Product details
Overview
DFLS230-7 from Diodes Incorporated is a 30 V, 2.0 A surface-mount Schottky barrier rectifier in PowerDI123 package, featuring 0.49 V max forward voltage at 2.0 A, 1.0 mA max reverse leakage at 30 V, and 40 A non-repetitive surge current capability. It serves as a low-loss polarity protection or recirculating diode in DC power rails of industrial controllers and USB-powered peripherals.
For engineers reviewing the DFLS230-7 datasheet, DFLS230-7 pinout, DFLS230-7 application, or DFLS230-7 equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance under PCB layout constraints, surge current rating for inductive load switching, and RoHS/Green compliance status for end-product certification.
Technical Context
This Schottky rectifier uses guard ring die construction to suppress transient-induced avalanche failure and patented interlocking clip design to sustain 40 A single-half-sine surge without bond wire lift-off. Its low 0.49 V VF at 2.0 A directly reduces conduction loss in 5 V and 3.3 V supply paths.
Thermal performance is defined by two RθJA values: 60 °C/W on a 50.8 mm × 50.8 mm GETEK board (25% anode/75% cathode copper), and 180 °C/W on standard FR-4 with minimal pads - confirming layout-dependent thermal management necessity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - blocks up to 30 V reverse bias without breakdown, suitable for 24 V nominal systems with margin. |
| IF(AV) | 2.0 A @ TJ = +120°C - continuous DC current handling with derating above ambient. |
| VF Max | 0.49 V @ IF = 2.0 A - limits conduction loss to ≤0.98 W per device at full load. |
| IR Max | 1.0 mA @ VR = 30 V - ensures minimal standby leakage in battery-backed circuits. |
| IFSM | 40 A @ 8.3 ms - withstands relay coil or motor winding energy discharge without failure. |
| RθJA | 60 °C/W (GETEK) / 180 °C/W (FR-4) - dictates required copper area for thermal compliance. |
| CT | 75 pF @ VR = 10 V, f = 1 MHz - contributes <0.1 Ω impedance at 100 MHz, relevant for EMI filtering. |
Pinout & Package
Package: PowerDI123 - surface-mount, single-row, 2-terminal plastic package with exposed cathode tab for thermal conduction. Cathode identified by molded band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/power source side; requires minimum 1.8 mm × 1.2 mm copper pad per datasheet. |
| Cathode | Forward current exit / heat sink interface | Exposed metal tab; must be soldered to ≥2.5 mm × 1.8 mm copper pour for thermal relief. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Prevents edge avalanche during voltage transients, enabling reliable operation in noisy industrial environments. |
| Interlocking clip design | Enables 40 A surge current handling without internal wire bond failure, critical for solenoid/motor drive recirculation. |
| Low VF at high current | 0.42 V typ. @ 2.0 A reduces power loss by >30% vs. standard silicon rectifiers in same footprint. |
| Halogen & antimony free | Meets <900 ppm Br/Cl and <1000 ppm Sb thresholds, satisfying IPC-1752A "Green" material reporting requirements. |
Applications
| USB Power Delivery Protection | Industrial PLC I/O Module |
|---|---|
Use Scenario: Prevents reverse-current damage when multiple USB-C ports share common VBUS routing. IC Role / Device Role / Timing Role: Polarity protection diode placed between upstream power source and downstream port controller. Use Value: 0.49 V VF minimizes voltage drop across protection path, preserving PD negotiation headroom. | Use Scenario: Recirculates inductive kickback from 24 V solenoid outputs during turn-off. IC Role / Device Role / Timing Role: Freewheeling diode clamping inductive energy into local rail. Use Value: 40 A IFSM rating safely absorbs 20–30 ms transients typical of 24 V/500 mA solenoids. |
| DC-DC Converter Output Rectification | Automotive Body Control Module |
Use Scenario: Secondary-side rectification in 5 V/2 A buck converter for embedded microcontroller supply. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in cost-sensitive non-isolated converters. Use Value: Low RDS(on)-equivalent conduction loss improves efficiency by ~2.5% over 1N5822 at 1.5 A load. | Use Scenario: Reverse-polarity protection on 12 V accessory power input in BCM subassembly. IC Role / Device Role / Timing Role: Input protection diode blocking battery misconnection events. Use Value: -55°C to +125°C operating range ensures function during cold-cranking and under-hood thermal stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS23-E3/5AT (Vishay) | Same 30 V VRRM, 2 A IF(AV), but VF = 0.5 V max @ 2 A; RθJA = 100 °C/W on FR-4. | Larger thermal footprint required; no interlocking clip design for surge robustness. | Preferred where lower-cost sourcing is prioritized over surge margin. |
| MBR230LSFT1G (ON Semi) | Identical 30 V/2 A rating, VF = 0.45 V max @ 2 A, but IR = 2.0 mA max - double leakage at 30 V. | Higher leakage may impact battery drain in always-on modules. | Selected when tighter VF spec is critical and leakage is managed via system-level sleep control. |
Compared with SS23-E3/5AT and MBR230LSFT1G, DFLS230-7 delivers superior surge immunity (40 A vs. 30 A) and lower leakage (1.0 mA vs. 2.0 mA), making it optimal for inductive load switching and long-battery-life designs where thermal layout is controlled.

FAQ
What is the maximum junction temperature for continuous operation?
The DFLS230-7 supports continuous operation up to +125°C junction temperature, with average forward current derated linearly from 2.0 A at +120°C to zero at +175°C. Thermal design must ensure RθJA and ambient conditions keep TJ within this limit under worst-case load and airflow.
Is the PowerDI123 package lead-free and RoHS compliant?
Yes - DFLS230-7 is fully lead-free and complies with EU RoHS 2011/65/EU and RoHS 3 2015/863/EU directives. Terminal finish is matte tin annealed over copper leadframe, and the molding compound contains no halogens or antimony above regulated thresholds.
Can DFLS230-7 replace a standard PN junction rectifier like 1N4007?
No - DFLS230-7 is a Schottky device with 30 V VRRM, while 1N4007 has 1000 V rating. It replaces low-voltage Schottkys such as SB230 or SS23, not general-purpose silicon rectifiers. Substitution requires matching VRRM, IF(AV), and thermal profile.
What is the significance of the "YM" date code marking?
"YM" is the date code per Diodes' marking standard: "Y" = year (e.g., J = 2022), "M" = month (e.g., 9 = September). The full top-marking "F01A YM" identifies the product type and manufacturing date, enabling traceability and lot-specific reliability data retrieval.
