Product details
Overview
S5K R7G from Taiwan Semiconductor is a 5 A, 800 V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, low forward voltage drop (≤1.15 V at 5 A), and high surge capability (100 A, 8.3 ms). It serves as the main output rectifier in offline AC/DC power supplies for industrial adapters and LED drivers.
For engineers reviewing the S5K R7G datasheet, S5K R7G pinout, S5K R7G application, or S5K R7G equivalent, key selection criteria include repetitive peak reverse voltage (800 V), thermal resistance (RθJL = 13 °C/W), reverse recovery time (1500 ns), and moisture sensitivity level (MSL 1).
Technical Context
This device is a single-die, standard recovery silicon rectifier optimized for high-efficiency switching-mode power supplies operating up to 100 kHz. Its 150 °C maximum junction temperature and 13 °C/W junction-to-lead thermal resistance support continuous conduction mode operation under thermally constrained PCB layouts.
The 1500 ns reverse recovery time and 60 pF junction capacitance reflect its design for moderate-frequency rectification where fast recovery is not required but robust surge handling is critical. It exhibits ≤10 µA reverse leakage at 25 °C and ≤250 µA at 125 °C under rated reverse voltage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06S | 600 V VRRM, 120 ns trr, TO-277 package | Lower voltage rating; faster recovery but lower surge tolerance (80 A) | Prefer for <600 V systems requiring reduced switching loss |
| ON Semi MUR580 | 800 V VRRM, 75 ns trr, DO-214AB, 50 A IFSM | Ultrafast recovery; lower surge rating limits use in high-inrush adapters | Choose when EMI reduction is critical and surge events are controlled |
Compared with STTH5L06S and MUR580, the S5K R7G delivers superior surge robustness and thermal performance at 800 V, making it optimal for cost-sensitive, high-reliability industrial power supplies where moderate switching frequency and ruggedness outweigh ultrafast recovery needs.

FAQ
What is the maximum junction temperature rating for the S5K R7G?
The S5K R7G has a maximum junction temperature (TJMAX) of +150 °C, enabling operation in high-ambient environments such as enclosed LED drivers or industrial control cabinets. This rating is validated per JEDEC test conditions and supports derated continuous current up to 5 A at case temperatures ≤115 °C. Thermal design must account for RθJL = 13 °C/W to ensure safe operation within this limit.
Does the S5K R7G meet RoHS and halogen-free requirements?
Yes, the S5K R7G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants, and the matte tin-plated leads satisfy J-STD-002 solderability standards. These certifications are confirmed in Taiwan Semiconductor's official product change notices and material declarations for the S5x family.
What is the reverse recovery time (trr) specification for the S5K R7G?
The S5K R7G has a typical reverse recovery time (trr) of 1500 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value reflects its standard recovery behavior-suitable for flyback and forward converters operating below 100 kHz-but not recommended for high-frequency synchronous rectification. The datasheet specifies no maximum trr, only typical.
Is the S5K R7G suitable for automated SMT assembly?
Yes, the S5K R7G is qualified for automated placement and reflow soldering. It carries MSL Level 1 per J-STD-020, requires no pre-bake, and features matte tin-plated leads compatible with standard Pb-free reflow profiles. The DO-214AB (SMC) package geometry and 0.210 g weight ensure stable pick-and-place accuracy and high first-pass yield in high-volume production.
How does the S5K R7G compare to the S5M R7G in terms of voltage rating?
The S5K R7G is rated for 800 V repetitive peak reverse voltage (VRRM), while the S5M R7G is rated for 1000 V. Both share identical package (DO-214AB), current rating (5 A), thermal specs (RθJL = 13 °C/W), and construction. Select S5K R7G where 800 V provides sufficient margin over system peak voltage-typically reducing cost and improving availability versus the 1000 V S5M R7G.
