Product details
Overview
MDA3KP15CA 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 15 V reverse standoff voltage (VWM), 16.7–18.5 V breakdown voltage (V(BR)), 24.4 V maximum clamping voltage at 123 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 supplies.
For engineers reviewing the MDA3KP15CA datasheet, MDA3KP15CA pinout, MDA3KP15CA application, or MDA3KP15CA equivalent, key selection criteria include bidirectional polarity, 15 V working voltage compatibility, 24.4 V clamping performance at 123 A, thermal derating above 25 °C, and MIL-PRF-19500 upscreening eligibility for aerospace-grade reliability requirements.
Technical Context
The MDA3KP15CA employs an avalanche diode structure optimized for sub-nanosecond response (<5 ns) under bidirectional transient stress. Its 3000 W peak pulse power rating is validated at the standard 10/1000 µs waveform with ≤0.05% duty cycle, and it maintains stable clamping performance across –55 °C to +150 °C junction temperature.
It complies with IEC61000-4-2 (±30 kV contact), IEC61000-4-4 (±4 kV), and IEC61000-4-5 (Class 1–4 secondary lightning) when used with specified source impedances (2 Ω, 12 Ω, 42 Ω). Standby leakage remains ≤2 µA at 15 V, supporting low-power system monitoring integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 16.7–18.5 V @ 1 mA - Ensures reliable avalanche initiation before system overvoltage damage occurs |
| VC @ IPP | 24.4 V @ 123 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 motor drives and telecom line cards |
| ID @ VWM | ≤2 µA - Negligible standby current avoids loading sensitive voltage rails or monitoring circuits |
| TJ/TSTG | –55 °C to +150 °C - Enables deployment in under-hood automotive, base station, and military enclosures |
Pinout & Package
MDA3KP15CA uses a 3-pin TO-220AB-style vertical surface-mount package with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity defined by a dot marking indicating Pin 1 (cathode of first TVS element). Odd-numbered pins are cathodes per internal dual-diode configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (TVS1) | Common cathode connection for first bidirectional TVS path; ties to protected line |
| Pin 2 | Anode (TVS1) / Cathode (TVS2) | Center tap forming bidirectional clamp between Pins 1 and 3; critical for symmetrical surge handling |
| Pin 3 | Anode (TVS2) | Cathode of second TVS element; completes bidirectional path with Pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetric clamping on AC lines or differential signals without polarity constraints |
| 3000 W peak pulse power | Handles high-energy surges from inductive switching or lightning-induced coupling in 48 V telecom systems |
| MIL-PRF-19500 upscreening option | Supports high-reliability qualification for aerospace and defense programs requiring lot traceability and 3σ ID screening |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | 600 W PPP rating, SMC package, 24.4 V VC @ 24.7 A IPP | Limited to lower-energy transients; unsuitable for Class 4 lightning per IEC61000-4-5 | Select when board space is constrained and surge energy is <100 mJ |
| SMCJ15CA | 1500 W PPP rating, SMC package, 24.4 V VC @ 61.5 A IPP | Half the peak power handling of MDA3KP15CA; requires parallel devices for 3000 W compliance | Choose for cost-sensitive industrial designs where full 3000 W margin is not required |
Compared with SMBJ15CA and SMCJ15CA, the MDA3KP15CA delivers double the surge energy capacity of SMCJ15CA and five times that of SMBJ15CA in the same functional voltage class, enabling single-device compliance with IEC61000-4-5 Class 4 at 42 Ω without layout redesign or paralleling.

FAQ
What does the 'C' suffix in MDA3KP15CA indicate?
The 'C' suffix in MDA3KP15CA denotes bidirectional polarity, meaning the device provides symmetrical clamping for both positive and negative transients. This distinguishes it from unidirectional variants like MDA3KP15A and enables use on AC lines or differential interfaces without external polarity considerations. The MDA3KP15CA achieves this via an internal center-tapped dual-diode configuration.
What is the maximum clamping voltage of MDA3KP15CA and at what current is it specified?
The maximum clamping voltage (VC) of MDA3KP15CA is 24.4 V, measured at its peak pulse current (IPP) of 123 A under the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Does MDA3KP15CA meet IEC61000-4-5 Class 4 lightning surge immunity?
Yes, MDA3KP15CA meets IEC61000-4-5 Class 4 secondary lightning surge immunity when tested with a 42 Ω source impedance, as confirmed in the official Microsemi datasheet (RF01243, Rev B, Page 1). Its 3000 W peak pulse power rating and 24.4 V clamping performance ensure compliance without additional external components.
Is MDA3KP15CA RoHS compliant?
Yes, MDA3KP15CA is RoHS compliant, indicated by the 'e3' suffix in its full marking per the datasheet nomenclature guide. The device uses annealed matte-tin or tin-lead plating and void-free UL94V-0 epoxy packaging, meeting EU Directive 2011/65/EU requirements without exemptions.
Can MDA3KP15CA be used in automotive under-hood applications?
Yes, MDA3KP15CA supports automotive under-hood use with its –55 °C to +150 °C junction temperature range and qualified moisture sensitivity Level 1. It withstands thermal cycling and high ambient conditions typical in engine compartments, provided PCB layout follows recommended pad dimensions and thermal relief guidelines from the datasheet.
