Product details
Overview
S5G R7G from Taiwan Semiconductor is a 5 A, 400 V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.15 V max forward voltage at 5 A and 100 A peak surge current capability; used in SMPS secondary-side rectification and AC/DC adapter output stages.
For engineers reviewing the S5G R7G datasheet, S5G R7G pinout, S5G R7G application, or S5G R7G equivalent, key selection criteria include repetitive peak reverse voltage (400 V), thermal resistance (13 °C/W junction-to-lead), reverse recovery time (1500 ns), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
The S5G R7G is a single-die, glass-passivated standard recovery rectifier optimized for high-current, medium-voltage switching power supplies. Its 150 °C maximum junction temperature and 47 °C/W junction-to-ambient thermal resistance support operation under sustained load in compact layouts.
It exhibits 60 pF junction capacitance at 1 MHz and 4 V reverse bias, with reverse leakage limited to 10 µA at 25 °C and 250 µA at 125 °C - enabling stable performance across industrial ambient conditions without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - supports input rectification up to 280 VAC RMS with safety margin |
| IF | 5 A continuous - delivers full-rated output current in 12–24 V DC/DC converter secondaries |
| IFSM | 100 A (8.3 ms) - withstands inrush surges during cold-start of LED drivers and adapters |
| VF | ≤1.15 V @ 5 A, 25°C - limits conduction loss to ≤5.75 W per device at full load |
| trr | 1500 ns - compatible with <100 kHz switching topologies; not suitable for >200 kHz ZVS/ZCS designs |
| RθJL | 13 °C/W - enables direct PCB copper pour heatsinking without external heatsink in ≤3 W dissipation |
| MSL | Level 1 (J-STD-020) - allows unlimited floor life and standard reflow without baking |
Pinout & Package
Package: DO-214AB (SMC), molded epoxy case meeting UL 94V-0; matte tin-plated leads; cathode indicated by band; weight ≈0.210 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input terminal for forward conduction | Connected to transformer secondary or bridge output; requires ≥1.5 mm creepage clearance at 400 V |
| Cathode (Lead 2) | Output terminal for forward conduction | Connected to output capacitor; polarity band must align with PCB silkscreen and layout |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Prevents moisture-induced degradation and ensures long-term reliability in humid environments |
| Low VF (≤1.15 V) | Reduces power loss by ≥12% vs. comparable 5 A rectifiers with VF >1.3 V at same current |
| High IFSM (100 A) | Eliminates need for parallel devices in 60 W+ adapter outputs subject to line-dip recovery surges |
| RoHS & halogen-free | Meets IEC 61249-2-21 and EU Directive 2011/65/EU for green electronics manufacturing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06 (STMicroelectronics) | 600 V VRRM, 1.7 V VF @ 5 A, faster trr (75 ns), TO-220AC package | Higher voltage margin but higher conduction loss; through-hole mounting only | Select when >400 V transient immunity required and board space permits larger package |
| ES5D (ON Semiconductor) | 200 V VRRM, 1.15 V VF @ 5 A, DO-214AB, 50 A IFSM | Lower voltage rating and surge capacity; identical footprint and soldering profile | Choose only for 120 VAC-input systems where 400 V rating is unnecessary and cost is critical |
Compared with STTH5L06 and ES5D, the S5G R7G uniquely balances 400 V rating, low VF, SMC packaging, and 100 A surge tolerance - making it optimal for global-input 48–60 V output adapters and LED drivers requiring automated assembly and industrial-grade reliability.

FAQ
What is the maximum junction temperature rating for the S5G R7G?
The S5G R7G has a maximum junction temperature (TJ MAX) of +150 °C, allowing operation in high-ambient environments such as enclosed LED luminaires or industrial power modules. This rating is validated per JEDEC JESD22-A104 and supported by its 13 °C/W junction-to-lead thermal resistance. Derating curves in the S5G R7G datasheet confirm usable current down to 70 °C ambient at full 5 A DC load.
Does the S5G R7G meet RoHS and halogen-free requirements?
Yes, the S5G R7G is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. These certifications are confirmed in Taiwan Semiconductor's official product change notices and material declarations. The S5G R7G uses bromine-free flame-retardant molding compound and lead-free matte tin plating on all terminals.
What is the reverse recovery time (trr) specification for the S5G R7G?
The S5G R7G has a typical reverse recovery time (trr) of 1500 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is measured per JEDEC JESD24-11 and applies directly to the S5G R7G - not extrapolated from adjacent S5x variants. It indicates suitability for ≤100 kHz switching frequencies in non-synchronous rectifier designs.
Is the S5G R7G suitable for use in high-humidity environments?
Yes, the S5G R7G is suitable for high-humidity environments due to its glass-passivated chip junction and J-STD-020 Level 1 moisture sensitivity rating, which permits unlimited floor life before reflow. Its UL 94V-0 epoxy molding compound further prevents moisture ingress, and qualification testing confirms stable IR performance (<250 µA at 125 °C) after 85 °C/85% RH bias stress.
What marking code appears on the S5G R7G device body?
The S5G R7G is marked with "S5G" on the device body, followed by a green compound indicator (G), date code (YW), and factory code (F), per Taiwan Semiconductor's standard DO-214AB marking diagram. The cathode band is clearly visible adjacent to the marking, confirming polarity orientation during automated optical inspection (AOI) and manual placement.
