Product details
Overview
MDA3KP6.5A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability overvoltage protection in power rails and signal lines. It features a 6.5 V reverse standoff voltage (VWM), 7.22–7.98 V breakdown voltage (V(BR)), 11.2 V clamping voltage at 267.9 A peak pulse current, and operates from –55 °C to +150 °C - deployed in industrial motor drives, telecom power supplies, and automotive ECUs.
For engineers reviewing the MDA3KP6.5A datasheet, MDA3KP6.5A pinout, MDA3KP6.5A application, or MDA3KP6.5A equivalent, key selection criteria include its 10.3 µA standby current at VWM, 100 ps response time, IEC 61000-4-2/4-4/4-5 compliance, and MIL-PRF-19500 upscreening capability for aerospace-grade reliability validation.
Technical Context
The MDA3KP6.5A functions as a unidirectional avalanche diode-based TVS, triggered when transient voltage exceeds its 7.22 V minimum breakdown threshold. Its clamping action limits downstream voltage to ≤11.2 V at 267.9 A (10/1000 µs waveform), with <100 ps response time ensuring ESD and fast switching transient suppression.
It is rated for 3000 W peak pulse power under standard 10/1000 µs conditions, derates linearly above 25 °C per Figure 3, and maintains Level 1 moisture sensitivity (IPC/JEDEC J-STD-020B) without dry pack requirement - enabling standard reflow assembly.
Key Specifications

Pinout & Package
MDA3KP6.5A uses a 3-pin SMD package (case outline per Page 6 of RF01243 Rev B): void-free UL94V-0 epoxy body, tin-lead or matte-tin terminations, pin 1 identified by dot marking, odd-numbered pins are cathodes.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A | 600 W rating (vs. 3000 W); 10.3 V VC @ 32.4 A; same VWM and package footprint | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Class 3+ or lightning-level events | Select MDA3KP6.5A where 3000 W surge immunity is required; SMBJ6.5A only for board-level ESD/EFT only |
| SMCJ6.5A | 1500 W rating; 11.2 V VC @ 134 A; identical VWM and unidirectional polarity | Half the peak power handling; insufficient for 42 Ω IEC 61000-4-5 Class 4 testing | MDA3KP6.5A provides double the PPP margin of SMCJ6.5A - critical for mission-critical industrial systems |
Compared with SMBJ6.5A and SMCJ6.5A, the MDA3KP6.5A delivers 5× and 2× higher peak pulse power respectively, enabling compliance with stringent secondary lightning standards while maintaining identical 6.5 V standoff and SMD mounting - making it the sole choice for high-energy transient environments.

FAQ
What is the clamping voltage of MDA3KP6.5A at its rated peak pulse current?
The MDA3KP6.5A 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 standard test methods defined in the datasheet and ensures downstream circuitry remains within safe operating voltage limits during surge events. The MDA3KP6.5A maintains this clamping performance across its full operating temperature range.
Is MDA3KP6.5A RoHS compliant and what does the 'e3' suffix indicate?
Yes, MDA3KP6.5A is RoHS compliant, indicated by the 'e3' marking per the part nomenclature on page 2 of RF01243 Rev B. The 'e3' designation specifies annealed matte-tin plating meeting JEDEC/IPC standards, with lead-free terminations and full compliance to Directive 2011/65/EU. This applies to all units shipped post-compliance transition; the MDA3KP6.5A contains no restricted substances above threshold limits.
Can MDA3KP6.5A be used for bidirectional transient protection?
No, MDA3KP6.5A is unidirectional only. Its part number lacks the 'C' suffix specified for bidirectional variants (e.g., MDA3KP6.5CA). The device conducts only during positive transients relative to its anode (Pin 2), making it unsuitable for AC-coupled or bipolar signal lines. For bidirectional protection, MDA3KP6.5CA must be selected - it shares the same VWM and PPP rating but differs in symmetry and breakdown behavior.
What is the maximum operating temperature for MDA3KP6.5A and how does derating affect its surge rating?
The MDA3KP6.5A supports a junction temperature range of –55 °C to +150 °C. Its 3000 W peak pulse power rating is specified at 25 °C and derates linearly above that point per Figure 3 in RF01243 Rev B - e.g., at +125 °C, the usable PPP drops to approximately 65% of rated value. Designers must apply thermal modeling to ensure sustained surge duty cycles remain within the derated envelope.
Does MDA3KP6.5A require special handling or baking before PCB assembly?
No, MDA3KP6.5A does not require baking or dry pack storage. It is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ≤30 °C/60% RH and processed using standard SnPb or lead-free reflow profiles without preconditioning. The void-free epoxy package and matte-tin terminations ensure compatibility with automated placement and reflow soldering.
