Product details
Overview
MDA3KP7.0AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 7.0 V standoff voltage (VWM), 7.78–8.6 V breakdown voltage (V(BR)), and 12.0 V clamping voltage (VC) at 250 A peak pulse current. It delivers sub-100 ps response time, operates from –55 °C to +150 °C, and is RoHS-compliant per JEDEC J-STD-020B Level 1 moisture sensitivity. It protects power rails in industrial motor drives against IEC61000-4-5 secondary lightning surges.
For engineers reviewing the MDA3KP7.0AE3 datasheet, MDA3KP7.0AE3 pinout, MDA3KP7.0AE3 application, or MDA3KP7.0AE3 equivalent, key selection criteria include verified 7.0 V VWM tolerance, 12.0 V VC at 250 A, unidirectional polarity, 3000 W 10/1000 µs surge rating, and MIL-PRF-19500 upscreening eligibility for high-reliability deployments.
Technical Context
This TVS array uses silicon avalanche diode technology optimized for fast clamping of high-energy transients. Its unidirectional construction enables asymmetric protection on DC power lines, with cathode-defined polarity per odd-numbered pins and a 10/1000 µs waveform-rated 3000 W peak pulse power capability.
It meets IEC61000-4-2 ESD (±30 kV contact), IEC61000-4-4 EFT (40 A), and IEC61000-4-5 surge (Class 1–4, 42 Ω source) requirements. Standby leakage is ≤200 µA at 7.0 V, and forward clamping is 4.0 V at 500 A, supporting robust overvoltage suppression without latch-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 7.78–8.6 V @ 10 mA - Confirmed avalanche onset range for reliable turn-on threshold control |
| VC @ IPP | 12.0 V @ 250 A - Clamped voltage during full-rated 10/1000 µs surge, limiting downstream stress |
| PPP | 3000 W @ 10/1000 µs - Sustained energy absorption capacity for lightning-induced transients |

| Response time | <100 ps - Near-instantaneous triggering prevents voltage overshoot before protection engages |
Pinout & Package
MDA3KP7.0AE3 uses a 3-pin TO-277A (SMB) surface-mount package with void-free UL94V-0 epoxy body, tin-lead or matte-tin terminations, and polarity defined by dot-marked Pin 1 (cathode). Weight ≈5 g; dimensions: 21.03–22.05 mm × 6.86–7.87 mm × 8.64–9.65 mm (L×W×H).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A | 600 W PPP rating, same VWM (7.0 V), but lower VC (12.5 V @ 43.3 A) | Not suitable for Class 4 IEC61000-4-5; limited to lower-energy ESD/EFT-only zones | Select only when peak surge current remains below 45 A and PCB space constraints prohibit larger packages |
| SMCJ7.0A | 1500 W PPP rating, same VWM (7.0 V), VC = 12.0 V @ 125 A | Insufficient for 3000 W surge events; requires parallel devices for equivalent energy handling | Choose if legacy layout uses SMC package and surge duty cycle is low (<0.01%) |
Compared with SMAJ7.0A and SMCJ7.0A, MDA3KP7.0AE3 provides double the surge energy margin of SMCJ7.0A and five times that of SMAJ7.0A-enabling single-device Class 4 lightning protection without layout redesign or paralleling complexity.

FAQ
What is the maximum clamping voltage of MDA3KP7.0AE3 at its rated peak pulse current?
The MDA3KP7.0AE3 has a maximum clamping voltage (VC) of 12.0 V at 250 A peak pulse current under 10/1000 µs waveform conditions. This value is measured per Figure 2 in the official datasheet and defines the upper voltage limit imposed on protected circuitry during full-rated surge events. The MDA3KP7.0AE3 maintains this clamping performance across its full operating temperature range of –55 °C to +150 °C.
Is MDA3KP7.0AE3 suitable for bidirectional signal line protection?
No, MDA3KP7.0AE3 is a unidirectional TVS device, indicated by the absence of "C" in its part number suffix. It is designed exclusively for DC power rail protection where polarity is fixed. For bidirectional AC or data-line applications, Microsemi's MDA3KP7.0CE3 (with "C" suffix) must be used instead. The MDA3KP7.0AE3 will not conduct symmetrically and may fail catastrophically if reverse-biased beyond its VWM rating.
Does MDA3KP7.0AE3 require special handling due to moisture sensitivity?
No, MDA3KP7.0AE3 is rated IPC/JEDEC J-STD-020B Level 1, meaning it has no moisture sensitivity limitations and does not require dry packing or baking before reflow soldering. Its void-free thermosetting epoxy body and matte-tin plating ensure robust manufacturability in standard SMT processes. This eliminates process overhead associated with higher MSL levels and supports direct placement into high-volume production lines using the MDA3KP7.0AE3.
Can MDA3KP7.0AE3 be used in automotive under-hood applications?
Yes, MDA3KP7.0AE3 is qualified for operation from –55 °C to +150 °C junction temperature and meets IEC61000-4-2 (±30 kV contact ESD) and IEC61000-4-5 (Class 4, 42 Ω source) requirements-key criteria for automotive body control modules and engine control units. Its MIL-PRF-19500 upscreening option further validates suitability for under-hood deployment where thermal cycling and long-term reliability are critical for the MDA3KP7.0AE3.
What is the significance of the "e3" suffix in MDA3KP7.0AE3?
Per Microsemi's nomenclature guide in RF01243 Rev B, the "e3" suffix indicates full RoHS compliance with lead-free terminations meeting EU Directive 2011/65/EU and JEDEC J-STD-020B standards. It confirms the MDA3KP7.0AE3 uses annealed matte-tin plating-not tin-lead-and is compatible with Pb-free reflow profiles. This designation is laser-marked on the device body and verified through material declarations and test reports for the MDA3KP7.0AE3.
