Product details

Overview

S10GC R7G from Taiwan Semiconductor is a 10A, 400V surface-mount glass-passivated silicon rectifier diode in DO-214AB (SMC) package, featuring low forward voltage drop (≤1.1 V at 10 A), high surge capability (250 A IFSM), and 150°C max junction temperature - deployed in AC/DC front-end stages of compact switching mode power supplies.

For engineers reviewing the S10GC R7G datasheet, S10GC R7G pinout, S10GC R7G application, or S10GC R7G equivalent, key selection factors include repetitive peak reverse voltage (400 V), thermal resistance (R_θJL = 10 °C/W), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance for automated SMT assembly in industrial adapters and LED drivers.

Technical Context

The S10GC R7G is a single-die, standard recovery rectifier optimized for high-efficiency, high-density SMPS input rectification. Its glass-passivated junction ensures stable reverse leakage (<1 µA at 25°C, <250 µA at 125°C) and robust surge tolerance under 8.3 ms half-sine stress.

Thermally, it delivers R_θJL = 10 °C/W to lead and R_θJA = 47 °C/W in free air, enabling reliable 10 A continuous operation with minimal heatsinking in DO-214AB footprint. Polarity is marked by cathode band; terminals are matte tin-plated per J-STD-002.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum non-repetitive reverse blocking voltage; defines safe operating limit in bridge or single-phase rectifier topologies
I_F	10 A - Continuous average forward current rating at T_A = 75°C; determines minimum trace width and thermal pad area
I_FSM	250 A - Peak non-repetitive surge current (8.3 ms); supports inrush withstand in offline converters
V_F	≤1.1 V @ 10 A, 25°C - Low conduction loss improves efficiency and reduces thermal load in high-current paths
R_θJL	10 °C/W - Junction-to-lead thermal resistance; enables direct thermal coupling to PCB copper for passive cooling
T_J max	150°C - Maximum allowable junction temperature; sets derating boundary for ambient and layout design
C_J	60 pF @ 1 MHz, 4 V - Junction capacitance impacts EMI filtering and switching node ringing in high-frequency designs

Equivalent & Alternatives

The following parts are listed as comparable options for similar rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH10R04DJF	400 V V_RRM, 10 A I_F, but fast recovery (t_rr ≈ 45 ns); higher V_F (1.3 V typ)	Better for high-frequency (>100 kHz) PFC stages where reverse recovery loss dominates	Select S10GC R7G for cost-sensitive, thermally constrained 50–65 kHz SMPS; STTH10R04DJF where EMI or efficiency at >100 kHz is critical
ON Semi MUR1040	400 V V_RRM, 10 A I_F, ultrafast recovery (t_rr = 50 ns); same DO-214AB package	Lower EMI in high-dv/dt environments due to faster soft recovery	S10GC R7G offers lower V_F and superior surge rating (250 A vs. 150 A); MUR1040 preferred only when t_rr is design-critical

Compared with STTH10R04DJF and MUR1040, the S10GC R7G prioritizes conduction efficiency and surge robustness over reverse recovery speed - making it optimal for cost-driven, thermally sensitive, and line-frequency-dominated rectification where low V_F and high I_FSM directly improve system reliability and BOM simplicity.

FAQ

What is the maximum junction temperature rating for the S10GC R7G?

The S10GC R7G has a maximum junction temperature (T_J) rating of +150°C. This value defines the upper thermal limit for reliable operation and must be respected in thermal design - including PCB copper area, airflow, and ambient conditions. Derating curves in the official datasheet show how average forward current decreases as case or ambient temperature rises above 25°C. The S10GC R7G maintains full 10 A rating only up to T_A = 75°C with adequate heatsinking.

Is the S10GC R7G pin-compatible with other devices in the S10x family?

Yes - all S10x devices (S10GC, S10JC, S10KC, S10MC) share identical DO-214AB (SMC) package dimensions, pinout, and thermal characteristics. The only difference is rated V_RRM: 400 V (S10GC R7G), 600 V (S10JC), 800 V (S10KC), and 1000 V (S10MC). Designers may substitute within the family without layout changes, provided voltage margin and surge requirements remain satisfied for the S10GC R7G application.

Does the S10GC R7G meet halogen-free and RoHS requirements?

Yes, the S10GC R7G is both RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. These certifications are verified in TSC's material declarations and supported by third-party test reports available upon request. The S10GC R7G is suitable for export to EU, Japan, and other regulated markets requiring full substance compliance.

What is the moisture sensitivity level (MSL) of the S10GC R7G, and how does it affect handling?

The S10GC R7G is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and requires no baking prior to reflow soldering. This eliminates moisture-related popcorning risk and simplifies SMT line integration - especially valuable in high-throughput manufacturing. The S10GC R7G can be stored indefinitely at ≤30°C/60% RH and processed using standard lead-free reflow profiles without preconditioning.

How does the forward voltage (V_F) of the S10GC R7G compare to similar 10 A rectifiers?

The S10GC R7G specifies V_F ≤ 1.1 V at I_F = 10 A and T_J = 25°C - among the lowest in its class. This compares favorably to alternatives like MUR1040 (1.25 V typ) and STTH10R04DJF (1.3 V typ). Lower V_F directly reduces conduction loss and die temperature rise, allowing smaller thermal pads or higher ambient operation. The S10GC R7G achieves this while maintaining 250 A surge rating and MSL Level 1 reliability.
