Product details
Overview
MDA3KP15A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability overvoltage protection in power rails and signal lines. It features a 15 V 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 for industrial and aerospace applications.
For engineers reviewing the MDA3KP15A datasheet, MDA3KP15A pinout, MDA3KP15A application, or MDA3KP15A equivalent, key selection criteria include clamping performance under IEC61000-4-5 secondary lightning (42 Ω source), ESD/EFT immunity per IEC61000-4-2/4-4, and thermal derating above 25 °C per Figure 3.
Technical Context
The MDA3KP15A employs silicon avalanche diode technology with sub-100 ps response time, enabling suppression of fast transients including ESD and inductive switching spikes. Its unidirectional polarity and cathode-defined odd-pin configuration support DC-biased rail protection without reverse conduction.
Rated for 3000 W peak pulse power at 10/1000 μs waveform, it delivers 24.4 V clamping at 123 A IPP while maintaining ≤2 μA standby leakage at 15 V VWM - critical for low-power system integrity and battery-backed circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - maximum continuous working voltage before clamping initiates; matches 12 V nominal rail with margin |
| V(BR) min/max | 16.7–18.5 V - guaranteed avalanche onset range at 1 mA; ensures consistent turn-on across temperature |
| VC @ IPP | 24.4 V at 123 A - limits downstream voltage stress during 10/1000 μs surge events |
| IPP | 123 A - peak surge current capability per IEC61000-4-5 Class 1–4 testing with 42 Ω source |
| ID @ VWM | ≤2 μA - ultra-low leakage preserves battery life and avoids false triggering in high-impedance nodes |
| TJ/TSTG | –55 °C to +150 °C - supports operation in extended-temperature environments including avionics and motor drives |
Pinout & Package
MDA3KP15A uses a 3-pin SMC (DO-214AB) surface-mount package with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity defined by dot marking on top: Pin 1 = cathode, Pin 2 = anode, Pin 3 = cathode (dual-channel configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Channel 1) | Connects to protected line; clamps positive transients to ground when voltage exceeds V(BR) |
| Pin 2 | Anode (Common) | Shared anode node tied to system ground or negative rail; enables dual-channel unidirectional layout |
| Pin 3 | Cathode (Channel 2) | Second protected line input; identical clamping behavior to Pin 1 for multi-rail protection |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse rating | Enables single-device protection against severe IEC61000-4-5 surges up to Class 4 (42 Ω source) |
| Sub-100 ps response time | Clamps ESD events (IEC61000-4-2) before sensitive ICs experience overstress |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing cost |
| MIL-PRF-19500 screening option | Supports high-reliability qualification for aerospace and defense programs with full lot traceability |
| UL94V-0 epoxy package | Meets flammability requirements for safety-critical enclosures and industrial control panels |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | 600 W rating, 24.4 V clamping at 24.7 A IPP - lower energy handling | Suitable for consumer-grade ESD/EFT only; not rated for IEC61000-4-5 Class 4 | Select when cost and board space constrain design, and surge threat level is limited to IEC61000-4-2/4-4 |
| SMCJ15A | 1500 W rating, 24.4 V clamping at 61.5 A IPP - half the energy capacity of MDA3KP15A | Valid for IEC61000-4-5 Class 1–2 (42 Ω), but fails Class 3–4 validation | Choose for mid-tier industrial systems requiring MIL-STD-810G compliance but not DO-160 or MIL-PRF-19500 screening |
Compared with SMBJ15A and SMCJ15A, the MDA3KP15A delivers double the peak pulse power and validated Class 4 lightning immunity - making it the only option among the three qualified for high-reliability aerospace and heavy-industrial deployments requiring full 3000 W surge margin.

FAQ
What is the clamping voltage of MDA3KP15A at its rated peak pulse current?
The MDA3KP15A has a maximum clamping voltage (VC) of 24.4 V at 123 A peak pulse current (IPP) 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 MDA3KP15A maintains this clamping performance across its full operating temperature range.
Is MDA3KP15A RoHS compliant?
Yes, MDA3KP15A is RoHS compliant, indicated by the "e3" suffix in its full part marking per Microsemi's nomenclature guide. The device uses annealed matte-tin plating and void-free UL94V-0 epoxy packaging, meeting EU Directive 2011/65/EU requirements. No lead or hazardous substances exceeding threshold limits are present in the MDA3KP15A construction.
Does MDA3KP15A support bidirectional transient suppression?
No, MDA3KP15A is a unidirectional TVS array. Its part number lacks the "C" suffix required for bidirectional variants (e.g., MDA3KP15CA). The device clamps only positive-going transients relative to its common anode (Pin 2); reverse voltage beyond ~1.2 V forward drop will conduct but is not specified for protection. For AC or bipolar rail protection, MDA3KP15CA must be selected instead.
What is the standoff voltage rating of MDA3KP15A and how does it relate to system design?
The MDA3KP15A has a rated reverse standoff voltage (VWM) of 15 V - the maximum continuous DC or peak AC voltage that can be applied without triggering clamping. System designers must ensure normal operating voltage (e.g., 12 V nominal rail) remains below this value with margin for ripple and tolerance. Exceeding VWM risks excessive standby current and thermal instability, so MDA3KP15A is matched to 12–15 V applications.
Can MDA3KP15A be used for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MDA3KP15A is explicitly validated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse rating and 123 A IPP meet the 4 kV test level requirement. Derating per Figure 3 must be applied above 25 °C ambient to maintain compliance.
