Product details
Overview
B1100B-13-F from Diodes Incorporated is a 100 V, 1.0 A high-voltage Schottky barrier rectifier in SMB package, featuring 0.79 V max forward voltage at 1.0 A and 0.5 mA max reverse leakage at rated VR and +25°C. It serves as a polarity protection, freewheeling, or blocking diode in DC-DC converters and low-voltage-drop power supplies.
For engineers reviewing the B1100B-13-F datasheet, B1100B-13-F pinout, B1100B-13-F application, or B1100B-13-F equivalent, key selection criteria include its 100 V reverse voltage rating, low VF for reduced conduction loss, SMB thermal resistance (RθJT = 25 °C/W), and JEDEC-qualified reliability for industrial and automotive-adjacent designs.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient robustness and suppress avalanche-induced failure under repetitive surge conditions. Its low forward voltage (0.79 V @ 1.0 A, +25°C) and low junction-to-terminal thermal resistance (25 °C/W) enable efficient operation in thermally constrained layouts.
It exhibits 80 pF total capacitance at 4 V reverse bias and 1.0 A non-repetitive peak forward surge current capability (8.3 ms half-sine), supporting reliable operation in switching power supply freewheeling paths and reverse-polarity protection circuits with moderate dV/dt stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse voltage before breakdown; sets upper limit for blocking capability in DC-DC input stages |
| IO (AV) | 1.0 A @ TT = +125°C - average forward current rating under terminal-heated conditions; defines continuous power handling |
| VF Max | 0.79 V @ IF = 1.0 A, TA = +25°C - limits conduction loss to ≤790 mW at full load; critical for efficiency in low-voltage rails |
| IR Max | 0.5 mA @ VR = 100 V, TA = +25°C - ensures minimal standby leakage in battery-backed or always-on systems |
| RθJT | 25 °C/W - junction-to-terminal thermal resistance; enables direct PCB copper pad heatsinking without external heatsink |
| IFSM | 30 A (8.3 ms half-sine) - surge rating supports inrush and fault-current tolerance in converter output stages |
| CT | 80 pF @ VR = 4 V, f = 1 MHz - low capacitance minimizes switching loss and EMI in high-frequency (>100 kHz) topologies |
Pinout & Package
Package: SMB (Surface-Mount Body), molded plastic, RoHS-compliant matte tin terminals, cathode band polarity marking. Dimensions: 3.30–3.94 mm (L) × 4.06–4.57 mm (W) × 1.96–2.21 mm (H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node or ground return); must handle full 1.0 A continuous and 30 A surge |
| Cathode | Forward current exit / reverse-blocking terminal | Marked with band; connects to higher-potential rail (e.g., input bus or VOUT); sustains up to 100 V reverse bias |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves ESD and transient immunity without requiring external TVS; validated per JEDEC standards |
| Low VF (0.79 V max) | Reduces power dissipation by ≥30% vs. comparable PN rectifiers at 1 A, lowering thermal stress on PCB |
| SMB package with 25 °C/W RθJT | Enables >0.8 W power dissipation with <20°C rise over ambient using standard 25 mm² copper pad |
| Lead-free, halogen-free "Green" construction | Complies with RoHS 3 (2015/863/EU) and automotive-qualifiable standards; suitable for reflow up to +260°C/10 s |
Applications
| DC-DC Converter Freewheeling Diode | Polarity Protection in 12 V Automotive Modules |
|---|---|
Use Scenario: Used across the low-side switch in synchronous buck converters operating at 200–500 kHz. IC Role / Device Role / Timing Role: Freewheeling path during high-side switch off-time; conducts 1.0 A continuously with minimal voltage drop. Use Value: 0.79 V VF reduces conduction loss to 790 mW, limiting temperature rise and enabling smaller thermal pads. | Use Scenario: Placed in series with 12 V supply input to prevent damage from reverse battery connection. IC Role / Device Role / Timing Role: Blocking diode; blocks reverse current while passing forward current with <0.8 V drop. Use Value: 100 V VRRM provides 8× margin over 12 V nominal, ensuring robustness against load dump transients. |
| AC-DC Output Rectification (5–24 V) | Blocking Diode in Solar Charge Controllers |
Use Scenario: Secondary-side rectifier in isolated flyback or forward converters delivering 5–24 V at ≤1 A. IC Role / Device Role / Timing Role: Unidirectional current path converting transformer AC output to regulated DC. Use Value: 80 pF CT minimizes switching noise coupling into feedback networks, improving regulation stability. | Use Scenario: Prevents reverse current flow from battery to PV panel at night or low-light conditions. IC Role / Device Role / Timing Role: Reverse-blocking element in series with battery terminal. Use Value: 0.5 mA IR max at +25°C ensures negligible nighttime battery drain (<1.2 mAh/day per diode). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS110-TP (Micro Commercial) | Same SMB package, 100 V VRRM, but VF = 0.85 V max @ 1 A; RθJT = 30 °C/W | Higher conduction loss and thermal resistance reduce usable current in compact layouts | Select when cost sensitivity outweighs thermal or efficiency requirements |
| SB1100 (ON Semiconductor) | SMB package, 100 V VRRM, VF = 0.82 V max @ 1 A; IR = 0.5 mA same; not AEC-Q qualified | Lacks JEDEC automotive qualification; unsuitable for mission-critical automotive modules | Prefer for industrial non-automotive use where qualification is not mandated |
Compared with SS110-TP and SB1100, B1100B-13-F delivers lower VF (0.79 V), superior thermal resistance (25 vs. 30 °C/W), and JEDEC-qualified reliability-making it optimal for space-constrained, efficiency-sensitive, and automotive-adjacent power designs.

FAQ
What is the maximum junction temperature for B1100B-13-F?
The device has an operating junction temperature range of –65°C to +150°C. Its thermal resistance (RθJT = 25 °C/W) allows safe operation at full 1.0 A load with ≤20°C junction-to-terminal rise when mounted on a 25 mm² copper pad, assuming terminal temperature remains ≤+125°C.
Is B1100B-13-F suitable for automotive applications?
B1100B-13-F is JEDEC-qualified for high reliability and shares design lineage with the AEC-Q-qualified B1100BQ variant. While not itself AEC-Q certified, its guard ring die, 150°C TJ rating, and green RoHS compliance make it appropriate for non-safety-critical automotive subsystems like infotainment power rails or body control modules.
How does the SMB package compare to SMA for this part?
B1100B-13-F uses the larger SMB package (vs. SMA in B1100-13-F), offering 20% greater thermal mass and 25 °C/W RθJT versus ~35 °C/W for SMA. This enables higher sustained current in thermally limited layouts and improved mechanical robustness during reflow and board flex.
Can B1100B-13-F replace a standard PN rectifier in existing designs?
Yes-provided reverse voltage and surge requirements are met. Its 100 V VRRM and 30 A IFSM match or exceed many 1 A PN rectifiers, while its 0.79 V VF cuts conduction loss nearly in half. Layout changes are unnecessary since SMB footprint is industry-standard and compatible with common SMT stencil apertures.
