Product details
Overview
S1DB-13 from Diodes Incorporated is a surface-mount, glass-passivated general-purpose rectifier diode in SMB package, rated for 200 V peak repetitive reverse voltage (VRRM), 1.0 A average forward current (IO), and 30 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (1.1 V max at 1.0 A) and fast reverse recovery (1.8–3.0 μs), making it suitable for AC/DC input stage rectification in compact power supplies.
For engineers reviewing the S1DB-13 datasheet, S1DB-13 pinout, S1DB-13 application, or S1DB-13 equivalent, key selection criteria include its SMB footprint compatibility, thermal resistance (30 °C/W junction-to-terminal), 10 pF typical junction capacitance, and compliance with RoHS, halogen-free, and antimony-free "Green" standards.
Technical Context
This device operates as a single-phase, half-wave silicon rectifier optimized for commercial-grade switching power supplies and adapter front-end stages. Its glass-passivated die construction ensures high reliability under repeated surge stress, while the SMB package supports automated reflow assembly with J-STD-020 Level 1 moisture sensitivity.
The diode exhibits a maximum forward voltage of 1.1 V at 1.0 A and leakage current ≤5.0 μA at 25°C (≤100 μA at 125°C), enabling efficient operation across industrial ambient temperature ranges (–65°C to +150°C).
Key Specifications

| VRRM | 200 V - Withstands peak reverse transients up to 200 V without breakdown in AC line rectification |
| IO @ TT=100°C | 1.0 A - Continuous DC output current capability when mounted on PCB copper pad heat sink |
| IFSM (8.3 ms) | 30 A - Survives single half-sine surge events common in mains-powered equipment turn-on |
| VFM @ IF=1.0A | ≤1.1 V - Limits conduction loss and self-heating in high-duty-cycle rectifier applications |
| trr | 1.8–3.0 μs - Enables use in moderate-frequency (<100 kHz) SMPS without excessive switching loss |
| RθJT | 30 °C/W - Quantifies thermal path efficiency from junction to PCB pad; guides heatsinking decisions |
| CT @ 1 MHz | 10 pF - Low junction capacitance minimizes EMI generation and improves high-frequency noise immunity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MURS220T3G | Ultrafast recovery (trr = 35 ns), higher VRRM (200 V), same SMB package | Better suited for higher-frequency flyback or resonant converters where switching loss dominates | Select when trr < 50 ns required; avoid if cost sensitivity outweighs speed benefit |
| Vishay VS-1EQH02-M3/5AT | Higher IO (1.5 A), same VRRM (200 V), SMB package, but slower trr (≈150 ns) | Preferred for thermally constrained linear or low-frequency SMPS with higher average current demand | Choose when thermal headroom is limited and surge tolerance remains critical |
Compared with S1DB-13, MURS220T3G trades lower conduction loss for significantly faster recovery-ideal for >100 kHz designs-while VS-1EQH02-M3/5AT prioritizes current capacity and ruggedness over speed, better matching legacy 50/60 Hz or low-kHz rectifier needs.

FAQ
What is the maximum operating temperature for S1DB-13?
The S1DB-13 has an operating and storage temperature range of –65°C to +150°C. Its 1.0 A average forward current rating is specified at terminal temperature (TT) = +100°C, meaning sustained operation at full current requires adequate PCB copper heatsinking to maintain terminal temperature below this limit.
Is S1DB-13 compatible with lead-free reflow processes?
Yes. S1DB-13 features matte tin lead-free plating and is qualified for standard Pb-free reflow profiles per J-STD-020. Its Level 1 moisture sensitivity rating allows direct placement without pre-baking, simplifying SMT line integration.
How does the SMB package differ from SMA for S1DB-13?
S1DB-13 uses the SMB (DO-214AA) package, which is larger than SMA (DO-214AC): SMB measures 3.30–3.94 mm (L) × 4.06–4.57 mm (W) vs. SMA's 2.29–2.92 mm × 4.00–4.60 mm. SMB offers higher thermal mass and 30% greater current-handling margin, reflected in identical IO rating but improved surge robustness.
Can S1DB-13 replace S1D-13 in existing designs?
Yes, S1DB-13 is the SMB-package variant of S1D-13 (SMA package), sharing identical electrical specifications (VRRM = 200 V, IO = 1.0 A, etc.). Mechanical redesign is required due to different footprint and thermal pad layout, but no circuit changes are needed for functional equivalence.
