Product details
Overview
B130Q-13-F from Diodes Incorporated is a 1.0A surface-mount Schottky barrier rectifier with 30V peak repetitive reverse voltage (VRRM), 0.5V max forward voltage at 1.0A, and 0.5mA max reverse leakage current at 25°C - designed for polarity protection and freewheeling in low-voltage DC/DC converters and automotive power rails.
For engineers reviewing the B130Q-13-F datasheet, B130Q-13-F pinout, B130Q-13-F application, or B130Q-13-F equivalent, key selection criteria include its AEC-Q101 qualification, SMA package thermal resistance (115°C/W on FR-4), 30A non-repetitive surge rating, and suitability for high-frequency switching below 100kHz where low conduction loss is critical.
Technical Context
This Schottky diode employs guard ring die construction to suppress transient-induced avalanche failure and supports automated SMT assembly with lead-free matte tin plating compliant to RoHS 3 and halogen/antimony-free "Green" standards. Its low VF enables efficient operation in 3.3V–24V input power stages.
Rated for continuous 1.0A average output current at TT = +130°C, it delivers 12ns typical reverse recovery time (tRR) and 110pF junction capacitance at 4V reverse bias - enabling use in flyback snubbers and synchronous rectifier auxiliary paths without excessive switching loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - blocks up to 30V reverse transients in 24V automotive systems without breakdown |
| IO | 1.0 A - sustains continuous 1A DC output in compact power supplies with derated ambient limits |
| VF Max | 0.5 V @ 1.0A - reduces conduction loss to ≤0.5W per diode in 12V/1A buck outputs |
| IR Max | 0.5 mA @ 30V, 25°C - ensures minimal standby leakage in battery-backed circuits |
| tRR | 12 ns - enables clean commutation in <100kHz PWM topologies without tail current |
| RθJA | 115 °C/W - requires minimal PCB copper area (1×1 inch 2oz FR-4) for thermal management |
| IFSM | 30 A - withstands inrush surges from hot-plug connectors or capacitor charging events |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with UL 94V-0 flammability rating, cathode indicated by band on body. Weight: 0.064 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node or ground return) in freewheel path |
| Cathode | Forward current exit / reverse blocking terminal | Connected to higher-potential rail (e.g., input supply or inductor output) for polarity protection |
Key Features
| Feature | Design Value |
|---|---|

Use Scenario: Suppressing inductive kickback in 24V brushed DC motor H-bridge drivers. IC Role / Device Role / Timing Role: Recirculating diode across motor winding during PWM off-cycle. Use Value: Handles 30A surge peaks without thermal runaway due to robust die metallization. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS13-E3/5AT (Vishay) | Same SMA package, 30V VRRM, but VF = 0.55V @ 1A and IR = 0.2mA @ 25°C | Lower leakage suits ultra-low-power sleep modes; slightly higher VF increases conduction loss | Select when minimizing standby current outweighs conduction loss in battery-critical designs |
| SB130 (ON Semiconductor) | SMB package (larger footprint), same 30V/1A rating, VF = 0.52V @ 1A, RθJA = 65°C/W with heatsink | Higher thermal mass supports sustained 1A loads above 85°C ambient | Choose for industrial environments requiring extended temperature margin without PCB copper expansion |
Compared with SS13-E3/5AT and SB130, B130Q-13-F offers optimal balance of AEC-Q101 compliance, ultra-low VF, and standardized SMA footprint - making it preferred for space-constrained automotive modules where both reliability and efficiency are prioritized.

FAQ
Is B130Q-13-F suitable for reflow soldering?
Yes. B130Q-13-F features lead-free matte tin plating and meets JEDEC J-STD-020 Level 1 moisture sensitivity requirements, supporting standard Pb-free reflow profiles up to 260°C peak temperature without delamination or solder joint defects.
What is the maximum operating temperature for continuous 1.0A current?
The device supports 1.0A average forward current up to +130°C case temperature (TT). At 25°C ambient on a standard 1×1 inch 2oz FR-4 board, derating begins above +70°C ambient per Figure 10 in DS38236 Rev. 4-2.
Does B130Q-13-F have a specified junction-to-case thermal resistance?
No. The datasheet specifies only junction-to-ambient thermal resistance: 115°C/W on FR-4 (Note 6) and 65°C/W with 50mm×50mm×23mm aluminum heatsink (Note 7). Junction-to-case value is not published in DS38236.
Can B130Q-13-F replace B130 in legacy designs?
Yes, with verification of mechanical fit. B130Q-13-F uses the same SMA package as B130 but adds AEC-Q101 qualification, RoHS 3 compliance, and tighter VF/IR specifications - no electrical redesign is needed for most 30V/1A applications.
