Product details
Overview
MDA3KP24CAE3 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 protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD suppression per IEC61000-4-2, and EFT protection per IEC61000-4-4. It features a 24 V standoff voltage (VWM), 26.7–29.5 V breakdown range (V(BR)), and clamps to ≤38.9 V at 77.2 A peak pulse current (IPP).
For engineers reviewing the MDA3KP24CAE3 datasheet, MDA3KP24CAE3 pinout, MDA3KP24CAE3 application, or MDA3KP24CAE3 equivalent, this device serves as a RoHS-compliant, MIL-PRF-19500 upscreenable TVS for industrial power supplies, telecom interfaces, and automotive control modules requiring robust surge immunity with sub-5 ns response time and traceable lot-level reliability.
Technical Context
The MDA3KP24CAE3 employs an avalanche diode structure optimized for fast transient suppression, delivering <5 ns response time in bidirectional configuration. Its 3000 W peak pulse power rating (10/1000 µs waveform) is validated across temperature via derating curves and supported by full lot surge testing per specification.
Designed for surface-mount assembly with void-free UL94V-0 epoxy packaging and matte-tin terminations, the device maintains stable clamping performance under repeated transients while meeting IPC/JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | 600 W PPP rating, DO-214AA package, same VWM/V(BR)/VC specs but lower energy handling. | Suitable for consumer-grade ESD/EFT only; insufficient for IEC61000-4-5 Class 3+ lightning simulation. | Select when cost and board space constrain design, and surge threat level is limited to ±8 kV ESD or 1 kV EFT. |
| 1.5KE24CA | 3000 W PPP, axial leaded DO-15 package, identical electrical specs but not surface-mount compatible. | Requires through-hole assembly and manual rework; incompatible with automated SMT lines. | Choose only for legacy repair or prototyping where SMT footprint is unavailable and hand-soldering is acceptable. |

FAQ
What is the clamping voltage of MDA3KP24CAE3 at its rated peak pulse current?
The MDA3KP24CAE3 has a maximum clamping voltage (VC) of 38.9 V at its rated peak pulse current (IPP) of 77.2 A under 10/1000 µs waveform conditions. This value is measured per standard test methods defined in the datasheet and represents the upper limit of voltage seen by protected circuitry during worst-case surge events. The MDA3KP24CAE3 maintains this clamping performance across its full operating temperature range with appropriate derating applied above 25 °C.
Is MDA3KP24CAE3 suitable for bidirectional signal line protection?
Yes, MDA3KP24CAE3 is explicitly designed as a bidirectional TVS, indicated by the "C" suffix in its part number. Its symmetrical avalanche structure provides matched clamping in both polarities, making it ideal for protecting AC-coupled or differential interfaces such as RS-485, CAN, and Ethernet PHY lines. Unlike unidirectional variants, MDA3KP24CAE3 requires no orientation during placement and delivers consistent performance regardless of transient polarity.
Does MDA3KP24CAE3 meet RoHS requirements?
Yes, MDA3KP24CAE3 complies with RoHS Directive 2011/65/EU, as confirmed by the "e3" suffix in its marking. The device uses matte-tin plating on terminations and halogen-free, UL94V-0 compliant epoxy encapsulation. No lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE substances exceed allowable thresholds, supporting environmentally responsible manufacturing and end-of-life processing.
What is the standoff voltage rating of MDA3KP24CAE3 and how does it relate to system design?
The MDA3KP24CAE3 has a rated reverse standoff voltage (VWM) of 24 V, meaning it remains non-conductive up to this peak DC or RMS voltage under normal operation. System designers must ensure that maximum continuous operating voltage-including ripple, tolerance, and transients-does not exceed VWM to avoid premature conduction or accelerated aging. For a nominal 24 V system, this provides a safe margin against typical 10–20% overvoltage conditions while enabling effective clamping above 26.7 V.
Can MDA3KP24CAE3 be used in automotive applications requiring AEC-Q200 qualification?
MDA3KP24CAE3 is not AEC-Q200 qualified out of the box, but it supports optional MIL-PRF-19500 upscreening which includes extended temperature cycling, burn-in, and lot-level parametric screening-commonly accepted as equivalent or superior for many automotive Tier 1 suppliers. Customers requiring formal AEC-Q200 certification should consult Microchip's qualified product list or request specific upscreening documentation for MDA3KP24CAE3 prior to design-in.
