Product details
Overview
S3JB 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 - used in AC/DC front-end rectification for industrial SMPS and lighting converters.
For engineers reviewing the S3JB R5G datasheet, S3JB R5G pinout, S3JB R5G application, or S3JB R5G equivalent, key selection criteria include repetitive peak reverse voltage (600V), forward current rating (3A), thermal resistance (10°C/W), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance for high-reliability power conversion designs.
Technical Context
This single-die standard recovery rectifier operates with a typical junction capacitance of 40pF at 1MHz/4V and exhibits 1500ns reverse recovery time under IF = 0.5A, IR = 1.0A, Irr = 0.25A conditions. Its glass-passivated chip junction ensures stable performance across -55°C to +150°C operating range.
The device uses matte tin-plated leads compliant with J-STD-002 solderability and meets JESD 201 Class 2 whisker resistance. Polarity is marked by cathode band on the DO-214AA (SMB) molded case rated UL 94V-0.

Applications
| LED Driver Power Supply | Industrial SMPS Front-End |
|---|---|
Use Scenario: Rectifying 50/60Hz AC input in constant-current LED drivers for street lighting and commercial fixtures. IC Role / Device Role / Timing Role: Primary AC-to-DC rectifier converting transformer secondary output to pulsating DC before bulk capacitor filtering. Use Value: 600V VRRM provides 2× safety margin over 230VAC line peaks; 3A rating supports up to 75W output with derating. | Use Scenario: Input rectification stage in 100–500W industrial switch-mode power supplies for PLCs and motor drives. IC Role / Device Role / Timing Role: Uncontrolled bridge or single-phase rectifier delivering DC bus voltage to PFC or main converter stage. Use Value: 80A IFSM withstands inrush surges during cold-start; 10°C/W RθJL enables compact heatsinkless layout at <2.5W dissipation. |
| AC/DC Adapter Secondary Side | DC-DC Converter Input Stage |
Use Scenario: Output rectification in isolated flyback adapters for consumer electronics (e.g., set-top boxes, routers). IC Role / Device Role / Timing Role: Secondary-side synchronous or standard rectifier converting high-frequency transformer output to regulated DC. Use Value: 1.15V VF minimizes conduction loss at 3A load; DO-214AA footprint allows automated placement and high-density PCB routing. | Use Scenario: Input rectification for non-isolated buck-derived DC-DC modules accepting wide-range DC inputs (e.g., 24–72V telecom rails). IC Role / Device Role / Timing Role: Pre-regulator rectifier handling variable DC input polarity reversal protection or bidirectional clamp functions. Use Value: 150°C TJ max and -55°C TSTG enable operation in harsh environments; 40pF CJ reduces EMI coupling in high-dV/dt switching nodes. |
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 (hyperfast); VF = 1.7V @ 3A | Better suited for high-frequency PFC or quasi-resonant converters where recovery loss dominates | Select STTH3L06S only if trr-driven efficiency gain outweighs higher conduction loss and cost premium |
| SB360-E3/5BT | 60V VRRM (not 600V); same SMB package, 3A IF, VF = 0.52V @ 3A, trr = 35ns | Limited to low-voltage DC-DC inputs; cannot replace S3JB R5G in AC-line applications | SB360-E3/5BT is not a voltage-compatible alternative; use only in ≤60V DC-fed circuits |
Compared with STTH3L06S and SB360-E3/5BT, the S3JB R5G delivers optimal balance of 600V blocking, low VF, and cost-effective standard recovery performance for line-frequency and medium-frequency SMPS where trr < 2µs is acceptable.

FAQ
What is the maximum junction temperature rating for the S3JB R5G?
The S3JB R5G has a maximum junction temperature (TJ) rating of +150°C, with a storage temperature range of -55°C to +150°C. This rating allows reliable operation in enclosed industrial enclosures and high-ambient lighting fixtures. Thermal design must ensure junction temperature remains below this limit under worst-case conduction and surge conditions. The S3JB R5G's 10°C/W junction-to-lead thermal resistance supports this rating when mounted on adequate copper area.
Is the S3JB R5G suitable for use in RoHS-compliant and halogen-free designs?
Yes, the S3JB R5G is fully RoHS compliant and halogen-free per IEC 61249-2-21. Its matte tin-plated leads, UL 94V-0 molding compound, and absence of brominated flame retardants meet stringent environmental requirements for export and commercial deployment. The S3JB R5G documentation explicitly confirms both certifications, making it suitable for green manufacturing programs without material declaration exceptions.
What does the "R5G" suffix indicate in the S3JB R5G part number?
The "R5G" suffix in S3JB R5G denotes Taiwan Semiconductor's internal reel packaging and environmental coding: "R5" indicates 3,000-piece tape-and-reel packaging per JEDEC standard, and "G" signifies green (halogen-free) compound. It does not affect electrical specifications - all S3JB variants share identical VRRM = 600V, IF = 3A, and thermal parameters. The base device remains functionally identical to S3JB without suffix.
How does the reverse recovery time of the S3JB R5G impact its use in switching power supplies?
The S3JB R5G has a reverse recovery time (trr) of 1500ns, characteristic of standard recovery rectifiers. In hard-switched SMPS operating below 100kHz, this value introduces minimal additional loss; however, above 50kHz, recovery-related switching losses and EMI may increase. For such cases, the S3JB R5G remains viable in cost-sensitive designs where efficiency trade-offs are acceptable. The S3JB R5G datasheet specifies trr under defined test conditions (IF = 0.5A, IR = 1.0A, Irr = 0.25A), enabling accurate loss modeling.
Can the S3JB R5G be used as a direct replacement for other S3x series rectifiers like S3KB or S3MB?
No - the S3JB R5G is rated for 600V VRRM and is not a direct replacement for S3KB (800V) or S3MB (1000V). While all share the same DO-214AA (SMB) package and pinout, voltage ratings are not interchangeable without system-level validation. Substituting a lower-VRRM device risks catastrophic failure under transient overvoltage. Always verify line surge margins and safety standards before cross-referencing within the S3AB–S3MB family. The S3JB R5G must be selected based on actual circuit peak reverse stress, not package compatibility alone.
