Product details

Overview

S15KC M6G from Taiwan Semiconductor is a 15A, 800V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.1V max forward voltage at 15A, 350A peak surge current, and 8°C/W junction-to-lead thermal resistance-used in freewheeling paths of switching-mode power supplies for telecom and computing equipment.

For engineers reviewing the S15KC M6G datasheet, S15KC M6G pinout, S15KC M6G application, or S15KC M6G equivalent, key selection criteria include V_RRM = 800V, I_F = 15A continuous, I_FSM = 350A (8.3ms), T_J = –55°C to +150°C, and DO-214AB mechanical compatibility with automated SMT placement.

Technical Context

This single-die standard recovery rectifier operates with glass-passivated junction for stable reverse leakage (<1µA @ 25°C, <250µA @ 125°C) and low forward conduction loss. Its DO-214AB (SMC) package supports high-power density layouts with matte tin-plated leads compliant to J-STD-002 solderability and JESD 201 Class 2 whisker resistance.

Thermal performance is defined by R_θJL = 8°C/W and R_θJA = 44°C/W, enabling reliable operation under sustained 15A DC load when mounted on adequate copper area. Polarity is marked by cathode band; moisture sensitivity level is J-STD-020 Level 1.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - Maximum repetitive reverse blocking voltage; defines usable input voltage range in AC/DC front-end and flyback snubber circuits.
I_F	15 A - Continuous average forward current rating; determines heatsink sizing and PCB copper requirements for steady-state conduction.
I_FSM	350 A - Non-repetitive peak surge current (8.3ms half-sine); ensures robustness against line transients and inrush events.
V_F	≤1.1 V @ 15A, 25°C - Forward voltage drop directly impacts conduction loss and thermal rise in high-current rectification stages.
R_θJL	8 °C/W - Junction-to-lead thermal resistance; enables direct thermal coupling to PCB copper or heatsink via leadframe for efficient heat extraction.
C_J	93 pF @ 1MHz, 4V - Junction capacitance affects high-frequency switching noise and EMI filter design in SMPS applications.

Pinout & Package

Package: DO-214AB (SMC) - Surface-mount plastic case with matte tin-plated leads, UL 94V-0 rated molding compound, cathode polarity indicated by band, weight ≈0.270g.

Applications

Telecom Power Rectification	Server PSU Freewheeling Diode
Use Scenario: Input rectification stage of 48V telecom DC-DC converters handling 300–1000W loads with strict efficiency targets. IC Role / Device Role / Timing Role: Standard recovery rectifier conducting during positive AC half-cycles; handles 15A continuous and transient surges up to 350A.

Equivalent & Alternatives

The following parts are listed as comparable options for similar rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1508D	V_RRM = 800V, I_F = 15A, but faster recovery (t_rr = 75ns vs. ~2µs for S15KC M6G); higher V_F (1.25V typical).	Better suited for high-frequency PFC stages; less optimal for low-loss freewheeling where standard recovery suffices.	Select STTH1508D only if t_rr reduction justifies higher conduction loss and cost premium.
ON Semi MUR1580	V_RRM = 800V, I_F = 15A, ultrafast recovery (t_rr = 60ns), V_F = 1.2V typ.; same DO-214AB package.	Preferred in resonant LLC or ZVS topologies requiring fast commutation; not required for conventional flyback or forward converters.	Choose MUR1580 only when circuit timing demands sub-100ns recovery; otherwise S15KC M6G delivers superior efficiency at lower cost.

Compared with STTH1508D and MUR1580, the S15KC M6G prioritizes low forward loss and thermal robustness over speed-making it optimal for cost-sensitive, thermally constrained 50–100kHz SMPS where standard recovery is sufficient and efficiency is critical.

FAQ

What is the maximum junction temperature rating for the S15KC M6G?

The S15KC M6G has a maximum junction temperature (T_J) of +150°C and a minimum of –55°C. This rating enables operation in demanding environments such as enclosed telecom power modules or industrial motor drive cabinets. Thermal design must ensure that actual junction temperature stays within this range under worst-case load and ambient conditions. The S15KC M6G's R_θJL = 8°C/W supports effective heat transfer to the PCB or heatsink.

Does the S15KC M6G have RoHS and halogen-free compliance?

Yes, the S15KC M6G is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability standards, and its matte tin-plated leads satisfy J-STD-002 solderability requirements. These certifications confirm suitability for environmentally regulated end equipment including EU-based telecom infrastructure and enterprise computing hardware using the S15KC M6G.

What does the "M6G" suffix indicate in S15KC M6G?

The "M6G" suffix in S15KC M6G denotes Taiwan Semiconductor's internal packaging and marking variant: "M" indicates tape-and-reel packaging (3,000 units per reel), "6" specifies green compound (halogen-free), and "G" confirms compliance with JEDEC moisture sensitivity level 1 per J-STD-020. This coding ensures correct handling, storage, and assembly of the S15KC M6G in high-volume SMT lines.

How does the S15KC M6G compare to the S15MC in terms of voltage rating?

The S15KC M6G has a V_RRM of 800V, while the S15MC is rated for 1000V. Both share identical current ratings (I_F = 15A, I_FSM = 350A), thermal specs (R_θJL = 8°C/W), and DO-214AB packaging. Choose S15KC M6G for 400–600VAC input systems with margin; select S15MC only when 700–800VAC inputs or enhanced safety margins require 1000V blocking capability.

Is the S15KC M6G suitable for use in high-humidity environments?

Yes-the S15KC M6G features a glass-passivated chip junction and J-STD-020 Level 1 moisture sensitivity, meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to reflow. Its hermetically molded DO-214AB package and conformal coating compatibility make it suitable for humid industrial or outdoor telecom enclosures where condensation or long-term exposure may occur during operation of the S15KC M6G.
