Product details
Overview
B150B-13-F from Diodes Incorporated is a 50 V, 1.0 A surface-mount Schottky barrier rectifier in SMB package, featuring 0.7 V max forward voltage at 1.0 A and 0.5 mA max reverse leakage at rated VR and +25°C, optimized for low-voltage, high-frequency polarity protection and freewheeling in DC/DC converters and power supplies.
For engineers reviewing the B150B-13-F datasheet, B150B-13-F pinout, B150B-13-F application, or B150B-13-F equivalent, key selection criteria include its 50 V reverse blocking capability, thermal resistance of 20 °C/W (junction-to-terminal), surge rating of 30 A peak, RoHS-compliant matte tin plating, and SMB footprint compatibility with automated SMT assembly.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient immunity and suppress avalanche-induced failure during inductive switching events. Its low VF and fast recovery enable high-efficiency operation in low-voltage (<5 V) power rails where conduction loss dominates system thermal budget.
The device operates across –65 °C to +150 °C and maintains stable IR < 10 mA up to +100 °C, supporting reliable performance in thermally constrained industrial and automotive-adjacent environments without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage before breakdown; defines safe operating limit in polarity protection and flyback clamp circuits. |
| IO (avg) | 1.0 A @ TT = +130°C - Continuous DC output current rating under thermal equilibrium on PCB with 5 mm² copper pad heat sink. |
| VF (max) | 0.7 V @ IF = 1.0 A - Peak forward drop determining conduction loss (0.7 W typical at full load) and junction self-heating. |
| IR (max) | 0.5 mA @ VR = 50 V, TA = +25°C - Reverse leakage limiting standby power loss in battery-backed or always-on systems. |
| IFSM | 30 A @ 8.3 ms half-sine - Non-repetitive surge capacity enabling robustness against inrush or inductive kick events. |
| RθJT | 20 °C/W - Thermal resistance from junction to terminal; used with PCB copper area to calculate ΔTJ under steady-state load. |
| CT | 110 pF @ VR = 4 V, f = 1 MHz - Junction capacitance affecting high-frequency switching noise and EMI filter design in SMPS. |
Pinout & Package
Package: SMB (Surface-Mount Body), molded plastic, UL 94V-0 rated, cathode indicated by band or notch on body, weight ≈ 0.093 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or return path) in polarity protection; must handle full IO and IFSM. |
| Cathode | Forward current exit / reverse blocking node | Connected to input rail in reverse polarity protection; withstands up to 50 V reverse bias with <0.5 mA leakage at +25°C. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge breakdown during voltage transients, improving reliability in noisy power rails and motor drive recirculation paths. |
| Low VF (0.7 V max) | Reduces conduction loss by ~30% vs. comparable silicon diodes, directly lowering thermal stress in compact 1A DC/DC modules. |
| 30 A surge rating | Withstands single-event inductive energy spikes (e.g., relay coil de-energization) without degradation or short-circuit failure. |
| Lead-free, RoHS-compliant plating | Matte tin finish ensures solderability per MIL-STD-202 Method 208 and eliminates lead-based contamination in consumer and industrial assemblies. |
Applications
| Polarity Protection | Freewheeling Diode |
|---|---|
Use Scenario: Input protection for USB-powered peripherals or 5 V/12 V embedded controllers against accidental reverse battery connection. IC Role / Device Role / Timing Role: Unidirectional current gate placed between power source and system input capacitor. Use Value: Prevents damage to downstream ICs with only 0.7 V drop at 1 A, preserving >94% of supply voltage under full load. | Use Scenario: Energy recirculation path for inductive loads such as solenoids, relays, or small DC motors in PLC I/O modules. IC Role / Device Role / Timing Role: Clamping diode across inductor terminals to absorb back-EMF during switch-off transitions. Use Value: Limits voltage spike to ≤50 V with fast recovery, eliminating need for snubbers and reducing PCB space by 40% vs. slower alternatives. |
| Low-Voltage DC/DC Output | High-Frequency Inverter Clamp |
Use Scenario: Secondary-side rectification in isolated 3.3 V/5 V flyback converters for IoT sensor nodes and wearables. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in cost-sensitive designs where MOSFET control complexity is avoided. Use Value: Enables >88% efficiency at 1 A due to low VF and minimal stored charge, extending battery life without requiring gate-drive circuitry. | Use Scenario: Voltage clamping in half-bridge inverters driving piezoelectric actuators or ultrasonic transducers. IC Role / Device Role / Timing Role: Bidirectional clamp limiting transient overvoltage on bridge legs during fast switching edges. Use Value: Withstands 30 A surge peaks and dissipates clamp energy with <20 °C/W thermal resistance, avoiding thermal runaway at 100 kHz+ switching. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS15-E3/5AT (Vishay) | Same SMB package, 50 V VRRM, but VF = 0.52 V typ @ 1 A (lower conduction loss); IR = 0.2 mA max @ 25°C (tighter leakage spec). | Better suited for ultra-low-power battery systems where sub-100 µA standby leakage matters. | Select when minimizing no-load power loss is critical; verify layout compatibility with Vishay's pad recommendations. |
| SB150 (ON Semiconductor) | SMB package, 50 V VRRM, VF = 0.75 V max @ 1 A (slightly higher drop); RθJT = 25 °C/W (reduced thermal performance). | Marginally higher thermal rise under continuous 1 A load; may require larger copper area for same TJ. | Acceptable where cost sensitivity outweighs thermal margin; confirm IR spec meets system leakage budget at elevated temperature. |
Compared with SS15-E3/5AT and SB150, B150B-13-F delivers balanced trade-offs: lower VF than SB150 for reduced conduction loss, tighter thermal resistance than SB150 for better power density, and broader availability than SS15-E3/5AT in standard distribution channels.

FAQ
What is the maximum junction temperature for continuous operation of B150B-13-F?
The device supports continuous operation up to +150 °C junction temperature, with derated average current beginning at +130 °C terminal temperature per the forward current derating curve. At +150 °C, IO drops to approximately 0.6 A, ensuring safe thermal margin under worst-case ambient and PCB trace resistance conditions.
Can B150B-13-F be used in automotive applications?
B150B-13-F is not AEC-Q101 qualified and lacks PPAP documentation or IATF 16949-certified manufacturing traceability. It may be used in non-safety-critical automotive-adjacent systems (e.g., infotainment power rails) only after full system-level validation, but Diodes recommends dedicated AEC-Q101 parts like the B150BQ-13-F for qualified automotive use.
How does the SMB package of B150B-13-F compare to SMA in thermal performance?
The SMB package has identical RθJT = 20 °C/W as the SMA variant when mounted on equivalent 5 mm² copper pads, but its larger body (2.00–2.50 mm A-dimension vs. SMA's 2.29–2.92 mm) provides greater surface area for convection cooling and improved mechanical stability during reflow, especially in high-vibration environments.
Is B150B-13-F compatible with lead-free reflow profiles?
Yes - B150B-13-F features matte tin plating qualified to MIL-STD-202 Method 208 and supports JEDEC J-STD-020 moisture sensitivity Level 1. It withstands peak reflow temperatures up to 260 °C for 30 seconds without delamination or solder joint integrity loss, meeting IPC/JEDEC Class 3 assembly requirements.
