Product details
Overview
MXDA3KP16CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability surge protection of DC power lines and signal interfaces. It features a 16 V reverse standoff voltage (VWM), 17.8–19.7 V breakdown voltage (V(BR)), 26.0 V maximum clamping voltage at 115.4 A peak pulse current, and operates from –55 °C to +150 °C - used in industrial power supply input stages and telecom line cards.
For engineers reviewing the MXDA3KP16CAE3 datasheet, MXDA3KP16CAE3 pinout, MXDA3KP16CAE3 application, or MXDA3KP16CAE3 equivalent, key selection criteria include bidirectional clamping capability, IEC61000-4-5 secondary lightning compliance with 42 Ω source impedance (Class 1–4), 10/1000 µs surge rating, RoHS-compliant e3 termination, and polarity-defined pin 1 marking for correct PCB orientation.
Technical Context
This TVS array uses silicon avalanche diode technology to provide sub-nanosecond response (<5 ns) to fast transients. Its bidirectional construction enables symmetrical clamping on AC-coupled or floating lines without polarity concerns, and it meets MIL-PRF-19500 screening options for high-reliability programs.
The device is rated for 3000 W peak pulse power at 10/1000 µs waveform, with clamping performance validated up to 115.4 A IPP and derated linearly above 25 °C per Figure 3. Standby leakage is limited to ≤2 µA at 16 V, supporting low-power system monitoring integrity.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package | Lower surge capacity; suitable only for IEC61000-4-2/4-4, not Class 4 lightning | Select when space-constrained layouts require smaller footprint and surge threat level is limited to ESD/EFT |
| SMCJ16CA | 1500 W PPP, same VWM and polarity, DO-214AB package, higher thermal mass than MXDA3KP16CAE3 | Insufficient for 42 Ω IEC61000-4-5 Class 4; requires parallel devices for 3000 W equivalence | Choose if legacy board design uses SMC package and surge requirements are capped at Class 3 (12 Ω source) |
Compared with SMBJ16CA and SMCJ16CA, MXDA3KP16CAE3 delivers double the surge power handling of SMCJ16CA and five times that of SMBJ16CA within a dedicated high-reliability surface-mount array, enabling single-device Class 4 lightning protection without layout redesign or paralleling.

FAQ
What is the clamping voltage of MXDA3KP16CAE3 at its rated peak pulse current?
The MXDA3KP16CAE3 has a maximum clamping voltage (VC) of 26.0 V at its rated peak pulse current (IPP) of 115.4 A under 10/1000 µs waveform conditions. This value is measured across the device terminals during full surge stress and defines the upper voltage limit imposed on protected circuitry - critical for ensuring downstream ICs remain within absolute maximum ratings during transient events.
Is MXDA3KP16CAE3 compliant with RoHS and what does the 'e3' suffix indicate?
The 'e3' suffix in MXDA3KP16CAE3 confirms full compliance with EU RoHS Directive 2011/65/EU, indicating lead-free matte-tin plating on all terminations. This designation replaces legacy tin-lead finishes and ensures compatibility with modern Pb-free reflow profiles while maintaining solderability per MIL-STD-750 Method 2026 - verified across all production lots of MXDA3KP16CAE3.
How does the bidirectional configuration of MXDA3KP16CAE3 affect its use in DC circuits?
MXDA3KP16CAE3's bidirectional structure allows it to clamp both positive- and negative-going transients symmetrically, making it ideal for DC circuits with potential reverse-polarity faults or coupled noise - such as 24 V industrial sensors or CAN bus stubs. Unlike unidirectional TVS devices, MXDA3KP16CAE3 requires no external polarity reversal circuitry and protects regardless of transient polarity relative to ground.
Can MXDA3KP16CAE3 be used for IEC61000-4-5 Class 4 lightning protection?
Yes, MXDA3KP16CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, as confirmed in the manufacturer's application table on page 1. Its 3000 W peak pulse power rating and 26.0 V clamping voltage ensure compliance without derating - provided layout follows recommended pad dimensions and grounding practices specified in the MXDA3KP16CAE3 datasheet.
What is the junction temperature range and how does it impact field deployment of MXDA3KP16CAE3?
MXDA3KP16CAE3 operates across a junction temperature range of –55 °C to +150 °C, enabling deployment in extreme environments including under-hood automotive ECUs, outdoor base stations, and industrial ovens. This wide range eliminates need for external thermal derating in most applications, though peak pulse power must be reduced linearly above 25 °C per the derating curve in Figure 3 of the MXDA3KP16CAE3 datasheet.
