Product details
Overview
B130LB-13-F from Diodes Incorporated is a 1.0A surface-mount Schottky barrier rectifier in SMB package, rated for 30V peak repetitive reverse voltage and 40A non-repetitive surge current, with typical forward voltage of 0.395V at 1.0A and thermal resistance of 12°C/W - used in low-voltage DC/DC converter output stages and polarity protection circuits.
For engineers reviewing the B130LB-13-F datasheet, B130LB-13-F pinout, B130LB-13-F application, or B130LB-13-F equivalent, key selection criteria include forward voltage drop at rated current, junction-to-terminal thermal resistance, surge current capability, reverse leakage at elevated temperature, and SMB package compatibility with automated SMT assembly.
Technical Context
This Schottky rectifier employs guard ring die construction to enhance transient immunity and suppress edge breakdown, enabling reliable operation under repetitive surge stress. Its low VF and fast switching response stem from platinum-silicide or similar Schottky barrier metallization on N-type silicon, minimizing minority carrier storage.
The device operates across –55°C to +125°C with no derating required up to 110°C case temperature (2.0A IO), and exhibits 90pF total capacitance at 4V reverse bias - critical for high-frequency flyback snubber and freewheeling paths where capacitive loading affects switching node ringing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum allowable repetitive reverse voltage before avalanche conduction; sets upper limit for input/output rail isolation in 24V systems. |
| IO @ TT=120°C | 1.0 A - Continuous average forward current sustainable at 120°C case temperature; defines steady-state power dissipation limit in thermally constrained layouts. |
| VF @ IF=1.0A | 0.395 V - Forward voltage drop determining conduction loss (0.395W per diode at 1A); directly impacts efficiency in low-voltage buck output stages. |
| IFSM | 40 A - Non-repetitive 8.3ms half-sine surge rating; supports inrush current handling during hot-plug or capacitor charging events. |
| RθJT | 12 °C/W - Junction-to-terminal thermal resistance; enables direct thermal modeling from PCB copper area to junction when mounted on standard 1oz copper pads. |
| IR @ VR=30V, TA=100°C | 20 mA - Reverse leakage at max rated voltage and high temperature; influences standby power loss in always-on polarity protection circuits. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, cathode-banded, RoHS-compliant matte tin terminals, UL 94V-0 molding compound, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or switch node) in freewheeling path; must be routed with low-inductance trace to minimize voltage overshoot. |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band or notch; ties to higher-potential rail (e.g., output capacitor positive) - reverse voltage applied here during off-state. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses localized electric field crowding at die edges, improving surge robustness and long-term reliability under repetitive transient stress. |
| Low VF (0.395V @ 1A) | Reduces conduction loss by >40% versus standard PN rectifiers, enabling higher efficiency in 3.3V–12V DC/DC outputs without heatsinking. |
| SMB package with 12°C/W RθJT | Enables direct thermal coupling to PCB copper pour; achieves 1.0A continuous current with minimal footprint and no external thermal vias in many designs. |
| Lead-free, halogen-free, RoHS-compliant | Meets IPC-J-STD-020 Level 1 moisture sensitivity and JEDEC solderability standards for lead-free reflow (260°C/10s), supporting automated manufacturing. |
Applications
| DC/DC Converter Output Rectification | Polarity Protection Circuit |
|---|---|
Use Scenario: Used as synchronous rectifier replacement or freewheeling diode in 5V/12V buck converters powering FPGAs or microcontrollers. IC Role / Device Role: Schottky rectifier providing low-loss unidirectional current path during low-side switch off-time. Use Value: 0.395V VF minimizes power loss (≤0.4W at 1A), reducing thermal load on compact PCBs without forced air cooling. | Use Scenario: Placed in series with power input to prevent damage from reversed battery or adapter connections. IC Role / Device Role: Unidirectional current gate ensuring only correct-polarity supply energizes downstream circuitry. Use Value: 40A IFSM withstands brief reverse-connection surges; 20mA IR at 100°C ensures <1mW standby loss in always-on systems. |
| High-Frequency Inverter Freewheeling | Low-Voltage Motor Drive Clamp |
Use Scenario: Clamping inductive kickback in 24V BLDC motor gate drivers operating above 100kHz PWM frequency. IC Role / Device Role: Fast-recovery freewheeling path for winding current during MOSFET off-cycle. Use Value: 90pF CT limits displacement current during voltage transitions, suppressing EMI generation in high-dV/dt switching nodes. | Use Scenario: Back-EMF suppression in 5V stepper motor H-bridge driver ICs with integrated power stages. IC Role / Device Role: Bidirectional clamp (anode-to-ground, cathode-to-rail) limiting voltage spikes during current reversal. Use Value: Guard ring structure prevents premature edge breakdown under repetitive 40A surge pulses, extending operational lifetime. |
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 SMB package, 30V VRRM, but VF = 0.45V @ 1A (50mV higher); RθJT = 15°C/W. | Higher conduction loss and thermal resistance reduce usable current in thermally dense layouts. | Select when legacy Vishay qualification or dual-sourcing is mandated; verify thermal margin at full load. |
| SB130 (ON Semiconductor) | Identical 30V/1A rating and SMB package, but VF = 0.47V @ 1A and IR = 500μA @ 25°C (lower leakage). | Lower room-temp leakage benefits ultra-low-power standby, but higher VF increases loss in continuous operation. | Prefer for battery-powered devices requiring sub-μA reverse leakage; avoid in high-duty-cycle power rails. |
Compared with SS13-E3/5AT and SB130, B130LB-13-F delivers the lowest VF (0.395V) and best thermal resistance (12°C/W) among SMB 30V/1A Schottkys, making it optimal for space-constrained, high-efficiency 12V–24V power conversion where thermal headroom is limited.

FAQ
What is the maximum continuous forward current for B130LB-13-F at 100°C ambient?
At 100°C ambient temperature, the device's average rectified current must be derated per Figure 4. With a case temperature limit of 110°C, the usable IO remains 2.0A only if thermal design maintains TT ≤ 110°C - at 100°C ambient, this requires ≤12°C rise, achievable with ≥1 cm² 1oz copper pad. Full 1.0A rating applies at TT = 120°C.
Does B130LB-13-F support lead-free reflow soldering?
Yes - B130LB-13-F features matte tin-plated terminals qualified to MIL-STD-202, Method 208, and supports lead-free reflow profiles up to 260°C for 10 seconds. Its moisture sensitivity level is J-STD-020 Level 1, eliminating bake requirements prior to assembly.
How does the guard ring construction improve reliability?
The guard ring is a doped region surrounding the active Schottky junction that redistributes electric field lines away from the die periphery. This prevents premature avalanche breakdown at sharp edges during voltage transients, increasing IFSM endurance and long-term stability in noisy automotive or industrial power environments.
Can B130LB-13-F replace a 1N5819 in existing designs?
Yes - B130LB-13-F matches 1N5819's 30V/1A rating and shares the same SMB footprint as common SMD replacements. However, its lower VF (0.395V vs. typical 0.45V) reduces conduction loss, and its 40A IFSM exceeds 1N5819's 25A rating, allowing direct substitution with improved thermal and surge performance.
