Product details
Overview
DFLS130L-7 from Diodes Incorporated is a 1.0A surface-mount Schottky barrier rectifier in PowerDI123 package, rated for 30V peak repetitive reverse voltage, 50A non-repetitive surge current, and 0.328V forward voltage at 1.0A. It delivers low power loss and high efficiency in DC/DC converter output rectification and USB power path protection.
For engineers reviewing the DFLS130L-7 datasheet, DFLS130L-7 pinout, DFLS130L-7 application, or DFLS130L-7 equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance junction-to-soldering (10°C/W), surge current capability (50A), RoHS/Green compliance, and cathode-band polarity marking for PCB layout verification.
Technical Context
This Schottky diode uses guard ring die construction to enhance transient voltage immunity and patented interlocking clip design to sustain high surge currents without bond-wire failure. Its low VF (0.328V @ 1.0A) and low CT (76pF @ 10V) support high-frequency switching in compact power supplies.
Thermal performance is optimized via direct die-to-cathode tab conduction (RθJS = 10°C/W), enabling reliable operation up to +125°C junction temperature. The PowerDI123 package provides 1.67W power dissipation on a 2"×2" GETEK board with defined copper pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum reverse blocking voltage before breakdown; defines safe operating range in 24V rail clamping and 5V/3.3V buck converter outputs. |
| IF(AV) | 1.0 A - Average forward current rating at TJ = +121°C; supports continuous load in portable charger and PoE-powered device front-end rectification. |
| VF @ 1.0A | 0.328 V - Measured forward voltage drop; reduces conduction loss by ~35% vs. standard silicon diodes, improving efficiency in low-voltage, high-current paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB130-E3/54 (Vishay) | Same 30V/1A rating but TO-277 package; higher RθJA (120°C/W), no interlocking clip design. | Larger footprint; less suitable for ultra-thin designs; lower surge margin (30A IFSM). | Prefer when legacy TO-277 layout exists and thermal budget allows higher ambient rise. |
| SS13 (ON Semiconductor) | 30V/1A Schottky in SMA package; VF = 0.45V @ 1.0A; RθJA = 130°C/W; no guard ring. | Higher conduction loss (+37% vs. DFLS130L-7); limited surge robustness; not automotive-compliant. | Select only for cost-sensitive, non-automotive, low-frequency (<500kHz) applications where efficiency is secondary. |
Compared with SB130-E3/54 and SS13, DFLS130L-7 offers superior thermal performance (RθJS = 10°C/W), higher surge tolerance (50A), and integrated transient hardening-making it optimal for space-constrained, high-reliability DC/DC and automotive power interfaces.

FAQ
What is the maximum junction temperature and how is it validated?
The DFLS130L-7 has an operating junction temperature range of –40°C to +125°C, verified per JEDEC JESD22-A104 thermal cycling and JESD22-A108 high-temperature operating life testing. Thermal derating begins above +121°C average forward current limit, with RθJS = 10°C/W measured from die center to cathode tab solder joint.
Is the PowerDI123 package compatible with standard reflow profiles?
Yes-the PowerDI123 package is qualified for IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard lead-free reflow profiles (peak 260°C, 30 seconds max). Its matte tin annealed copper leadframe ensures reliable wetting and void-free solder joints on FR-4 and GETEK substrates.
How does the guard ring construction improve reliability?
The guard ring die structure extends the depletion region beyond the active junction, suppressing edge breakdown during voltage transients. This increases ESD robustness (HBM > 8kV) and prevents premature avalanche failure under repetitive 30V reverse bias, especially in unregulated input stages like USB-C receptacles.
Can DFLS130L-7 replace standard PN-junction diodes in existing designs?
Yes-its 30V VRRM and 1.0A IF(AV) match common 1N5819 equivalents, but with significantly lower VF (0.328V vs. 0.475V) and faster recovery. Layout changes may be needed due to PowerDI123's exposed cathode tab; thermal pad area must follow Diodes' recommended 2.40mm × 1.50mm footprint for optimal RθJS performance.
