Product details
Overview
S4J R7G from Taiwan Semiconductor is a 4A, 600V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, 100A peak surge capability, 1.15V max forward voltage at 4A, and 10µA max reverse leakage at 25°C - used in AC/DC front-end rectification for industrial SMPS and LED drivers.
For engineers reviewing the S4J R7G datasheet, S4J R7G pinout, S4J R7G application, or S4J R7G equivalent, key selection criteria include repetitive peak reverse voltage (600V), thermal resistance (13°C/W junction-to-lead), moisture sensitivity level (MSL 1), RoHS/halogen-free compliance, and tape-and-reel packaging for automated assembly.
Technical Context
This single-die standard recovery rectifier operates with a 150°C maximum junction temperature and exhibits 1500ns reverse recovery time under IF = 0.5A, IR = 1.0A, Irr = 0.25A test conditions. Its 60pF junction capacitance at 1MHz/4V enables predictable high-frequency switching behavior in flyback and boost converters.
The device uses matte tin-plated leads compliant with J-STD-002 solderability and passes JESD201 Class 2 whisker testing. Polarity is marked by a cathode band on the DO-214AB molded case, which meets UL 94V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input rectification up to 424V RMS AC line voltage with safety margin |
| IF | 4 A continuous - sustains full-rated output current in 50–100W SMPS designs |
| IFSM | 100 A (8.3ms half-sine) - withstands inrush surges during cold-start of power supplies |
| VF | ≤1.15 V at 4A, 25°C - limits conduction loss to ≤4.6W per diode in high-current paths |
| IR | ≤10 µA at 600V, 25°C - ensures low standby power loss in offline adapters |
| RθJL | 13 °C/W - enables direct PCB copper pour heatsinking without external heatsink in <10W dissipation |
| trr | 1500 ns - compatible with 50–100kHz switching frequencies in cost-sensitive flyback topologies |

Applications
| Industrial SMPS Front-End | LED Driver Rectification |
|---|---|
Use Scenario: AC input rectification stage in 30–60W open-frame industrial switch-mode power supplies. IC Role / Device Role / Timing Role: Standard recovery rectifier converting 85–265V AC to unregulated DC bus. Use Value: 600V VRRM provides 1.5× margin over 400V peak line voltage; 13°C/W RθJL allows direct copper thermal relief on PCB. | Use Scenario: Output rectification in constant-current LED drivers for street lighting and high-bay fixtures. IC Role / Device Role / Timing Role: Secondary-side rectifier delivering stable DC to LED string with minimal conduction loss. Use Value: 1.15V VF at 4A reduces heat generation vs. higher-VF alternatives, improving driver efficiency and lumen maintenance. |
| AC/DC Adapter Input Stage | DC-DC Converter Input Protection |
Use Scenario: Primary rectification in universal-input wall adapters powering consumer electronics. IC Role / Device Role / Timing Role: Bridge or single-diode rectifier handling 50/60Hz mains input before PFC or PWM controller. Use Value: MSL Level 1 and J-STD-002 solderability ensure zero defects in high-volume SMT lines without process adjustments. | Use Scenario: Reverse-polarity and back-EMF protection at input of isolated DC-DC modules in battery-powered systems. IC Role / Device Role / Timing Role: Unidirectional blocking element preventing damage from accidental reverse connection or inductive kickback. Use Value: 100A IFSM clamps transient energy without failure; 10µA IR minimizes quiescent drain in always-on applications. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH4L06S | 4A, 600V, 1.15V VF, but faster trr = 75ns; TO-277 package (smaller footprint) | Better suited for >200kHz PFC stages where recovery loss dominates | Select STTH4L06S only if layout allows TO-277 and system demands lower EMI/noise |
| ON Semi MUR460 | 4A, 600V, 1.25V VF, trr = 75ns, DO-214AC (SMA) package - smaller than DO-214AB | Limited surge rating (60A vs. 100A); not recommended for high-inrush adapters | Choose MUR460 only for space-constrained, low-surge applications where 13°C/W thermal performance is not critical |
Compared with STTH4L06S and MUR460, the S4J R7G prioritizes robustness (100A surge, 13°C/W thermal path) over speed, making it optimal for cost-sensitive, thermally demanding 50–100kHz industrial rectification where reliability outweighs ultra-fast recovery.

FAQ
What is the maximum junction temperature rating for the S4J R7G?
The S4J R7G has a maximum junction temperature (TJ) of +150°C, allowing operation in high-ambient environments such as enclosed industrial power supplies or LED drivers with limited airflow. This rating is validated under steady-state thermal conditions and supports derating curves shown in Figure 1 of the S4A–S4M datasheet. The S4J R7G must be mounted on sufficient copper area to maintain TJ ≤ 150°C at full 4A load.
Does the S4J R7G meet RoHS and halogen-free requirements?
Yes, the S4J R7G is RoHS compliant and halogen-free per IEC 61249-2-21. This is confirmed in the "Features" section of the official Taiwan Semiconductor S4A–S4M datasheet (Version K2102). The molding compound and matte tin plating satisfy both environmental standards, making the S4J R7G suitable for export to EU, Japan, and other regulated markets.
What is the reverse recovery time (trr) specification for the S4J R7G?
The S4J R7G has a reverse recovery time (trr) of 1500 ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value is typical for standard recovery rectifiers and aligns with its intended use in 50–100kHz switching applications. The S4J R7G is not optimized for high-frequency PFC stages where fast or ultrafast recovery is required.
Is the S4J R7G suitable for automated SMT assembly?
Yes, the S4J R7G is designed for automated placement and reflow soldering. It carries MSL Level 1 per J-STD-020, requires no dry-pack or baking, and features matte tin-plated leads compliant with J-STD-002. Its DO-214AB (SMC) package and cathode band marking support reliable vision-based pick-and-place and AOI inspection in high-volume manufacturing of the S4J R7G.
What is the packaging configuration for the S4J R7G?
The S4J R7G is supplied in tape-and-reel format with 3,000 units per reel, as specified in the "Ordering Information" section of the Taiwan Semiconductor S4A–S4M datasheet. The DO-214AB (SMC) package dimensions and suggested pad layout are documented on page 5 of the same datasheet, ensuring compatibility with standard SMT stencil and placement equipment for the S4J R7G.
