Product details
Overview
S15GC M6G from Taiwan Semiconductor is a 15A, 400V surface-mount glass-passivated silicon rectifier diode in DO-214AB (SMC) package, featuring low forward voltage drop (1.1 V @ 15 A), high surge capability (350 A), and junction temperature rating up to 150°C - used in freewheeling paths and switching-mode power supplies for telecom and computing systems.
For engineers reviewing the S15GC M6G datasheet, S15GC M6G pinout, S15GC M6G application, or S15GC M6G equivalent, key selection factors include repetitive peak reverse voltage (400 V), thermal resistance (8 °C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and tape-and-reel packaging (3,000 pcs).
Technical Context
The S15GC M6G is a single-die, standard recovery rectifier optimized for high-current DC output stages and flyback diode roles in 60 Hz–100 kHz switching converters. Its glass-passivated junction ensures stable reverse leakage (<1 µA @ 25°C, <250 µA @ 125°C) and robust surge tolerance under 8.3 ms half-sine transients.
Thermally, it delivers RθJL = 8 °C/W and RθJA = 44 °C/W, enabling reliable operation at full 15 A average forward current with appropriate PCB copper area. Polarity is marked by a cathode band; terminals are matte tin-plated per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum non-repetitive reverse blocking voltage; defines safe operating limit in off-state |
| IF | 15 A - continuous average forward current at TA = 75°C with adequate heatsinking |
| IFSM | 350 A - peak non-repetitive surge current (8.3 ms half-sine); supports inrush and fault energy handling |
| VF | 1.1 V max @ 15 A, 25°C - directly impacts conduction loss and thermal design in high-current paths |
| RθJL | 8 °C/W - enables efficient heat transfer from die to PCB pad; critical for thermal reliability at full load |
| CJ | 93 pF @ 1 MHz, 4 V - affects high-frequency switching noise and snubber design in SMPS |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, molded plastic case meeting UL 94V-0; polarity indicated by cathode band; weight ≈ 0.270 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to lower-potential side of load or switch node; requires low-inductance layout for surge handling |
| Cathode (Lead 2) | Forward current exit / reverse-blocking terminal | Marked by band; ties to positive rail or output node; must withstand full VRRM during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term stability of reverse leakage and breakdown characteristics across temperature and humidity |
| Moisture sensitivity level 1 | Eliminates need for baking prior to reflow; compatible with standard SMT assembly without preconditioning |
| Matte tin-plated leads | Guarantees solderability per J-STD-002; supports lead-free reflow profiles without dewetting or voiding |
| J-STD-201 Class 2 whisker resistance | Prevents tin whisker growth under thermal cycling and long-term storage, enhancing field reliability |
Applications
| Telecom Power Supplies | Server DC-DC Converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1504D (STMicroelectronics) | 15 A, 400 V, TO-220AC package; VF = 1.15 V @ 15 A; RθJA = 40 °C/W (with heatsink) | Through-hole mounting; requires mechanical fastening and heatsink; not SMT-compatible | Select when board space permits through-hole layout and thermal management includes external heatsink |
| MBR1545CT (ON Semiconductor) | 15 A, 45 V Schottky; VF = 0.82 V @ 15 A; no reverse recovery; limited to ≤45 V applications | Lower VRRM precludes use in 400 V AC-line or high-voltage DC bus roles | Choose only for low-voltage, high-efficiency DC-DC outputs where reverse recovery loss dominates |
Compared with STTH1504D and MBR1545CT, the S15GC M6G uniquely balances SMT compatibility, 400 V blocking, and 15 A average current in a low-profile DO-214AB package - making it optimal for space-constrained, medium-voltage power conversion where thermal performance and assembly efficiency are jointly critical.

FAQ
What is the maximum junction temperature rating for the S15GC M6G?
The S15GC M6G has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating allows operation in high-ambient environments such as enclosed power supplies or industrial enclosures, provided thermal design maintains junction temperature below this limit. Derating curves confirm usable current capacity down to 0 A at 150°C ambient with no heatsink.
Is the S15GC M6G RoHS and halogen-free compliant?
Yes, the S15GC M6G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the manufacturer's documentation. The molding compound contains no brominated flame retardants or chlorine-based additives, and all plating and terminations meet EU Directive 2011/65/EU requirements without exemptions.
What does the "M6G" suffix indicate in S15GC M6G?
The "M6G" suffix in S15GC M6G denotes Taiwan Semiconductor's internal packaging and environmental code: "M" indicates tape-and-reel packaging (3,000 pcs/reel), "6" specifies green compound (halogen-free), and "G" confirms RoHS compliance. It does not alter electrical parameters - all specs match the base S15GC device defined in Version C2102.
Can the S15GC M6G replace the S15JC or S15KC in a design?
No - the S15GC M6G is rated for 400 V VRRM, while S15JC and S15KC are rated for 600 V and 800 V respectively. Substituting S15GC M6G in circuits requiring higher reverse blocking risks catastrophic failure during voltage transients. Only interchange within the same voltage grade (e.g., S15GC ↔ S15GC M6G) is electrically safe.
What is the typical junction capacitance of the S15GC M6G and how does it affect circuit design?
The S15GC M6G has a typical junction capacitance (CJ) of 93 pF measured at 1 MHz and 4.0 V reverse bias. This value influences high-frequency switching noise, EMI filter sizing, and snubber network design in SMPS. In 100 kHz converters, it contributes measurable displacement current during turn-off, requiring careful gate-drive and layout isolation to avoid false triggering.
