Product details
Overview
MXLPLAD36KP30CAE3 from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace and automotive systems. It delivers 36,000 W peak pulse power at 10/1000 μs, features a 30 V reverse standoff voltage (VWM), clamps to ≤48.8 V at 738 A peak pulse current, and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MXLPLAD36KP30CAE3 datasheet, MXLPLAD36KP30CAE3 pinout, MXLPLAD36KP30CAE3 application, or MXLPLAD36KP30CAE3 equivalent, key selection criteria include its bidirectional polarity, 30 V VWM rating, low thermal resistance (RθJC = 1.0 °C/W), RoHS-compliant e3 termination, and qualification per AEC-Q101 and MIL-PRF-19500 screening levels.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuitry, activating above its 30 V standoff voltage to divert transients up to 738 A while limiting voltage to 48.8 V. Its void-free thermosetting epoxy package and metal-base cathode construction enable efficient heat dissipation under repeated surges.
It supports secondary lightning protection per IEC 61000-4-5 across multiple source impedances (2 Ω, 12 Ω, 42 Ω) and satisfies pin injection immunity (RTCA/DO-160F Waveform 4 Level 5 up to 300 V VWM). Standby current is ≤10 μA at VWM, and temperature coefficient of breakdown voltage is +30 mV/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - enables robust protection against lightning-induced transients without thermal runaway |
| Reverse Standoff Voltage (VWM) | 30 V - sets maximum continuous operating voltage before clamping activation |
| Clamping Voltage (VC) | ≤48.8 V @ IPP = 738 A - limits downstream voltage stress during worst-case surge events |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - allows direct mounting to heatsink for sustained multi-pulse operation |
| Breakdown Voltage (V(BR)) | 33.3–36.8 V @ 5 mA - defines precise turn-on threshold with tight tolerance band |
| Standby Current (ID) | ≤10 μA @ 30 V - ensures negligible leakage in standby, critical for low-power avionics |
| Temperature Coefficient (αV(BR)) | +30 mV/°C - quantifies predictable V(BR) drift over -55°C to +150°C operating range |
Pinout & Package
MXLPLAD36KP30CAE3 uses a surface-mount PLAD package with metal base cathode (pin 1) and anode (pin 2) terminals. The low-profile void-free epoxy body (12.32 × 10.54 × 5.08 mm) mounts directly to PCB copper for thermal conduction. Polarity marking is present only on unidirectional variants; this bidirectional part has symmetric terminal function.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal Base (Bottom Surface) | Cathode / Anode (Bidirectional) | Provides dual-polarity clamping path; serves as primary thermal interface to PCB heatsink |
| Top Metal Pad (Anode Side) | Anode / Cathode (Bidirectional) | Completes symmetrical surge path; soldered to trace for mechanical and electrical connection |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping architecture | Protects AC-coupled and floating signal lines without polarity constraints |
| AEC-Q101 qualified and MIL-PRF-19500 upscreenable | Supports automotive and aerospace deployment with traceable wafer/assembly lots |
| RTCA DO-160F Waveform 4 Level 5 compliance | Validated for aircraft pin-injection immunity up to 300 V VWM devices (including MXLPLAD36KP30CAE3) |
| Moisture Sensitivity Level 1 | Eliminates dry-pack requirement and floor-life limitations per J-STD-020B |
| RoHS-compliant e3 matte-tin plating | Ensures reliable solderability and long-term intermetallic stability in lead-free reflow |
Applications
| Aircraft Avionics Power Input | Automotive Load Dump Protection |
|---|---|

IC Role / Device Role / Timing Role: Secondary lightning protector meeting Class 4 thresholds for long-distance cable runs (≤130 V VWM max). Use Value: MXLPLAD36KP30CAE3's 30 V VWM falls within the MPLAD36KP14A–130CA range certified for this configuration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30CA | Lower PPP (600 W), smaller SMB package, higher RθJA (50 °C/W), no AEC-Q101 or DO-160 qualification | Suitable for consumer-grade industrial controls but not certified for aerospace lightning standards | Select when cost and board space constrain design and full DO-160/IEC 61000-4-5 compliance is unnecessary |
| SMCJ33CA | Higher VWM (33 V), same 36 kW PPP, SMC package with RθJC ≈ 1.5 °C/W, AEC-Q101 qualified but not DO-160 tested | Meets automotive load dump but lacks RTCA DO-160F Waveform 4 Level 5 validation | Choose for automotive ECUs needing tighter VWM margin over 30 V nominal rails, with verified surge endurance |
Compared with SMBJ30CA and SMCJ33CA, MXLPLAD36KP30CAE3 uniquely combines 36 kW surge capability, DO-160F certification, MIL-PRF-19500 upscreening readiness, and 1.0 °C/W thermal resistance-making it irreplaceable in safety-critical airborne systems where multi-stroke lightning resilience is mandated.

FAQ
What is the clamping voltage specification for MXLPLAD36KP30CAE3?
The MXLPLAD36KP30CAE3 has a maximum clamping voltage (VC) of 48.8 V at 738 A peak pulse current under 10/1000 μs waveform conditions. This value is guaranteed across the full operating temperature range and reflects worst-case performance used for downstream circuit protection margining.
Is MXLPLAD36KP30CAE3 certified for RTCA DO-160 lightning testing?
Yes, MXLPLAD36KP30CAE3 is validated for RTCA DO-160F Section 22 multi-stroke lightning testing, including Waveform 4 (6.4/69 μs) Level 5 compliance for devices with VWM up to 300 V. Its 30 V rating places it within the certified range for Level 5 pin injection immunity.
Does MXLPLAD36KP30CAE3 require dry pack handling per J-STD-020B?
No, MXLPLAD36KP30CAE3 is rated Moisture Sensitivity Level 1 (MSL-1) per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life and does not require dry pack packaging or baking prior to assembly-reducing manufacturing overhead and moisture-related reliability risks.
What thermal interface is required to sustain repeated 36 kW surges on MXLPLAD36KP30CAE3?
To sustain repeated 36 kW surges, MXLPLAD36KP30CAE3 must be mounted on FR4 PCB using the recommended pad layout (11.94 × 5.85 mm) with direct thermal contact to internal or external copper planes. Its 1.0 °C/W RθJC rating assumes optimal heatsinking; insufficient copper area will cause junction overheating and premature failure.
How does the bidirectional construction of MXLPLAD36KP30CAE3 affect its circuit placement?
The bidirectional construction of MXLPLAD36KP30CAE3 eliminates polarity sensitivity, allowing placement across AC-coupled lines, differential buses, or floating grounds without orientation concerns. Unlike unidirectional TVS diodes, it provides symmetrical clamping in both directions, simplifying layout and reducing BOM count in balanced signal paths.
