Product details
Overview
MXDA3KP6.5AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 6.5 V standoff voltage (VWM), 7.22–7.98 V breakdown voltage (V(BR)), and 11.2 V clamping voltage (VC) at 267.9 A peak pulse current, designed for secondary lightning protection per IEC61000-4-5 in telecom power interfaces.
For engineers reviewing the MXDA3KP6.5AE3 datasheet, MXDA3KP6.5AE3 pinout, MXDA3KP6.5AE3 application, or MXDA3KP6.5AE3 equivalent, key selection criteria include its 6.5 V working voltage, 1000 µA standby current at VWM, RoHS-compliant e3 termination, and MIL-PRF-19500 upscreening capability for high-reliability aerospace and industrial systems.
Technical Context
The MXDA3KP6.5AE3 operates as a unidirectional avalanche diode-based TVS, delivering sub-100 ps response time to clamp transients induced by ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5). Its 3000 W peak pulse power rating is specified at 10/1000 µs waveform with ≤0.05% duty factor.
It features a void-free UL94V-0 thermosetting epoxy package with tin-lead or matte-tin plating, polarity defined by dot-marked Pin 1 (cathode), and moisture sensitivity level 1-no dry pack required per IPC/JEDEC J-STD-020B. Standby current ID is 500 µA max at 6.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse operating voltage before clamping begins |
| V(BR) min–max | 7.22–7.98 V @ 10 mA - ensures reliable avalanche conduction onset across temperature and lot variation |
| VC @ IPP | 11.2 V @ 267.9 A - clamping voltage during 10/1000 µs surge, limiting downstream IC stress |
| ID @ VWM | 500 µA - low leakage preserves system efficiency in always-on power rails |
| PPP | 3000 W @ 10/1000 µs - handles high-energy transients without thermal runaway |
| TJ range | −55 °C to +150 °C - supports operation in extended industrial and automotive under-hood environments |
| RoHS | e3 - lead-free matte-tin termination compliant with EU Directive 2011/65/EU |
Pinout & Package
MXDA3KP6.5AE3 uses a 2-pin SMD package (case outline per RF01243, Page 6) with cathode marked by dot on top; Pin 1 = cathode, Pin 2 = anode. Body dimensions: 21.03–22.05 mm × 6.86–7.87 mm × 8.64–9.65 mm (L×W×H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; clamps when voltage exceeds V(BR) relative to Pin 2 |
| Pin 2 | Anode | Typically tied to ground or lower-potential rail; completes conduction path during surge |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional construction | Enables DC-biased line protection (e.g., +12 V supply) without reverse conduction path |
| 3000 W peak pulse power | Sustains high-energy surges from inductive switching or lightning coupling without degradation |
| MIL-PRF-19500 screening option | Supports high-reliability qualification for defense/aerospace programs requiring lot traceability and 3σ ID screening |
| Level 1 moisture sensitivity | Eliminates bake-out requirement prior to reflow, reducing assembly cost and PCB warpage risk |
| UL94V-0 epoxy body | Provides flame-retardant mechanical integrity in overvoltage fault conditions |
Applications
| Telecom Power Interface Protection | Industrial PLC I/O Module Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A | 600 W PPP rating, same VWM and VC; smaller SMB package (3.5 × 4.6 mm vs. 21 × 7 mm) | Lower energy handling limits use to sub-100 A surges; unsuitable for IEC61000-4-5 Class 3+ | Select SMBJ6.5A only for space-constrained consumer designs with verified <150 A threat levels. |
| SMCJ6.5A | 1500 W PPP, same VWM/VC; SMC package (7.1 × 6.2 mm), ~40% smaller footprint than MXDA3KP6.5AE3 | Half the surge capacity; requires parallel placement for 3000 W compliance | Choose SMCJ6.5A where board area is critical and surge testing confirms dual-device derating suffices. |
Compared with SMBJ6.5A and SMCJ6.5A, MXDA3KP6.5AE3 delivers double the pulse power of SMCJ6.5A and five times that of SMBJ6.5A in a single device, eliminating layout complexity and thermal coupling concerns in high-reliability 3000 W surge paths.

FAQ
What is the clamping voltage of MXDA3KP6.5AE3 at its rated peak pulse current?
The MXDA3KP6.5AE3 has a maximum clamping voltage (VC) of 11.2 V at its rated peak pulse current (IPP) of 267.9 A under 10/1000 µs waveform conditions. This value is measured per Figure 2 in RF01243 Rev B and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MXDA3KP6.5AE3 maintains this clamping performance across its full operating temperature range.
Is MXDA3KP6.5AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXDA3KP6.5AE3 is RoHS compliant. The 'e3' suffix explicitly denotes matte-tin (Sn) termination per JEDEC J-STD-020, satisfying EU Directive 2011/65/EU and eliminating lead content in the solderable terminals. This marking appears in the part nomenclature diagram on page 2 of RF01243 Rev B and is verified in the Mechanical and Packaging section.
Can MXDA3KP6.5AE3 be used for bidirectional transient protection?
No, MXDA3KP6.5AE3 is unidirectional only. Its part number lacks the 'C' suffix (e.g., MDA3KP6.5CE3) required for bidirectional variants. The polarity is fixed: Pin 1 is cathode, Pin 2 is anode. Using it in reverse-biased AC applications would result in forward conduction and failure. For bidirectional protection, select MDA3KP6.5CE3 instead.
What is the maximum standby current ID for MXDA3KP6.5AE3 at its rated standoff voltage?
The maximum standby current (ID) for MXDA3KP6.5AE3 is 500 µA when biased at its rated reverse standoff voltage (VWM) of 6.5 V and measured at 25 °C. This value is confirmed in the Electrical Characteristics table on page 3 of RF01243 Rev B and reflects low leakage essential for battery-backed or low-power systems.
Does MXDA3KP6.5AE3 meet IEC61000-4-5 Class 4 lightning surge immunity?
MXDA3KP6.5AE3 supports IEC61000-4-5 Class 4 only with 42 Ω source impedance, as stated in the Applications/Benefits section (page 1). It is not rated for Class 4 under 12 Ω or 2 Ω sources-those require lower-voltage variants like MDA3KP6.0CA. Verification must reference Figure 3's derating curve for ambient temperature effects on PPP.
