Product details
Overview
MDA3KP17CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in industrial and aerospace systems. It features a 17 V reverse standoff voltage (VWM), 18.9–20.9 V breakdown voltage (V(BR)), 27.6 V maximum clamping voltage at 106.6 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MDA3KP17CA datasheet, MDA3KP17CA pinout, MDA3KP17CA application, or MDA3KP17CA equivalent, this device supports IEC61000-4-5 secondary lightning protection (Class 1–4 with 42 Ω source), ESD/EFT immunity per IEC61000-4-2/4-4, and inductive switching transient suppression in power supply and signal line interfaces.
Technical Context
The MDA3KP17CA is a surface-mount, bidirectional TVS diode array built using silicon avalanche technology. Its clamping response time is under 5 ns, enabling effective suppression of fast transients including ESD (±30 kV contact), EFT (±4 kV), and 10/1000 μs lightning surges up to 3000 W.
It complies with MIL-PRF-19500 screening options for high-reliability applications and features wafer-level traceability, 100% surge testing, and IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - eliminating dry pack requirements.
Key Specifications

|---|---|
| VWM | 17 V - Maximum continuous DC or peak AC operating voltage before clamping initiates |
| V(BR) min/max | 18.9–20.9 V @ 1 mA - Ensures reliable avalanche conduction onset within defined tolerance band |
| VC @ IPP | 27.6 V @ 106.6 A - Clamping voltage during 10/1000 μs surge limits downstream component stress |
| PPP | 3000 W @ 10/1000 μs - Peak power handling capacity validated per Figure 1 waveform |
| ID @ VWM | 2 μA max - Ultra-low leakage preserves signal integrity and minimizes standby power loss |
| TJ range | –55 °C to +150 °C - Enables deployment in extended-temperature environments including avionics and motor drives |
Pinout & Package
MDA3KP17CA uses a 3-pin SMC (DO-214AB) surface-mount package with cathode-defined polarity: Pin 1 = Cathode, Pin 2 = Anode/Cathode common (center tab), Pin 3 = Cathode. The molded thermosetting epoxy case meets UL94V-0; terminals are matte-tin plated per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Primary current sink terminal for bidirectional clamping path; marked by dot on package top |
| Pin 2 | Common Anode/Cathode | Center tab connection enabling symmetrical bidirectional conduction between Pins 1 and 3 |
| Pin 3 | Cathode | Second cathode terminal completing the bidirectional TVS structure; electrically identical to Pin 1 |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17CA | 600 W PPP rating, same VWM and bidirectional configuration, SMC package | Limited to Class 2 IEC61000-4-5; insufficient for Class 4 lightning with 42 Ω source | Select when system-level surge energy is ≤600 W and space-constrained layout favors identical footprint |
| SMCJ17CA | 1500 W PPP rating, same VWM and bidirectional construction, SMC package | Meets Class 3 IEC61000-4-5 but fails Class 4 validation at 42 Ω source impedance | Choose where cost optimization is prioritized and full 3000 W capability is not required by safety certification |
Compared with SMBJ17CA and SMCJ17CA, the MDA3KP17CA delivers double the surge power handling of SMCJ17CA and five times that of SMBJ17CA - enabling single-device compliance with stringent Class 4 secondary lightning standards without parallel staging.

FAQ
What is the clamping voltage of the MDA3KP17CA at its rated peak pulse current?
The MDA3KP17CA 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 test setup and guarantees predictable voltage limiting during surge events. The MDA3KP17CA maintains this clamping performance across its full operating temperature range.
Is the MDA3KP17CA RoHS compliant?
Yes, the MDA3KP17CA is RoHS compliant, indicated by the "e3" suffix in its full marking per page 2 of RF01243 Rev B. The device uses annealed matte-tin plating and void-free UL94V-0 epoxy packaging, meeting EU Directive 2011/65/EU requirements without exemptions. The MDA3KP17CA is suitable for environmentally regulated industrial and medical end equipment.
How does the MDA3KP17CA differ from unidirectional variants like MDA3KP17A?
The MDA3KP17CA is bidirectional, providing symmetrical clamping for AC signals or differential lines, whereas MDA3KP17A is unidirectional and only clamps in reverse bias. The MDA3KP17CA's breakdown voltage range (18.9–20.9 V) applies equally in both polarities, enabling use in telecom transformers and motor phase-leg protection where polarity reversal occurs. The MDA3KP17CA shares identical package, thermal specs, and surge ratings with MDA3KP17A.
Can the MDA3KP17CA be used for IEC61000-4-5 Class 4 lightning protection?
Yes, the MDA3KP17CA is 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 RF01243 Rev B. Its 3000 W peak pulse power rating and 27.6 V clamping voltage ensure compliance without additional staging. The MDA3KP17CA must be mounted with low-inductance layout practices to preserve sub-5 ns response.
What is the maximum operating temperature for the MDA3KP17CA?
The MDA3KP17CA supports a junction temperature range of –55 °C to +150 °C, verified per Absolute Maximum Ratings table on page 2 of RF01243 Rev B. This enables deployment in under-hood automotive modules, downhole oilfield tools, and enclosed medical power supplies where ambient temperatures exceed 100 °C. The MDA3KP17CA's derating curve (Figure 3) shows 85% power retention at 100 °C ambient.
