Taiwan Semiconductor Corporation S10KC R7G

Overview

S10KC R7G from Taiwan Semiconductor is a 10A, 800V 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 current capability (250 A), and junction temperature rating up to +150°C. It serves as the primary output rectifier in high-efficiency AC/DC converters for LED drivers and industrial power adapters.

For engineers reviewing the S10KC R7G datasheet, S10KC R7G pinout, S10KC R7G application, or S10KC R7G equivalent, key selection criteria include repetitive peak reverse voltage (800 V), thermal resistance (R_θJL = 10 °C/W), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance per IEC 61249-2-21.

Technical Context

The S10KC R7G implements a single-die, planar passivated junction structure optimized for fast recovery and low conduction loss in continuous forward-biased operation. Its 800 V V_RRM rating enables use in universal-input SMPS designs with ≥385 V DC bus, while the 250 A I_FSM supports robust line-transient handling without derating.

Thermal performance is defined by R_θJL = 10 °C/W and R_θJA = 47 °C/W under standard JEDEC test conditions, supporting board-level thermal design with copper pour on cathode pad. Polarity is unambiguously indicated by a molded cathode band per JEDEC DO-214AB mechanical standard.

FAQ

What is the maximum junction temperature rating for the S10KC R7G?

The S10KC R7G has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in Taiwan Semiconductor's D2102 datasheet. This allows sustained operation in industrial enclosures with ambient temperatures up to 85°C when properly mounted on ≥1 in² copper pour. The S10KC R7G must not be operated beyond this limit to ensure long-term reliability and avoid parametric drift.

Does the S10KC R7G meet RoHS and halogen-free requirements?

Yes, the S10KC R7G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the "Features" section of the official datasheet (Version D2102). The molding compound is UL 94V-0 rated, and terminals are matte tin-plated to J-STD-002 solderability standards. These certifications apply directly to the S10KC R7G, not just the family.

What is the forward voltage drop of the S10KC R7G at rated current?

The S10KC R7G exhibits a maximum forward voltage drop (V_F) of 1.1 V at 10 A and 25°C junction temperature, measured under pulsed conditions (PW = 0.3 ms). At elevated temperatures (125°C), V_F decreases slightly due to semiconductor physics, but the 1.1 V spec remains the design-limiting value for thermal calculations. This value is confirmed in the Electrical Specifications table for the S10KC R7G.

Is the S10KC R7G suitable for automated SMT assembly?

Yes, the S10KC R7G is explicitly designed for automated placement, as noted in its "Features" list. It uses the DO-214AB (SMC) package with matte tin-plated leads compliant with J-STD-002, and ships in 3,000-piece tape-and-reel format. Its MSL Level 1 rating means it can be used directly from dry pack without baking-critical for high-throughput SMT lines handling the S10KC R7G.

How does the S10KC R7G differ from the S10MC and S10GC variants?

The S10KC R7G is the 800 V variant in the S10x family: S10GC = 400 V, S10JC = 600 V, S10KC = 800 V, S10MC = 1000 V. All share identical package (DO-214AB), current rating (10 A), thermal specs (R_θJL = 10 °C/W), and marking format (S10xC). The S10KC R7G's 800 V V_RRM makes it optimal for universal-input SMPS with 385 V DC bus, distinguishing it electrically while maintaining full mechanical and assembly compatibility with other S10x devices.
