Product details
Overview
S3GHM6G from Taiwan Semiconductor is a 3A, 400V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, 100A non-repetitive surge capability, 1.15V max forward voltage at 3A, and 10µA max reverse leakage at 25°C - used in SMPS primary-side rectification and AC/DC adapter input stages.
For engineers reviewing the S3GHM6G datasheet, S3GHM6G pinout, S3GHM6G application, or S3GHM6G equivalent, key selection criteria include repetitive peak reverse voltage (400V), thermal resistance (13°C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and DO-214AB mechanical compatibility with automated placement.
Technical Context
This single-die standard recovery rectifier operates with a 150°C maximum junction temperature and exhibits 1500ns reverse recovery time under IF = 0.5A, IR = 1.0A, Irr = 0.25A test conditions. Its 60pF junction capacitance at 1MHz/4V enables stable high-frequency switching behavior in flyback and forward converter topologies.
The device delivers 3A average forward current with derating to zero at 150°C lead temperature, supported by 47°C/W junction-to-ambient thermal resistance. Cathode polarity is marked by a visible band on the molded body per JEDEC DO-214AB outline.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in bridge or single-diode rectifier configurations |
| IF(AV) | 3 A - Continuous DC forward current rating at 75°C lead temperature; determines heatsink sizing in power supply designs |
| IFSM | 100 A - Non-repetitive surge current for 8.3ms half-sine; supports inrush current handling during cold start |
| VF | ≤1.15 V @ 3A, 25°C - Forward voltage drop directly impacts conduction loss and thermal design in high-efficiency SMPS |
| IR | ≤10 µA @ 400V, 25°C - Low leakage ensures minimal standby power loss in offline adapters and lighting drivers |
| RθJL | 13 °C/W - Junction-to-lead thermal resistance enables direct thermal coupling to PCB copper for passive cooling |
| trr | 1500 ns - Reverse recovery time affects switching losses and EMI generation in 50–100kHz SMPS operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L04S | 400V VRRM, 3A IF, 1.25V VF max, 1250ns trr, TO-277 package | Higher VF increases conduction loss; faster trr reduces EMI but requires tighter layout | Preferred where lower EMI is prioritized and TO-277 footprint is available |
| MBR340 | 40V VRRM, 3A IF, Schottky structure, 0.55V VF max, no trr | Insufficient reverse voltage for 230VAC applications; limited to low-voltage DC-DC inputs | Only suitable for ≤60V DC input stages; not a functional replacement for S3GHM6G |
Compared with STTH3L04S and MBR340, the S3GHM6G offers optimal balance of 400V blocking, 1.15V VF, and DO-214AB compatibility for cost-sensitive AC/DC front-ends - whereas STTH3L04S trades higher VF for faster recovery, and MBR340 lacks required voltage rating entirely.

FAQ
What is the maximum junction temperature rating for S3GHM6G?
The S3GHM6G has a maximum junction temperature (TJ) rating of +150°C, with storage temperature range from –55°C to +150°C. This allows reliable operation in enclosed power supplies where ambient temperatures exceed 85°C, provided thermal design maintains junction temperature below this limit using the specified RθJL of 13°C/W.
Does S3GHM6G meet RoHS and halogen-free requirements?
Yes, the S3GHM6G is RoHS compliant and halogen-free per manufacturer documentation. It contains no brominated flame retardants or chlorine-based compounds, satisfying EU Directive 2011/65/EU and IPC-1752A material declaration requirements for environmentally regulated end equipment.
What is the reverse recovery time (trr) specification for S3GHM6G?
The S3GHM6G has a reverse recovery time (trr) of 1500 ns under standard test conditions (IF = 0.5A, IR = 1.0A, Irr = 0.25A). This value is measured per JEDEC JESD24-11 and reflects typical behavior for standard recovery rectifiers operating in 50–100kHz SMPS applications.
Is S3GHM6G suitable for use in high-humidity environments?
Yes, the S3GHM6G features a glass-passivated chip junction and meets J-STD-020 moisture sensitivity Level 1, enabling direct placement without baking. Its molded compound complies with UL 94V-0 flammability rating and resists delamination under 85°C/85% RH stress testing per JEDEC JESD22-A110.
What does the "S3G" marking on S3GHM6G indicate?
The "S3G" portion of S3GHM6G denotes the voltage grade within the S3A–S3M family: S3G corresponds to 400V repetitive peak reverse voltage (VRRM). The full ordering code S3GHM6G specifies DO-214AB (SMC) package, tape-and-reel packaging (6,000 pcs/reel), and green compound variant per TSC's internal coding system.
