Taiwan Semiconductor Corporation S5J R7G

Overview

S5J R7G from Taiwan Semiconductor is a 5 A, 600 V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 100 A peak surge current capability, 1.15 V max forward voltage at 5 A, and 10 µA max reverse leakage at 25°C - deployed in AC/DC front-end rectification stages of compact switching power supplies.

For engineers reviewing the S5J R7G datasheet, S5J R7G pinout, S5J R7G application, or S5J R7G equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (13 °C/W junction-to-lead), reverse recovery time (1500 ns), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance for high-reliability industrial adapter designs.

Technical Context

This single-die standard recovery rectifier uses glass-passivated junction technology to achieve stable reverse blocking and low conduction loss under continuous 5 A DC forward current. Its 150 °C maximum junction temperature and 47 °C/W junction-to-ambient thermal resistance support operation in thermally constrained SMT layouts without forced airflow.

The device exhibits 60 pF junction capacitance at 4 V reverse bias and 1500 ns reverse recovery time under defined test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A), making it suitable for non-critical-frequency SMPS where EMI filtering is managed externally.

FAQ

What is the maximum junction temperature rating for the S5J R7G?

The S5J R7G has a maximum junction temperature (T_JMAX) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet F2102. This rating allows sustained operation in enclosed industrial power supplies up to 70°C ambient when using adequate PCB copper area. Derating begins above 75°C ambient per the forward current derating curve in Figure 1 of the same document. The S5J R7G must not be operated beyond this thermal limit to ensure reliability.

Does the S5J R7G meet RoHS and halogen-free requirements?

Yes, the S5J R7G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor S5A–S5M datasheet (Version F2102). The molding compound contains no brominated flame retardants or chlorine-based additives, and all lead finishes meet EU Directive 2011/65/EU. This makes the S5J R7G suitable for export to EU, Japan, and South Korea markets with strict environmental regulations.

What is the reverse recovery time (t_rr) specification for the S5J R7G?

The S5J R7G has a reverse recovery time (t_rr) of 1500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the ELECTRICAL SPECIFICATIONS table in the F2102 datasheet. This value reflects standard recovery behavior and is appropriate for line-frequency and 50–100 kHz SMPS topologies. It is not rated for high-frequency ZVS circuits where sub-100 ns recovery is required. The S5J R7G's t_rr is consistent across the full S5A–S5M family.

Is the S5J R7G compatible with lead-free reflow soldering processes?

Yes, the S5J R7G features matte tin-plated leads qualified per J-STD-002 for solderability and is rated MSL Level 1 per J-STD-020, meaning it can undergo standard Pb-free reflow profiles (peak 260°C) without baking or special handling. The device's DO-214AB package and internal construction are fully compatible with IPC-J-STD-020D-compliant thermal profiles, including ramp rates and dwell times. No preconditioning is needed before SMT placement or reflow of the S5J R7G.

What does the 'R7G' suffix indicate in the S5J R7G part number?

The 'R7G' suffix in S5J R7G denotes Taiwan Semiconductor's internal date code and packaging variant: 'R7' indicates week 7 of 2023 (or 2033), and 'G' specifies green (halogen-free) molding compound per IEC 61249-2-21. This suffix does not affect electrical specifications - all S5J devices share identical V_RRM = 600 V, I_F = 5 A, and thermal parameters regardless of R7G or other date-code variants. The S5J R7G remains functionally and dimensionally identical to S5J units with different suffixes.
