Product details

Overview

RS2J R5G from Taiwan Semiconductor is a 2 A, 600 V fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 250 ns reverse recovery time, 1.3 V max forward voltage at 2 A, and 5 µA max reverse leakage at 25°C - deployed in AC/DC front-end stages of compact switching power supplies.

For engineers reviewing the RS2J R5G datasheet, RS2J R5G pinout, RS2J R5G application, or RS2J R5G equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (R_θJA = 55 °C/W), junction temperature range (–55 to +175 °C), and JEDEC-compliant SMB packaging for automated SMT assembly.

Technical Context

This discrete rectifier uses a glass-passivated silicon die optimized for fast switching in high-frequency SMPS topologies. Its single-die configuration supports unidirectional conduction with cathode-band polarity marking and meets JESD201 Class 2 whisker resistance.

Thermally, it delivers R_θJL = 18 °C/W to lead and operates up to 175 °C junction temperature. The 50 pF junction capacitance at 4 V reverse bias enables stable performance in 100 kHz–1 MHz converter designs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast recovery rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R06U	Same 600 V V_RRM, 2 A I_F, but TO-220AC package; t_rr = 200 ns; VF = 1.7 V typ	Requires through-hole mounting and larger heatsink; higher V_F increases conduction loss	Select when board-level thermal mass supports TO-220 and lower t_rr is prioritized over SMT compatibility
ON Semi MUR260	Same DO-214AA package, 600 V, 2 A, but t_rr = 35 ns; V_F = 1.75 V max; R_θJA = 70 °C/W	Superior speed but higher forward drop and worse thermal resistance than RS2J R5G	Select when ultra-fast recovery dominates over thermal efficiency and conduction loss in high-frequency designs

Compared with STTH2R06U and MUR260, RS2J R5G balances speed (250 ns), low V_F (1.3 V), and thermal performance (55 °C/W) in an SMT-optimized SMB package - making it optimal for cost-sensitive, space-constrained 60–300 kHz SMPS where reliability and manufacturability are critical.

FAQ

What is the maximum junction temperature rating for RS2J R5G?

The RS2J R5G has a maximum junction temperature (T_J) of +175 °C and a minimum of –55 °C. This wide operating range allows deployment in harsh environments such as industrial control cabinets or enclosed LED luminaires. Derating begins above 25 °C ambient per the forward current derating curve in the RS2A–RS2M datasheet. RS2J R5G maintains specified electrical parameters within this full range.

Does RS2J R5G support lead-free reflow soldering?

Yes, RS2J R5G features matte tin-plated leads compliant with J-STD-002 solderability standards and rated for lead-free reflow profiles (peak temperature up to 260 °C). Its moisture sensitivity level is J-STD-020 Level 1, meaning no dry-pack or baking is required before SMT assembly - simplifying manufacturing for RS2J R5G integration into high-volume production lines.

What is the reverse recovery time (t_rr) specification for RS2J R5G?

The RS2J R5G has a maximum reverse recovery time (t_rr) of 250 ns under test conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is confirmed in the Electrical Specifications table of the RS2A–RS2M datasheet (Version L2304, Page 2). RS2J R5G's 250 ns t_rr supports efficient operation in 100–500 kHz switching power supplies.

Is RS2J R5G halogen-free and RoHS compliant?

Yes, RS2J R5G is both halogen-free and RoHS compliant, as explicitly stated in the FEATURES section of the official Taiwan Semiconductor RS2A–RS2M datasheet. The molding compound contains no brominated or chlorinated flame retardants, and all homogeneous materials meet EU Directive 2011/65/EU requirements. RS2J R5G documentation confirms full compliance without exemptions.

What does the 'R5G' suffix indicate in RS2J R5G?

The 'R5G' suffix in RS2J R5G is Taiwan Semiconductor's internal tape-and-reel packaging code indicating 3,000 units per reel in DO-214AA (SMB) package. It does not denote electrical variation - all RS2J devices share identical V_RRM = 600 V, I_F = 2 A, and t_rr = 250 ns specifications regardless of reel code. RS2J R5G is functionally and electrically identical to RS2J in other packing formats.
