Product details
Overview
MXDA3KP8.0AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 8.0 V standoff voltage (VWM), 8.89–9.83 V breakdown voltage (V(BR)), and 13.6 V clamping voltage (VC) at 220.6 A peak pulse current. It provides secondary lightning protection per IEC61000-4-5 (42 Ω, Class 1–4), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in telecom power interfaces.
For engineers reviewing the MXDA3KP8.0AE3 datasheet, MXDA3KP8.0AE3 pinout, MXDA3KP8.0AE3 application, or MXDA3KP8.0AE3 equivalent, key selection criteria include its 8.0 V VWM rating, 13.6 V VC at 220.6 A IPP, RoHS-compliant e3 termination, -55°C to +150°C operating junction temperature, and unidirectional polarity for DC-biased signal/power line protection.
Technical Context
The MXDA3KP8.0AE3 is a single-channel, unidirectional TVS diode designed for high-energy transient suppression in DC power rails and low-voltage data lines. Its 10/1000 µs waveform-rated 3000 W peak pulse power and sub-100 ps response time enable effective clamping of fast-rising ESD events and slower lightning-induced surges.
It operates with a maximum standby current of 50 µA at 8.0 V VWM and exhibits forward surge capability of 200 A at 8.3 ms half-sine, supporting robust overvoltage resilience without latch-up. Polarity is defined by odd-numbered pins as cathodes, consistent with its dual-pin SMD package layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | 600 W PPP rating, same VWM and VC but lower IPP (69.4 A); DO-214AC (SMA) package | Lower energy handling limits use to lighter-duty I/O or signal-line protection | Select SMAJ8.0A only when surge threat level is ≤IEC61000-4-5 Class 2 (42 Ω) |
| 1.5KE8.0A | 1500 W PPP, axial-leaded DO-201AD package, higher leakage (100 µA), no RoHS e3 marking | Through-hole mounting; unsuitable for high-density SMT layouts or automated assembly | Choose 1.5KE8.0A only for legacy through-hole designs requiring field-replaceable components |
Compared with SMAJ8.0A and 1.5KE8.0A, MXDA3KP8.0AE3 delivers 5× higher peak pulse power than SMAJ8.0A and 2× higher than 1.5KE8.0A, enabling single-device Class 4 lightning protection in compact SMT form factor with guaranteed RoHS compliance and full traceability.

FAQ
What is the clamping voltage of MXDA3KP8.0AE3 at its rated peak pulse current?
The MXDA3KP8.0AE3 has a maximum clamping voltage (VC) of 13.6 V at its rated peak pulse current (IPP) of 220.6 A under 10/1000 µs waveform conditions. This value is measured per standard test methods and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MXDA3KP8.0AE3 maintains this clamping performance across its full operating temperature range of -55°C to +150°C.
Is MXDA3KP8.0AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXDA3KP8.0AE3 is RoHS compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide. The 'e3' designation specifies annealed matte-tin plating meeting JEDEC/IPC standards, with lead content below RoHS thresholds and full compatibility with lead-free reflow processes. This compliance is verified per manufacturer documentation RF01243 Rev B and applies to all units shipped with this suffix.
How does the polarity marking work on MXDA3KP8.0AE3?
MXDA3KP8.0AE3 uses odd-numbered pins as cathodes, with Pin 1 identified by a dot on the top surface of the DO-214AB package. As a unidirectional TVS, it conducts only when the cathode is at higher potential than the anode-i.e., during positive transients on the line connected to Pin 1. This polarity must be observed during PCB layout to ensure correct clamping direction relative to the protected rail and ground reference.
Can MXDA3KP8.0AE3 be used for bidirectional transient protection?
No, MXDA3KP8.0AE3 is strictly unidirectional and cannot provide symmetrical clamping for AC or bipolar signal lines. For bidirectional protection, Microsemi offers the C-suffix variants (e.g., MDA3KP8.0CE3), which feature back-to-back diode construction. Using MXDA3KP8.0AE3 in bidirectional applications risks failure during negative transients, as it lacks reverse conduction capability beyond its specified standoff voltage.
What is the maximum allowable standoff voltage for MXDA3KP8.0AE3 in a 12 V nominal system?
MXDA3KP8.0AE3 has a rated working standoff voltage (VWM) of 8.0 V, meaning it is intended for systems where the maximum continuous operating voltage does not exceed this value. In a 12 V nominal system, it is unsuitable as primary protection unless derated-for example, used downstream of a DC-DC converter outputting ≤8 V. For 12 V rails, higher-VWM variants like MXDA3KP12AE3 (VWM = 12 V) are appropriate to avoid premature conduction.
