Product details
Overview
S1B-13-F from Diodes Incorporated is a surface-mount, glass-passivated silicon rectifier diode in the SMB package, rated for 100 V peak repetitive reverse voltage (VRRM), 1.0 A average forward current (IO) at 100°C terminal temperature, and 30 A non-repetitive surge current (IFSM). It exhibits 1.1 V maximum forward voltage at 1.0 A and 3.0 μs maximum reverse recovery time (trr), making it suitable for general-purpose AC/DC conversion in compact power supplies.
For engineers reviewing the S1B-13-F datasheet, S1B-13-F pinout, S1B-13-F application, or S1B-13-F equivalent, key selection criteria include its SMB footprint compatibility, 100 V blocking capability, thermal resistance of 30 °C/W (junction-to-terminal), RoHS-compliant matte tin plating, and suitability for automated assembly in industrial and consumer power front-ends.
Technical Context
This device operates as a unidirectional, single-phase, half-wave rectifier with glass-passivated junction construction for enhanced reliability under transient stress. Its 30 A surge rating supports line-voltage input stages with high inrush tolerance, while the 1.1 V VF at 1.0 A balances conduction loss and thermal management in thermally constrained layouts.
The 3.0 μs maximum reverse recovery time (trr) and 10 pF typical junction capacitance (CT) indicate optimized switching behavior for 50/60 Hz and low-frequency (<100 kHz) rectification-distinct from fast or ultrafast recovery diodes intended for SMPS primary-side snubbing or freewheeling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum peak reverse voltage the diode blocks without breakdown; sets safe operating margin for 120 VAC inputs after derating. |
| IO @ TT=100°C | 1.0 A - Continuous DC output current achievable with 100°C terminal temperature; defines PCB copper pad heatsinking requirement. |
| VF @ IF=1.0A | 1.1 V max - Forward conduction loss at rated current; determines ~1.1 W worst-case power dissipation per diode. |
| IFSM (8.3 ms) | 30 A - Single half-sine surge current handling; enables robustness against cold-start inrush in transformer-based supplies. |
| trr | 3.0 μs max - Reverse recovery duration; limits switching losses and EMI generation in low-frequency rectifier applications. |
| RθJT | 30 °C/W - Thermal resistance from junction to terminal; requires ≥5 mm² copper pad per Diodes AP02002 for rated IO. |
| IR @ 125°C | 100 μA max - High-temperature leakage current; impacts standby power in always-on circuits. |
Pinout & Package
Package: SMB (Surface Mount Body), molded plastic case per JEDEC DO-214AA, UL 94V-0 rated, with cathode band polarity marking and matte tin–plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary winding; must withstand full surge current and reverse voltage during off-cycle. |
| Cathode | Forward current exit point | Connected to output capacitor or load; carries full DC output current and defines reference node for downstream filtering. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Eliminates passivation layer defects and moisture ingress paths, improving long-term reliability in humid or thermally cycled environments. |
| 30 A surge rating (8.3 ms) | Supports >20× rated current for brief transients-critical for transformer-coupled inputs with high magnetizing inrush. |
| RoHS-compliant, halogen- and antimony-free | Meets EU Directive 2011/65/EU and green manufacturing requirements (<900 ppm Br/Cl, <1000 ppm Sb). |
| SMB package with J-STD-020 Level 1 MSL | Enables standard reflow assembly without baking; compatible with high-volume SMT lines using 5.0 mm² copper thermal pads. |
Applications
| AC/DC Power Adapters | Industrial Control Power Supplies |
|---|---|
Use Scenario: 120 VAC input rectification in wall-wart adapters delivering 5–12 VDC to consumer electronics. IC Role / Device Role / Timing Role: Primary-side bridge or half-wave rectifier converting AC mains to pulsating DC before bulk capacitance and regulation. Use Value: 100 V VRRM provides 2× safety margin over 120 VAC peak (170 V), while 1.1 V VF minimizes heat buildup in sealed enclosures. | Use Scenario: Input rectification in DIN-rail mounted PLC power modules operating continuously at 40–60°C ambient. IC Role / Device Role / Timing Role: Unidirectional current path in linear or hybrid power supplies powering logic, I/O, and analog sensor circuitry. Use Value: 30 °C/W RθJT enables stable 1.0 A operation with minimal copper area, reducing PCB cost and size in space-constrained control cabinets. |
| LED Driver Input Stages | Appliance Motor Control Boards |
Use Scenario: Rectifying AC input to feed constant-current LED driver ICs in downlight and panel lighting fixtures. IC Role / Device Role / Timing Role: Front-end rectifier feeding bulk capacitor and PFC or buck controller; operates at line frequency only. Use Value: Low trr (≤3.0 μs) prevents excessive ringing and EMI during zero-crossing transitions, easing EMC compliance. | Use Scenario: Rectifying transformer output for relay coil drivers and triac gate supplies in washing machine or HVAC control boards. IC Role / Device Role / Timing Role: Isolated low-power DC rail generation for logic-level interface and optocoupler biasing. Use Value: 100 μA IR max at 125°C ensures negligible standby leakage across wide temperature ranges, preserving system sleep-mode integrity. |
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 MUR110EB | Ultrafast recovery (trr ≤ 50 ns), higher VF (1.3 V), same SMB package and 100 V rating. | Better suited for higher-frequency flyback snubbers; less optimal for pure 50/60 Hz rectification due to higher conduction loss. | Select when faster switching or reduced ringing is critical; avoid if minimizing conduction loss is priority. |
| Vishay VS-1EWH01-M3/5AT | Same 100 V/1.0 A rating, SMA package (smaller footprint), slightly higher VF (1.15 V), identical trr spec. | Requires PCB redesign for smaller pad layout; offers identical performance in space-constrained designs where SMB is oversized. | Choose for miniaturized layouts where SMB real estate is prohibitive; verify thermal pad area meets RθJT requirement. |
Compared with MUR110EB and VS-1EWH01-M3/5AT, S1B-13-F delivers the lowest conduction loss at 50/60 Hz while maintaining SMB mechanical compatibility and industry-standard thermal design rules-making it optimal for cost-sensitive, thermally managed line-frequency rectification.

FAQ
What is the maximum allowable junction temperature for S1B-13-F?
The absolute maximum junction temperature is +150°C, but continuous operation is specified up to +100°C terminal temperature. Derating curves show usable current drops to ~0.5 A at +125°C terminal temperature. Exceeding +150°C risks permanent parametric shift or bond wire failure.
Can S1B-13-F replace S1A-13-F in an existing design?
Yes-S1B-13-F (100 V) can directly replace S1A-13-F (50 V) if the circuit's peak reverse voltage remains below 100 V. No layout change is needed since both use the SMB package. However, verify that increased VRRM does not affect reverse recovery behavior or leakage in sensitive analog sections.
Is S1B-13-F suitable for use in a full-wave bridge configuration?
Yes-four S1B-13-F diodes can form a discrete full-wave bridge for 100 V-rated inputs. Each diode sees only half the peak inverse voltage of a center-tapped configuration, so the 100 V VRRM provides adequate margin for standard 120 VAC inputs (170 V peak).
Does S1B-13-F require a heatsink for 1.0 A operation?
No external heatsink is required if the PCB provides ≥5.0 mm² of 0.013 mm thick copper per Diodes AP02002. The 30 °C/W RθJT allows 1.0 A at 100°C terminal temperature with this pad area. Smaller copper areas will cause junction temperature to exceed limits under full load.
