Product details
Overview
MDA3KP17AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 17 V standoff voltage (VWM), 18.9–20.9 V breakdown range (V(BR)), and 27.6 V clamping voltage (VC) at 106.6 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 power supply input stages.
For engineers reviewing the MDA3KP17AE3 datasheet, MDA3KP17AE3 pinout, MDA3KP17AE3 application, or MDA3KP17AE3 equivalent, key selection criteria include its 17 V working voltage, 27.6 V clamping performance at 106.6 A, -55 °C to +150 °C operating junction temperature, RoHS-compliant e3 marking, and unidirectional polarity for DC-biased protection circuits.
Technical Context
The MDA3KP17AE3 operates as a silicon avalanche diode-based TVS array optimized for high-energy transient suppression in industrial and telecom power rails. Its unidirectional construction enables asymmetric clamping-low forward voltage (4.0 V @ 500 A) during overvoltage events while blocking reverse leakage below 2 µA at 17 V.
It delivers 3000 W peak pulse power at 10/1000 µs waveform with sub-100 ps response time, supports MIL-PRF-19500 upscreening options, and maintains moisture sensitivity level 1 per J-STD-020B-eliminating dry pack requirements for standard handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17 V maximum continuous reverse standoff voltage-sets minimum system operating voltage threshold before clamping activation |
| V(BR) min–max | 18.9–20.9 V breakdown range at 1 mA-defines guaranteed avalanche initiation window under test conditions |
| VC @ IPP | 27.6 V clamping voltage at 106.6 A peak pulse-determines maximum protected-circuit voltage excursion during surge |
| PPP | 3000 W peak pulse power rating at 10/1000 µs-quantifies single-event energy absorption capability |
| ID @ VWM | ≤2 µA standby leakage current at 17 V-ensures minimal power loss in quiescent DC systems |
| TJ / TSTG | -55 °C to +150 °C junction/storage temperature range-validates suitability for harsh-environment industrial deployments |
Pinout & Package
MDA3KP17AE3 uses a 3-pin SMC (DO-214AB) surface-mount package with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity defined by dot marking indicating Pin 1 (cathode). Odd-numbered pins are cathodes per device channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Anode-referenced clamping node-connects to protected line; requires external anode tie to ground or return rail |
| Pin 2 | Anode | Reference/return path-must be tied to system ground or low-impedance return for effective clamping |
| Pin 3 | Cathode | Second cathode terminal-enables dual-channel configuration or parallel current sharing in multi-line protection |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables robust protection against IEC61000-4-5 Class 4 surges (42 Ω source) without derating at 25 °C |
| Sub-100 ps response time | Clamps transients before downstream ICs experience damaging overvoltage-critical for fast-switching power supplies |
| MIL-PRF-19500 screening option | Supports high-reliability aerospace/defense applications via wafer lot traceability and 3σ ID screening |
| Moisture Level 1 rating | Eliminates bake-out and dry-pack logistics-reduces manufacturing cost and handling risk |
Applications
| Industrial Power Supply Input Protection | Telecom DC Feeder Line Protection |
|---|---|
Use Scenario: 24 V DC input stage of programmable logic controller (PLC) power module exposed to load dump and relay coil flyback.

Use Value: Achieves 54 V total clamping headroom with matched thermal derating-improving reliability vs. single-device solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17A | 600 W PPP rating, same VWM and VC, but lower IPP (33.3 A) and no MIL-PRF-19500 screening option | Suitable for consumer-grade surge protection where 3000 W energy absorption is not required | Select SMBJ17A only when system-level surge testing does not exceed IEC61000-4-5 Class 2 (1 kV) |
| SMCJ17A | 1500 W PPP rating, identical package and pinout, but 30% lower peak power handling than MDA3KP17AE3 | Applicable in mid-tier industrial equipment with moderate lightning exposure (Class 1–2) | Choose SMCJ17A if cost sensitivity outweighs need for full 3000 W margin in mission-critical infrastructure |
Compared with SMBJ17A and SMCJ17A, the MDA3KP17AE3 delivers double the pulse power margin of SMCJ17A and five times that of SMBJ17A-making it the only option qualified for Class 4 secondary lightning protection in high-reliability power systems.

FAQ
What is the clamping voltage of MDA3KP17AE3 at its rated peak pulse current?
The MDA3KP17AE3 has a maximum clamping voltage (VC) of 27.6 V at its rated peak pulse current (IPP) of 106.6 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 circuitry during worst-case surge events. The MDA3KP17AE3 maintains this clamping performance across its full operating temperature range.
Is MDA3KP17AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MDA3KP17AE3 is RoHS compliant-the 'e3' suffix explicitly denotes lead-free, RoHS-compliant termination per Microsemi's part numbering convention (Page 2, RF01243 Rev B). The device uses annealed matte-tin plating meeting MIL-STD-750 Method 2026 and carries no exemption codes. This compliance applies to both material content and finish, verified through factory-certified test reports for MDA3KP17AE3.
Can MDA3KP17AE3 be used for bidirectional transient protection?
No, MDA3KP17AE3 is unidirectional only. Its part number lacks the 'C' suffix (e.g., MDA3KP17CE3) required for bidirectional variants. The device clamps positive transients relative to its anode connection and blocks reverse current-making it unsuitable for AC-coupled or bipolar signal lines. For bidirectional protection, MDA3KP17CE3 must be selected instead, as confirmed in the "Part Nomenclature" section on Page 2 of RF01243.
What is the maximum operating temperature range for MDA3KP17AE3?
The MDA3KP17AE3 supports a junction and storage temperature range of -55 °C to +150 °C, as specified in the Maximum Ratings table (Page 2, RF01243 Rev B). This wide range enables deployment in under-hood automotive modules, outdoor telecom cabinets, and industrial motor drives where ambient temperatures exceed 100 °C. Derating begins above 25 °C per Figure 3, with 50% power capability retained at +125 °C for MDA3KP17AE3.
Does MDA3KP17AE3 require special handling or moisture baking prior to reflow?
No, MDA3KP17AE3 does not require moisture baking or dry pack storage. It is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B (Page 2, RF01243 Rev B), meaning it may be stored indefinitely at ≤30 °C/60% RH and placed directly into standard reflow profiles-including lead-free peak temperatures up to 260 °C for 10 seconds-without preconditioning. This eliminates process steps and yield loss associated with MSL 2+ components like MDA3KP17AE3.
