Product details
Overview
MDA3KP7.0CAE3 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 7.0 V reverse standoff voltage (VWM), 7.78–8.6 V breakdown voltage (V(BR)), 12.0 V maximum clamping voltage at 250 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MDA3KP7.0CAE3 datasheet, MDA3KP7.0CAE3 pinout, MDA3KP7.0CAE3 application, or MDA3KP7.0CAE3 equivalent, key selection criteria include bidirectional polarity, IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω/2 Ω source impedances, 100 ps response time, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MDA3KP7.0CAE3 implements a symmetrical bidirectional avalanche diode structure optimized for fast transient suppression in harsh environments. Its sub-100 ps response enables effective mitigation of ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5) without degradation under repeated 10/1000 µs impulses.
It delivers 3000 W peak pulse power at 25 °C with full derating above 25 °C per Figure 3, supports 250 A IPP at VC = 12.0 V, and maintains <2 µA standby current at VWM = 7.0 V - enabling low-leakage protection in always-on circuits such as industrial I/O and telecom line interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - Maximum continuous operating voltage before clamping begins; matches 5 V or 3.3 V rail systems with margin. |
| V(BR) min/max | 7.78–8.6 V - Confirmed avalanche onset range at 10 mA; ensures predictable turn-on without premature conduction. |
| VC @ IPP | 12.0 V at 250 A - Clamping voltage during worst-case 10/1000 µs surge; limits downstream voltage stress to safe levels. |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy transients typical of lightning-induced surges in outdoor equipment. |
| Response time | <100 ps - Enables protection against nanosecond-scale ESD events before sensitive ICs are damaged. |
| Operating temp | –55 °C to +150 °C - Supports deployment in automotive engine compartments and industrial motor drives. |
| RoHS | e3 - Matte-tin termination compliant with EU RoHS Directive 2011/65/EU; no lead or hazardous substances. |
Pinout & Package
MDA3KP7.0CAE3 uses a DO-214AB (SMC) surface-mount package with two terminals: Pin 1 (cathode) and Pin 2 (anode). Polarity is bidirectional - both terminals function symmetrically as cathode/anode depending on transient polarity. Package dimensions: 21.03 × 6.86 × 8.64 mm (L × W × H), void-free UL94V-0 epoxy body, tin-lead or matte-tin plating per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (bidirectional) | Serves as cathode during positive transients; anode during negative transients - enables symmetrical clamping. |
| Pin 2 | Anode (bidirectional) | Serves as anode during positive transients; cathode during negative transients - completes bidirectional path. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection of AC lines or differential buses without polarity constraints. |
| 3000 W peak pulse rating | Withstands high-energy lightning surges per IEC61000-4-5 with 42 Ω, 12 Ω, and 2 Ω source impedances. |

| Level 1 moisture sensitivity | Eliminates dry-pack requirement per IPC/JEDEC J-STD-020B - simplifies handling and reflow assembly. |
| Sub-100 ps response | Prevents latch-up or gate oxide damage in CMOS interfaces exposed to fast-rising ESD events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package (smaller footprint) | Limited to lower-energy transients; not rated for IEC61000-4-5 Class 4 with 2 Ω source impedance | Select when board space is constrained and surge energy remains below 600 W. |
| 1.5KE7.0CA | 1500 W PPP, axial-leaded DO-15 package, higher thermal resistance, no MIL-PRF-19500 screening option | Requires through-hole assembly; unsuitable for automated SMT production or high-reliability aerospace programs | Select only for cost-sensitive, non-SMT legacy designs where 1500 W protection suffices. |
Compared with SMBJ7.0CA and 1.5KE7.0CA, the MDA3KP7.0CAE3 provides double the pulse power rating of the SMBJ series and triple that of the 1.5KE series, while supporting surface-mount automation, MIL-PRF-19500 upscreening, and full IEC61000-4-5 Class 4 compliance - making it optimal for mission-critical industrial and telecom infrastructure.

FAQ
What does the 'C' suffix in MDA3KP7.0CAE3 indicate?
The 'C' suffix in MDA3KP7.0CAE3 denotes bidirectional polarity - meaning the device functions identically for both positive and negative transients across its two terminals. This eliminates the need for polarity-aware layout and enables protection of AC-coupled or differential signal paths. The MDA3KP7.0CAE3 achieves symmetrical clamping with V(BR) = 7.78–8.6 V in either direction and VC = 12.0 V at 250 A, making it ideal for telecom and industrial bus protection where signal polarity varies.
Is MDA3KP7.0CAE3 suitable for IEC61000-4-5 Class 4 testing?
Yes, MDA3KP7.0CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 12 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. It sustains the required 4 kV open-circuit test waveform without failure, delivering 3000 W peak pulse power at 10/1000 µs. Its 12.0 V clamping voltage ensures downstream circuitry remains within safe operating limits during the surge event.
What is the maximum clamping voltage of MDA3KP7.0CAE3 and at what current is it specified?
The maximum clamping voltage (VC) of MDA3KP7.0CAE3 is 12.0 V, measured at a peak pulse current (IPP) of 250 A under 10/1000 µs waveform conditions. This value is guaranteed across the full operating temperature range and represents the upper limit of voltage seen by protected circuitry during worst-case surge events. It is significantly lower than competing 7 V-rated TVS devices, reducing stress on downstream ICs such as RS-485 transceivers and microcontroller I/O pins.
Does MDA3KP7.0CAE3 require dry packing or special handling before reflow soldering?
No, MDA3KP7.0CAE3 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions without dry packing or baking prior to reflow. Its void-free UL94V-0 epoxy body and matte-tin termination ensure robust thermal performance during standard Pb-free or SnPb reflow profiles, including peak temperatures up to 260 °C for 10 seconds.
Can MDA3KP7.0CAE3 be used in automotive applications requiring AEC-Q200 qualification?
MDA3KP7.0CAE3 is not AEC-Q200 qualified; however, it meets or exceeds several AEC-Q200 stress test requirements - including operating temperature (–55 °C to +150 °C), surge robustness, and solderability - and supports optional MIL-PRF-19500 upscreening for high-reliability automotive subsystems like body control modules. For production automotive use, validation per AEC-Q200 must be performed by the end customer, but the MDA3KP7.0CAE3's design basis and screening options make it a strong candidate for such qualification efforts.
