Product details
Overview
HS2D R5G from Taiwan Semiconductor is a 2 A, 200 V high-efficiency surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.0 V forward voltage at 2 A, 50 ns reverse recovery time, and glass-passivated junction for reliability in switching power supplies.
For engineers reviewing the HS2D R5G datasheet, HS2D R5G pinout, HS2D R5G application, or HS2D R5G equivalent, this page delivers verified electrical specs, thermal performance, polarity marking, JEDEC-compliant packaging, and real-world use context for SMPS, adapters, lighting converters, and industrial DC-DC stages.
Technical Context
The HS2D R5G is a single-die, fast-recovery rectifier optimized for high-frequency switching operation. Its 50 ns trr and low 1.0 V VF at 2 A reduce conduction and switching losses, while the glass-passivated junction ensures stable performance across -55°C to +150°C junction temperature range.
Designed for automated SMT assembly, it meets J-STD-002 solderability and JESD201 Class 2 whisker resistance. The cathode band marking and matte tin-plated leads support reliable polarity identification and reflow compatibility in high-volume production.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage; defines safe blocking capability in flyback or boost topologies |
| IF | 2 A - Continuous forward current rating; supports sustained output rectification in 20–50 W SMPS designs |
| VF @ 2 A | 1.0 V - Forward voltage drop at rated current; directly determines conduction loss (2.0 W max at full load) |
| trr | 50 ns - Reverse recovery time; enables efficient operation up to ~500 kHz switching frequencies |
| RθJA | 80 °C/W - Junction-to-ambient thermal resistance; requires minimal PCB copper area for thermal management |
| IR @ 25°C | 5 µA - Max reverse leakage at rated VR; ensures low standby power loss in offline converters |

Applications
| AC-DC Adapter Rectification | LED Driver Secondary Side |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast-recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02U (STMicroelectronics) | Same 2 A / 200 V rating; VF = 0.95 V typ, trr = 35 ns - faster but higher cost | Better suited for >300 kHz designs where lower trr reduces EMI filtering burden | Select when optimizing for ultra-low switching loss and can accommodate tighter layout tolerances |
| ES2D (ON Semiconductor) | 2 A / 200 V; VF = 1.15 V max, trr = 35 ns; DO-214AA package with identical pinout | Higher VF increases conduction loss; slightly better trr but less thermal margin (RθJA = 85 °C/W) | Acceptable for cost-sensitive adapters where 0.15 V VF delta is acceptable and board space is constrained |
Compared with STTH2R02U and ES2D, the HS2D R5G offers balanced performance: lower VF than ES2D and better thermal resistance than both, making it optimal for thermally constrained 20–100 W SMPS where reliability and manufacturability are prioritized over marginal speed gains.

FAQ
What is the maximum junction temperature rating for the HS2D R5G?
The HS2D R5G has a maximum junction temperature (TJ MAX) of +150°C, with operational range from -55°C to +150°C. This rating enables reliable use in enclosed power adapters and LED drivers where internal temperatures may exceed 85°C ambient. Derating curves in the datasheet confirm 2 A continuous current is maintainable up to 115°C case temperature under natural convection.
Does the HS2D R5G have a specified reverse recovery time, and how is it measured?
Yes, the HS2D R5G has a reverse recovery time (trr) of 50 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC test conditions. This value is confirmed in the Electrical Specifications table on page 2 of the L2102 datasheet. The 50 ns trr supports efficient operation in 100–500 kHz switching applications without excessive switching loss.
Is the HS2D R5G RoHS compliant and halogen-free?
Yes, the HS2D R5G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound and lead finish meet these requirements, and the device carries the "G" suffix in its marking code (HS2D R5G) to indicate green compound. This makes HS2D R5G suitable for export to EU, Japan, and other regulated markets requiring strict environmental compliance.
What does the "R5G" suffix in HS2D R5G signify?
The "R5G" suffix in HS2D R5G identifies the specific manufacturing variant: "R5" denotes reel packaging (3,000 pcs/tape-and-reel), and "G" indicates halogen-free, RoHS-compliant green molding compound. This suffix is part of Taiwan Semiconductor's standardized ordering code system and appears on the device body as part of the full marking sequence.
Can the HS2D R5G replace the HS2B or HS2F in an existing design?
No - HS2D R5G is rated for 200 V VRRM, while HS2B is 100 V and HS2F is 300 V. Substituting across voltage grades risks premature failure under reverse bias. Only direct replacements within the same voltage grade (e.g., HS2D for HS2D variants) are recommended. Always verify reverse voltage margin, thermal performance, and VF matching before interchanging any HS2x series devices.
