Product details
Overview
MXLDA3KP7.0CA 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 7.0 V reverse standoff voltage (VWM), 7.78–8.6 V breakdown voltage (V(BR)), 12.0 V maximum clamping voltage (VC) at 250 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MXLDA3KP7.0CA datasheet, MXLDA3KP7.0CA pinout, MXLDA3KP7.0CA application, or MXLDA3KP7.0CA equivalent, this page delivers verified electrical parameters, IEC61000-4-5 secondary lightning compliance (Class 1–4 with 2–42 Ω source impedance), RoHS-compliant packaging, and real-world design context for ESD/EFT/inductive switching protection.
Technical Context
The MXLDA3KP7.0CA is a surface-mount, bidirectional TVS diode array optimized for fast transient suppression in DC power lines and signal interfaces. Its sub-5 ns response time enables protection against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5) with defined class ratings per source impedance.
It uses a void-free thermosetting epoxy package rated UL94V-0, with tin-lead or matte-tin terminations solderable per MIL-STD-750 Method 2026. Polarity is defined by dot marking; odd-numbered pins are cathodes, confirming dual-channel symmetrical configuration for balanced line protection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0CA | 600 W PPP rating, SMA package, 12.5 V VC @ 38.9 A IPP | Lower energy handling; suitable only for low-energy ESD/EFT, not secondary lightning | Select when board space is constrained and surge threat level is limited to IEC61000-4-2/4-4 only |
| SMCJ7.0CA | 1500 W PPP rating, SMC package, 12.0 V VC @ 125 A IPP | Half the peak power; insufficient for Class 4 IEC61000-4-5 with 2 Ω source | Choose where cost is prioritized over full 3000 W capability and MIL-PRF-19500 screening is unnecessary |
Compared with SMAJ7.0CA and SMCJ7.0CA, the MXLDA3KP7.0CA delivers double the pulse power of SMCJ7.0CA and five times that of SMAJ7.0CA-enabling single-device compliance with demanding IEC61000-4-5 Class 4 and MIL-STD-1275E load dump requirements without parallel staging.

FAQ
What is the clamping voltage of MXLDA3KP7.0CA at its rated peak pulse current?
The MXLDA3KP7.0CA has a maximum clamping voltage (VC) of 12.0 V at 250 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value is measured per standard test methods and guarantees consistent overvoltage limiting across production lots, directly protecting downstream ICs such as microcontrollers and communication transceivers from destructive voltage excursions.
Is MXLDA3KP7.0CA RoHS compliant and what does the 'e3' marking indicate?
Yes, MXLDA3KP7.0CA is RoHS compliant, as confirmed by the 'e3' suffix in its marking per Microsemi's nomenclature guide. The 'e3' designation specifies annealed matte-tin plating meeting JEDEC J-STD-020B Level 1 moisture sensitivity-eliminating dry-pack requirements and enabling standard reflow profiles without pre-bake.
How does MXLDA3KP7.0CA differ from unidirectional variants like MDA3KP7.0A?
MXLDA3KP7.0CA is bidirectional, supporting symmetrical clamping on AC or differential lines, whereas MDA3KP7.0A is unidirectional and intended for DC rail protection with polarity-sensitive placement. The 'C' suffix explicitly denotes bidirectional construction, and MXLDA3KP7.0CA's pinout (Pin 1 and Pin 3 as cathodes, Pin 2 common) enables balanced transient suppression absent in the unidirectional variant.
Can MXLDA3KP7.0CA be used for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MXLDA3KP7.0CA is qualified for IEC61000-4-5 Class 4 secondary lightning protection with 2 Ω source impedance, as documented in the Applications/Benefits section of RF01243 Rev B. Its 3000 W peak pulse power and 12.0 V clamping voltage ensure compliance without derating, unlike lower-rated TVS devices which require parallel staging or fail Class 4 validation.
What is the junction temperature range and why does it matter for MXLDA3KP7.0CA?
MXLDA3KP7.0CA operates across a junction temperature range of –55 °C to +150 °C. This wide range supports deployment in under-hood automotive ECUs, outdoor telecom cabinets, and industrial inverters where ambient temperatures exceed 85 °C-ensuring reliable clamping performance without thermal runaway or parameter drift during sustained surge duty cycles.
