Product details
Overview
MXDA3KP24CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability secondary lightning and ESD protection. It features a 24 V reverse standoff voltage (VWM), 26.7–29.5 V breakdown voltage (V(BR)), 38.9 V maximum clamping voltage at 77.2 A peak pulse current, and operates from –55 °C to +150 °C - deployed in industrial power supplies and telecom interface circuits.
For engineers reviewing the MXDA3KP24CA datasheet, MXDA3KP24CA pinout, MXDA3KP24CA application, or MXDA3KP24CA equivalent, key selection criteria include bidirectional polarity, 10/1000 µs surge rating, IEC61000-4-2/4-4/4-5 compliance, thermal derating above 25 °C, and RoHS-compliant matte-tin terminations per MIL-STD-750.
Technical Context
This TVS array uses silicon avalanche diode technology with void-free thermosetting epoxy packaging (UL94V-0). Its bidirectional construction enables symmetrical clamping on both polarities without external biasing, supporting ungrounded signal lines and AC-coupled interfaces.
It delivers 3000 W peak pulse power at 10/1000 µs waveform with <5 ns response time, fully surge-tested per lot, and includes 3σ screening on standby current (ID ≤ 2 µA @ VWM). Polarity is defined by odd-numbered pins as cathodes per device element.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - maximum continuous operating voltage before clamping begins; matches 24 V DC rails or ±17 V AC peaks |
| V(BR) min/max | 26.7–29.5 V - guaranteed avalanche onset range at 1 mA; ensures predictable turn-on margin over VWM |
| VC @ IPP | 38.9 V - clamping voltage at 77.2 A peak pulse; limits downstream voltage stress during transients |
| IPP | 77.2 A - maximum non-destructive 10/1000 µs surge current; defines protection capacity for IEC61000-4-5 Class 3 |
| ID @ VWM | ≤2 µA - leakage current at rated standoff; negligible power loss and no thermal runaway risk |
| TJ/TSTG | –55 to +150 °C - wide junction temperature range supports under-hood, outdoor, and industrial environments |
| Package | Surface-mount vertical array - compact footprint with defined pin 1 dot; compatible with automated reflow (260 °C, 10 s) |
Pinout & Package
MXDA3KP24CA is housed in a proprietary vertical surface-mount plastic package (Microsemi designation MDA series), UL94V-0 compliant, ~5 g weight, with tin-lead or matte-tin terminations solderable per MIL-STD-750 Method 2026. Pin 1 is marked by a dot on top of the body; odd-numbered pins are cathodes per TVS element.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (TVS1) | Reference terminal for first bidirectional TVS pair; connects to protected line or ground return path |
| Pin 2 | Anode (TVS1) | Complementary terminal to Pin 1; forms symmetrical clamping path across differential or single-ended signals |
| Pin 3 | Cathode (TVS2) | Second TVS element cathode; enables dual-line protection (e.g., RS-485 A/B or Ethernet pairs) |
| Pin 4 | Anode (TVS2) | Paired anode for TVS2; completes second independent bidirectional clamping path |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetric transient suppression on AC or floating lines without polarity assumptions or external bias |
| 3000 W peak pulse power | Withstands IEC61000-4-5 Class 3 surges (12 Ω source) and repetitive EFT bursts without degradation |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring lot traceability, wafer-level screening, and conformance inspection |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to assembly - reduces manufacturing overhead |
| RoHS-compliant (e3 marking) | Meets global environmental regulations without compromising surge performance or thermal robustness |
Applications
| Industrial Power Input Protection | Telecom Line Interface |
|---|---|
Use Scenario: 24 V DC input stage of programmable logic controllers exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Transient voltage suppressor array clamping surge energy before it reaches DC-DC converters and microcontrollers. Use Value: Limits voltage excursion to ≤38.9 V during 77.2 A transients, preventing latch-up or gate oxide damage in downstream ICs. | Use Scenario: RS-485 transceiver bus lines in factory automation networks subject to ESD and induced RF coupling. IC Role / Device Role / Timing Role: Bidirectional TVS pair protecting differential A/B lines against ±8 kV contact ESD (IEC61000-4-2) and fast transients. Use Value: Sub-5 ns response ensures clamping occurs before transceiver input stages experience overstress, preserving data integrity. |
| Secondary Lightning Protection | AC-DC Adapter Surge Suppression |
Use Scenario: Outdoor security camera power/data ports subjected to secondary lightning surges via PoE cabling (IEC61000-4-5, 42 Ω source). IC Role / Device Role / Timing Role: Primary front-end protector absorbing up to 3000 W (10/1000 µs) energy before downstream MOVs or GDTs activate. Use Value: Enables Class 4 compliance with 42 Ω source impedance while maintaining low clamping voltage for sensitive imaging sensors. | Use Scenario: Secondary-side rectifier output in medical-grade AC-DC adapters where leakage must remain <2 µA. IC Role / Device Role / Timing Role: Standby-current-optimized TVS suppressing switching spikes from synchronous rectifiers without loading regulation loop. Use Value: 2 µA max ID at 24 V VWM avoids measurable impact on no-load efficiency or output voltage accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | 600 W rating (vs. 3000 W); DO-214AA package; lower IPP (32.4 A) | Suitable for board-level ESD only; not rated for IEC61000-4-5 Class 3+ lightning | Select when space-constrained layouts require smaller footprint and surge demands are limited to IEC61000-4-2/4-4 |
| SMCJ24CA | 1500 W rating; DO-214AB package; IPP = 53.5 A; higher VC (38.9 V same) | Mid-tier surge capability; fits legacy SMC footprints but lacks MIL-PRF-19500 screening option | Choose for cost-sensitive industrial designs needing >600 W but not requiring full 3000 W or upscreening |
Compared with SMBJ24CA and SMCJ24CA, MXDA3KP24CA delivers 5× and 2× higher peak pulse power respectively, supports military-grade reliability screening, and maintains identical clamping voltage despite its higher rating - making it the only option qualified for Class 3/4 secondary lightning per IEC61000-4-5 with 12 Ω or 42 Ω source impedances.

FAQ
What is the polarity configuration of MXDA3KP24CA?
MXDA3KP24CA is a bidirectional TVS array, indicated by the "C" suffix in its part number. It contains two independent bidirectional elements - Pins 1/2 form one symmetrical clamping pair, and Pins 3/4 form another. Odd-numbered pins are cathodes per element, enabling protection on both voltage polarities without external biasing or orientation constraints.
Does MXDA3KP24CA meet IEC61000-4-5 Class 4 requirements?
Yes, MXDA3KP24CA meets IEC61000-4-5 Class 4 for secondary lightning protection with 42 Ω source impedance, and Class 3 with 12 Ω source impedance. Its 3000 W peak pulse power and 77.2 A IPP rating are validated per test conditions in the official Microsemi datasheet RF01243 Rev B, enabling use in outdoor telecom and industrial control equipment.
What is the maximum clamping voltage of MXDA3KP24CA and at what current is it specified?
The maximum clamping voltage (VC) of MXDA3KP24CA is 38.9 V, measured at its peak pulse current (IPP) of 77.2 A under 10/1000 µs waveform conditions. This value ensures protected circuitry remains below critical overvoltage thresholds during worst-case transients, as confirmed in the Electrical Characteristics table on page 3 of RF01243 Rev B.
Is MXDA3KP24CA RoHS compliant and how is compliance marked?
Yes, MXDA3KP24CA is RoHS compliant, indicated by the "e3" marking on the device body per Microsemi's part nomenclature guide. The "e3" suffix confirms annealed matte-tin plating and absence of lead, cadmium, mercury, hexavalent chromium, PBB, and PBDE - verified through material declarations and third-party testing per EU Directive 2011/65/EU.
Can MXDA3KP24CA be used in high-reliability programs requiring MIL-PRF-19500 screening?
Yes, MXDA3KP24CA supports optional MIL-PRF-19500 upscreening including wafer fabrication lot traceability, 3σ standby current screening, and conformance inspections. This capability is documented in the Features section of RF01243 Rev B and makes MXDA3KP24CA suitable for aerospace, defense, and critical infrastructure applications where component pedigree and long-term reliability are mandatory.
