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 (VC) at 51.6 A peak pulse current, and operates from −55 °C to +150 °C.
For engineers reviewing the MDA3KP36A datasheet, MDA3KP36A pinout, MDA3KP36A application, or MDA3KP36A equivalent, this device is selected for robust overvoltage protection in DC power rails, telecom line cards, and automotive body control modules where fast response (<100 ps), high surge capability, and MIL-PRF-19500 upscreening options are required.
Technical Context
The MDA3KP36A is a single-channel unidirectional TVS diode optimized for 10/1000 µs surge waveforms per IEC61000-4-5. Its clamping behavior is characterized by a low 58.1 V VC at 51.6 A IPP, ensuring protected downstream circuitry remains below safe voltage thresholds during transients.
It exhibits <100 ps response time from 0 V to V(BR) min, supports 260 °C soldering per MIL-STD-750 Method 2026, and maintains ≤2 µA standby current (ID) at 36 V VWM - critical for low-power system monitoring circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous DC operating voltage before conduction begins |
| V(BR) min/max | 40.0–44.2 V @ 1 mA - defines precise turn-on threshold for reliable overvoltage triggering |
| VC @ IPP | 58.1 V @ 51.6 A - clamping voltage under full 3000 W surge, limiting stress on protected ICs |
| PPP | 3000 W @ 10/1000 µs - peak pulse power rating for lightning-induced surges |
| ID @ VWM | ≤2 µA - ultra-low leakage preserves battery life and signal integrity in always-on systems |
| TJ/TSTG | −55 °C to +150 °C - wide junction temperature range enables deployment in under-hood automotive or industrial enclosures |
Pinout & Package
MDA3KP36A uses a 2-pin SMD package with cathode-anode polarity: Pin 1 is cathode (marked by dot), Pin 2 is anode. The void-free thermosetting epoxy case meets UL94V-0 and weighs ~5 g. Dimensions: 21.03 × 6.86 × 8.64 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; conducts when transient exceeds V(BR), shunting current to ground |
| Pin 2 | Anode | Typically tied to system ground; completes current path during clamping event |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W surge rating | Enables compliance with IEC61000-4-5 Class 1–4 secondary lightning tests using 2–42 Ω source impedances |
| <100 ps response time | Clamps ESD events (IEC61000-4-2) before sensitive logic or analog circuitry is damaged |
| MIL-PRF-19500 screening option | Supports high-reliability aerospace and defense programs requiring wafer lot traceability and 3σ ID screening |
| UL94V-0 epoxy case | Provides flame-retardant mechanical encapsulation suitable for enclosed industrial power supplies |

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, same VWM and VC, but lower IPP (32.4 A) and smaller SMB package | Not suitable for Class 4 IEC61000-4-5 with 42 Ω source impedance due to lower energy handling | Select MDA3KP36A when 3000 W surge immunity is mandatory; SMBJ36A fits space-constrained designs with lower threat levels. |
| SMCJ36A | 1500 W PPP, same VWM/VC, DO-214AB package, higher thermal resistance than MDA series | Limited to Class 1–2 IEC61000-4-5; lacks MIL-PRF-19500 upscreening option | Choose MDA3KP36A for high-reliability programs requiring traceability and extended surge endurance beyond 1500 W. |
Compared with SMBJ36A and SMCJ36A, the MDA3KP36A delivers triple the peak pulse power (3000 W), validated MIL-PRF-19500 screening support, and lower thermal resistance - making it the only choice for mission-critical industrial and defense surge protection where single-event survivability is non-negotiable.

FAQ
What is the clamping voltage of the 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 ensures downstream components remain within safe operating voltage limits during high-energy transients, and is verified per Figure 2 in the official Microsemi datasheet RF01243 Rev B.
Is the MDA3KP36A RoHS compliant?
Yes, the MDA3KP36A is RoHS compliant, indicated by the "e3" suffix in its full marking per the part nomenclature on page 2 of RF01243 Rev B. The device uses annealed matte-tin plating and void-free UL94V-0 epoxy, meeting all substance restrictions defined in Directive 2011/65/EU.
Does the MDA3KP36A support MIL-PRF-19500 upscreening?
Yes, the MDA3KP36A offers optional MIL-PRF-19500 upscreening with conformance inspection options including wafer lot traceability and 3σ screening on standby current (ID). This capability is documented in the Features section of RF01243 Rev B and applies specifically to the MDA3KP36A variant.
What is the polarity configuration of the MDA3KP36A?
The MDA3KP36A is a unidirectional TVS diode: Pin 1 is cathode (marked by a dot on the package), and Pin 2 is anode. This polarity allows it to conduct only during positive transients on the cathode side, making it suitable for DC rail protection where reverse voltage blocking is required.
How does the MDA3KP36A compare to bidirectional variants like MDA3KP36CA?
The MDA3KP36A is unidirectional and blocks reverse voltage up to −36 V, whereas MDA3KP36CA is bidirectional and clamps both polarities symmetrically. The MDA3KP36A is used in DC applications with defined ground reference; MDA3KP36CA suits AC-coupled or floating signal lines where polarity reversal may occur.
