Product details
Overview
RS2BAHR3G 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 capability. It serves as a primary output rectifier in DC-DC converters and switching-mode power supplies where efficiency and thermal robustness are critical.
For engineers reviewing the RS2BAHR3G datasheet, RS2BAHR3G pinout, RS2BAHR3G application, or RS2BAHR3G 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 DO-214AC mechanical compatibility with automated placement.
Technical Context
This device is a single-die, glass-passivated silicon PN junction rectifier optimized for fast switching in high-frequency power conversion. Its 150 ns trr and low 50 pF junction capacitance support operation in 100–500 kHz SMPS topologies without excessive switching loss or EMI generation.
The DO-214AC (SMA) package provides a thermally efficient path via the cathode band-marked leads, enabling reliable operation up to 175 °C junction temperature. Matte tin-plated terminals meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback or forward converter secondary-side rectification |
| IF | 1.5 A - Continuous average forward current; sets steady-state power handling limit at TA = 75°C with derating |
| trr | 150 ns - Reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; directly impacts switching loss and snubber sizing |
| VF | ≤1.3 V @ 1.5 A, 25°C - Forward voltage drop; determines conduction loss and thermal load under full load |
| RθJL | 18 °C/W - Junction-to-lead thermal resistance; enables accurate thermal design when mounted on PCB copper pour |
| IR | ≤5 µA @ 100 V, 25°C - Max reverse leakage; critical for low-power standby modes and high-impedance bias networks |
Pinout & Package
DO-214AC (SMA) surface-mount package with axial lead configuration: cathode indicated by molded band; anode and cathode terminals form a two-terminal unidirectional current path. Leads are matte tin-plated per J-STD-002, compliant with JESD201 Class 2 whisker testing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction | Connected to lower-potential node (e.g., transformer secondary center-tap or ground return) |
| Cathode | Output terminal for forward conduction | Marked with band; connects to output capacitor positive rail or load input |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable long-term reliability under humidity and thermal cycling stress per J-STD-020 Level 1 |
| Fast recovery (150 ns) | Reduces switching loss in 100–300 kHz DC-DC converters versus standard rectifiers (>500 ns) |
| Moisture sensitivity Level 1 | Eliminates need for dry-packaging or baking prior to reflow; supports standard SMT line flow |
| RoHS and halogen-free | Meets IPC-1752A environmental compliance for industrial and consumer end-equipment |
Applications
| DC-DC Converter Output Rectification | Switching Mode Inverter Snubber |
|---|---|
Use Scenario: Secondary-side rectification in isolated 12 V/1.5 A buck-derived flyback converter powering industrial I/O modules. IC Role / Device Role / Timing Role: Unidirectional current valve converting high-frequency AC from transformer secondary into regulated DC output. Use Value: 150 ns trr minimizes reverse recovery charge (Qrr), reducing MOSFET turn-on loss and improving overall efficiency by ~0.8% at 200 kHz. | Use Scenario: RC snubber network across IGBT collector-emitter in 400 V, 10 kHz motor drive inverter stage. IC Role / Device Role / Timing Role: Fast clamping diode providing low-impedance discharge path for snubber capacitor during IGBT turn-off. Use Value: 1.3 V VF and 50 A IFSM ensure robust transient energy absorption without voltage overshoot exceeding 120% of bus voltage. |
| LED Driver Secondary Rectification | General-Purpose AC Line Input Bridge Leg |
Use Scenario: Output rectifier in constant-current 24 V LED driver for commercial lighting, operating at 250 kHz PWM frequency. IC Role / Device Role / Timing Role: High-efficiency rectifier delivering stable DC to constant-current regulator IC. Use Value: 175 °C TJ max and 18 °C/W RθJL allow operation at 95 °C ambient without derating, supporting compact enclosed fixture designs. | Use Scenario: Single-leg replacement in discrete 4-diode bridge rectifier for 24 VAC control circuitry in HVAC thermostats. IC Role / Device Role / Timing Role: Half-wave rectifier providing pulsed DC to linear regulator input. Use Value: DO-214AC footprint ensures direct compatibility with existing SMA pad layout; 100 V VRRM exceeds 24 VAC × √2 × 1.2 safety margin. |
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; faster recovery but smaller current rating | Preferred where higher voltage margin and lower Qrr are prioritized over current capacity |
| MBR15100CT | 15 A, 100 V, dual common-cathode Schottky, TO-220AC | Higher current, lower VF (~0.85 V), but no reverse blocking in Schottky configuration | Suitable only in low-VF, low-loss forward-conduction roles-not for reverse-biased snubbers or AC line rectification |
Compared with RS2BAHR3G, STTH1L06U offers superior voltage headroom and speed but requires layout change due to TO-277 footprint and delivers only 1 A continuous current; MBR15100CT provides higher current and lower conduction loss but lacks reverse blocking capability, limiting use to unidirectional forward paths only.

FAQ
What is the maximum junction temperature rating for RS2BAHR3G?
The RS2BAHR3G has a maximum junction temperature (TJ) rating of +175 °C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version I2304. This allows sustained operation in high-ambient environments such as enclosed LED drivers or industrial power supplies when properly heatsinked via PCB copper pour. The RS2BAHR3G must not exceed this limit under any steady-state or transient condition.
Does RS2BAHR3G have a halogen-free and RoHS-compliant construction?
Yes, RS2BAHR3G is explicitly certified halogen-free and RoHS compliant per the manufacturer's documentation (Version I2304). The molding compound meets UL 94V-0 flammability rating, and the matte tin-plated leads satisfy J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements. These attributes are confirmed in the "Features" and "Mechanical Data" sections of the RS2BAHR3G datasheet.
What is the reverse recovery time (trr) specification for RS2BAHR3G?
The RS2BAHR3G has a reverse recovery time (trr) of 150 ns, measured under conditions IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as specified in the Electrical Specifications table of the Taiwan Semiconductor datasheet (Version I2304). This value is confirmed for the RS2BA variant group and applies directly to RS2BAHR3G, enabling predictable switching loss calculation in high-frequency power converters.
Is RS2BAHR3G compatible with standard reflow soldering processes?
Yes, RS2BAHR3G is rated J-STD-020 Moisture Sensitivity Level 1, meaning it can be subjected to standard Pb-free reflow profiles (e.g., JEDEC J-STD-020D peak of 260 °C) without pre-baking. Its matte tin-plated leads comply with J-STD-002 for solderability, and the DO-214AC package is qualified for automated placement and reflow. No special handling is required beyond standard SMT line controls.
What does the 'HR3G' suffix indicate in RS2BAHR3G?
The 'HR3G' suffix in RS2BAHR3G denotes Taiwan Semiconductor's internal packaging and environmental coding: 'H' indicates halogen-free compound, 'R3' specifies tape-and-reel packaging (7,500 units per reel), and 'G' signifies green (lead-free/RoHS-compliant) marking. This suffix aligns with TSC's ordering nomenclature in the "Ordering Information" section of the RS2AA–RS2MA datasheet (Version I2304).
