Product details
Overview
MPLAD36KP15AE3/TR from Microsemi (now Microchip) is a unidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace, automotive, and industrial power rails. It features a 15 V working standoff voltage (VWM), 24.0 V maximum clamping voltage (VC) at 3000 A peak pulse current (IPP), and 36,000 W peak pulse power rating at 10/1000 μs waveform - validated for RTCA DO-160 Section 22 multi-stroke lightning compliance.
For engineers reviewing the MPLAD36KP15AE3/TR datasheet, MPLAD36KP15AE3/TR pinout, MPLAD36KP15AE3/TR application, or MPLAD36KP15AE3/TR equivalent, key selection criteria include its low thermal resistance (RθJC = 1.0 °C/W), RoHS-compliant matte-tin plating, 1.7–2.0 g mass, and suitability for secondary lightning protection per IEC 61000-4-5 with 42 Ω, 12 Ω, or 2 Ω source impedance.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transients above its 15.6–17.2 V breakdown voltage (VBR) at 150 mA test current. Its metal-base cathode construction enables direct thermal coupling to PCB copper, supporting high-reliability mounting on FR4 with 1 oz Cu and recommended pad layout per Figure 7.
It delivers sub-100 ps response time (unidirectional), withstands 1500 A forward surge current (IFSM), and maintains <300 µA standby leakage (ID) at VWM. Derating is required above 25 °C ambient, with steady-state power dissipation dropping from 2.51 W at TA = 25 °C to 504 W at TC = 100 °C under heatsink control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - Maximum continuous DC or repetitive peak reverse voltage before conduction begins; sets minimum system operating margin. |
| VBR @ IBR | 15.6–17.2 V @ 150 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC @ IPP | 24.0 V @ 3000 A - Clamped voltage during 10/1000 μs surge; defines worst-case rail excursion seen by downstream circuitry. |
| PPP | 36,000 W - Peak pulse power handling at 10/1000 μs; validates robustness against lightning-induced surges per DO-160G Waveform 4 & 5A. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; enables efficient heat transfer to heatsink or copper pour for sustained surge duty. |
| ID @ VWM | ≤300 µA - Low leakage current at rated standoff; minimizes quiescent power loss in battery-backed or low-power systems. |
| TJ/TSTG | –55 to +150 °C - Extended temperature range supports operation in engine bays, avionics bays, and industrial enclosures. |
Pinout & Package
The MPLAD36KP15AE3/TR uses the PLAD surface-mount package: void-free UL94V-0 epoxy body with metal base cathode terminal and annealed matte-tin plated terminals. Cathode is the entire metal bottom surface; anode is the top-side metallization. Weight: 1.7–2.0 g. Tape-and-reel packaging indicated by "TR" suffix.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal Base (Bottom) | Cathode | Primary heat path and return node; must be soldered to large copper area or heatsink for thermal management. |
| Top-Side Metallization | Anode | High-current input node; connects to protected line (e.g., 12 V rail, CAN bus, sensor supply). |
Key Features
| Feature | Design Value |
|---|---|
| 36 kW Surge Rating | Validated clamping performance at 3000 A (10/1000 μs); meets DO-160G Section 22 multi-stroke lightning requirements. |
| Low RθJC = 1.0 °C/W | Enables >500 W steady-state dissipation with active heatsinking; critical for automotive load dump and repeated surge events. |
| AEC-Q101 Qualified | Qualified for automotive electronics per stress test standard - supports under-hood and powertrain applications. |
| RoHS Compliant (e3) | Matte-tin plating meets JEDEC J-STD-020D.1 Level 1 moisture sensitivity; no dry pack required prior to reflow. |
| Traceable Wafer & Assembly Lots | Full lot traceability supports aerospace configuration management and failure analysis in safety-critical systems. |
Applications
| Aerospace Power Distribution | Automotive 12 V System Protection |
|---|---|
Use Scenario: Protecting avionics power inputs against lightning-induced transients per RTCA DO-160G Section 22 Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs). IC Role / Device Role / Timing Role: Primary clamping device on main 28 V DC bus or auxiliary 12 V distribution lines. Use Value: Withstands ≥3000 A surges while limiting clamped voltage to 24.0 V - preserving downstream regulators and FPGAs. |
Use Scenario: Secondary protection on vehicle battery feed lines subjected to ISO 7637-2 Load Dump (12 V systems). IC Role / Device Role / Timing Role: High-energy TVS placed upstream of DC-DC converters and ECU power supplies. Use Value: 36,000 W rating absorbs full load dump energy without degradation; AEC-Q101 qualification ensures reliability across temperature cycles. |
| Industrial Motor Drive DC Bus | Telecom Power Interface |
Use Scenario: Safeguarding 24–48 V DC bus in variable-frequency drives against switching transients and inductive kickback. IC Role / Device Role / Timing Role: Parallel-connected TVS across bus rails to clamp voltage spikes during IGBT commutation. Use Value: Sub-100 ps response time ensures clamping initiates before MOSFET/IGBT gate oxide damage thresholds are exceeded. |
Use Scenario: Protecting PoE-powered equipment (IEEE 802.3af/at) from induced surges on Ethernet power pairs. IC Role / Device Role / Timing Role: Bidirectional-capable variant (e.g., MPLAD36KP15CAE3/TR) used on 48 V DC input rails. Use Value: 24.0 V clamping at 3000 A prevents latch-up in PMICs and Ethernet PHYs during IEC 61000-4-5 Class 4 tests. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | Lower 600 W PPP, 24.4 V VC @ 22.5 A IPP; SMC package; no AEC-Q101 or DO-160 qualification. | Limited to consumer-grade or non-safety-critical 12 V circuits; insufficient for load dump or lightning standards. | Select only for cost-sensitive, low-energy applications where 36 kW rating is unnecessary. |
| SMCJ15A | 1500 W PPP, 24.4 V VC @ 62.5 A IPP; same SMC package; AEC-Q101 qualified but not DO-160 tested. | Suitable for basic automotive ESD/EFT (IEC 61000-4-2/4-4), but cannot meet DO-160G Section 22 or IEC 61000-4-5 Class 4/5. | Choose when DO-160 compliance is not required and board space allows larger SMC footprint. |
Compared with SMBJ15A and SMCJ15A, the MPLAD36KP15AE3/TR delivers 60× higher surge power handling, certified DO-160G lightning immunity, and lower thermal resistance - making it the only option for aerospace and high-reliability automotive power rail protection.

FAQ
What is the clamping voltage of MPLAD36KP15AE3/TR at its rated peak pulse current?
The MPLAD36KP15AE3/TR has a maximum clamping voltage (VC) of 24.0 V when subjected to its rated 3000 A peak pulse current (IPP) under the 10/1000 μs waveform. This value is measured per standard test conditions in the datasheet and defines the upper voltage limit imposed on protected circuitry during a full-rated surge event.
Is MPLAD36KP15AE3/TR qualified for automotive applications?
Yes, the MPLAD36KP15AE3/TR is AEC-Q101 qualified, confirming its suitability for automotive electronic systems including engine control units, body control modules, and infotainment power supplies. Its qualification covers temperature cycling, humidity testing, and mechanical shock - validating reliability in under-hood and cabin environments.
Does MPLAD36KP15AE3/TR meet RTCA DO-160G lightning protection requirements?
Yes, the MPLAD36KP15AE3/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). Its 36,000 W rating and low clamping voltage ensure compliance with Level 4 and Level 5 pin injection requirements for aircraft power and signal lines.
What is the thermal resistance junction-to-case for MPLAD36KP15AE3/TR?
The MPLAD36KP15AE3/TR has a junction-to-case thermal resistance (RθJC) of 1.0 °C/W, enabling efficient heat transfer from the silicon die to the metal base. This low value supports high-duty-cycle surge operation when mounted on a thermally optimized PCB pad or external heatsink.
How does the "E3/TR" suffix in MPLAD36KP15AE3/TR affect its specifications?
The "E3" suffix indicates RoHS-compliant matte-tin plating per JEDEC J-STD-020D.1 Level 1 moisture sensitivity - eliminating dry-pack requirements. The "TR" suffix denotes tape-and-reel packaging per EIA-481-B, enabling automated SMT placement. Neither suffix alters electrical or thermal specifications.
