Product details
Overview
MDA3KP36CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability secondary lightning and ESD protection. It features a 36 V standoff voltage (VWM), 40.0–44.2 V breakdown range (V(BR)), 58.1 V clamping voltage at 51.6 A peak pulse current, and operates from −55 °C to +150 °C - used in telecom power interfaces and industrial I/O protection.
For engineers reviewing the MDA3KP36CA datasheet, MDA3KP36CA pinout, MDA3KP36CA application, or MDA3KP36CA equivalent, key selection criteria include bidirectional polarity, 3000 W 10/1000 µs surge rating, IEC61000-4-2/4-4/4-5 compliance, RoHS-compliant e3 marking, and MIL-PRF-19500 upscreening availability.
Technical Context
The MDA3KP36CA is a silicon avalanche diode-based TVS array with bidirectional conduction, enabling symmetrical clamping of positive and negative transients. Its sub-5 ns response time ensures effective suppression of ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5) with 2 Ω, 12 Ω, and 42 Ω source impedances.
It delivers 3000 W peak pulse power at 10/1000 µs waveform, with clamping voltage specified at 58.1 V maximum under 51.6 A IPP, and exhibits <2 µA standby current at 36 V VWM - confirming low leakage for stable DC bias integrity in protected signal/power lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before clamping begins; matches 33–36 V DC bus or interface supply rails. |
| V(BR) min/max | 40.0–44.2 V - guaranteed avalanche onset range at 1 mA; ensures predictable turn-on margin above VWM. |
| VC @ IPP | 58.1 V max at 51.6 A - peak clamped voltage during 10/1000 µs surge; defines worst-case overvoltage seen by downstream ICs. |
| IPP | 51.6 A - maximum non-destructive surge current at rated waveform; determines minimum series impedance needed for coordination. |
| ID @ VWM | <2 µA - ultra-low leakage at rated standoff; avoids loading sensitive analog or reference circuits. |
| TJ/TSTG | −55 °C to +150 °C - extended thermal range supports operation in harsh industrial, aerospace, and outdoor enclosures. |
| PPP | 3000 W @ 10/1000 µs - standardized surge energy handling capacity; validated per Figure 1 and Table on p.3. |
Pinout & Package
MDA3KP36CA uses a 3-pin surface-mount package with void-free UL94V-0 epoxy body and tin-lead or matte-tin plating. Pin 1 is marked by a dot; odd-numbered pins are cathodes per internal diode configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connects to protected line side; forms bidirectional clamp path with Pin 2 as common anode node. |
| Pin 2 | Common Anode | Shared anode terminal for both internal diodes; ties to system ground or low-impedance return plane. |
| Pin 3 | Cathode of Channel 2 | Connects to second protected line (e.g., differential pair leg); enables dual-line or data-line protection. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetrical clamping of ± transients without polarity sensitivity - ideal for AC-coupled or differential interfaces. |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and conformance inspection per military standard. |
| Moisture sensitivity Level 1 | No dry pack or bake-out required before reflow - simplifies SMT assembly and reduces manufacturing risk. |
| RoHS-compliant e3 marking | Meets EU Directive 2011/65/EU with lead-free matte-tin plating - verified via part number suffix 'e3' per nomenclature guide. |
Applications
| Industrial PLC I/O Protection | Telecom Power Interface |
|---|---|
Use Scenario: Protecting 24 V DC digital input modules from inductive switching spikes and field-wiring surges.

Use Value: <2 µA leakage preserves high-impedance measurement accuracy; 150 °C rating supports sterilization-cycle thermal stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | 600 W rating (vs. 3000 W); same VWM/V(BR)/VC but lower IPP (32.4 A vs. 51.6 A) | Not suitable for Class 4 IEC61000-4-5 with 42 Ω source; limited to lower-energy ESD/EFT only | Select when board space is constrained and surge threat level is ≤ Class 2. |
| SMCJ36CA | 1500 W rating; identical VWM/V(BR)/VC specs but IPP = 25.8 A; larger SMC package (7.11 × 6.22 mm vs. MDA's 22.05 × 9.65 mm) | Lower energy handling restricts use to non-lightning environments; requires different PCB footprint | Choose if legacy SMC layout exists and 3000 W capability is not required. |
Compared with SMBJ36CA and SMCJ36CA, the MDA3KP36CA provides 2× and 4× higher peak pulse power respectively, enabling robust secondary lightning protection in infrastructure-grade equipment where sustained surge energy must be absorbed without degradation.

FAQ
What does the 'C' in MDA3KP36CA indicate?
The 'C' suffix in MDA3KP36CA denotes bidirectional polarity - meaning the device contains two back-to-back avalanche diodes sharing a common anode (Pin 2), enabling symmetrical clamping of both positive and negative transients. This differs from unidirectional variants like MDA3KP36A, which protect only one polarity relative to ground. The MDA3KP36CA is therefore suited for AC-coupled lines, differential buses, or any application where voltage reversals may occur.
Is MDA3KP36CA RoHS compliant?
Yes, MDA3KP36CA is RoHS compliant, indicated by the 'e3' marking on the package per Microsemi's nomenclature guide. The device uses annealed matte-tin plating on terminals and meets EU Directive 2011/65/EU requirements. No lead or restricted substances exceed allowable thresholds, and the UL94V-0 epoxy body is halogen-free - confirmed in RF01243 Rev B documentation and Microchip's official product change notices.
What is the maximum clamping voltage of MDA3KP36CA under surge conditions?
The maximum clamping voltage (VC) of MDA3KP36CA is 58.1 V, measured at its rated peak pulse current (IPP) of 51.6 A under the standard 10/1000 µs waveform. This value represents the worst-case voltage imposed on protected circuitry during a full-rated surge event. It is guaranteed across temperature and process variation, and appears in the Electrical Characteristics table on page 3 of RF01243 Rev B.
Can MDA3KP36CA be used for IEC61000-4-5 Class 4 lightning protection?
Yes, MDA3KP36CA is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, as stated in the Applications/Benefits section (page 1). Its 3000 W peak pulse power and 51.6 A IPP meet the 4 kV open-circuit/2 kA short-circuit test requirements for Class 4. Coordination with upstream filters or gas discharge tubes may still be required depending on system-level architecture.
Does MDA3KP36CA require moisture baking before reflow soldering?
No, MDA3KP36CA does not require moisture baking prior to reflow. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - the lowest classification - meaning it can be stored indefinitely at ambient conditions and placed directly into standard reflow profiles without dry-packaging or bake-out. This is confirmed in the Features section (page 1) and eliminates a critical process step in high-volume SMT manufacturing.
