Product details
Overview
HS2F from Taiwan Semiconductor is a 300 V repetitive peak reverse voltage, 2 A average forward current, surface-mount fast recovery rectifier in DO-214AA (SMB) package, featuring 1.0 V typical forward voltage at 2 A and 50 ns reverse recovery time - used in high-efficiency AC/DC adapters and offline SMPS secondary-side rectification.
For engineers reviewing the HS2F datasheet, HS2F pinout, HS2F application, or HS2F equivalent, key selection criteria include its 300 V VRRM, 50 A surge rating, 80 °C/W junction-to-ambient thermal resistance, RoHS/halogen-free compliance, and SMB footprint compatibility with automated SMT assembly.
Technical Context
The HS2F is a single-die, glass-passivated silicon PN junction rectifier optimized for fast switching in high-frequency power conversion. Its 50 ns reverse recovery time and low 1.0 V forward voltage at 2 A enable reduced conduction and switching losses in 50–500 kHz SMPS topologies.
Thermally rated for 150 °C maximum junction temperature and housed in UL 94V-0 molded DO-214AA (SMB) package, the HS2F supports continuous operation under derated forward current above 75 °C ambient, with cathode polarity indicated by a visible band.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R03 | Same 300 V VRRM, 2 A IF, but 35 ns trr and 1.15 V VF; DO-214AA package | Better switching speed but higher conduction loss; preferred in >300 kHz resonant converters | Select STTH2R03 when trr-driven EMI reduction outweighs VF-driven thermal margin |
| ON Semi MUR230 | 300 V VRRM, 2 A IF, 50 ns trr, but 1.3 V VF; same DO-214AA footprint | Higher forward drop increases thermal stress at full load; identical surge and thermal ratings | Choose MUR230 only if dual-sourcing across multiple suppliers is required with no layout change |
Compared with STTH2R03 and MUR230, the HS2F delivers the lowest forward voltage (1.0 V) among 300 V/2 A SMB rectifiers, offering superior thermal performance in space-constrained adapters and lighting drivers where conduction loss dominates.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS2F?
The HS2F has a maximum repetitive peak reverse voltage (VRRM) of 300 V, as specified in the absolute maximum ratings table. This rating ensures reliable blocking capability in 230 VAC-derived circuits with safety margin, including surge conditions up to 264 VAC RMS. The HS2F must not be operated beyond this voltage to prevent avalanche breakdown or catastrophic failure.
Does HS2F support automated pick-and-place assembly?
Yes, the HS2F supports automated placement per J-STD-002 standards. Its DO-214AA (SMB) package features matte tin-plated leads, defined coplanarity, and standardized tape-and-reel packaging (3,000 units per reel), making it compatible with high-speed SMT lines. The device's 0.090 g weight and symmetrical lead geometry further enhance placement yield.
What is the typical forward voltage (VF) of HS2F at rated current?
The typical forward voltage (VF) of HS2F is 1.0 V at 2 A forward current and 25 °C junction temperature. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects low conduction loss ideal for thermally constrained designs. At 100 °C junction temperature, VF decreases slightly due to negative temperature coefficient of silicon PN junctions.
Is HS2F compliant with RoHS and halogen-free requirements?
Yes, HS2F is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants, and the matte tin plating meets JEDEC J-STD-002B solderability requirements. These attributes are confirmed in the official TSC L2102 datasheet revision and supported by TSC's material declarations.
What is the reverse recovery time (trr) specification for HS2F?
The reverse recovery time (trr) for HS2F is 50 ns maximum, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery characteristic reduces switching losses and EMI generation in high-frequency power converters, distinguishing HS2F from standard recovery rectifiers that typically exceed 250 ns.
