Product details
Overview
B160AF-13 from Diodes Incorporated is a 60 V, 1 A surface-mount Schottky barrier rectifier in SMAF package, featuring 0.65 V max forward voltage at 1 A and 0.20 mA max reverse leakage at 60 V/25°C, optimized for boost, blocking, and recirculating diode roles in DC-DC converters and power supplies.
For engineers reviewing the B160AF-13 datasheet, B160AF-13 pinout, B160AF-13 application, or B160AF-13 equivalent, this device is selected for low VF, high-temperature IR stability, RoHS-compliant lead-free finish, and compact SMAF footprint in space-constrained power rectification designs.
Technical Context
This Schottky rectifier uses a platinum-silicide or similar low-barrier metal-semiconductor junction to achieve low forward voltage drop and fast switching with no minority-carrier storage delay. Its thermal resistance (RθJA = 95 °C/W) and operating range (–55 °C to +150 °C) support reliable operation in thermally demanding environments.
The device exhibits 45 pF typical junction capacitance at 4.0 V reverse bias and 1 MHz, enabling efficient high-frequency rectification. Reverse leakage remains tightly controlled-0.20 mA at 60 V/25°C and 7.5 mA at 60 V/125°C-reducing thermal runaway risk in elevated ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for circuit blocking capability |
| IO | 1 A - Continuous average forward current rating; defines steady-state power handling under thermal derating |
| VF (max) | 0.65 V @ 1 A, 25°C - Low conduction loss improves efficiency and reduces heat generation in rectifier paths |
| IR (max) | 0.20 mA @ 60 V, 25°C - Tight reverse leakage ensures stable performance in high-temperature bias conditions |
| RθJA | 95 °C/W - Thermal resistance from junction to ambient on standard FR-4 PCB; informs heatsinking requirements |
| CT | 45 pF @ 4 V, 1 MHz - Junction capacitance impacts high-frequency switching loss and EMI behavior |
| TJ Range | –55 °C to +150 °C - Wide operating temperature enables use in automotive under-hood and industrial control environments |
Pinout & Package
Package: SMAF (Surface Mount Axial Flat), molded plastic case with matte tin–annealed copper leadframe, UL 94V-0 rated, 0.036 g weight, cathode band polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of rectifier path; accepts input during conduction phase |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; connects to output/load side; sustains 60 V reverse bias without significant leakage |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.65 V max at 1 A/25°C - directly reduces I²R losses and improves system efficiency by ~3–5% vs. standard PN rectifiers |
| High-temperature IR stability | 7.5 mA max at 60 V/125°C - maintains safe thermal margin in hot environments without runaway failure |
| RoHS-compliant lead finish | Matte tin annealed over copper - ensures reliable solderability and compliance with EU environmental directives |
| Green compound packaging | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) - meets stringent environmental standards for industrial and consumer goods |
Applications
| Boost Diode | Blocking Diode |
|---|---|
Use Scenario: Used in step-up DC-DC converter output stage to prevent backflow from output capacitor into inductor during switch-off phase. IC Role / Device Role / Timing Role: Unidirectional current valve enabling energy transfer timing control in synchronous/non-synchronous topologies. Use Value: 0.65 V VF minimizes conduction loss during high-duty-cycle operation, preserving conversion efficiency above 90% at 1 A load. | Use Scenario: Placed between battery and system rail to isolate backup source from main supply during normal operation. IC Role / Device Role / Timing Role: Reverse-biased isolation element preventing cross-conduction and enabling seamless source switchover. Use Value: 0.20 mA IR at 25°C and 7.5 mA at 125°C ensures minimal standby drain, extending battery life in always-on embedded systems. |
| Recirculating Diode | Input Rectifier |
Use Scenario: Connected across inductive load (e.g., solenoid, relay coil) to clamp flyback voltage during de-energization. IC Role / Device Role / Timing Role: Fast-recovery freewheeling path absorbing stored magnetic energy within nanosecond-scale turn-on. Use Value: Zero minority-carrier storage enables sub-10 ns turn-on, suppressing voltage spikes beyond 60 V and protecting driving MOSFETs. | Use Scenario: Front-end rectifier in low-power AC-DC adapters or auxiliary power supplies feeding 3.3 V/5 V rails. IC Role / Device Role / Timing Role: Half-wave rectifier converting transformer secondary AC to pulsating DC prior to filtering and regulation. Use Value: SMAF footprint (2.25–2.95 mm × 3.95–4.60 mm) supports high-density layout while maintaining 1 A IO rating in compact wall adapters. |
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 60 V VRRM, 1 A IO, but VF = 0.72 V max @ 1 A; RθJA = 100 °C/W | Higher conduction loss and slightly worse thermal performance reduce efficiency in high-ambient designs | Acceptable where cost sensitivity outweighs 70 mV VF penalty and board-level thermal margin exceeds 10 °C |
| SS16 (ON Semiconductor) | 60 V VRRM, 1 A IO, VF = 0.75 V max @ 1 A; IR = 0.5 mA @ 60 V/25°C | Triple the reverse leakage limits usable temperature ceiling in sealed enclosures above 85 °C | Preferred only when legacy SS16 footprint compatibility is mandatory and thermal design accommodates higher IR drift |
Compared with SB160-E3/54 and SS16, B160AF-13 delivers superior forward voltage and reverse leakage control-critical for efficiency-sensitive, high-temperature power stages-while maintaining identical SMAF mounting and RoHS/Green compliance.

FAQ
What is the maximum junction temperature for continuous operation of B160AF-13?
The B160AF-13 has a specified operating junction temperature range of –55 °C to +150 °C. Continuous operation at +150 °C is permitted provided the device's thermal design ensures actual TJ does not exceed this limit under worst-case ambient and power dissipation conditions, per its RθJA = 95 °C/W rating on standard FR-4.
Is B160AF-13 suitable for use in automotive applications?
Yes-B160AF-13 meets AEC-Q200 stress test guidelines for passive components and operates reliably from –40 °C to +125 °C (with full specification guaranteed to +150 °C). Its low IR and stable VF make it appropriate for engine control unit auxiliary supplies and infotainment power rails.
Does B160AF-13 have a built-in guard ring or edge termination?
No-the B160AF-13 datasheet does not specify guard ring or field plate structures. Its reverse voltage capability relies on planar junction design and process-controlled doping profiles, validated by 60 V VRRM rating and leakage performance up to 125 °C.
Can B160AF-13 replace B150AF-13 in existing designs?
Yes-with caution. Both share identical SMAF package, pinout, and thermal specs, but B160AF-13 has higher VRRM (60 V vs. 50 V) and higher IR (0.20 mA vs. 0.10 mA at 25°C). It is a direct upgrade where 60 V blocking is needed, but verify reverse bias margin and thermal impact in high-leakage-sensitive circuits.
