Product details
Overview
S1B R3G from Taiwan Semiconductor is a 1 A, 100 V surface-mount silicon rectifier diode in DO-214AC (SMA) package, featuring glass-passivated junction, 1.1 V max forward voltage at 1 A, 1 µA max reverse leakage at 25°C, and 1500 ns reverse recovery time - used in DC/DC converters and snubber circuits.
For engineers reviewing the S1B R3G datasheet, S1B R3G pinout, S1B R3G application, or S1B R3G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), thermal resistance (27 °C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and DO-214AC mechanical compatibility.
Technical Context
This standard recovery rectifier employs a single-die silicon PN junction with glass passivation for enhanced reliability and humidity resistance. Its 1500 ns reverse recovery time and 1.1 V forward voltage reflect trade-offs optimized for cost-sensitive, medium-frequency switching applications rather than ultra-fast or ultra-low VF operation.
The device operates across –55°C to +175°C junction temperature range and delivers 40 A non-repetitive surge current (8.3 ms half-sine). Thermal performance is defined by 27 °C/W junction-to-lead resistance, enabling direct PCB copper pad heat sinking without additional heatsinking in low-power designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse voltage the diode blocks reliably in circuit |
| IF | 1 A continuous - average forward current rating at TA = 25°C with adequate PCB copper area |
| VF | ≤1.1 V @ IF = 1 A, TJ = 25°C - determines conduction loss and self-heating under load |
| IR | ≤1 µA @ VR = 100 V, TJ = 25°C - defines leakage-induced standby power loss in high-impedance nodes |
| trr | 1500 ns - limits usable switching frequency in hard-switched topologies like flyback snubbers |
| RθJL | 27 °C/W - enables thermal design using only lead-to-PCB copper conduction, no external heatsink needed |
| MSL | Level 1 per J-STD-020 - allows unlimited floor life and standard reflow without dry-pack requirements |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, molded epoxy case with matte tin-plated leads; polarity indicated by cathode band; weight ≈ 0.060 g.

Key Features
| Feature | Design Value |
|---|---|

Applications
| DC/DC Converter | Snubber Circuit |
|---|---|
Use Scenario: Secondary-side rectification in isolated 5–24 V output flyback converters delivering ≤10 W. IC Role / Device Role / Timing Role: Unidirectional current steering element converting transformer AC output to regulated DC bus. Use Value: 1.1 V VF minimizes conduction loss at 1 A load; DO-214AC footprint supports automated placement and compact layout. | Use Scenario: RC snubber network across MOSFET drain-source in 60–100 kHz SMPS to suppress voltage spikes. IC Role / Device Role / Timing Role: Fast-recovery clamp path for transient energy dissipation during switching transitions. Use Value: 1500 ns trr balances cost and performance for medium-frequency snubbing; 100 V VRRM covers typical MOSFET VDS ratings. |
| Lighting Application | Switching Inverter |
Use Scenario: Input rectification stage in LED driver modules for commercial downlights (AC input, constant-current output). IC Role / Device Role / Timing Role: Bridge or single-diode AC line rectifier feeding bulk capacitor and PFC stage. Use Value: 175°C TJ max enables operation in thermally constrained luminaire enclosures; Level 1 MSL simplifies high-volume SMT assembly. | Use Scenario: Output rectification in low-power H-bridge inverters for fan or pump motor control (e.g., 24 V DC input → 50 Hz AC output). IC Role / Device Role / Timing Role: Half-wave or full-wave rectifier converting inverter AC output to DC for feedback sensing or auxiliary supply. Use Value: 40 A IFSM withstands startup surges; 27 °C/W RθJL allows direct thermal coupling to copper pour without thermal vias. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor M100S1 | VRRM = 100 V, VF = 1.05 V typ @ 1 A, trr = 1200 ns, same DO-214AC package | Slightly faster recovery and lower VF improve efficiency in higher-frequency designs | Preferred when <1300 ns trr or sub-1.1 V VF is required; identical footprint and solder profile |
| Vishay VS-1EWH01-M3/5A | VRRM = 100 V, VF = 1.15 V max @ 1 A, trr = 2000 ns, DO-214AC package, AEC-Q200 qualified | Designed for automotive-grade reliability; higher VF and slower trr suit lower-frequency, high-reliability use | Select for automotive lighting or industrial controls requiring AEC-Q200 stress testing and extended temperature validation |
Compared with M100S1 and VS-1EWH01-M3/5A, the S1B R3G offers balanced cost-performance for general-purpose 100 V rectification, with verified 27 °C/W thermal resistance and J-STD-020 Level 1 handling - making it optimal for high-volume consumer and industrial power supplies where strict automotive qualification is unnecessary.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for S1B R3G?
The S1B R3G has a VRRM of 100 V, meaning it reliably blocks up to 100 V of reverse voltage in repetitive operation. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version S2102), and applies across the full operating temperature range of –55°C to +175°C.
Does S1B R3G have a specified reverse recovery time (trr)?
Yes, the S1B R3G has a reverse recovery time of 1500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This parameter is explicitly listed in the Electrical Specifications section of the Taiwan Semiconductor S1A–S1M datasheet (Version S2102) and reflects its classification as a standard recovery rectifier.
Is S1B R3G compliant with RoHS and halogen-free standards?
Yes, the S1B R3G is RoHS compliant and halogen-free per IEC 61249-2-21. These compliance statements appear in the Features section of the official Taiwan Semiconductor datasheet (Version S2102), and are verified through material declarations and third-party test reports supporting the device's green electronics certification.
What is the thermal resistance from junction to lead (RθJL) for S1B R3G?
The junction-to-lead thermal resistance (RθJL) for S1B R3G is 27 °C/W, as specified in the Thermal Performance table of the Taiwan Semiconductor S1A–S1M datasheet (Version S2102). This value applies to S1A–S1J variants and enables accurate thermal modeling when the cathode/anode leads are soldered to sufficient PCB copper area.
What marking code identifies S1B R3G on the device body?
The S1B R3G is marked with "S1B" on the device body, per the Marking Diagram and Ordering Information sections of the Taiwan Semiconductor datasheet (Version S2102). The "R3G" suffix denotes tape-and-reel packaging (7,500 pcs/reel) and green compound; it does not appear on the physical marking.
