Product details
Overview
DFLS230L-7 from Diodes Incorporated is a 2.0A surface-mount Schottky barrier rectifier in PowerDI123 package, featuring 30V peak repetitive reverse voltage, 0.375V max forward voltage at 2.0A, and 33A non-repetitive surge current capability. It delivers low power loss and high efficiency for DC-DC output rectification in automotive and industrial power supplies.
For engineers reviewing the DFLS230L-7 datasheet, DFLS230L-7 pinout, DFLS230L-7 application, or DFLS230L-7 equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance junction-to-soldering (10°C/W), surge current rating, RoHS/Green compliance, and AEC-Q–qualified reliability for harsh-environment deployment.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient protection and patented interlocking clip design to sustain 33A single-half-sine surge current. Its low VF (≤0.420V @ 2.0A) and low RθJS (10°C/W) enable efficient operation in space-constrained, thermally demanding layouts.
The device operates across –40°C to +125°C, qualified to JEDEC standards referenced in AEC-Q for high-reliability applications. Total capacitance is 76pF at 10V/1MHz, supporting fast switching with minimal capacitive loading in buck converter outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 24V automotive systems. |
| IF(AV) | 2.0 A - Average forward current at TJ = +121°C; supports continuous output rectification in compact DC-DC converters. |
| VF @ 2.0A | 0.375 V max - Low conduction loss reduces heat generation and improves system efficiency above 85%. |
| IFSM | 33 A - Non-repetitive surge rating enables robustness against load dump or cold-crank transients. |
| RθJS | 10 °C/W - Thermal resistance from junction to solder point; enables direct thermal path to PCB copper for passive cooling. |
| CT @ 10V | 76 pF - Junction capacitance limits switching noise and EMI in high-frequency (>500kHz) synchronous rectifier designs. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB230-E3/52 | Higher VF (0.52V @ 2A), TO-220AC package, no AEC-Q reference | Requires heatsink; unsuitable for space-constrained automotive PCBs | Prefer when higher surge tolerance (50A) outweighs thermal and size constraints |
| SS23H | Same PowerDI123 package, but VF = 0.45V @ 2A and VRRM = 30V; no guard ring or AEC-Q mention | Lacks transient-hardened die; lower reliability in cyclic thermal stress environments | Acceptable for cost-sensitive industrial use where automotive qualification is not required |
Compared with SB230-E3/52 and SS23H, DFLS230L-7 uniquely combines AEC-Q–referenced reliability, 0.375V VF at 2A, and 33A surge in PowerDI123-making it optimal for thermally dense, mission-critical automotive and industrial rectification where size, efficiency, and ruggedness are jointly constrained.

FAQ
What is the maximum junction temperature for continuous operation?
The DFLS230L-7 supports continuous operation up to +125°C junction temperature, validated under IF(AV) = 2.0A with TT = +121°C case temperature per datasheet test condition. Derating is required above this point; thermal design must maintain TJ ≤ 125°C using RθJS = 10°C/W and appropriate PCB copper area.
Is DFLS230L-7 suitable for reverse polarity protection?
Yes-its 30V VRRM and low leakage (<0.26mA @ VR = 5V) make it effective for reverse-voltage blocking in battery-powered systems. When placed anode-to-battery, it blocks reverse current while adding only 0.375V drop at full load, preserving runtime and minimizing heat in portable medical devices.
How does the PowerDI123 package improve thermal performance vs. SOD-123?
PowerDI123 provides 3× lower RθJS (10°C/W vs. ~30°C/W for SOD-123) due to its exposed cathode tab directly soldered to PCB copper. This enables 2.0A operation without heatsink in 121°C ambient, whereas SOD-123 would require forced air or derating below 1.2A.
Does DFLS230L-7 have automotive qualification documentation?
DFLS230L-7 is qualified to JEDEC standards referenced in AEC-Q for high reliability, though full AEC-Q200 testing applies to the automotive-compliant variant DFLS230LQ. The -7 version shares identical die, package, and process-making it widely accepted in non-safety-critical automotive subsystems with documented qualification evidence available upon request.
