Product details
Overview
MXDA3KP13CA 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 13 V reverse standoff voltage (VWM), 14.4–15.9 V breakdown voltage (V(BR)), 21.5 V maximum clamping voltage at 139.4 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MXDA3KP13CA datasheet, MXDA3KP13CA pinout, MXDA3KP13CA application, or MXDA3KP13CA 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 e3 marking, and 100 ps response time - critical for telecom surge interfaces, industrial I/O protection, and automotive body electronics.
Technical Context
The MXDA3KP13CA is a silicon avalanche diode-based TVS array optimized for fast-clamping transient suppression in bidirectional signal paths. Its design integrates dual-anode/dual-cathode symmetry to ensure symmetrical clamping in both polarities, with guaranteed breakdown at ≥14.4 V and ≤15.9 V under 1 mA test current.
It meets IEC61000-4-5 secondary lightning requirements across multiple source impedances (42 Ω, 12 Ω, 2 Ω), supports ESD per IEC61000-4-2 (±30 kV air, ±30 kV contact), and EFT per IEC61000-4-4 (40 A, 5/50 ns). The device is surge-tested per 10/1000 μs waveform and rated for 3000 W peak pulse power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous operating voltage before clamping begins; matches 12 V nominal bus systems with margin. |
| V(BR) min/max | 14.4–15.9 V @ 1 mA - Ensures reliable turn-on above system peak voltage while avoiding false triggering. |
| VC @ IPP | 21.5 V @ 139.4 A - Clamps transients to safe levels for downstream 24 V logic or analog circuitry. |
| PPP | 3000 W @ 10/1000 μs - Handles high-energy surges from inductive switching or lightning coupling. |
| TJ range | –55 °C to +150 °C - Supports operation in under-hood automotive or industrial control cabinet environments. |
| Response time | <100 ps - Faster than most microcontrollers' interrupt latency, enabling pre-damage suppression. |
| RoHS | e3 marking - Lead-free matte-tin plating compliant with IPC/JEDEC J-STD-020B Level 1 moisture sensitivity. |
Pinout & Package
MXDA3KP13CA uses a DO-214AB (SMC) surface-mount package with two terminals: Pin 1 (cathode for one diode) and Pin 2 (anode for same diode); bidirectional configuration means both terminals serve symmetrically as anode/cathode pairs. Package dimensions: 21.03–22.05 mm length × 6.86–7.87 mm width × 8.64–9.65 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of D1 / Anode of D2 | Shared terminal enabling bidirectional clamping; connects to protected line (e.g., RS-485 A/B). |
| Pin 2 | Anode of D1 / Cathode of D2 | Shared terminal completing symmetrical path; typically tied to ground or common reference plane. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection of AC-coupled or differential lines without polarity concerns. |
| 3000 W peak pulse rating | Withstands repeated 10/1000 μs surges up to 139.4 A - sufficient for IEC61000-4-5 Level 4 with 42 Ω source. |
| 100 ps response time | Clamps transients before propagation into sensitive IC inputs, reducing need for additional RC filtering. |
| MIL-PRF-19500 screening option | Supports high-reliability aerospace/defense programs requiring lot traceability and 3σ ID screening. |
| UL94V-0 epoxy case | Self-extinguishing thermoset housing prevents flame propagation in enclosed industrial enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | 600 W PPP rating, 13 V VWM, DO-214AA package; lower surge capacity and smaller thermal mass. | Suitable for consumer-grade ESD-only protection; insufficient for IEC61000-4-5 Class 3+ or repetitive industrial surges. | Select MXDA3KP13CA when 3000 W energy absorption and MIL-PRF-19500 screening are required. |
| SMCJ13CA | 1500 W PPP rating, identical DO-214AB package and 13 V VWM; half the peak pulse power of MXDA3KP13CA. | Valid for Class 2 lightning per 42 Ω source but fails Class 3/4 testing; lacks high-reliability screening options. | Choose MXDA3KP13CA for mission-critical infrastructure where single-event robustness and lot traceability matter. |
Compared with SMBJ13CA and SMCJ13CA, MXDA3KP13CA delivers double the surge energy handling of SMCJ13CA and five times that of SMBJ13CA, with verified performance across all IEC61000-4-5 Class 1–4 configurations and optional military-grade screening - making it the only choice for high-availability industrial and transportation systems.

FAQ
What is the clamping voltage of MXDA3KP13CA at its rated peak pulse current?
The MXDA3KP13CA has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPP) of 139.4 A under 10/1000 μs waveform conditions. This value is measured across the device terminals during standardized surge testing and ensures downstream 24 V-rated ICs remain within safe operating limits during transient events. The MXDA3KP13CA maintains this clamping performance across its full operating temperature range.
Is MXDA3KP13CA unidirectional or bidirectional, and how does that affect circuit placement?
MXDA3KP13CA is a bidirectional TVS, indicated by the "C" suffix in its part number. It provides symmetrical clamping for both positive and negative transients, eliminating polarity concerns during layout. This allows direct placement across differential lines like RS-485 or CAN without orientation checks. Unlike unidirectional variants, MXDA3KP13CA requires no DC biasing and functions identically regardless of signal swing direction.
Does MXDA3KP13CA meet IEC61000-4-5 Class 4 requirements, and under what source impedance?
Yes, MXDA3KP13CA meets IEC61000-4-5 Class 4 requirements with a 42 Ω source impedance, as confirmed in the official Microsemi documentation (RF01243, Rev B, Page 1). It also satisfies Class 1–3 with 12 Ω and Class 2–4 with 2 Ω source impedances. The MXDA3KP13CA's 3000 W rating and 21.5 V clamping enable compliance across these configurations without derating or parallel devices.
What is the package type and moisture sensitivity level of MXDA3KP13CA?
MXDA3KP13CA uses the DO-214AB (SMC) surface-mount package with void-free UL94V-0 epoxy body and matte-tin (e3) plating. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1, meaning no dry pack or baking is required prior to reflow soldering. The MXDA3KP13CA's 5 g weight and 22 mm length support automated pick-and-place in high-volume manufacturing.
Can MXDA3KP13CA be used for ESD protection per IEC61000-4-2, and what is its tested rating?
Yes, MXDA3KP13CA is qualified for ESD protection per IEC61000-4-2, with documented capability to withstand ±30 kV contact discharge and ±30 kV air discharge. Its <100 ps response time ensures clamping occurs before ESD energy couples into sensitive nodes. The MXDA3KP13CA's low clamping voltage and high surge tolerance make it effective for both system-level ESD and secondary lightning events - unlike standard ESD diodes limited to <100 W.
