Product details
Overview
RS2BA R3G from Taiwan Semiconductor is a 1.5A, 100V fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 150 ns reverse recovery time, 1.3 V max forward voltage at 1.5 A, and 50 A peak surge current. It serves as a primary output rectifier in DC-DC converters and switching inverters where efficiency and thermal robustness are critical.
For engineers reviewing the RS2BA R3G datasheet, RS2BA R3G pinout, RS2BA R3G application, or RS2BA R3G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), junction-to-lead thermal resistance (18 °C/W), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and cathode-band polarity marking for automated assembly verification.
Technical Context
This discrete diode employs a glass-passivated silicon junction optimized for fast switching in high-frequency power conversion topologies. Its 150 ns trr and low 50 pF junction capacitance enable reduced switching losses in 100–500 kHz SMPS designs.
The device operates across –55°C to +175°C junction temperature range with 1.3 V VF max at rated current and exhibits only 5 µA IR at 25°C - supporting stable performance in thermally constrained lighting and snubber circuits.
Key Specifications

| RθJL | 18 °C/W - allows direct PCB copper pour heatsinking for reliable 1.5 A operation without external heatsink |
| IR (25°C) | 5 µA - ensures minimal leakage in high-impedance snubber or hold-up circuits |
| MSL | Level 1 (J-STD-020) - compatible with standard reflow profiles, no dry-pack required |

Applications
| DC-DC Converter Output Rectification | Switching Inverter Freewheeling Diode |
|---|---|
Use Scenario: Secondary-side rectification in isolated 12–48 V input, 3.3–24 V output flyback or forward converters. IC Role / Device Role / Timing Role: Unidirectional current valve converting high-frequency AC from transformer into regulated DC output. Use Value: 150 ns trr minimizes switching loss overlap with synchronous MOSFET gate drive, improving efficiency by 0.8–1.2% over slower 500 ns diodes. | Use Scenario: Freewheeling path for inductive loads in 100–200 kHz H-bridge inverters driving LED drivers or small motors. IC Role / Device Role / Timing Role: Provides low-loss return path during MOSFET off-time, clamping inductive kickback. Use Value: 1.3 V VF max limits conduction loss to ≤1.95 W at 1.5 A, reducing heatsink size versus 1N5822-class Schottkys in same footprint. |
| LED Driver Snubber Network | General-Purpose AC/DC Bridge Leg |
Use Scenario: RC snubber clamp across primary-side MOSFET or secondary-side rectifier in constant-current LED drivers. IC Role / Device Role / Timing Role: Absorbs transient energy during switching transitions, suppressing voltage spikes. Use Value: 100 V VRRM and 50 A IFSM withstand repeated 60–100 V transients without degradation, extending snubber lifetime. | Use Scenario: Single-diode leg in compact, low-cost bridge rectifiers for 12–24 V AC adapter front-ends. IC Role / Device Role / Timing Role: Half-wave rectification element in discrete bridge configurations requiring tight footprint control. Use Value: DO-214AC (SMA) package fits same PCB area as 1N400x but delivers 3× higher surge rating and 5× faster recovery. |
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 | 1 A, 600 V, 75 ns trr, TO-277 package | Higher VRRM but lower IF; requires different footprint and thermal layout | Prefer when >400 V blocking is needed and current demand ≤1 A |
| ES1B | 1 A, 100 V, 35 ns trr, DO-214AA (SMB) package | Faster recovery but 33% lower IF rating; smaller thermal mass | Select for ultra-fast switching below 1 A, where 150 ns trr is acceptable margin |
Compared with STTH1L06U and ES1B, RS2BA R3G uniquely balances 1.5 A current capability, 100 V rating, and 150 ns recovery in the industry-standard DO-214AC footprint - making it optimal for cost-sensitive, medium-power 48 V system rectification where thermal headroom and assembly compatibility are prioritized.

FAQ
What is the maximum junction temperature rating for RS2BA R3G?
The RS2BA R3G has a maximum junction temperature (TJ MAX) of +175°C, enabling reliable operation in high-ambient environments such as enclosed LED drivers or industrial power supplies. This rating is validated per TSC's absolute maximum ratings table and supported by its 18 °C/W junction-to-lead thermal resistance - allowing sustained 1.5 A conduction with appropriate PCB copper area. The RS2BA R3G must not exceed this limit during steady-state or transient conditions.
Does RS2BA R3G meet RoHS and halogen-free requirements?
Yes, RS2BA R3G is RoHS compliant and halogen-free per TSC's product documentation and material declarations. The molding compound and matte tin plating satisfy IPC-1752A reporting standards, and the device carries no restricted substances above EU RoHS thresholds. This compliance is confirmed in the "Features" section of the official RS2AA–RS2MA datasheet (Version I2304), and applies identically to all variants including RS2BA R3G.
What is the reverse recovery time (trr) specification for RS2BA R3G?
The RS2BA R3G has a maximum reverse recovery time (trr) of 150 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the datasheet's Electrical Specifications table. This value is shared with RS2AA and RS2DA variants and is confirmed in the "Reverse recovery time" row of the parameter table. The RS2BA R3G's 150 ns trr supports efficient operation in 100–500 kHz switching applications without excessive switching loss.
Is RS2BA R3G suitable for use in DC-DC converter output stages?
Yes, RS2BA R3G is explicitly recommended for DC-DC converter output rectification per TSC's Applications list. Its 1.5 A average forward current, 100 V VRRM, 150 ns trr, and 1.3 V VF max align with common 12–48 V input, 3.3–24 V output flyback and forward converter requirements. The RS2BA R3G's DO-214AC package also provides adequate thermal dissipation for these power levels without additional heatsinking.
What does the 'R3G' suffix indicate in RS2BA R3G?
The 'R3G' suffix in RS2BA R3G denotes Taiwan Semiconductor's internal tape-and-reel packaging variant: R3 = 7,500 pcs per reel, G = green compound (halogen-free molding). This matches the Ordering Information table stating "RS2xA" is supplied in DO-214AC (SMA) package, 7,500/reel. The electrical and thermal specifications of RS2BA R3G are identical to RS2BA without suffix - only packaging and material composition differ.
