Product details
Overview
MDA3KP8.0CAE3 from Microsemi is a bidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in industrial power interfaces. It features a 8.0 V reverse standoff voltage (VWM), 8.89–9.83 V breakdown voltage (V(BR)), 13.6 V maximum clamping voltage (VC) at 220.6 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MDA3KP8.0CAE3 datasheet, MDA3KP8.0CAE3 pinout, MDA3KP8.0CAE3 application, or MDA3KP8.0CAE3 equivalent, key selection criteria include bidirectional polarity, IEC61000-4-2/4-4/4-5 compliance, 10/1000 µs surge rating, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MDA3KP8.0CAE3 implements a silicon avalanche diode structure optimized for sub-nanosecond response (<5 ns) under bidirectional transients. Its clamping behavior is characterized at 220.6 A IPP with VC ≤13.6 V, enabling robust protection of 3.3 V and 5 V logic rails against induced surges and EFT bursts.
It supports secondary lightning protection per IEC61000-4-5 at Class 1–4 with 42 Ω source impedance and Class 4 with 12 Ω source impedance. Standby leakage ID is ≤50 µA at VWM, ensuring minimal power loss in always-on monitoring circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous operating voltage before conduction begins; matches nominal 5 V or 3.3 V bus systems with safety margin. |
| V(BR) min–max | 8.89–9.83 V - Confirmed avalanche onset range at 1 mA; ensures predictable turn-on without premature triggering. |
| VC @ IPP | 13.6 V - Clamped voltage during 220.6 A 10/1000 µs surge; protects downstream ICs rated for ≤15 V absolute max. |
| PPP | 3000 W - Peak pulse power handling at 10/1000 µs waveform; meets IEC61000-4-5 Level 4 requirements. |
| ID @ VWM | ≤50 µA - Low standby leakage at rated standoff; avoids signal integrity degradation in high-impedance sensor interfaces. |
| TJ/TSTG | –55 to +150 °C - Extended thermal range enables deployment in automotive engine bays and industrial motor drives. |
| RoHS | e3 - Matte-tin termination compliant with EU RoHS Directive 2011/65/EU; no lead or hazardous substance exemptions. |
Pinout & Package
MDA3KP8.0CAE3 uses a 3-pin SMC (DO-214AB) surface-mount package with void-free UL94V-0 epoxy body and tin-lead or matte-tin plating. Pin 1 is cathode; odd-numbered pins are cathodes per TVS element. Polarity marking is indicated by a dot on top of the package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (TVS1) | Common cathode connection for first bidirectional TVS element; ties to protected line or ground reference. |
| Pin 2 | Anode (TVS1) / Cathode (TVS2) | Center tap shared between two TVS elements; enables differential or common-mode protection configurations. |
| Pin 3 | Anode (TVS2) | Second cathode-anode pair anode terminal; completes bidirectional path across protected nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA | Lower PPP (600 W), same VWM and bidirectional polarity; SMC package identical but lower surge rating. | Suitable only for IEC61000-4-5 Class 2 (2 kV) or ESD-only use; not rated for Class 4 lightning. | Select when cost sensitivity outweighs surge margin and design does not require 3000 W capability. |
| SMCJ8.0CA | Same 3000 W PPP and VWM, but higher VC (13.5 V vs. 13.6 V); identical SMC package and RoHS e3 marking. | Valid drop-in replacement with identical footprint, thermal profile, and reliability screening options. | Prefer when sourcing flexibility is needed and manufacturer cross-qualification is established. |
Compared with SMBJ8.0CA, MDA3KP8.0CAE3 delivers 5× higher surge energy handling for mission-critical infrastructure; versus SMCJ8.0CA, it offers equivalent surge performance with documented MIL-PRF-19500 upscreening path and tighter V(BR) tolerance (±5% vs. ±10%).

FAQ
What is the clamping voltage of MDA3KP8.0CAE3 at its rated peak pulse current?
The MDA3KP8.0CAE3 has a maximum clamping voltage (VC) of 13.6 V at its rated peak pulse current (IPP) of 220.6 A under 10/1000 µs waveform conditions. This value is guaranteed per Microsemi's RF01243 Rev B datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MDA3KP8.0CAE3 maintains this clamping performance across its full operating temperature range.
Is MDA3KP8.0CAE3 suitable for IEC61000-4-5 Class 4 lightning protection?
Yes, MDA3KP8.0CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, as confirmed in the Applications/Benefits section of RF01243 Rev B. It also supports Class 4 with 12 Ω source impedance, making it appropriate for telecom and industrial power entry applications where high-energy coupled surges are expected. The MDA3KP8.0CAE3 achieves this with its 3000 W peak pulse power rating and verified clamping behavior.
What does the 'C' suffix in MDA3KP8.0CAE3 indicate?
The 'C' suffix in MDA3KP8.0CAE3 denotes bidirectional polarity, meaning the device provides symmetrical clamping for both positive- and negative-going transients across its terminals. This distinguishes it from unidirectional variants like MDA3KP8.0AE3 and enables use in AC-coupled lines, differential buses, or any application where voltage reversals must be suppressed without external polarity management. The MDA3KP8.0CAE3 implements this via dual back-to-back avalanche diode configuration.
Does MDA3KP8.0CAE3 require dry packing before reflow soldering?
No, MDA3KP8.0CAE3 is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life and does not require dry packing or baking prior to reflow soldering. This eliminates moisture-related popcorning risk and simplifies manufacturing logistics. The MDA3KP8.0CAE3 achieves this through void-free thermosetting epoxy encapsulation and controlled internal humidity levels, as verified in the Mechanical and Packaging section of RF01243 Rev B.
Can MDA3KP8.0CAE3 be used in automotive under-hood applications?
Yes, MDA3KP8.0CAE3 supports junction temperatures from –55 °C to +150 °C and is qualified for high-reliability operation in demanding environments. Its thermal stability, MIL-PRF-19500 upscreening eligibility, and robust 3000 W surge rating make it suitable for automotive body control modules, engine control unit power inputs, and other under-hood locations where thermal cycling and transient exposure are severe. The MDA3KP8.0CAE3 has been validated for such use in Microsemi's application guidance.
