Product details
Overview
MXDA3KP30CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in power and signal lines. It features a 30 V standoff voltage (VWM), 33.3–36.8 V breakdown voltage (V(BR)), 48.4 V clamping voltage at 62 A peak pulse current, and operates across –55 °C to +150 °C. It protects against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5) in telecom and industrial power interfaces.
For engineers reviewing the MXDA3KP30CA datasheet, MXDA3KP30CA pinout, MXDA3KP30CA application, or MXDA3KP30CA equivalent, this page delivers verified electrical parameters, bidirectional polarity mapping, IEC-compliant surge class coverage (Class 1–4 at 42 Ω/12 Ω source impedances), and traceable RoHS-compliant packaging per MIL-PRF-19500 screening options.
Technical Context
The MXDA3KP30CA implements a monolithic silicon avalanche diode structure optimized for sub-5 ns response time and low clamping ratio (VC/V(BR) ≈ 1.45). Its bidirectional configuration enables symmetrical clamping on AC-coupled or floating lines without external polarity management.
It is rated for 3000 W peak pulse power at 10/1000 µs waveform, with full surge testing per device lot and 3σ screening on standby current (ID ≤ 2 µA @ 30 V). Moisture sensitivity is Level 1 (J-STD-020B), eliminating dry-pack requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30 V - Maximum continuous operating voltage before clamping begins; matches 24 V DC systems with safety margin. |
| V(BR) min–max | 33.3–36.8 V - Confirmed avalanche onset range at 1 mA; ensures predictable turn-on across temperature and lot variance. |
| VC @ IPP | 48.4 V - Clamping voltage at 62 A peak pulse; limits downstream voltage stress during 10/1000 µs transients. |
| IPP | 62 A - Peak impulse current capability; supports IEC61000-4-5 Class 4 surges with 42 Ω source impedance. |
| ID @ VWM | ≤2 µA - Ultra-low leakage at rated standoff; avoids power loss or false triggering in high-impedance monitoring circuits. |
| TJ/TSTG | –55 °C to +150 °C - Extended thermal range enables deployment in under-hood automotive or industrial motor drive environments. |
| Package | DO-214AB (SMC) - Surface-mount, void-free epoxy case rated UL94V-0; compatible with standard reflow profiles up to 260 °C. |
Pinout & Package
MXDA3KP30CA uses a 2-pin DO-214AB (SMC) package with bidirectional symmetry: Pin 1 and Pin 2 are interchangeable terminals of a single monolithic TVS junction. Polarity marking is not applicable; the device conducts equally in both directions above V(BR). The package body includes a dot indicating Pin 1 per JEDEC standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | Interchangeable terminal; no fixed polarity - connects to either side of protected line pair (e.g., RS-485 A/B or AC input). |
| Pin 2 | Anode/Cathode (bidirectional) | Interchangeable terminal; forms symmetrical clamp path with Pin 1 - eliminates need for orientation-aware layout. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines (e.g., CAN, RS-485) without polarity constraints. |
| 3000 W peak pulse rating | Withstands 10/1000 µs surges up to 62 A - meets IEC61000-4-5 Class 4 at 42 Ω source impedance. |
| MIL-PRF-19500 screening option | Supports high-reliability qualification including wafer/lot traceability, 3σ ID screening, and surge testing per lot. |
| RoHS-compliant (e3) | Matte-tin plating per MIL-STD-750 Method 2026 ensures solderability and eliminates lead-based finishes. |
| Level 1 moisture sensitivity | No dry-pack required - simplifies handling and storage for production lines per J-STD-020B. |

IC Role / Device Role / Timing Role: Bidirectional clamp across differential pair (A/B), absorbing ±15 kV ESD (IEC61000-4-2) and 40 A EFT bursts. Use Value: Sub-5 ns response ensures clamping occurs before transceiver input stages experience overstress - preserves data integrity during EMC events. | Use Scenario: Secondary surge suppression on AC-DC adapter primary-side rectified outputs in medical equipment meeting IEC60601-1. IC Role / Device Role / Timing Role: Parallel-connected TVS limiting transient overshoot after MOV clamping, reducing let-through energy to downstream capacitors and ICs. Use Value: 3000 W rating handles residual surges post-MOV, while 30 V VWM avoids conduction during normal 35 V peak rectified waveforms. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33CA | 600 W rating, 33 V VWM, DO-214AA package - lower power handling and smaller footprint. | Suitable for lower-energy ESD/EFT only; not rated for IEC61000-4-5 Class 4 lightning surges. | Select when board space is constrained and peak surge energy remains below 150 mJ. |
| SMCJ33CA | 1500 W rating, 33 V VWM, DO-214AB package - same footprint but half the peak power of MXDA3KP30CA. | Meets IEC61000-4-5 Class 2–3 only; insufficient for 4 kV/42 Ω Class 4 compliance. | Choose for cost-sensitive designs where full 3000 W capability is not required and thermal derating is acceptable. |

FAQ
What is the clamping voltage of MXDA3KP30CA at its rated peak pulse current?
The MXDA3KP30CA has a maximum clamping voltage (VC) of 48.4 V at 62 A peak pulse current (IPP), measured under 10/1000 µs waveform conditions. This value ensures downstream circuitry remains within safe operating limits during standardized surge events. The MXDA3KP30CA maintains this clamping performance across its full operating temperature range of –55 °C to +150 °C.
Is MXDA3KP30CA unidirectional or bidirectional, and how does that affect PCB layout?
MXDA3KP30CA is a bidirectional TVS, indicated by the "C" suffix in its part number. This means it provides symmetrical clamping for both positive and negative transients without polarity sensitivity. As a result, PCB layout requires no orientation alignment - either pin may connect to either side of the protected line pair, simplifying routing for differential interfaces like RS-485 or AC signals. The MXDA3KP30CA's dot-marked Pin 1 serves only as a mechanical reference, not a polarity indicator.
Does MXDA3KP30CA meet IEC61000-4-5 Class 4 lightning surge requirements?
Yes, MXDA3KP30CA meets IEC61000-4-5 Class 4 (4 kV) for secondary lightning surge immunity when tested with a 42 Ω source impedance. Its 3000 W peak pulse power rating and 62 A IPP capability are validated for this condition. The device also supports Class 1–3 at 12 Ω and Class 2–3 at 2 Ω source impedances. MXDA3KP30CA's performance is documented in Microsemi's RF01243 datasheet, Figure 2 and Table on Page 3.
What is the standoff voltage (VWM) of MXDA3KP30CA, and why is it important for system design?
The MXDA3KP30CA has a rated working standoff voltage (VWM) of 30 V - the maximum continuous DC or RMS voltage it can withstand without significant leakage or clamping. This value must exceed the peak operating voltage of the protected circuit (e.g., 24 V DC systems) to prevent false triggering. At 30 V, MXDA3KP30CA allows safe margin for ripple and tolerance while maintaining ≤2 µA standby current, minimizing power loss in always-on systems.
Is MXDA3KP30CA RoHS-compliant and qualified for high-reliability applications?
Yes, MXDA3KP30CA is RoHS-compliant (e3 marking), with annealed matte-tin plating per MIL-STD-750 Method 2026. It supports optional high-reliability screening per MIL-PRF-19500, including wafer/lot traceability, 3σ standby current screening, and lot-level surge testing. Its DO-214AB package meets UL94V-0 flammability and J-STD-020B Level 1 moisture sensitivity - no dry-pack required. MXDA3KP30CA is specified for operation from –55 °C to +150 °C.
