Product details
Overview
DFLS260Q from Diodes Incorporated is a 2.0A, 60V surface-mount Schottky barrier rectifier in PowerDI123 package, featuring 0.62V max forward voltage at 2.0A and 0.1mA max reverse leakage at 60V. It delivers low power loss for high-efficiency DC/DC conversion and is AEC-Q101 qualified for automotive polarity protection and recirculating diode applications.
For engineers reviewing the DFLS260Q datasheet, DFLS260Q pinout, DFLS260Q application, or DFLS260Q equivalent, key selection criteria include its 50A non-repetitive surge rating, 67pF junction capacitance at 10V, 12ns reverse recovery time, thermal resistance of 6°C/W (junction-to-solder point), and IATF 16949-certified manufacturing for mission-critical automotive systems.
Technical Context
This Schottky rectifier uses guard ring die construction to suppress transient-induced failure and patented interlocking clip design to sustain 50A single-half-sine surge current. Its low VF (0.56V typ at 2.0A/125°C) enables reduced conduction loss in high-frequency switching topologies.
Rated for -55°C to +150°C operation with 125°C/W junction-to-ambient thermal resistance on FR-4 board, it supports compact automotive PCB layouts while maintaining stable leakage (<0.1mA at 60V/25°C) and fast switching (tRR = 12ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Max) | 60 V - Maximum blocking voltage before breakdown; defines safe operating range in 48V automotive systems. |
| IF(AV) | 2.0 A - Continuous average forward current capability; supports sustained load handling in power rails. |
| VF (Max) | 0.62 V @ 2.0A/25°C - Low conduction loss enabling >92% efficiency in 12V–48V buck converters. |
| IR (Max) | 0.1 mA @ 60V/25°C - Minimal leakage ensures stable voltage hold-off during system standby modes. |
| tRR | 12 ns - Fast reverse recovery minimizes switching loss and EMI in >100kHz SMPS designs. |
| RθJS | 6 °C/W - Low junction-to-solder-point thermal resistance enables direct thermal coupling to copper pour for thermal management. |
| ESD HBM | 4000 V - Robust electrostatic discharge immunity suitable for automated assembly and field-replaceable modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB260-E3/54 (Vishay) | Same 60V/2A rating but TO-277 package; VF = 0.72V max; RθJA = 150°C/W; no AEC-Q101 certification. | Limited to industrial/commercial use; unsuitable for PPAP-controlled automotive production. | Select only if cost-driven and automotive qualification is not required. |
| SS26HE3_A/H (Vishay) | PowerDI123 package, AEC-Q101 qualified, but VF = 0.75V max and IR = 0.5mA max at 60V - higher loss and leakage. | Acceptable for lower-temp ambient environments but less efficient in high-power density modules. | Prefer when legacy footprint compatibility is mandatory and 0.13V higher VF is tolerable. |
Compared with SB260-E3/54 and SS26HE3_A/H, DFLS260Q provides the lowest VF (0.62V), tightest IR (0.1mA), and full automotive compliance stack - making it optimal for space-constrained, thermally demanding, and safety-critical vehicle subsystems.

FAQ
What is the maximum junction temperature for continuous operation?
The DFLS260Q has an operating junction temperature range of -55°C to +150°C. For continuous operation at full 2.0A average current, thermal design must ensure TJ does not exceed 150°C - typically requiring ≥250mm² of 2oz copper on the cathode pad per the recommended layout in DS37113.
Is the PowerDI123 package lead-free and RoHS compliant?
Yes. The DFLS260Q features matte tin annealed over copper leadframe, fully compliant with EU RoHS Directive 2015/863/EU (RoHS 3), and classified as "Green" with <900ppm bromine, <900ppm chlorine, and <1000ppm antimony.
Can DFLS260Q replace standard PN junction rectifiers in existing designs?
Yes - with design validation. Its lower VF reduces conduction loss, but its higher IR at elevated temperatures requires checking reverse-bias stability in high-ambient applications. Also verify layout compatibility: PowerDI123 footprint differs from SMA/SMB packages.
Does DFLS260Q require derating for capacitive loads?
Yes. Per datasheet guidance, average forward current must be derated by 20% when used with capacitive loads to prevent excessive peak current stress during charging transients - e.g., limit IF(AV) to 1.6A in bulk-capacitor input stages.
