Product details
Overview
HS3BB R5G from Taiwan Semiconductor is a 3A, 100V high-efficiency surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.0V max forward voltage at 3A, 100A surge rating, and 50ns reverse recovery time - deployed in AC/DC front-end stages of compact power adapters.
For engineers reviewing the HS3BB R5G datasheet, HS3BB R5G pinout, HS3BB R5G application, or HS3BB R5G equivalent, key selection criteria include VRRM=100V, IF=3A, low-profile SMB footprint, JESD201 Class 2 whisker resistance, and moisture sensitivity level 1 compliance.
Technical Context
This device is a single-die, glass-passivated, planar junction silicon rectifier optimized for high-frequency switching operation. Its 50ns trr and 1.0V VF at 3A support efficient energy transfer in discontinuous conduction mode (DCM) SMPS topologies.
Thermal performance is defined by RθJA = 60°C/W in free-air conditions, with junction temperature rated from –55°C to +150°C and UL 94V-0 mold compound ensuring flame-retardant reliability in enclosed power assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; sets safe operating margin in 12–24V input rectification. |
| IF | 3 A - Continuous average forward current; supports sustained output power up to ~36W in 12V adapter designs. |
| VF @ 3A | ≤1.0 V - Low conduction loss reduces thermal stress and improves efficiency in high-duty-cycle applications. |
| trr | ≤50 ns - Fast recovery minimizes switching losses and EMI generation in 65–130 kHz SMPS converters. |
| RθJA | 60 °C/W - Enables thermal design without heatsink in ambient ≤50°C for typical PCB layouts with 1-in² copper pour. |
| Moisture Sensitivity | Level 1 (J-STD-020) - No dry-bake required prior to reflow; compatible with standard SMT assembly lines. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC input or transformer secondary; must withstand 100A surge during cold-start. |
| Cathode | Forward current exit point | Connected to bulk capacitor positive rail; polarity marking ensures correct orientation on PCB. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | VRRM=60V, VF=0.95V @ 3A, trr=35ns, same SMB package | Limited to ≤60V systems; unsuitable for 100V-rated input designs | Select only when input voltage is capped at 42V RMS (e.g., 36VAC transformer). |
| SB3100 | VRRM=100V, VF=0.85V @ 3A, trr=35ns, SMB package, non-glass-passivated | Lower VF but reduced humidity robustness; not MSL Level 1 qualified | Prefer where thermal budget is tighter but environmental qualification is less critical. |
Compared with STTH3L06S and SB3100, HS3BB R5G uniquely balances 100V rating, MSL Level 1 handling, and glass passivation - making it optimal for cost-sensitive, high-reliability consumer power supplies requiring no pre-reflow baking.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS3BB R5G?
The HS3BB R5G has a VRRM of 100 V, verified in the Absolute Maximum Ratings table of the L2102 datasheet. This rating defines the highest reverse voltage the diode can block repeatedly without avalanche breakdown, making HS3BB R5G suitable for 100V-rated input circuits such as 70VAC–100VAC transformer secondaries or 100V DC bus clamping applications.
Does HS3BB R5G require moisture preconditioning before reflow soldering?
No - HS3BB R5G is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without baking. This eliminates process steps and reduces risk of intermetallic degradation, a key advantage over Level 2 or higher discrete diodes in high-throughput SMT lines.
What is the forward voltage drop of HS3BB R5G at its rated current?
HS3BB R5G exhibits a maximum forward voltage (VF) of 1.0 V at IF = 3 A and TJ = 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss for thermal design - actual VF decreases slightly at lower currents or elevated junction temperatures.
Is HS3BB R5G compatible with lead-free reflow profiles?
Yes - HS3BB R5G features matte tin-plated leads compliant with J-STD-002 and rated for peak reflow temperatures up to 260°C. Its DO-214AA (SMB) package uses UL 94V-0 molding compound, ensuring mechanical integrity and delamination resistance during JEDEC-standard lead-free reflow cycles.
What is the reverse recovery time (trr) specification for HS3BB R5G?
The reverse recovery time for HS3BB R5G is rated at ≤50 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery characteristic reduces switching losses and associated EMI in high-frequency SMPS designs, distinguishing HS3BB R5G from general-purpose rectifiers with trr > 100 ns.
