Product details
Overview
MXDA3KP28CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, designed for high-reliability secondary lightning and ESD protection. It features a 28 V standoff voltage (VWM), 31.1–34.4 V breakdown range (V(BR)), 45.4 V max clamping voltage at 66 A peak pulse current, and operates from −55 °C to +150 °C.
For engineers reviewing the MXDA3KP28CAE3 datasheet, MXDA3KP28CAE3 pinout, MXDA3KP28CAE3 application, or MXDA3KP28CAE3 equivalent, key selection criteria include IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω/2 Ω source impedances, bidirectional polarity, RoHS-compliant matte-tin plating, and 100 ps response time - critical for telecom surge interfaces and industrial control I/O protection.
Technical Context
The MXDA3KP28CAE3 implements a symmetrical avalanche diode structure enabling bidirectional clamping without external polarity constraints. Its 3000 W peak pulse power rating (10/1000 μs waveform) and 45.4 V clamping voltage at 66 A IPP ensure robust suppression of induced RF transients and switching surges in DC power rails and signal lines.
It meets MIL-PRF-19500 screening options for high-reliability applications and exhibits <5 ns response time per IEC61000-4-2 ESD testing. Standby leakage is ≤2 μA at 28 V, and moisture sensitivity is Level 1 (no dry pack required per J-STD-020B).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 28 V - maximum continuous operating voltage before clamping begins; matches 24 V nominal DC systems with margin. |
| V(BR) min/max | 31.1–34.4 V - guaranteed avalanche onset range at 1 mA; ensures predictable turn-on across temperature and lot variation. |
| VC @ IPP | 45.4 V at 66 A - clamping voltage under 10/1000 μs surge; limits downstream IC stress during lightning-induced transients. |
| PPP | 3000 W - peak pulse power handling capacity; supports IEC61000-4-5 Class 4 with 42 Ω source impedance. |
| ID @ VWM | ≤2 μA - ultra-low standby leakage; avoids battery drain in always-on industrial sensors or remote monitoring nodes. |
| TJ/TSTG | −55 °C to +150 °C - extended junction temperature range; enables deployment in under-hood automotive ECUs or outdoor base station enclosures. |
Pinout & Package
MXDA3KP28CAE3 is housed in a DO-214AB (SMC) plastic package with void-free UL94V-0 epoxy body, matte-tin-plated terminals, and polarity defined by a dot marking indicating Pin 1 as cathode for each TVS element. The device has two terminals: anode and cathode arranged symmetrically for bidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input/Output terminal for bidirectional clamping path | Serves as common reference node for symmetrical voltage limiting; connects to protected line (e.g., RS-485 A/B or DC rail). |
| Cathode (Pin 2) | Input/Output terminal for bidirectional clamping path | Completes the low-impedance avalanche path during both positive and negative transients; ties to ground or return plane. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection of AC-coupled or differential signal lines (e.g., CAN, RS-485) without polarity concerns. |
| 3000 W peak pulse power | Supports full IEC61000-4-5 Class 4 immunity testing with 42 Ω source impedance - critical for telecom central office equipment. |
| MIL-PRF-19500 upscreening option | Allows wafer-level traceability and lot norm screening (e.g., ID), meeting aerospace and defense reliability requirements. |
| Level 1 moisture sensitivity | Eliminates bake-out prior to reflow; compatible with standard SMT assembly processes without special handling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ28CA | 600 W PPP rating, same VWM and bidirectional configuration; smaller SMB package (DO-214AA). | Limited to IEC61000-4-5 Class 2/3; unsuitable for Class 4 42 Ω testing or high-energy industrial surges. | Select when space-constrained layouts require smaller footprint and surge energy is ≤600 W. |
| SMCJ28CA | 1500 W PPP rating, identical DO-214AB package and VWM; lower clamping voltage (43.5 V) at 43.3 A IPP. | Meets Class 3 (12 Ω) but not Class 4 (42 Ω); insufficient for telecom central office or heavy-industrial surge standards. | Choose where cost optimization is prioritized and peak surge energy remains below 1500 W. |
Compared with SMBJ28CA and SMCJ28CA, MXDA3KP28CAE3 delivers double the pulse power handling of SMCJ28CA and five times that of SMBJ28CA - enabling compliance with the most stringent IEC61000-4-5 Class 4 requirements while retaining the same board footprint as SMCJ28CA.

FAQ
What is the clamping voltage of MXDA3KP28CAE3 at its rated peak pulse current?
The MXDA3KP28CAE3 has a maximum clamping voltage (VC) of 45.4 V at 66 A peak pulse current (IPP) under 10/1000 μs waveform conditions. This value is measured per Figure 2 in the official datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. Engineers use this parameter to verify that downstream components remain within their absolute maximum ratings during transient suppression.
Is MXDA3KP28CAE3 suitable for IEC61000-4-5 Class 4 compliance testing?
Yes, MXDA3KP28CAE3 supports IEC61000-4-5 Class 4 testing with a 42 Ω source impedance, as confirmed in the Applications section of the RF01243 datasheet. Its 3000 W peak pulse power rating and 45.4 V clamping voltage at 66 A enable it to absorb the full 4 kV/2 kA test waveform without failure. Designers must ensure PCB layout minimizes inductance and uses adequate ground plane area to maintain performance during validation.
Does MXDA3KP28CAE3 require special handling due to moisture sensitivity?
No, MXDA3KP28CAE3 is rated IPC/JEDEC J-STD-020B Level 1 for moisture sensitivity, meaning it does not require dry pack storage or baking prior to reflow soldering. The device's void-free thermosetting epoxy body and matte-tin plating ensure compatibility with standard SMT assembly processes, reducing manufacturing overhead and eliminating yield loss from moisture-related popcorning.
What does the "C" suffix in MXDA3KP28CAE3 indicate?
The "C" in MXDA3KP28CAE3 denotes bidirectional polarity, meaning the device provides symmetrical clamping for both positive and negative transients across its two terminals. This eliminates the need for polarity-aware placement on PCBs and makes it ideal for protecting AC-coupled or differential interfaces such as RS-485, CAN, or Ethernet PHY lines - unlike unidirectional variants (e.g., MXDA3KP28AE3) which only clamp one polarity.
How does MXDA3KP28CAE3 compare to standard SMCJ-series TVS diodes?
MXDA3KP28CAE3 delivers 3000 W peak pulse power - double the 1500 W rating of SMCJ28CA - while sharing the same DO-214AB package outline and 28 V standoff voltage. Its higher energy handling enables compliance with stricter surge immunity standards like IEC61000-4-5 Class 4, whereas SMCJ28CA is limited to Class 3. Both parts offer bidirectional operation and RoHS compliance, but MXDA3KP28CAE3 adds optional MIL-PRF-19500 upscreening capability.
