Product details
Overview
MXDA3KP11CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in power and signal lines. It features a 11 V reverse standoff voltage (VWM), 12.2–13.5 V breakdown voltage (V(BR)), 18.2 V maximum clamping voltage at 164.8 A peak pulse current, and operates from –55 °C to +150 °C. It protects against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5) in telecom and industrial power interfaces.
For engineers reviewing the MXDA3KP11CA datasheet, MXDA3KP11CA pinout, MXDA3KP11CA application, or MXDA3KP11CA equivalent, key selection criteria include bidirectional polarity, 18.2 V clamping at 164.8 A, 11 V working voltage, MIL-PRF-19500 upscreening eligibility, and surface-mount DO-214AB package compatibility with IEC-compliant surge waveforms.
Technical Context
The MXDA3KP11CA implements a silicon avalanche diode structure optimized for sub-5 ns response time and low clamping ratio (VC/V(BR) ≈ 1.42). Its bidirectional configuration enables symmetrical clamping on AC or differential signal lines without polarity constraints.
It is rated for 3000 W peak pulse power at 10/1000 µs waveform, supports 1000 V/m surge immunity per IEC61000-4-5 with 42 Ω source impedance (Class 1–4), and maintains <2 µA standby current at 11 V, ensuring minimal leakage in always-on monitoring circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11 V - Maximum continuous operating voltage before clamping begins; matches 12 V nominal DC rails with margin. |
| V(BR) min/max | 12.2–13.5 V - Confirmed avalanche onset range at 1 mA; ensures predictable turn-on across temperature and lot variation. |
| VC @ IPP | 18.2 V at 164.8 A - Clamping voltage under full 3000 W surge; limits downstream IC stress to safe levels. |
| PPP | 3000 W @ 10/1000 µs - Peak power handling capability validated per Figure 1; suitable for lightning-induced transients. |
| ID @ VWM | 5 µA - Standby leakage at rated standoff; negligible loading on high-impedance sensor or control inputs. |
| TJ/TSTG | –55 to +150 °C - Extended thermal range enables use in automotive engine compartments and industrial motor drives. |
Pinout & Package
MXDA3KP11CA is housed in a surface-mount DO-214AB (SMC) package with two terminals: Pin 1 (cathode of first TVS element) and Pin 2 (anode of first TVS element), configured as a bidirectional pair. Polarity is marked by a dot on the package top indicating Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Bidirectional Anode-Cathode Pair) | Common connection point for both avalanche junctions; defines symmetry axis for bidirectional clamping. |
| Pin 2 | Anode (Bidirectional Anode-Cathode Pair) | Completes the dual-junction path; enables equal positive/negative voltage clamping between terminals. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables single-device protection of AC lines, RS-485 buses, or Ethernet pairs without external polarity management. |
| 3000 W peak pulse rating | Withstands IEC61000-4-5 42 Ω Class 4 surges (4 kV) without degradation or parametric shift. |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring wafer lot traceability, 3σ ID screening, and conformance inspection. |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing cost and process risk. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package (smaller footprint). | Limited to Class 2 IEC61000-4-5 (1 kV); insufficient for 4 kV telecom or industrial lightning zones. | Select when board space is constrained and surge threat level is ≤2 kV. |
| SMCJ11CA | 1500 W PPP rating, identical DO-214AB package, same VWM and clamping voltage tolerance. | Half the energy handling of MXDA3KP11CA; requires derating above 85 °C ambient per Figure 3. | Choose for cost-sensitive designs where 3000 W headroom is not required and thermal margin exists. |
Compared with SMBJ11CA and SMCJ11CA, MXDA3KP11CA delivers 2× and 2× higher peak pulse power respectively, enabling robust Class 4 lightning protection without parallel devices or layout redesign-critical for infrastructure-grade reliability.

FAQ
What is the clamping voltage of MXDA3KP11CA at its rated peak pulse current?
The MXDA3KP11CA has a maximum clamping voltage (VC) of 18.2 V at its rated peak pulse current (IPP) of 164.8 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 circuitry during worst-case surge events. The MXDA3KP11CA maintains this clamping performance across its full operating temperature range.
Is MXDA3KP11CA unidirectional or bidirectional, and how is polarity marked?
MXDA3KP11CA is a bidirectional transient voltage suppressor, indicated by the "C" suffix in its part number. Polarity is defined by a dot on the top surface of the DO-214AB package, marking Pin 1 as the cathode terminal of the internal dual-junction structure. This allows symmetrical clamping for both positive and negative transients without external orientation constraints.
Does MXDA3KP11CA meet IEC61000-4-5 for secondary lightning protection?
Yes, MXDA3KP11CA is certified for secondary lightning protection per IEC61000-4-5 across multiple classes: Class 1–4 with 42 Ω source impedance, Class 1–3 with 12 Ω, and Class 2 with 2 Ω. Its 3000 W peak pulse rating and 18.2 V clamping voltage ensure compliance with the 4 kV test level in Class 4 configurations, as documented in the Applications section of the RF01243 datasheet.
What is the maximum operating temperature range for MXDA3KP11CA?
The MXDA3KP11CA is rated for junction and storage temperatures from –55 °C to +150 °C. This extended range supports deployment in under-hood automotive systems, industrial variable-frequency drives, and outdoor telecom enclosures. Derating of peak pulse power begins above 25 °C, as shown in Figure 3 of the RF01243 datasheet, with 50% power capability retained at +125 °C.
Can MXDA3KP11CA be used for ESD protection per IEC61000-4-2?
Yes, MXDA3KP11CA is explicitly qualified for ESD protection per IEC61000-4-2 due to its <5 ns response time and low clamping voltage. It suppresses ±8 kV contact and ±15 kV air discharge events by limiting transient voltage to ≤18.2 V at peak currents exceeding 100 A. Its fast avalanche response prevents damage to sensitive interface ICs such as USB transceivers or CAN controllers when placed at board-level entry points.
