Product details
Overview
B260S1FX-7 from Diodes Incorporated is a 2A, 60V Trench Schottky barrier rectifier in SOD123F package, optimized for low forward voltage (0.60 V max at 2 A, 25°C) and low leakage (200 µA max at 60 V, 25°C), enabling high-efficiency DC-DC converters and freewheeling paths in compact power supplies.
For engineers reviewing the B260S1FX-7 datasheet, B260S1FX-7 pinout, B260S1FX-7 application, or B260S1FX-7 equivalent, key selection criteria include its 150°C junction rating, soft fast switching behavior, RoHS-compliant matte tin terminals, and SOD123F footprint compatibility with space-constrained board layouts.
Technical Context
This Schottky diode uses trench-based silicon structure to reduce forward voltage drop while maintaining low reverse leakage-critical for minimizing conduction loss in high-frequency switching topologies. Its thermal resistance (RθJA = 115°C/W on FR-4) and 150°C maximum junction temperature support operation in thermally demanding environments without forced cooling.
The device exhibits soft reverse recovery and minimal stored charge, reducing EMI in buck converters and flyback snubbers. Polarity is defined by a cathode band; no gate or control logic is involved-it operates as a passive unidirectional current path with zero turn-on delay.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - blocks up to 60 V reverse bias without breakdown, suitable for 24 V and 48 V system rails. |
| IO | 2 A continuous - delivers rated DC output current with derating above 75°C case temperature. |
| VF Max | 0.60 V at 2 A, 25°C - reduces conduction loss to ≤1.2 W per diode in high-current paths. |
| IR Max | 200 µA at 60 V, 25°C - ensures minimal standby power loss in reverse-biased blocking applications. |
| TJ Max | +150°C - enables reliable operation in under-hood automotive or sealed industrial enclosures. |
| Package | SOD123F - surface-mount, 2-pin, 1.8 mm × 2.7 mm footprint with 0.015 g mass and UL 94V-0 molding compound. |
Pinout & Package
Package: SOD123F - molded plastic, halogen- and antimony-free "Green" compound, moisture sensitivity level 1, matte tin-plated copper leadframe, cathode band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential node (e.g., switch node in buck converter); no internal series resistance specification provided. |
| Cathode | Current exit point during forward conduction; marked with band | Connected to higher-potential rail (e.g., output capacitor positive); defines polarity for reverse-blocking function. |
Key Features
| Feature | Design Value |
|---|---|
| Soft, fast switching | Low stored charge and negligible reverse recovery time minimize switching loss and EMI in >100 kHz DC-DC stages. |
| +150°C operating junction temperature | Enables use in sealed enclosures or near heat sources without thermal shutdown or parameter drift. |
| Lead-free, RoHS-compliant finish | Matte tin over copper meets JEDEC J-STD-020 solderability requirements and eliminates Pb-related reliability concerns. |
| Low leakage at elevated temperature | 20 µA max at 60 V, 100°C - maintains blocking integrity in hot ambient conditions (e.g., industrial motor drives). |
Applications
| SMPS Output Rectification | DC-DC Converter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 3.3–12 V at up to 2 A. IC Role / Device Role / Timing Role: Unidirectional current path replacing synchronous MOSFETs where simplicity and cost outweigh efficiency gains. Use Value: 0.60 V VF limits conduction loss to 1.2 W, reducing heatsink requirement versus standard PN diodes. | Use Scenario: Freewheeling path across inductive loads in non-isolated buck regulators powering FPGAs or microcontrollers. IC Role / Device Role / Timing Role: Provides low-loss return path for inductor current during high-side switch off-time. Use Value: Soft recovery avoids voltage spikes that could trigger false overvoltage protection in sensitive downstream ICs. |
| AC-DC Adapter Output Stage | Reverse Polarity Protection |
Use Scenario: Output rectification in compact wall adapters converting 100–240 V AC to 5–12 V DC for consumer electronics. IC Role / Device Role / Timing Role: Converts transformer secondary AC to regulated DC; placed after filtering capacitor. Use Value: Low VF improves adapter efficiency to meet Level VI standards without increasing size or cost. | Use Scenario: Input protection in battery-powered devices (e.g., portable test equipment) powered via barrel jack or USB-C. IC Role / Device Role / Timing Role: Anode tied to input connector, cathode to system rail; blocks reverse current if supply is connected backward. Use Value: 200 µA leakage at 25°C ensures <1 µW standby loss-critical for multi-year battery life in IoT sensors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS26-E3/57T (Vishay) | Same 60 V VRRM, 2 A IO, but VF = 0.75 V max at 2 A - 25% higher conduction loss. | Less suitable for thermally constrained 12 V output rails where 0.15 V delta increases junction temperature rise. | Select only if SOD123F footprint compatibility is not required and cost is primary driver. |
| MBR260T3G (ON Semiconductor) | Higher 60 V rating but TO-220AC package - 3× larger footprint and 10× higher thermal mass. | Requires PCB redesign and heatsinking; unsuitable for space-limited portable designs. | Prefer when >3 A surge capability (IFSM = 50 A) or legacy through-hole assembly is mandated. |
Compared with SS26-E3/57T and MBR260T3G, B260S1FX-7 delivers lowest forward voltage in the smallest SOD123F package, making it optimal for high-density, thermally sensitive 2 A DC-DC outputs where efficiency and board area are prioritized.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The B260S1FX-7 has a specified maximum junction temperature of +150°C. This rating is validated under conditions of 2 A DC forward current and ambient thermal management per the datasheet's FR-4 mounting condition. Operation beyond this temperature risks irreversible degradation of the Schottky barrier and increased leakage current.
Is the SOD123F package compatible with reflow soldering per JEDEC J-STD-020?
Yes-the SOD123F package is rated for moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260°C). The matte tin finish on the copper leadframe meets MIL-STD-202 Method 208 solderability requirements, and the UL 94V-0 molding compound withstands repeated thermal cycling without delamination.
Does this diode require a heatsink in a 2 A, 12 V DC-DC application?
No heatsink is required for 2 A continuous operation at ambient temperatures ≤55°C when mounted on a 0.4" × 0.5", 2 oz copper pad on FR-4. At 75°C ambient, derating to ~1.5 A is recommended per Figure 3. Thermal simulation using RθJA = 115°C/W confirms junction temperature remains below 150°C under these conditions.
Can B260S1FX-7 replace a standard PN rectifier like 1N4007 in a 24 V AC-DC adapter?
No-it is not a direct replacement due to lower 60 V VRRM versus 1N4007's 1000 V rating. In 24 V AC-DC adapters, peak reverse voltage is typically <40 V, so B260S1FX-7 is electrically suitable and offers superior efficiency, but layout must accommodate SOD123F instead of DO-41.
