Product details
Overview
B150BQ-13-F from Diodes Incorporated is a 1.0A, 50V surface-mount Schottky barrier rectifier in SMB package, featuring 0.7V max forward voltage at 1.0A, 0.5mA max reverse leakage at 25°C, 30A non-repetitive surge rating, and AEC-Q101 qualification for automotive use. It serves as a low-loss freewheel or polarity protection diode in DC/DC converters and power supply rails.
For engineers reviewing the B150BQ-13-F datasheet, B150BQ-13-F pinout, B150BQ-13-F application, or B150BQ-13-F equivalent, key selection criteria include its 50V reverse blocking capability, thermal resistance (65°C/W with heatsink), RoHS-compliant matte tin plating, and suitability for high-frequency switching in space-constrained automotive modules.
Technical Context
This Schottky rectifier uses guard ring die construction to suppress transient-induced junction breakdown and supports automated SMT assembly with standard reflow profiles. Its low VF and fast recovery (12ns tRR) minimize conduction and switching losses in buck converter freewheel paths and reverse-polarity protection circuits.
Rated for operation from –65°C to +150°C, it delivers stable performance across automotive under-hood environments. The SMB package provides higher thermal mass than SMA, enabling 1.0A continuous current at 130°C case temperature when mounted on a 50mm×50mm×23mm aluminum heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage before avalanche; defines safe DC blocking margin in 24V automotive systems. |
| IO (avg) | 1.0 A - Continuous average forward current at TT = +130°C; supports sustained load in compact power rails. |
| VF (max) | 0.7 V @ 1.0A - Low forward drop reduces power loss (0.7W typical) and thermal stress in high-duty-cycle applications. |
| IR (max) | 0.5 mA @ 50V, 25°C - Low leakage preserves battery standby time in always-on vehicle modules. |
| tRR | 12 ns - Fast reverse recovery enables efficient operation up to ~1 MHz switching frequencies in SMPS. |
| RθJA (with heatsink) | 65 °C/W - Enables 1.0A operation without derating when used with specified Al heatsink per Note 7. |
| IFSM | 30 A - Withstands short-circuit surges in automotive load-dump or hot-swap events. |
Pinout & Package
Package: SMB (Surface-Mount Body), molded plastic case with UL 94V-0 flammability rating, cathode indicated by band or notch, lead-free matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/source side of rectification path; must withstand peak surge currents up to 30A. |
| Cathode | Forward current exit / reverse-blocking terminal | Connected to output/load side; polarity marking ensures correct orientation for reverse-voltage protection. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge breakdown during voltage transients, improving reliability in noisy automotive electrical systems. |
| AEC-Q101 qualification | Validated for automotive-grade temperature cycling, humidity, and mechanical shock per JEDEC standards. |
| RoHS & Halogen-free compliance | Meets EU Directive 2015/863/EU with <900ppm Br, <900ppm Cl, <1000ppm Sb; supports green manufacturing requirements. |
| Surge rating: 30A IFSM | Withstands single half-sine surge (8.3ms) without degradation-critical for load-dump protection in 12V/24V systems. |
Applications
| Automotive Body Control Module (BCM) | Industrial DC/DC Converter Output Stage |
|---|---|
Use Scenario: Reverse-polarity protection on 12V input rail of BCM microcontroller power supply. IC Role / Device Role / Timing Role: Polarity protection diode placed in series with input to block reverse connection damage. Use Value: 0.7V VF minimizes voltage drop and heat generation at 1A peak load, preserving system efficiency and thermal margin. |
Use Scenario: Freewheel diode in synchronous buck converter output stage operating at 500kHz. IC Role / Device Role / Timing Role: Recirculating diode providing low-loss current path during high-side FET off-time. Use Value: 12ns tRR and low CT (110pF) reduce switching losses and EMI, supporting stable regulation at high frequency. |
| Smart Rearview Mirror Power Input | USB-C PD Power Path Protection |
Use Scenario: Blocking diode isolating auxiliary 5V rail from main camera sensor supply to prevent backfeed. IC Role / Device Role / Timing Role: Blocking diode ensuring unidirectional power flow between isolated subsystems. Use Value: 0.5mA IR at 25°C limits standby current drain, extending battery life in always-on mirror systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB150-E3/54 (Vishay) | Same 50V VRRM, 1.0A IO, but VF = 0.85V (max @ 1A); SMB package; no AEC-Q101 qualification. | Not qualified for automotive; suitable only for industrial/commercial designs without automotive reliability requirements. | Select if AEC-Q101 is not required and cost sensitivity outweighs 0.15V VF penalty. |
| SS15 (ON Semiconductor) | 50V VRRM, 1.0A IO, VF = 0.55V (typ), but IR = 1.0mA (max @ 25°C); SMA package; AEC-Q101 qualified. | SMA footprint requires PCB redesign; lower VF improves efficiency but higher IR may impact ultra-low-power standby. | Select when board space allows SMA and lower conduction loss is prioritized over leakage-critical standby operation. |
Compared with SB150-E3/54 and SS15, B150BQ-13-F uniquely balances AEC-Q101 compliance, 0.7V VF, and 0.5mA IR in SMB form-making it optimal for automotive modules where thermal, reliability, and footprint constraints coexist.

FAQ
What is the maximum junction temperature for continuous operation?
The B150BQ-13-F is rated for continuous operation up to TJ = +150°C. At TA = +25°C with no heatsink, derating begins above ~75°C ambient per Figure 10; with the specified 50mm×50mm×23mm Al heatsink, full 1.0A current is supported up to TA = +130°C.
Is this device suitable for use in a synchronous rectifier circuit?
No-B150BQ-13-F is a passive Schottky rectifier, not a synchronous MOSFET controller or driver. It functions as a freewheeling or blocking diode in non-synchronous topologies; for synchronous rectification, an active gate-driven MOSFET and associated controller are required.
Does the "-13-F" suffix indicate tape-and-reel packaging?
Yes-the "-13-F" suffix denotes 3,000-piece tape-and-reel packaging in SMB case format, with lead-free (RoHS-compliant) matte tin plating and AEC-Q101 qualification. "-13" specifies the reel size and packaging standard; "F" confirms halogen- and antimony-free "Green" compliance.
Can this diode replace a B150Q-13-F in an existing design?
Yes-B150BQ-13-F is the SMB-package variant of the B150Q-13-F (SMA), sharing identical electrical specifications (50V VRRM, 1.0A IO, 0.7V VF), AEC-Q101 qualification, and RoHS/Green status. Only PCB footprint and thermal performance differ due to SMB's larger thermal mass.
