Product details
Overview
MDA3KP30CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability surge protection of DC power rails and signal lines. It features a 30 V reverse standoff voltage (VWM), 33.3–36.8 V breakdown voltage (V(BR)), 48.4 V maximum clamping voltage at 62 A peak pulse current, and operates from –55 °C to +150 °C. It is RoHS-compliant (e3) and qualified per MIL-PRF-19500 screening options.
For engineers reviewing the MDA3KP30CAE3 datasheet, MDA3KP30CAE3 pinout, MDA3KP30CAE3 application, or MDA3KP30CAE3 equivalent, this device is selected for secondary lightning protection (IEC61000-4-5), ESD/EFT immunity (IEC61000-4-2/4-4), and inductive switching transient suppression in industrial power interfaces and telecom infrastructure.
Technical Context
The MDA3KP30CAE3 is a bidirectional TVS diode array with symmetrical avalanche breakdown behavior, enabling clamping of both positive and negative transients without polarity dependency. Its sub-5 ns response time and 3000 W peak pulse power rating (10/1000 µs waveform) support robust protection against fast-rising surges including lightning-induced transients and relay-switching spikes.
It employs a thermoset epoxy void-free molded case rated UL94V-0, tin-plated terminals compliant with MIL-STD-750 Method 2026, and is moisture-sensitive Level 1 (no dry pack required). Polarity is defined by dot marking; odd-numbered pins are cathodes - critical for correct PCB layout in dual-rail or differential line protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Reverse Standoff Voltage) | 30 V - Maximum continuous DC or RMS operating voltage before conduction begins. |
| V(BR) Min–Max @ I(BR) | 33.3–36.8 V @ 1 mA - Ensures reliable turn-on above system nominal voltage with margin against false triggering. |
| VC @ IPP | 48.4 V @ 62 A - Clamping voltage during 10/1000 µs surge defines worst-case overvoltage seen by protected ICs. |
| PPP (Peak Pulse Power) | 3000 W @ 10/1000 µs - Supports high-energy surge events such as IEC61000-4-5 Class 4 (42 Ω source). |
| ID @ VWM | ≤2 µA - Ultra-low leakage preserves efficiency in battery-backed or low-power monitoring circuits. |
| Operating Temperature | –55 °C to +150 °C - Enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom enclosures. |
| RoHS Compliance | e3 marking - Confirms lead-free matte-tin plating and full compliance with EU RoHS Directive 2011/65/EU. |
Pinout & Package
MDA3KP30CAE3 uses a 3-pin surface-mount DO-214AB (SMC) package with center cathode configuration: Pin 1 = Cathode, Pin 2 = Anode, Pin 3 = Cathode. The package measures 21.03 × 6.86 × 8.64 mm (L × W × H) with UL94V-0 epoxy body and matte-tin terminations. Dot marking identifies Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Bidirectional leg) | Common connection point for one side of the symmetrical TVS junction; ties to protected line or ground reference. |
| Pin 2 | Anode (Center terminal) | Shared anode node enabling bidirectional clamping between Pins 1 and 3; must be routed to system ground or common reference. |
| Pin 3 | Cathode (Bidirectional leg) | Second cathode terminal mirroring Pin 1; completes symmetrical clamping path across differential or single-ended lines. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction (C suffix) | Clamps both polarities of transient without external polarity management - simplifies protection of AC-coupled or floating lines. |
| 3000 W peak pulse power (10/1000 µs) | Withstands high-energy surges typical of industrial mains coupling and telecom line faults without degradation. |
| MIL-PRF-19500 upscreening option | Enables use in aerospace, defense, and high-integrity systems requiring lot traceability and extended reliability testing. |
| Moisture sensitivity Level 1 | Eliminates baking requirements prior to reflow, reducing manufacturing cost and process complexity. |
| Sub-5 ns response time | Engages before sensitive downstream components (e.g., RS-485 transceivers, microcontroller I/O) experience damaging overvoltage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30CA | 600 W PPP rating (vs. 3000 W); same VWM and bidirectional configuration; DO-214AA package. | Lower energy handling limits use to lower-tier ESD/EFT or board-level switching transients only. | Select when surge threat level is ≤Class 2 IEC61000-4-5 and space-constrained layouts require smaller footprint. |
| 5.0SMDJ30CA | 5000 W PPP rating; same VWM and bidirectional polarity; larger DO-214AB package with higher thermal mass. | Supports higher repetition rates and longer surge durations in utility-grade metering or grid-tie inverters. | Choose where sustained surge exposure or elevated ambient temperature (>105 °C) demands extra derating margin. |
Compared with SMBJ30CA and 5.0SMDJ30CA, the MDA3KP30CAE3 delivers balanced performance: higher energy capacity than SMBJ-class devices yet more compact and cost-effective than 5.0 kW alternatives, making it optimal for industrial control and telecom edge equipment requiring MIL-grade reliability.

FAQ
What does the 'C' in MDA3KP30CAE3 indicate?
The 'C' suffix in MDA3KP30CAE3 denotes bidirectional polarity - meaning the device provides symmetrical clamping for both positive and negative transients across its terminals. This eliminates the need for polarity-aware placement in AC-coupled or floating signal paths and is essential for protecting differential interfaces like RS-485 or Ethernet PHYs. The MDA3KP30CAE3 achieves this via a back-to-back diode configuration internal to the DO-214AB package.
Is MDA3KP30CAE3 suitable for IEC61000-4-5 Class 4 testing?
Yes, MDA3KP30CAE3 is validated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, supporting up to 4 kV test levels. Its 3000 W peak pulse power rating and 48.4 V clamping voltage at 62 A ensure protected circuitry remains within safe operating limits during standardized surge waveforms. System-level validation requires proper PCB layout, grounding, and coordination with upstream GDTs or gas arrestors.
What is the maximum allowable junction temperature for MDA3KP30CAE3?
The maximum junction temperature for MDA3KP30CAE3 is +150 °C, consistent with its specified storage and operating range of –55 °C to +150 °C. This rating enables use in high-ambient environments such as enclosed industrial drives or outdoor base stations. Derating curves (Figure 3 in RF01243 Rev B) show that at 100 °C ambient, the device retains ~75% of its 25 °C pulse power capability - critical for thermal design of high-density protection networks.
Does MDA3KP30CAE3 require dry-packing before reflow soldering?
No, MDA3KP30CAE3 is classified as Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life and does not require dry packing or baking prior to reflow. This simplifies manufacturing logistics and reduces risk of popcorn cracking during assembly. The void-free thermoset epoxy body contributes to its inherent moisture resistance and mechanical robustness.
How is polarity identified on the MDA3KP30CAE3 package?
Polarity on the MDA3KP30CAE3 is marked by a dot on the top surface of the DO-214AB package, indicating Pin 1. Per the datasheet, odd-numbered pins (Pins 1 and 3) are cathodes, while Pin 2 is the shared anode - a configuration essential for correct bidirectional clamping. Misorientation results in failed protection; visual inspection and automated optical inspection (AOI) should verify dot alignment with PCB silkscreen and footprint orientation.
