Product details
Overview
RS2D R5G from Taiwan Semiconductor is a 2A, 200V fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 250ns reverse recovery time, 1.3V max forward voltage at 2A, and 5µA max reverse leakage at 25°C. It serves as primary-side AC/DC rectification in compact switching power supplies.
For engineers reviewing the RS2D R5G datasheet, RS2D R5G pinout, RS2D R5G application, or RS2D R5G equivalent, key selection criteria include VRRM = 200V, IF = 2A, trr = 250ns, thermal resistance RθJA = 55°C/W, and SMB package compatibility with automated SMT assembly.
Technical Context
This discrete diode operates as a unidirectional current switch with fast recovery optimized for high-frequency switching converters. Its glass-passivated junction ensures stable performance across -55°C to +175°C junction temperature range and supports surge current up to 50A (8.3ms half-sine).
The device uses a single-die configuration in DO-214AA (SMB) outline, with cathode polarity marked by a band, matte tin-plated leads compliant with J-STD-002 solderability, and moisture sensitivity level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage the diode blocks without breakdown in SMPS primary rectification |
| IF | 2 A - Continuous average forward current rating at 75°C lead temperature, defining steady-state power handling |
| trr | 250 ns - Reverse recovery time measured at IF = 0.5A, IR = 1.0A, Irr = 0.25A; critical for minimizing switching losses above 50 kHz |
| VF (max) | 1.3 V - Maximum forward voltage drop at 2A and 25°C; directly impacts conduction loss and thermal design |
| RθJA | 55 °C/W - Junction-to-ambient thermal resistance on standard FR-4 PCB; determines required copper area for 175°C max TJ |
| IFSM | 50 A - Non-repetitive surge current capability (8.3ms half-sine); enables robustness against line transients and startup surges |

IC Role / Device Role / Timing Role: Output rectifier in isolated forward or half-bridge converters delivering regulated DC to PLC I/O stages. Use Value: RθJA = 55°C/W allows operation at full 2A load with ≤25°C temperature rise on 1-in² 2-oz copper pad. | Use Scenario: Auxiliary 5V/3.3V supply in USB-C PD controllers where space-constrained layout demands SMB footprint. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement in low-power quasi-resonant flyback 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 |
|---|---|---|---|
| STTH2R02 | VRRM = 200V, trr = 35ns (faster), VF = 1.15V (lower), but RθJA = 70°C/W (worse thermal) | Better for >1 MHz operation; less suitable for high-ambient industrial use due to higher thermal resistance | Choose STTH2R02 only if switching frequency exceeds 300 kHz and board-level cooling is enhanced |
| SB220 | VRRM = 200V, trr = 500ns (slower), VF = 0.9V (lower), IF = 2A, same SMB package | Optimized for low-VF in low-frequency (<50 kHz) applications; higher recovery loss limits high-frequency use | Select SB220 when priority is minimal conduction loss at 25°C and switching frequency remains below 30 kHz |
Compared with STTH2R02 and SB220, RS2D R5G delivers balanced performance: moderate trr (250ns) and VF (1.3V) with superior thermal resistance (55°C/W), making it optimal for general-purpose 50–200 kHz SMPS where reliability and manufacturability outweigh extreme speed or ultra-low VF.

FAQ
What is the maximum junction temperature rating for RS2D R5G?
The RS2D R5G has a maximum junction temperature (TJ) of +175°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows continuous operation in high-ambient environments such as enclosed industrial power modules. Derating begins above 75°C lead temperature, and the device maintains full 2A current capability up to 125°C TJ. The RS2D R5G's glass-passivated junction contributes to this extended thermal range.
Is RS2D R5G compatible with lead-free reflow soldering profiles?
Yes, RS2D R5G is fully compatible with standard lead-free reflow profiles (J-STD-020, peak 260°C). Its matte tin-plated leads meet J-STD-002 solderability requirements, and its moisture sensitivity level is rated Level 1-no baking is required prior to assembly. The DO-214AA (SMB) package withstands thermal cycling without delamination, and the RS2D R5G's UL 94V-0 molding compound ensures flame resistance during reflow.
What does the 'R5G' suffix in RS2D R5G indicate?
The 'R5G' suffix in RS2D R5G is Taiwan Semiconductor's internal ordering code variant denoting tape-and-reel packaging (3,000 units per reel) and green compound (halogen-free) construction. It does not alter electrical specifications-the core device remains the RS2D: 2A, 200V fast recovery rectifier in DO-214AA (SMB). All RS2D R5G units share identical VRRM, trr, VF, and thermal parameters as defined in the RS2A–RS2M family datasheet.
How does RS2D R5G compare to RS2G in terms of reverse voltage rating?
RS2D R5G is rated for 200V repetitive peak reverse voltage (VRRM), whereas RS2G is rated for 400V VRRM. Both share identical forward current (2A), thermal resistance (55°C/W), and reverse recovery time (250ns), but RS2G supports higher-input AC lines or wider input ranges (e.g., universal 85–305V AC). The RS2D R5G is optimized for cost-sensitive 200V-class applications like 115V-only adapters, while RS2G suits broader-input designs where margin against transients is critical.
Can RS2D R5G be used as a direct replacement for RS2B in an existing design?
RS2D R5G is not a direct replacement for RS2B without validation: RS2B has VRRM = 100V and identical trr = 250ns, but substituting RS2D R5G (200V) introduces unnecessary voltage margin and may affect layout parasitics due to higher junction capacitance (50pF vs. RS2B's typical 45pF). While electrically safe, the RS2D R5G's higher VRRM offers no benefit in 100V designs and could slightly increase EMI. Verify stress margins and thermal behavior before swapping RS2D R5G into an RS2B-designated board.
