Taiwan Semiconductor Corporation S10GC V7G

Overview

S10GC V7G from Taiwan Semiconductor is a 10A, 400V surface-mount glass-passivated silicon rectifier diode in DO-214AB (SMC) package, featuring 1.1V max forward voltage at 10A/25°C, 250A peak surge capability, and 150°C maximum junction temperature - deployed in AC/DC front-end stages of compact switching mode power supplies.

For engineers reviewing the S10GC V7G datasheet, S10GC V7G pinout, S10GC V7G application, or S10GC V7G equivalent, key selection criteria include repetitive peak reverse voltage (400V), thermal resistance (R_θJL = 10°C/W), moisture sensitivity level (MSL 1), RoHS/halogen-free compliance, and tape-and-reel packaging for automated assembly.

Technical Context

The S10GC V7G is a single-die, standard recovery rectifier optimized for high-efficiency, space-constrained AC/DC conversion. Its glass-passivated junction ensures stable reverse leakage (<1 µA @ 25°C, <250 µA @ 125°C) and robust surge tolerance (250A I_FSM, 8.3ms half-sine).

Thermally, it delivers R_θJL = 10°C/W and R_θJA = 47°C/W under standard PCB mounting, supporting continuous 10A conduction with appropriate copper area. Polarity is marked by a cathode band; terminals are matte tin-plated per J-STD-002.

FAQ

What is the maximum junction temperature rating for the S10GC V7G?

The S10GC V7G has a maximum junction temperature (T_J) of +150°C, with operational range from –55°C to +150°C. This rating enables reliable use in enclosed power supplies and high-ambient environments. Derating curves in the official datasheet specify allowable average forward current versus case temperature - for example, sustained 10 A operation requires case temperature ≤80°C under typical PCB conditions. The S10GC V7G must not exceed this limit to ensure long-term reliability.

Is the S10GC V7G compatible with lead-free reflow soldering processes?

Yes, the S10GC V7G is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its MSL Level 1 classification means it can be stored indefinitely at ambient conditions without baking prior to reflow. The device supports peak reflow temperatures up to 260°C per JEDEC J-STD-020, and its UL 94V-0 molding compound remains stable throughout standard Pb-free thermal profiles. The S10GC V7G is qualified for high-yield SMT assembly.

What does the 'V7G' suffix indicate in S10GC V7G?

The 'V7G' suffix in S10GC V7G denotes Taiwan Semiconductor's internal date/batch code: 'V' indicates manufacturing year (2025), '7' is the calendar week (week 7), and 'G' is the factory code. It does not affect electrical specifications - all S10GC devices share identical absolute maximum ratings, electrical characteristics, and mechanical dimensions regardless of suffix. The S10GC V7G performs identically to other S10GC units in the same revision (D2102).

How does the S10GC V7G compare to the S10JC in terms of voltage rating and application suitability?

The S10GC V7G is rated for 400 V V_RRM, while the S10JC is rated for 600 V V_RRM. Both share identical I_F (10 A), I_FSM (250 A), package (DO-214AB), and thermal specs. The S10GC V7G is ideal for universal-input (85–265 VAC) applications where 400 V provides sufficient margin; the S10JC suits higher-line applications like 3-phase rectification or 277 VAC lighting. Substituting S10GC V7G for S10JC risks reverse breakdown above 400 V.

Does the S10GC V7G have a specified junction capacitance, and how does it impact high-frequency designs?

Yes, the S10GC V7G has a typical junction capacitance (C_J) of 60 pF measured at 1 MHz and 4.0 V reverse bias. This value influences switching losses and EMI generation in high-frequency converters (>100 kHz). At light loads, C_J contributes to reverse recovery tail current; designers should verify snubber requirements using the S10GC V7G's published reverse recovery time (t_rr) and charge (Q_rr) data. The S10GC V7G's C_J is consistent across production lots per D2102 specification.
