Product details
Overview
MXDA3KP16AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 16 V standoff voltage (VWM), 17.8–19.7 V breakdown range (V(BR)), and 26.0 V maximum clamping voltage (VC) at 115.4 A peak pulse current. 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 industrial power interfaces.
For engineers reviewing the MXDA3KP16AE3 datasheet, MXDA3KP16AE3 pinout, MXDA3KP16AE3 application, or MXDA3KP16AE3 equivalent, key selection criteria include verified 16 V working standoff, sub-100 ps response time, RoHS-compliant e3 marking, 150 °C max junction temperature, and compatibility with MIL-PRF-19500 upscreening for high-reliability deployments.
Technical Context
The MXDA3KP16AE3 operates as a unidirectional avalanche diode-based TVS array optimized for fast transient suppression in DC power rails and signal lines. Its design centers on low clamping ratio (VC/VWM ≈ 1.625), guaranteed 115.4 A IPP at 10/1000 µs waveform, and <100 ps response from 0 V to V(BR) min.
It features void-free UL94V-0 epoxy packaging, tin-lead or matte-tin terminations compliant with MIL-STD-750 Method 2026, and polarity defined by odd-numbered pins as cathodes. Temperature derating follows Figure 3, maintaining ≥80% PPP rating up to +100 °C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | 600 W PPP rating, 21.2 V VC @ 32.4 A IPP, DO-214AA package | Limited to lower-energy transients; not qualified for MIL-PRF-19500 screening | Select when cost-sensitive designs require basic IEC61000-4-2/4-4 compliance without Class 4 lightning robustness |
| SMCJ16A | 1500 W PPP rating, 26.0 V VC @ 57.7 A IPP, DO-214AB package | Half the peak power handling; lacks UL94V-0 case and Level 1 MSL rating | Choose where space constraints favor larger SMC footprint but 3000 W capability is not mandatory |
Compared with SMBJ16A and SMCJ16A, MXDA3KP16AE3 delivers double the surge energy handling of SMCJ16A and five times that of SMBJ16A while maintaining identical 16 V VWM and tighter clamping tolerance-enabling single-device replacement in legacy 3 kV/3 kA test environments.

FAQ
What is the clamping voltage of MXDA3KP16AE3 at its rated peak pulse current?
The MXDA3KP16AE3 has a maximum clamping voltage (VC) of 26.0 V at its specified peak pulse current (IPP) of 115.4 A under 10/1000 µs waveform conditions. This value is measured per Figure 2 in the official datasheet and ensures downstream circuitry remains below safe overvoltage thresholds during surge events.
Is MXDA3KP16AE3 RoHS-compliant and what does the 'e3' suffix indicate?
Yes, MXDA3KP16AE3 is RoHS-compliant. The 'e3' suffix explicitly denotes matte-tin plating per JEDEC J-STD-020 and full compliance with EU Directive 2011/65/EU. This replaces legacy tin-lead terminations while maintaining solderability and reliability per MIL-STD-750 Method 2026.
Does MXDA3KP16AE3 support MIL-PRF-19500 screening and what does that entail?
MXDA3KP16AE3 supports optional MIL-PRF-19500 upscreening, including wafer lot traceability, 3σ screening on standby current (ID), and conformance inspections. This qualification is documented in Micronote 129 and enables use in aerospace, defense, and other high-assurance applications requiring certified reliability data.
What is the maximum operating temperature range for MXDA3KP16AE3?
MXDA3KP16AE3 is rated for junction and storage temperatures from −55 °C to +150 °C. Its thermal performance maintains ≥80% of rated peak pulse power up to +100 °C ambient, as shown in Figure 3 of the datasheet, making it suitable for enclosed industrial and transportation environments.
How is polarity identified on the MXDA3KP16AE3 package and why does it matter?
Polarity on MXDA3KP16AE3 is defined by a dot marking Pin 1 on the top surface; odd-numbered pins (1 and 3) are cathodes. Correct orientation is essential because MXDA3KP16AE3 is unidirectional-reversal would prevent proper clamping and risk catastrophic failure during overvoltage events.
