Product details
Overview
MDA3KP10CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, designed for high-reliability secondary lightning and ESD protection. It features a 10 V reverse standoff voltage (VWM), 11.1–12.3 V breakdown voltage (V(BR)), 17.0 V maximum clamping voltage at 176.4 A peak pulse current, and operates from –55 °C to +150 °C - deployed in telecom power interfaces and industrial I/O modules.
For engineers reviewing the MDA3KP10CAE3 datasheet, MDA3KP10CAE3 pinout, MDA3KP10CAE3 application, or MDA3KP10CAE3 equivalent, key selection criteria include bidirectional surge capability, IEC61000-4-2/4-4/4-5 compliance, 10/1000 µs waveform handling, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility for aerospace-grade deployments.
Technical Context
The MDA3KP10CAE3 is a silicon avalanche diode-based TVS array with symmetrical bidirectional clamping behavior, enabling protection of AC-coupled or differential signal lines without polarity concerns. Its sub-5 ns response time ensures suppression of ESD events per IEC61000-4-2 and fast transients per IEC61000-4-4 before downstream circuitry is stressed.
It delivers 3000 W peak pulse power at 10/1000 µs under 0.05% duty cycle, with clamping performance validated across temperature via derating curves (Figure 3). Polarity is defined by odd-numbered pins as cathodes, and the device is fully surge-tested per production lot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Reverse Standoff) | 10 V - Maximum continuous operating voltage before clamping initiates; matches nominal 12 V rail systems with margin. |
| V(BR) Min/Max | 11.1–12.3 V @ I(BR) - Confirmed avalanche onset range; ensures reliable triggering above system peak voltage. |
| VC @ IPP | 17.0 V @ 176.4 A - Clamping voltage during worst-case 10/1000 µs surge; limits stress on protected ICs to safe levels. |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy transients common in industrial Ethernet and PoE ports. |
| TJ/TSTG Range | –55 °C to +150 °C - Supports operation in extended-temperature environments including automotive engine bays and outdoor base stations. |
| RoHS Status | e3 suffix - Matte-tin plating compliant with EU RoHS Directive 2011/65/EU; no lead or hazardous substances. |
| ID @ VWM | 5 µA max - Ultra-low leakage preserves signal integrity and battery life in always-on monitoring circuits. |
Pinout & Package
MDA3KP10CAE3 uses a 2-pin DO-214AB (SMC) surface-mount package with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity marked by a dot indicating Pin 1 (cathode). Weight ≈5 g; moisture sensitivity level (MSL) = 1 - no dry pack required per J-STD-020B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Bidirectional) | Common reference terminal for symmetrical clamping; connects to protected line or ground depending on layout. |
| Pin 2 | Anode (Bidirectional) | Second terminal completing the bidirectional avalanche path; enables equal clamping in both voltage polarities. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or ungrounded interfaces without polarity constraints. |
| 3000 W peak pulse rating | Withstands high-energy surges from inductive switching or lightning-induced coupling in industrial control cabinets. |
| MIL-PRF-19500 upscreening option | Supports high-reliability qualification for defense/aerospace programs requiring lot traceability and 3σ ID screening. |
| Sub-5 ns response time | Clamps ESD events faster than most interface ICs can respond, preventing latch-up or gate oxide damage. |
| Level 1 MSL rating | Eliminates pre-bake requirements during SMT assembly, reducing manufacturing cost and process complexity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | 600 W PPP rating; same VWM (10 V) and bidirectional configuration but lower surge capacity. | Suitable for consumer-grade USB or low-energy sensor nodes; insufficient for IEC61000-4-5 Class 3+. | Select MDA3KP10CAE3 when 3000 W surge immunity and MIL-qualified reliability are required. |
| 1.5KE10CA | Through-hole TO-218 package; identical electrical specs but incompatible with SMT production and higher thermal resistance. | Used in legacy power supply designs where board space and assembly method permit through-hole mounting. | Choose MDA3KP10CAE3 for automated SMT lines, reduced footprint, and improved thermal cycling performance. |
Compared with SMBJ10CA and 1.5KE10CA, MDA3KP10CAE3 uniquely combines surface-mount scalability, 3000 W surge headroom, and MIL-PRF-19500 upscreening readiness - making it optimal for new industrial and aerospace designs demanding long-term supply stability and high-energy resilience.

FAQ
What does the 'C' in MDA3KP10CAE3 indicate?
The 'C' suffix in MDA3KP10CAE3 denotes bidirectional polarity - meaning the device provides symmetrical clamping for both positive and negative transients. This allows single-device protection of AC-coupled lines like RS-485 or telephone interfaces without external polarity considerations. The MDA3KP10CAE3 achieves this using back-to-back avalanche diode structure, verified in its electrical characteristics table and confirmed by the "Bidirectional" designation in the nomenclature guide on page 2 of RF01243 Rev B.
Is MDA3KP10CAE3 compatible with lead-free reflow processes?
Yes, MDA3KP10CAE3 supports lead-free reflow soldering with a peak temperature of 260 °C for 10 seconds, as specified in the Maximum Ratings table (Page 2). Its matte-tin (e3) plating meets J-STD-020B Level 1 moisture sensitivity, eliminating pre-bake requirements. This makes MDA3KP10CAE3 suitable for standard Pb-free SMT lines without process modification or reliability risk.
How does MDA3KP10CAE3 perform under elevated temperature conditions?
MDA3KP10CAE3 maintains functional clamping performance up to +150 °C junction temperature, with derating applied to peak pulse power per Figure 3 in RF01243 Rev B. At 100 °C, its PPP drops to ~70% of the 25 °C rating (≈2100 W), and standby leakage remains ≤5 µA. This thermal stability enables use in engine control units and outdoor telecom enclosures where ambient temperatures exceed 85 °C.
Can MDA3KP10CAE3 be used for IEC61000-4-5 Class 4 lightning protection?
No - MDA3KP10CAE3 is rated for IEC61000-4-5 Class 1–3 with 12 Ω source impedance and Class 1–4 with 42 Ω source impedance, as stated in the Applications/Benefits section (Page 1). For Class 4 with 2 Ω source, only MDA3KP6.0A–MDA3KP9.0A variants are approved. Using MDA3KP10CAE3 in a 2 Ω Class 4 test setup exceeds its validated energy handling and may result in non-compliance.
What is the significance of the 'E3' suffix in MDA3KP10CAE3?
The 'E3' suffix in MDA3KP10CAE3 indicates RoHS-compliant matte-tin terminal plating per EU Directive 2011/65/EU, replacing traditional tin-lead finishes. This ensures environmental compliance without sacrificing solderability or corrosion resistance. The 'e3' marking is explicitly defined in the nomenclature diagram on Page 2 of RF01243 Rev B and confirms full conformance to JEDEC J-STD-609A Class 3 marking standards.
