Product details
Overview
MXDA3KP30AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 30 V standoff voltage (VWM), 33.3–36.8 V breakdown voltage (V(BR)), and 48.4 V clamping voltage (VC) at 62 A peak pulse current. It provides secondary lightning protection per IEC61000-4-5 (42 Ω, Class 1–4), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in power supply input stages.
For engineers reviewing the MXDA3KP30AE3 datasheet, MXDA3KP30AE3 pinout, MXDA3KP30AE3 application, or MXDA3KP30AE3 equivalent, key selection criteria include its 30 V working voltage, 48.4 V clamping performance at 62 A, RoHS-compliant e3 marking, -55°C to +150°C operating range, and MIL-PRF-19500 upscreening capability for high-reliability aerospace and defense systems.
Technical Context
The MXDA3KP30AE3 operates as a unidirectional avalanche diode-based TVS array, designed for parallel connection across DC power rails to shunt transient energy to ground. Its sub-100 ps response time enables effective suppression of ESD events, while its 10/1000 µs waveform-rated 3000 W peak pulse power supports robust surge handling in industrial and telecom infrastructure.
It features a thermoset epoxy package rated UL94V-0, tin-lead or matte-tin terminations compliant with MIL-STD-750 Method 2026, and polarity defined by odd-numbered pins as cathodes. Standby leakage current is limited to ≤2 µA at 30 V, ensuring minimal impact on system quiescent power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff Voltage) | 30 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) Min/Max | 33.3–36.8 V @ 1 mA - Ensures reliable avalanche initiation above normal operating voltage |
| VC @ IPP | 48.4 V @ 62 A - Clamped voltage during 10/1000 µs surge, defining maximum stress on protected ICs |
| PPP | 3000 W @ 10/1000 µs - Peak transient power dissipation capability under standardized surge waveform |
| ID @ VWM | ≤2 µA - Ultra-low leakage preserves battery life and avoids false triggering in low-power circuits |
| TJ/TSTG Range | -55°C to +150°C - Supports operation in extended industrial, automotive under-hood, and aerospace environments |
| RoHS Status | e3 marking - Confirms lead-free, RoHS-compliant construction per JEDEC J-STD-020B Level 1 moisture sensitivity |
Pinout & Package
MXDA3KP30AE3 uses a 3-pin surface-mount package with void-free UL94V-0 thermosetting epoxy body. Pin 1 is cathode (marked by dot), Pin 2 is anode, and Pin 3 is cathode - consistent with unidirectional dual-channel configuration per MDA series nomenclature and polarity definition ("odd number pins are cathodes").
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Channel 1) | Connected to protected line; conducts surge current to ground when V > V(BR) |
| Pin 2 | Anode (Common) | Shared anode node tied to system ground or low-impedance return path |
| Pin 3 | Cathode (Channel 2) | Second protected line input; enables dual-rail or differential bus protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | 600 W PPP rating, SMB package, 48.4 V VC @ 12.3 A - lower surge capacity and smaller footprint | Targeted at consumer electronics and low-energy industrial interfaces where 3000 W is not required | Select SMBJ30A only when board space is constrained and surge threat level is Class 2 or lower per IEC61000-4-5 |
| SMCJ30A | 1500 W PPP rating, SMC package, 48.4 V VC @ 31 A - mid-tier power handling, larger than MXDA3KP30AE3 but smaller than DO-214AB | Suitable for general-purpose industrial power supplies lacking MIL-spec requirements | Choose SMCJ30A for cost-sensitive designs needing proven reliability but without upscreening or dual-channel layout needs |
Compared with SMBJ30A and SMCJ30A, MXDA3KP30AE3 delivers double the surge power rating of SMCJ30A and five times that of SMBJ30A, supports dual-line protection in one package, and offers optional MIL-PRF-19500 screening - making it uniquely suited for mission-critical infrastructure where failure is not an option.

FAQ
What is the clamping voltage of MXDA3KP30AE3 at its rated peak pulse current?
The MXDA3KP30AE3 has a maximum clamping voltage (VC) of 48.4 V at 62 A peak pulse current (IPP), measured under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is critical for ensuring downstream ICs remain within absolute maximum ratings. The MXDA3KP30AE3 maintains this clamping performance across its full operating temperature range.
Is MXDA3KP30AE3 RoHS-compliant and what does the 'e3' suffix indicate?
Yes, MXDA3KP30AE3 is RoHS-compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide. The 'e3' designation specifies matte-tin plating and lead-free construction meeting EU RoHS Directive 2011/65/EU requirements. It also indicates compliance with IPC/JEDEC J-STD-020B Level 1 moisture sensitivity, eliminating the need for dry-pack packaging or baking prior to reflow soldering.
Does MXDA3KP30AE3 support MIL-PRF-19500 high-reliability screening?
Yes, MXDA3KP30AE3 supports optional MIL-PRF-19500 upscreening, including wafer fabrication and assembly lot traceability, 3σ lot norm screening on standby current (ID), and conformance inspections aligned with military standards. This capability is documented in Micronote 129 and makes MXDA3KP30AE3 suitable for aerospace, defense, and other high-assurance applications where component pedigree and defect prevention are mandatory.
How many protected channels does MXDA3KP30AE3 provide and how is polarity configured?
MXDA3KP30AE3 provides two independent unidirectional TVS channels in a single 3-pin package. Per the datasheet, odd-numbered pins (Pin 1 and Pin 3) serve as cathodes, while Pin 2 is the common anode. This configuration allows simultaneous protection of two separate lines - such as dual-rail power inputs or differential signal pairs - referenced to a shared ground plane without requiring discrete devices.
What is the maximum standoff voltage and leakage current specification for MXDA3KP30AE3?
The MXDA3KP30AE3 has a rated reverse standoff voltage (VWM) of 30 V, meaning it remains non-conductive up to this DC or peak AC voltage. At this voltage and 25°C, its maximum standby current (ID) is 2 µA - a value verified across production lots and critical for low-power and battery-operated systems where parasitic drain must be minimized. The MXDA3KP30AE3 maintains this ultra-low leakage across its full -55°C to +150°C operating range.
