Product details
Overview
MXDA3KP20AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 20 V standoff voltage (VWM), 22.2–24.5 V breakdown voltage (V(BR)), and 32.4 V clamping voltage (VC) at 92.6 A peak pulse current (IPP). 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 DC power rails.
For engineers reviewing the MXDA3KP20AE3 datasheet, MXDA3KP20AE3 pinout, MXDA3KP20AE3 application, or MXDA3KP20AE3 equivalent, key selection criteria include its 20 V working voltage, sub-100 ps response time, RoHS-compliant e3 marking, 150 °C max junction temperature, and compatibility with automated SMT assembly using standard 260 °C solder profiles.
Technical Context
The MXDA3KP20AE3 operates as a silicon avalanche diode-based unidirectional TVS, designed for parallel connection across protected lines to clamp overvoltage transients before they reach downstream ICs. Its 3000 W peak pulse power rating is specified at the 10/1000 µs waveform, with clamping performance validated up to 92.6 A IPP and <100 ps response time from 0 V to V(BR) min.
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 ID is ≤2 µA at 20 V VWM, supporting low-power system monitoring integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 20 V - Maximum continuous DC operating voltage before conduction begins; sets minimum system rail margin. |
| V(BR) min/max | 22.2–24.5 V - Breakdown occurs within this range at 1 mA; ensures predictable turn-on threshold. |
| VC @ IPP | 32.4 V - Clamped voltage at 92.6 A peak pulse; defines maximum stress on protected ICs. |
| PPP | 3000 W - Peak pulse power handling at 10/1000 µs; supports high-energy surge events. |
| ID @ VWM | ≤2 µA - Ultra-low standby leakage; avoids battery drain or signal path loading in always-on circuits. |
| TJ/TSTG | −55 to +150 °C - Wide operating and storage range; suitable for automotive under-hood and industrial control environments. |
Pinout & Package
MXDA3KP20AE3 uses a 3-pin surface-mount DO-214AB (SMC) package with void-free UL94V-0 epoxy body, matte-tin or tin-lead terminations, and polarity indicated by a dot marking pin 1. Odd-numbered pins (1 and 3) are cathodes; pin 2 is the common anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connected to protected line 1; conducts during overvoltage to shunt current to common anode. |
| Pin 2 | Common Anode | Shared return path for both TVS channels; must connect to system ground or low-impedance reference. |
| Pin 3 | Cathode of Channel 2 | Connected to protected line 2; enables dual-line protection (e.g., differential bus or redundant rails). |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables robust protection against IEC61000-4-5 Class 4 surges (42 Ω source) without derating at 25 °C. |
| Sub-100 ps response time | Clamps ESD transients before sensitive logic inputs are damaged, meeting IEC61000-4-2 Level 4 requirements. |
| RoHS-compliant e3 marking | Confirms lead-free termination and compliance with EU Directive 2011/65/EU for global market deployment. |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing cost and process complexity. |
| Full lot surge testing | Each production lot verified for PPP and VC performance, ensuring consistent reliability in mission-critical applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ20A | 600 W PPP rating, same 20 V VWM and DO-214AA package; lower clamping VC (32.4 V vs. 34.0 V) but reduced surge capacity. | Best suited for space-constrained consumer electronics where 600 W surge immunity suffices. | Select SMBJ20A only when peak impulse current remains below 29 A and board-level layout cannot accommodate larger SMC footprint. |
| SMCJ20A | 1500 W PPP rating, identical DO-214AB package and 20 V VWM; clamping VC = 32.4 V at 46.2 A IPP. | Appropriate for mid-tier industrial controls requiring higher reliability than SMBJ but less than MDA-class 3000 W systems. | Choose SMCJ20A if full 3000 W capability is unnecessary and cost optimization is prioritized without sacrificing package compatibility. |
Compared with SMBJ20A and SMCJ20A, MXDA3KP20AE3 delivers double the peak pulse power of SMCJ20A and five times that of SMBJ20A while retaining the same 20 V standoff and DO-214AB mechanical form factor-enabling drop-in upgrade paths in legacy designs requiring enhanced surge resilience.

FAQ
What is the clamping voltage of MXDA3KP20AE3 at its rated peak pulse current?
The MXDA3KP20AE3 has a maximum clamping voltage (VC) of 32.4 V at 92.6 A peak pulse current (IPP), measured under the 10/1000 µs waveform condition. This value defines the upper voltage limit imposed on protected circuitry during a full-rated surge event and is critical for ensuring downstream ICs remain within their absolute maximum ratings. The MXDA3KP20AE3 maintains this clamping performance across its full operating temperature range.
Is MXDA3KP20AE3 compatible with lead-free reflow soldering processes?
Yes, MXDA3KP20AE3 supports lead-free reflow soldering with a maximum solder temperature of 260 °C for 10 seconds, as specified in the datasheet. Its terminations are either annealed matte-tin or tin-lead, both compliant with MIL-STD-750 Method 2026. The e3 suffix confirms RoHS compliance, and the device's moisture sensitivity level is rated IPC/JEDEC J-STD-020B Level 1-no dry pack or baking is required prior to assembly.
How does the polarity configuration of MXDA3KP20AE3 affect PCB layout?
MXDA3KP20AE3 uses a unidirectional dual-channel configuration where pins 1 and 3 are cathodes and pin 2 is the common anode. This requires routing both protected lines (e.g., VCC and signal) to pins 1 and 3, while connecting pin 2 directly to a low-impedance ground plane. The dot marking on the package identifies pin 1, and incorrect orientation will prevent proper clamping. Layout must minimize trace inductance between the TVS and protected nodes to preserve sub-100 ps response efficacy.
Can MXDA3KP20AE3 be used for bidirectional signal line protection?
No, MXDA3KP20AE3 is a unidirectional TVS array and is not suitable for bidirectional AC or differential signal lines such as RS-485 or USB D+/D−. Its design assumes DC-biased operation with defined polarity: cathodes (pins 1 and 3) must be at higher potential than the common anode (pin 2). For bidirectional protection, Microsemi offers the C-suffix variants (e.g., MXDA3KP20CE3), which feature symmetrical breakdown in both directions and require no DC bias reference.
What IEC standards does MXDA3KP20AE3 meet for surge immunity?
MXDA3KP20AE3 meets IEC61000-4-5 for secondary lightning surge immunity (Class 1–4 with 42 Ω source impedance), IEC61000-4-2 for electrostatic discharge (ESD) up to ±15 kV air/±8 kV contact, and IEC61000-4-4 for electrical fast transients (EFT) up to 4 kV. These certifications are validated by its 3000 W peak pulse power rating, <100 ps response time, and clamping performance at rated IPP-making it suitable for EN 55032/55035 and MIL-STD-461G-compliant system designs.
