Product details
Overview
DFLS2100Q-7 from Diodes Incorporated is a 100 V, 2.0 A high-voltage Schottky barrier rectifier in PowerDI®123 package, featuring 0.86 V max forward voltage at 2.0 A and 1 µA max reverse leakage at 100 V. It serves as a boost diode, reverse polarity protection device, or blocking diode in DC/DC converters and automotive power supplies.
For engineers reviewing the DFLS2100Q-7 datasheet, DFLS2100Q-7 pinout, DFLS2100Q-7 application, or DFLS2100Q-7 equivalent, key selection criteria include its AEC-Q101 qualification, 50 A non-repetitive surge rating, low thermal resistance (7 °C/W junction-to-solder), and high-temperature stability up to +175°C.
Technical Context
This Schottky rectifier uses a planar epitaxial construction with a patented interlocking clip design to achieve high surge current capability and robust thermal performance. Its low VF and reduced high-temperature IR minimize conduction loss and mitigate thermal runaway risk in continuous high-load operation.
Rated for 100 V peak repetitive reverse voltage and 2.0 A average rectified output current, it supports 60 Hz single-phase half-wave rectification with 20% derating for capacitive loads. Switching speed is characterized by 9 ns reverse recovery time under defined test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Withstands up to 100 V reverse bias without breakdown, suitable for 48 V automotive and industrial bus applications. |
| IO | 2.0 A - Sustains continuous average forward current up to 2.0 A on FR-4 PCB with recommended copper pad layout. |
| VF(MAX) | 0.86 V @ 2.0 A - Limits conduction loss to ≤1.72 W at full load, improving system efficiency in compact power stages. |
| IR(MAX) | 1 µA @ 100 V - Ensures minimal leakage-induced power waste and stable blocking behavior at rated voltage and +25°C. |
| IFSM | 50 A - Handles 8.3 ms half-sine surge events common in input stage transients and hot-swap conditions. |
| tRR | 9 ns - Enables high-frequency switching operation with low switching loss in SMPS and synchronous rectifier auxiliary paths. |
Pinout & Package
Package: PowerDI®123 - Surface-mount, single-ended, cathode-band marked plastic package with matte tin annealed terminals; 0.01 g weight; UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit (e.g., switch node in boost topology); requires thermal pad connection for RθJS = 7 °C/W performance. |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; connected to higher-potential rail (e.g., output capacitor positive); serves as primary heat path to PCB via soldered tab. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.86 V max at 2.0 A reduces I²R losses and enables smaller heatsinking in space-constrained 12–48 V systems. |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (6 kV HBM), supporting PPAP-compliant designs. |
| Patented interlocking clip | Enhances mechanical bond strength between die and leadframe, enabling 50 A surge rating without wirebond failure. |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets global environmental compliance mandates. |
Applications
| Automotive DC/DC Converters | Industrial Power Supplies |
|---|---|
Use Scenario: Step-up conversion from 12 V battery to 24 V or 48 V rail in ADAS camera modules and infotainment head units. IC Role / Device Role / Timing Role: Boost diode in synchronous or quasi-resonant flyback topologies, conducting during high-side switch off-time. Use Value: Low VF and 175°C operating range maintain efficiency and reliability across engine bay temperature extremes. | Use Scenario: Reverse polarity protection at main AC/DC adapter input or PoE-powered equipment front-end. IC Role / Device Role / Timing Role: Blocking diode preventing damage from accidental negative supply connection or backfeed from downstream capacitors. Use Value: 1 µA leakage at 100 V ensures negligible standby current draw while maintaining fail-safe isolation. |
| Telecom Base Station Power | LED Driver Secondary Side |
Use Scenario: OR-ing function in redundant 48 V telecom rectifier outputs to prevent backfeeding and ensure fault containment. IC Role / Device Role / Timing Role: High-current, low-loss OR-ing diode placed between parallel power modules and shared output bus. Use Value: 50 A IFSM withstands inrush surges during hot-plug insertion; 7 °C/W RθJS supports forced-air-cooled board layouts. | Use Scenario: Output rectification in isolated LED driver flyback circuits powering streetlight or architectural lighting arrays. IC Role / Device Role / Timing Role: Secondary-side freewheeling diode converting transformer AC output to regulated DC for constant-current LED strings. Use Value: 9 ns tRR minimizes switching loss and EMI generation at 65–100 kHz switching frequencies typical in LED drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB2100-E3/54 (Vishay) | Same 100 V / 2 A rating but TO-277 package; 0.92 V VF max at 2 A; no AEC-Q101 qualification. | Lacks automotive qualification and has higher thermal resistance (RθJA ≈ 150 °C/W vs. 125 °C/W). | Select when cost sensitivity outweighs automotive compliance and thermal performance requirements. |
| SS210H (ON Semiconductor) | PowerDI123 package, AEC-Q101 qualified, but 0.95 V VF max at 2 A and 5 µA IR at 100 V. | Higher leakage limits use in ultra-low-power standby circuits; slightly lower surge rating (40 A). | Prefer where footprint compatibility is critical but marginally higher VF and leakage are acceptable. |
Compared with SB2100-E3/54 and SS210H, the DFLS2100Q-7 delivers the lowest forward voltage among AEC-Q101-qualified 2 A Schottkys in PowerDI123, enabling highest efficiency in thermally constrained automotive and industrial power stages.

FAQ
Is the DFLS2100Q-7 suitable for automotive applications?
Yes - it is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. Its -55°C to +175°C operating range, 50 A surge rating, and low high-temperature leakage make it appropriate for under-hood and ADAS power systems.
What is the recommended PCB layout for thermal performance?
Use the Diodes-recommended PowerDI123 pad layout with ≥2 oz copper on the cathode tab area. A minimum 2.6 mm × 3.5 mm thermal pad connected to internal ground planes reduces RθJA to 125 °C/W and enables full 2.0 A current handling at +70°C ambient.
Does the DFLS2100Q-7 have a built-in guard ring or edge termination?
No - the datasheet does not specify guard ring or field plate structures. Its 100 V VRRM is achieved through planar epitaxial Schottky junction design and optimized metal-semiconductor interface, validated per AEC-Q101 stress tests.
Can the DFLS2100Q-7 replace standard PN junction rectifiers in existing designs?
Yes - with careful attention to reverse voltage margin: its 100 V VRRM matches common 1N5822 replacements, but its lower VF reduces conduction loss by ~25% versus 1N5822 (1.1 V typ). Ensure layout accommodates PowerDI123 footprint and thermal pad requirements.
