Product details
Overview
S3GB R5G from Taiwan Semiconductor is a 3A, 600V standard surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring glass-passivated junction, 1.15V max forward voltage at 3A/25°C, 80A surge capability, and 150°C max junction temperature. It serves as the primary output rectifier in offline AC/DC power supplies for industrial adapters.
For engineers reviewing the S3GB R5G datasheet, S3GB R5G pinout, S3GB R5G application, or S3GB R5G equivalent, key selection criteria include repetitive peak reverse voltage (600V), forward current rating (3A), thermal resistance (10°C/W), reverse recovery time (1500ns), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
This standard recovery rectifier uses a single-die silicon PN junction with glass passivation for robustness against humidity and mechanical stress. Its 1500ns reverse recovery time and 10µA max reverse leakage at 25°C indicate suitability for non-critical switching applications below 100kHz.
The DO-214AA (SMB) package provides 10°C/W junction-to-lead thermal resistance and supports automated placement per J-STD-020 Level 1. Cathode polarity is marked by a visible band, and terminals are matte tin-plated for reliable solderability per J-STD-002.
Key Specifications

| IF | 3 A - Continuous average forward current under specified thermal conditions |
| IFSM | 80 A - Non-repetitive surge current capability for 8.3ms half-sine wave |
| VF (max) | 1.15 V @ 3A, 25°C - Forward conduction loss impacting efficiency and thermal design |
| IR (max) | 10 µA @ 600V, 25°C - Reverse leakage determining off-state power loss and system standby consumption |
| trr | 1500 ns - Recovery delay limiting usable switching frequency in SMPS designs |
| RθJL | 10 °C/W - Thermal resistance from junction to lead, critical for PCB copper pour sizing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V VRRM, 3A IF, but faster trr = 75ns; higher VF = 1.7V typical | Better suited for higher-frequency PFC stages where recovery loss dominates | Select STTH3L06S only if system operates >200kHz and thermal budget allows higher VF |
| SB360-E3/5BT | 60V VRRM (not 600V); same SMB package and 3A IF rating | Limited to low-voltage DC-DC outputs, not AC line rectification | SB360-E3/5BT is not a voltage-compatible alternative; use only in sub-100V secondary circuits |
Compared with STTH3L06S and SB360-E3/5BT, the S3GB R5G offers optimal balance of 600V blocking, 3A current handling, and cost-effective standard recovery performance for <100kHz offline SMPS-without requiring thermal derating or layout changes needed for ultrafast alternatives.

FAQ
What is the maximum junction temperature rating for the S3GB R5G?
The S3GB R5G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version M2102). This allows sustained operation in thermally constrained environments such as enclosed industrial power supplies. Derating curves confirm usable current down to 75°C ambient at full 3A load. The S3GB R5G must be mounted on adequate copper area to maintain this limit.
Does the S3GB R5G meet RoHS and halogen-free requirements?
Yes, the S3GB R5G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the "Features" section of the Taiwan Semiconductor datasheet (Version M2102). The molding compound is UL 94V-0 rated, and terminals are matte tin-plated without lead or brominated flame retardants. These compliance attributes are confirmed for the DO-214AA (SMB) packaged S3GB R5G unit.
What is the reverse recovery time (trr) specification for the S3GB R5G?
The S3GB R5G has a reverse recovery time (trr) of 1500 ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A per the Electrical Specifications table in the Taiwan Semiconductor datasheet (Version M2102). This value confirms its classification as a standard recovery rectifier, appropriate for flyback and forward converters operating up to ~100kHz-not for high-frequency synchronous rectification.
Is the S3GB R5G suitable for automated SMT assembly?
Yes, the S3GB R5G is optimized for automated placement: it carries J-STD-020 Level 1 moisture sensitivity, matte tin-plated leads compliant with J-STD-002, and DO-214AA (SMB) package geometry validated for pick-and-place accuracy. No pre-baking is required before reflow. The S3GB R5G's marking code "S3GB" and cathode band ensure orientation verification during AOI inspection.
What does the "R5G" suffix indicate in S3GB R5G?
The "R5G" suffix in S3GB R5G is Taiwan Semiconductor's internal date/batch code per their marking diagram (Version M2102): "R" denotes year code (2023), "5" is week code (Week 5), and "G" is factory identifier. It does not affect electrical specifications-the device remains functionally identical to S3GB with 600V VRRM, 3A IF, and DO-214AA packaging. All S3GB R5G units meet the same datasheet parameters.
