Product details
Overview
B1100B-13 from Diodes Incorporated is a 100 V, 1.0 A high-voltage Schottky barrier rectifier in SMB package, featuring low forward voltage (0.79 V @ 1.0 A, 25°C), 30 A non-repetitive surge capability, and guard-ring die construction for transient protection-used in DC/DC converter output rectification and polarity protection circuits.
For engineers reviewing the B1100B-13 datasheet, B1100B-13 pinout, B1100B-13 application, or B1100B-13 equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (25 K/W), junction capacitance (80 pF), surge robustness (30 A, 8.3 ms), and SMB package compatibility with automated SMT assembly.
Technical Context
This Schottky rectifier employs a guard-ring die structure to enhance transient immunity and suppress leakage under high dv/dt conditions. Its low VF and fast recovery (<10 ns) stem from majority-carrier conduction, eliminating minority-carrier storage delay.
Rated for 125°C terminal temperature operation, it delivers 1.0 A average forward current with derating above 125°C per Fig. 1. Junction-to-terminal thermal resistance is 25 K/W under specified mounting conditions (terminals held at ambient).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in 48 V or 60 V bus polarity protection. |
| IO @ TT=125°C | 1.0 A - Continuous average forward current with heatsink-free mounting on PCB copper; requires ≥1 cm² 2-oz copper pad for full rating. |
| VFM @ IF=1.0A, 25°C | 0.79 V - Low conduction loss enables >92% efficiency in 5–12 V output rectification at 1 A. |
| IFSM (8.3 ms) | 30 A - Withstands single-line surges (e.g., hot-swap, load dump) without failure; validated per JEDEC Method. |
| RJT | 25 K/W - Enables direct thermal path from junction to solder joint; critical for thermal design in enclosed power modules. |
| Cj @ 4 V, 1 MHz | 80 pF - Limits high-frequency switching noise and EMI in 100–500 kHz DC/DC converters. |
Pinout & Package
SMB (DO-214AA) surface-mount plastic package with cathode band marking; terminals are solder-plated and compliant with MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current entry point | Connected to unregulated input rail; must withstand full surge current and reverse recovery stress. |
| Cathode | Output current exit point | Drives output capacitor and load; low VF minimizes voltage drop and heat generation at 1 A. |
Key Features
| Feature | Design Value |
|---|---|
| Guard-ring die construction | Improves surge immunity and reduces IR drift under transient overvoltage, extending reliability in industrial power supplies. |
| Low VF (0.79 V @ 1 A) | Reduces conduction loss by ~35% vs. comparable 1 A silicon rectifiers, lowering thermal load in space-constrained designs. |
| 30 A IFSM rating | Supports robust operation during cold-start, hot-plug, or short-circuit recovery without bond-wire fusing. |
| UL 94V-0 plastic case | Meets flammability requirements for Class II insulated AC/DC adapters and medical power supplies. |
Applications
| DC/DC Converter Output Rectification | Polarity Protection Circuit |
|---|---|
Use Scenario: Secondary-side rectification in isolated 5–24 V flyback or forward converters delivering up to 1 A. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer AC output to regulated DC; no timing function. Use Value: 0.79 V VF reduces power loss to 0.79 W at 1 A, enabling compact thermal design without heatsink. | Use Scenario: Reverse-voltage blocking in USB-C PD power paths or battery backup inputs. IC Role / Device Role / Timing Role: Passive polarity enforcement device; conducts only when anode > cathode by >0.3 V. Use Value: 100 V VRRM supports 48 V systems with 20% margin; SMB footprint fits tight board layouts. |
| Free-Wheeling Diode | Low-Voltage Inverter Output Stage |
Use Scenario: Inductive energy recirculation across MOSFET switches in 12 V automotive motor drivers. IC Role / Device Role / Timing Role: Provides low-loss current path during switch-off phase; zero reverse recovery time prevents shoot-through. Use Value: Fast majority-carrier conduction eliminates reverse recovery charge (Qrr ≈ 0), reducing EMI and switching loss. | Use Scenario: Output stage of 24 V solar microinverters operating at 100–200 kHz switching frequency. IC Role / Device Role / Timing Role: High-frequency rectifier handling bidirectional PWM-modulated current waveforms. Use Value: 80 pF junction capacitance limits displacement current and capacitive coupling noise at 200 kHz. |
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 from Micro Commercial Components | Same SMB package, 100 V VRRM, but VF = 0.85 V @ 1 A and RJT = 30 K/W. | Higher conduction loss and thermal resistance reduce usable current in thermally constrained layouts. | Select if cost sensitivity outweighs 60 mW extra loss and 5 K/W higher thermal impedance. |
| SB1100-E3/52 from Vishay | SMB package, 100 V VRRM, VF = 0.82 V @ 1 A, IRM = 1.0 mA @ 25°C (vs. 0.5 mA for B1100B-13). | Higher leakage may affect standby power in always-on IoT devices; otherwise functionally interchangeable. | Prefer for legacy Vishay-design platforms; verify leakage impact in <10 µA standby systems. |
Compared with SS110-TP and SB1100-E3/52, B1100B-13 offers the lowest VF (0.79 V) and tightest IRM (0.5 mA), making it optimal for high-efficiency, low-leakage 1 A rectification where thermal headroom and standby current matter.

FAQ
What is the maximum junction temperature for continuous operation?
The B1100B-13 has an operating junction temperature range of –65°C to +150°C. For continuous 1.0 A operation, the terminal temperature must be maintained at ≤125°C per the derating curve (Fig. 1); exceeding this requires proportional current reduction to avoid thermal runaway.
Is the B1100B-13 suitable for use in automotive applications?
Yes-its –65°C to +150°C operating range, UL 94V-0 flammability rating, and 30 A surge rating meet baseline requirements for under-hood auxiliary power modules and infotainment DC/DC supplies, though AEC-Q101 qualification is not claimed.
How does the guard-ring die construction improve reliability?
The guard-ring structure surrounds the active Schottky junction to suppress edge breakdown and reduce leakage current under high electric field stress, improving long-term stability during repetitive transient events like load dumps or ESD spikes.
Can B1100B-13 replace a standard silicon rectifier in a 12 V power supply?
Yes-its 100 V VRRM and 1.0 A IO rating exceed typical 12 V supply requirements. Replacing a 1N4007 yields lower VF (0.79 V vs. ~1.1 V), reduced heat, and faster switching, but note its higher IRM (0.5 mA vs. 5 µA), which may affect ultra-low-power standby.
