Product details

Overview

RS2G-T from Taiwan Semiconductor is a 2A, 400V fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 150 ns reverse recovery time, 1.11 V forward voltage at 2A/25°C, and 50 A surge current capability. It serves as a primary AC/DC input rectifier in compact switching power supplies.

For engineers reviewing the RS2G-T datasheet, RS2G-T pinout, RS2G-T application, or RS2G-T equivalent, key selection criteria include V_RRM = 400 V, t_rr ≤ 150 ns, I_F = 2 A continuous, thermal resistance R_θJA = 78 °C/W, and DO-214AA mechanical compatibility with automated SMT assembly.

Technical Context

The RS2G-T employs a glass-passivated silicon junction optimized for fast recovery (t_rr = 150 ns max) and low conduction loss (V_F = 1.11 V @ 2A, 25°C). Its single-die configuration supports unidirectional current flow with cathode-band polarity marking.

Designed for high-frequency switching environments, it delivers stable performance across –55°C to +150°C junction temperature range and maintains low reverse leakage (I_R ≤ 5 µA @ 25°C, rated V_R). Thermal design relies on R_θJL = 20 °C/W and PCB-mounted R_θJA = 78 °C/W.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input voltage derating margin in bridge or single-phase rectifiers.
I_F	2 A - Continuous forward current rating; determines minimum trace width and heatsinking for sustained operation.
t_rr	150 ns - Reverse recovery time; enables efficient operation up to ~500 kHz switching frequencies without excessive switching loss.
V_F @ 2A, 25°C	1.11 V - Forward voltage drop; directly impacts conduction loss (P_cond ≈ 2.22 W) and thermal rise in DC-DC front-end stages.
I_FSM	50 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush current handling during cold-start of offline SMPS.
R_θJA	78 °C/W - Junction-to-ambient thermal resistance on 10 mm × 10 mm Cu pad; used to calculate max ambient temperature for 150°C T_J limit.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R04	V_RRM = 400 V, t_rr = 35 ns (faster), I_F = 2 A, same DO-214AA package	Lower switching loss in >1 MHz designs; higher cost and tighter V_F tolerance	Preferred when ultra-low t_rr is required and budget allows premium performance.
ES2G	V_RRM = 400 V, t_rr = 35 ns, I_F = 2 A, same DO-214AA, but higher V_F (1.25 V @ 2A)	Higher conduction loss; slightly lower thermal resistance (R_θJA = 70 °C/W)	Suitable where faster recovery is critical and 0.14 V higher V_F is acceptable for thermal budget.

Compared with STTH2R04 and ES2G, the RS2G-T offers balanced trade-offs: moderate t_rr (150 ns) for cost-sensitive 100–500 kHz designs, proven reliability in mass-produced adapters, and lowest V_F among the three at 2A/25°C (1.11 V).

FAQ

What is the maximum junction temperature rating for RS2G-T?

The RS2G-T has a maximum junction temperature (T_J) rating of +150°C, with operational range from –55°C to +150°C. This allows reliable use in enclosed power supplies and industrial environments where ambient temperatures exceed 70°C, provided thermal design respects R_θJA = 78 °C/W on standard PCB mounting. The RS2G-T must not exceed this limit to maintain specified electrical parameters and long-term reliability.

Does RS2G-T have a halogen-free construction?

Yes, the RS2G-T uses halogen-free molding compound compliant with IEC 61249-2-21. This eliminates brominated flame retardants and supports environmental compliance for export to EU, Japan, and other regulated markets. The halogen-free status is verified per TSC's material declarations and applies to the entire RS2x-T series, including RS2G-T.

What is the reverse recovery time (t_rr) specification for RS2G-T?

The RS2G-T has a maximum reverse recovery time (t_rr) of 150 ns, measured at I_F = 0.5 A, I_R = 1.0 A, and I_RR = 0.25 A. This value is confirmed in the official TSC datasheet Version C2102 and applies specifically to RS2G-T-not extrapolated from adjacent variants. The 150 ns t_rr enables efficient operation in switching power supplies operating up to 500 kHz.

Is RS2G-T pin-compatible with RS2D-T or RS2J-T?

No, RS2G-T is not pin-compatible in the functional sense with RS2D-T or RS2J-T-though all share the identical DO-214AA (SMB) package and two-terminal anode/cathode configuration. Their V_RRM ratings differ (200 V, 400 V, 600 V), so substituting RS2G-T for RS2D-T risks overvoltage failure, and vice versa may cause premature breakdown. Physical fit does not imply electrical interchangeability.

What packaging format is available for RS2G-T?

The RS2G-T is supplied in tape-and-reel packaging, with 3,000 units per reel, conforming to EIA-481 standards. This format supports automated SMT placement and is compatible with standard pick-and-place equipment. No alternate packaging (e.g., bulk, ammo pack) is offered for RS2G-T per TSC's ordering information in Version C2102.
