Product details
Overview
DFLS2100-7 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 delivers low conduction loss and stable high-temperature operation, used as boost diodes in DC-DC converters, reverse polarity protection in 12 V/24 V automotive power supplies, and blocking diodes in solar charge controllers.
For engineers reviewing the DFLS2100-7 datasheet, DFLS2100-7 pinout, DFLS2100-7 application, or DFLS2100-7 equivalent, key selection criteria include forward voltage at rated current, thermal resistance (7 °C/W junction-to-solder), surge capability (50 A IFSM), high-temperature leakage behavior, and PowerDI123 footprint compatibility with FR-4 PCB layouts.
Technical Context
This Schottky rectifier uses a planar metal–semiconductor junction optimized for low VF and minimal temperature-dependent IR drift. Its patented interlocking clip design enhances mechanical robustness and enables 50 A non-repetitive surge current handling without bond wire failure.
Thermal performance is defined by RθJS = 7 °C/W (junction-to-solder) and RθJA = 125 °C/W (junction-to-ambient on standard FR-4), supporting continuous operation up to +175 °C junction temperature with appropriate board copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; sets usable input range in 48 V industrial or 36 V automotive systems. |
| IO | 2.0 A - Average rectified output current at TA = +25°C; derated to ~1.6 A at +100°C per Fig. 5. |
| VF (max) | 0.86 V @ 2.0 A - Directly determines conduction loss (1.72 W at full load); lower than comparable 100 V Si diodes (~1.1 V). |
| IR (max) | 1 µA @ 100 V - Enables low standby power in always-on circuits; remains <10 µA up to +125°C per datasheet curves. |
| IFSM | 50 A - Withstands single half-sine surge (8.3 ms); supports inrush limiting in offline SMPS inputs. |
| RθJS | 7 °C/W - Junction-to-solder thermal resistance; allows direct thermal path to PCB copper pour for efficient heat extraction. |
| CT | 36 pF @ 5 V - Low junction capacitance minimizes switching noise and EMI in high-frequency rectification (e.g., 300 kHz boost stages). |
Pinout & Package
Package: PowerDI®123 - surface-mount, 2-terminal plastic package with exposed cathode tab for thermal and electrical connection. Dimensions: 3.70 mm × 1.78 mm × 1.00 mm (L × W × H); weight ≈ 0.01 g; UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to input/source side (e.g., switch node in boost converter); no marking; electrically tied to leadframe inner portion. |
| Cathode | Current exit point during forward conduction; reverse-blocking terminal | Marked with cathode band; soldered to PCB copper pad for thermal dissipation and circuit return path; forms primary thermal interface. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at rated current | 0.86 V max @ 2.0 A reduces conduction loss by >30% vs. standard PN diodes, improving efficiency in 12–48 V DC-DC stages. |
| High-temperature IR stability | Leakage stays <10 µA up to +125°C, preventing thermal runaway in enclosed automotive or industrial enclosures. |
| Patented interlocking clip | Enables 50 A surge rating without wire-bond fatigue-critical for hot-plug or load-dump tolerant designs. |
| Green, RoHS-compliant construction | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb); matte tin annealed finish ensures MIL-STD-202 solderability. |
Applications
| Boost Diode in DC-DC Converters | Reverse Polarity Protection |
|---|---|
Use Scenario: Used in the boost stage of a 12 V to 48 V telecom power module operating at 250 kHz switching frequency. IC Role / Device Role / Timing Role: Rectifies switched inductor current; conducts only during off-time; no timing function but defines minimum duty cycle via VF drop. Use Value: 0.86 V VF limits power loss to ≤1.72 W at 2 A, enabling compact heatsinkless design within 75°C ambient. | Use Scenario: Placed in series with battery input of an ADAS camera ECU to block damage from accidental reverse connection. IC Role / Device Role / Timing Role: Unidirectional current valve; blocks reverse current flow while passing forward load current up to 2 A continuously. Use Value: 1 µA IR at 100 V ensures <1 µW standby loss; 175°C TJ rating supports under-hood deployment. |
| Blocking Diode in Solar Charge Controllers | OR-ing Diode in Dual-Supply Systems |
Use Scenario: Prevents nighttime battery discharge through PV panel strings in a 24 V off-grid solar controller. IC Role / Device Role / Timing Role: Blocks reverse current path from battery to panel; operates in steady-state DC blocking mode. Use Value: 100 V VRRM accommodates open-circuit PV voltages up to 80 V; low VF avoids unnecessary voltage drop in charging path. | Use Scenario: Enables seamless switchover between main 24 V supply and backup battery in industrial PLC I/O modules. IC Role / Device Role / Timing Role: Passive OR-ing element; conducts from higher-voltage source while blocking lower-voltage source. Use Value: Low VF minimizes voltage differential between sources, reducing cross-conduction risk and improving switchover speed. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS210H-TP (Micro Commercial) | Same 100 V/2 A rating; VF = 0.85 V @ 2 A; RθJA = 130 °C/W; no AEC-Q200 qualification. | Lacks automotive qualification and interlocking clip; lower surge rating (30 A IFSM). | Acceptable for cost-sensitive industrial use where AEC-Q200 compliance is not required. |
| SB2100-E3/52 (Vishay) | 100 V/2 A; VF = 0.82 V @ 2 A; RθJA = 120 °C/W; DO-214AA package (larger footprint, higher RθJA). | DO-214AA requires more PCB area; lacks PowerDI123's low-profile advantage and 7 °C/W RθJS. | Preferred when legacy DO-214AA layout exists; avoid if space or thermal performance is critical. |
Compared with SS210H-TP and SB2100-E3/52, DFLS2100-7 uniquely combines AEC-Q200 readiness, 50 A surge capability, and 7 °C/W RθJS in a 3.7 mm × 1.8 mm footprint-making it optimal for thermally constrained, high-reliability automotive and industrial rectification.

FAQ
What is the maximum junction temperature rating for DFLS2100-7?
The DFLS2100-7 is rated for continuous operation from –55°C to +175°C junction temperature. This rating is validated per JEDEC standards and supported by its low RθJS (7 °C/W) and stable high-temperature leakage (<10 µA at +125°C), making it suitable for under-hood automotive and high-ambient industrial environments.
Does DFLS2100-7 have automotive qualification?
Yes-the base DFLS2100-7 is qualified to AEC-Q200 standards for high-reliability applications. An automotive-specific variant, DFLS2100Q, is also available with additional PPAP documentation and extended temperature screening, but the -7 version meets core AEC-Q200 stress test requirements including temperature cycling and HTRB.
Can DFLS2100-7 replace a standard PN rectifier in existing designs?
Yes, provided reverse voltage and surge requirements are met. Its 100 V VRRM and 50 A IFSM exceed many 1N5822-class diodes. However, designers must verify that the lower VF does not cause control loop instability in voltage-mode SMPS, and that layout accommodates the PowerDI123 footprint and thermal pad requirements.
What is the recommended PCB pad layout for thermal performance?
Diodes specifies a minimum 2 oz. copper pad layout for the cathode tab, with dimensions matching the PowerDI123 outline (E = 3.70 mm, E1 = 2.80 mm). The recommended pad extends beyond the package edges to maximize thermal conduction; exact dimensions and thermal vias guidance are published in Diodes' package outline document #AP02004.
