Product details
Overview
MPLAD36KP36AE3/TR from Microchip Technology (formerly Microsemi) is a unidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace, automotive, and industrial power rails. It delivers 36 kW peak pulse power at 10/1000 μs, clamps transients to ≤58.1 V at 620 A, and features a 36 V working standoff voltage with 40.0–44.2 V breakdown range at 5 mA - validated for RTCA DO-160 Section 22 multi-stroke lightning compliance.
For engineers reviewing the MPLAD36KP36AE3/TR datasheet, MPLAD36KP36AE3/TR pinout, MPLAD36KP36AE3/TR application, or MPLAD36KP36AE3/TR equivalent, key selection criteria include its 1.0 °C/W junction-to-case thermal resistance, <100 ps clamping response time, AEC-Q101 qualification, RoHS-compliant e3 finish, and PLAD package suitability for high-current PCB layouts requiring minimal thermal impedance.
Technical Context
This TVS diode operates in avalanche breakdown mode to divert high-energy transients away from sensitive downstream circuitry. Its low RθJC (1.0 °C/W) enables effective heat transfer to an external heatsink or copper pour, supporting sustained surge handling without thermal runaway under repeated 10/1000 μs waveforms.
The device exhibits a temperature coefficient of breakdown voltage (αVBR) of +38 mV/°C and maintains stable clamping performance across –55 °C to +150 °C junction temperature range. Its unidirectional polarity and cathode-on-base construction require correct orientation during placement on FR4 boards with recommended pad layout per Figure 7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 36,000 W - supports single-event lightning surge immunity per IEC 61000-4-5 and RTCA DO-160G Waveform 4/5A |
| Working Standoff Voltage (VWM) | 36 V - matches nominal 24 V DC systems with margin for ripple and tolerance |
| Breakdown Voltage (VBR) | 40.0–44.2 V at 5 mA - ensures reliable turn-on before damage threshold of protected ICs |
| Max Clamping Voltage (VC) | 58.1 V at 620 A - limits voltage seen by downstream MOSFETs or controllers during surge |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - enables direct thermal coupling to heatsink or large copper area for duty-cycle derating |
| Clamping Response Time | <100 ps - faster than most system-level ESD events, ensuring protection before IC latch-up |
| Standby Leakage Current | ≤10 µA at 36 V - negligible power loss in always-on 24 V rail monitoring circuits |
Pinout & Package
The MPLAD36KP36AE3/TR uses the PLAD surface-mount package: a rectangular, void-free thermosetting epoxy body (UL94V-0), with cathode terminal on the metal base (bottom side) and anode on the top-side metallized pad. Weight is ~1.7–2.0 g. Tape-and-reel packaging denoted by "TR" suffix conforms to EIA-481-B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Top Pad) | Positive input node for unidirectional surge path | Connected to protected line (e.g., 24 V supply rail); must be routed with low-inductance trace |
| Cathode (Metal Base) | Surge return path to ground or chassis | Requires direct thermal and electrical connection to large copper pour or heatsink for RθJC optimization |
Key Features
| Feature | Design Value |
|---|---|

| RTCA DO-160G Section 22 compliant | Passes multi-stroke lightning test (Waveform 4 & 5A) required for avionics power distribution units |
| Moisture Sensitivity Level 1 | No dry pack or baking required before reflow - simplifies SMT assembly and reduces handling cost |
| RoHS-compliant e3 finish | Matte-tin plating meets JEDEC J-STD-020D.1 - ensures solderability and long-term intermetallic stability |
| 3σ lot norm screening on ID | Guarantees ≤10 µA leakage across production lots - critical for battery-backed or low-power monitoring circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | Lower PPP (600 W), higher VC (58.1 V @ 10.3 A), SMB package with RθJA = 110 °C/W | Suitable only for low-duty-cycle, low-energy transients - not rated for DO-160G multi-stroke or load dump | Select MPLAD36KP36AE3/TR when >1 kW surge energy, thermal management, or aerospace qualification is required. |
| SMCJ36A | PPP = 1500 W, VC = 58.1 V @ 25.8 A, SMC package with RθJC = 2.5 °C/W | Supports moderate surge repetition but lacks AEC-Q101 and DO-160G validation; limited to industrial use | Choose MPLAD36KP36AE3/TR for certified reliability in safety-critical or high-repetition environments. |
Compared with SMBJ36A and SMCJ36A, the MPLAD36KP36AE3/TR delivers 24× and 24× higher peak pulse power respectively, achieves 2.5× better thermal conduction via its metal-base PLAD package, and carries formal AEC-Q101 and DO-160G certifications - making it the only option for certified aerospace and automotive load dump designs.

FAQ
What is the clamping voltage of the MPLAD36KP36AE3/TR at its rated peak pulse current?
The MPLAD36KP36AE3/TR has a maximum clamping voltage (VC) of 58.1 V at 620 A peak pulse current (10/1000 μs waveform). This value is measured under standardized surge conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The low clamping ratio (VC/VBR ≈ 1.45) ensures effective protection of 60 V-rated components without overdesigning downstream voltage tolerances. MPLAD36KP36AE3/TR maintains this specification across its full operating temperature range.
Is the MPLAD36KP36AE3/TR suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the MPLAD36KP36AE3/TR is explicitly AEC-Q101 qualified per the manufacturer's datasheet Revision B. It has undergone temperature cycling, highly accelerated life testing (HALT), and surge stress validation for automotive powertrain and body electronics. Its unidirectional polarity, 36 V working standoff, and 58.1 V clamping voltage align with ISO 7637-2 Load Dump Pulse 5a requirements. MPLAD36KP36AE3/TR is approved for under-hood and chassis-mounted locations where ambient temperatures reach 125 °C.
How does the PLAD package of the MPLAD36KP36AE3/TR improve thermal performance compared to standard SMC or SMB packages?
The PLAD package of the MPLAD36KP36AE3/TR features a metal base acting as both cathode terminal and primary thermal path, achieving a junction-to-case thermal resistance (RθJC) of just 1.0 °C/W - 2.5× lower than SMCJ36A (2.5 °C/W) and over 100× better than SMBJ36A (110 °C/W). This enables direct mounting to heatsinks or large copper areas, allowing MPLAD36KP36AE3/TR to sustain repetitive surges without thermal runaway. The design eliminates reliance on PCB traces for heat dissipation, a critical advantage in high-power automotive and aerospace systems.
Does the MPLAD36KP36AE3/TR meet RTCA DO-160G Section 22 lightning protection requirements?
Yes, the MPLAD36KP36AE3/TR is validated for RTCA DO-160G Section 22 multi-stroke lightning testing, including Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs) at Level 4 and Level 5. Its 36 kW rating, sub-100 ps response time, and low RθJC ensure compliance without auxiliary cooling. The device is listed in the datasheet as supporting Level 4 up to 400 V VWM, confirming MPLAD36KP36AE3/TR's suitability for primary and secondary lightning protection in avionics power distribution units and flight control electronics.
What is the moisture sensitivity level (MSL) and reflow profile requirement for the MPLAD36KP36AE3/TR?
The MPLAD36KP36AE3/TR is rated Moisture Sensitivity Level 1 (MSL-1) per IPC/JEDEC J-STD-020D.1, meaning it has unlimited floor life and requires no dry packing or baking prior to reflow soldering. Its maximum solder temperature is 260 °C for 10 seconds, compatible with standard lead-free reflow profiles. This eliminates moisture-related popcorning risk and simplifies manufacturing logistics - a key advantage over MSL-3 or MSL-4 TVS devices that demand strict handling controls. MPLAD36KP36AE3/TR's MSL-1 rating is confirmed in Section 1.1 of the official datasheet.
