Product details
Overview
MPLAD36KP60AE3 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, features a 60 V reverse standoff voltage (VWM), clamps to ≤96.8 V at 372 A peak pulse current (IPP), and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MPLAD36KP60AE3 datasheet, MPLAD36KP60AE3 pinout, MPLAD36KP60AE3 application, or MPLAD36KP60AE3 equivalent, key selection criteria include its 60 V VWM rating, 1.0 °C/W junction-to-case thermal resistance, RoHS-compliant e3 termination, and suitability for secondary lightning protection per IEC 61000-4-5 with 42 Ω, 12 Ω, and 2 Ω source impedances.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuitry, activating above its 60 V standoff voltage to divert surge energy to ground. Its low RθJC of 1.0 °C/W enables effective heat transfer to an external heatsink when mounted per recommended pad layout on FR4 PCB.
It is rated for bidirectional variants (CA suffix) but MPLAD36KP60AE3 is unidirectional, with cathode on the metal base. It complies with AEC-Q101 stress testing and supports MIL-PRF-19500 upscreening options for high-reliability programs requiring lot traceability and 3σ standby current screening.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous operating voltage before clamping begins; must exceed system peak DC or AC voltage. |
| V(BR) min/max | 66.7–73.7 V @ 5 mA - Confirmed breakdown range ensures reliable turn-on margin above VWM. |
| VC @ IPP | ≤96.8 V @ 372 A - Clamping voltage under full 10/1000 μs surge; defines maximum voltage seen by protected ICs. |
| PPP | 36,000 W @ 10/1000 μs - Peak pulse power handling capacity; validated per Figure 1 waveform. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; enables direct heatsink mounting for sustained multi-pulse operation. |
| ID @ VWM | ≤10 μA - Standby leakage current at 60 V; negligible power loss in always-on protection circuits. |
| αV(BR) | 72 mV/°C - Temperature coefficient of breakdown voltage; used to derate V(BR) over -55°C to +150°C range. |

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 | 600 W PPP rating, SMC package, RθJC ≈ 12 °C/W, IPP = 33.3 A | Not suitable for DO-160 multi-stroke or IEC 61000-4-5 Class 4/5; limited to low-energy ESD/EFT. | Select SMBJ60A only for cost-sensitive consumer-grade designs with <1 kW surge exposure. |
| SMCJ60A | 1500 W PPP rating, SMC package, RθJC ≈ 10 °C/W, IPP = 166 A | Supports basic IEC 61000-4-5 Class 3 (42 Ω), but fails Class 4/5 and DO-160 Waveform 4/5A testing. | Choose SMCJ60A for industrial controls needing moderate surge headroom but no aerospace qualification. |
Compared with SMBJ60A and SMCJ60A, MPLAD36KP60AE3 provides 24× and 24× higher peak pulse power respectively, enabling single-device compliance with aviation lightning standards and automotive load dump-where lower-rated alternatives require parallel staging or fail outright.

FAQ
What is the clamping voltage of MPLAD36KP60AE3 at its rated peak pulse current?
The MPLAD36KP60AE3 has a maximum clamping voltage (VC) of 96.8 V at 372 A peak pulse current (IPP) under 10/1000 μs waveform conditions. This value is guaranteed per datasheet Figure 3 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MPLAD36KP60AE3 maintains this clamping performance across its full operating temperature range when properly mounted.
Does MPLAD36KP60AE3 meet AEC-Q101 qualification requirements?
Yes, MPLAD36KP60AE3 is tested and qualified to AEC-Q101 standards for discrete semiconductors. This includes stress tests for temperature cycling, humidity bias, mechanical shock, and surge robustness-validating its suitability for automotive powertrain and chassis applications. The MPLAD36KP60AE3 qualification report is available upon request from Microchip's product support team.
How is thermal management implemented for MPLAD36KP60AE3 in high-duty-cycle applications?
MPLAD36KP60AE3 relies on its 1.0 °C/W junction-to-case thermal resistance and metal-base cathode for direct thermal conduction. For high-duty-cycle or multi-stroke operation, it must be soldered to a minimum 11.94 mm × 5.85 mm copper pad (per datasheet pad layout) and thermally coupled to an external heatsink. Steady-state power dissipation is limited to 2.5 W at 25°C ambient, derating linearly above that temperature.
Can MPLAD36KP60AE3 be used for bidirectional surge protection?
No-MPLAD36KP60AE3 is a unidirectional TVS diode, with polarity marked by cathode on the metal base. For bidirectional protection at 60 V standoff, the correct variant is MPLAD36KP60CA. Using MPLAD36KP60AE3 in AC or floating signal paths will result in forward conduction during negative half-cycles and potential failure. Always match polarity suffix (A vs CA) to circuit topology.
What RTCA DO-160 lightning test levels does MPLAD36KP60AE3 support?
MPLAD36KP60AE3 supports RTCA DO-160F Section 22 Pin Injection Waveform 4 (6.4/69 μs) up to Level 4 and Waveform 5A (40/120 μs) up to Level 4, as confirmed in the RF01216 Rev B datasheet. It also meets multi-stroke lightning requirements when used with appropriate upstream filtering and grounding. Full test reports are available through Microchip's aerospace support portal.
