Product details
Overview
MDA3KP16CAE3 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 standoff voltage (VWM), 17.8–19.7 V breakdown range (V(BR)), 26.0 V max clamping voltage at 115.4 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MDA3KP16CAE3 datasheet, MDA3KP16CAE3 pinout, MDA3KP16CAE3 application, or MDA3KP16CAE3 equivalent, this device serves as a RoHS-compliant, MIL-PRF-19500 upscreenable TVS for IEC61000-4-2/4-4/4-5-compliant surge protection in industrial power supplies, telecom interfaces, and automotive ECUs requiring stable clamping under 10/1000 µs transients.
Technical Context
The MDA3KP16CAE3 implements a bidirectional avalanche diode structure optimized for fast response (<5 ns) and low clamping ratio (VC/V(BR) ≈ 1.38). Its 3000 W peak pulse power rating is validated per 10/1000 µs waveform with ≤0.05% duty factor, and it maintains full surge capability across –55 °C to +150 °C junction temperature.
Designed for vertical mounting on PCBs, the device uses void-free UL94V-0 epoxy packaging with tin-lead or matte-tin terminations. Polarity is defined by dot marking: odd-numbered pins are cathodes, confirming dual-diode anti-parallel configuration for symmetrical bidirectional clamping.

Applications
| Industrial Power Supplies | Telecom Line Interfaces |
|---|---|
Use Scenario: Protecting 24 V DC input rails in programmable logic controllers against inductive switching spikes and lightning-induced surges. IC Role / Device Role / Timing Role: Primary transient voltage suppressor placed at board edge, shunting surge current away from DC-DC converters and microcontrollers. Use Value: Limits clamped voltage to 26.0 V during 115.4 A transients, preventing latch-up or gate oxide damage in downstream 3.3 V/5 V logic. | Use Scenario: Shielding RS-485 transceivers connected to outdoor cabling from ESD and induced RF transients. IC Role / Device Role / Timing Role: Bidirectional TVS mounted differential-line-to-ground, providing common-mode and differential-mode surge suppression.

| Automotive Body Control Modules | Renewable Energy Inverters |
Use Scenario: Safeguarding LIN bus nodes in door modules exposed to load dump and jump-start transients. IC Role / Device Role / Timing Role: Standoff-rated TVS on LIN line referenced to chassis ground, absorbing 12 V system-level surges. Use Value: 16 V VWM matches nominal 12 V automotive supply with margin; 150 °C rating sustains operation near engine compartments. | Use Scenario: Protecting PV string monitoring inputs in solar inverters from lightning-induced surges on long DC runs. IC Role / Device Role / Timing Role: High-energy TVS on analog sensor inputs, clamping transients before they reach isolation amplifiers or ADC front-ends. Use Value: 3000 W PPP rating handles multi-kA induced currents per IEC61000-4-5 Class 3 (12 Ω source), preserving measurement accuracy. |
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 | Limited to lower-energy transients; unsuitable for IEC61000-4-5 Class 3/4 or 3000 W surge events | Select when space-constrained layouts require smaller footprint and surge requirements are ≤600 W |
| 1.5KE16CA | 1500 W PPP, axial-leaded DO-15 package, higher clamping voltage (26.5 V) | Not surface-mount; requires through-hole assembly and lacks MIL-PRF-19500 upscreening path | Choose for legacy through-hole designs where reflow compatibility and high-reliability screening are not required |
Compared with SMBJ16CA and 1.5KE16CA, MDA3KP16CAE3 delivers double the surge power handling of the former and enables automated SMT assembly plus military-grade reliability screening unavailable in the latter-making it optimal for new industrial and automotive designs demanding robust, production-ready TVS protection.

FAQ
What is the clamping voltage of MDA3KP16CAE3 at its rated peak pulse current?
The MDA3KP16CAE3 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. Engineers use this parameter to verify that downstream components remain within absolute maximum ratings during transient suppression.
Is MDA3KP16CAE3 suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MDA3KP16CAE3 is qualified for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 2 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse power rating and 26.0 V clamping voltage ensure compliance under the 4 kV test level. However, at 12 Ω or 42 Ω source impedances, it supports only Classes 1–3, so system-level test configuration must be verified.
Does MDA3KP16CAE3 require moisture preconditioning before reflow soldering?
No, MDA3KP16CAE3 carries IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1 rating, meaning it has no floor life limitation and does not require dry packing or baking prior to reflow. This eliminates process steps and reduces risk of popcorn cracking during assembly-confirmed in the Mechanical and Packaging section of the RF01243 datasheet.
What does the "C" and "e3" suffix indicate in MDA3KP16CAE3?
In MDA3KP16CAE3, the "C" denotes bidirectional polarity (anti-parallel diode configuration), while "e3" specifies RoHS-compliant matte-tin plating per JEDEC J-STD-020. These suffixes are defined in the Part Nomenclature diagram on page 2 of RF01243 and confirm both functional symmetry and environmental compliance-critical for global industrial and automotive deployments.
Can MDA3KP16CAE3 replace unidirectional TVS devices like MDA3KP16AE3 in existing designs?
No-MDA3KP16CAE3 is strictly bidirectional and cannot substitute for unidirectional parts like MDA3KP16AE3 without circuit review. Its anti-parallel structure conducts in both directions, which may cause unintended current paths in DC-biased applications. Layout changes and functional validation are required before substitution; the datasheet explicitly separates "A" (unidirectional) and "C" (bidirectional) variants in all electrical tables and application guidance.
