Product details
Overview
S1BB-13 from Diodes Incorporated is a surface-mount, glass-passivated silicon rectifier diode in SMB package, rated for 100 V peak repetitive reverse voltage (VRRM), 1.0 A average forward current (IO), and 30 A non-repetitive surge current (IFSM). It serves as a general-purpose AC-to-DC conversion element in power supplies, adapters, and DC input protection circuits.
For engineers reviewing the S1BB-13 datasheet, S1BB-13 pinout, S1BB-13 application, or S1BB-13 equivalent, key selection criteria include its 1.1 V max forward voltage at 1.0 A, 100 µA max reverse leakage at +125°C, 3.0 µs max reverse recovery time, SMB thermal resistance of 30 °C/W, and RoHS-compliant matte tin plating.
Technical Context
This device operates as a unidirectional, single-phase, half-wave rectifier with glass-passivated junction for enhanced moisture and contamination resistance. Its 100 V VRRM rating targets low-voltage AC line inputs (e.g., 70 V RMS) and DC bus clamping in 12–48 V systems.
Thermal performance is defined by junction-to-terminal resistance of 30 °C/W when mounted on 5.0 mm² copper pads, enabling reliable operation up to +150°C junction temperature. Reverse recovery time (trr ≤ 3.0 µs) supports moderate-frequency switching in flyback snubbers and input stage rectification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Withstands peak reverse transients up to 100 V without breakdown in AC line or inductive load applications. |
| IO @ TT = +100°C | 1.0 A - Continuous DC output current capability under standard thermal pad conditions at terminal temperature of 100°C. |
| IFSM (8.3 ms) | 30 A - Survives short-duration surges typical of cold-start inrush or lightning-induced line spikes. |
| VFM @ IF = 1.0 A | ≤1.1 V - Limits conduction loss to ≤1.1 W per diode at full rated current, critical for thermal budget in compact layouts. |
| IRM @ +125°C | ≤100 µA - Ensures minimal leakage-induced power waste and signal integrity degradation in high-temp environments. |
| trr | ≤3.0 µs - Enables use in <500 kHz rectification stages without excessive switching loss or EMI generation. |
| RθJT | 30 °C/W - Quantifies thermal path efficiency from junction to PCB pad; informs heatsinking requirements for sustained 1 A loads. |
Pinout & Package
S1BB-13 uses the SMB (DO-214AA) surface-mount plastic package: 4.06–4.57 mm length (B), 3.30–3.94 mm width (A), 1.96–2.21 mm height (C), cathode band marking on top surface. Terminals are matte tin-plated for lead-free soldering per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to AC source or transformer secondary; must handle full 1.0 A RMS and 30 A surge currents. |
| Cathode | Current exit point during forward conduction; marked with band | Routes rectified DC to bulk capacitor or regulator input; polarity-sensitive placement required for correct circuit operation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die construction | Eliminates need for hermetic sealing while maintaining >1000-hour HAST reliability; suitable for humid industrial environments. |
| Surge rating: 30 A IFSM (8.3 ms) | Withstands repeated cold-start surges in wall adapters and PoE-powered devices without parameter shift or failure. |
| RoHS-compliant, halogen/antimony-free "Green" finish | Meets EU Directive 2011/65/EU with Br+Cl <1500 ppm and Sb <1000 ppm; supports eco-labeling and export compliance. |
| Moisture sensitivity level 1 | Zero bake requirement before reflow; compatible with standard SMT assembly lines without dry-pack handling. |
Applications
| AC-DC Wall Adapters | Industrial DC Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBD101BLT1G | Lower VRRM (70 V), same SMB package, 1.0 A IO, but higher VFM (1.25 V typ) | Not suitable for 100 V line-derived inputs; limited to ≤50 V DC systems | Select only if VRRM margin is relaxed and cost is primary constraint. |
| Vishay VS-1N4007TR | Through-hole DO-41, 1000 V VRRM, 1.0 A IO, slower trr (>2 µs), no RoHS/Green compliance | Requires PCB real estate for axial leads; unsuitable for automated SMT lines | Choose only for legacy through-hole designs where 1000 V rating is mandatory and lead-free is not required. |
Compared with MMBD101BLT1G and VS-1N4007TR, S1BB-13 uniquely balances 100 V VRRM, SMB SMT compatibility, 30 A surge robustness, and full RoHS/Green compliance-making it optimal for modern, space-constrained, thermally demanding 24–48 V industrial and automotive power inputs.

FAQ
What is the maximum operating temperature for S1BB-13?
S1BB-13 has an operating and storage temperature range of –65°C to +150°C. Its thermal resistance (RθJT = 30°C/W) and 1.0 A current rating are specified at terminal temperature (TT) of +100°C, meaning sustained full-load operation requires adequate PCB copper area to maintain terminal temperature below that threshold.
Is S1BB-13 suitable for high-frequency switching applications?
No-S1BB-13 is a standard recovery rectifier with trr ≤ 3.0 µs, optimized for line-frequency (50/60 Hz) and low-frequency (<10 kHz) rectification. It is not recommended for high-frequency SMPS output stages where fast or ultrafast recovery diodes (trr < 50 ns) are required to minimize switching loss and EMI.
Does S1BB-13 have a qualified AEC-Q101 rating for automotive use?
No-S1BB-13 is commercially qualified (not AEC-Q101 stress-tested). However, its –65°C to +150°C operating range, 30 A surge rating, and SMB package robustness make it widely used in non-safety-critical automotive accessories (e.g., interior lighting, infotainment USB ports) where customer-level qualification suffices.
How does the SMB package of S1BB-13 compare to SMA in thermal performance?
S1BB-13's SMB package has identical RθJT (30°C/W) to the SMA variant when mounted on equivalent 5.0 mm² copper pads. However, SMB's larger body (4.3 mm width vs. SMA's 4.0 mm) provides slightly better mechanical stability and marginally improved heat spreading-though both require the same minimum pad layout per AP02001 for rated current handling.
