Product details
Overview
MADA3KP17AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in industrial power interfaces. It features a 17 V reverse standoff voltage (VWM), 18.9–20.9 V breakdown voltage (V(BR)), 27.6 V maximum clamping voltage at 106.6 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MADA3KP17AE3 datasheet, MADA3KP17AE3 pinout, MADA3KP17AE3 application, or MADA3KP17AE3 equivalent, key selection criteria include clamping performance under IEC61000-4-5 (42 Ω source), surge current handling at 10/1000 µs, RoHS-compliant matte-tin termination, and MIL-PRF-19500 upscreening eligibility for aerospace-grade reliability validation.
Technical Context
The MADA3KP17AE3 is a single-channel unidirectional TVS diode optimized for fast transient suppression in DC power rails and signal lines subject to lightning-induced surges or switching transients. Its <100 ps response time enables effective ESD (IEC61000-4-2) and EFT (IEC61000-4-4) mitigation without signal distortion.
It delivers 3000 W peak pulse power at 10/1000 µs waveform with 27.6 V clamping voltage at 106.6 A IPP, and maintains stable standby current (<2 µA at 17 V) over full temperature range. Polarity is defined by dot-marked Pin 1 as cathode per package marking convention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ17A | 600 W PPP rating, 27.6 V VC @ 21.5 A IPP - lower surge capacity | Targeted at consumer electronics with lower IEC61000-4-5 Class 2/3 requirements | Select SMAJ17A only if system-level surge testing confirms ≤600 W worst-case transient energy |
| 1.5KE17A | Through-hole TO-204AA package, 1500 W PPP, 27.6 V VC @ 54.3 A IPP - half the power rating | Legacy designs requiring axial-leaded replacement with manual assembly compatibility | Choose 1.5KE17A when board space allows through-hole mounting and surge duty cycle is infrequent |
Compared with SMAJ17A and 1.5KE17A, the MADA3KP17AE3 provides double the peak pulse power and higher surge current tolerance in a surface-mount package, making it suitable for high-energy industrial and telecom surge environments where compactness and reliability are prioritized.

FAQ
What is the clamping voltage of MADA3KP17AE3 at its rated peak pulse current?
The MADA3KP17AE3 has a maximum clamping voltage (VC) of 27.6 V at its rated peak pulse current (IPP) of 106.6 A under 10/1000 µs waveform conditions. This value is measured per standard TVS test methodology and ensures downstream components experience no more than 27.6 V during worst-case surge events. The MADA3KP17AE3 achieves this clamping performance while maintaining low leakage and fast response.
Is MADA3KP17AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MADA3KP17AE3 is RoHS compliant. The 'e3' suffix explicitly denotes matte-tin plating per JEDEC/IPC standards and full compliance with EU RoHS Directive 2011/65/EU. This ensures compatibility with lead-free reflow processes and eliminates hazardous substances including lead, cadmium, mercury, hexavalent chromium, PBB, and PBDE. The MADA3KP17AE3 meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity without dry pack.
Can MADA3KP17AE3 be used for bidirectional transient protection?
No, MADA3KP17AE3 is a unidirectional TVS device, as indicated by the absence of 'C' in its part number. It conducts only during positive transients relative to its anode. For bidirectional protection, Microsemi offers the MDA3KP17CE3 variant. Using MADA3KP17AE3 in AC or dual-polarity circuits without external polarity conditioning may result in unintended conduction or failure. Always verify polarity alignment before integrating the MADA3KP17AE3.
What is the maximum operating temperature range for MADA3KP17AE3?
The MADA3KP17AE3 supports a junction and storage temperature range of –55 °C to +150 °C. This wide thermal envelope enables deployment in under-hood automotive ECUs, industrial variable-frequency drives, and outdoor telecom cabinets. Derating curves in the datasheet show 100% power rating at 25 °C, decreasing linearly to ~50% at +125 °C. The MADA3KP17AE3 maintains specified electrical parameters across this full range when properly heatsinked.
Does MADA3KP17AE3 require upscreening to meet MIL-PRF-19500 requirements?
MADA3KP17AE3 is manufactured with baseline high-reliability wafer and assembly lot traceability but requires optional upscreening to achieve full MIL-PRF-19500 conformance. Screening options-including burn-in, temperature cycling, and parametric lot acceptance testing-are available per Micronote 129. Standard MADA3KP17AE3 units are not certified to MIL-PRF-19500 unless explicitly ordered with screening codes. Confirm screening level with order documentation for the MADA3KP17AE3.
