Product details

Overview

RS2GA-T from Taiwan Semiconductor is a 2A, 400V fast recovery surface-mount rectifier in DO-214AC (SMA) 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 RS2GA-T datasheet, RS2GA-T pinout, RS2GA-T application, or RS2GA-T equivalent, key selection criteria include V_RRM = 400 V, I_F = 2 A continuous, t_rr ≤ 150 ns, thermal resistance R_θJL = 14 °C/W, and DO-214AC mechanical compatibility with automated SMT assembly.

Technical Context

The RS2GA-T employs a glass-passivated silicon junction optimized for fast recovery (t_rr ≤ 150 ns) and low conduction loss, with forward voltage specified at both 25°C and 125°C to support thermal design across operating ranges. Its single-die configuration and cathode-band polarity marking align with industry-standard SMA layout practices.

Thermal performance is characterized with R_θJL = 14 °C/W and R_θJA = 86 °C/W on a 5 mm × 5 mm copper pad, enabling accurate junction temperature estimation in real PCB environments. Reverse leakage remains ≤5 µA at 25°C and ≤100 µA at 125°C under rated V_RRM.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input voltage headroom in bridge or single-diode rectification.
I_F	2 A - Continuous forward current rating; determines minimum trace width and heatsinking for steady-state operation.
t_rr	≤150 ns - Reverse recovery time; critical for minimizing switching losses in 50–500 kHz SMPS topologies.
V_F @ 2A, 25°C	1.11 V - Forward voltage drop; directly impacts conduction loss (P_cond ≈ 2.22 W) and thermal rise at full load.
R_θJL	14 °C/W - Junction-to-lead thermal resistance; enables direct thermal coupling to PCB copper for passive cooling without external heatsink.
I_FSM	50 A - Non-repetitive surge current (8.3 ms); supports inrush current handling during cold-start of DC/DC converters.

Pinout & Package

Package: DO-214AC (SMA), surface-mount, single-anode/single-cathode configuration with cathode band marking. Weight: 0.060 g. Moisture sensitivity level: J-STD-020 Level 1.

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, I_F = 2 A, t_rr = 35 ns, DO-214AC, but higher cost and tighter V_F tolerance (1.05 V typ @ 2A).	Better suited for ultra-low-noise or >300 kHz designs where trr < 50 ns is required.	Select STTH2R04 only if system-level EMI testing shows benefit from faster recovery; RS2GA-T remains optimal for cost-sensitive 65–130 kHz applications.
ES2D	V_RRM = 200 V, I_F = 2 A, t_rr = 35 ns, same DO-214AC package, lower V_F (0.95 V @ 2A), but insufficient for 264 VAC input.	Limited to low-input-voltage DC/DC or secondary-side use; not suitable for universal AC input.	ES2D is viable only in fixed 12–48 VDC input systems; RS2GA-T is mandatory for universal AC mains compatibility.

Compared with STTH2R04 and ES2D, the RS2GA-T delivers balanced performance for mainstream 400 V-rated applications-offering sufficient speed (150 ns), proven thermal robustness (R_θJL = 14 °C/W), and cost-effective DO-214AC manufacturability without over-specifying for typical 65–130 kHz power conversion.

FAQ

What is the maximum junction temperature rating for RS2GA-T?

The RS2GA-T has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed LED drivers or industrial power supplies. Derating curves confirm usable current capacity down to 1.2 A at 125°C ambient when mounted on a 5 mm × 5 mm Cu pad. The RS2GA-T must be operated within this limit to ensure long-term reliability and avoid thermal runaway.

Does RS2GA-T have a defined moisture sensitivity level (MSL)?

Yes, the RS2GA-T is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and requires no baking prior to reflow soldering. This simplifies SMT line integration and eliminates moisture-related popcorning risk during standard lead-free reflow profiles. The RS2GA-T's matte tin-plated leads also comply with J-STD-002 for solderability assurance.

What is the reverse recovery time (t_rr) specification for RS2GA-T?

The RS2GA-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 Electrical Specifications table and applies across the full operating temperature range. The RS2GA-T's t_rr enables efficient operation in switching power supplies up to 150 kHz without excessive switching loss or EMI generation.

Is RS2GA-T RoHS and halogen-free compliant?

Yes, the RS2GA-T is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and all materials are documented in TSC's substance declaration. This compliance ensures suitability for export to EU, China, and other regulated markets. The RS2GA-T's green compound marking further identifies its halogen-free status on-device.

What is the forward voltage (V_F) of RS2GA-T at 2A and 125°C?

The RS2GA-T exhibits a typical forward voltage of 0.98 V and a maximum of 1.12 V at I_F = 2 A and T_J = 125°C. This reduced V_F versus room temperature (1.11 V max) reflects positive temperature coefficient behavior, improving thermal stability in high-power operation. Designers should use the 1.12 V max value for worst-case loss calculation in the RS2GA-T's thermal model.
