Product details
Overview
B160BQ-13-F from Diodes Incorporated is a 60 V, 1.0 A surface-mount Schottky barrier rectifier in SMB package, with 0.7 V max forward voltage at 1.0 A and 0.5 mA max reverse leakage at 25°C, designed for polarity protection, freewheeling, and low-voltage DC/DC converter output rectification in automotive and industrial power supplies.
For engineers reviewing the B160BQ-13-F datasheet, B160BQ-13-F pinout, B160BQ-13-F application, or B160BQ-13-F equivalent, key selection criteria include its AEC-Q101 qualification, 30 A non-repetitive surge rating, 65 °C/W thermal resistance with heatsink, RoHS-compliant matte tin plating, and SMB package compatibility with automated SMT assembly.
Technical Context
This Schottky diode uses guard ring die construction to enhance transient robustness and suppress edge breakdown, enabling reliable operation under repetitive voltage surges and fast switching transitions. Its low VF and low CT (110 pF) support high-frequency rectification up to several MHz in synchronous buck converters and flyback snubbers.
The device operates across –65°C to +150°C junction temperature range and is rated for 60 V peak repetitive reverse voltage (VRRM), with leakage current tightly controlled at ≤0.5 mA @ 60 V, 25°C - critical for battery-powered systems requiring ultra-low standby loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum reverse blocking capability without breakdown; suitable for 48 V nominal bus systems with safety margin. |
| IO(AVG) | 1.0 A - Continuous average forward current at TJ = +130°C; supports compact PCB layouts without forced air cooling. |
| VF(max) | 0.7 V @ IF = 1.0 A - Low conduction loss enables >92% efficiency in 5–12 V output DC/DC stages. |
| IR(max) | 0.5 mA @ VR = 60 V, TA = 25°C - Enables use in low-power hold-up and backup circuits where leakage must be minimized. |
| tRR | 12 ns - Fast recovery reduces switching losses and EMI in high-frequency (>100 kHz) topologies. |
| RθJA | 65 °C/W (with 50×50×23 mm Al heatsink) - Enables thermal design margin for sustained 1 A load at ambient ≤85°C. |
| IFSM | 30 A (8.3 ms half-sine) - Withstands inrush currents from large bulk capacitors during hot-plug events. |
Pinout & Package
Package: SMB (Surface-Mount Small Outline Diode), molded plastic case per UL 94V-0, cathode indicated by band on body. Terminals are matte tin-plated for solderability per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node in buck converter); accepts 1.0 A continuous forward current. |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; connects to higher-potential rail (e.g., output capacitor positive); blocks up to 60 V reverse bias. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge avalanche, improving reliability under repetitive transient stress (e.g., load dump in automotive). |
| AEC-Q101 qualification | Validated for automotive-grade temperature cycling, HTRB, and ESD (HBM 4 kV), supporting Tier-1 supply chain requirements. |
| Lead-free & halogen-free | Meets RoHS 3 (2015/863/EU) and Diodes Inc.'s "Green" definition (<900 ppm Br/Cl, <1000 ppm Sb). |
| PPAP capability | Supports production part approval process documentation for OEM automotive programs. |
Applications
| Automotive Body Control Module (BCM) | Industrial 24 V DC Power Supply |
|---|---|
Use Scenario: Reverse polarity protection on 12 V/24 V input rails of BCM modules exposed to field wiring errors. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed in series with main input to prevent damage from accidental battery reversal. Use Value: 0.7 V VF minimizes voltage drop and heat generation at 1 A load; AEC-Q101 rating ensures operation over full automotive temperature range. | Use Scenario: Freewheel diode in 24 V offline flyback converter secondary-side rectification. IC Role / Device Role / Timing Role: Provides low-loss path for inductor current during MOSFET off-time, reducing switching losses and output ripple. Use Value: 12 ns tRR and 110 pF CT limit ringing and EMI; 30 A IFSM handles startup surges into cold capacitors. |

IC Role / Device Role / Timing Role: Prevents backfeed between sources while enabling seamless source switchover. Use Value: 0.5 mA IR at 25°C ensures minimal quiescent drain from Li-ion battery during standby; SMB footprint saves board space. | Use Scenario: Polarity protection for PoE-powered smart home hub (IEEE 802.3af/at). IC Role / Device Role / Timing Role: Series-connected input protection diode on 48 V PoE input before DC/DC conversion. Use Value: 60 V VRRM exceeds PoE's 57 V max open-circuit voltage; RoHS/Green compliance meets EU eco-design directives. |
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 SMB package, 60 V VRRM, 1.0 A IO, but VF = 0.75 V (max @ 1 A); no AEC-Q101 qualification. | Not approved for automotive use; suitable only for commercial/industrial environments. | Select when AEC-Q101 is not required and cost sensitivity outweighs thermal margin. |
| SS16 (ON Semiconductor) | SMB package, 60 V VRRM, 1.0 A IO, VF = 0.72 V (max @ 1 A); AEC-Q101 qualified but IR = 1.0 mA @ 60 V, 25°C. | Higher leakage limits use in battery-holdup or ultra-low-power standby circuits. | Select when footprint compatibility is critical and leakage tolerance ≥1 mA is acceptable. |
Compared with SB160-E3/54 and SS16, B160BQ-13-F delivers tighter IR control (0.5 mA vs. ≥1.0 mA) and verified PPAP readiness - making it preferred for automotive BCMs and safety-critical industrial power inputs where leakage-induced system wake-up or thermal drift must be avoided.

FAQ
Is B160BQ-13-F suitable for use in automotive infotainment systems?
Yes. It is AEC-Q101 qualified and PPAP capable, with operating temperature range of –65°C to +150°C and tested for thermal cycling, HTRB, and ESD. Its 60 V VRRM and low VF make it appropriate for 12 V/24 V infotainment power rails, including display backlight drivers and USB charging ports.
What is the maximum allowable ambient temperature for continuous 1.0 A operation?
At 1.0 A DC load with a 50 mm × 50 mm × 23 mm aluminum heatsink, the maximum ambient temperature is +85°C (per Figure 10 derating curve). Without heatsink, RθJA = 115 °C/W limits continuous 1.0 A operation to ambient ≤55°C to maintain TJ ≤130°C.
Does B160BQ-13-F have a specified junction-to-case thermal resistance (RθJC)?
No - the datasheet specifies only RθJA (115 °C/W on FR-4, 65 °C/W with heatsink). RθJC is not published; thermal modeling should rely on transient thermal impedance curves (Figure 11) or vendor-provided simulation models for precise junction temperature estimation.
Can B160BQ-13-F replace B160Q-13-F in existing designs?
Yes, with mechanical and electrical equivalence: both share SMB package, identical pinout, and same electrical specs (VRRM = 60 V, VF = 0.7 V max, IR = 0.5 mA max). The "B" suffix denotes enhanced automotive qualification (AEC-Q101 + PPAP), making B160BQ-13-F a direct upgrade for new or revised automotive designs.
