Product details
Overview
MXLDA3KP22AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 22 V standoff voltage (VWM), 24.4–26.9 V breakdown range (V(BR)), and 35.5 V maximum clamping voltage (VC) at 84.4 A peak pulse current (IPP). 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 MXLDA3KP22AE3 datasheet, MXLDA3KP22AE3 pinout, MXLDA3KP22AE3 application, or MXLDA3KP22AE3 equivalent, key selection criteria include its 22 V working standoff, sub-100 ps response time, RoHS-compliant e3 marking, 150 °C max junction temperature, and compatibility with high-reliability MIL-PRF-19500 upscreening options.
Technical Context
The MXLDA3KP22AE3 operates as a unidirectional avalanche diode-based TVS, designed for fast clamping of transient overvoltages on DC power rails and signal lines. Its 10/1000 µs surge rating of 3000 W and <100 ps response ensure protection against lightning-induced surges, ESD events, and inductive kickback without affecting normal circuit operation.
It features a thermosetting epoxy package rated UL94V-0, tin-lead or matte-tin terminations, and polarity defined by odd-numbered pins as cathodes. Standby leakage is limited to 2 µA at 22 V, enabling low-power system integration without significant quiescent loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22 V - Maximum continuous DC or peak AC voltage the device blocks without clamping |
| V(BR) min/max | 24.4–26.9 V @ 1 mA - Ensures reliable avalanche conduction onset above operating voltage |
| VC @ IPP | 35.5 V @ 84.4 A - Limits downstream voltage stress during worst-case 10/1000 µs transients |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy surges common in industrial power line coupling |
| ID @ VWM | 2 µA - Negligible leakage for battery-backed or low-quiescent systems |
| TJ/TSTG | −55 to +150 °C - Supports deployment in extended-temperature industrial and aerospace environments |
| Response time | <100 ps - Clamps before sensitive ICs experience latch-up or gate oxide damage |
Pinout & Package
MXLDA3KP22AE3 uses a 3-pin TO-277A (SMB) surface-mount package with void-free UL94V-0 epoxy body, matte-tin or tin-lead terminations, and polarity indicated by a dot marking pin 1. Odd-numbered pins are cathodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Anode-side connection point; connects to protected line requiring clamping to ground or rail |
| Pin 2 | Anode | Reference node (typically GND or negative rail); completes clamping path during overvoltage |
| Pin 3 | Cathode | Second independent cathode terminal; enables dual-channel or redundant protection layout |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Handles high-energy transients from lightning coupling or motor commutation without failure |
| RoHS-compliant e3 marking | Meets global environmental compliance requirements for industrial and telecom equipment |
| MIL-PRF-19500 upscreening option | Enables qualification for high-reliability aerospace, defense, and critical infrastructure applications |
| UL94V-0 epoxy package | Provides flame-retardant mechanical integrity under thermal stress and surge conditions |
| Level 1 moisture sensitivity | Eliminates dry-pack requirement and floor-life constraints for standard SMT assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Lower PPP (400 W), same VWM (22 V), SMA package (smaller footprint, lower thermal mass) | Not suitable for IEC61000-4-5 Class 4; limited to low-energy ESD/EFT only | Select when board space is constrained and surge energy remains below 400 W. |
| SMCJ22A | Same PPP (3000 W), identical VWM (22 V), but SMC package (larger, higher thermal dissipation) | Compatible with same IEC61000-4-5 classes but requires larger PCB area and different pad layout | Choose when enhanced thermal cycling reliability or legacy SMC footprint compatibility is required. |
Compared with SMAJ22A and SMCJ22A, the MXLDA3KP22AE3 delivers identical 3000 W surge capability in a compact TO-277A outline with MIL-PRF-19500 upscreening support-making it optimal for space-constrained, high-reliability industrial systems where traceability and extended temperature operation are mandatory.

FAQ
What is the clamping voltage of MXLDA3KP22AE3 at its rated peak pulse current?
The MXLDA3KP22AE3 has a maximum clamping voltage (VC) of 35.5 V at its rated peak pulse current (IPP) of 84.4 A under 10/1000 µs waveform conditions. This value is guaranteed per the manufacturer's electrical characteristics table and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MXLDA3KP22AE3 maintains this clamping performance across its full operating temperature range of −55 to +150 °C.
Is MXLDA3KP22AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP22AE3 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 full compliance with Directive 2011/65/EU, including restrictions on lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE. The MXLDA3KP22AE3 meets these requirements without exemptions and is suitable for environmentally regulated end equipment.
Does MXLDA3KP22AE3 support MIL-PRF-19500 screening and what does that entail?
Yes, MXLDA3KP22AE3 supports optional MIL-PRF-19500 upscreening, including wafer lot traceability, 3σ lot norm screening on standby current (ID), and conformance inspections aligned with JANTXV-level reliability requirements. This screening is documented in Micronote 129 and enables use in defense, aerospace, and critical infrastructure applications. The MXLDA3KP22AE3 retains its full 3000 W surge rating and 22 V VWM specification under screened conditions.
What is the package type and pin configuration of MXLDA3KP22AE3?
MXLDA3KP22AE3 uses a 3-pin TO-277A (SMB) surface-mount package with a UL94V-0 epoxy body and matte-tin or tin-lead terminations. Pin 1 is marked by a dot and serves as cathode; Pin 2 is the anode; Pin 3 is a second cathode. This configuration allows flexible implementation in single-line or dual-cathode protection topologies. The MXLDA3KP22AE3 package dimensions are fully specified in the official Microsemi datasheet RF01243 Rev B.
How does MXLDA3KP22AE3 compare to bidirectional TVS devices like MDA3KP22CE3?
MXLDA3KP22AE3 is unidirectional and optimized for clamping positive transients to ground, whereas MDA3KP22CE3 is bidirectional and protects against both polarities. The MXLDA3KP22AE3 offers lower clamping voltage (35.5 V vs. 38.9 V for the bidirectional variant at same IPP) and is preferred for DC rail protection where polarity is fixed. Unlike MDA3KP22CE3, the MXLDA3KP22AE3 cannot suppress negative-going surges without external circuitry.
