Product details
Overview
MXLDA3KP36A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 36 V standoff voltage (VWM), 40.0–44.2 V breakdown voltage (V(BR)), and 58.1 V maximum clamping voltage (VC) at 51.6 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 industrial power interfaces.
For engineers reviewing the MXLDA3KP36A datasheet, MXLDA3KP36A pinout, MXLDA3KP36A application, or MXLDA3KP36A equivalent, key selection criteria include its 36 V working voltage, 51.6 A surge rating at 10/1000 µs, <100 ps response time, RoHS-compliant void-free epoxy package, and MIL-PRF-19500 upscreening capability for high-reliability deployments.
Technical Context
The MXLDA3KP36A operates as a unidirectional avalanche diode-based TVS, designed to clamp transients before downstream circuitry exceeds safe voltage thresholds. Its breakdown occurs at 40.0–44.2 V under 1 mA test current, with clamping initiated within <100 ps and sustained at ≤58.1 V during 51.6 A 10/1000 µs pulses.
It is rated for continuous operation from –55 °C to +150 °C junction temperature, features tin-lead or matte-tin terminations compliant with MIL-STD-750 Method 2026, and undergoes 3σ lot norm screening on standby current (ID ≤ 2 µA at 36 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min–max | 40.0–44.2 V @ 1 mA - Confirmed avalanche onset range ensuring predictable turn-on margin above VWM |

| Response time | <100 ps - Enables effective suppression of ESD events (IEC61000-4-2) and fast EFT bursts |
Pinout & Package
MXLDA3KP36A uses a 3-pin surface-mount package with cathode-defined polarity: Pin 1 = Cathode, Pin 2 = Anode, Pin 3 = Cathode (dual-channel configuration). The void-free thermosetting epoxy case meets UL94V-0; marking includes date code and part number, with polarity indicated by a dot adjacent to Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Channel 1) | Connected to protected line; conducts when line voltage exceeds V(BR) relative to common |
| Pin 2 | Anode (Common) | Reference node tied to system ground or return path; shared between both TVS channels |
| Pin 3 | Cathode (Channel 2) | Second protected line input; enables dual-line differential or independent rail protection |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional construction | Enables DC-biased line protection with precise polarity alignment and no reverse leakage during normal operation |
| 3000 W peak pulse power | Supports robust immunity against IEC61000-4-5 Class 4 surges (42 Ω source) without degradation |
| MIL-PRF-19500 upscreening option | Allows qualification for aerospace, defense, and critical infrastructure applications requiring wafer/lot traceability |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing assembly cost and risk |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | 600 W PPP rating, SMC package, 59.3 V VC @ 32.3 A | Limited to lower-energy transients; not rated for IEC61000-4-5 Class 4 | Select when board space is constrained and surge threat level is ≤Class 2 |
| SMCJ36A | 1500 W PPP rating, same SMC package, 58.1 V VC @ 43.4 A | Half the peak power handling; insufficient for 42 Ω Class 4 lightning testing | Choose where cost sensitivity outweighs need for full 3000 W margin |
Compared with SMBJ36A and SMCJ36A, MXLDA3KP36A delivers double the surge energy capacity and verified Class 4 lightning compliance-critical for infrastructure-grade designs where single-point failure must be avoided.

FAQ
What is the clamping voltage of MXLDA3KP36A at its rated peak pulse current?
The MXLDA3KP36A has a maximum clamping voltage (VC) of 58.1 V at its rated peak pulse current (IPP) of 51.6 A under 10/1000 µs waveform conditions. This value is measured across the device terminals during standardized surge testing and defines the upper voltage limit imposed on protected circuitry during worst-case transients. The MXLDA3KP36A maintains this clamping performance across its full operating temperature range.
Is MXLDA3KP36A RoHS-compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP36A is RoHS-compliant, as confirmed by the 'e3' marking per Microsemi's part nomenclature. The 'e3' designation specifies annealed matte-tin plating on terminations and full compliance with Directive 2011/65/EU, including lead content below 1000 ppm. This ensures compatibility with modern lead-free reflow processes without compromising surge performance or reliability. MXLDA3KP36A meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity requirements.
Does MXLDA3KP36A support MIL-PRF-19500 screening and what does that entail?
Yes, MXLDA3KP36A supports optional MIL-PRF-19500 upscreening, including wafer-level traceability, lot conformance inspection, and 3σ statistical screening on standby current (ID). This qualification path enables use in defense, aerospace, and safety-critical industrial systems where process control and failure rate predictability are mandated. Screening details are documented in Micronote 129, and MXLDA3KP36A retains full 3000 W surge capability post-screening.
How many protected channels does MXLDA3KP36A provide and how is polarity configured?
MXLDA3KP36A provides two independent unidirectional TVS channels sharing a common anode (Pin 2), with cathodes on Pin 1 and Pin 3. This configuration allows simultaneous protection of two separate lines referenced to the same ground plane-ideal for differential buses or dual-rail inputs. Polarity is fixed: odd-numbered pins are cathodes, and the device must be oriented so cathodes connect to protected lines and the anode ties to system ground or return.
What is the maximum standoff voltage and why is it important for MXLDA3KP36A selection?
The maximum standoff voltage (VWM) of MXLDA3KP36A is 36 V, representing the highest continuous DC or peak AC voltage the device blocks without entering breakdown. Selecting a VWM equal to or greater than the circuit's normal operating voltage prevents false triggering while maintaining sufficient margin to V(BR) (40.0–44.2 V). For a 36 V nominal system, MXLDA3KP36A offers optimal balance between immunity margin and clamping headroom.
