Product details
Overview
MDA3KP36A 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 36 V reverse standoff voltage (VWM), 40.0–44.2 V breakdown voltage (V(BR)), 58.1 V maximum clamping voltage at 51.6 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MDA3KP36A datasheet, MDA3KP36A pinout, MDA3KP36A application, or MDA3KP36A equivalent, key selection criteria include clamping performance under 10/1000 µs surge, standoff voltage margin relative to system DC bus, thermal derating above 25 °C, and compliance with IEC61000-4-5 Class 1–4 secondary lightning testing using 2–42 Ω source impedances.
Technical Context
The MDA3KP36A functions as a fast-acting, silicon-avalanche TVS diode array optimized for parallel connection across DC power rails or signal lines subject to high-energy transients. Its <100 ps response time enables suppression of ESD per IEC61000-4-2 and EFT per IEC61000-4-4, while its 3000 W peak pulse power rating supports robust protection against inductive switching spikes and secondary lightning surges.
It is rated for 10/1000 µs waveform testing with 0.05% duty factor, requires no dry pack (Moisture Sensitivity Level 1), and undergoes 3σ lot norm screening on standby current (ID). Polarity is defined by odd-numbered pins as cathodes, and it is RoHS-compliant (e3 marking).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 40.0–44.2 V @ 1 mA - Ensures reliable avalanche initiation above operating voltage with margin |
| VC @ IPP | 58.1 V @ 51.6 A - Clamping voltage during 10/1000 µs surge; defines worst-case overvoltage seen by protected circuit |
| PPP | 3000 W @ 10/1000 µs - Peak transient energy handling capacity under standardized surge waveform |
| ID @ VWM | 2 µA max - Ultra-low leakage ensures minimal power loss and no interference with high-impedance sensing |
| TJ range | –55 °C to +150 °C - Supports operation in harsh environments including automotive under-hood and industrial motor drives |
Pinout & Package
MDA3KP36A uses a 3-pin surface-mount package with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity defined by dot marking indicating Pin 1. Odd-numbered pins are cathodes; Pin 1 = Cathode, Pin 2 = Anode, Pin 3 = Cathode (dual-channel configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Channel 1) | Connected to protected line's positive rail or signal; clamps when voltage exceeds V(BR) |
| Pin 2 | Anode (Common) | Shared low-side reference; ties both channels to ground or return path |
| Pin 3 | Cathode (Channel 2) | Second protected line-enables dual-rail or differential protection without discrete devices |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables single-device protection against IEC61000-4-5 Class 4 surges (42 Ω source) on 36 V systems |
| Unidirectional construction | Prevents reverse conduction during normal operation-ideal for DC power rail protection |
| RoHS-compliant e3 marking | Meets global environmental compliance requirements without lead-free reflow complications |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring wafer/lot traceability and extended screening |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|
Use Scenario: Protection of 24–48 V DC input stages in variable-frequency drives against inductive kickback from contactors and relay coils. IC Role / Device Role / Timing Role: Transient voltage suppressor placed across DC bus inputs to clamp surge energy before reaching rectifier and capacitor stages. Use Value: Limits transient overvoltage to ≤58.1 V, preventing MOSFET gate oxide rupture and electrolytic capacitor overvoltage failure. | Use Scenario: Surge protection on -48 V telecom power distribution boards exposed to lightning-induced surges on long copper runs. IC Role / Device Role / Timing Role: Unidirectional TVS connected between -48 V rail and ground to absorb 10/1000 µs surges per IEC61000-4-5 Class 3 (12 Ω source). Use Value: Maintains system uptime by surviving repeated 3 kA surges without degradation-validated per MIL-PRF-19500 screening options. |
| Renewable Energy Inverters | Railway Signaling Interfaces |
Use Scenario: DC-link protection in solar string inverters where PV array transients couple into MPPT and DC/DC stages. IC Role / Device Role / Timing Role: Dual-cathode TVS (Pins 1 & 3) used across positive and negative DC rails relative to chassis ground. Use Value: Simultaneous clamping on both rails ensures balanced voltage stress and avoids common-mode breakdown in isolated gate drivers. | Use Scenario: Protection of 36 V signaling lines in European railway signaling cabinets subjected to EN 50121-4 conducted surge events. IC Role / Device Role / Timing Role: Mounted directly at connector entry point to shunt surge current before entering FPGA I/O banks or optocoupler inputs. Use Value: Sub-100 ps response ensures clamping initiates before ESD/EFT pulses propagate into logic-level circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | 600 W PPP rating, SMB package, 59.3 V VC @ 37.5 A | Lower energy handling; suitable only for Class 1–2 IEC61000-4-5, not Class 4 | Select when board space is constrained and surge threat level is limited to ESD/EFT or low-energy switching noise |
| SMCJ36A | 1500 W PPP rating, SMC package, 58.1 V VC @ 51.6 A (same clamping), but lower surge current endurance | Valid for Class 3 (12 Ω) but not Class 4 (42 Ω) secondary lightning per IEC61000-4-5 | Choose when cost sensitivity outweighs need for full 3000 W capability and MIL-grade reliability options |
Compared with SMBJ36A and SMCJ36A, the MDA3KP36A delivers double the peak pulse power of SMCJ36A and five times that of SMBJ36A-enabling single-device compliance with IEC61000-4-5 Class 4 at 36 V, plus optional MIL-PRF-19500 screening for aerospace and defense deployments.

FAQ
What is the clamping voltage of MDA3KP36A at its rated peak pulse current?
The MDA3KP36A has a maximum clamping voltage (VC) of 58.1 V at its rated peak pulse current (IPP) of 51.6 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 a full-rated surge event. The MDA3KP36A maintains this clamping performance across its full operating temperature range when derated per Figure 3.
Is MDA3KP36A unidirectional or bidirectional, and how is polarity marked?
MDA3KP36A is a unidirectional transient voltage suppressor, indicated by the absence of "C" in its part number suffix. Polarity is marked on the package with a dot denoting Pin 1, and odd-numbered pins (1 and 3) serve as cathodes. Pin 2 is the common anode terminal. This configuration allows dual-channel protection of separate positive rails referenced to a shared ground or return path.
Does MDA3KP36A meet IEC61000-4-5 Class 4 requirements?
Yes, MDA3KP36A meets IEC61000-4-5 Class 4 secondary lightning immunity when tested with a 42 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse power rating and 51.6 A IPP enable compliance at 36 V standoff, making it suitable for high-threat industrial and infrastructure applications where Class 4 validation is mandated.
What is the moisture sensitivity level (MSL) and soldering profile for MDA3KP36A?
MDA3KP36A is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it requires no dry pack storage or baking prior to assembly. Its maximum solder temperature is 260 °C for 10 seconds, compatible with standard leaded and lead-free reflow profiles. The thermosetting epoxy body remains stable under these conditions without delamination or popcorn effect.
Can MDA3KP36A be used for ESD protection per IEC61000-4-2?
Yes, MDA3KP36A is explicitly rated for ESD protection per IEC61000-4-2 due to its <100 ps response time and low clamping voltage. It suppresses 8 kV contact and 15 kV air discharge events by limiting transient voltage to ≤58.1 V at peak current, protecting downstream ICs such as microcontrollers, communication transceivers, and sensor front-ends. Its low standby current (2 µA max) prevents interference with sensitive analog circuits.
