Product details
Overview
DFLS130-7 from Diodes Incorporated is a 1.0A surface-mount Schottky barrier rectifier in PowerDI123 package, rated for 30V peak repetitive reverse voltage, 0.36V typical forward voltage at 1.0A, and 35A non-repetitive surge current. It delivers low power loss and high efficiency in DC/DC converter output rectification and USB power delivery circuits.
For engineers reviewing the DFLS130-7 datasheet, DFLS130-7 pinout, DFLS130-7 application, or DFLS130-7 equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance junction-to-soldering (10°C/W), surge capability (35A @ 8.3ms), and RoHS-compliant matte tin annealed terminals on copper leadframe.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient protection and withstand repetitive voltage spikes without degradation. Its low VF (0.36V max at IF = 1.0A) and low RθJS (10°C/W) enable high-efficiency operation in space-constrained, thermally demanding applications such as portable chargers and automotive body electronics.
Rated for -55°C to +125°C operating temperature and qualified to JEDEC reliability standards, it supports stable performance under thermal cycling and high-humidity conditions. The PowerDI123 package provides optimized thermal path via cathode tab soldering and meets UL 94V-0 flammability rating.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS13-E3/5AT (Vishay) | Same 30V VRRM, 1A IF(AV), but VF = 0.45V @ 1A (higher conduction loss); RθJA = 120°C/W on FR-4 | Limited to lower-power, less thermally constrained designs due to higher thermal resistance and VF | Select when legacy footprint compatibility with SMB package is required; not drop-in for PowerDI123 layout |
| SB130-TB (ON Semiconductor) | Identical PowerDI123 package, 30V/1A rating, VF = 0.37V @ 1A; slightly higher IR (2.0 mA @ 30V) | Acceptable in most DFLS130-7 applications but requires verification of leakage sensitivity in battery-holdup circuits | Preferred for second-source assurance where identical mechanical fit and near-identical electrical behavior are needed |
Compared with SS13-E3/5AT and SB130-TB, DFLS130-7 offers the lowest VF (0.36V) and best thermal resistance (RθJS = 10°C/W), making it optimal for thermally dense, high-efficiency 1A rectification where board area and thermal budget are tightly constrained.

FAQ
What is the maximum junction temperature for continuous operation of DFLS130-7?
The DFLS130-7 has an operating junction temperature range of -55°C to +125°C. Continuous operation at TJ = +125°C is permitted when thermal design ensures actual junction temperature remains within this limit, verified using RθJS = 10°C/W and measured solder-point temperature.
Is DFLS130-7 suitable for automotive applications?
DFLS130-7 itself is not AEC-Q200 qualified; however, Diodes offers automotive-grade equivalents (e.g., DFLS130Q-7) with AEC-Q200 qualification, PPAP capability, and IATF 16949 manufacturing. Standard DFLS130-7 may be used in non-safety-critical automotive subsystems pending internal qualification.
How does the guard ring die construction improve reliability?
The guard ring structure surrounds the active junction to suppress edge breakdown and mitigate avalanche-induced damage during transient voltage events. This design enhances ruggedness against repetitive line transients and ESD pulses without degrading forward characteristics over lifetime.
What is the recommended PCB pad layout for optimal thermal performance?
For best thermal conduction, use the recommended cathode pad: 25.4 mm × 25.4 mm on GETEK board (RθJA = 60°C/W) or ≥20 mm² copper area with multiple thermal vias to inner ground planes. Anode pad should be 1.8 mm × 1.2 mm; avoid excessive solder mask coverage over cathode tab.
