Product details
Overview
MPLAD36KP22A/TR from Microsemi (now Microchip) is a unidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace, automotive, and industrial power rails. It delivers 36,000 W peak pulse power at 10/1000 μs, clamps transients to ≤36.4 V at 990 A, and features a 22 V working standoff voltage with <100 ps response time. It is AEC-Q101 qualified and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MPLAD36KP22A/TR datasheet, MPLAD36KP22A/TR pinout, MPLAD36KP22A/TR application, or MPLAD36KP22A/TR equivalent, key selection criteria include its 22 V VWM, 24.4–26.9 V VBR, 36.4 V VC @ 990 A, thermal resistance of 1.0 °C/W (junction-to-case), and suitability for secondary lightning protection per IEC 61000-4-5 with 42 Ω source impedance up to Class 5 (short distance).
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuitry, entering avalanche breakdown when transient voltage exceeds its 24.4–26.9 V breakdown range. Its low RθJC = 1.0 °C/W enables effective heat transfer to an external heatsink, supporting sustained surge handling without thermal runaway.
It is rated for bidirectional variants (suffix "CA") but MPLAD36KP22A/TR is unidirectional, with cathode on the metal base. The device complies with IEC 61000-4-2/4-4/4-5 and RTCA/DO-160G Waveform 4 & 5A pin injection tests - validated for Level 4/5 protection across multiple voltage classes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22 V - Maximum continuous DC or repetitive peak reverse voltage before conduction begins; sets minimum system operating margin. |
| VBR @ IBR | 24.4–26.9 V @ 5 mA - Breakdown onset range; ensures reliable triggering above normal rail fluctuations. |
| VC @ IPP | 36.4 V @ 990 A - Clamped voltage during worst-case 10/1000 μs surge; defines maximum stress on downstream ICs. |
| IPP | 990 A - Peak impulse current capability; supports DO-160G Level 5 (short distance) and IEC 61000-4-5 Class 5 compliance. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; enables direct mounting to heatsink for stable multi-pulse operation. |
| Response Time | <100 ps - Enables suppression of fast-rising ESD and switching transients before damage occurs. |
| AEC-Q101 | Qualified - Validated for automotive under-hood and powertrain applications per stress test requirements. |
Pinout & Package
The MPLAD36KP22A/TR uses the PLAD (Power Leadless Array Device) package: a low-profile, thermally enhanced surface-mount outline with a metal base acting as the cathode terminal and primary heat path. Dimensions are 10.3 × 8.4 × 3.2 mm (L × W × H); weight ≈ 1.7–2.0 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Metal Base (Bottom) | Cathode | Primary current return path and thermal interface; must be soldered to large copper pour or heatsink for RθJC = 1.0 °C/W performance. |
| Top Surface Pad | Anode | Signal-side connection; routed to protected line (e.g., 24 V rail input); minimal trace inductance critical for <100 ps response. |
Key Features
| Feature | Design Value |
|---|---|
| 36 kW Peak Pulse Power | Enables single-device protection against severe load dump and lightning-induced surges without cascaded stages. |
| Low RθJC = 1.0 °C/W | Allows direct thermal coupling to PCB copper or external heatsink, sustaining >100 pulses at 1 Hz without derating. |
| AEC-Q101 Qualification | Validates reliability for automotive 12 V/24 V systems including engine control units and ADAS power supplies. |
| RTCA DO-160G Compliance | Meets Section 22 multi-stroke lightning and Waveform 4/5A pin injection (Level 4/5) for avionics power inputs. |
| Moisture Sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing cost and risk of popcorning. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22A | Lower peak power (600 W), higher clamping voltage (35.5 V @ 17.1 A), SMB package with RθJA = 110 °C/W. | Only suitable for low-energy ESD/EFT; cannot meet DO-160G Level 5 or IEC 61000-4-5 Class 5. | Select SMBJ22A only for cost-sensitive consumer-grade 24 V interfaces where surge energy is limited to <100 A. |
| SMCJ22A | Higher peak power (1500 W), clamping voltage 35.5 V @ 42.5 A, SMC package with RθJC = 2.5 °C/W. | Supports IEC 61000-4-5 Class 3 (42 Ω), but insufficient for multi-stroke lightning or automotive load dump. | Choose SMCJ22A for industrial 24 V I/O where 1.5 kW surge capacity suffices and heatsinking is constrained. |
Compared with SMBJ22A and SMCJ22A, the MPLAD36KP22A/TR provides 24× and 24× higher peak power respectively, with 1/2.5× and 1/2.5× lower junction-to-case thermal resistance - making it the only option qualified for aerospace lightning and automotive load dump where multi-kiloampere, multi-stroke robustness is mandatory.

FAQ
What is the clamping voltage of MPLAD36KP22A/TR at its rated peak pulse current?
The MPLAD36KP22A/TR has a maximum clamping voltage (VC) of 36.4 V when subjected to its rated peak pulse current (IPP) of 990 A under the standard 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that downstream circuitry sees no more than 36.4 V during worst-case surge events, making MPLAD36KP22A/TR suitable for protecting 36 V-tolerant ICs in 24 V systems.
Is MPLAD36KP22A/TR RoHS-compliant and what does the "TR" suffix indicate?
Yes, MPLAD36KP22A/TR is RoHS-compliant (per e3 marking), and the "TR" suffix denotes tape-and-reel packaging per EIA-481-B standard - optimized for automated SMT placement. The device uses matte-tin plating on terminals and void-free UL94V-0 epoxy molding, fully compliant with lead-free reflow profiles up to 260 °C for 10 seconds. MPLAD36KP22A/TR is supplied in custom reel quantities per factory agreement.
How does the thermal performance of MPLAD36KP22A/TR compare to standard SMB/SMC TVS diodes?
MPLAD36KP22A/TR achieves RθJC = 1.0 °C/W due to its metal-base PLAD package, which directly conducts heat into the PCB copper or external heatsink. In contrast, SMBJ22A and SMCJ22A exhibit RθJC values of ~40 °C/W and ~2.5 °C/W respectively. This 2.5× lower thermal resistance allows MPLAD36KP22A/TR to sustain repeated 990 A surges without thermal runaway - a critical advantage absent in standard packages.
Can MPLAD36KP22A/TR be used for bidirectional surge protection?
No - MPLAD36KP22A/TR is unidirectional (indicated by the "A" suffix). For bidirectional operation, Microsemi offers the MPLAD36KP22CA variant (with "CA" suffix), which provides symmetrical clamping for AC-coupled or floating lines. Using MPLAD36KP22A/TR in bidirectional configurations risks forward conduction and failure; always match polarity suffix to system grounding and signal topology requirements.
Which industry standards does MPLAD36KP22A/TR explicitly meet according to its datasheet?
MPLAD36KP22A/TR is documented to meet RTCA DO-160G Section 22 (multi-stroke lightning), IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) with 42 Ω, 12 Ω, and 2 Ω source impedances across Classes 1–5. It is also AEC-Q101 qualified and rated for operation from –55 °C to +150 °C - confirming compliance for automotive, aerospace, and harsh-environment industrial use cases.
