Product details
Overview
MPLAD36KP130CA from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace and automotive systems. It delivers 36 kW peak pulse power at 10/1000 μs, features a 130 V reverse standoff voltage (VWM), clamps transients to ≤209 V at 173 A peak pulse current (IPP), and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MPLAD36KP130CA datasheet, MPLAD36KP130CA pinout, MPLAD36KP130CA application, or MPLAD36KP130CA equivalent, this device is selected for secondary lightning protection per IEC 61000-4-5 (2 Ω source impedance, Class 4), pin injection protection per RTCA/DO-160F Waveform 4 Level 5 (up to 300CA), and high-reliability avionics power bus protection where thermal resistance must be minimized.
Technical Context
This TVS diode operates in bidirectional mode with symmetrical breakdown behavior, enabling suppression of both positive and negative polarity transients without external polarity management. Its low RθJC of 1.0 °C/W and void-free thermosetting epoxy package support high-duty-cycle surge handling when mounted on FR4 with recommended pad layout.
It is characterized for operation across –55 °C to +150 °C junction temperature range and undergoes 100% surge testing per MIL-STD-750 Method 3019. Standby current ID is ≤10 μA at VWM, and temperature coefficient αV(BR) is +157 mV/°C - critical for stable clamping under thermal stress in engine bay or avionics bays.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - sustains aircraft lightning-induced surges without failure |
| Reverse Standoff Voltage (VWM) | 130 V - maximum continuous operating voltage before conduction begins |
| Breakdown Voltage (V(BR)) | 144–159 V @ 5 mA - ensures reliable turn-on margin above VWM for robust triggering |

FAQ
What is the clamping voltage of MPLAD36KP130CA at its rated peak pulse current?
The MPLAD36KP130CA exhibits a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current of 173 A under the standard 10/1000 μs waveform. This value is measured at TJ = 25 °C and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MPLAD36KP130CA maintains this clamping performance across its qualified operating temperature range when properly mounted per the recommended pad layout.
Does MPLAD36KP130CA meet RTCA DO-160F lightning test requirements?
Yes, the MPLAD36KP130CA is explicitly rated for RTCA DO-160F Section 22 multi-stroke lightning testing and supports Waveform 4 (6.4/69 μs) Level 5 protection up to 300CA versions. For the MPLAD36KP130CA, this translates to validated performance at 130 V standoff with full compliance documentation available in Microsemi's RF01216 Rev B datasheet. The MPLAD36KP130CA achieves this via low RθJC and symmetrical bidirectional structure.
What is the thermal resistance specification for MPLAD36KP130CA, and why does it matter?
The MPLAD36KP130CA has a junction-to-case thermal resistance (RθJC) of 1.0 °C/W, measured under defined mounting conditions on FR4 with the specified pad layout. This low value enables rapid heat extraction from the silicon die into the PCB copper or heatsink, preventing thermal runaway during repetitive surge events. For the MPLAD36KP130CA, this directly supports its 36 kW PPP rating and sustained operation in avionics power modules where ambient temperatures exceed 85 °C.
Can MPLAD36KP130CA be used in place of unidirectional TVS diodes like MPLAD36KP130A?
No - the MPLAD36KP130CA is a bidirectional device with symmetrical clamping characteristics, while the MPLAD36KP130A is unidirectional and conducts only in reverse bias. Substituting the MPLAD36KP130CA for the MPLAD36KP130A may cause unintended forward conduction in DC-biased circuits. The CA suffix denotes bidirectionality; the MPLAD36KP130CA must be used only where bidirectional protection is required, such as AC lines or floating buses.
Is RoHS compliance confirmed for MPLAD36KP130CA, and how is it marked?
Yes, the MPLAD36KP130CA is RoHS compliant and marked with the "e3" suffix in its full part number per Microsemi's nomenclature guide. This indicates annealed matte-tin plating meeting J-STD-020B Level 1 moisture sensitivity, with no dry pack required. The RoHS-compliant version uses lead-free terminations and conforms to EU Directive 2011/65/EU, verified through material declarations and process audits - a requirement for MPLAD36KP130CA deployment in modern aerospace and industrial supply chains.
