Product details
Overview
S15MC M6G from Taiwan Semiconductor is a 15A, 1000V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, 1.1V max forward voltage at 15A/25°C, 350A peak surge capability, and JESD201 Class 2 whisker resistance - used in high-reliability freewheeling and SMPS output stages.
For engineers reviewing the S15MC M6G datasheet, S15MC M6G pinout, S15MC M6G application, or S15MC M6G equivalent, key selection criteria include repetitive peak reverse voltage (1000V), thermal resistance (RθJL = 8°C/W), moisture sensitivity level (MSL 1), RoHS/halogen-free compliance, and tape-and-reel packaging for automated assembly.
Technical Context
The S15MC M6G is a single-die, unidirectional silicon rectifier optimized for high-current DC output rectification in switching power supplies and inverters. Its glass-passivated junction ensures stable reverse leakage (<1µA @ 25°C, <250µA @ 125°C) and robust surge tolerance (350A, 8.3ms half-sine).
Thermally, it delivers RθJL = 8°C/W and RθJA = 44°C/W under standard mounting conditions, enabling reliable operation up to TJ = 150°C. Polarity is marked by a cathode band on the DO-214AB body, with matte tin-plated leads compliant with J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - maximum repetitive reverse voltage; defines safe blocking capability in high-voltage DC bus applications |
| IF | 15 A - continuous average forward current; supports sustained conduction in 12–48V output rails of industrial SMPS |
| IFSM | 350 A - non-repetitive surge rating; withstands inrush and fault currents without bond-wire failure |
| VF (max) | 1.1 V @ 15A/25°C - low conduction loss; reduces thermal stress and improves efficiency in high-duty-cycle converters |
| RθJL | 8 °C/W - junction-to-lead thermal resistance; enables direct heat transfer to PCB copper or heatsink via cathode/anode pads |
| CJ | 93 pF @ 1MHz/4V - junction capacitance; impacts EMI behavior and snubber design in high-frequency switching circuits |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, dual-leaded, molded plastic case with UL 94V-0 rating and cathode band polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node); requires adequate copper area for thermal dissipation |
| Cathode (Lead 2) | Forward current exit / reverse blocking terminal | Marked by band; connects to output rail; serves as primary thermal path to PCB due to low RθJL |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable IR performance across temperature and humidity; eliminates need for conformal coating in humid environments |
| MSL Level 1 rating | Zero bake requirement before reflow; compatible with standard SMT assembly lines without moisture preconditioning |
| Matte tin-plated leads | Guarantees solder wetting per J-STD-002; prevents intermetallic voids during lead-free reflow (260°C peak) |
| RoHS + halogen-free | Meets IEC 61249-2-21; supports compliance-critical industrial and telecom equipment certifications |
Applications
| Industrial SMPS Output Rectification | Uninterruptible Power Supply (UPS) Inverter Stage |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1510DJF | 15A/1000V, TO-220AC package; higher RθJA (50°C/W), no MSL rating | Requires heatsink; unsuitable for high-density SMT-only layouts | Prefer when board space allows through-hole mounting and thermal mass is available |
| VS-15EWH10-M3 | 15A/1000V, DO-214AB; VF = 1.25V (max), RθJL = 9.5°C/W, MSL 1 confirmed | Slightly higher conduction loss; identical footprint and assembly compatibility | Select when tighter VF tolerance is not critical but second-source assurance is required |
Compared with STTH1510DJF and VS-15EWH10-M3, the S15MC M6G offers the lowest forward voltage (1.1V max) and best thermal coupling (RθJL = 8°C/W) in SMC package, making it optimal for compact, high-efficiency, and thermally constrained designs.

FAQ
What is the maximum junction temperature rating for the S15MC M6G?
The S15MC M6G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows continuous operation in enclosed industrial enclosures with ambient temperatures up to 85°C when mounted on ≥1 sq-in copper area. Derating curves in the S15MC M6G datasheet confirm usable current down to 7.5A at 125°C ambient.
Does the S15MC M6G meet J-STD-020 moisture sensitivity requirements?
Yes, the S15MC M6G is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and requires no baking prior to reflow. This is confirmed in the mechanical data section and supported by Taiwan Semiconductor's packaging process validation for DO-214AB molding compound.
What is the forward voltage specification for the S15MC M6G at elevated temperature?
The S15MC M6G specifies VF ≤ 1.1V at IF = 15A and TJ = 25°C. At TJ = 125°C, typical VF rises to ~0.95V due to negative temperature coefficient - a value confirmed in the "Typical Forward Characteristics" curve (Fig.4) of the S15MC M6G datasheet.
Is the S15MC M6G halogen-free and RoHS compliant?
Yes, the S15MC M6G uses halogen-free molding compound per IEC 61249-2-21 and is fully RoHS compliant (Pb-free, Cd-free, Hg-free, Cr⁶⁺-free, PBB/PBDE-free). This is explicitly stated in the FEATURES section and verified in Taiwan Semiconductor's material declaration report for S15MC M6G.
What does the "M6G" suffix indicate in S15MC M6G?
The "M6G" suffix in S15MC M6G denotes Taiwan Semiconductor's internal manufacturing code: "M" indicates DO-214AB (SMC) package, "6" specifies green compound (halogen-free), and "G" identifies the production lot and wafer fab. It does not affect electrical specs - all S15MC devices share identical VRRM, IF, and thermal parameters regardless of suffix.
