Product details
Overview
MPLAD36KP36CA/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 36 V working standoff voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), and 58.1 V clamping voltage (VC) at 620 A peak impulse current - designed for lightning and load dump protection in aerospace and automotive power rails.
For engineers reviewing the MPLAD36KP36CA/TR datasheet, MPLAD36KP36CA/TR pinout, MPLAD36KP36CA/TR application, or MPLAD36KP36CA/TR equivalent, this device delivers verified RTCA DO-160 Section 22 multi-stroke lightning compliance, AEC-Q101 qualification, and IEC 61000-4-5 Class 4/5 secondary surge protection with 42 Ω source impedance - critical for high-reliability avionics and 12/24 V vehicle ECUs.
Technical Context
This bidirectional TVS uses silicon avalanche diode architecture to clamp transients within nanoseconds: clamping response time <5 ns, forward surge current rating of 1500 A (8.3 ms half-sine), and thermal resistance junction-to-case of 1.0 °C/W enabling efficient heat transfer to PCB copper pads. Its PLAD package integrates a metal base cathode for low-inductance current path and minimal thermal resistance.
It meets stringent reliability requirements including 3σ lot norm screening on standby current (ID ≤ 10 µA at VWM), moisture sensitivity level 1 (no dry pack required), and full wafer/assembly lot traceability - supporting MIL-PRF-19500 upscreening options for defense-grade deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous DC or repetitive peak reverse voltage before conduction; matches nominal 24 V automotive systems with margin. |
| VBR @ IBR=5 mA | 40.0–44.2 V - breakdown threshold range ensures reliable turn-on above normal operating transients but below system damage thresholds. |
| VC @ IPP=620 A | 58.1 V - clamped voltage during worst-case 10/1000 μs surge; limits downstream IC stress to safe levels in 24 V rail protection. |
| IPP | 620 A - peak non-repetitive surge current capability at rated waveform; validated per IEC 61000-4-5 and RTCA DO-160G Waveform 4/5A. |
| PPP | 36,000 W - peak pulse power handling at 10/1000 μs; enables single-device protection against severe lightning-induced surges. |
| RθJC | 1.0 °C/W - low junction-to-case thermal resistance allows effective heat sinking through metal base to PCB copper pour or heatsink. |
| TJ/TSTG | –55 to +150 °C - extended temperature range supports operation in engine bay, avionics bays, and industrial control enclosures. |
Pinout & Package
The MPLAD36KP36CA/TR uses the PLAD surface-mount package: void-free UL94V-0 epoxy body with metal base cathode terminal, tin-plated terminals, and polarity marked by cathode on the bottom metal surface. Weight is ~1.7–2.0 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Top Surface) | Transient current entry point in bidirectional mode | Connects to protected line; symmetric conduction allows AC or dual-polarity DC surge suppression without orientation dependency. |
| Cathode (Metal Base) | Common return path and thermal interface | Serves as primary heat sink contact; must be soldered to large copper pad or thermal plane for RθJC = 1.0 °C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction (CA suffix) | Enables symmetrical clamping for AC-coupled lines or dual-rail systems without polarity constraints - essential for CAN bus, RS-485, and aircraft data buses. |
| AEC-Q101 qualified | Validated for automotive under-hood applications including ECU power inputs, battery management, and ADAS sensor interfaces with zero early-life failure risk. |
| RTCA DO-160G Section 22 compliant | Passes multi-stroke lightning test (Waveform 4 & 5A) - required for FAA/EASA certification of commercial and military avionics equipment. |
| Moisture Sensitivity Level 1 | No dry pack or baking required before reflow; compatible with standard SMT assembly lines without process modification or yield loss. |
| 3σ lot norm screening on ID | Ensures consistent leakage performance (<10 µA at 36 V); eliminates field failures due to premature conduction in high-impedance monitoring circuits. |
Applications
| Aerospace Power Distribution | Automotive Battery Management |

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 | Lower peak power (600 W), smaller SMB package, higher clamping ratio (VC/VWM = 1.78 vs. 1.61), no AEC-Q101 or DO-160G validation. | Suitable for consumer-grade 24 V IoT gateways but insufficient for automotive ECU or avionics certification testing. | Select SMBJ36CA only for cost-sensitive, non-certified applications where surge threat level is limited to IEC 61000-4-4 EFT. |
| SMCJ36CA | Higher peak power (1500 W), same SMC package footprint, clamping voltage 59.0 V at 38.9 A, not tested to RTCA DO-160G or AEC-Q101. | Meets basic IEC 61000-4-5 Class 3 but lacks multi-stroke lightning validation and lot-level screening for mission-critical use. | Choose SMCJ36CA for industrial PLC I/O modules requiring moderate surge margin but no aviation or automotive qualification. |
Compared with SMBJ36CA and SMCJ36CA, the MPLAD36KP36CA/TR delivers 24× and 24× higher peak pulse power respectively, along with certified aerospace and automotive qualification - making it the only option for designs requiring DO-160G Section 22 or ISO 7637-2 Pulse 5a compliance without derating or paralleling.

FAQ
What is the clamping voltage of MPLAD36KP36CA/TR at its rated peak pulse current?
The MPLAD36KP36CA/TR has a maximum clamping voltage (VC) of 58.1 V when subjected to its rated peak impulse current (IPP) of 620 A at the 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that downstream circuitry remains below destructive voltage thresholds during surge events - a key parameter for protecting 24 V automotive and avionics electronics.
Is MPLAD36KP36CA/TR qualified for automotive applications?
Yes, the MPLAD36KP36CA/TR is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and surge robustness required for automotive under-hood and chassis-mounted electronic control units. Its 36 V VWM, 58.1 V clamping, and 620 A IPP make it suitable for ISO 7637-2 Pulse 5a load dump protection in 12 V and 24 V vehicle systems.
Does MPLAD36KP36CA/TR meet RTCA DO-160G lightning protection requirements?
Yes, the MPLAD36KP36CA/TR is explicitly validated for RTCA DO-160G Section 22 multi-stroke lightning testing, including Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs). It achieves Level 4 and Level 5 compliance for pin injection protection - a requirement for FAA/EASA certification of commercial aircraft avionics and flight control systems.
What is the thermal resistance and recommended mounting for MPLAD36KP36CA/TR?
The MPLAD36KP36CA/TR has a junction-to-case thermal resistance (RθJC) of 1.0 °C/W, achieved only when the metal base cathode is soldered to a minimum 1.5 cm² copper pad on FR4 with 1 oz Cu. This thermal path is essential to sustain repeated 36 kW surges without junction overheating - improper pad layout increases RθJA to 50 °C/W and risks thermal runaway.
How does the bidirectional CA suffix affect the circuit implementation of MPLAD36KP36CA/TR?
The "CA" suffix denotes bidirectional construction, meaning the MPLAD36KP36CA/TR conducts symmetrically in both polarities - eliminating orientation sensitivity during placement and enabling use on AC-coupled or floating differential lines such as CAN FD, RS-485, and MIL-STD-1553 buses. Unlike unidirectional variants, it requires no anode/cathode alignment and provides identical clamping behavior regardless of surge polarity.
