Product details
Overview
MPLAD36KP30CA/TR from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) rated for 36,000 W peak pulse power at 10/1000 μs, with 30 V working standoff voltage (VWM), 33.3–36.8 V breakdown voltage (VBR), and 48.8 V clamping voltage (VC) at 738 A peak impulse current. It is designed for secondary lightning protection in avionics per RTCA DO-160 Section 22 and IEC 61000-4-5.
For engineers reviewing the MPLAD36KP30CA/TR datasheet, MPLAD36KP30CA/TR pinout, MPLAD36KP30CA/TR application, or MPLAD36KP30CA/TR equivalent, this device delivers verified multi-stroke surge capability, AEC-Q101 qualification, RoHS compliance, and low thermal resistance (RθJC = 1.0 °C/W) in a PLAD package suitable for high-reliability aerospace and automotive power rail protection.
Technical Context
This bidirectional TVS operates in avalanche breakdown mode to clamp transients above its VWM threshold, with sub-5 ns response time and clamping performance validated under 10/1000 μs and 40/120 μs waveforms. Its metal-base cathode construction enables direct thermal coupling to PCB copper, supporting high-energy dissipation without external heatsinking.
The device meets IEC 61000-4-2 ESD (±30 kV contact), IEC 61000-4-4 EFT (40 A), and IEC 61000-4-5 surge (up to Class 5 with 42 Ω source) - with specific coverage confirmed for 30 V-rated variants across all listed standards. It is fully surge-tested and 3σ lot-norm screened on standby current (ID ≤ 10 µA at VWM).

Pinout & Package
The MPLAD36KP30CA/TR uses the PLAD surface-mount package: a low-profile, void-free thermosetting epoxy body with metal base acting as the cathode terminal. Dimensions are 10.3 × 8.4 × 3.2 mm (L × W × H); weight ≈ 1.8 g. Cathode is electrically and thermally connected to the exposed metal base (bottom side), anode to the top-side metallized pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal Base (Bottom) | Cathode | Primary current return path and thermal interface - must be soldered to large copper pour for effective heat sinking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33CA | Lower peak power (600 W), smaller SMB package, higher VC/VWM ratio (≈1.7×) | Suitable only for low-energy transients (e.g., ESD/EFT); not rated for DO-160 lightning or load dump | Select when cost and board space are prioritized over multi-stroke surge endurance. |
| SMCJ33CA | Higher peak power (1500 W), SMC package, same VWM/VBR range but lower IPP (100 A vs. 738 A) | Meets IEC 61000-4-5 Class 3, but insufficient for DO-160 Level 4/5 or automotive load dump | Choose for industrial I/O protection where 1.5 kW surge capacity suffices and PLAD footprint is not required. |
Compared with SMBJ33CA and SMCJ33CA, the MPLAD36KP30CA/TR delivers 24× and 24.5× higher peak pulse power respectively, enabling single-device compliance with aviation lightning standards and automotive load dump - while maintaining identical 30 V standoff and bidirectional polarity in a thermally optimized PLAD package.

FAQ
What is the clamping voltage of the MPLAD36KP30CA/TR at its rated peak pulse current?
The MPLAD36KP30CA/TR has a maximum clamping voltage (VC) of 48.8 V when subjected to its rated peak impulse current of 738 A at the 10/1000 μs waveform. This value is measured per standard test conditions in the datasheet and ensures protected circuitry remains below critical overvoltage thresholds during full-rated surge events.
Is the MPLAD36KP30CA/TR qualified for automotive applications?
Yes, the MPLAD36KP30CA/TR is AEC-Q101 qualified and explicitly rated for automotive load dump protection per ISO 7637-2 Pulse 5a. Its 30 V working standoff voltage, 48.8 V clamping, and 36,000 W surge rating make it suitable for 12 V and 24 V ECU power inputs in engine control, transmission, and ADAS modules.
Does the MPLAD36KP30CA/TR require special handling due to moisture sensitivity?
No - the MPLAD36KP30CA/TR has IPC/JEDEC J-STD-020D.1 moisture sensitivity level (MSL) 1, meaning it can be stored indefinitely at ambient conditions and requires no dry packing or baking prior to reflow soldering. This simplifies manufacturing logistics and eliminates moisture-related assembly risks.
How does the PLAD package of the MPLAD36KP30CA/TR improve thermal performance?
The PLAD package uses a metal base as the cathode terminal, providing direct thermal conduction from the silicon die to the PCB copper. With a junction-to-case thermal resistance (RθJC) of just 1.0 °C/W, the MPLAD36KP30CA/TR efficiently dissipates heat during repetitive surge events - a key advantage over plastic-packaged TVS diodes with RθJC > 10 °C/W.
Can the MPLAD36KP30CA/TR be used for RTCA DO-160G lightning testing?
Yes, the MPLAD36KP30CA/TR is explicitly validated for RTCA DO-160G Section 22 lightning-induced transient testing, including Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) at Level 4.
