Product details
Overview
MPLAD36KP15CAE3 from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace, automotive, and industrial power systems. It delivers 36 kW peak pulse power at 10/1000 μs, features a 15 V reverse standoff voltage (VWM), clamps to ≤25.8 V at 1396 A peak impulse current (IPP), and operates across –55°C to +150°C junction temperature.
For engineers reviewing the MPLAD36KP15CAE3 datasheet, MPLAD36KP15CAE3 pinout, MPLAD36KP15CAE3 application, or MPLAD36KP15CAE3 equivalent, key selection criteria include its DO-160 Section 22 multi-stroke lightning compliance, IEC 61000-4-5 Class 5 secondary lightning protection capability, low thermal resistance (RθJC = 1.0°C/W), and RoHS-compliant e3 termination plating.
Technical Context
This TVS diode uses an avalanche breakdown mechanism to clamp transient overvoltages before downstream circuitry sustains damage. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal/power lines, and its void-free thermosetting epoxy package ensures mechanical robustness under thermal cycling and vibration.
The device meets AEC-Q101 stress testing requirements and supports MIL-PRF-19500 upscreening options. Its 1.0°C/W junction-to-case thermal resistance and low-profile PLAD package enable effective heat transfer to PCB copper pads or external heatsinks when mounted per recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - withstands lightning-induced surges per RTCA DO-160 Section 22 without failure |
| Reverse Standoff Voltage (VWM) | 15 V - maximum continuous operating voltage before conduction begins; matches 12 V automotive nominal systems with margin |
| Breakdown Voltage (V(BR)) | 15.6–17.2 V @ 5 mA - defines onset of avalanche conduction; ensures reliable turn-on before system overvoltage threshold |
| Clamping Voltage (VC) | ≤25.8 V @ IPP = 1396 A - limits voltage seen by protected ICs during worst-case surge; critical for 24 V logic interface survival |
| Thermal Resistance (RθJC) | 1.0 °C/W - enables efficient heat extraction to heatsink or PCB ground plane; reduces risk of thermal runaway under repeated transients |
| Junction Temperature Range | –55°C to +150°C - supports operation in engine bay, avionics bays, and industrial enclosures without derating |
| Moisture Sensitivity Level | Level 1 (per J-STD-020B) - no dry pack or bake required prior to reflow; simplifies SMT assembly logistics |
Pinout & Package
Package: PLAD (Plastic Low-profile Anode-down Device), surface-mount, void-free thermosetting epoxy body meeting UL94V-0. Cathode is the metal base (underside); polarity marking applies only to unidirectional variants - this bidirectional part (CA suffix) has no polarity marking on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (dual terminals) | Surge current path (bidirectional) | Both terminals conduct equally in either direction; connects across protected line and return (e.g., CAN_H/CAN_L, RS-485 A/B, DC bus+/–) |
| Metal base (bottom side) | Thermal conduction path | Primary heat dissipation interface; must be soldered to large copper area or heatsink for RθJC = 1.0°C/W performance |

| IEC 61000-4-5 Class 5 secondary protection (42 Ω source) | Supports long-distance wiring configurations in industrial automation - clamps induced surges below 25.8 V even at 1396 A |
| AEC-Q101 qualified | Passes accelerated stress tests including HTGB, HTRB, and TCT - confirms reliability for automotive under-hood applications |
| e3 RoHS-compliant matte-tin plating | Meets IPC/JEDEC solderability standards (MIL-STD-750 Method 2026) - ensures consistent reflow yield and intermetallic formation |
| 3σ lot norm screening on standby current (ID) | Guarantees ID ≤300 μA @ VWM = 15 V - prevents excessive leakage in battery-backed or low-power monitoring circuits |
Applications
| Aerospace Power Distribution | Automotive Load Dump Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | Lower PPP (600 W), smaller SMB package, RθJC ≈ 40°C/W | Suitable for board-level ESD/EFT only; cannot meet DO-160 Section 22 or IEC 61000-4-5 Class 5 | Select when cost and board space constrain requirements to sub-1 kW surges and ambient temperatures remain <85°C. |
| SMCJ15CA | PPP = 1500 W, larger SMC package, RθJC ≈ 15°C/W, same VWM/VC specs | Valid for IEC 61000-4-5 Class 3; insufficient for multi-stroke lightning or long-distance Class 5 | Choose for industrial PLC I/O protection where 1.5 kW surges dominate and thermal budget allows higher RθJC. |
