Product details
Overview
MDA3KP22CAE3 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 22 V reverse standoff voltage (VWM), 24.4–26.9 V breakdown voltage (V(BR)), 35.5 V maximum clamping voltage at 84.4 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MDA3KP22CAE3 datasheet, MDA3KP22CAE3 pinout, MDA3KP22CAE3 application, or MDA3KP22CAE3 equivalent, key selection criteria include IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω/2 Ω source impedances, bidirectional polarity, RoHS-compliant matte-tin plating, and 100 ps response time - critical for telecom power rails, industrial I/O ports, and automotive body control modules.
Technical Context
The MDA3KP22CAE3 implements a silicon avalanche diode structure optimized for fast transient suppression with sub-100 ps turn-on. Its bidirectional configuration enables symmetrical clamping across both polarities without external circuitry, supporting AC-coupled signal lines and ungrounded bus protection.
It meets MIL-PRF-19500 screening options for high-reliability applications and delivers 3000 W peak pulse power at 10/1000 μs waveform while maintaining <2 μA standby current at 22 V and full derating above 25 °C per Figure 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22 V - Maximum continuous operating voltage before clamping begins; matches 24 V nominal DC systems with margin. |
| V(BR) min/max | 24.4 V / 26.9 V - Confirmed avalanche onset range at 1 mA; ensures predictable turn-on across temperature and lot variation. |
| VC @ IPP | 35.5 V @ 84.4 A - Clamping voltage during 10/1000 μs surge; limits downstream IC stress to safe levels under IEC61000-4-5 testing. |
| PPP | 3000 W - Peak pulse power handling capability; supports repeated surges up to 0.05% duty cycle without degradation. |
| TJ range | –55 °C to +150 °C - Extended junction temperature rating enables use in under-hood automotive or industrial enclosures. |
| Response time | <100 ps - Near-instantaneous avalanche response; protects against ESD per IEC61000-4-2 Level 4 (15 kV contact). |
| RoHS | e3 - Matte-tin plating compliant with EU RoHS Directive 2011/65/EU; no lead or hazardous substances. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22CA | 600 W PPP rating, SMB package (smaller footprint), 37.1 V VC @ 33.5 A IPP. | Limited to lower-energy surges; unsuitable for IEC61000-4-5 Class 3/4 or repeated 3000 W events. | Select when space-constrained and surge energy is ≤600 W; verify thermal dissipation in high-duty-cycle environments. |
| 1.5KE22CA | Through-hole DO-201 package, 1500 W PPP, 35.5 V VC @ 42.2 A IPP, higher thermal mass but larger board area. | Not surface-mount; incompatible with automated SMT assembly; better low-frequency surge endurance but slower response than MDA3KP22CAE3. | Choose for legacy through-hole designs or where manual rework access is prioritized over density and speed. |
Compared with SMBJ22CA and 1.5KE22CA, MDA3KP22CAE3 delivers 5× higher peak power handling than SMBJ22CA and 2× higher than 1.5KE22CA in an SMT package, enabling robust Class 4 lightning protection without layout redesign or thermal derating penalties.

FAQ
What is the clamping voltage of MDA3KP22CAE3 at its rated peak pulse current?
The MDA3KP22CAE3 has a maximum clamping voltage (VC) of 35.5 V at its rated peak pulse current (IPP) of 84.4 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 circuits during worst-case surge events. The MDA3KP22CAE3 maintains this clamping performance across its full operating temperature range.
Is MDA3KP22CAE3 suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MDA3KP22CAE3 is validated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. It also supports Class 4 with 12 Ω and 2 Ω sources for specific voltage ranges - though MDA3KP22CAE3 falls within the MDA3KP6.0CA–MDA3KP18A group for 2 Ω/Class 4, its 22 V rating qualifies it for 42 Ω/Class 4 and 12 Ω/Class 3. The MDA3KP22CAE3 datasheet explicitly lists Class 1–4 coverage for 42 Ω and 12 Ω configurations.
What does the "C" and "E3" suffix mean in MDA3KP22CAE3?
In MDA3KP22CAE3, the "C" suffix denotes bidirectional polarity, meaning the device provides symmetrical clamping for both positive and negative transients across its terminals. The "E3" suffix indicates RoHS-compliant matte-tin plating per JEDEC J-STD-020B, with no lead or restricted substances. This marking follows Microsemi's nomenclature on page 2 of RF01243 and confirms full compliance with EU Directive 2011/65/EU. The MDA3KP22CAE3 is fully compatible with lead-free reflow profiles.
Does MDA3KP22CAE3 require moisture preconditioning before reflow soldering?
No, MDA3KP22CAE3 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions without dry packing or baking. The device's void-free epoxy body and plating ensure no moisture absorption risk during standard SMT reflow. This eliminates pre-bake steps and reduces process complexity - a verified specification stated in the Features section of the RF01243 datasheet. The MDA3KP22CAE3 is ready for immediate placement and reflow.
How does the pin configuration of MDA3KP22CAE3 support bidirectional protection?
MDA3KP22CAE3 uses a three-terminal DO-214AB package where Pin 1 and Pin 3 serve as outer terminals and Pin 2 is the common center tap. This configuration forms two back-to-back avalanche diodes: Pin 1→Pin 2 and Pin 2→Pin 3. During a positive transient on Pin 1, current flows through the first diode to Pin 2; during a negative transient, current flows from Pin 2 through the second diode to Pin 3 - enabling true bidirectional clamping without external components. The MDA3KP22CAE3 pinout is defined in the Mechanical and Packaging section of RF01243.
