Product details
Overview
MXLDA3KP24CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in industrial and telecom power rails. It features a 24 V standoff voltage (VWM), 26.7–29.5 V breakdown range (V(BR)), 38.9 V maximum clamping voltage at 77.2 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MXLDA3KP24CA datasheet, MXLDA3KP24CA pinout, MXLDA3KP24CA application, or MXLDA3KP24CA equivalent, key selection criteria include IEC61000-4-5 secondary lightning compliance (Class 1–4 with 42 Ω source), ESD/EFT immunity per IEC61000-4-2/4-4, 100 ps response time, and RoHS-compliant void-free epoxy packaging.
Technical Context
The MXLDA3KP24CA is a surface-mount bidirectional TVS diode array optimized for fast transient suppression on DC power lines and signal interfaces subject to lightning-induced surges or switching transients. Its design integrates low clamping voltage (38.9 V @ 77.2 A) with high peak pulse power handling (3000 W @ 10/1000 µs) and sub-100 ps response time.
It complies with IEC61000-4-5 for secondary lightning protection under multiple source impedances (42 Ω, 12 Ω, 2 Ω), supports MIL-PRF-19500 upscreening options, and maintains <2 µA standby current at 24 V standoff-enabling robust protection without system leakage penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - Maximum continuous operating voltage before clamping begins |
| V(BR) min/max | 26.7–29.5 V - Breakdown initiates within this range at 1 mA, ensuring predictable turn-on margin |
| VC @ IPP | 38.9 V - Clamping voltage seen by protected circuit during 77.2 A 10/1000 µs surge |
| IPP | 77.2 A - Peak surge current capability at rated clamping voltage |
| PPP | 3000 W - Peak pulse power dissipation capacity under standard 10/1000 µs waveform |
| TJ range | –55 °C to +150 °C - Full operational junction temperature range for harsh-environment deployment |
| ID @ VWM | ≤2 µA - Ultra-low leakage ensures minimal impact on upstream power regulation or sensing circuits |
Pinout & Package
MXLDA3KP24CA uses a 2-pin DO-214AB (SMC) surface-mount package with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity defined by dot marking indicating Pin 1 (cathode for unidirectional variants; symmetric for bidirectional). Pin 1 and Pin 2 are interchangeable in bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | Interchangeable terminal; no fixed polarity-functions as either anode or cathode depending on transient polarity |
| Pin 2 | Anode/Cathode (bidirectional) | Interchangeable terminal; forms symmetrical clamping path with Pin 1 for AC or dual-polarity DC lines |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines or floating DC buses without polarity constraints |
| IEC61000-4-5 Class 1–4 compliance | Validated for secondary lightning protection with 42 Ω, 12 Ω, and 2 Ω source impedances |
| RoHS-compliant e3 marking | Meets lead-free assembly requirements with annealed matte-tin termination finish |
| Moisture sensitivity Level 1 | No dry pack or baking required prior to reflow-reduces manufacturing overhead |
| 3σ lot norm screening on ID | Ensures consistent low-leakage performance across production lots for critical power-rail applications |

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 PPP rating, 38.9 V VC @ 17.1 A IPP - lower surge capacity than MXLDA3KP24CA's 3000 W/77.2 A | Suitable for lower-energy ESD/EFT only; not rated for IEC61000-4-5 Class 4 lightning with 42 Ω source | Select SMBJ24CA only when surge threat level is limited to IEC61000-4-2/4-4 and PCB space is constrained. |
| 1.5KE24CA | 3000 W PPP but axial-leaded DO-201 package - incompatible with automated SMT assembly and higher thermal resistance | Requires through-hole rework or adapter; lacks moisture Level 1 rating and RoHS e3 marking | Choose 1.5KE24CA only for legacy through-hole designs where reflow compatibility is not required. |
Compared with SMBJ24CA and 1.5KE24CA, MXLDA3KP24CA delivers full 3000 W surge immunity in a RoHS-compliant, SMT-ready SMC package with validated IEC61000-4-5 Class 4 compliance-making it the preferred choice for new industrial and telecom designs requiring high-reliability automated assembly.

FAQ
What is the clamping voltage of MXLDA3KP24CA at its rated peak pulse current?
The MXLDA3KP24CA has a maximum clamping voltage (VC) of 38.9 V at its rated peak pulse current (IPP) of 77.2 A under 10/1000 µs waveform conditions. This value is guaranteed across the full operating temperature range and ensures protected circuits remain below critical overvoltage thresholds during surge events.
Is MXLDA3KP24CA compliant with IEC61000-4-5 for secondary lightning protection?
Yes, MXLDA3KP24CA is validated for IEC61000-4-5 secondary lightning protection across Class 1–4 with 42 Ω source impedance, and Class 1–3 with 12 Ω source impedance. Its 3000 W peak pulse power rating and low clamping voltage enable reliable performance under standardized lightning surge waveforms.
Does MXLDA3KP24CA require dry packing or baking before reflow soldering?
No, MXLDA3KP24CA is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it does not require dry packing or pre-reflow baking. This simplifies manufacturing flow and eliminates moisture-related popcorning risks during standard lead-free reflow profiles.
What is the polarity configuration of MXLDA3KP24CA?
MXLDA3KP24CA is a bidirectional TVS device, indicated by the "C" suffix in its part number. Its terminals are symmetrical-Pin 1 and Pin 2 function interchangeably as anode/cathode depending on transient polarity-making it ideal for AC lines or floating DC rails without orientation constraints.
Can MXLDA3KP24CA be used in automotive applications such as body control modules?
Yes, MXLDA3KP24CA is suitable for automotive body control modules operating from 24 V systems. Its –55 °C to +150 °C junction temperature range, 3000 W surge capability, and fast ≤100 ps response meet requirements for load dump and ISO 7637-2 transient suppression when placed at board entry points.
