Product details

Overview

RS2J-T 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, 1.13 V forward voltage at 2 A / 25°C, and 5 µA max reverse leakage at 25°C. It serves as a primary output rectifier in offline AC/DC power supplies and DC-DC converters requiring high efficiency and compact layout.

For engineers reviewing the RS2J-T datasheet, RS2J-T pinout, RS2J-T application, or RS2J-T equivalent, key selection criteria include its 600 V V_RRM, thermal resistance of 20 °C/W (junction-to-lead), moisture sensitivity level 1 compliance, and suitability for automated SMT assembly in industrial and consumer power systems.

Technical Context

The RS2J-T employs a glass-passivated silicon junction optimized for fast switching with controlled soft recovery characteristics. Its 250 ns trr enables reduced switching losses in 50–500 kHz SMPS topologies while maintaining low conduction loss via low VF and high surge capability (50 A I_FSM at 8.3 ms).

Thermally, it delivers R_θJL = 20 °C/W on standard PCB mounting (10 mm × 10 mm Cu pad), supporting continuous 2 A operation up to +125°C ambient when derated per curve Fig.1. Polarity is marked by cathode band; leads are matte tin-plated per J-STD-002.

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, but 175 ns t_rr; VF = 1.15 V @ 2 A; DO-214AA package	Better recovery speed suits higher-frequency (>300 kHz) designs; slightly higher VF increases conduction loss	Prefer STTH2R06U where switching loss dominates thermal budget
ES2J	Same 600 V V_RRM, 250 ns t_rr, but VF = 1.7 V @ 2 A; same DO-214AA package	Higher VF raises conduction loss by ~1.3 W at full load, requiring larger copper area or derating	Choose RS2J-T over ES2J where efficiency >85% is required at 2 A output

Compared with STTH2R06U and ES2J, the RS2J-T balances recovery speed and forward loss more effectively for 100–250 kHz industrial SMPS, offering lower thermal resistance and tighter VF distribution across temperature.

FAQ

What is the maximum repetitive peak reverse voltage rating for RS2J-T?

The RS2J-T has a maximum repetitive peak reverse voltage (V_RRM) of 600 V, verified per Taiwan Semiconductor's C2102 datasheet. This rating ensures reliable blocking capability in 400 V DC bus applications and 230 VAC line-fed flyback converters with sufficient safety margin. The RS2J-T must not be operated beyond this voltage under any condition, including transient spikes.

Does RS2J-T support lead-free reflow soldering?

Yes, RS2J-T supports lead-free reflow soldering per J-STD-002. Its matte tin-plated leads are qualified for peak temperatures up to 260°C with 10-second duration. The device meets moisture sensitivity level 1 (MSL-1), eliminating pre-bake requirements and enabling direct placement into standard SMT lines without process modification.

What is the reverse recovery time of RS2J-T and how is it measured?

The RS2J-T has a reverse recovery time (t_rr) of 250 ns maximum, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A per the C2102 datasheet. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss in high-frequency SMPS designs.

Is RS2J-T halogen-free and RoHS compliant?

Yes, RS2J-T is both RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all homogeneous materials meet EU Directive 2011/65/EU limits for lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE.

What thermal resistance values apply to RS2J-T in standard PCB mounting?

When mounted on a 10 mm × 10 mm copper pad test board, RS2J-T exhibits R_θJL = 20 °C/W (junction-to-lead), R_θJC = 26 °C/W (junction-to-case), and R_θJA = 78 °C/W (junction-to-ambient). These values enable accurate thermal modeling for 2 A continuous operation up to +70°C ambient without forced air or heatsinking.
