Product details
Overview
S3G M6G from Taiwan Semiconductor is a 400 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 switching mode power supplies.
For engineers reviewing the S3G M6G datasheet, S3G M6G pinout, S3G M6G application, or S3G M6G equivalent, key selection criteria include repetitive peak reverse voltage (400 V), average forward current (3 A), thermal resistance (RθJL = 13 °C/W), and RoHS/halogen-free compliance for industrial power adapter designs.
Technical Context
The S3G M6G is a single-die, glass-passivated junction standard recovery rectifier optimized for high-current, medium-voltage AC-to-DC conversion. Its 1500 ns reverse recovery time and 60 pF junction capacitance reflect trade-offs favoring low conduction loss over ultra-fast switching.
Designed for automated SMT placement, it meets J-STD-020 moisture sensitivity level 1 and JESD 201 class 2 whisker resistance. The cathode band polarity marking and matte tin-plated leads ensure reliable solderability per J-STD-002.

|---|---|
Use Scenario: 5–65 W universal-input wall adapters converting 85–265 VAC to low-voltage DC. IC Role / Device Role / Timing Role: Primary-side bridge or single-diode rectifier conducting full-wave or half-wave input current. Use Value: 400 V VRRM provides 2× safety margin over 265 VAC peak (375 V), while 3 A rating supports up to 65 W at 12 V output. | Use Scenario: Constant-current LED drivers for commercial lighting with offline rectified input. IC Role / Device Role / Timing Role: Input-stage rectifier feeding bulk capacitor and PFC or flyback controller. Use Value: 100 A surge rating withstands inrush into large input capacitors; 13 °C/W RθJL enables direct thermal coupling to PCB ground plane. |

Use Scenario: 100–300 W open-frame power supplies for PLCs, HMIs, and sensors. IC Role / Device Role / Timing Role: Output rectifier in isolated forward or push-pull topologies, or input rectifier in non-PFC designs. Use Value: 150°C max junction temperature allows operation in sealed enclosures up to 85°C ambient with minimal derating. | Use Scenario: Secondary-side rectification in isolated 12 V or 24 V DC-DC modules for embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L04S | 400 V, 3 A, 1.25 V VF (max), 1200 ns trr, DO-214AB | Higher VF increases conduction loss; faster trr reduces switching noise | Prefer when lower EMI is critical and thermal margin permits higher VF |
| MBR340F | 40 V, 3 A Schottky, 0.55 V VF (max), 100 ns trr, DO-214AB | Lower voltage rating limits use to ≤ 28 VAC inputs; negligible reverse recovery | Select only for low-VAC or DC-fed converters where 400 V blocking is unnecessary |
Compared with STTH3L04S and MBR340F, the S3G M6G delivers optimal balance of 400 V blocking, 3 A current, and cost-effective standard recovery performance for universal-input offline power stages - whereas STTH3L04S trades higher VF for faster recovery, and MBR340F sacrifices voltage rating for Schottky efficiency.

FAQ
What is the maximum junction temperature rating for the S3G M6G?
The S3G M6G has a maximum junction temperature (TJ) rating of +150°C, allowing operation in high-ambient environments such as enclosed industrial power supplies. This rating is specified across the full storage temperature range (−55°C to +150°C) and must be maintained using appropriate PCB copper area or heatsinking to limit RθJA to 47°C/W. Thermal design must ensure the S3G M6G junction stays below this limit under worst-case load and ambient conditions.
Does the S3G M6G have a halogen-free and RoHS-compliant construction?
Yes, the S3G M6G is both RoHS compliant and halogen-free, as confirmed in the official Taiwan Semiconductor documentation. The molding compound meets UL 94V-0 flammability standards, and the matte tin-plated leads satisfy J-STD-002 solderability requirements. These attributes make the S3G M6G suitable for consumer, industrial, and medical-adjacent applications where environmental compliance is mandatory.
What does the "M6G" suffix indicate in the S3G M6G part number?
The "M6G" suffix in S3G M6G is Taiwan Semiconductor's internal date code and factory identifier, not a functional variant. The core device is the S3G rectifier (400 V, 3 A), and all electrical, thermal, and mechanical specifications remain identical to the base S3G ordering code. The M6G marking appears on the device body alongside the "S3G" logo and cathode band per the DO-214AB package outline.
How is the polarity marked on the S3G M6G package?
The S3G M6G uses a cathode band - a distinct white or light-colored stripe near one end of the DO-214AB (SMC) body - to identify the cathode terminal. The unmarked end is the anode. This marking aligns with JEDEC DO-214 standard conventions and ensures correct orientation during PCB layout and automated placement. Polarity verification is critical, as reverse bias beyond 400 V will cause catastrophic failure.
What is the reverse recovery time (trr) specification for the S3G M6G?
The S3G M6G has a typical reverse recovery time (trr) of 1500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value reflects its standard recovery rectifier classification - optimized for conduction efficiency rather than high-frequency switching. Designers should account for this trr in EMI filtering and snubber sizing, especially in 50–100 kHz SMPS topologies.
