Taiwan Semiconductor Corporation S8KC R7G

Overview

S8KC R7G 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), and high surge capability (200 A @ 8.3 ms). It is used in SMPS primary-side rectification where high-voltage blocking and thermal robustness are required.

For engineers reviewing the S8KC R7G datasheet, S8KC R7G pinout, S8KC R7G application, or S8KC R7G equivalent, key selection criteria include repetitive peak reverse voltage (800 V), forward current rating (8 A), junction-to-lead thermal resistance (12.5 °C/W), and moisture sensitivity level (J-STD-020 Level 1).

Technical Context

This single-die standard recovery rectifier operates with a maximum junction temperature of 150 °C and supports continuous forward conduction up to 8 A at 25 °C ambient. Its 800 V V_RRM rating enables use in universal-input offline power supplies and DC-DC converters requiring medium-voltage isolation.

Thermal performance is defined by R_θJL = 12.5 °C/W and R_θJA = 44.0 °C/W, indicating efficient heat transfer to PCB copper and moderate self-heating under full load. Reverse leakage remains ≤10 µA at 25 °C and ≤250 µA at 125 °C under rated VR.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for the S8KC R7G?

The S8KC R7G has a maximum repetitive peak reverse voltage (V_RRM) of 800 V, as specified in the absolute maximum ratings table. This value is fixed per the "K" designation in the S8xC series and is verified across production lots per Taiwan Semiconductor's G2210 datasheet revision. The S8KC R7G must not be subjected to reverse voltages exceeding this rating under normal operating conditions.

Is the S8KC R7G suitable for automated SMT assembly?

Yes, the S8KC R7G is optimized for automated placement: it uses DO-214AB (SMC) packaging with matte tin-plated leads compliant with J-STD-002 solderability requirements, and carries J-STD-020 moisture sensitivity level 1-eliminating pre-bake steps. The S8KC R7G is supplied in 3,000-piece tape-and-reel format compatible with standard pick-and-place equipment.

What is the forward voltage drop (V_F) of the S8KC R7G at rated current?

The S8KC R7G exhibits a maximum forward voltage drop of 0.985 V at 8 A forward current and 25 °C junction temperature, per the electrical specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss for thermal design. The S8KC R7G maintains this V_F performance across its full operating temperature range.

Does the S8KC R7G meet RoHS and halogen-free requirements?

Yes, the S8KC R7G is RoHS compliant and halogen-free per IEC 61249-2-21. These compliance statements are explicitly confirmed in the features section of the official Taiwan Semiconductor datasheet (Version G2210). The S8KC R7G contains no brominated flame retardants or chlorine-based compounds above threshold limits, and all plating and molding materials are certified accordingly.

What is the thermal resistance from junction to lead (R_θJL) for the S8KC R7G?

The junction-to-lead thermal resistance (R_θJL) of the S8KC R7G is 12.5 °C/W, as published in the thermal performance section of the datasheet. This parameter reflects the dominant thermal path from die to soldered lead and is critical for estimating temperature rise when mounting directly to copper pour. The S8KC R7G achieves this value using standard DO-214AB construction with no thermal enhancements required.
