Product details
Overview
MXDA3KP16CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, featuring 16 V standoff voltage (VWM), 17.8–19.7 V breakdown voltage (V(BR)), 26.0 V maximum clamping voltage (VC) at 115.4 A peak pulse current, and <5 ns response time - deployed for secondary lightning protection and ESD/EFT hardening in telecom power interfaces.
For engineers reviewing the MXDA3KP16CA datasheet, MXDA3KP16CA pinout, MXDA3KP16CA application, or MXDA3KP16CA equivalent, key selection criteria include bidirectional polarity, IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω source impedances, 150 °C junction temperature rating, and RoHS-compliant matte-tin termination.
Technical Context
The MXDA3KP16CA implements a symmetrical avalanche diode structure enabling bidirectional transient suppression without polarity sensitivity. It delivers 3000 W peak pulse power at 10/1000 µs waveform with clamping voltage tightly bounded at 26.0 V under 115.4 A surge, and maintains sub-5 ns response time to limit voltage overshoot during fast transients.
Designed for high-reliability environments, it undergoes 3σ lot norm screening on standby current (ID ≤ 2 µA @ VWM), full surge testing per MIL-PRF-19500 screening options, and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - eliminating dry-pack requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before conduction begins |
| V(BR) min/max | 17.8–19.7 V @ 1 mA - guaranteed avalanche onset range defining turn-on threshold |
| VC @ IPP | 26.0 V @ 115.4 A - clamped voltage during worst-case 10/1000 µs surge, limiting downstream stress |
| PPP | 3000 W @ 10/1000 µs - peak power dissipation capability for standardized lightning surge waveforms |
| Response time | <5 ns - time from 0 V to V(BR) min, critical for ESD (IEC61000-4-2) and EFT (IEC61000-4-4) immunity |
| ID @ VWM | ≤2 µA - leakage current at rated standoff, ensuring minimal power loss in standby systems |
| TJ/TSTG | −55 to +150 °C - operational and storage temperature range supporting industrial and aerospace deployments |
Pinout & Package
MXDA3KP16CA uses a DO-214AB (SMC) surface-mount package: void-free UL94V-0 epoxy body, matte-tin plated terminals solderable per MIL-STD-750 Method 2026, 5 g typical weight, and polarity marked by dot indicating Pin 1 (cathode for unidirectional variants; symmetrical for bidirectional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (Bidirectional) | One terminal of symmetrical avalanche junction; no fixed polarity - connects to protected line |
| Pin 2 | Cathode (Bidirectional) | Second terminal of symmetrical avalanche junction; interchangeable with Pin 1 in layout |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables AC-line or differential-signal protection without polarity awareness or external circuitry |
| IEC61000-4-5 Class 1–4 compliance | Validated for secondary lightning surges with 42 Ω, 12 Ω, and 2 Ω source impedances per standard test configurations |
| RoHS-compliant e3 marking | Matte-tin plating meets lead-free assembly requirements and eliminates Pb-based solder compatibility concerns |
| Moisture sensitivity Level 1 | No dry-pack or bake-out required prior to reflow, reducing manufacturing overhead and handling risk |
| 3σ lot norm screening on ID | Statistical control of leakage ensures consistent low-power behavior across production lots |
Applications
| Telecom Power Feeds | Industrial Ethernet Ports |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | 600 W PPP rating, SMB package (smaller footprint), 28.5 V VC @ 21.5 A IPP | Lower energy handling; suitable only for ESD/EFT, not secondary lightning | Select when space-constrained and surge threat level is limited to IEC61000-4-2/4-4 only |
| 1.5KE16CA | Through-hole DO-201AE package, same 16 V VWM and bidirectional polarity, 26.5 V VC @ 113 A IPP | Requires PCB through-hole mounting; lacks surface-mount process compatibility and MIL-PRF-19500 screening | Choose for legacy designs where rework to SMT is impractical and high-reliability screening is not mandated |
Compared with SMBJ16CA and 1.5KE16CA, MXDA3KP16CA provides triple the peak pulse power (3000 W vs. 600 W or ~1500 W), DO-214AB SMT compatibility, and optional MIL-PRF-19500 upscreening - making it uniquely suited for high-energy, high-reliability industrial and telecom surge protection.

FAQ
What is the clamping voltage of MXDA3KP16CA at its rated peak pulse current?
The MXDA3KP16CA 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 RF01243 datasheet and defines the upper voltage limit imposed on protected circuits during worst-case surge events. The low VC ensures downstream components such as DC/DC controllers or interface ICs remain within safe operating limits.
Is MXDA3KP16CA suitable for IEC61000-4-5 secondary lightning protection?
Yes, MXDA3KP16CA is validated for IEC61000-4-5 secondary lightning protection across Class 1–4 with 42 Ω, 12 Ω, and 2 Ω source impedances. Its 3000 W peak pulse power rating and 26.0 V clamping voltage meet the energy-handling and voltage-limiting requirements defined in the standard for equipment connected to AC mains or long-distance signal lines. The bidirectional configuration supports both line-to-line and line-to-ground surge paths.
Does MXDA3KP16CA require dry-pack handling prior to reflow soldering?
No, MXDA3KP16CA has IPC/JEDEC J-STD-020B moisture sensitivity Level 1 rating, meaning it may be stored indefinitely at ambient conditions without desiccant or dry-pack packaging. This eliminates pre-reflow baking steps and reduces manufacturing complexity and cost - a key advantage over higher-MSL-rated TVS devices in high-volume SMT production.
What does the "C" suffix in MXDA3KP16CA indicate?
The "C" suffix in MXDA3KP16CA explicitly denotes bidirectional polarity, confirming symmetrical avalanche characteristics between both terminals. Unlike unidirectional variants (e.g., MXDA3KP16A), this version conducts equally in either direction above V(BR), making it ideal for AC-coupled lines, differential data buses, or any application where voltage polarity reversal cannot be guaranteed or controlled.
How is the polarity marked on the MXDA3KP16CA package?
MXDA3KP16CA uses a dot marking on the top surface of the DO-214AB (SMC) package to identify Pin 1. Although the device is bidirectional, the dot aligns with industry-standard orientation for consistency in automated placement and visual inspection. Per datasheet Page 2, "Odd number pins are cathodes of each TVS" - but for bidirectional types like MXDA3KP16CA, this refers to internal symmetry rather than functional polarity, and both terminals behave identically.
