Product details
Overview
MPLAD36KP58CAE3 from Microsemi is a bidirectional 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, clamps at ≤93.6 V under 385 A peak impulse current, and features a 58 V reverse standoff voltage (VWM), 64.4–71.2 V breakdown voltage (V(BR)), and 1.0 °C/W junction-to-case thermal resistance.
For engineers reviewing the MPLAD36KP58CAE3 datasheet, MPLAD36KP58CAE3 pinout, MPLAD36KP58CAE3 application, or MPLAD36KP58CAE3 equivalent, key selection criteria include its DO-160F Waveform 4 Level 4/5 pin-injection capability, IEC 61000-4-5 Class 4 secondary lightning protection (up to 280 V with 12 Ω source), and RoHS-compliant e3 matte-tin terminations on a low-profile thermoset epoxy package.
Technical Context
This device operates as a silicon avalanche diode-based TVS, leveraging controlled avalanche breakdown to clamp transients within nanoseconds. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal/power lines, and its metal-base cathode configuration provides low-inductance, high-current path integrity during multi-stroke events.
Designed for compliance with RTCA DO-160 Section 22 (lightning-induced transients) and IEC 61000-4-2/4/5, it supports multi-pulse survivability at ≤0.05% duty factor and maintains stable clamping performance across −55°C to +150°C junction temperature range with <100 ps response time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous operating voltage before conduction begins; sets minimum system voltage margin for reliable standby operation. |
| V(BR) min/max | 64.4–71.2 V - Breakdown occurs within this band at 5 mA; ensures predictable turn-on threshold across production lots. |
| VC @ IPP | 93.6 V max at 385 A - Clamping voltage under 10/1000 μs surge; defines worst-case overvoltage seen by protected circuitry. |
| PPP | 36,000 W - Peak pulse power handling at 10/1000 μs; enables single-device protection against severe lightning or load-dump events. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; allows direct heatsink mounting for sustained multi-pulse operation without derating. |
| ID @ VWM | 10 μA max - Standby leakage current at rated standoff; minimizes quiescent power loss in battery-backed or low-power systems. |
| Package | PLAD - Surface-mount void-free UL94V-0 epoxy body with metal base cathode; optimized for mechanical robustness and thermal dissipation on FR4 PCBs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | 600 W PPP rating, SMC package, 1.5x higher RθJA (30 °C/W), lower IPP (100 A). | Limited to single-stroke, low-duty-cycle consumer-grade protection; not qualified for DO-160 or AEC-Q101. | Select when cost sensitivity outweighs multi-stroke reliability and aerospace qualification requirements. |
| SMCJ58CA | 1500 W PPP, SMC package, RθJC ≈ 2.5 °C/W, IPP = 220 A, no DO-160 validation. | Suitable for industrial motor drives but lacks RTCA/DO-160F Waveform 4 certification and 36 kW pulse capability. | Choose for space-constrained designs needing >600 W but unable to accommodate PLAD footprint or qualification needs. |
Compared with SMBJ58CA and SMCJ58CA, the MPLAD36KP58CAE3 delivers 24× and 24× higher peak pulse power respectively, certified DO-160F compliance, and 2.5× lower thermal resistance - making it the only option for high-reliability, multi-stroke aerospace and heavy-duty automotive applications.

FAQ
What is the maximum clamping voltage of the MPLAD36KP58CAE3 under standard test conditions?
The MPLAD36KP58CAE3 has a maximum clamping voltage (VC) of 93.6 V when subjected to its rated peak pulse current (IPP) of 385 A under the 10/1000 μs waveform. This value is measured at 25°C and represents the worst-case overvoltage imposed on protected circuitry during a full-power surge event. The clamping performance remains stable across the full −55°C to +150°C operating junction temperature range.
Does the MPLAD36KP58CAE3 meet AEC-Q101 qualification requirements?
Yes, the MPLAD36KP58CAE3 is tested in accordance with AEC-Q101 requirements for discrete semiconductors, as confirmed in the RF01216 datasheet. This qualification validates its suitability for automotive electronic control units, including engine management, ADAS, and body electronics, where reliability under thermal cycling, humidity, and mechanical shock is critical. The device also supports optional MIL-PRF-19500 upscreening for extended reliability tiers.
How does the PLAD package of the MPLAD36KP58CAE3 improve thermal performance compared to standard SMC or SMB packages?
The PLAD package of the MPLAD36KP58CAE3 achieves a junction-to-case thermal resistance (RθJC) of just 1.0 °C/W - over 2× lower than typical SMC packages (~2.5 °C/W) and 3× lower than SMB packages (~3.0 °C/W). This is enabled by its exposed metal base cathode, which serves as a direct thermal path to the PCB copper pour or external heatsink, allowing sustained multi-pulse operation without thermal derating in high-ambient environments.
Can the MPLAD36KP58CAE3 be used for bidirectional signal line protection such as RS-485 or CAN bus?
Yes, the MPLAD36KP58CAE3 is explicitly designed for bidirectional operation (denoted by the "CA" suffix) and is suitable for protecting differential signal lines like RS-485 and CAN bus. Its symmetrical clamping characteristics ensure equal protection for both positive and negative transients, and its low capacitance (<100 pF typical) avoids signal integrity degradation at standard industrial data rates up to 1 Mbps. Layout requires balanced placement across the differential pair.
What is the significance of the "e3" suffix in MPLAD36KP58CAE3?
The "e3" suffix in MPLAD36KP58CAE3 indicates RoHS-compliant matte-tin plating on the terminations, fully compliant with Directive 2011/65/EU. This finish ensures compatibility with lead-free reflow soldering processes (up to 260°C for 10 seconds), meets MIL-STD-750 Method 2026 solderability requirements, and eliminates lead contamination risks in environmentally sensitive applications such as aerospace and medical electronics.
