Product details
Overview
S8GC M6G from Taiwan Semiconductor is a surface-mount silicon rectifier diode rated for 8 A average forward current and 400 V repetitive peak reverse voltage in a DO-214AB (SMC) package. It features glass passivated junction, low forward voltage drop (max 0.985 V at 8 A), high surge capability (200 A @ 8.3 ms), and is RoHS- and halogen-free compliant. It is used in switching mode power supplies and AC/DC adapters.
For engineers reviewing the S8GC M6G datasheet, S8GC M6G pinout, S8GC M6G application, or S8GC M6G equivalent, key selection criteria include verified VRRM = 400 V, IF = 8 A, IFSM = 200 A (8.3 ms), TJMAX = 150 °C, and DO-214AB mechanical compatibility with automated SMT assembly.
Technical Context
The S8GC M6G is a single-die, standard recovery silicon rectifier optimized for medium-power AC/DC conversion. Its glass-passivated junction ensures stable reverse leakage (<10 µA at 25 °C, <250 µA at 125 °C) and robust surge tolerance under transient line conditions.
Thermal performance is defined by RθJL = 12.5 °C/W and RθJA = 44.0 °C/W, supporting conduction-cooled operation in compact power supplies. The cathode band marking and matte tin-plated leads comply with J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R04DJF | VRRM = 400 V, IF = 8 A, but ultrafast recovery (trr = 35 ns); higher VF (1.15 V typ) | Better suited for high-frequency PFC or ZVS circuits; not needed for standard 50/60 Hz rectification | Select S8GC M6G when cost, thermal robustness, and standard recovery timing are prioritized over switching speed |
| ON Semi MUR840 | VRRM = 400 V, IF = 8 A, soft-recovery profile; slightly higher VF (1.05 V max) and lower IFSM (175 A) | Preferred in EMI-sensitive lighting systems due to reduced switching noise | Choose S8GC M6G where surge margin (200 A vs. 175 A) and lower forward drop are critical for reliability |
Compared with STTH8R04DJF and MUR840, the S8GC M6G offers superior surge immunity and lower conduction loss at 8 A, making it optimal for cost-sensitive, thermally constrained offline power supplies where standard recovery timing is acceptable.

FAQ
What is the maximum junction temperature rating for the S8GC M6G?
The S8GC M6G has a maximum junction temperature (TJMAX) of +150 °C, enabling reliable operation in thermally demanding environments such as enclosed power adapters or industrial power modules. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version G2210). Derating curves show usable current capacity down to 0 A at 150 °C ambient with proper PCB heatsinking.
Does the S8GC M6G have a RoHS and halogen-free certification?
Yes, the S8GC M6G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the Features section of the Taiwan Semiconductor datasheet. The device uses green molding compound and meets J-STD-020 moisture sensitivity level 1, eliminating bake requirements prior to reflow soldering.
What is the forward voltage drop specification for the S8GC M6G at rated current?
The S8GC M6G has a maximum forward voltage drop (VF) of 0.985 V at IF = 8 A and TJ = 25 °C, measured under pulsed conditions (PW = 0.3 ms). This value is specified in the Electrical Specifications table and reflects low conduction loss critical for efficiency in 60–100 W power supplies.
Is the S8GC M6G pin-compatible with other devices in the S8x family?
Yes, all S8x devices-including S8GC M6G, S8JC, S8KC, and S8MC-share identical DO-214AB (SMC) packaging, pinout, and mechanical dimensions. Only the VRRM rating differs (400 V to 1000 V), allowing board-level voltage scalability without layout changes.
What is the surge current rating for the S8GC M6G, and under what test condition?
The S8GC M6G is rated for 200 A non-repetitive forward surge current (IFSM) under an 8.3 ms single half-sine wave at TJ = 25 °C. This rating is validated per JEDEC standards and supports robustness against cold-start inrush and line transients in universal-input power supplies.
