Product details
Overview
RS2GA from Taiwan Semiconductor is a 1.5A, 400V fast recovery surface-mount rectifier diode in DO-214AC (SMA) package, featuring 150 ns reverse recovery time, 1.3 V max forward voltage at 1.5 A, and 5 µA max reverse leakage at 25°C. It serves as a primary output rectifier in DC-DC converters and snubber circuits requiring high efficiency and thermal robustness.
For engineers reviewing the RS2GA datasheet, RS2GA pinout, RS2GA application, or RS2GA equivalent, key selection criteria include its 400 V repetitive peak reverse voltage, 50 A surge rating, 175°C maximum junction temperature, DO-214AC mechanical compatibility, and fast switching performance for high-frequency power conversion designs.
Technical Context
The RS2GA operates as a single-die, unidirectional silicon rectifier with glass-passivated junction for enhanced reliability and moisture resistance (J-STD-020 Level 1). Its 150 ns trr enables efficient operation in 100–500 kHz switching topologies.
Thermal design is supported by RθJL = 18°C/W and RθJA = 55°C/W, enabling 1.5 A continuous conduction in standard PCB layouts without forced airflow. The cathode band polarity marking and matte tin-plated leads ensure automated assembly compatibility per J-STD-002.

| IR (max) | 5 µA @ 400 V, 25°C - Low leakage preserves efficiency in high-impedance hold-up or sensing paths |
| RθJL | 18 °C/W - Junction-to-lead thermal resistance; enables direct heat transfer to copper pour or heatsink via cathode pad |
| Package | DO-214AC (SMA) - Industry-standard surface-mount outline with 4.06 mm body width and 2.29 mm height; compatible with JEDEC-compliant pick-and-place |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06U (STMicroelectronics) | Same 1.5 A / 600 V rating; 75 ns trr; TO-277A package (lower RθJA) | Higher speed suits >1 MHz resonant converters; requires different footprint and thermal pad layout | Select when faster recovery or lower thermal resistance is required and board redesign is feasible |
| ES1D (ON Semiconductor) | 1 A / 200 V; 35 ns trr; same DO-214AC package; lower IF and VRRM | Limited to ≤200 V, ≤1 A applications; unsuitable for 400 V bus or 1.5 A loads | Acceptable only in derated, lower-voltage designs where size and assembly compatibility are prioritized over rating |
Compared with STTH1L06U, RS2GA offers higher voltage margin (400 V vs. 600 V) but slower recovery; versus ES1D, it delivers 50% higher current and doubles VRRM, making it suitable for 400 V industrial power supplies where cost and footprint match are critical.

FAQ
What is the maximum junction temperature rating for RS2GA?
The RS2GA has a maximum junction temperature (TJ) rating of +175°C, allowing reliable operation in high-ambient environments such as enclosed LED drivers or industrial motor control enclosures. This rating is validated per TSC's absolute maximum ratings table and supports extended lifetime under thermal stress when mounted on adequate copper area.
Does RS2GA have a RoHS-compliant and halogen-free construction?
Yes, RS2GA is both RoHS compliant and halogen-free, as explicitly stated in the official Taiwan Semiconductor datasheet. These attributes meet EU Directive 2011/65/EU and IPC-4101D requirements, making RS2GA suitable for environmentally regulated end equipment including consumer electronics and industrial automation systems.
What is the reverse recovery time (trr) specification for RS2GA?
The RS2GA has a reverse recovery time (trr) of 150 ns, measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the Electrical Specifications table of the RS2AA–RS2MA datasheet and reflects its suitability for high-frequency switching applications up to 500 kHz.
Is RS2GA pin-compatible with other devices in the RS2x family?
Yes, all RS2x devices-including RS2GA-share identical DO-214AC (SMA) package dimensions, lead spacing, and polarity marking (cathode band), enabling drop-in replacement within the same voltage grade group. However, VRRM, trr, and thermal performance differ across variants, so electrical validation is required before substitution.
What is the forward voltage drop of RS2GA at rated current?
The RS2GA exhibits a maximum forward voltage (VF) of 1.3 V at IF = 1.5 A and TJ = 25°C, as specified in the Electrical Specifications table. This value directly determines conduction loss and thermal load in the rectification stage, and remains stable across the −55°C to +175°C operating junction temperature range.
