Product details
Overview
DFLS230LH-7 from Diodes Incorporated is a 2.0A, 30V high-efficiency Schottky barrier rectifier in PowerDI®123 package, featuring low forward voltage (0.375V at 2A/125°C), low leakage current (0.2mA at 30V/100°C), and 75A non-repetitive surge capability. It serves as a primary output rectifier in compact DC-DC converters for automotive infotainment power supplies.
For engineers reviewing the DFLS230LH-7 datasheet, DFLS230LH-7 pinout, DFLS230LH-7 application, or DFLS230LH-7 equivalent, key selection criteria include VF vs. temperature performance, RθJS of 6°C/W, JEDEC-qualified reliability, and PowerDI123 thermal pad layout compatibility with FR-4 PCBs.
Technical Context
This Schottky rectifier uses guard ring die construction to suppress transient-induced avalanche failure and patented interlocking clip design to sustain 75A single-half-sine surge without bond wire lift-off. Its low 85pF capacitance at 10V enables stable operation in high-frequency switching topologies up to 1MHz.
The device operates across -65°C to +150°C junction temperature range and meets JEDEC high-reliability standards. Its matte tin-annealed copper leadframe ensures MIL-STD-202-compliant solderability and supports automated reflow assembly on standard SMT lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for input/output rail separation in buck-derived topologies. |
| IF(AV) | 2.0 A - Average forward current rating at TA=25°C; defines continuous conduction mode capability in 500kHz–1MHz DC-DC outputs. |
| VF @ 2A/125°C | 0.375 V - Confirmed forward drop under worst-case thermal condition; directly determines conduction loss in thermally constrained layouts. |
| IR @ 30V/100°C | 0.200 mA - Reverse leakage at elevated temperature; critical for standby power budgeting in always-on automotive modules. |
| RθJS | 6 °C/W - Junction-to-solder-point thermal resistance; enables accurate thermal modeling when mounted on 2oz copper pads per Diodes' recommended layout. |
| CT @ 10V/1MHz | 85 pF - Total junction capacitance; limits high-frequency ringing and EMI generation in fast-switching synchronous rectifier circuits. |
Pinout & Package
Package: PowerDI®123 - surface-mount, single-diode configuration with exposed cathode tab for thermal dissipation. Molded green compound (UL 94V-0), 0.01g mass, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current entry point | Connected to switch node or transformer secondary; requires low-inductance trace routing to minimize voltage overshoot. |
| Cathode | Output current exit point | Exposed metal tab soldered to PCB copper pour; primary thermal path to board; must match Diodes' recommended 2.4mm × 4.1mm pad layout. |
| Cathode Band | Polarity indicator | Visible marking on top surface; identifies cathode terminal for automated optical inspection and manual verification during rework. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Prevents edge avalanche during load dump transients (ISO 7637-2 Pulse 5a), extending lifetime in automotive 12V systems. |
| Patented interlocking clip | Enables 75A IFSM without internal mechanical failure-critical for surviving cold-crank events in engine control units. |
| Low VF at high temperature | 0.375V at 2A/125°C reduces conduction loss by >25% versus standard Schottkys, improving efficiency in sealed enclosures. |
| Green molding compound | Halogen- and antimony-free (<900ppm Br+Cl, <1000ppm Sb); satisfies automotive OEM environmental compliance requirements (e.g., GMW3172). |
Applications
| Automotive Infotainment Power Supply | USB-C PD Adapter Secondary Rectification |
|---|---|
Use Scenario: 12V-to-5V/3.3V buck converter supplying head unit MCU, display driver, and audio codec. IC Role / Device Role / Timing Role: Output rectifier replacing conventional PN diode to reduce conduction loss and improve light-load efficiency.

Use Scenario: 24V-to-3.3V isolated DC-DC converter powering LoRaWAN sensor node with 10-year battery life target. IC Role / Device Role / Timing Role: Output rectifier in miniature flyback transformer secondary winding. Use Value: 0.2mA IR at 100°C ensures standby current remains below 1µA system threshold, preserving battery longevity. | Use Scenario: High-side rectifier in constant-current LED driver for automotive interior lighting. IC Role / Device Role / Timing Role: Reverse-polarity protection and freewheeling path during PWM dimming transitions. Use Value: Guard ring structure withstands 100V transients from inductive kickback, eliminating need for external TVS diode. |
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 | Higher VF (0.5V @ 2A/25°C), no guard ring, RθJS = 10°C/W | Limited to commercial-grade, non-automotive applications due to lower surge and thermal performance | Select only if cost sensitivity outweighs thermal margin and transient robustness requirements. |
| SB230-E3/57T | Same 30V/2A rating but TO-277 package; VF = 0.45V @ 2A/25°C; no JEDEC qualification | Requires larger PCB footprint and lacks automotive change control documentation | Choose only when legacy TO-277 footprint compatibility is mandatory and AEC-Q support is not required. |
Compared with SS23-E3/5AT and SB230-E3/57T, DFLS230LH-7 delivers superior thermal resistance (6°C/W), guaranteed transient immunity via guard ring, and documented JEDEC reliability-making it the only option qualified for production automotive power rails requiring PPAP and IATF 16949 traceability.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The DFLS230LH-7 has an operating junction temperature range of -65°C to +150°C. Continuous operation at +150°C is permitted only when thermal design ensures actual TJ does not exceed this limit-verified using RθJS = 6°C/W and measured ambient temperature plus power dissipation.
Does this part meet AEC-Q200 stress testing requirements?
No-DFLS230LH-7 is qualified to JEDEC high-reliability standards but is not AEC-Q200 certified. For automotive applications requiring AEC-Q200, Diodes offers the Q-suffix variant DFLS230LHQ-7, which undergoes full stress testing and PPAP documentation.
Can the PowerDI123 package be hand-soldered reliably?
Yes-the PowerDI123 package supports hand-soldering using a fine-tip iron (≤0.5mm) and controlled heat profile. The exposed cathode tab requires ≥3 seconds dwell at 350°C with flux-core solder; avoid excessive pressure to prevent die cracking per Diodes' mounting guidelines.
How does the interlocking clip design improve surge performance?
The interlocking clip mechanically anchors the die to the leadframe, preventing bond wire detachment and die lift-off during 75A IFSM events. This eliminates the common failure mode seen in standard clip-bonded Schottkys under ISO 7637-2 load dump conditions.
