Product details
Overview
MPLAD36KP60A from Microsemi is a unidirectional 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, clamps transients to ≤96.8 V at 372 A, and operates with 60 V reverse standoff voltage (VWM). Its low-profile thermoset epoxy package minimizes thermal resistance and supports RTCA DO-160 Section 22 multi-stroke lightning compliance.
For engineers reviewing the MPLAD36KP60A datasheet, MPLAD36KP60A pinout, MPLAD36KP60A application, or MPLAD36KP60A equivalent, key selection criteria include its 60 V VWM, 372 A IPP, 96.8 V VC clamping, unidirectional polarity, and AEC-Q101 qualification - critical for load dump and secondary lightning protection in avionics and vehicle ECUs.
Technical Context
The MPLAD36KP60A employs a silicon avalanche diode structure optimized for fast response (<100 ps) and high cumulative energy handling. Its thermal design features a metal-base cathode for direct heat sinking and RθJC = 1.0 °C/W, enabling stable operation under repetitive surges at ≤0.05% duty factor on FR4 PCBs with recommended pad layout.
It meets IEC 61000-4-5 (Class 1–5, 2–42 Ω source), IEC 61000-4-2/4-4 (ESD/EFT), and RTCA DO-160F Waveform 4 & 5A pin injection standards. Standby current is screened to 3σ lot norm, and moisture sensitivity is IPC/JEDEC Level 1 - eliminating dry-pack requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V maximum working standoff voltage - ensures reliable blocking during normal 48–60 V system operation without leakage-induced stress. |
| VBR min/max | 66.7–73.7 V breakdown range at 5 mA - guarantees predictable avalanche initiation above operating voltage with tight process control. |
| VC @ IPP | ≤96.8 V clamping voltage at 372 A peak pulse - limits downstream IC voltage stress during 36 kW transients per 10/1000 μs waveform. |
| IPP | 372 A peak impulse current - enables robust protection against automotive load dump (ISO 7637-2 Pulse 5a) and lightning-induced surges. |
| RθJC | 1.0 °C/W junction-to-case thermal resistance - allows direct mounting to heatsink for sustained multi-pulse reliability without derating. |
| TJ/TSTG | −55 to +150 °C operating/storage range - supports deployment in engine bay, avionics bays, and industrial enclosures with wide ambient swings. |
Pinout & Package
Package: PLAD - void-free UL94V-0 thermosetting epoxy body with metal base cathode; dimensions 12.32 × 10.54 × 5.08 mm (L × W × H); weight ≈1.85 g; RoHS-compliant matte-tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal for unidirectional conduction | Connected to protected line; conducts only during reverse overvoltage events - isolates normal forward bias operation. |
| Cathode (Metal Base) | Ground-reference terminal / heat sink interface | Mounted directly to PCB copper pour or heatsink; serves dual role as electrical return and primary thermal path (RθJC = 1.0 °C/W). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood applications including temperature cycling, humidity, and mechanical shock per JESD22 standards. |
| RTCA DO-160F Waveform 4 & 5A compliant | Withstands 6.4/69 μs and 40/120 μs pin-injection transients up to Level 5 (≤300 V VWM) - certified for aircraft flight-critical subsystems. |
| IEC 61000-4-5 Class 5 support (42 Ω source) | Meets highest secondary lightning immunity for long-distance wiring harnesses - verified at 60 V VWM with 372 A IPP. |
| Low-profile SMT package with metal base | Enables automated assembly while delivering thermal performance comparable to through-hole TVS devices - no layout redesign needed. |
| 3σ lot-norm screening on ID | Ensures <10 μA standby current across production lots - prevents battery drain in always-on vehicle modules and avionics power rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A | Lower PPP (600 W), smaller SMB package, RθJC = 11.5 °C/W, VC = 96.8 V @ 6.5 A | Suitable for low-energy ESD/EFT only; cannot handle load dump or lightning surges. | Select only for cost-sensitive consumer electronics where 36 kW capability is unnecessary. |
| SMCJ60A | Higher PPP (1500 W), larger SMC package, RθJC = 3.5 °C/W, VC = 96.8 V @ 15.4 A | Supports moderate automotive transients but fails RTCA DO-160 multi-stroke testing beyond 5–10 shots. | Use where space permits and full 36 kW multi-stroke endurance is not required - e.g., non-safety-critical modules. |
Compared with SMBJ60A and SMCJ60A, the MPLAD36KP60A provides 24× and 24× higher peak pulse power respectively, validated for >100 lightning strokes and AEC-Q101 stress - making it the sole choice for mission-critical aerospace and heavy-duty automotive power protection.

FAQ
What is the maximum clamping voltage of the MPLAD36KP60A at its rated peak pulse current?
The MPLAD36KP60A has a maximum clamping voltage (VC) of 96.8 V when subjected to its rated peak pulse current of 372 A under the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures downstream circuitry remains within safe voltage limits during high-energy transients.
Is the MPLAD36KP60A suitable for automotive underhood applications?
Yes, the MPLAD36KP60A is AEC-Q101 qualified and rated for −55 to +150 °C junction temperature, making it suitable for underhood automotive applications. Its 372 A IPP and 36 kW PPP rating meet ISO 7637-2 Pulse 5a load dump requirements, and its metal-base thermal design supports reliable operation on engine control units without external heatsinking.
Does the MPLAD36KP60A require dry pack packaging per J-STD-020B?
No, the MPLAD36KP60A has IPC/JEDEC moisture sensitivity level (MSL) 1, meaning it does not require dry pack packaging or baking prior to reflow soldering. Its void-free thermoset epoxy body and RoHS-compliant matte-tin plating ensure robust manufacturability in standard SMT processes without moisture-related defects.
How does the MPLAD36KP60A achieve compliance with RTCA DO-160 Section 22?
The MPLAD36KP60A achieves RTCA DO-160 Section 22 compliance through its 36 kW peak pulse power rating, sub-100 ps response time, and validated multi-stroke endurance (>100 shots at 10/1000 μs). Its thermal design (RθJC = 1.0 °C/W) prevents cumulative heating failure during repeated lightning transients - a key requirement for aircraft power system certification.
What is the polarity configuration and cathode identification for the MPLAD36KP60A?
The MPLAD36KP60A is a unidirectional TVS diode with cathode located on the metal base (underside) of the package. The anode is the top-side metallized surface. Polarity is marked on the device body per Microsemi specification, and correct orientation must be maintained during PCB layout to ensure proper clamping direction on the protected line.
