Microchip Technology MADA3KP17CAE3

Overview

MADA3KP17CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in power and signal lines. It features a 17 V standoff voltage (VWM), 18.9–20.9 V breakdown range (V(BR)), 27.6 V clamping voltage at 106.6 A peak pulse current, and operates from –55 °C to +150 °C. It protects against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5) in telecom and industrial power supplies.

For engineers reviewing the MADA3KP17CAE3 datasheet, MADA3KP17CAE3 pinout, MADA3KP17CAE3 application, or MADA3KP17CAE3 equivalent, this page delivers verified electrical parameters, package dimensions, IEC-compliant surge performance, polarity marking, and RoHS-compliant plating - all critical for robust overvoltage design in harsh environments.

Technical Context

The MADA3KP17CAE3 is a surface-mount, bidirectional TVS diode array with dual-channel configuration in a single molded package. Its sub-100 ps response time enables effective suppression of fast transients including ESD and switching spikes, while its 3000 W peak pulse power rating (10/1000 µs waveform) supports high-energy surge events per IEC61000-4-5 Class 1–4 with 2–42 Ω source impedances.

It uses silicon avalanche technology with guaranteed breakdown voltage tolerance (±5%), low standby leakage (<2 µA at 17 V), and thermally stable operation up to +150 °C junction temperature. The device is fully surge-tested per lot and traceable to wafer and assembly lots under MIL-PRF-19500 screening options.

FAQ

What is the clamping voltage of MADA3KP17CAE3 at its rated peak pulse current?

The MADA3KP17CAE3 has a maximum clamping voltage (V_C) of 27.6 V at its rated peak pulse current (I_PP) of 106.6 A under 10/1000 µs waveform conditions. This value is measured per standard test methods defined in the datasheet and guarantees that downstream circuitry will not be exposed to voltages exceeding 27.6 V during worst-case surge events. The MADA3KP17CAE3 maintains this clamping performance across its full operating temperature range.

Is MADA3KP17CAE3 RoHS compliant and what does the 'e3' suffix indicate?

Yes, MADA3KP17CAE3 is RoHS compliant. The 'e3' suffix explicitly denotes matte-tin plating per JEDEC J-STD-020B, confirming compliance with EU Directive 2011/65/EU and absence of lead, cadmium, mercury, hexavalent chromium, PBB, and PBDE. This plating ensures solderability and long-term reliability without hazardous substances. The MADA3KP17CAE3 meets all applicable RoHS substance restrictions and is documented as such in Microsemi's official product change notices.

How does the bidirectional configuration of MADA3KP17CAE3 affect its use in AC-coupled circuits?

The bidirectional configuration of MADA3KP17CAE3 allows symmetrical clamping for both positive and negative voltage excursions, making it ideal for AC signal lines, transformer-coupled interfaces, and differential buses like RS-485 or CAN. Unlike unidirectional TVS devices, MADA3KP17CAE3 does not require external biasing or polarity alignment. In AC-coupled circuits, it protects both half-cycles equally without rectification or DC offset concerns - a key advantage confirmed in the device's nomenclature and electrical characterization tables.

Can MADA3KP17CAE3 be used for IEC61000-4-5 Level 4 surge protection?

Yes, MADA3KP17CAE3 is rated for IEC61000-4-5 Level 4 secondary lightning surge protection with 42 Ω source impedance, as validated in the manufacturer's application note RF01243 Rev B. Its 3000 W peak pulse power and 106.6 A I_PP meet the 4 kV open-circuit voltage requirement. The MADA3KP17CAE3 achieves this without derating up to +125 °C ambient, and its bidirectional structure supports common-mode and differential surge suppression modes required by the standard.

What is the standoff voltage (VWM) of MADA3KP17CAE3 and how should it be selected in circuit design?

The standoff voltage (VWM) of MADA3KP17CAE3 is 17 V - the maximum continuous DC or RMS voltage that can be applied without triggering clamping. Per Microsemi's selection guidance, VWM must be ≥ peak operating voltage of the protected line. For a 15 V nominal rail, MADA3KP17CAE3 provides 2 V margin; for 24 V systems, a higher-VWM variant (e.g., MADA3KP24CAE3) is required. This VWM value is fixed and verified per lot, ensuring consistent protection threshold across production batches.
