Product details
Overview
S5K V7G from Taiwan Semiconductor is a 5A, 800V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, low forward voltage drop (max 1.15V at 5A), and high surge capability (100A IFSM). It serves as a primary AC/DC conversion device in offline switch-mode power supplies for industrial adapters and LED drivers.
For engineers reviewing the S5K V7G datasheet, S5K V7G pinout, S5K V7G application, or S5K V7G equivalent, key selection criteria include repetitive peak reverse voltage (800V), thermal resistance (13°C/W junction-to-lead), reverse recovery time (1500ns), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
This single-die standard recovery rectifier operates with a maximum junction temperature of 150°C and exhibits a typical junction capacitance of 60pF at 1MHz and 4V reverse bias. Its 1500ns reverse recovery time reflects moderate switching speed suitable for 50–100kHz SMPS topologies.
The device uses matte tin-plated leads compliant with J-STD-002 solderability and meets JESD 201 Class 2 whisker resistance. Polarity is marked by a cathode band on the DO-214AB molded case, which carries UL 94V-0 flammability rating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06 from STMicroelectronics | 600V VRRM, 5A IF, 100ns trr, TO-220AC package | Higher switching speed but lower voltage rating; through-hole mounting required | Select when faster recovery is needed and board space allows through-hole layout |
| VS-5EWH06FN-M3 from Vishay | 600V VRRM, 5A IF, 120ns trr, DO-214AB package, AEC-Q101 qualified | Automotive-grade qualification; not rated for 800V systems | Prefer for automotive lighting where qualification matters more than voltage headroom |
Compared with STTH5L06 and VS-5EWH06FN-M3, the S5K V7G delivers higher voltage blocking (800V vs. 600V) in the same surface-mount DO-214AB footprint, making it optimal for universal-input industrial power supplies where safety margin and SMT scalability are prioritized over ultrafast recovery.

FAQ
What is the maximum junction temperature rating for the S5K V7G?
The S5K V7G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official TSC datasheet F2102. This allows reliable operation in enclosed industrial enclosures with limited airflow. Derating curves show usable average forward current drops to ~3.5A at 125°C lead temperature. The S5K V7G must be mounted on sufficient copper area to maintain this limit under full load.
Does the S5K V7G meet RoHS and halogen-free requirements?
Yes, the S5K V7G is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. These compliance statements appear in the "Features" section of the TSC S5A–S5M datasheet (Version F2102). The device uses bromine-free flame retardants in its DO-214AB molding compound and contains no chlorine, bromine, fluorine, iodine, or astatine above threshold limits.
What is the reverse recovery time (trr) specification for the S5K V7G?
The S5K V7G has a reverse recovery time (trr) of 1500 ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A conditions per the electrical specifications table in the TSC datasheet. This value confirms its classification as a standard recovery rectifier-not optimized for high-frequency (>200kHz) topologies. The S5K V7G is best suited for 50–100kHz flyback and forward converters where EMI filtering and voltage margin outweigh speed demands.
Is the S5K V7G suitable for automated SMT assembly?
Yes, the S5K V7G is explicitly designed for automated placement, as stated in its features list. Its DO-214AB (SMC) package has J-STD-002 compliant matte tin-plated leads and moisture sensitivity level 1 (per J-STD-020), eliminating pre-bake requirements. The S5K V7G's standardized tape-and-reel packaging (3,000 units per reel) supports high-speed pick-and-place machines without lead deformation or solderability risk.
What does the "V7G" suffix indicate in S5K V7G?
The "V7G" suffix in S5K V7G denotes Taiwan Semiconductor's internal date code and environmental grade: "V7" corresponds to week 7 of 2025, and "G" indicates green (halogen-free) compound per IEC 61249-2-21. This coding follows TSC's standard ordering nomenclature shown in the "Ordering Information" section of the S5A–S5M datasheet (F2102), where "S5K" defines the 800V variant and "V7G" specifies manufacturing lot and material compliance.
