Product details
Overview
B160AX-13 from Diodes Incorporated is a 1A, 60V Trench Schottky barrier rectifier in SMA package, featuring 0.60V max forward voltage at 1A and 0.2mA max reverse leakage at 60V/25°C, optimized for high-frequency DC-DC converters and freewheeling applications in power supplies.
For engineers reviewing the B160AX-13 datasheet, B160AX-13 pinout, B160AX-13 application, or B160AX-13 equivalent, key selection criteria include low VF for efficiency, soft switching for EMI control, +150°C junction rating for thermal robustness, and RoHS-compliant lead-free plating for industrial and automotive-qualified designs.
Technical Context
This Schottky diode uses trench MOS structure to reduce forward voltage and leakage simultaneously versus planar Schottky devices. Its soft, fast switching behavior minimizes voltage overshoot and ringing during turn-off in inductive circuits.
Designed for operation up to +150°C junction temperature, it maintains stable VF and IR across temperature with typical VF = 0.45V at 1A/125°C and IR = 22μA at 60V/100°C - critical for thermally constrained SMPS and automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage without breakdown |
| IO (AV) | 1 A - Continuous average forward current on FR-4 PCB with specified pad layout |
| VF (MAX) | 0.60 V @ 1A, 25°C - Low conduction loss enabling >92% efficiency in 5–12V DC-DC stages |
| IR (MAX) | 0.2 mA @ 60V, 25°C - Minimal standby power loss in reverse-biased polarity protection |
| TJ Range | −55°C to +150°C - Enables use in automotive engine control units and industrial motor drives |
| RθJA | 80 °C/W - Thermal resistance defines maximum power dissipation (1.25W) on standard 0.4"×0.5" FR-4 board |
| IFSM | 20 A - Non-repetitive surge capability supports inrush current handling in AC-DC front ends |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, molded plastic with cathode band polarity indicator; dimensions per Diodes Package Outline SMA (A=2.29–2.92mm, B=4.00–4.60mm, C=1.27–1.63mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to lower-potential side (e.g., switch node in buck converter); requires thermal pad connection for power dissipation |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; connects to output rail or ground return; determines polarity protection direction |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF–IR trade-off: 0.60V/0.2mA vs. 0.75V/0.5mA in legacy planar Schottkys |
| Soft, fast switching | Minimizes reverse recovery ringing and EMI in 100kHz–1MHz DC-DC converters |
| +150°C operating junction | Supports derated operation in sealed enclosures or near heat sources without thermal shutdown |
| Lead-free, halogen-free "Green" construction | Complies with RoHS 3 (2015/863/EU) and automotive change-control requirements (AEC-Q101 capable) |
Applications
| DC-DC Converter Output Rectification | Reverse Polarity Protection |
|---|---|
Use Scenario: Used as synchronous rectifier or freewheeling diode in 5V/12V buck converters powering FPGAs and microcontrollers. IC Role / Device Role / Timing Role: Freewheeling path for inductor current during high-side switch off-time; defines minimum on-time and efficiency at light load. Use Value: 0.60V VF reduces conduction loss by ~25% vs. silicon diodes, improving full-load efficiency by 1.8–2.3%. | Use Scenario: Placed in series with VIN to block reverse battery connection in portable medical devices and IoT sensors. IC Role / Device Role / Timing Role: Unidirectional current gate; conducts only when anode > cathode by >0.3V, blocking fault currents up to 60V. Use Value: 0.2mA IR at 60V ensures <1.2μW standby power loss, extending battery life in always-on systems. |
| AC-DC Adapter Secondary Side | Blocking Diode in Solar Charge Controllers |
Use Scenario: Output rectifier in 12V/1A flyback adapters for industrial HMIs and PoE injectors. IC Role / Device Role / Timing Role: Converts transformer secondary AC to regulated DC; handles 20A surge during cold-start capacitor charging. Use Value: 20A IFSM rating prevents failure during repeated inrush events; soft switching avoids transformer core saturation. | Use Scenario: Prevents nighttime battery discharge through PV panel in 12V solar lighting systems. IC Role / Device Role / Timing Role: Reverse-blocking element between panel and battery; must withstand 60V open-circuit panel voltage. Use Value: 60V VRRM and −55°C to +150°C range ensure reliability across desert and arctic deployments. |
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 but planar Schottky; VF = 0.72V max @ 1A, IR = 0.5mA max | Higher conduction loss limits use in high-efficiency or thermally constrained designs | Select only if cost sensitivity outweighs efficiency targets and thermal margin is ≥25°C |
| SS16 (ON Semiconductor) | SMA package, 60V/1A, VF = 0.75V max @ 1A, IR = 0.5mA max, no AEC-Q101 qualification path | Lacks automotive-grade traceability and extended temperature validation | Prefer for commercial-grade consumer power supplies where AEC compliance is not required |
Compared with SB160-E3/54 and SS16, B160AX-13 delivers lower VF and IR due to trench architecture, enabling higher efficiency and better thermal performance - especially valuable in automotive and industrial DC-DC converters where junction temperature exceeds 100°C.

FAQ
What is the maximum junction temperature and how does it affect thermal design?
The B160AX-13 has a rated operating junction temperature range of −55°C to +150°C. At TJ = +150°C, its forward voltage drops to 0.45V and leakage rises to 22μA - both within specification. Thermal design must limit power dissipation using RθJA = 80°C/W on standard FR-4; exceeding this requires larger copper area or forced airflow.
Is B160AX-13 qualified for automotive applications?
B160AX-13 is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While not pre-qualified to AEC-Q101, Diodes offers AEC-Q101-qualified variants (e.g., B160AXQ-13) with full stress test reports; contact Diodes or Aetrix for qualification path support.
How does the trench Schottky structure improve performance over planar Schottky diodes?
The trench architecture reduces series resistance while maintaining low barrier height, achieving 0.60V VF and 0.2mA IR simultaneously - a combination unattainable with planar Schottky processes. This enables higher efficiency at high current density and improved stability across temperature without sacrificing leakage.
What is the recommended PCB layout for optimal thermal performance?
Use the Diodes-recommended SMA pad layout: 0.2" × 0.25" copper pad per terminal on 2oz FR-4, with thermal vias under the cathode pad. Avoid solder mask over thermal pads. Maintain ≥0.5mm clearance to adjacent components to prevent hot-spot coupling and ensure RθJA ≤ 80°C/W.
