Product details
Overview
MXLDA3KP6.0AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 6.0 V reverse standoff voltage (VWM), 6.67–7.37 V breakdown voltage (V(BR)), and 10.3 V maximum clamping voltage (VC) at 291.3 A peak pulse current. 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 inputs and telecom interfaces.
For engineers reviewing the MXLDA3KP6.0AE3 datasheet, MXLDA3KP6.0AE3 pinout, MXLDA3KP6.0AE3 application, or MXLDA3KP6.0AE3 equivalent, key selection criteria include VWM matching system DC rail, VC margin relative to protected IC's absolute maximum rating, 10/1000 µs surge capability, RoHS-compliant e3 plating, and MIL-PRF-19500 upscreening eligibility for high-reliability deployments.
Technical Context
The MXLDA3KP6.0AE3 operates as a unidirectional avalanche diode-based TVS, designed for fast clamping (<100 ps response) during transient overvoltage events. Its silicon junction structure enables low dynamic impedance under 3000 W 10/1000 µs surges while maintaining ≤10.3 V clamping at 291.3 A IPP.
It is rated for -55 °C to +150 °C junction temperature, features void-free UL94V-0 epoxy packaging, tin-lead or matte-tin (e3) terminations, and polarity defined by odd-numbered pins as cathodes - consistent with its 3-pin SMD package layout and MDA series mechanical standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous DC or peak AC voltage the device blocks without conduction; must exceed system operating rail. |
| V(BR) min/max | 6.67–7.37 V @ I(BR) - Voltage at which avalanche breakdown begins; defines turn-on threshold tolerance band. |
| VC @ IPP | 10.3 V @ 291.3 A - Clamped voltage seen by downstream circuitry during worst-case 10/1000 µs surge; determines protection margin. |
| PPP | 3000 W @ 10/1000 µs - Peak transient energy handling capacity; validates compliance with IEC61000-4-5 Class 4 (42 Ω source). |
| ID @ VWM | 1000 µA - Standby leakage at rated standoff; impacts low-power system quiescent current budget. |
| TJ/TSTG | -55 to +150 °C - Operating and storage temperature range; supports industrial and aerospace thermal environments. |
Pinout & Package
MXLDA3KP6.0AE3 uses a 3-pin surface-mount package with void-free UL94V-0 epoxy body, matte-tin (e3) terminations, and polarity marked by a dot indicating Pin 1. Odd-numbered pins are cathodes; Pin 1 = Cathode, Pin 2 = Anode, Pin 3 = Cathode - forming dual common-cathode configuration for bidirectional-capable layout (though this part is unidirectional per suffix 'A').
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Common cathode connection for first TVS element; ties to system ground or reference plane in clamp-to-rail topology. |
| Pin 2 | Anode | Input/anode node for transient path; connects to protected line (e.g., DC input, RS-485 bus, PoE feed). |
| Pin 3 | Cathode | Common cathode for second TVS element; electrically tied to Pin 1 internally or externally for dual-line protection. |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W 10/1000 µs surge rating | Validates robustness against IEC61000-4-5 secondary lightning surges up to Class 4 with 42 Ω source impedance. |
| Clamping voltage ≤10.3 V @ 291.3 A | Ensures protected ICs with 12 V absolute max rating (e.g., LDOs, transceivers) remain within safe operating limits. |
| e3 RoHS-compliant matte-tin plating | Enables lead-free reflow assembly without solderability degradation or whisker risk in long-life systems. |
| MIL-PRF-19500 upscreening option | Supports high-reliability qualification for defense/aerospace applications via wafer lot traceability and 3σ ID screening. |
Applications
| DC Power Input Protection | Telecom Line Interface |
|---|---|
Use Scenario: 12 V DC input rail of industrial PLC controller exposed to load dump and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS clamping transient energy to ground before it reaches upstream DC-DC converter and microcontroller. Use Value: Limits voltage excursion to ≤10.3 V during 3000 W surges, preventing latch-up or gate oxide damage in 12 V-rated power management ICs. | Use Scenario: RS-485 data lines in building automation node subjected to EFT bursts and nearby lightning-induced coupling. IC Role / Device Role / Timing Role: Fast-response TVS shunting EFT energy (IEC61000-4-4) and ESD (IEC61000-4-2) away from transceiver I/O pins. Use Value: Sub-100 ps response ensures clamping initiates before transceiver input stage sustains cumulative stress from repetitive 5 kHz burst trains. |
| Secondary Lightning Protection | Automotive Body Control Module |
Use Scenario: 24 V CAN bus interface in railway signaling cabinet requiring IEC61000-4-5 Class 3 immunity (12 Ω source). IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing 4 kV/2 kA surge energy while holding line voltage below transceiver breakdown threshold. Use Value: 6.0 V VWM allows use on 5 V logic rails; 10.3 V VC ensures compatibility with 15 V tolerant CAN FD transceivers. | Use Scenario: Low-voltage sensor supply line (5 V) in automotive BCM exposed to ISO 7637-2 pulse 1/2a/5a transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp protecting linear regulators and ADC front-ends from battery reversal and alternator load dump. Use Value: 1000 µA ID at VWM minimizes impact on 5 V rail quiescent current; -55 °C to +150 °C rating covers under-hood thermal extremes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | 600 W PPP rating, SMA package, 10.5 V VC @ 43.5 A IPP - lower surge capacity and higher clamping than MXLDA3KP6.0AE3. | Best suited for consumer-grade 12 V USB-C PD protection where 3000 W is unnecessary. | Select SMAJ6.0A only when board space is constrained and surge threat level is limited to IEC61000-4-4 EFT, not lightning. |
| SMCJ6.0A | 1500 W PPP, SMC package, 10.3 V VC @ 146 A IPP - half the surge rating but same clamping voltage and compatible footprint. | Appropriate for mid-tier industrial I/O modules needing Class 2 lightning immunity (42 Ω, 2 kV) without full Class 4 margin. | Choose SMCJ6.0A when cost sensitivity outweighs need for 3000 W headroom and MIL-PRF-19500 screening is not required. |
Compared with SMAJ6.0A and SMCJ6.0A, MXLDA3KP6.0AE3 delivers double the surge power handling of SMCJ6.0A and five times that of SMAJ6.0A while maintaining identical clamping performance - making it the only choice for mission-critical 42 Ω IEC61000-4-5 Class 4 compliance and high-reliability upscreening.

FAQ
What is the clamping voltage specification for MXLDA3KP6.0AE3 under maximum surge conditions?
The MXLDA3KP6.0AE3 has a maximum clamping voltage (VC) of 10.3 V at 291.3 A peak pulse current (IPP), measured under standardized 10/1000 µs waveform conditions. This value represents the upper limit of voltage imposed on the protected circuit during worst-case transient events and is critical for ensuring downstream components remain within their absolute maximum voltage ratings. The MXLDA3KP6.0AE3 achieves this clamping performance while sustaining 3000 W peak pulse power, distinguishing it from lower-rated TVS devices.
Is MXLDA3KP6.0AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP6.0AE3 is RoHS compliant, as confirmed by the 'e3' suffix in its part number. Per Microsemi's nomenclature, 'e3' denotes matte-tin plating that meets EU RoHS Directive 2011/65/EU requirements and is qualified for lead-free reflow soldering per IPC/JEDEC J-STD-020B Level 1 (no dry pack required). The MXLDA3KP6.0AE3 also complies with JEDEC moisture sensitivity level 1, supporting standard SMT assembly processes without baking preconditioning.
Can MXLDA3KP6.0AE3 be used for bidirectional transient suppression?
No, MXLDA3KP6.0AE3 is a unidirectional TVS, indicated by the absence of 'C' in its part number suffix (e.g., MDA3KP6.0CA would be bidirectional). Its electrical behavior is optimized for clamping positive transients to ground, with Pin 1 and Pin 3 serving as cathodes and Pin 2 as the anode. For bidirectional protection, a separate device such as MXLDA3KP6.0CE3 or back-to-back unidirectional configurations must be used - the MXLDA3KP6.0AE3 alone does not conduct symmetrically across polarity reversals.
What is the standoff voltage (VWM) of MXLDA3KP6.0AE3 and how should it be selected in circuit design?
The MXLDA3KP6.0AE3 has a rated working standoff voltage (VWM) of 6.0 V, meaning it remains non-conductive up to this DC or peak AC voltage across its terminals. In circuit design, VWM must be selected ≥10–20% above the maximum normal operating voltage of the protected line to avoid false triggering - for example, MXLDA3KP6.0AE3 is appropriate for 5 V logic rails but not for 12 V supplies. Exceeding VWM risks excessive standby leakage (1000 µA at 6.0 V), which could affect low-power system budgets.
Does MXLDA3KP6.0AE3 support high-reliability screening per MIL-PRF-19500?
Yes, MXLDA3KP6.0AE3 qualifies for optional upscreening per MIL-PRF-19500, including wafer fabrication and assembly lot traceability, 3σ screening on standby current (ID), and conformance inspections aligned with military reliability standards. While the base MXLDA3KP6.0AE3 is commercially qualified, Microsemi offers screened versions with documentation per Micronote 129. Customers requiring MIL-PRF-19500 compliance must specify screening levels at time of order - the MXLDA3KP6.0AE3 itself serves as the base die and package platform for those enhanced variants.
