Product details

Overview

S3K M6G from Taiwan Semiconductor is a 800 V, 3 A surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 100 A surge current capability, 1.15 V max forward voltage at 3 A, and 10 µA max reverse leakage at 25°C - used in AC/DC front-end rectification for industrial switch-mode power supplies.

For engineers reviewing the S3K M6G datasheet, S3K M6G pinout, S3K M6G application, or S3K M6G equivalent, key selection criteria include repetitive peak reverse voltage (800 V), thermal resistance (13 °C/W junction-to-lead), reverse recovery time (1500 ns), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.

Technical Context

This single-die standard recovery rectifier operates with a maximum junction temperature of 150°C and exhibits a typical junction capacitance of 60 pF at 1 MHz and 4 V reverse bias. Its 1500 ns reverse recovery time reflects trade-off between switching loss and conduction efficiency in medium-frequency SMPS designs.

The device uses glass-passivated chip junction construction, matte tin-plated leads compliant with J-STD-002, and meets UL 94V-0 flammability rating. Polarity is indicated by cathode band; weight is 0.210 g.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L06S	600 V V_RRM, 120 ns t_rr, TO-277 package	Better for high-frequency PFC; lower voltage rating limits use to ≤425 V_AC inputs	Select when faster recovery is required and input voltage ≤240 V_AC
VS-3EYH06-M3	600 V V_RRM, 1.05 V V_F, DO-214AB, 50 A I_FSM	Lower conduction loss but reduced surge robustness; optimized for efficiency-critical adapters	Prefer for low-noise consumer adapters where surge margin is secondary

Compared with STTH3L06S and VS-3EYH06-M3, the S3K M6G delivers higher voltage margin (800 V) and superior surge handling (100 A), making it optimal for industrial-grade 230 V_AC mains input where reliability outweighs ultra-fast switching needs.

FAQ

What is the maximum junction temperature rating for the S3K M6G?

The S3K M6G has a maximum junction temperature (T_J) rating of +150°C, enabling reliable operation in enclosed industrial power supplies with limited airflow. This rating is validated per JEDEC JESD22-A108 and aligns with its 13 °C/W junction-to-lead thermal resistance. Derating curves in the official TSC datasheet confirm usable current capacity down to 1.8 A at 125°C ambient with minimal copper area.

Does the S3K M6G meet RoHS and halogen-free requirements?

Yes, the S3K M6G is RoHS compliant and halogen-free per IEC 61249-2-21 and IPC-1752A standards. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. This is confirmed in TSC's Declaration of Conformity (DOC) for the S3x series, revision O2301.

What is the reverse recovery time (t_rr) specification for the S3K M6G?

The S3K M6G has a reverse recovery time (t_rr) of 1500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value is typical for standard recovery rectifiers and suits 50–100 kHz switching frequencies in flyback and forward converters. It is not optimized for high-frequency PFC stages where <100 ns recovery is required.

Is the S3K M6G suitable for automated SMT assembly?

Yes, the S3K M6G is designed for automated placement with DO-214AB (SMC) package geometry, J-STD-020 Level 1 moisture sensitivity, and matte tin-plated leads solderable per J-STD-002. Its 0.210 g weight and symmetrical lead profile ensure stable pick-and-place yield above 99.95% at standard vision-guided feeders.

How does the S3K M6G compare to the S3M variant in terms of voltage rating?

The S3K M6G is rated for 800 V repetitive peak reverse voltage (V_RRM), while the S3M variant is rated for 1000 V. Both share identical package (DO-214AB), forward current (3 A), surge rating (100 A), and thermal characteristics. The S3K M6G offers optimal margin for 230 V_AC mains (325 V peak) with tighter process control than S3M, resulting in slightly lower V_F distribution.
