Product details
Overview
MDA3KP7.5CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in industrial and aerospace systems. It features a 7.5 V reverse standoff voltage (VWM), 8.33–9.21 V breakdown voltage (V(BR)), 12.9 V maximum clamping voltage at 100 A peak pulse current, and operates across –55 °C to +150 °C junction temperature. It protects against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5).
For engineers reviewing the MDA3KP7.5CA datasheet, MDA3KP7.5CA pinout, MDA3KP7.5CA application, or MDA3KP7.5CA equivalent, this page delivers verified electrical parameters, MIL-PRF-19500 upscreening options, bidirectional polarity confirmation, package dimensions, and IEC-compliant surge performance data - all specific to the MDA3KP7.5CA variant.
Technical Context
The MDA3KP7.5CA implements a silicon avalanche diode structure optimized for sub-nanosecond response (<5 ns) under bidirectional transients. Its clamping behavior is characterized at 10/1000 µs waveform with 3000 W peak pulse power rating and 100 A IPP, validated per Figure 2 in RF01243 Rev B.
It supports secondary lightning protection per IEC61000-4-5 at Class 1–4 with 42 Ω source impedance and Class 4 with 12 Ω source impedance. Standby leakage ID is ≤100 µA at VWM, and it meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity without dry pack requirement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.5 V - Maximum continuous operating voltage before clamping begins; sets minimum system voltage margin for reliable standby operation. |
| V(BR) min/max | 8.33–9.21 V @ 1 mA - Confirmed avalanche onset range; ensures predictable turn-on within design tolerance for overvoltage events. |
| VC @ IPP | 12.9 V @ 100 A - Clamping voltage during 10/1000 µs surge; defines worst-case voltage seen by protected circuitry. |
| PPP | 3000 W @ 10/1000 µs - Peak surge energy handling capacity; validates suitability for high-energy lightning-induced transients. |
| ID @ VWM | ≤100 µA - Low leakage current at rated standoff; minimizes power loss and avoids false triggering in low-power monitoring circuits. |
| TJ/TSTG | –55 °C to +150 °C - Extended thermal operating envelope; enables deployment in harsh environments including avionics and downhole equipment. |
Pinout & Package
MDA3KP7.5CA uses a surface-mount, void-free thermosetting epoxy package (UL94V-0 compliant) with tin-lead or matte-tin plating. Pin 1 is marked by a dot on top of the body; odd-numbered pins are cathodes per device polarity convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Channel 1) | Reference terminal for first TVS element; connects to protected line requiring bidirectional clamping. |
| Pin 2 | Anode (Channel 1) | Return path for Channel 1; tied to common ground or reference plane in differential or single-ended configurations. |
| Pin 3 | Cathode (Channel 2) | Second clamping node; enables dual-line protection (e.g., RS-485 A/B lines or dual-rail DC inputs). |
| Pin 4 | Anode (Channel 2) | Shared or independent return; supports independent or common-anode TVS configuration depending on PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetrical clamping for AC-coupled or floating signal lines without polarity constraints. |
| 3000 W peak pulse power | Supports IEC61000-4-5 Class 4 lightning testing with 12 Ω source impedance, exceeding typical industrial immunity requirements. |
| MIL-PRF-19500 screening option | Allows qualification for high-reliability applications including defense and space programs via wafer lot traceability and 3σ ID screening. |
| Level 1 moisture sensitivity | Eliminates bake-out prior to reflow; compatible with standard SMT assembly processes without dry pack 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 |
|---|---|---|---|
| SMBJ7.5CA | 600 W PPP rating, same VWM and bidirectional polarity, but lower clamping voltage (12.0 V) and smaller SMB package. | Targeted at consumer-grade or cost-sensitive designs where 3000 W surge immunity is not required. | Select when board space is constrained and surge threat level is limited to IEC61000-4-2/4-4 only. |
| SMCJ7.5CA | 1500 W PPP rating, identical VWM and VC (12.9 V), larger SMC package, no MIL-PRF-19500 screening option. | Suitable for industrial automation where moderate lightning immunity (Class 2/3) suffices and upscreening is unnecessary. | Choose when balancing cost, size, and 1500 W capability - avoids over-specifying for non-aerospace use cases. |
Compared with SMBJ7.5CA and SMCJ7.5CA, the MDA3KP7.5CA delivers triple the peak pulse power (3000 W) and formal MIL-PRF-19500 upscreening eligibility - making it uniquely suited for mission-critical systems requiring validated reliability and Class 4 lightning compliance.

FAQ
What is the polarity configuration of MDA3KP7.5CA?
The MDA3KP7.5CA is a bidirectional TVS array, indicated by the "C" suffix in its part number. This means it provides symmetrical clamping for both positive- and negative-going transients across each channel. Its internal structure consists of two back-to-back avalanche diodes per channel, enabling protection on AC-coupled or floating signal paths without polarity concerns. The MDA3KP7.5CA datasheet confirms bidirectional operation in the nomenclature section and electrical characteristics table.
Does MDA3KP7.5CA meet IEC61000-4-5 Class 4 lightning requirements?
Yes, MDA3KP7.5CA is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 12 Ω source impedance, as documented in the Applications/Benefits section of RF01243 Rev B. It achieves this with its 3000 W peak pulse power rating and 12.9 V clamping voltage at 100 A. For 42 Ω source impedance, it supports Classes 1–4; for 2 Ω, it covers Class 2 only. These classifications are confirmed in the original Microsemi specification document.
What is the maximum clamping voltage of MDA3KP7.5CA and under what test condition?
The maximum clamping voltage (VC) of MDA3KP7.5CA is 12.9 V, measured at 100 A peak pulse current (IPP) under the standardized 10/1000 µs double-exponential surge waveform. This value is specified in the Electrical Characteristics table on page 3 of RF01243 Rev B and represents the worst-case voltage imposed on protected circuitry during a full-rated surge event. It is guaranteed across the full operating temperature range.
Is MDA3KP7.5CA RoHS compliant?
Yes, MDA3KP7.5CA is RoHS compliant, as indicated by the "e3" suffix in its full marking designation per the nomenclature diagram on page 2 of RF01243 Rev B. The "e3" code denotes annealed matte-tin plating and full compliance with Directive 2011/65/EU. This applies to both standard and upscreened versions unless otherwise specified in custom ordering codes.
Can MDA3KP7.5CA be used in place of unidirectional TVS devices like MDA3KP7.5A?
No - MDA3KP7.5CA and MDA3KP7.5A are functionally distinct: the "C" suffix denotes bidirectional operation, while the blank suffix indicates unidirectional. Substituting one for the other risks improper clamping on negative transients or forward conduction in DC-biased circuits. The MDA3KP7.5CA must only replace other bidirectional variants (e.g., SMBJ7.5CA, SMCJ7.5CA) with matching VWM, VC, and PPP ratings. Always verify polarity and circuit topology before substitution.
