Product details
Overview
MAPLAD36KP130AE3 from Microsemi is a unidirectional 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, clamps transients to ≤209 V at 173 A peak impulse current, and features a 130 V reverse standoff voltage (VWM), 144–159 V breakdown voltage (V(BR)), and 1.0 °C/W junction-to-case thermal resistance.
For engineers reviewing the MAPLAD36KP130AE3 datasheet, MAPLAD36KP130AE3 pinout, MAPLAD36KP130AE3 application, or MAPLAD36KP130AE3 equivalent, key selection criteria include RTCA DO-160F Waveform 4/5A compliance, IEC 61000-4-5 Class 4 secondary lightning protection with 2 Ω source impedance, and suitability for high-reliability avionics power rail protection where low thermal resistance and RoHS-compliant matte-tin plating are required.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuitry, activating above its 130 V standoff threshold to divert surge energy away from downstream components. Its void-free UL94V-0 epoxy package and metal-base cathode construction enable efficient heat dissipation, supporting sustained multi-stroke lightning events per RTCA DO-160 Section 22.
It meets AEC-Q101 stress testing requirements and supports MIL-PRF-19500 upscreening options. Electrical behavior is defined by precise V(BR) tolerance (±5%), low standby current (≤10 μA @ VWM), and fast response time (<100 ps for unidirectional clamping).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 36,000 W @ 10/1000 μs - enables single-device protection against severe lightning-induced surges without cascaded staging |
| Reverse Standoff Voltage (VWM) | 130 V - sets maximum continuous operating voltage before clamping activation; matches 115 VAC-derived DC rails |
| Breakdown Voltage (V(BR)) | 144–159 V @ 5 mA - defines guaranteed conduction onset range; ensures margin above VWM for noise immunity |
| Clamping Voltage (VC) | 209 V @ 173 A - limits voltage seen by protected ICs during worst-case surge; critical for 200 V-rated bus components |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - allows direct mounting to heatsink or copper pour for thermal management under repetitive surge duty |
| Standby Current (ID) | ≤10 μA @ 130 V - minimizes leakage impact on low-power avionics monitoring circuits |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - eliminates dry-pack requirement and bake-out prior to reflow soldering |
Pinout & Package
The MAPLAD36KP130AE3 uses a surface-mount PLAD package with metal base cathode terminal and top-side anode pad. The cathode is the exposed metal underside of the device body; polarity marking is present only on unidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (top-side pad) | Surge current entry point | Connected to protected line; must be routed with low-inductance trace to minimize overshoot during fast transients |
| Cathode (metal base) | Surge current return path & thermal interface | Must be soldered directly to large copper area or heatsink; serves dual role as electrical terminal and primary thermal conduction path |
Key Features
| Feature | Design Value |
|---|---|
| RoHS-compliant matte-tin plating | Enables lead-free reflow compatibility while maintaining solderability per MIL-STD-750 Method 2026 |
| UL94V-0 void-free epoxy body | Provides flame-retardant mechanical integrity and moisture resistance for extended field life in humid environments |
| RTCA DO-160F Waveform 4/5A compliance | Validated for pin-injection surge immunity up to Level 5 (Waveform 4: 130 V VWM variant qualifies to Level 4) |
| AEC-Q101 qualification | Confirms robustness against temperature cycling, humidity, and mechanical shock for automotive-grade deployment |
| 3σ lot norm screening on ID | Ensures consistent low-leakage performance across production lots-critical for battery-backed avionics monitoring |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | 600 W PPP rating, SMC package, 1.5x higher RθJA (1.5 °C/W), no DO-160F validation | Limited to industrial-grade single-stroke surges; unsuitable for aviation multi-stroke certification | Select when cost sensitivity outweighs aerospace qualification and thermal performance requirements |
| SMCJ130A | 1500 W PPP rating, same SMC package, 1.5 °C/W RθJA, AEC-Q101 qualified but not DO-160F tested | Acceptable for automotive load dump but lacks RTCA waveform validation and 36 kW energy handling | Choose for ground vehicle ECUs where full DO-160F compliance is not mandated |
Compared with SMBJ130A and SMCJ130A, the MAPLAD36KP130AE3 provides 24× and 24× higher peak pulse power respectively, validated RTCA DO-160F Waveform 4/5A immunity, and superior thermal management via 1.0 °C/W RθJC-making it the only option for certified avionics surge protection at this voltage class.

FAQ
What is the clamping voltage of MAPLAD36KP130AE3 at its rated peak pulse current?
The MAPLAD36KP130AE3 has a maximum clamping voltage (VC) of 209 V at 173 A peak pulse current (IPP) under 10/1000 μs waveform conditions. This value is measured per standard test methods and guarantees that protected circuitry will not experience voltages exceeding 209 V during worst-case surge events. The clamping performance is integral to the device's qualification for RTCA DO-160F Waveform 4 Level 4 and IEC 61000-4-5 Class 4 applications. MAPLAD36KP130AE3 maintains this specification across its full operating temperature range.
Is MAPLAD36KP130AE3 compliant with RoHS and halogen-free standards?
Yes, MAPLAD36KP130AE3 carries the "e3" suffix, indicating full RoHS compliance per EU Directive 2011/65/EU with annealed matte-tin plating and no lead, cadmium, mercury, hexavalent chromium, PBB, or PBDE. The device also meets IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1, eliminating dry-pack requirements. MAPLAD36KP130AE3's void-free UL94V-0 epoxy body contains no halogenated flame retardants, satisfying stringent environmental and safety mandates for aerospace and rail deployments.
How does the thermal design of MAPLAD36KP130AE3 differ from standard SMC/SMB TVS diodes?
MAPLAD36KP130AE3 features a dedicated metal-base cathode that serves as both electrical terminal and primary thermal conduction path, achieving 1.0 °C/W junction-to-case thermal resistance-significantly lower than typical SMC (1.5 °C/W) or SMB (3.0 °C/W) packages. This enables direct mounting to heatsinks or large copper pours, critical for managing cumulative heating during multi-stroke lightning events. MAPLAD36KP130AE3's thermal architecture is validated for RTCA DO-160 Section 22 testing, unlike conventional surface-mount TVS diodes which lack such thermal derating data.
Does MAPLAD36KP130AE3 meet RTCA DO-160F lightning test requirements?
Yes, MAPLAD36KP130AE3 is explicitly validated for RTCA DO-160F Section 22 lightning-induced transient susceptibility. It achieves Level 4 for Waveform 4 (6.4/69 μs) and Level 4 for Waveform 5A (40/120 μs) at its 130 V standoff rating. These certifications are documented in Microsemi's RF01216 Rev B datasheet and supported by test reports available upon request. MAPLAD36KP130AE3 is one of few surface-mount TVS devices qualified for multi-stroke lightning testing, making it suitable for primary and secondary protection in certified avionics equipment.
What is the polarity configuration and pin identification method for MAPLAD36KP130AE3?
MAPLAD36KP130AE3 is a unidirectional TVS diode with cathode on the metal base (underside) and anode on the top-side solder pad. Polarity is marked on the device body per standard convention, and the cathode connection must be tied to the system ground or lowest-potential reference plane. This configuration ensures proper clamping directionality for positive-going transients on positive rails. The absence of a "CA" suffix confirms unidirectional construction, distinguishing it from bidirectional variants like MAPLAD36KP130CA. MAPLAD36KP130AE3's polarity definition is critical for correct placement in DO-160F-compliant layouts.
