Product details
Overview
MXDA3KP17CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability secondary lightning protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD suppression per IEC61000-4-2, and EFT protection per IEC61000-4-4. It features a 17 V reverse standoff voltage (VWM), 18.9–20.9 V breakdown voltage (V(BR)), and clamps to ≤27.6 V at 106.6 A peak pulse current (IPP).
For engineers reviewing the MXDA3KP17CA datasheet, MXDA3KP17CA pinout, MXDA3KP17CA application, or MXDA3KP17CA equivalent, this device serves as a high-power, bidirectional surge protector for telecom interfaces, industrial control inputs, and DC power rails where fast response (<5 ns), low clamping voltage, and MIL-PRF-19500 upscreening capability are critical selection criteria.
Technical Context
The MXDA3KP17CA operates as a bidirectional avalanche diode array with symmetrical clamping behavior in both polarities. Its sub-5 ns response time enables effective suppression of ESD events and fast-rising transients, while its 3000 W peak pulse power rating (10/1000 µs waveform) supports robust protection against induced surges and switching transients.
It is rated for junction temperatures from –55 °C to +150 °C and exhibits ≤2 µA standby current at 17 V, ensuring minimal leakage in standby circuits. The device meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity and requires no dry pack handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 18.9–20.9 V @ 1 mA - Confirmed avalanche onset range; ensures reliable turn-on above operating voltage |
| VC @ IPP | ≤27.6 V @ 106.6 A - Clamping voltage during worst-case 10/1000 µs surge; limits downstream voltage stress |
| PPP | 3000 W @ 10/1000 µs - Peak surge energy absorption capacity under standardized lightning surge waveform |
| ID @ VWM | ≤2 µA - Ultra-low leakage at rated standoff voltage; avoids signal distortion or bias shift in high-impedance nodes |
| Response time | <5 ns - Time from 0 V to V(BR) min; enables protection against ESD and fast EFT pulses |
| TJ/TSTG | –55 to +150 °C - Full military-grade temperature range supporting operation in harsh environments |
Pinout & Package
MXDA3KP17CA uses a 3-pin surface-mount package with void-free thermosetting epoxy body (UL94V-0), tin-lead or matte-tin plating, and polarity defined by a dot marking indicating Pin 1. Odd-numbered pins (1 and 3) serve as cathodes for each TVS element in the dual-channel configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connected to protected line; conducts surge current to common reference when voltage exceeds V(BR) |
| Pin 2 | Anode (Common) | Shared anode node; ties both channels to ground or return path in bidirectional configuration |
| Pin 3 | Cathode of Channel 2 | Second protected line terminal; enables dual-line differential or independent single-line protection |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetric clamping on both polarities without external polarity reversal; ideal for AC-coupled or floating lines |
| 3000 W peak pulse power | Supports Class 4 secondary lightning protection per IEC61000-4-5 with 42 Ω source impedance |
| MIL-PRF-19500 upscreening option | Available with wafer/lot traceability, 3σ screening on ID, and conformance inspection for aerospace/defense programs |
| Level 1 moisture sensitivity | No dry pack required; compatible with standard SMT reflow profiles per J-STD-020B |
| Low clamping ratio (VC/VWM) | ≤1.62 - Minimizes overvoltage exposure to downstream ICs compared to competing 17 V TVS devices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17CA | 600 W PPP rating; same VWM and bidirectional polarity; DO-214AA package; 3.5 mm × 4.6 mm footprint vs. MXDA3KP17CA's 21.03 × 6.86 mm | Lower surge capacity suits consumer-grade 10/1000 µs events but not Class 4 IEC61000-4-5 compliance | Select SMBJ17CA only for cost-sensitive, non-military designs with <1 kA expected surge current |
| SMCJ17CA | 1500 W PPP; same VWM and polarity; DO-214AB package; 7.11 mm × 6.22 mm footprint; higher thermal resistance than MXDA3KP17CA | Limited to Class 2/3 lightning protection; insufficient for 42 Ω source impedance Class 4 testing | Choose SMCJ17CA when board space is constrained but full 3000 W capability is not required |
Compared with SMBJ17CA and SMCJ17CA, MXDA3KP17CA delivers double the surge power handling and verified MIL-PRF-19500 upscreening readiness-critical for infrastructure and defense systems where single-event survivability and lot traceability are mandatory.

FAQ
What is the clamping voltage of MXDA3KP17CA at its rated peak pulse current?
The MXDA3KP17CA has a maximum clamping voltage (VC) of 27.6 V when subjected to its rated peak pulse current (IPP) of 106.6 A under the 10/1000 µs waveform condition. This value is measured per Figure 2 in the official RF01243 datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. Designers use this parameter to verify that downstream components remain within their absolute maximum voltage ratings.
Is MXDA3KP17CA suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MXDA3KP17CA is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with a 42 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse power rating and ≤27.6 V clamping voltage ensure compliance when tested using the standardized 10/1000 µs surge waveform. It also supports Class 4 with 12 Ω and 2 Ω source impedances per documented test configurations.
What does the 'C' suffix in MXDA3KP17CA indicate?
The 'C' suffix in MXDA3KP17CA denotes bidirectional polarity, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. This is distinct from unidirectional variants (e.g., MXDA3KP17A), which conduct only during reverse-bias overvoltage. The bidirectional configuration makes MXDA3KP17CA appropriate for AC-coupled signals, differential buses, and floating references where polarity reversal may occur.
Does MXDA3KP17CA require special handling due to moisture sensitivity?
No, MXDA3KP17CA is classified as Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life and does not require dry pack storage or baking prior to soldering. Its void-free thermosetting epoxy package and matte-tin or tin-lead terminations are fully compatible with standard SnPb and lead-free reflow profiles, simplifying manufacturing integration.
Can MXDA3KP17CA be used for ESD protection per IEC61000-4-2?
Yes, MXDA3KP17CA is specified for ESD protection per IEC61000-4-2 due to its <5 ns response time and ability to suppress fast-rising transients. While optimized for higher-energy 10/1000 µs surges, its avalanche structure responds rapidly enough to clamp 8 kV contact and 15 kV air discharge events. However, for dedicated ESD-only applications with strict capacitance limits, lower-capacitance discrete diodes may be preferred alongside MXDA3KP17CA for layered protection.
