Taiwan Semiconductor Corporation S10GC

Overview

S10GC from Taiwan Semiconductor is a 10A, 400V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, 1.1V max forward voltage at 10A/25°C, 250A peak surge capability, and J-STD-020 Level 1 moisture sensitivity - used in high-efficiency AC/DC front-end stages of switching mode power supplies.

For engineers reviewing the S10GC datasheet, S10GC pinout, S10GC application, or S10GC equivalent, key selection criteria include repetitive peak reverse voltage (400V), thermal resistance (R_θJL = 10°C/W), junction temperature range (–55°C to +150°C), and RoHS/halogen-free compliance for industrial-grade power conversion designs.

Technical Context

The S10GC is a single-die, standard recovery rectifier optimized for high-current, medium-voltage DC output stages. Its glass-passivated junction ensures stable reverse leakage (<1 µA @ 25°C, <250 µA @ 125°C) and robust surge handling (250A, 8.3ms half-sine).

Thermally, it delivers R_θJL = 10°C/W and R_θJA = 47°C/W in standard PCB mounting, enabling reliable operation up to 150°C junction temperature with appropriate copper area and airflow - critical for compact SMPS and LED driver layouts.

FAQ

What is the maximum junction temperature rating for the S10GC?

The S10GC has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version D2102). This allows sustained operation in high-ambient environments such as enclosed LED drivers or industrial power supplies. Derating curves confirm usable current down to 0A at 150°C case temperature. The S10GC must be mounted on PCBs with sufficient copper area to maintain this limit under full 10A load.

Is the S10GC RoHS and halogen-free compliant?

Yes, the S10GC is fully RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the Taiwan Semiconductor product documentation (Version D2102). The molding compound and plating meet these requirements without exemptions. This makes the S10GC suitable for export to EU, Japan, and other regulated markets requiring strict material declarations. The S10GC carries no hazardous substance exceptions in its official compliance certification.

What does the "GC" suffix indicate in S10GC?

The "GC" suffix in S10GC designates the 400V repetitive peak reverse voltage (V_RRM) rating within the S10x family. Per the ordering table, "x" maps to voltage grade: GC = 400V, JC = 600V, KC = 800V, MC = 1000V. This coding is standardized across Taiwan Semiconductor's S10x rectifier series and appears as the marking code on the device body. The S10GC is not interchangeable with S10JC or S10MC without verifying circuit voltage stress margins.

What is the forward voltage drop of the S10GC at rated current?

The S10GC exhibits a maximum forward voltage drop (V_F) of 1.1 V at 10 A forward current and 25°C junction temperature, per electrical specifications in the Taiwan Semiconductor datasheet (Version D2102). This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating. At elevated temperatures (e.g., 125°C), V_F decreases slightly due to semiconductor physics, but system-level thermal design must still target ≤1.1 V to ensure efficiency targets are met. The S10GC's low V_F contributes directly to reduced conduction loss in high-duty-cycle applications.

Does the S10GC require a heatsink in typical applications?

The S10GC does not require an external heatsink in most applications when mounted on a standard 1-oz copper PCB with ≥100 mm² of thermal pad area connected to both anode and cathode terminals. Its R_θJL = 10°C/W enables effective heat transfer to the board, and R_θJA = 47°C/W reflects performance on JEDEC-standard test boards. However, in sealed enclosures or ambient temperatures above 70°C, thermal simulation using the S10GC's derating curve (Figure 1) is recommended. The S10GC's thermal performance is validated for convection-cooled SMT use without added mechanical heatsinks.
