Product details
Overview
MXDA3KP30CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, featuring 30 V standoff voltage (VWM), 33.3–36.8 V breakdown voltage (V(BR)), 48.4 V clamping voltage (VC) at 62 A peak pulse current, and <5 ns response time. It delivers secondary lightning protection per IEC61000-4-5 with 12 Ω and 2 Ω source impedances and ESD/EFT suppression per IEC61000-4-2/4-4 in telecom power interfaces.
For engineers reviewing the MXDA3KP30CAE3 datasheet, MXDA3KP30CAE3 pinout, MXDA3KP30CAE3 application, or MXDA3KP30CAE3 equivalent, key selection criteria include bidirectional polarity, 30 V working voltage compatibility, 48.4 V clamping under 62 A surge, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility for high-reliability aerospace and industrial systems.
Technical Context
This TVS array uses silicon avalanche diode technology to clamp transient overvoltages before they damage downstream circuitry. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal/power lines, and its 10/1000 μs waveform-rated 3000 W peak pulse power supports robust immunity against lightning-induced surges and inductive switching transients.
The device operates across –55 °C to +150 °C junction temperature, exhibits ≤2 μA standby current at 30 V, and maintains clamping performance with <5 ns response time-critical for protecting sensitive analog front-ends, Ethernet PHYs, and RS-485 transceivers from fast-rising ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30 V maximum continuous reverse standoff voltage - matches nominal 24 V DC power rails with safety margin |
| V(BR) min/max | 33.3–36.8 V breakdown range at 1 mA - ensures reliable turn-on above operating voltage without false triggering |
| VC @ IPP | 48.4 V clamping voltage at 62 A peak pulse - limits downstream voltage stress during 10/1000 μs surges |
| PPP | 3000 W peak pulse power rating @ 10/1000 μs - sustains high-energy transients without failure |
| Response time | <5 ns - protects sub-nanosecond-sensitive circuits like Gigabit Ethernet receivers |
| ID @ VWM | ≤2 μA leakage at 30 V - avoids measurable power loss in low-quiescent-current battery systems |
| Operating temp | –55 °C to +150 °C - qualified for under-hood automotive, base station, and industrial control environments |
Pinout & Package
MXDA3KP30CAE3 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. The bidirectional configuration means both terminals function identically as clamping anodes/cathodes depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (per polarity marking) | Reference terminal for unidirectional interpretation; in bidirectional operation, serves as one clamping node |
| Pin 2 | Anode (per polarity marking) | Complementary clamping node; together with Pin 1 forms symmetrical transient path |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), and floating power domains without polarity concerns |
| 3000 W 10/1000 μs rating | Withstands repeated lightning-surge energy levels per IEC61000-4-5 Class 3 (12 Ω) and Class 2 (2 Ω) without degradation |
| MIL-PRF-19500 upscreening option | Supports high-reliability qualification for aerospace and defense programs requiring lot traceability and 3σ screening on ID |
| RoHS-compliant e3 marking | Meets lead-free assembly requirements with annealed matte-tin plating compatible with standard reflow profiles |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life constraints-ready for immediate SMT placement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package (smaller footprint) | Lower energy handling - suitable only for ESD/EFT, not secondary lightning per IEC61000-4-5 Class 2/3 | Select when board space is constrained and surge threat level is limited to IEC61000-4-2/4-4 |
| SMCJ33CA | 3000 W PPP, 33 V VWM, 36.7–40.6 V V(BR), 53.3 V VC - higher clamping voltage than MXDA3KP30CAE3 | Less voltage margin for 24 V systems - may allow higher stress on protected ICs during clamping | Select only if 33 V nominal rail requires tighter VWM match and 53.3 V clamping is acceptable |
Compared with SMBJ30CA and SMCJ33CA, MXDA3KP30CAE3 uniquely balances 30 V standoff, 48.4 V clamping, and full 3000 W lightning-surge capability in a DO-214AB package-making it optimal for 24 V industrial power inputs where both energy handling and voltage margin are critical.

FAQ
What is the clamping voltage of MXDA3KP30CAE3 at its rated peak pulse current?
The MXDA3KP30CAE3 has a maximum clamping voltage (VC) of 48.4 V at 62 A peak pulse current (IPP) under 10/1000 μs waveform conditions. This value is measured per standard test methods and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MXDA3KP30CAE3 maintains this clamping performance across its full operating temperature range from –55 °C to +150 °C.
Is MXDA3KP30CAE3 suitable for IEC61000-4-5 secondary lightning protection?
Yes, MXDA3KP30CAE3 is explicitly rated for secondary lightning protection per IEC61000-4-5 with 12 Ω and 2 Ω source impedances (Class 2 and Class 3). Its 3000 W peak pulse power rating and verified clamping behavior under 10/1000 μs waveforms meet the energy-handling requirements for these classes. The MXDA3KP30CAE3 datasheet confirms applicability for Class 2 and Class 3 testing configurations.
What does the 'C' suffix in MXDA3KP30CAE3 indicate?
The 'C' suffix in MXDA3KP30CAE3 denotes bidirectional polarity, meaning the device provides symmetrical clamping for both positive and negative transients across its two terminals. This differs from unidirectional variants (e.g., MXDA3KP30AE3), which clamp only in one direction and require correct orientation in-circuit. The MXDA3KP30CAE3 eliminates polarity installation concerns in AC-coupled or floating applications.
Does MXDA3KP30CAE3 require dry packing or special moisture handling?
No, MXDA3KP30CAE3 has IPC/JEDEC J-STD-020B moisture sensitivity Level 1, meaning it does not absorb sufficient moisture during ambient storage to require dry packing, baking, or floor-life controls. The device can be placed directly onto PCBs using standard reflow profiles without preconditioning-reducing manufacturing complexity and cost. This specification is confirmed in the official Microsemi RF01243 datasheet.
What package type is used for MXDA3KP30CAE3, and what are its key mechanical features?
MXDA3KP30CAE3 uses the DO-214AB (SMC) surface-mount package: a void-free UL94V-0 thermosetting epoxy body measuring 21.03–22.05 mm in length, with matte-tin-plated terminals compliant with MIL-STD-750 Method 2026. Polarity is marked by a dot indicating Pin 1 (cathode), and the device weighs approximately 5 grams. These mechanical attributes ensure reliability in automated SMT assembly and thermal cycling environments.
