Product details
Overview
HS3DB R5G from Taiwan Semiconductor is a 3 A, 200 V repetitive peak reverse voltage (VRRM) surface-mount fast recovery rectifier in DO-214AA (SMB) package, featuring 1.0 V max forward voltage at 3 A, 50 ns reverse recovery time, and glass passivated junction for reliability in high-efficiency SMPS and adapters.
For engineers reviewing the HS3DB R5G datasheet, HS3DB R5G pinout, HS3DB R5G application, or HS3DB R5G equivalent, key selection criteria include VRRM = 200 V, IF = 3 A, trr = 50 ns, VF ≤ 1.0 V, and DO-214AA thermal resistance of 60 °C/W - all critical for compact, thermally constrained power conversion designs.
Technical Context
This device is a single-die, unidirectional silicon rectifier optimized for high-frequency switching operation. Its 50 ns reverse recovery time and low 1.0 V forward voltage drop minimize conduction and switching losses in 50–500 kHz SMPS topologies.
The DO-214AA (SMB) package provides robust thermal performance (RθJA = 60 °C/W) and moisture sensitivity level 1 handling, with matte tin-plated leads compliant to J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - supports input rectification up to 200 V DC or 141 V RMS AC without breakdown |
| IF | 3 A continuous - rated average forward current for sustained conduction in adapter/SMPS output stages |
| trr | 50 ns - enables efficient operation in high-frequency flyback and forward converters with minimal switching loss |
| VF | ≤1.0 V @ 3 A, 25°C - reduces conduction loss and self-heating in space-constrained PCB layouts |
| RθJA | 60 °C/W - allows ~2.5 W dissipation at 75°C ambient before reaching 150°C junction limit |
| Junction Temp | −55°C to +150°C - supports operation in industrial ambient environments and under transient load conditions |
Pinout & Package
DO-214AA (SMB) surface-mount package with cathode-indicated band; dual-leaded, gull-wing configuration; 0.093 g mass; UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |

| Anode | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or bridge leg) |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output rail or filter capacitor positive; blocks 200 V reverse bias |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery (trr = 50 ns) | Reduces switching loss and EMI generation in >100 kHz power supplies |
| Glass passivated junction | Enhances long-term reliability and humidity resistance in reflow-soldered assemblies |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to SMT assembly, reducing process cost and risk |

Applications
| Laptop Adapter Power Stage | LED TV Secondary Rectification |
|---|---|
Use Scenario: High-density 65 W laptop AC/DC adapter with synchronous rectification disabled. IC Role / Device Role / Timing Role: Output rectifier converting high-frequency transformer secondary AC to regulated DC bus. Use Value: 50 ns trr and 1.0 V VF reduce output stage loss by ~12% vs. standard recovery diodes, improving efficiency to >89% at full load. | Use Scenario: 120 W LED backlight power supply in 55″ smart TV with tight thermal envelope. IC Role / Device Role / Timing Role: Main output rectifier in quasi-resonant flyback converter operating at 120 kHz. Use Value: DO-214AA package and 60 °C/W RθJA enable direct mounting on copper pour, limiting junction rise to <85°C at 3 A continuous. |
| Industrial SMPS Auxiliary Supply | Monitor Standby Power Converter |
Use Scenario: 15 W auxiliary supply powering control logic and gate drivers in PLC power module. IC Role / Device Role / Timing Role: Input rectifier for isolated buck-derived auxiliary winding feeding linear regulator. Use Value: 200 V VRRM safely withstands reflected transients up to 180 V, eliminating need for snubber network. | Use Scenario: Ultra-low standby power (<300 mW) monitor auxiliary supply meeting ENERGY STAR v7.0. IC Role / Device Role / Timing Role: High-efficiency output rectifier in discontinuous conduction mode (DCM) flyback. Use Value: Low 10 μA IR at 25°C minimizes no-load leakage loss, contributing to sub-100 mW standby consumption. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L02 | VRRM = 200 V, trr = 45 ns, VF = 0.95 V @ 3 A - slightly faster, lower VF, but RθJA = 65 °C/W | Marginally better efficiency in high-frequency designs; higher thermal resistance may require larger pad | Preferred where trr < 45 ns is required and board area permits enhanced thermal pad |
| ON Semi MUR320 | VRRM = 200 V, trr = 55 ns, VF = 1.05 V @ 3 A - slower recovery, higher VF, same DO-214AA package | Higher conduction loss and switching loss; suitable only when cost is primary constraint | Acceptable for <100 kHz designs where 5 ns trr margin is noncritical and thermal budget is generous |
Compared with STTH3L02 and MUR320, the HS3DB R5G delivers balanced performance: its 50 ns trr and 1.0 V VF match mid-tier efficiency targets while maintaining 60 °C/W thermal resistance - making it optimal for cost-sensitive, thermally constrained 100–200 kHz SMPS where neither ultra-low VF nor extreme speed is mandatory.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS3DB R5G?
The HS3DB R5G has a VRRM rating of 200 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version L2102). This value defines the highest reverse voltage the device can block repeatedly without avalanche breakdown, making it suitable for 141 V RMS AC inputs or 200 V DC bus applications. Exceeding this rating risks irreversible junction failure.
Does HS3DB R5G have a specified reverse recovery time (trr)?
Yes, the HS3DB R5G has a maximum reverse recovery time of 50 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as stated in the Electrical Specifications section. This trr value is consistent across the HS3AB–HS3GB subgroup and directly impacts switching loss in high-frequency converters.
What package type does HS3DB R5G use, and what are its key mechanical attributes?
The HS3DB R5G uses the DO-214AA (SMB) surface-mount package. Key attributes include matte tin-plated leads compliant to J-STD-002, UL 94V-0 flammability-rated molding compound, polarity indicated by cathode band, and a weight of approximately 0.093 g. The package supports automated placement and meets JESD 201 Class 2 whisker resistance.
Is HS3DB R5G compliant with RoHS and halogen-free standards?
Yes, HS3DB R5G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. These compliance statements apply to the full HS3x family, including HS3DB R5G, and are verified through material declarations and third-party testing.
What is the junction-to-ambient thermal resistance (RθJA) for HS3DB R5G?
The junction-to-ambient thermal resistance for HS3DB R5G is 60 °C/W, measured under standard JEDEC conditions for the DO-214AA package. This value assumes a standard 1-inch² copper pad on the PCB and is critical for calculating allowable power dissipation - for example, at 75°C ambient, HS3DB R5G can dissipate up to 2.5 W before reaching its 150°C maximum junction temperature.
