Product details
Overview
MDA3KP13A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in industrial power interfaces. 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. Used in DC power input stages of telecom base stations and industrial PLCs.
For engineers reviewing the MDA3KP13A datasheet, MDA3KP13A pinout, MDA3KP13A application, or MDA3KP13A equivalent, this page delivers verified electrical parameters, IEC61000-4-2/4-4/4-5 compliance context, package dimensions, and real-world selection guidance for surge-prone 12–15 V rail protection.
Technical Context
The MDA3KP13A is a single-channel, unidirectional TVS diode optimized for fast clamping (<100 ps response) under 10/1000 µs surge waveforms. Its 3000 W peak pulse power rating is validated per Figure 1 and sustained across −55 °C to +150 °C with derating above 25 °C per Figure 3.
It meets MIL-PRF-19500 screening options for high-reliability applications and complies with IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and IEC61000-4-5 (secondary lightning) using 42 Ω, 12 Ω, and 2 Ω source impedances - supporting Class 1–4 protection depending on impedance configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous DC operating voltage before conduction begins; matches 12 V nominal rails with margin. |
| V(BR) min/max | 14.4–15.9 V - Verified breakdown range at 1 mA; ensures reliable turn-on above system overvoltage thresholds. |
| VC @ IPP | 21.5 V - Clamping voltage at 139.4 A peak pulse; limits downstream IC stress during 3000 W transients. |
| IPP | 139.4 A - Peak impulse current at 10/1000 µs waveform; defines maximum surge energy absorption capability. |
| ID @ VWM | 5 µA - Standby leakage at rated standoff; negligible power loss in always-on protection circuits. |
| TJ/TSTG | −55 to +150 °C - Full industrial temperature range; supports operation in enclosed enclosures or outdoor cabinets. |
Pinout & Package
MDA3KP13A uses a 2-pin DO-214AB (SMC) surface-mount package with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity marked by a dot indicating Pin 1 as cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line (e.g., +12 V rail); conducts when transient exceeds V(BR). |
| Pin 2 | Anode | Connected to ground reference; completes clamping path during overvoltage events. |
Key Features

| 10/1000 µs waveform rating | Validated for standard lightning surge testing; aligns with telecom and industrial immunity standards. |
| Moisture sensitivity Level 1 | No dry pack required per J-STD-020B; simplifies SMT handling and eliminates bake-out steps. |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and conformance inspection. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | 600 W rating, SMB package, 23.2 V clamping at 26.7 A IPP | Lower energy handling; suitable only for ESD/EFT, not Class 4 lightning | Select when cost and board space constrain requirements to sub-1 kW surges. |
| SMCJ13A | 1500 W rating, same SMC package, 23.2 V clamping at 64.5 A IPP | Half the peak power of MDA3KP13A; insufficient for full IEC61000-4-5 Class 4 | Choose if legacy design uses SMCJ series and surge threat level is limited to Class 2–3. |
Compared with SMBJ13A and SMCJ13A, the MDA3KP13A delivers double the surge capacity of SMCJ13A and five times that of SMBJ13A - enabling single-device compliance with IEC61000-4-5 Class 4 at 42 Ω, while maintaining identical SMC footprint and thermal performance.

FAQ
What is the clamping voltage of MDA3KP13A at its rated peak pulse current?
The MDA3KP13A has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPP) of 139.4 A under 10/1000 µs waveform conditions. This value is measured per Figure 2 in the official datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MDA3KP13A maintains this clamping performance across its full operating temperature range when derated per Figure 3.
Is MDA3KP13A RoHS compliant?
Yes, MDA3KP13A is RoHS compliant, indicated by the "e3" suffix in its full marking per page 2 of the datasheet. The device uses annealed matte-tin plating on terminals and void-free UL94V-0 epoxy packaging, meeting lead-free soldering requirements up to 260 °C for 10 seconds. No exemptions apply, and full RoHS documentation is available through Microchip's component portal for MDA3KP13A.
Can MDA3KP13A be used for bidirectional protection?
No, MDA3KP13A is unidirectional only. Its part number lacks the "C" suffix specified for bidirectional variants (e.g., MDA3KP13CA). The device conducts only when the cathode is positive relative to the anode, making it suitable for DC rail protection but not AC line or differential signal protection. For bidirectional use, MDA3KP13CA must be selected - which has different V(BR) symmetry and clamping behavior.
What is the standoff voltage rating of MDA3KP13A and how does it relate to system design?
The MDA3KP13A has a rated reverse standoff voltage (VWM) of 13 V, meaning it remains non-conductive up to this DC or peak AC voltage. In practice, this allows direct placement on 12 V nominal systems with ~8% margin above typical ripple and tolerance. Selecting MDA3KP13A ensures no standby leakage above 5 µA while guaranteeing conduction begins no later than 14.4 V, preventing overvoltage damage to downstream components.
Does MDA3KP13A require special PCB layout considerations?
Yes - MDA3KP13A requires short, low-inductance traces between the device and protected node/ground to preserve its <100 ps response time. Per the pad layout on page 7, use the recommended SMC footprint with thermal relief minimized on both pads. Avoid vias near pins and ensure ≥2 mm clearance to adjacent copper. The 5 g mass and DO-214AB body demand adequate solder fillet height to prevent mechanical stress fracture during thermal cycling - critical for MDA3KP13A reliability in automotive or outdoor deployments.
