Product details
Overview
S8KC V7G from Taiwan Semiconductor is an 8A, 800V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, low forward voltage drop (max 0.985 V at 8 A), high surge capability (200 A @ 8.3 ms), and RoHS/halogen-free compliance - used in SMPS primary-side rectification and AC-DC adapters.
For engineers reviewing the S8KC V7G datasheet, S8KC V7G pinout, S8KC V7G application, or S8KC V7G equivalent, key selection criteria include repetitive peak reverse voltage (800 V), thermal resistance (RθJL = 12.5 °C/W), moisture sensitivity level (MSL 1), cathode-band polarity marking, and tape-and-reel packaging (3,000 pcs).
Technical Context
This single-die standard recovery rectifier operates with a maximum junction temperature of 150 °C and supports continuous forward current of 8 A at lead temperature ≤ 100 °C. Its 800 V VRRM rating enables use in universal-input offline power supplies up to 265 VAC.
Thermal performance is defined by RθJL = 12.5 °C/W and RθJA = 44.0 °C/W under standard PCB mounting. Reverse leakage remains ≤10 µA at 25 °C and ≤250 µA at 125 °C under rated reverse voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - supports 265 VAC input with ≥2× safety margin in bridge or single-diode rectifier stages |
| IF | 8 A continuous - delivers full-rated output power in compact 1U adapters and LED drivers |
| IFSM (8.3 ms) | 200 A - withstands cold-start surges and line transients without failure |
| VF (8 A, 25 °C) | ≤0.985 V - reduces conduction loss and improves efficiency in high-current paths |
| RθJL | 12.5 °C/W - enables direct thermal coupling to copper pour for reliable 8 A operation without heatsink |
| Junction capacitance | 48 pF @ 1 MHz, 4 V - limits high-frequency switching noise in quasi-resonant converters |
Pinout & Package
Package: DO-214AB (SMC), molded plastic case meeting UL 94V-0; matte tin-plated leads; cathode indicated by band; MSL Level 1; weight ≈ 0.270 g.

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R06D | 600 V VRRM, 8 A, TO-220AC package, faster recovery (~65 ns) | Lower voltage rating; through-hole mounting; suited for lower-cost, non-automated assembly | Select when board space permits TO-220 and system peak reverse stress < 600 V |
| VS-8EWH06FN-M3/45 | 600 V VRRM, 8 A, DO-214AB, ultra-low VF (0.82 V typ) | Same package but lower voltage rating; optimized for efficiency-critical low-VRRM designs | Choose when VRRM margin can be reduced and forward loss reduction is prioritized over surge robustness |
Compared with STTH8R06D and VS-8EWH06FN-M3/45, the S8KC V7G uniquely delivers 800 V standoff in surface-mount DO-214AB while maintaining MSL 1 handling, making it optimal for automated, universal-input, high-reliability adapter and SMPS designs where voltage margin and manufacturability are critical.

FAQ
What is the peak repetitive reverse voltage rating of the S8KC V7G?
The S8KC V7G has a peak repetitive reverse voltage (VRRM) rating of 800 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version G2210). It ensures safe operation under worst-case line transients in 230 VAC systems and provides sufficient margin for 265 VAC universal-input designs. The S8KC V7G is part of the S8GC–S8MC series where 'K' explicitly denotes the 800 V grade.
Does the S8KC V7G have a halogen-free and RoHS-compliant construction?
Yes, the S8KC V7G is both RoHS compliant and halogen-free per IEC 61249-2-21. This is explicitly stated in the FEATURES section of the Taiwan Semiconductor documentation. The device uses green molding compound and meets JEDEC MSL Level 1 requirements, supporting lead-free reflow processes without moisture-related defects. These attributes are integral to the S8KC V7G's qualification for modern consumer and industrial electronics.
What is the forward voltage drop of the S8KC V7G at rated current?
The S8KC V7G exhibits a maximum forward voltage drop (VF) of 0.985 V at 8 A and 25 °C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At elevated junction temperatures (e.g., 125 °C), VF decreases slightly, but the 0.985 V limit remains the design reference for worst-case conduction loss calculation in the S8KC V7G.
Is the S8KC V7G supplied in tape-and-reel packaging?
Yes, the S8KC V7G is supplied in tape-and-reel packaging with 3,000 units per reel, as documented in the Ordering Information section. This format is standard for DO-214AB (SMC) devices and supports high-speed automated placement in SMT lines. The reel packaging complies with EIA-481 standards and includes MSL 1 handling instructions consistent with the device's moisture sensitivity classification.
What thermal resistance values apply to the S8KC V7G in standard mounting?
The S8KC V7G has a junction-to-lead thermal resistance (RθJL) of 12.5 °C/W and a junction-to-ambient resistance (RθJA) of 44.0 °C/W under standard test conditions (JEDEC JESD51-3, 1 in² 2 oz Cu). These values assume the device is soldered to a minimum 1 in² copper pad on the primary side of a FR-4 PCB. RθJL is the more relevant metric for the S8KC V7G in typical power supply layouts, as heat is primarily conducted through the leads into internal copper planes.
