Product details
Overview
MAPLAD36KP100AE3 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, features a 100 V reverse standoff voltage (VWM), clamps to ≤162 V at 223 A peak impulse current (IPP), and operates across –55°C to +150°C junction temperature. It is qualified to AEC-Q101 and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MAPLAD36KP100AE3 datasheet, MAPLAD36KP100AE3 pinout, MAPLAD36KP100AE3 application, or MAPLAD36KP100AE3 equivalent, key selection criteria include its 100 V VWM rating, 162 V max clamping voltage at 223 A, low 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 source impedance (Class 1–5).
Technical Context
This TVS diode uses silicon avalanche technology to provide fast-response overvoltage clamping with sub-100 ps response time. Its metal-base package enables direct thermal coupling to PCB copper or heatsinks, supporting high-repetition-rate transients when mounted on FR4 with recommended pad layout.
It is characterized for operation under 0.05% duty factor impulse conditions and supports steady-state dissipation of 2.5 W at 25°C ambient or 71 W at 100°C case temperature. Standby leakage current is specified ≤10 μA at 100 V VWM, and breakdown occurs between 111 V and 123 V at 5 mA test current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - Maximum continuous operating voltage before clamping begins; matches 85–100 V DC bus or 70 V RMS AC systems. |
| V(BR) min/max | 111 V / 123 V @ 5 mA - Confirmed avalanche onset range; ensures reliable triggering above nominal system voltage. |
| VC @ IPP | ≤162 V @ 223 A - Clamping voltage under 10/1000 μs surge; limits downstream component stress to safe levels. |
| PPP | 36,000 W @ 10/1000 μs - Peak pulse power handling capacity; validated per Figure 1 and MIL-STD-883 methods. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; enables efficient heat transfer to external heatsink or copper plane. |
| ID @ VWM | ≤10 μA - Low standby leakage; minimizes power loss in always-on protection circuits. |
| Operating Temp | –55°C to +150°C - Full industrial/aerospace temperature range; qualified per AEC-Q101 stress testing. |
Pinout & Package
MAPLAD36KP100AE3 uses a surface-mount PLAD package with two terminals: anode and cathode. The cathode is the metal base (bottom side) of the device; polarity marking is present only on unidirectional versions. Package dimensions are 12.32 × 10.54 × 5.08 mm (L × W × H), with void-free UL94V-0 epoxy body and annealed matte-tin (e3) plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal for unidirectional conduction path | Connected to protected line; conducts during reverse-biased surge events when cathode is held at higher potential. |
| Cathode (Metal Base) | Reference/ground terminal; primary thermal interface | Mounted directly to PCB copper pour or heatsink; serves as both electrical return and primary heat dissipation path. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ100A | Lower PPP rating (400 W), smaller SMA package, 1.5x higher RθJA (75 °C/W), same 100 V VWM and unidirectional polarity. | Restricted to low-energy transients (e.g., ESD/EFT); unsuitable for DO-160 lightning or automotive load dump. | Select SMAJ100A only for cost-sensitive consumer electronics where surge energy remains below 100 J. |
| Vishay V130LS10 | Higher VWM (130 V), lower IPP (170 A), same PLAD footprint but non-RoHS (SnPb) termination; no AEC-Q101 or DO-160 documentation. | Applicable only in legacy industrial designs requiring 130 V standoff; lacks aerospace qualification and modern environmental compliance. | Choose V130LS10 only if existing PCB layout mandates identical mechanical fit and RoHS is not required. |
Compared with SMAJ100A and V130LS10, MAPLAD36KP100AE3 uniquely combines 36 kW surge capability, AEC-Q101 qualification, DO-160 compliance, and e3 RoHS termination in a single surface-mount device-making it irreplaceable for high-reliability transportation and aerospace surge protection.

FAQ
What is the maximum clamping voltage of MAPLAD36KP100AE3 under surge conditions?
The MAPLAD36KP100AE3 has a maximum clamping voltage (VC) of 162 V when subjected to its rated peak impulse current of 223 A under the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and is measured per Figure 3 in the RF01216 datasheet. The clamping performance ensures downstream circuitry remains within safe voltage margins during high-energy transients.
Is MAPLAD36KP100AE3 qualified for automotive applications?
Yes, MAPLAD36KP100AE3 is fully qualified to AEC-Q101 for automotive use. It undergoes high-temperature operating life (HTOL), temperature cycling (TC), unbiased highly accelerated stress test (UHAST), and ESD testing per the standard. Its 100 V VWM and 162 V clamping align with 12 V system load dump requirements, and its thermal design supports under-hood placement with proper PCB copper area.
Does MAPLAD36KP100AE3 meet RTCA DO-160 lightning protection requirements?
Yes, MAPLAD36KP100AE3 is explicitly validated for RTCA DO-160 Section 22 multi-stroke lightning testing. It achieves Level 4 and Level 5 pin injection protection per Waveforms 4 (6.4/69 μs) and 5A (40/120 μs), and supports full-system compliance when used with appropriate PCB layout and grounding per MicroNote 132. Its 36 kW rating exceeds typical DO-160 test energy thresholds.
What is the thermal resistance and how should MAPLAD36KP100AE3 be mounted for optimal cooling?
MAPLAD36KP100AE3 has a junction-to-case thermal resistance (RθJC) of 1.0 °C/W. For optimal cooling, mount the metal base (cathode) directly onto a minimum 25 mm² copper pour on inner or outer PCB layers, using the recommended pad layout from RF01216 Rev B. Avoid thermal vias beneath the base; instead, use solid copper planes connected to chassis ground or dedicated heatsinks for sustained high-duty-cycle operation.
What does the 'E3' suffix indicate in MAPLAD36KP100AE3?
The 'E3' suffix in MAPLAD36KP100AE3 denotes RoHS-compliant matte-tin plating per JEDEC J-STD-020B Level 1 moisture sensitivity-meaning no dry pack is required prior to assembly. This termination is solderable using standard SnPb or lead-free reflow profiles and ensures compatibility with modern manufacturing processes while maintaining the same electrical and thermal performance as non-RoHS variants.
