen-free epoxy encapsulation meeting EU Directive 2011/65/EU. This compliance applies to both termination finish and package materials, and MXLDA3KP8.0AE3 requires no special handling or dry packing due to its IPC/JEDEC J-STD-020B Level 1 moisture sensitivity rating.
How does MXLDA3KP8.0AE3 differ from bidirectional variants like MXLDA3KP8.0CE3?
MXLDA3KP8.0AE3 is unidirectional, meaning it conducts only during reverse-voltage transients and blocks forward current, making it ideal for DC-biased lines. In contrast, MXLDA3KP8.0CE3 is bidirectional and symmetrical, conducting during both polarities - suitable for AC signal lines or floating buses. The MXLDA3KP8.0AE3's unidirectional design yields tighter V(BR) tolerance and lower leakage, while MXLDA3KP8.0CE3 provides balanced clamping but higher standby current.
Can MXLDA3KP8.0AE3 be used for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MXLDA3KP8.0AE3 is rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, as documented in the RF01243 datasheet. Its 3000 W peak pulse power and 220.6 A IPP capability meet the 4 kV open-circuit voltage requirement for Class 4. The MXLDA3KP8.0AE3 must be mounted with low-inductance grounding and appropriate PCB layout to maintain this rating in end equipment.
What is the thermal derating behavior of MXLDA3KP8.0AE3 above 25 °C ambient?
MXLDA3KP8.0AE3 follows a linear derating curve starting at 25 °C, reducing peak pulse power by approximately 1.25% per °C rise in case temperature, down to zero power at +150 °C junction temperature. This derating is defined in Figure 3 of the RF01243 datasheet and applies to continuous surge repetition; single-event capability remains intact. For sustained high-temperature operation, MXLDA3KP8.0AE3 requires adequate copper pour and thermal vias to maintain TJ ≤ 125 °C.
