Product details
Overview
MXLDA3KP36AE3 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 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 power supply inputs and telecom interfaces.
For engineers reviewing the MXLDA3KP36AE3 datasheet, MXLDA3KP36AE3 pinout, MXLDA3KP36AE3 application, or MXLDA3KP36AE3 equivalent, key selection criteria include its 36 V working voltage, sub-100 ps response time, RoHS-compliant e3 marking, 5 g weight, and MIL-PRF-19500 upscreening capability for high-reliability aerospace and defense systems.
Technical Context
The MXLDA3KP36AE3 operates as a unidirectional avalanche diode-based TVS array designed for parallel connection across sensitive DC lines. Its clamping action begins at 40.0 V (min V(BR)) and limits transients to ≤58.1 V at 51.6 A (10/1000 µs waveform), delivering 3000 W peak pulse power dissipation without degradation.
It features thermally robust epoxy packaging rated for -55 °C to +150 °C junction temperature, moisture sensitivity level 1 (no dry pack required), and tin-lead or matte-tin terminations compliant with MIL-STD-750 Method 2026. Polarity is defined by odd-numbered pins as cathodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous DC operating voltage before clamping initiates |
| V(BR) min/max | 40.0–44.2 V @ 1 mA - Ensures reliable avalanche conduction onset across process variation |
| VC @ IPP | 58.1 V @ 51.6 A (10/1000 µs) - Limits downstream voltage stress during surge events |
| PPP | 3000 W - Sustains high-energy transients common in industrial power rails and telecom ports |
| ID @ VWM | 2 µA max - Negligible leakage current preserves system efficiency in standby mode |
| Response time | <100 ps - Faster than most IC-level ESD protection, enabling upstream line protection |
| TJ/TSTG | -55 °C to +150 °C - Supports operation in extended-temperature automotive and avionics environments |
Pinout & Package
MXLDA3KP36AE3 uses a 3-pin TO-277A (SMB) surface-mount package with void-free UL94V-0 epoxy body, ~5 g mass, and polarity marked by dot indicating Pin 1. Odd-numbered pins are cathodes; Pin 1 = Cathode, Pin 2 = Anode, Pin 3 = Cathode (dual-channel configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connected to protected line; clamps positive transients to ground when referenced to Pin 2 |
| Pin 2 | Anode (common) | Shared anode node; ties both channels to system ground or return path |
| Pin 3 | Cathode of Channel 2 | Second protected line input; enables dual-rail or differential bus protection |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse rating | Supports IEC61000-4-5 Class 4 surges (42 Ω source) without failure or parameter shift |
| Unidirectional construction | Protects DC-powered circuits from positive-going transients only; avoids reverse-bias leakage in biased rails |
| MIL-PRF-19500 screening option | Enables qualification for space-grade and military platforms requiring lot traceability and 3σ ID screening |
| Moisture Level 1 | Eliminates bake-out requirement prior to reflow, reducing assembly cost and PCB warpage risk |
| e3 RoHS compliance | Meets EU Directive 2011/65/EU with lead-free matte-tin plating and halogen-free epoxy |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A | 600 W PPP rating, same VWM/V(BR)/VC, SMA package (smaller footprint, lower thermal mass) | Limited to Class 2 IEC61000-4-5; unsuitable for sustained 3000 W surges | Select when board space is constrained and surge energy is ≤600 W |
| SMCJ36A | 1500 W PPP rating, identical VWM/V(BR)/VC, SMC package (intermediate size and thermal performance) | Valid for Class 3 IEC61000-4-5 only; requires derating above 85 °C ambient | Choose for cost-sensitive industrial designs where 1500 W headroom suffices |
Compared with SMAJ36A and SMCJ36A, the MXLDA3KP36AE3 delivers double the pulse power handling of SMCJ36A and five times that of SMAJ36A-enabling single-device compliance with IEC61000-4-5 Class 4 under 42 Ω source impedance without parallel staging.

FAQ
What is the clamping voltage of MXLDA3KP36AE3 at its rated peak pulse current?
The MXLDA3KP36AE3 has a maximum clamping voltage (VC) of 58.1 V at 51.6 A peak pulse current under 10/1000 µs waveform conditions. This value is measured per standard test methods and ensures downstream circuitry remains within safe operating voltage limits during surge events. The MXLDA3KP36AE3 maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is MXLDA3KP36AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP36AE3 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 packaging meeting EU Directive 2011/65/EU requirements. This applies to all units shipped post-2019 revision and is verified through material declarations and supplier certifications for the MXLDA3KP36AE3.
Does MXLDA3KP36AE3 support MIL-PRF-19500 high-reliability screening?
Yes, MXLDA3KP36AE3 supports optional MIL-PRF-19500 upscreening including wafer lot traceability, 3σ standby current (ID) screening, and conformance inspections. While standard units are not pre-screened, Microsemi offers these options upon request with documented test reports. This capability is explicitly listed in the RF01243 datasheet for the MXLDA3KP36AE3 family.
What is the package type and pin configuration of MXLDA3KP36AE3?
MXLDA3KP36AE3 uses a 3-pin TO-277A (SMB) surface-mount package with a void-free UL94V-0 epoxy body. Pin 1 and Pin 3 are cathodes; Pin 2 is the common anode. Polarity is marked by a dot adjacent to Pin 1 on the top surface. The package dimensions are 21.03–22.05 mm in length, 6.86–7.87 mm in width, and 8.64–9.65 mm in height, as specified in the RF01243 datasheet for MXLDA3KP36AE3.
Can MXLDA3KP36AE3 be used for bidirectional transient protection?
No, MXLDA3KP36AE3 is a unidirectional TVS device, as indicated by the absence of 'C' in its part number (e.g., MDA3KP36CA would be bidirectional). It protects against positive-going transients only when the anode (Pin 2) is grounded. For bidirectional protection, a separate complementary device or a dedicated bidirectional variant like MDA3KP36CE3 must be selected instead of MXLDA3KP36AE3.
