Product details
Overview
B160B-13-F from Diodes Incorporated is a 60 V, 1.0 A surface-mount Schottky barrier rectifier in SMB package, with 0.7 V forward voltage at 1.0 A and 0.5 mA reverse leakage at rated VR and +25°C, optimized for low-voltage, high-frequency free-wheeling and polarity protection in DC/DC converters.
For engineers reviewing the B160B-13-F datasheet, B160B-13-F pinout, B160B-13-F application, or B160B-13-F equivalent, key selection criteria include its 60 V reverse blocking capability, low VF for reduced conduction loss, 30 A non-repetitive surge rating, RoHS-compliant matte tin plating, and SMB thermal performance (RθJT = 20 °C/W).
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient robustness and suppress edge breakdown, enabling reliable operation under repetitive voltage spikes in switching power supplies. Its low junction-to-terminal thermal resistance (20 °C/W) supports sustained 1.0 A average current at terminal temperatures up to +130°C when mounted on 5.0 mm² copper pads.
The device exhibits 110 pF typical junction capacitance at 4 V reverse bias and 1 MHz, making it suitable for high-frequency rectification where capacitive loading must be minimized. Reverse leakage remains ≤0.5 mA at 60 V and +25°C, rising to ≤10 mA at +100°C - a critical parameter for standby power integrity in always-on systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage; defines safe DC blocking limit in polarity protection and flyback clamp circuits. |
| IO | 1.0 A - Average rectified output current at TT = +130°C; sets continuous power handling in 12 V/24 V DC/DC outputs. |
| VF Max | 0.7 V @ IF = 1.0 A - Forward voltage drop; determines conduction loss (0.7 W at 1 A), directly impacting efficiency in low-VIN buck stages. |
| IR Max | 0.5 mA @ VR = 60 V, TA = +25°C - Reverse leakage; constrains quiescent current in battery-backed or energy-harvesting hold-up paths. |
| IFSM | 30 A - Non-repetitive peak forward surge current (8.3 ms half-sine); enables survival during inrush or short-circuit events in motor drive freewheeling. |
| CT | 110 pF @ VR = 4 V, f = 1 MHz - Junction capacitance; limits high-frequency switching noise and EMI generation in >100 kHz SMPS designs. |
| RθJT | 20 °C/W - Thermal resistance junction-to-terminal; confirms need for ≥5 mm² copper pad for full 1.0 A rating without derating. |
Pinout & Package
Package: SMB (Surface-Mount Small Outline Diode), molded plastic body with UL 94V-0 flammability rating, cathode indicated by band or notch, lead-free matte tin plating per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node in buck converter); must route with low-inductance trace to minimize ringing. |
| Cathode | Forward current exit / reverse blocking terminal | Connected to higher-potential rail (e.g., output capacitor positive); cathode band orientation must match PCB silkscreen for automated assembly verification. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge avalanche and improves transient voltage immunity - essential for reliability in unregulated input rails with line surges. |
| Low forward voltage (0.7 V) | Reduces conduction loss by ~30% vs. comparable silicon diodes - directly increases efficiency in 5–24 V DC/DC converters operating at >1 A. |
| 30 A surge rating (8.3 ms) | Withstands inductive kickback from solenoids or relay coils without degradation - eliminates need for external snubbers in industrial control I/O modules. |
| RoHS-compliant, halogen-free | Meets IPC-1752A material declaration requirements and EU Directive 2015/863/EU - supports compliance documentation for medical and industrial end equipment. |
Applications
| DC/DC Converter Freewheeling | Polarity Protection |
|---|---|
Use Scenario: Freewheeling path in synchronous buck converter output stage, clamping inductive energy during high-side FET off-time. IC Role / Device Role / Timing Role: Passive rectifier providing low-loss return path for inductor current; operates continuously at switching frequency (100 kHz–2 MHz). Use Value: 0.7 V VF minimizes power dissipation versus silicon alternatives, improving thermal margin in compact 12 V → 3.3 V point-of-load designs. |
Use Scenario: Reverse-voltage protection at main power input of embedded controller board powered from external 12 V adapter. IC Role / Device Role / Timing Role: Series-blocking diode preventing damage during accidental reverse connection; conducts only during normal operation. Use Value: 60 V VRRM provides 2× safety margin over 12 V nominal input, while 0.5 mA IR ensures <1 µW standby loss in battery-backed systems. |
| Motor Drive Recirculation | Low-Voltage Inverter Output |
Use Scenario: Recirculating current path across brushed DC motor terminals during PWM braking or direction reversal. IC Role / Device Role / Timing Role: Clamp diode absorbing back-EMF spikes; subjected to repetitive 30 A surge pulses synchronized with PWM edges. Use Value: 30 A IFSM rating matches typical motor stall currents, eliminating thermal runaway risk during frequent direction changes. |
Use Scenario: Output rectification in 24 V AC-to-DC inverter feeding LED lighting or small appliance loads. IC Role / Device Role / Timing Role: High-frequency rectifier converting 20–100 kHz square-wave AC to DC; operates with minimal capacitive loading. Use Value: 110 pF CT limits displacement current and EMI generation, easing EMC filter design compared to higher-CT alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS16-E3/5AT (Vishay) | Same SMB package, 60 V VRRM, but 0.75 V VF @ 1 A and 1.0 mA IR @ 60 V/+25°C. | Higher leakage may increase standby loss in battery-powered devices; slightly higher VF reduces efficiency in high-duty-cycle converters. | Select if Vishay supply chain alignment or legacy qualification is required; verify leakage impact in ultra-low-power sleep modes. |
| MBR160-TP (Micro Commercial Components) | SMB package, 60 V VRRM, 0.72 V VF @ 1 A, but RθJT = 25 °C/W and no guard ring construction specified. | Higher thermal resistance requires larger copper area for same current; absence of guard ring reduces surge tolerance in noisy industrial environments. | Prefer for cost-sensitive consumer applications with benign thermal and EMI conditions; avoid in automotive or factory automation. |
Compared with SS16-E3/5AT and MBR160-TP, B160B-13-F delivers superior thermal performance (20 °C/W), lower leakage (0.5 mA), and verified guard ring protection - making it optimal for space-constrained, high-reliability 12–24 V power rails demanding consistent efficiency and surge resilience.

FAQ
Is B160B-13-F suitable for automotive applications?
No - B160B-13-F is not AEC-Q101 qualified. Diodes Incorporated offers automotive-grade variants (e.g., B160BQ-13-F) with PPAP documentation, IATF 16949 manufacturing, and extended temperature validation. This part is rated for -65°C to +150°C operation but lacks automotive change control and stress test certification.
What is the recommended PCB pad layout for SMB package?
Per Diodes' DS13002 Rev. 20-2, use pad dimensions: length 6.80 mm, width 2.30 mm, solder mask opening matching copper, with 1.80 mm gap between pads. A 5.0 mm² (minimum) copper pour per terminal is required to achieve full 1.0 A current rating and maintain RθJT = 20 °C/W.
How does temperature affect reverse leakage in B160B-13-F?
Reverse leakage rises exponentially with temperature: maximum 0.5 mA at +25°C and rated 60 V, increasing to 10 mA at +100°C under same voltage. At +150°C, leakage may exceed 100 mA - necessitating thermal design that keeps junction below 125°C in high-ambient applications.
Can B160B-13-F replace B160-13-F in existing designs?
Yes - B160B-13-F (SMB) and B160-13-F (SMA) share identical electrical specs (60 V, 1.0 A, 0.7 V VF) but differ mechanically: SMB is larger (2.5 × 5.6 mm vs. 2.9 × 4.6 mm), has higher thermal mass, and requires different footprint. Layout redesign is mandatory; thermal performance improves with SMB's lower RθJT.
