Product details
Overview
MPLAD36KP130A 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 ≤209 V at 173 A, and features a 130 V reverse standoff voltage (VWM) with 144–159 V breakdown range (VBR). Its low-profile thermoset epoxy package enables robust lightning protection per RTCA DO-160 Section 22 and IEC 61000-4-5 Class 4 (2 Ω source).
For engineers reviewing the MPLAD36KP130A datasheet, MPLAD36KP130A pinout, MPLAD36KP130A application, or MPLAD36KP130A equivalent, this device is selected for high-reliability DC bus protection where multi-stroke lightning immunity, thermal resistance <1.0 °C/W (junction-to-case), and RoHS-compliant solderability are critical design requirements.
Technical Context
The MPLAD36KP130A operates as a silicon avalanche diode configured in unidirectional polarity, with cathode on the metal base for direct thermal coupling to PCB copper. Its clamping behavior is defined by a controlled avalanche breakdown mechanism, enabling fast response (<100 ps) and stable voltage limiting under repetitive 10/1000 μs surges at ≤0.05% duty cycle.
It supports secondary lightning protection per IEC 61000-4-5 with 2 Ω source impedance up to Class 4, and meets RTCA DO-160F Waveform 4 (6.4/69 μs) Level 4 and Waveform 5A (40/120 μs) Level 4 requirements - validated via surge testing to 1000 A due to equipment limits, with derating guidance provided for elevated ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - sustains full-rated surge energy without failure under standard test waveform |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SP36-130 | Same 130 V VWM, but lower PPP (30 kW), higher VC (220 V @ 150 A), and RθJC = 1.5 °C/W | Less suitable for multi-stroke DO-160 testing; requires larger copper area for thermal management | Select when cost sensitivity outweighs multi-pulse endurance and thermal performance requirements |
| Vishay SMAJ130A | Lower PPP (400 W), smaller SMC package, VC = 214 V @ 1.9 A - not scalable to 36 kW energy levels | Only appropriate for low-energy ESD/EFT; cannot replace MPLAD36KP130A in lightning or load dump scenarios | Use only for board-level signal-line protection, not power-rail surge suppression |
Compared with Littelfuse SP36-130 and Vishay SMAJ130A, the MPLAD36KP130A provides superior thermal dissipation (RθJC = 1.0 °C/W), verified multi-stroke lightning capability, and 90× higher peak power handling - making it the sole choice for mission-critical aerospace and heavy-duty automotive power rail protection.

FAQ
What is the clamping voltage of the MPLAD36KP130A under a 10/1000 μs surge?
The MPLAD36KP130A has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current of 173 A under the 10/1000 μs waveform. This value is measured at TJ = 25°C and reflects worst-case voltage seen by protected circuitry during standardized surge testing - critical for verifying margin against downstream component voltage ratings.
Is the MPLAD36KP130A suitable for automotive under-hood applications?
Yes, the MPLAD36KP130A is AEC-Q101 qualified and rated for junction temperatures from –55°C to +150°C. Its 130 V VWM, 36 kW surge capability, and low thermal resistance make it appropriate for protecting engine control units and powertrain modules against ISO 7637-2 load dump and coupled transients in harsh under-hood environments.
How does the MPLAD36KP130A achieve compliance with RTCA DO-160 Section 22?
The MPLAD36KP130A achieves RTCA DO-160 Section 22 compliance through verified multi-stroke lightning performance: it withstands repeated 10/1000 μs surges up to 36 kW with minimal parameter shift, supported by its low RθJC = 1.0 °C/W and optimized thermal pad layout. Test data confirms Level 4 immunity for Waveform 4 and Waveform 5A per DO-160F.
What is the polarity configuration of the MPLAD36KP130A?
The MPLAD36KP130A is a unidirectional TVS diode, with the cathode electrically and thermally connected to the metal base (bottom side of the package). The anode is accessible via the top surface pad. This configuration allows direct mounting onto heatsinks or large copper pours for optimal thermal performance in high-power surge scenarios.
Does the MPLAD36KP130A require moisture-sensitive handling?
No, the MPLAD36KP130A has IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1, meaning it does not require dry pack packaging or floor-life controls. It can be stored and processed under standard ambient conditions without baking prior to reflow soldering - simplifying manufacturing logistics and reducing assembly risk.
