Product details
Overview
B260S1F-7 from Diodes Incorporated is a 2.0A, 60V Schottky barrier rectifier in SOD123F package, featuring 0.65V max forward voltage at 2A/25°C, 0.2mA max reverse leakage at 60V/25°C, and thermal resistance of 100°C/W (junction-to-ambient), optimized for boost, blocking, and recirculating diode roles in DC-DC converters and power supplies.
For engineers reviewing the B260S1F-7 datasheet, B260S1F-7 pinout, B260S1F-7 application, or B260S1F-7 equivalent, key selection criteria include low VF for efficiency, high-temperature IR stability up to +150°C, RoHS-compliant matte tin terminals, SOD123F footprint compatibility, and 50A non-repetitive surge rating for transient robustness.
Technical Context
This Schottky rectifier uses a planar metal-semiconductor junction to achieve low forward conduction loss and fast switching with no minority-carrier storage delay. Its 75pF typical junction capacitance at 4V/1MHz supports high-frequency operation in SMPS topologies.
The device operates across –55°C to +150°C with derated current above +25°C (e.g., ~1.3A at +100°C), and its 50°C/W junction-to-case thermal resistance enables effective heat transfer when mounted on copper pads per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in boost/buck output stages. |
| IO | 2 A - Average rectified current at TA = +25°C; defines continuous conduction capability in low-power SMPS. |
| VF (max) | 0.65 V @ 2A, +25°C - Low forward drop reduces conduction loss and improves system efficiency by ~0.5W vs. silicon diodes. |
| IR (max) | 0.2 mA @ 60V, +25°C - Tight leakage spec ensures minimal standby power loss and thermal stability under bias. |
| RθJA | 100 °C/W - Thermal resistance determines junction temperature rise; requires ≥0.2"×0.25" copper pad for rated IO. |
| IFSM | 50 A - Non-repetitive surge rating allows survival of inrush or fault currents in 8.3ms half-sine events. |
| TJ Range | –55°C to +150°C - Wide operating range supports automotive under-hood and industrial ambient conditions. |
Pinout & Package
SOD123F surface-mount package: 2-terminal, cathode-banded, molded green plastic case (UL 94V-0), 0.015g weight, 1.80mm width (D), 2.70mm length (E), 3.50mm height (He).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential node (e.g., switch node in boost); must handle full IO and IFSM. |
| Cathode (banded) | Current exit point during forward conduction | Connected to higher-potential node (e.g., output rail); polarity marking critical for PCB assembly. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high current | 0.52V typ @ 2A/+125°C - Enables cooler operation and >95% efficiency in 5–24V DC-DC outputs. |
| Stable high-temp IR | 14mA max @ 60V/+125°C - Prevents thermal runaway in enclosed or high-ambient environments. |
| RoHS & Green compliant | Br/Cl <900ppm, Sb <1000ppm, Pb-free - Meets EU environmental directives and OEM sustainability requirements. |
| SOD123F footprint | Standardized 2-pin SMT outline with 0.2"×0.25" pad recommendation - Ensures manufacturability and reflow compatibility. |
Applications
| Boost Diode in DC-DC Converters | Blocking Diode in Solar Charge Controllers |
|---|---|
Use Scenario: Used in step-up converter output stage to isolate input from output while conducting inductor current. IC Role / Device Role / Timing Role: Unidirectional power path enabler; conducts only during switch-off phase with minimal voltage drop. Use Value: 0.65V VF reduces power loss by 1.3W at 2A, lowering thermal stress on adjacent MOSFETs and inductors. | Use Scenario: Placed between PV panel and battery to prevent reverse discharge at night or low-light conditions. IC Role / Device Role / Timing Role: Reverse-current blocker; remains reverse-biased except during daylight charging cycles. Use Value: 0.2mA IR at 25°C and 14mA at 125°C ensures <10mW standby loss even in hot rooftop installations. |
| Recirculating Diode in Motor Drivers | Output Rectifier in AC-DC Adapters |
Use Scenario: Freewheeling path for inductive kickback when H-bridge MOSFETs turn off during PWM control. IC Role / Device Role / Timing Role: Fast recovery path for stored inductor energy; zero recovery time eliminates switching spikes. Use Value: Schottky architecture avoids minority-carrier tail current, reducing EMI and enabling 500kHz+ PWM frequencies. | Use Scenario: Secondary-side rectification in 5–12V wall adapters using flyback or forward topology. IC Role / Device Role / Timing Role: High-efficiency output rectifier; handles continuous 2A load with low conduction loss. Use Value: 100°C/W RθJA allows direct mounting on PCB without heatsink in ≤5W adapter designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS26 (Microchip) | Same 60V/2A rating, but VF = 0.75V max @ 2A/25°C; RθJA = 120°C/W | Higher conduction loss and thermal resistance reduce efficiency in space-constrained layouts | Prefer B260S1F-7 where board area or thermal margin is limited |
| SB260 (ON Semiconductor) | Identical electrical specs, but SOD123 (not SOD123F) package; 0.1mm taller case height | Slight footprint mismatch may require pad revision; same thermal performance | Acceptable if existing SOD123 land pattern is used and height clearance permits |
Compared with SS26 and SB260, B260S1F-7 delivers the lowest VF (0.65V) and best thermal resistance (100°C/W) in its class, making it optimal for thermally dense 2A DC-DC outputs where efficiency and reliability at elevated temperatures are prioritized.

FAQ
What is the maximum junction temperature for continuous operation?
The B260S1F-7 has an absolute maximum junction temperature of +150°C. Continuous operation at this limit requires strict thermal design: 0.2" × 0.25" copper pad, ambient ≤+75°C, and derated current per Figure 4 - e.g., 1.0A at +100°C ambient. Exceeding TJ(max) risks parametric shift and premature failure.
Is the SOD123F package compatible with standard SOD123 reflow profiles?
Yes - the SOD123F package uses the same leadframe geometry and solderable matte tin finish as SOD123, and complies with IPC/JEDEC J-STD-020 moisture sensitivity Level 1. Standard lead-free reflow profiles (peak 260°C, 60s above 217°C) are fully supported without modification.
How does reverse leakage behave at elevated temperatures?
IR increases predictably with temperature: 0.02mA typ at +25°C, 14mA max at +125°C, and ≤0.2mA at +25°C per datasheet limits. This controlled rise - unlike thermal runaway in silicon diodes - enables reliable operation in automotive and industrial enclosures up to +105°C ambient.
Can B260S1F-7 replace a 1N5819 in existing designs?
Yes, with qualification: both are 3A-rated Schottkys, but B260S1F-7 is 2A-rated, smaller (SOD123F vs. DO-41), and has lower VF (0.65V vs. 0.475V typ). It fits SOD123 footprints, not through-hole; verify current demand, thermal margin, and layout compatibility before substitution.
