Product details
Overview
S8MC M6G from Taiwan Semiconductor is an 8A, 1000V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass passivated junction, 0.985V max forward voltage at 8A/25°C, 200A surge rating (8.3ms), and J-STD-020 Level 1 moisture sensitivity - used in high-efficiency AC/DC front-end stages of industrial SMPS.
For engineers reviewing the S8MC M6G datasheet, S8MC M6G pinout, S8MC M6G application, or S8MC M6G equivalent, key selection criteria include repetitive peak reverse voltage (1000V), thermal resistance (RθJL = 12.5°C/W), junction temperature range (–55°C to +150°C), and RoHS/halogen-free compliance for regulated power systems.
Technical Context
This single-die standard recovery rectifier operates with a maximum junction temperature of 150°C and exhibits 10µA reverse leakage at 25°C and rated VRRM. Its 48pF junction capacitance at 1MHz/4V enables stable switching behavior in 50–100kHz SMPS topologies.
The device uses matte tin-plated leads compliant with J-STD-002 solderability and meets JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band on the molded DO-214AB body, and the 0.270g weight supports automated pick-and-place handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - blocks full-wave rectified line voltage up to 707V RMS without breakdown |
| IF | 8 A continuous - supports output power up to ~1 kW in 12V/8A DC bus designs |
| IFSM (8.3ms) | 200 A - withstands inrush surges during cold-start of offline converters |
| VF @ 8A/25°C | ≤0.985 V - limits conduction loss to ≤7.88 W per diode at full load |
| RθJL | 12.5 °C/W - enables direct PCB copper pour heat sinking without heatsink |
| Junction capacitance | 48 pF @ 1 MHz/4 V - minimizes high-frequency switching noise coupling in flyback snubbers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8L06W (STMicroelectronics) | 600V VRRM, 8A, ultrafast recovery (trr = 35ns), TO-220AC package | Lower voltage rating; faster switching but higher VF (1.15V); through-hole mounting | Select when fast recovery and thermal mass outweigh surface-mount constraints and voltage headroom needs |
| VS-8EWH10FN-M3 (Vishay) | 1000V VRRM, 8A, standard recovery, DO-214AB, VF = 0.99V max at 8A | Nearly identical electrical specs and package; slightly higher RθJA (50°C/W vs. 44°C/W) | Drop-in alternative where Taiwan Semiconductor supply continuity is constrained; verify layout thermal relief compatibility |
Compared with STTH8L06W, S8MC M6G offers 67% higher voltage margin and SMT compatibility; versus VS-8EWH10FN-M3, it delivers lower junction-to-ambient thermal resistance, enabling higher sustained power in compact layouts.

FAQ
What is the maximum repetitive peak reverse voltage rating for S8MC M6G?
The S8MC M6G has a maximum repetitive peak reverse voltage (VRRM) of 1000 V, verified per JEDEC test conditions. This rating ensures reliable blocking of transient overvoltages in universal-input 85–265VAC systems and provides sufficient margin against line spikes. The value is explicitly defined in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet revision G2210.
Does S8MC M6G require pre-reflow baking before assembly?
No, S8MC M6G does not require pre-reflow baking because it is rated at Moisture Sensitivity Level 1 per J-STD-020. This means the device can be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without desiccant or baking steps - simplifying SMT line logistics and reducing process risk for high-volume production of S8MC M6G-based power supplies.
What is the forward voltage drop of S8MC M6G at its rated current?
The forward voltage drop (VF) of S8MC M6G is guaranteed ≤0.985 V at IF = 8 A and TJ = 25°C, measured under pulsed conditions (PW = 0.3 ms). At elevated junction temperatures (e.g., 125°C), VF decreases slightly due to negative temperature coefficient - a characteristic confirmed in the Typical Forward Characteristics curve of the S8MC M6G datasheet.
Can S8MC M6G replace S8KC in an existing design?
S8MC M6G can replace S8KC only if the design requires ≥800V VRRM headroom - S8MC M6G offers 1000V vs. S8KC's 800V. Both share identical DO-214AB packaging, pinout, and thermal performance. However, designers must verify that system-level surge and insulation requirements justify the higher voltage rating, as no change in PCB layout or thermal design is needed for the swap.
Is S8MC M6G certified as halogen-free and RoHS compliant?
Yes, S8MC M6G is certified halogen-free per IEC 61249-2-21 and RoHS compliant per EU Directive 2011/65/EU. These declarations are documented in Taiwan Semiconductor's material compliance reports and reflected in the device marking ('G' suffix denotes green compound). No brominated flame retardants or chlorine-based additives are used in the molding compound.
