Product details

Overview

HS2G from Taiwan Semiconductor is a 2 A, 400 V repetitive peak reverse voltage (V_RRM) surface-mount fast recovery rectifier in DO-214AA (SMB) package, with 1.3 V forward voltage at 2 A, 50 ns reverse recovery time, and 50 pF junction capacitance at 1 MHz / 4.0 V reverse bias - used in high-efficiency SMPS secondary-side rectification.

For engineers reviewing the HS2G datasheet, HS2G pinout, HS2G application, or HS2G equivalent, key selection criteria include its 400 V V_RRM, 50 ns trr for high-frequency switching, 50 pF C_J at 1 MHz/4.0 V, thermal resistance of 80 °C/W, and DO-214AA mechanical compatibility in compact power adapters and LED drivers.

Technical Context

The HS2G is a single-die, glass-passivated silicon junction rectifier optimized for fast recovery in high-frequency DC/DC conversion stages. Its 50 ns reverse recovery time and low 50 pF junction capacitance at 1 MHz/4.0 V support efficient operation up to several hundred kHz in flyback and forward converters.

Rated for 2 A average forward current and 50 A non-repetitive surge, the device operates across –55 °C to +150 °C junction temperature range with 80 °C/W junction-to-ambient thermal resistance in standard SMB mounting conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - supports 400 V DC blocking in secondary-side rectification of offline SMPS with safety margin
I_F	2 A - continuous forward current rating suitable for mid-power adapter outputs (e.g., 12–24 V @ ~1.5–2 A)
t_rr	50 ns - enables efficient high-frequency switching (>200 kHz) with reduced switching loss and EMI
C_J	50 pF @ 1 MHz, 4.0 V - low junction capacitance minimizes capacitive coupling and dynamic losses in fast-switching nodes
V_F	1.3 V @ 2 A, 25 °C - forward drop impacts conduction loss and thermal design in thermally constrained SMB footprint
R_θJA	80 °C/W - defines thermal rise under natural convection; requires PCB copper area planning for 2 A continuous operation

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	Same 2 A / 400 V rating; 1.25 V V_F, 45 ns t_rr, DO-214AA package	Slightly lower V_F and faster t_rr; higher cost and longer lead time	Preferred where <5 ns t_rr reduction justifies sourcing complexity
ON Semi MUR240	2 A / 400 V; 1.3 V V_F, 50 ns t_rr, but DO-201AD (axial) package	Requires through-hole assembly; not compatible with SMT-only production	Select only if legacy axial layout or manual repair constraints apply

Compared with STTH2R04 and MUR240, the HS2G offers identical electrical performance to MUR240 in V_F and t_rr but with SMT-ready DO-214AA packaging, while delivering better thermal resistance than STTH2R04 in standard PCB layouts due to optimized SMB pad thermal coupling.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for HS2G?

The HS2G has a maximum repetitive peak reverse voltage (V_RRM) of 400 V, as specified in the absolute maximum ratings table of the official Taiwan Semiconductor datasheet (Version L2102). This rating defines the highest reverse voltage the device can block repeatedly without breakdown and is critical for selecting appropriate safety margins in offline SMPS designs using the HS2G.

What is the forward voltage (V_F) of HS2G at rated current?

The HS2G exhibits a maximum forward voltage (V_F) of 1.3 V at 2 A forward current and 25 °C junction temperature, per the electrical specifications table. This value directly impacts conduction loss and thermal design - for example, at 2 A, the HS2G dissipates up to 2.6 W resistively, requiring appropriate PCB copper area to maintain safe junction temperatures.

Does HS2G have a specified junction capacitance (C_J) value, and under what conditions?

Yes, the HS2G has a typical junction capacitance (C_J) of 50 pF, measured at 1 MHz frequency and 4.0 V reverse bias, as explicitly stated in the "ELECTRICAL SPECIFICATIONS" section. This parameter is essential for high-frequency noise analysis and snubber design in fast-switching topologies such as QR flyback converters where the HS2G is commonly deployed.

What is the reverse recovery time (t_rr) of HS2G, and how is it tested?

The HS2G has a maximum reverse recovery time (t_rr) of 50 ns, measured under conditions of 0.5 A forward current, 1.0 A reverse current, and 0.25 A reverse recovery current (I_rr), per the datasheet test definition. This fast recovery behavior enables efficient operation in high-frequency power supplies and reduces switching losses compared to standard recovery rectifiers.

What package type does HS2G use, and what are its key mechanical attributes?

The HS2G uses the DO-214AA (SMB) surface-mount package, featuring matte tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and a cathode band for polarity identification. Its 0.090 g weight and standardized SMB footprint support automated placement and reflow in high-volume manufacturing of compact power supplies using the HS2G.
