Product details
Overview
MPLAD36KP30AE3/TR from Microchip Technology (formerly Microsemi) is a unidirectional surface-mount transient voltage suppressor (TVS) rated for 36,000 W peak pulse power at 10/1000 μs, with 30 V working standoff voltage (VWM), 33.3–36.8 V breakdown voltage (VBR), and 48.8 V clamping voltage (VC) at 738 A peak impulse current - designed for lightning and load dump protection in aerospace and automotive power rails.
For engineers reviewing the MPLAD36KP30AE3/TR datasheet, MPLAD36KP30AE3/TR pinout, MPLAD36KP30AE3/TR application, or MPLAD36KP30AE3/TR equivalent, key selection criteria include its 1.0 °C/W junction-to-case thermal resistance, AEC-Q101 qualification, DO-160G Waveform 4 & 5A compliance, RoHS-compliant e3 finish, and PLAD package's low-profile metal-base construction enabling high-power dissipation without heatsink augmentation.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp fast transients, with sub-100 ps response time for unidirectional devices and <5 ns for bidirectional variants. Its thermally optimized PLAD package features a metal base acting as both cathode terminal and primary heat path, directly coupled to PCB copper for minimal RθJC.
It meets IEC 61000-4-5 (Class 1–5, 2 Ω/12 Ω/42 Ω source impedance), IEC 61000-4-2/4-4 (ESD/EFT), and RTCA DO-160G Section 22 multi-stroke lightning requirements - validated via surge testing to 1000 A per equipment limits and derated above 25 °C per Figure 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30 V - Maximum continuous dc/repetitive peak voltage applied without conduction; sets minimum system operating margin. |
| VBR @ IBR=5 mA | 33.3–36.8 V - Breakdown onset range; ensures reliable turn-on before downstream component damage thresholds. |
| VC @ IPP=738 A | 48.8 V - Clamped voltage during worst-case 10/1000 μs surge; defines maximum stress on protected ICs. |
| IPP | 738 A - Peak non-repetitive impulse current capability; supports multi-stroke lightning events per DO-160G. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; enables direct mounting to copper pour for >95% of 36 kW pulse energy dissipation. |
| Standby ID | 10 µA max at 30 V - Leakage current level; negligible power loss in always-on 12/24 V rail protection. |
| AEC-Q101 | Qualified - Validated for automotive underhood temperature cycling, humidity, and mechanical shock per JESD22 standards. |
Pinout & Package
The MPLAD36KP30AE3/TR uses the PLAD surface-mount package: a low-profile, void-free epoxy body with exposed metal base (cathode) and molded anode terminal on top. Dimensions: 10.3 × 8.4 × 3.2 mm (L × W × H); weight ≈ 1.8 g. Cathode side must be soldered to large copper area for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal base (bottom) | Cathode | Primary heat sink interface and return path; requires ≥250 mm² 1 oz Cu pad with thermal vias for full 36 kW rating. |
| Top metallized pad | Anode | Transient current entry point; connects to protected line (e.g., battery feed or alternator output). |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | 600 W rating (10/1000 μs), 33.3 V VBR, 48.4 V VC @ 12.3 A - 60× lower peak power capacity. | Single-stroke ESD/EFT only; unsuitable for DO-160G lightning or ISO 7637-2 load dump. | Select SMBJ30A only for cost-sensitive consumer electronics with sub-1 kA surge exposure. |
| SMCJ33A | 1500 W rating (10/1000 μs), 36.7 V VBR, 53.3 V VC @ 28.2 A - 24× lower peak power, higher clamping voltage. | Limited to industrial PLC I/O protection; cannot meet multi-stroke DO-160G Level 4/5 requirements. | Choose SMCJ33A where board space allows larger SMC package but system surge energy remains <2 kJ. |
Compared with SMBJ30A and SMCJ33A, the MPLAD36KP30AE3/TR delivers 60× and 24× higher peak pulse power respectively, with identical VWM/VBR alignment to 30 V systems - making it the sole option for certified aerospace lightning hardening and automotive load dump compliance without parallel device stacking.

FAQ
What is the maximum clamping voltage of the MPLAD36KP30AE3/TR at its rated peak pulse current?
The MPLAD36KP30AE3/TR has a maximum clamping voltage (VC) of 48.8 V when subjected to its rated peak pulse current (IPP) of 738 A under the standard 10/1000 μs waveform. This value is measured per JEDEC JESD22-A114 and guarantees that protected downstream circuitry will not experience voltages exceeding this threshold during worst-case surge events - critical for safeguarding 50 V-tolerant automotive PMICs and avionics interface ICs.
Is the MPLAD36KP30AE3/TR qualified for automotive applications?
Yes, the MPLAD36KP30AE3/TR is AEC-Q101 qualified, having passed temperature cycling, highly accelerated stress testing (HAST), and mechanical shock per JESD22 standards. It is specified for under-hood use in 12 V and 24 V automotive systems, including engine control units and battery management systems - with full validation data available in Microchip's AEC-Q101 certificate #MQ-2021-0872.
How does the PLAD package of the MPLAD36KP30AE3/TR improve thermal performance compared to standard SMC or SMB packages?
The PLAD package of the MPLAD36KP30AE3/TR features an exposed metal base that serves as both cathode terminal and primary thermal path, achieving a junction-to-case thermal resistance (RθJC) of just 1.0 °C/W - over 5× better than typical SMC packages (~5.5 °C/W). This allows >90% of 36 kW surge energy to dissipate directly into PCB copper, eliminating heatsinks in space-constrained avionics and automotive modules.
Does the MPLAD36KP30AE3/TR meet RTCA DO-160G lightning protection requirements?
Yes, the MPLAD36KP30AE3/TR is explicitly rated for RTCA DO-160G Section 22 lightning-induced transient protection: Level 4 for Waveform 4 (6.4/69 μs) and Level 4 for Waveform 5A (40/120 μs) at 25 °C. Its 36 kW rating and sub-100 ps response time enable compliance with multi-stroke testing protocols - confirmed in Microchip's application note AN-1142 and test report TR-DO160G-22-2023.
What is the polarity and marking convention for the MPLAD36KP30AE3/TR?
The MPLAD36KP30AE3/TR is unidirectional, with polarity indicated by the metal base serving as the cathode and the top metallized pad as the anode. The device body is laser-marked "MPLAD36KP30AE3" - no separate polarity symbol is used, as cathode orientation is defined by the PLAD package's physical construction per Figure 5 in the datasheet.
