Product details
Overview
MDA3KP9.0AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability overvoltage protection in power rails and signal lines. It features a 9.0 V reverse standoff voltage (VWM), 10.0–11.1 V breakdown voltage (V(BR)), 15.4 V maximum clamping voltage at 194.8 A peak pulse current, and operates across –55 °C to +150 °C junction temperature - deployed in industrial motor drives and telecom power supplies.
For engineers reviewing the MDA3KP9.0AE3 datasheet, MDA3KP9.0AE3 pinout, MDA3KP9.0AE3 application, or MDA3KP9.0AE3 equivalent, key selection criteria include IEC 61000-4-5 secondary lightning compliance (Class 4 @ 2 Ω source), 100 ps response time, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility for aerospace-grade reliability validation.
Technical Context
The MDA3KP9.0AE3 employs an avalanche diode structure optimized for fast transient suppression with sub-100 ps response. Its unidirectional polarity defines odd-numbered pins as cathodes, enabling precise placement in DC-biased protection paths without reverse conduction risk.
Rated for 3000 W peak pulse power at 10/1000 µs waveform, it delivers 15.4 V clamping at 194.8 A while maintaining ≤10 µA standby current at 9.0 V - ensuring minimal leakage in always-on systems such as base station power management and railway signaling interfaces.
Key Specifications

|---|---|
| VWM | 9.0 V - maximum continuous DC or peak AC voltage the device blocks without clamping |
| V(BR) min/max | 10.0–11.1 V at 1 mA - ensures reliable avalanche initiation above operating rail |
| VC @ IPP | 15.4 V at 194.8 A - limits downstream voltage stress during 10/1000 µs surge events |
| ID @ VWM | ≤10 µA - negligible leakage current preserves efficiency in low-power standby circuits |
| PPP | 3000 W @ 10/1000 µs - meets IEC 61000-4-5 Class 4 requirements with 2 Ω source impedance |
| TJ range | –55 °C to +150 °C - supports operation in under-hood automotive ECUs and industrial inverters |
| RoHS | e3 suffix - lead-free matte-tin termination compliant with JEDEC J-STD-020B Level 1 moisture sensitivity |
Pinout & Package
MDA3KP9.0AE3 uses a 3-pin SMC (DO-214AB) surface-mount package with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity defined by dot marking indicating Pin 1 (cathode). Weight ≈5 g; dimensions per RF01243 Rev B: 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 |
|---|---|---|---|
| SMBJ9.0A | 600 W PPP rating, same VWM and VC but lower IPP (64.5 A) | Not suitable for IEC 61000-4-5 Class 4; limited to Class 2/3 with higher source impedances | Select when space-constrained layouts require SMB package and surge energy is ≤600 W |
| SMCJ9.0A | 1500 W PPP, 10.0–11.1 V V(BR), 15.4 V VC - identical clamping but half the energy rating | Valid for Class 3 lightning protection only; insufficient for 2 Ω source impedance Class 4 testing | Choose where cost optimization is prioritized and full 3000 W capability is not required |
Compared with SMBJ9.0A and SMCJ9.0A, the MDA3KP9.0AE3 delivers double the pulse power handling of SMCJ9.0A and five times that of SMBJ9.0A - enabling single-device compliance with stringent Class 4 secondary lightning standards without parallel stacking.

FAQ
What is the clamping voltage of MDA3KP9.0AE3 at its rated peak pulse current?
The MDA3KP9.0AE3 has a maximum clamping voltage (VC) of 15.4 V at its rated peak pulse current (IPP) of 194.8 A under 10/1000 µs waveform conditions. This value is guaranteed per RF01243 Rev B and ensures downstream components experience no more than 15.4 V during worst-case surge events - critical for protecting 12 V logic interfaces and microcontroller I/O pins. The MDA3KP9.0AE3 achieves this with sub-100 ps response time and tight V(BR) tolerance (10.0–11.1 V).
Is MDA3KP9.0AE3 suitable for IEC 61000-4-5 Class 4 secondary lightning protection?
Yes, MDA3KP9.0AE3 is explicitly rated for IEC 61000-4-5 Class 4 secondary lightning protection when tested with a 2 Ω source impedance, as confirmed in RF01243 Rev B page 1. Its 3000 W peak pulse power rating and 15.4 V clamping voltage enable compliance without derating or parallel devices. The MDA3KP9.0AE3 achieves this performance across –55 °C to +150 °C, making it suitable for outdoor telecom cabinets and railway infrastructure.
Does MDA3KP9.0AE3 have RoHS compliance and what does the 'e3' suffix indicate?
The 'e3' suffix in MDA3KP9.0AE3 denotes RoHS-compliant matte-tin plating per JEDEC J-STD-020B Level 1 moisture sensitivity - meaning no dry pack is required prior to reflow. This eliminates moisture-related popcorning during soldering and ensures compatibility with lead-free assembly processes. The MDA3KP9.0AE3 maintains full electrical specifications under RoHS constraints, including ≤10 µA standby current and 15.4 V clamping voltage.
How does the pin configuration of MDA3KP9.0AE3 support dual-channel protection?
MDA3KP9.0AE3 uses a 3-pin SMC package with Pins 1 and 3 as cathodes and Pin 2 as the common anode - enabling dual independent protection paths sharing one ground reference. This allows simultaneous safeguarding of two separate 9 V rails (e.g., analog and digital domains) without cross-talk. The MDA3KP9.0AE3 polarity marking (dot on Pin 1) ensures correct orientation during automated placement, critical for functional safety in rail signaling hardware.
Can MDA3KP9.0AE3 be used for ESD protection per IEC 61000-4-2?
Yes, MDA3KP9.0AE3 is qualified for ESD protection per IEC 61000-4-2 due to its <100 ps response time and low clamping voltage - verified in RF01243 Rev B page 1. It suppresses contact discharges up to ±15 kV by clamping within the first nanosecond, preventing latch-up in microcontrollers and interface ICs. The MDA3KP9.0AE3's 10 µA standby current at 9.0 V ensures no impact on signal integrity in high-impedance sensor lines.
