Product details
Overview
B160S1F-7 from Diodes Incorporated is a 1.0A surface-mount Schottky barrier rectifier with 60V peak repetitive reverse voltage, 0.65V max forward voltage at 1A/25°C, 200µA max reverse leakage at 60V/25°C, and SOD123F package - used as a boost diode in DC-DC converters for portable power supplies.
For engineers reviewing the B160S1F-7 datasheet, B160S1F-7 pinout, B160S1F-7 application, or B160S1F-7 equivalent, key selection criteria include low VF for efficiency, high-temperature IR stability up to +150°C, SOD123F thermal resistance (RθJA = 100°C/W), and RoHS-compliant matte tin terminals.
Technical Context
This Schottky rectifier uses a planar epitaxial construction to achieve low forward voltage drop and minimized reverse recovery charge. Its junction capacitance is 45pF at 4V/1MHz, enabling fast switching in high-frequency DC-DC topologies.
The device operates across –55°C to +150°C with thermal resistance junction-to-ambient of 100°C/W on standard FR-4 PCBs. Reverse leakage remains under 0.2mA at 60V and +125°C, supporting stable blocking in thermally stressed environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum non-repetitive reverse voltage the device blocks reliably in boost or flyback configurations |
| IO | 1.0 A - Continuous DC forward current rating at +25°C ambient, derated to ~0.4A at +100°C per Figure 4 |
| VF (max) | 0.65 V @ 1A, 25°C - Enables <0.65W conduction loss per diode in 1A paths, reducing thermal load |
| IR (max) | 200 µA @ 60V, 25°C - Low leakage preserves efficiency in standby and light-load conditions |
| RθJA | 100 °C/W - Thermal performance on 0.4"×0.5" FR-4 board defines minimum copper area needed for thermal management |
| CT | 45 pF @ 4V, 1MHz - Junction capacitance impacts switching node ringing and EMI in >100kHz converters |
Pinout & Package
SOD123F surface-mount package: molded green plastic case (UL 94V-0), cathode band marking, matte tin-plated copper leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/source side in boost/flyback; polarity must align with cathode band orientation |
| Cathode | Forward current exit / reverse blocking terminal | Connected to switch node or output rail; cathode band identifies this terminal visually and on PCB silkscreen |
Key Features
| Feature | Design Value |
|---|---|
| Low VF (0.53V typ @ 1A/25°C) | Reduces conduction loss by ~30% vs. comparable 1A silicon rectifiers, improving converter efficiency |
| High-temp IR stability (0.2mA max @ 60V/125°C) | Prevents thermal runaway in enclosed or high-ambient environments such as automotive cabin modules |
| SOD123F footprint | Enables compact layout in space-constrained applications like USB-C PD adapters and IoT power stages |
| Lead-free, halogen- and antimony-free | Meets RoHS 3 (2015/863/EU) and JEDEC MSL Level 1 requirements without reflow compatibility penalties |
Applications
| Boost Diode in DC-DC Converters | Blocking Diode in Solar Charge Controllers |
|---|---|
Use Scenario: Step-up conversion from 3.7V Li-ion battery to 5V/9V/12V USB-PD output rails. IC Role / Device Role / Timing Role: Unidirectional current path during MOSFET off-time; conducts inductor energy transfer to output capacitor.

IC Role / Device Role / Timing Role: Reverse-blocking element placed between PV array and battery terminal. Use Value: 200µA IR at 25°C ensures negligible nighttime battery drain; <0.2mA at 85°C maintains >99.9% daily retention. |
| Recirculating Diode in Motor Drivers | Output Rectifier in AC-DC Adapters |
Use Scenario: Freewheeling path for brushed DC motor current when H-bridge low-side FETs turn off. IC Role / Device Role / Timing Role: Provides low-loss return path for inductive kickback, clamping voltage spike. Use Value: 30A IFSM rating handles transient surge currents during motor stall or direction reversal. | Use Scenario: Secondary-side rectification in 5–20W wall adapters using quasi-resonant flyback topology. IC Role / Device Role / Timing Role: Converts transformer secondary AC to regulated DC output. Use Value: 45pF CT minimizes switching node oscillation, easing EMI filter design and passing CISPR-32 Class B. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB160-E3/54 (Vishay) | Same 60V/1A rating; VF = 0.72V max @ 1A/25°C; SOD123 package (not SOD123F) | Higher VF increases conduction loss by ~100mW at 1A; slightly larger thermal pad clearance required | Select if legacy SOD123 footprint compatibility is mandatory and 0.07V VF penalty is acceptable |
| SS16 (ON Semiconductor) | 60V/1A; VF = 0.75V max @ 1A/25°C; SOD123 package; IR = 500µA @ 60V/25°C | Doubles leakage vs. B160S1F-7, limiting use in high-temp or ultra-low-power standby designs | Choose only for cost-sensitive, non-thermally constrained consumer applications below 60°C ambient |
Compared with SB160-E3/54 and SS16, the B160S1F-7 delivers the lowest VF and best high-temperature IR performance in the SOD123F footprint, making it optimal for thermally dense, efficiency-critical DC-DC stages where thermal resistance and leakage directly impact system reliability.

FAQ
What is the maximum junction temperature for continuous operation of the B160S1F-7?
The B160S1F-7 has an operating junction temperature range of –55°C to +150°C. It sustains continuous conduction at +150°C provided thermal design meets RθJA = 100°C/W on specified FR-4 PCB layout, and peak surge current does not exceed 30A for 8.3ms half-sine wave.
Does the B160S1F-7 require derating for capacitive loads?
Yes - the datasheet specifies that for capacitive loads, the average forward current IO must be derated by 20%. This accounts for higher RMS current and peak stress caused by inrush into large output capacitors, preventing thermal overload during startup or load transients.
Is the SOD123F package compatible with standard SOD123 reflow profiles?
Yes - the SOD123F package uses the same footprint and thermal mass as standard SOD123, and its matte tin finish is fully compatible with IPC/JEDEC J-STD-020 moisture-sensitive level 1 reflow profiles, including peak temperatures up to 260°C.
How does the B160S1F-7's reverse leakage compare to silicon rectifiers at elevated temperature?
At +125°C and 60V reverse bias, B160S1F-7 exhibits ≤0.2mA IR - significantly lower than typical 1A silicon rectifiers (>5mA under same conditions). This enables stable blocking in high-ambient applications where silicon devices risk thermal runaway.
