Product details
Overview
HS2G R5G from Taiwan Semiconductor is a 2 A, 400 V repetitive peak reverse voltage (VRRM) surface-mount fast recovery rectifier in DO-214AA (SMB) package, featuring 1.3 V max forward voltage at 2 A, 50 ns reverse recovery time, and 50 pF junction capacitance - deployed in AC/DC adapters and offline SMPS secondary-side rectification.
For engineers reviewing the HS2G R5G datasheet, HS2G R5G pinout, HS2G R5G application, or HS2G R5G equivalent, key selection criteria include VRRM = 400 V, IF = 2 A continuous, trr = 50 ns, thermal resistance RθJA = 80 °C/W, and DO-214AA mechanical compatibility with automated SMT placement.
Technical Context
The HS2G R5G uses a single-die, glass-passivated silicon junction optimized for fast switching in high-frequency power conversion. Its 50 ns reverse recovery time and 1.3 V forward voltage at 2 A enable reduced conduction and switching losses in 50–500 kHz SMPS topologies.
Designed for operation up to 150 °C junction temperature, it supports derated current handling across ambient temperatures and meets JESD201 Class 2 whisker resistance and RoHS/halogen-free compliance per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Withstands repetitive reverse voltage up to 400 V without breakdown in bridge or flyback secondary circuits. |
| IF | 2 A continuous - Rated average forward current under specified thermal conditions; supports 10–25 W adapter output stages. |
| trr | 50 ns - Fast recovery enables efficient operation in 100–300 kHz switching converters with minimal tail current loss. |
| VF | ≤1.3 V @ 2 A, 25°C - Low conduction drop reduces power dissipation and thermal stress in compact SMB layouts. |
| CJ | 50 pF @ 1 MHz, 4 V - Junction capacitance impacts EMI filtering design and snubber sizing in high-dv/dt applications. |
| RθJA | 80 °C/W - Thermal resistance defines required PCB copper area and airflow for maintaining TJ ≤ 150°C at full load. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R04 | VRRM = 400 V, trr = 35 ns, VF = 1.25 V @ 2 A - faster but higher cost | Better suited for >200 kHz resonant converters where trr dominates loss | Select STTH2R04 when minimizing switching loss outweighs cost sensitivity and layout constraints allow same SMB footprint. |
| ON Semi MUR240 | VRRM = 400 V, trr = 50 ns, VF = 1.3 V @ 2 A - identical recovery, slightly higher leakage at 125°C | Same thermal and electrical envelope; qualified for automotive-grade temp cycling | Choose MUR240 for designs requiring AEC-Q101 qualification or extended high-temp reliability validation. |
Compared with STTH2R04 and MUR240, the HS2G R5G delivers matching 400 V/2 A/50 ns performance at lower unit cost and with halogen-free compliance, making it optimal for cost-sensitive industrial and commercial power supplies where AEC-Q101 is not mandated.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for HS2G R5G?
The HS2G R5G has a VRRM of 400 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version L2102). This rating ensures reliable blocking capability in 230 V AC-derived circuits with sufficient safety margin against line transients and ripple peaks. The HS2G R5G must not be operated beyond this voltage in repetitive mode.
Does HS2G R5G have a defined forward voltage (VF) specification, and under what conditions?
Yes, HS2G R5G specifies a maximum forward voltage of 1.3 V at IF = 2 A and TJ = 25°C, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At elevated junction temperatures or higher currents, VF increases predictably per the device's forward characteristic curve.
What is the reverse recovery time (trr) of HS2G R5G, and how is it tested?
The HS2G R5G has a typical reverse recovery time of 50 ns, measured under the condition IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as defined in the datasheet's Electrical Specifications section. This test method reflects real-world switching behavior in hard-commutated converters and directly impacts switching loss and EMI profile in high-frequency designs using HS2G R5G.
Is HS2G R5G compliant with RoHS and halogen-free standards?
Yes, HS2G R5G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the Features section of the Taiwan Semiconductor datasheet. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead-free matte tin plating meets J-STD-002 solderability requirements - critical for HS2G R5G deployment in EU and Asia-Pacific markets.
What package type does HS2G R5G use, and what are its key mechanical attributes?
HS2G R5G uses the DO-214AA (SMB) package, with dimensions and pad layout defined in the Package Outline Dimensions drawing (Version L2102). Key attributes include UL 94V-0 flammability rating, JESD201 Class 2 whisker resistance, cathode band polarity marking, and 0.090 g typical weight - all verified in the Mechanical Data section and essential for HS2G R5G's SMT assembly and thermal management.
