Product details
Overview
MDA3KP36CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, designed for high-reliability secondary lightning and ESD protection. 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 MDA3KP36CAE3 datasheet, MDA3KP36CAE3 pinout, MDA3KP36CAE3 application, or MDA3KP36CAE3 equivalent, key selection criteria include IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω/2 Ω source impedances, bidirectional polarity, RoHS-compliant matte-tin plating, and 100 ps response time - all critical for industrial power interface and telecom surge protection design.
Technical Context
The MDA3KP36CAE3 implements a silicon avalanche diode structure optimized for fast transient suppression with sub-100 ps response. Its bidirectional configuration enables symmetrical clamping across both polarities without external circuitry, supporting AC-coupled signal lines and ungrounded bus protection.
Rated for 3000 W peak pulse power at 10/1000 μs waveform, it delivers stable clamping performance under repeated surges while maintaining <2 μA standby current at 36 V and full thermal derating per Figure 3 up to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous operating voltage before conduction begins; sets minimum system working voltage margin. |
| V(BR) min/max | 40.0–44.2 V - Breakdown occurs within this range at 1 mA; defines turn-on threshold tolerance band. |
| VC @ IPP | 58.1 V at 51.6 A - Clamped voltage during 10/1000 μs surge; determines protected circuit's maximum overvoltage stress. |
| PPP | 3000 W - Peak surge power handling capability; validates suitability for IEC61000-4-5 Level 4 testing. |
| TJ/TSTG | −55 °C to +150 °C - Full military-grade temperature range; supports operation in harsh industrial and aerospace environments. |
| ID @ VWM | <2 μA - Ultra-low leakage ensures minimal power loss and no interference with high-impedance sensing circuits. |
| Response time | <100 ps - Near-instantaneous avalanche response; protects against ESD per IEC61000-4-2 Contact ±8 kV. |
Pinout & Package
MDA3KP36CAE3 uses a DO-214AB (SMC) surface-mount package with two terminals: Pin 1 (cathode) and Pin 2 (anode), configured as a bidirectional TVS pair sharing a common center tap - polarity is defined by dot marking on top of package per MIL-STD-750.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Bidirectional) | Acts as cathode for positive transients and anode for negative transients; marked with dot on package top. |
| Pin 2 | Anode (Bidirectional) | Acts as anode for positive transients and cathode for negative transients; symmetric clamping path. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection of AC signals or floating buses without polarity constraints. |
| 3000 W peak pulse rating | Validates robustness against IEC61000-4-5 secondary lightning surges up to Class 4 with 42 Ω source impedance. |
| RoHS-compliant matte-tin plating | Ensures reliable solderability per MIL-STD-750 Method 2026 and eliminates lead-based process requirements. |
| MIL-PRF-19500 screening option | Supports high-reliability qualification including wafer lot traceability and 3σ ID screening for mission-critical systems. |
| Level 1 moisture sensitivity | Eliminates dry-pack requirement per IPC/JEDEC J-STD-020B - simplifies SMT handling and storage logistics. |
Applications
| Industrial Motor Drives | Telecom Power Interfaces |
|---|---|
Use Scenario: Protection of DC bus inputs in variable-frequency drives exposed to inductive switching transients and line surges. IC Role / Device Role / Timing Role: Bidirectional TVS clamps both positive and negative polarity transients on ungrounded DC link rails. Use Value: Limits voltage excursion to ≤58.1 V during 51.6 A surges, preventing gate oxide damage to IGBTs and sustaining system uptime. | Use Scenario: Surge protection on -48 V telecom power feeds entering base station equipment cabinets. IC Role / Device Role / Timing Role: Standoff at 36 V while clamping lightning-induced spikes per IEC61000-4-5 Class 4 (42 Ω source). Use Value: Maintains uninterrupted operation during multi-kA surges without latch-up or degradation after repeated events. |
| Medical Imaging Power Supplies | Railway Signaling Interfaces |
Use Scenario: Input protection for high-voltage X-ray generator power supplies subject to EFT bursts and ESD coupling. IC Role / Device Role / Timing Role: Fast-response TVS shunts EFT energy per IEC61000-4-4 (5 kHz burst) before reaching downstream regulators. Use Value: Sub-100 ps response prevents transient propagation into sensitive analog front-ends and timing circuits. | Use Scenario: Protection of 24 V signaling lines in train control systems exposed to traction-induced ground potential rise. IC Role / Device Role / Timing Role: Bidirectional clamping absorbs both positive and negative rail-to-ground transients in isolated RS-485 links. Use Value: Withstands 3000 W surges while maintaining <2 μA leakage - avoids false triggering in low-current detection logic. |
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 PPP rating vs. 3000 W; same VWM and bidirectional configuration; DO-214AA package. | Limited to Class 2/3 IEC61000-4-5; unsuitable for Class 4 or high-energy inductive switching. | Select SMBJ36CA only when surge energy is constrained to ≤600 W and board space requires smaller footprint. |
| 1.5KE36CA | 3000 W PPP but axial-leaded DO-15 package; higher thermal resistance; no RoHS e3 marking by default. | Not suitable for automated SMT assembly; requires through-hole rework and lacks moisture-level certification. | Choose 1.5KE36CA only for prototyping or legacy through-hole designs where reflow compatibility is not required. |
Compared with SMBJ36CA and 1.5KE36CA, the MDA3KP36CAE3 uniquely combines 3000 W SMT capability, RoHS e3 compliance, Level 1 moisture rating, and MIL-PRF-19500 upscreening support - making it the only option qualified for high-volume, high-reliability industrial and transportation deployments requiring zero dry-pack handling and full surge-class coverage.

FAQ
What is the clamping voltage of MDA3KP36CAE3 at its rated peak pulse current?
The MDA3KP36CAE3 has a maximum clamping voltage (VC) of 58.1 V at 51.6 A peak pulse current (IPP) under 10/1000 μs waveform conditions. This value is measured per standard test methods and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MDA3KP36CAE3 maintains this clamping performance across its full operating temperature range.
Is MDA3KP36CAE3 suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, the MDA3KP36CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, as confirmed in the manufacturer's application guidance (RF01243 Rev B, Page 1). Its 3000 W peak pulse power rating and 58.1 V clamping voltage ensure compliance with the 4 kV test level requirement for Class 4 systems.
What does the "C" and "E3" suffix mean in MDA3KP36CAE3?
In MDA3KP36CAE3, the "C" denotes bidirectional polarity, enabling symmetrical clamping for AC or floating DC lines. The "E3" indicates RoHS-compliant matte-tin terminal plating per JEDEC standards, verified by Microsemi's internal conformance testing and documented in the part nomenclature section of RF01243 Rev B.
Does MDA3KP36CAE3 require dry-pack handling per J-STD-020B?
No, the MDA3KP36CAE3 is classified as Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life and does not require dry-pack packaging or baking prior to reflow soldering. This simplifies manufacturing logistics and eliminates moisture-related yield loss during SMT assembly.
Can MDA3KP36CAE3 replace unidirectional TVS diodes in existing designs?
MDA3KP36CAE3 is bidirectional and cannot directly replace unidirectional TVS diodes without circuit review. Its symmetrical clamping behavior may alter biasing in DC-coupled paths. For unidirectional applications, use MDA3KP36AE3 instead. Always verify layout, grounding, and transient polarity assumptions before substitution - the MDA3KP36CAE3 must be applied where bidirectional protection is functionally required.
