Product details
Overview
DFLS260-7 from Diodes Incorporated is a 2.0A surface-mount Schottky barrier rectifier in PowerDI®123 package, rated for 60V peak repetitive reverse voltage and 50A non-repetitive surge current. It delivers low forward voltage (0.56V at 2.0A/125°C), high efficiency, and transient protection via guard ring die construction. Used in DC-DC converter outputs, USB power delivery, and automotive auxiliary power rails.
For engineers reviewing the DFLS260-7 datasheet, DFLS260-7 pinout, DFLS260-7 application, or DFLS260-7 equivalent, key selection criteria include VF vs. temperature stability, RθJS of 6°C/W for thermal design, 67pF junction capacitance at 10V, and compliance with automotive-grade variants (DFLS260Q) for harsh-environment deployment.
Technical Context
This Schottky rectifier employs a guard ring die structure to suppress avalanche-induced failure during voltage transients and features a patented interlocking clip design that enhances mechanical robustness and surge current handling. Its low VF minimizes conduction loss in high-frequency switching topologies.
The device operates across –65°C to +150°C, with thermal resistance junction-to-soldering point (RθJS) of 6°C/W enabling direct PCB copper pad thermal coupling. Junction-to-ambient (RθJA) is 125°C/W on standard FR-4 with minimum recommended 2oz copper layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS26-E3/57T (Vishay) | Same 2A/60V rating but higher VF (0.75V @ 2A/25°C); RθJA 150°C/W | Lacks guard ring and interlocking clip; lower surge robustness (30A IFSM) | Acceptable for cost-sensitive consumer adapters where thermal headroom exists |
| SB260-E3/57T (Vishay) | Identical VF spec (0.56V @ 2A/125°C) but no RoHS 3 or "Green" certification | Not qualified for automotive or medical use due to halogen content | Only suitable for legacy industrial designs with relaxed environmental compliance |
Compared with SS26-E3/57T and SB260-E3/57T, DFLS260-7 provides superior thermal performance (RθJS = 6°C/W), guaranteed surge resilience (50A), and full regulatory alignment-making it the preferred choice for space-constrained, high-reliability power conversion.

FAQ
What is the maximum junction temperature for continuous operation?
The DFLS260-7 supports continuous operation up to +150°C junction temperature, verified per JEDEC JESD22-A108. Derating begins above +125°C ambient, with IF(AV) reduced linearly to zero at +150°C using the curve in Figure 5 of DS31476 Rev. 4-2.
Is the PowerDI123 package compatible with standard SMT reflow profiles?
Yes-the PowerDI123 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260°C, 60-second duration). Matte tin annealed terminals ensure reliable wetting without voiding.
Does DFLS260-7 meet automotive qualification requirements?
No-DFLS260-7 is not AEC-Q101 qualified. The automotive-compliant variant is DFLS260Q, documented separately under DS31476Q, which includes additional stress testing and PPAP documentation for vehicle subsystems.
How does the guard ring die construction improve reliability?
The guard ring structure surrounds the active junction to distribute electric field gradients during overvoltage transients, preventing localized avalanche and premature breakdown. This extends operational lifetime in applications exposed to load dump or ESD events per ISO 16750-2.
