Product details
Overview
S5B R7G from Taiwan Semiconductor is a 5A, 100V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, low forward voltage drop (max 1.15V at 5A), and high surge current capability (100A, 8.3ms). It serves as primary AC/DC input rectification in compact power adapters and offline SMPS.
For engineers reviewing the S5B R7G datasheet, S5B R7G pinout, S5B R7G application, or S5B R7G equivalent, key selection criteria include repetitive peak reverse voltage (100V), thermal resistance (RθJL = 13°C/W), junction capacitance (60pF), and moisture sensitivity level (MSL 1).
Technical Context
The S5B R7G is a single-die, standard recovery rectifier with 1500ns reverse recovery time under IF = 0.5A / IR = 1.0A test conditions. Its DO-214AB (SMC) package supports automated placement and meets UL 94V-0 flammability rating.
It operates across -55°C to +150°C junction temperature range, with maximum average forward current of 5A and peak non-repetitive surge current of 100A. Reverse leakage is rated ≤10µA at 25°C and ≤250µA at 125°C under rated VR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input voltage headroom in bridge or single-diode rectifier stage |
| IF | 5 A - Continuous average forward current; determines heatsink-free operation up to ~1.5W dissipation at typical VF |
| IFSM | 100 A - Peak non-repetitive surge current (8.3ms half-sine); enables robustness against line transients and inrush |
| VF | ≤1.15 V @ 5A, 25°C - Forward voltage drop directly impacts conduction loss and thermal load in high-duty-cycle applications |
| trr | 1500 ns - Reverse recovery time affects switching loss and EMI in higher-frequency SMPS designs above ~50kHz |
| RθJL | 13 °C/W - Junction-to-lead thermal resistance; enables direct PCB copper pour heat sinking without external heatsink |
| MSL | Level 1 - No floor life limitation; supports unlimited exposure to ambient humidity prior to reflow |
Pinout & Package
Package: DO-214AB (SMC), molded plastic case with matte tin-plated leads, cathode indicated by band. Weight: 0.210g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to AC input or transformer secondary; must withstand full surge current and thermal cycling |
| Cathode (Lead 2) | Forward current exit / reverse blocking terminal | Connected to bulk capacitor or output rail; polarity band ensures correct orientation during automated placement |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances long-term reliability and moisture resistance without requiring conformal coating in humid environments |
| Low VF (≤1.15V) | Reduces conduction losses by ~15% vs. comparable 100V rectifiers with VF > 1.3V, improving efficiency in 5–12W adapters |
| High IFSM (100A) | Withstands cold-start surges in universal-input (85–265VAC) SMPS without degradation over 100k+ cycles |
| DO-214AB (SMC) package | Enables 5A current handling in footprint smaller than TO-220 while supporting JEDEC-compliant reflow profiles |
Applications
| AC/DC Adapters | LED Drivers |
|---|---|
Use Scenario: Universal-input (85–265VAC), 5–12W wall plug adapters for consumer electronics. IC Role / Device Role / Timing Role: Input bridge rectifier diode in single-phase full-wave configuration.

IC Role / Device Role / Timing Role: Secondary-side rectifier in flyback or buck-derived topologies operating at 50–100kHz. Use Value: 1500ns trr limits switching loss and EMI generation when paired with 65kHz controllers like UCC28704. |
| Industrial Power Supplies | USB-C PD Chargers |

Use Value: Matte tin-plated leads ensure solder joint integrity after multiple reflow cycles during multi-layer board assembly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06 (STMicroelectronics) | 600V VRRM, 5A IF, 1.7V VF max, 75ns trr, TO-220AC package | Higher voltage rating but significantly higher VF and faster recovery; requires heatsink at full load | Select for higher-voltage legacy designs where fast recovery reduces EMI, but avoid in space-constrained adapters |
| MBR5100CT (ON Semiconductor) | 100V VRRM, 5A IF, 1.2V VF max, Schottky construction, TO-220AB package | Lower VF but limited to 125°C TJ; not suitable for 150°C ambient or high-surge environments | Prefer for low-loss, low-temperature applications; reject where surge immunity or extended temperature margin is required |
Compared with STTH5L06 and MBR5100CT, the S5B R7G offers optimal balance of surge robustness (100A), thermal margin (150°C), and surface-mount compatibility-making it preferred for compact, high-reliability 100V rectification where Schottky limitations or through-hole constraints apply.

FAQ
What is the maximum junction temperature rating for the S5B R7G?
The S5B R7G has a maximum junction temperature (TJ) rating of +150°C, with operational range from -55°C to +150°C. This allows reliable use in sealed enclosures or high-ambient environments such as LED driver housings or industrial control panels. The S5B R7G maintains specified electrical parameters within this full range, and its RθJL of 13°C/W supports effective thermal transfer to PCB copper.
Does the S5B R7G meet RoHS and halogen-free requirements?
Yes, the S5B R7G is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002 solderability standards. These certifications are confirmed in Taiwan Semiconductor's official documentation for the S5x family, including the S5B R7G variant.
What does the 'R7G' suffix indicate in S5B R7G?
The 'R7G' suffix in S5B R7G denotes Taiwan Semiconductor's internal date code and process revision: 'R7' indicates week 7 of 2023 (or 2033), and 'G' identifies the green compound variant per their material specification. This marking aligns with the S5x family's standardized DO-214AB packaging and does not affect electrical parameters-S5B R7G retains identical VRRM, IF, and trr ratings as base S5B.
Can the S5B R7G replace a 1N5408 in a PCB design?
No-the S5B R7G is a surface-mount DO-214AB device, while the 1N5408 is through-hole DO-201AD. Though both are 3A/1000V rectifiers, the S5B R7G is rated for 5A continuous and uses different thermal and mechanical interfaces. Direct replacement would require PCB redesign. For drop-in alternatives, consider SMB-type equivalents like SB5100, not S5B R7G.
Is the S5B R7G suitable for high-frequency switching applications above 100kHz?
The S5B R7G has a reverse recovery time (trr) of 1500ns, making it suitable for line-frequency and low-to-mid frequency SMPS (≤65kHz), but not recommended for high-frequency resonant or GaN-based topologies (>100kHz) where fast recovery or ultrafast diodes (<100ns) are required. In such cases, the S5B R7G may increase switching loss and EMI-use only where its 100A surge rating and thermal robustness outweigh speed limitations.
