Product details
Overview
MDA3KP13CA 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 13 V reverse standoff voltage (VWM), 14.4–15.9 V breakdown voltage (V(BR)), 21.5 V maximum clamping voltage at 139.4 A peak pulse current, and operates from −55 °C to +150 °C. It protects against ESD, EFT, and secondary lightning per IEC61000-4-2/4-4/4-5 in telecom and industrial power interfaces.
For engineers reviewing the MDA3KP13CA datasheet, MDA3KP13CA pinout, MDA3KP13CA application, or MDA3KP13CA equivalent, key selection criteria include bidirectional polarity, 13 V working voltage compatibility, 21.5 V clamping performance under 139.4 A surge, MIL-PRF-19500 upscreening eligibility, and RoHS-compliant e3 marking - all critical for ruggedized DC power rail and Ethernet port protection designs.
Technical Context
The MDA3KP13CA employs an avalanche diode structure optimized for sub-nanosecond response (<5 ns) to transient events, enabling effective suppression of ESD (IEC61000-4-2), EFT (IEC61000-4-4), and lightning-induced surges (IEC61000-4-5). Its bidirectional configuration allows symmetrical clamping on AC-coupled or floating lines without polarity concerns.
Rated for 3000 W peak pulse power at 10/1000 µs waveform, it delivers 139.4 A IPP with 21.5 V VC while maintaining ≤5 µA standby current at 13 V. The device is qualified to MIL-PRF-19500 screening levels and features void-free UL94V-0 epoxy packaging with tin-lead or matte-tin terminations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 14.4–15.9 V @ 1 mA - Ensures reliable avalanche turn-on before system damage occurs |
| VC @ IPP | 21.5 V @ 139.4 A - Clamped voltage seen by protected circuit during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy transients common in industrial power inputs and telecom lines |
| ID @ VWM | ≤5 µA - Negligible leakage ensures no impact on low-power sensor or control circuits |
| TJ/TSTG | −55 °C to +150 °C - Supports operation in extended-temperature environments including automotive under-hood and outdoor base stations |
Pinout & Package
MDA3KP13CA uses a 2-pin DO-214AB (SMC) surface-mount package with cathode identification via dot marking. Pin 1 is cathode; Pin 2 is anode. Polarity is bidirectional - both terminals function symmetrically as cathode/anode depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (marked with dot) | Reference terminal for polarity identification; forms one side of bidirectional clamping path |
| Pin 2 | Anode | Complementary terminal; completes symmetrical avalanche path for positive/negative transients |
Key Features

|---|---|
| Bidirectional construction | Enables single-device protection of AC-coupled or floating differential lines without external polarity management |
| 3000 W peak pulse rating | Handles high-energy surges from inductive switching or lightning coupling in 48 V telecom and PoE systems |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and conformance inspection |
| RoHS-compliant e3 marking | Meets environmental compliance requirements for global industrial and telecom equipment shipments |
Applications
| Telecom Power Input Protection | Industrial PLC Analog I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | 600 W PPP rating, 13 V VWM, same DO-214AA package but lower surge capacity | Suitable for lower-energy ESD/EFT only; not rated for IEC61000-4-5 Class 3/4 lightning | Select when cost sensitivity outweighs need for 3000 W surge handling and MIL screening |
| 1.5KE13CA | 1500 W PPP, axial-leaded DO-15 package, higher thermal resistance, no MIL-PRF-19500 option | Limited to PCB space-constrained legacy designs; lacks surface-mount reliability and traceability | Choose only for through-hole prototyping or repair where SMC footprint is unavailable |
Compared with SMBJ13CA and 1.5KE13CA, the MDA3KP13CA provides triple the peak pulse power, surface-mount robustness, and military-grade screening support - making it the sole choice for mission-critical 48 V telecom feeds and outdoor industrial controllers requiring sustained surge immunity.

FAQ
What does the 'C' suffix in MDA3KP13CA indicate?
The 'C' suffix in MDA3KP13CA 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 layout and enables use on AC-coupled or floating signal/power lines. Unlike unidirectional variants (e.g., MDA3KP13A), the MDA3KP13CA has identical V(BR) and VC characteristics in either direction, confirmed in the Electrical Characteristics table on page 3 of RF01243 Rev B.
What is the maximum clamping voltage of MDA3KP13CA and under what test condition?
The maximum clamping voltage (VC) of MDA3KP13CA is 21.5 V, measured at 139.4 A peak pulse current (IPP) using a 10/1000 µs double-exponential waveform. This value is guaranteed across the full operating temperature range and represents the highest voltage imposed on the protected circuit during a standardized surge event, as specified in the Electrical Characteristics table on page 3 of the RF01243 Rev B datasheet.
Is MDA3KP13CA RoHS compliant?
Yes, MDA3KP13CA is RoHS compliant, indicated by the 'e3' marking per the part nomenclature on page 2 of RF01243 Rev B. The device uses annealed matte-tin plating on terminations and void-free UL94V-0 epoxy packaging, meeting EU Directive 2011/65/EU requirements. Non-RoHS versions are marked with blank or 'MX' suffixes, which do not apply to MDA3KP13CA.
Can MDA3KP13CA be used for IEC61000-4-5 Class 4 lightning protection?
MDA3KP13CA supports IEC61000-4-5 Class 4 secondary lightning protection only with 2 Ω source impedance, as explicitly stated on page 1 of RF01243 Rev B. It is not rated for Class 4 at 12 Ω or 42 Ω impedances. For 42 Ω systems, it qualifies up to Class 3; design validation must confirm source impedance matching to avoid underspecification in safety-critical deployments.
What is the junction temperature range for MDA3KP13CA?
The junction and storage temperature range for MDA3KP13CA is −55 °C to +150 °C, as listed in the Maximum Ratings table on page 2 of RF01243 Rev B. This extended range enables deployment in under-hood automotive modules, outdoor telecom cabinets, and industrial motor drives where ambient temperatures exceed standard commercial limits. Derating curves in Figure 3 confirm 100% power capability at 25 °C, with linear reduction above that point.
