Product details
Overview
MXLDA3KP8.0A from Microsemi (now Microchip) is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability overvoltage protection in power rails and signal lines. It features a 8.0 V reverse standoff voltage (VWM), 8.89–9.83 V breakdown voltage (V(BR)), 13.6 V maximum clamping voltage at 220.6 A peak pulse current, and operates across –55 °C to +150 °C junction temperature. It is used in industrial power supplies to protect MOSFET gate drivers from inductive switching transients.
For engineers reviewing the MXLDA3KP8.0A datasheet, MXLDA3KP8.0A pinout, MXLDA3KP8.0A application, or MXLDA3KP8.0A equivalent, key selection criteria include clamping voltage at rated IPP, VWM margin relative to operating voltage, IEC61000-4-5 secondary lightning compliance with 42 Ω source impedance, and RoHS-compliant matte-tin termination compatibility with lead-free reflow.
Technical Context
The MXLDA3KP8.0A implements a silicon avalanche diode structure optimized for sub-100 ps response time and low dynamic impedance under 10/1000 μs surge conditions. Its unidirectional polarity and cathode-defined pin 1 enable precise placement in DC-biased protection paths.
It meets MIL-PRF-19500 screening options for high-reliability applications and is surge-tested per JEDEC JESD22-A114E for ESD immunity up to ±30 kV (contact). Clamping performance is characterized at 25 °C with derating above 25 °C per Figure 3.

Pinout & Package
MXLDA3KP8.0A uses a 3-pin TO-277A (SMB) surface-mount package with void-free UL94V-0 epoxy body and matte-tin-plated terminals. Pin 1 is cathode, marked by a dot on top of the package; odd-numbered pins are cathodes per device channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line side; clamps positive transients to ground when forward-biased |
| Pin 2 | Anode | Connected to ground or low-impedance return path; completes clamping current loop |
| Pin 3 | Cathode | Second independent TVS channel cathode; enables dual-rail or differential protection |
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 | Lower PPP (400 W), higher VC (12.0 V @ 32.4 A), same VWM and package | Not suitable for IEC61000-4-5 Class 4; limited to lower-energy ESD/EFT only | Select SMAJ8.0A only where surge energy is <500 W and layout space is constrained |
| SMCJ8.0A | Same PPP (3000 W), identical VWM and VC, but larger DO-214AB package (7.11 mm × 6.22 mm) | Requires PCB footprint redesign; better thermal dissipation in high-ambient environments | Choose SMCJ8.0A when board-level thermal management exceeds SMB limits or legacy designs use DO-214AB |
Compared with SMAJ8.0A and SMCJ8.0A, the MXLDA3KP8.0A delivers identical 3000 W surge capability in the smaller TO-277A footprint while maintaining 50 μA standby leakage-critical for battery-backed or low-quiescent systems where leakage directly impacts runtime.

FAQ
What is the maximum clamping voltage of the MXLDA3KP8.0A at its rated peak pulse current?
The MXLDA3KP8.0A 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 measured per JEDEC test standards and ensures predictable voltage limiting during surge events. The MXLDA3KP8.0A maintains this clamping performance across its full operating temperature range, with derating applied above 25 °C per the manufacturer's published curve.
Is the MXLDA3KP8.0A RoHS compliant and what does the 'e3' marking indicate?
Yes, the MXLDA3KP8.0A is RoHS compliant, indicated by the 'e3' suffix in its marking per Microsemi's nomenclature. The 'e3' denotes annealed matte-tin plating meeting JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required-and full compliance with Directive 2011/65/EU. The MXLDA3KP8.0A supports lead-free reflow profiles up to 260 °C for 10 seconds without degradation.
Can the MXLDA3KP8.0A be used for bidirectional transient suppression?
No, the MXLDA3KP8.0A is a unidirectional TVS device, as confirmed by its part number structure (no 'C' suffix) and electrical characterization showing forward clamping only. For bidirectional protection, Microsemi specifies variants such as MXLDA3KP8.0CA. Using the MXLDA3KP8.0A in AC-coupled or floating applications without proper DC biasing may result in unintended conduction or failure to clamp negative transients.
What is the standoff voltage rating and how does it relate to system operating voltage?
MXLDA3KP8.0A has a rated reverse standoff voltage (VWM) of 8.0 V, meaning it remains non-conductive up to this DC or peak AC voltage across its operating temperature range. System operating voltage must be ≤ VWM to avoid leakage or thermal runaway; for a nominal 5 V rail, MXLDA3KP8.0A provides ~60% margin, aligning with Microsemi's recommendation that VWM ≥ 1.2× peak operating voltage. The MXLDA3KP8.0A achieves this with only 50 μA max ID at 8.0 V.
Does the MXLDA3KP8.0A require special handling or packaging due to moisture sensitivity?
No, the MXLDA3KP8.0A is rated IPC/JEDEC J-STD-020B Level 1 (unlimited floor life), meaning it does not require dry pack, baking, or humidity-controlled storage. Its void-free thermosetting epoxy body and matte-tin terminations ensure robustness through standard SMT reflow. This eliminates process steps and yield loss associated with moisture-sensitive devices, making the MXLDA3KP8.0A suitable for high-volume automated assembly without special handling protocols.
