Product details
Overview
MXDA3KP22CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-218AB package, designed for secondary lightning protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD suppression per IEC61000-4-2, and EFT protection per IEC61000-4-4. It features a 22 V reverse standoff voltage (VWM), 24.4–26.9 V breakdown voltage (V(BR)), and 35.5 V maximum clamping voltage (VC) at 84.4 A peak pulse current (IPP).
For engineers reviewing the MXDA3KP22CA datasheet, MXDA3KP22CA pinout, MXDA3KP22CA application, or MXDA3KP22CA equivalent, this device serves as a high-reliability, RoHS-compliant TVS for industrial power supplies, telecom line cards, and automotive body control modules requiring robust surge immunity with ≤5 ns response time and full MIL-PRF-19500 upscreening capability.
Technical Context
The MXDA3KP22CA is a bidirectional TVS diode array optimized for fast transient suppression across AC-coupled or floating signal/power lines. Its symmetrical clamping behavior ensures equal positive/negative surge handling, with <5 ns response time enabling protection against ESD events and fast-rising inductive switching transients.
It operates over –55 °C to +150 °C junction temperature, supports 260 °C soldering per MIL-STD-750 Method 2026, and delivers 3000 W peak pulse power at 10/1000 µs waveform - validated per Figure 1 of RF01243 Rev B - with full lot traceability and 3σ screening on standby current (ID).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22 V - Maximum continuous operating voltage before clamping begins; matches 24 V nominal DC bus systems. |
| V(BR) min/max | 24.4–26.9 V - Confirmed breakdown range at 1 mA; ensures reliable turn-on margin above VWM. |
| VC @ IPP | 35.5 V - Clamping voltage at 84.4 A peak pulse; limits downstream voltage stress during 10/1000 µs surges. |
| IPP | 84.4 A - Peak impulse current supported at rated clamping voltage; derived from 3000 W / 35.5 V calculation. |
| ID @ VWM | 2 µA - Standby leakage at 22 V; negligible power loss in always-on protection circuits. |
| Response time | <5 ns - Bidirectional turn-on delay; sufficient for IEC61000-4-2 Level 4 (15 kV contact) and EFT bursts. |
| TJ/TSTG | –55 to +150 °C - Extended thermal range enables under-hood automotive and industrial outdoor deployment. |
Pinout & Package
MXDA3KP22CA uses a 2-pin DO-218AB surface-mount package (case outline per Page 6 of RF01243 Rev B), with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity defined by dot marking indicating Pin 1 (anode/cathode pair center point). Odd-numbered pins are cathodes per series configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of first TVS element | Connects to protected line; forms symmetrical clamp path with Pin 2 in bidirectional operation. |
| Pin 2 | Cathode of first TVS element | Reference node for clamping; tied to common ground or return path in differential or single-ended layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables AC-line and floating-bus protection without polarity constraints; eliminates need for dual unidirectional devices. |
| 3000 W peak pulse rating | Sustains 10/1000 µs surges up to 84.4 A at 35.5 V clamping - exceeds IEC61000-4-5 Class 4 requirements with 42 Ω source. |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring wafer/lot traceability, 3σ ID screening, and conformance inspection per Micronote 129. |
| Moisture sensitivity Level 1 | No dry pack required per IPC/JEDEC J-STD-020B; simplifies SMT handling and eliminates bake-out steps pre-reflow. |

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 rating, 33.2 V VC @ 17.1 A IPP, DO-214AA package | Limited to lower-energy transients; unsuitable for IEC61000-4-5 Class 4 with 42 Ω source | Select when board space is constrained and surge energy remains below 600 W. |
| SMCJ22CA | 1500 W rating, 35.5 V VC @ 42.2 A IPP, DO-214AB package | Half the peak power handling of MXDA3KP22CA; requires derating above 85 °C per Figure 3 | Choose for cost-sensitive designs where 1500 W meets IEC61000-4-5 Class 2/3 requirements. |

FAQ
What is the clamping voltage of MXDA3KP22CA at its rated peak pulse current?
The MXDA3KP22CA has a maximum clamping voltage (VC) of 35.5 V at 84.4 A peak pulse current (IPP), measured under 10/1000 µs waveform conditions per Figure 2 of RF01243 Rev B. This value ensures protected circuitry remains below critical voltage thresholds during standardized surge events, including IEC61000-4-5 testing with 42 Ω source impedance.
Is MXDA3KP22CA RoHS compliant?
Yes, MXDA3KP22CA is RoHS compliant, indicated by the "e3" suffix in its full part marking per Page 2 of RF01243 Rev B. The device uses annealed matte-tin or tin-lead plating and void-free UL94V-0 epoxy packaging, meeting EU Directive 2011/65/EU requirements without exemptions.
Does MXDA3KP22CA support MIL-PRF-19500 screening?
Yes, MXDA3KP22CA offers optional MIL-PRF-19500 upscreening with wafer/lot traceability, 3σ screening on standby current (ID), and conformance inspections. Details are provided in Micronote 129, and screening must be specified at order entry - standard units ship without upscreening unless requested.
What is the thermal operating range of MXDA3KP22CA?
MXDA3KP22CA operates across a junction and storage temperature range of –55 °C to +150 °C, validated per Maximum Ratings Table on Page 2 of RF01243 Rev B. This enables deployment in under-hood automotive environments, outdoor telecom enclosures, and industrial motor drives without thermal derating below 25 °C.
How does the bidirectional design of MXDA3KP22CA affect its PCB layout?
The bidirectional design of MXDA3KP22CA allows placement across AC-coupled or floating nodes without polarity concerns - e.g., across RS-485 differential pairs or transformer-coupled Ethernet lines. Pin 1 is marked by a dot and serves as the anode/cathode center point; layout must maintain symmetric trace lengths to both pins to preserve balanced clamping performance.
