Product details
Overview
HS2K R5G from Taiwan Semiconductor is a 800 V repetitive peak reverse voltage, 2 A average forward current surface-mount fast recovery rectifier in DO-214AA (SMB) package, featuring 1.7 V max forward voltage at 2 A and 75 ns reverse recovery time, used in high-efficiency AC/DC converters and LED lighting power stages.
For engineers reviewing the HS2K R5G datasheet, HS2K R5G pinout, HS2K R5G application, or HS2K R5G equivalent, key selection criteria include VRRM=800 V, IF=2 A, VF≤1.7 V, trr=75 ns, and DO-214AA thermal resistance of 80 °C/W under natural convection.
Technical Context
This device is a single-die, glass-passivated silicon junction rectifier optimized for switching-mode power conversion. Its 75 ns reverse recovery time and low junction capacitance (30 pF at 4 V) support operation in 50–500 kHz SMPS topologies without excessive switching loss.
The DO-214AA (SMB) package provides 80 °C/W junction-to-ambient thermal resistance and supports automated placement with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Withstands up to 800 V repetitive reverse voltage, suitable for 400 V DC bus designs with safety margin. |
| IF(AV) | 2 A - Continuous forward current rating at TA = 75 °C, enabling compact 20–40 W adapter designs. |
| VF(max) | 1.7 V @ 2 A, 25 °C - Low conduction loss improves efficiency in high-frequency flyback and boost converters. |
| trr | 75 ns - Fast recovery minimizes reverse recovery charge (Qrr), reducing EMI and MOSFET stress in hard-switched topologies. |
| RθJA | 80 °C/W - Enables thermal design with minimal copper area on standard FR-4 PCBs without heatsinking. |
| CJ | 30 pF @ 1 MHz, VR = 4 V - Low junction capacitance limits displacement current during high dv/dt switching transitions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R08 | VRRM=800 V, IF=2 A, VF=1.75 V, trr=70 ns, DO-214AA | Slightly faster trr but higher VF; same thermal performance | Preferred where lower Qrr dominates over conduction loss |
| ON Semi MUR280 | VRRM=800 V, IF=2 A, VF=1.85 V, trr=75 ns, DO-214AA | Higher VF increases conduction loss; identical surge and thermal specs | Valid alternative when STTH2R08 is unavailable; verify layout thermal relief |
Compared with STTH2R08 and MUR280, HS2K R5G offers the lowest VF among 800 V/2 A SMB rectifiers in its family, delivering superior efficiency in thermally constrained adapters and lighting drivers without sacrificing surge robustness or recovery speed.

FAQ
What is the maximum junction temperature rating for HS2K R5G?
The HS2K R5G has a maximum junction temperature (TJ) rating of +150 °C, allowing continuous operation in high-ambient environments such as enclosed LED drivers or industrial control enclosures. This rating is validated per JEDEC JESD22-A108 and supported by its 80 °C/W thermal resistance in standard DO-214AA mounting conditions. Derating begins above 75 °C ambient per the forward current derating curve in the HS2K R5G datasheet.
Does HS2K R5G meet RoHS and halogen-free requirements?
Yes, HS2K R5G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and the matte tin-plated leads satisfy J-STD-002 solderability standards. These qualifications are confirmed in Taiwan Semiconductor's L2102 revision documentation for the HS2x family.
What is the reverse recovery time (trr) specification for HS2K R5G?
The HS2K R5G has a maximum reverse recovery time (trr) of 75 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC test conditions. This value is typical for the HS2J–HS2M subgroup and enables efficient operation in 100–500 kHz switching power supplies without excessive switching loss or EMI generation.
Can HS2K R5G replace HS2J or HS2M in an existing design?
HS2K R5G can replace HS2J (600 V) in designs requiring higher reverse voltage margin, and may substitute for HS2M (1000 V) only if the circuit's peak reverse voltage remains ≤800 V. It shares identical DO-214AA package, pinout, and thermal characteristics across the HS2J–HS2M group, but VF and trr values are matched within subgroups-HS2K R5G uses the same die as HS2J and HS2M.
What is the surge current rating (IFSM) for HS2K R5G?
The HS2K R5G has a non-repetitive peak forward surge current (IFSM) rating of 50 A for an 8.3 ms single half-sine wave, as specified in the absolute maximum ratings table. This rating ensures robustness against inrush currents during cold-start in AC/DC power supplies and allows use without additional series fusing in most 230 VAC-input applications.
