Product details
Overview
MDA3KP16CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, designed for high-reliability secondary lightning and ESD protection. It features a 16 V reverse 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 operates from –55 °C to +150 °C.
For engineers reviewing the MDA3KP16CA datasheet, MDA3KP16CA pinout, MDA3KP16CA application, or MDA3KP16CA equivalent, key selection criteria include IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω/2 Ω source impedances, bidirectional polarity, 100 ps response time, and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
The MDA3KP16CA is a silicon avalanche diode-based TVS array optimized for fast clamping of high-energy transients. Its bidirectional construction enables symmetrical surge suppression across both polarities without external polarity management, and its 10/1000 µs waveform rating supports IEC61000-4-5 Level 4 testing under 42 Ω source impedance.
It delivers 3000 W peak pulse power with <100 ps response time, clamps at ≤26.0 V under 115.4 A IPP, and maintains ≤2 µA standby current at 16 V VWM. The device is wafer-lot traceable, surge-tested per unit, and moisture-rated IPC/JEDEC J-STD-020B Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous operating voltage before clamping begins; matches 12–15 V DC bus systems with safety margin. |
| V(BR) min/max | 17.8–19.7 V - Confirmed avalanche onset range at 1 mA; ensures predictable turn-on above nominal rail. |
| VC @ IPP | 26.0 V @ 115.4 A - Clamping voltage during full 10/1000 µs surge; limits downstream IC stress below 26 V. |
| PPP | 3000 W - Peak pulse power handling at 10/1000 µs; supports industrial-grade lightning immunity per IEC61000-4-5. |
| TJ/TSTG | –55 to +150 °C - Extended thermal range enables use in automotive engine bays and outdoor telecom enclosures. |
| ID @ VWM | ≤2 µA - Ultra-low leakage preserves battery life in always-on monitoring circuits and low-power sensors. |
| Response time | <100 ps - Near-instantaneous avalanche conduction prevents ESD-induced latch-up in sensitive analog front-ends. |
Pinout & Package
MDA3KP16CA 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 mass, and polarity marked with dot indicating Pin 1 (cathode for unidirectional variants; symmetric for bidirectional). Pin 1 and Pin 2 are electrically identical terminals of the bidirectional TVS junction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | Common terminal of symmetrical avalanche junction; connects to protected line (e.g., RS-485 A/B or USB D+/D–). |
| Pin 2 | Anode/Cathode (bidirectional) | Electrically identical to Pin 1; forms differential or common-mode clamp path between two nodes or to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection of AC-coupled or differential signal lines (e.g., CAN, RS-485) without polarity awareness. |
| IEC61000-4-5 Class 1–4 compliance | Validated for secondary lightning surges up to 4 kV with 42 Ω, 12 Ω, and 2 Ω source impedances-covers telecom, industrial control, and building automation. |
| RoHS-compliant e3 marking | Matte-tin plating meets JEDEC J-STD-020B Level 1 moisture sensitivity; eliminates dry-pack requirement and supports lead-free reflow. |
| 3σ lot norm screening on ID | Guarantees ≤2 µA leakage across production lots-critical for long-life battery-powered IoT sensor nodes. |
| Wafer and assembly lot traceability | Supports aerospace and defense programs requiring full material pedigree and failure analysis traceability per MIL-PRF-19500. |

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, same VWM and bidirectional configuration, DO-214AA package (smaller footprint, lower thermal mass). | Limited to IEC61000-4-5 Class 2/3; insufficient for 42 Ω Class 4 lightning tests. | Select when space-constrained layouts prioritize footprint over 3000 W surge capacity. |
| 1.5KE16CA | 3000 W PPP, axial-leaded DO-15 package, higher thermal resistance, no MIL-PRF-19500 screening option. | Not suitable for automated SMT assembly; lacks lot traceability and moisture-level certification. | Choose only for prototyping or non-production through-hole designs where reliability traceability is not required. |
Compared with SMBJ16CA and 1.5KE16CA, the MDA3KP16CA uniquely combines 3000 W surge capability, DO-214AB SMT compatibility, MIL-PRF-19500 upscreening eligibility, and IEC61000-4-5 Class 4 validation-making it the only option qualified for high-reliability industrial and defense surge protection.

FAQ
What is the clamping voltage of the MDA3KP16CA at its rated peak pulse current?
The MDA3KP16CA 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 per Figure 2 in the official datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MDA3KP16CA maintains this clamping performance across its full operating temperature range of –55 °C to +150 °C.
Is the MDA3KP16CA suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, the MDA3KP16CA is explicitly validated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. It also supports Class 1–3 with 12 Ω and Class 2–4 with 2 Ω source impedances. The MDA3KP16CA achieves this with its 3000 W peak pulse power rating and sub-100 ps response time-key requirements for Class 4 compliance.
What does the 'C' suffix in MDA3KP16CA indicate?
The 'C' suffix in MDA3KP16CA denotes bidirectional polarity, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., MDA3KP16A), the MDA3KP16CA has no anode/cathode distinction-Pins 1 and 2 are functionally identical terminals of a center-tapped avalanche junction. This makes the MDA3KP16CA ideal for protecting AC-coupled or differential interfaces such as RS-485, CAN, or Ethernet PHY lines.
Does the MDA3KP16CA require dry packing or special moisture handling?
No, the MDA3KP16CA is rated IPC/JEDEC J-STD-020B Level 1 for moisture sensitivity, meaning it has no floor life limitation and does not require dry packing or baking prior to reflow soldering. Its void-free UL94V-0 epoxy body and matte-tin plating ensure robust solderability per MIL-STD-750 Method 2026. This simplifies manufacturing logistics and eliminates moisture-related defects in high-volume SMT assembly of the MDA3KP16CA.
Can the MDA3KP16CA be used in automotive under-hood applications?
Yes, the MDA3KP16CA is rated for junction temperatures from –55 °C to +150 °C and is eligible for MIL-PRF-19500 upscreening-making it suitable for automotive under-hood applications such as body control modules and engine control sensor interfaces. Its 115.4 A peak pulse current rating and 26.0 V clamping voltage protect against ISO 7637-2 load dump and inductive switching transients. While not AEC-Q200 certified out-of-box, upscreened MDA3KP16CA units meet automotive reliability requirements.
