Product details

Overview

HS2GFSH from Taiwan Semiconductor is a 2 A, 400 V glass-passivated surface-mount fast recovery rectifier in SOD-128 package, featuring 0.99 V max forward voltage at 2 A and 25°C, 50 ns reverse recovery time, and AEC-Q101 qualification for automotive power conversion.

For engineers reviewing the HS2GFSH datasheet, HS2GFSH pinout, HS2GFSH application, or HS2GFSH equivalent, key selection criteria include repetitive peak reverse voltage (400 V), thermal resistance (R_θJL = 17 °C/W), junction temperature range (–55 to +150 °C), and low-profile SOD-128 mounting compatibility with automated assembly.

Technical Context

The HS2GFSH employs a single-die silicon PN junction with glass passivation for enhanced reliability and moisture resistance (MSL Level 1). Its fast recovery (trr ≤ 50 ns) and low forward voltage support high-frequency switching in DC/DC converters and snubber circuits.

Thermal performance is defined by R_θJL = 17 °C/W and R_θJA = 53 °C/W on a 5 mm × 5 mm Cu pad PCB, enabling sustained 2 A operation up to +125 °C ambient when properly heatsinked via lead termination.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or freewheeling topologies.
I_F	2 A - Continuous forward current rating; supports compact power stages without forced air cooling.
V_F (max)	1.30 V at 2 A, 25°C - Directly impacts conduction loss and thermal design in high-duty-cycle applications.
t_rr	50 ns - Enables efficient operation up to ~1 MHz switching frequencies with minimal switching loss.
R_θJL	17 °C/W - Low junction-to-lead thermal resistance allows effective heat transfer through PCB copper pads.
C_J	25 pF at 1 MHz, 4 V - Limits capacitive coupling noise in high dv/dt environments like motor drives.
I_R (max)	1 µA at 25°C - Ensures low leakage in high-impedance bias networks and precision sensing paths.

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; TO-277 package (larger footprint, higher R_θJA = 70 °C/W).	Less suitable for space-constrained automotive modules due to larger outline and thermal limitations.	Prefer HS2GFSH where board area or thermal performance on small pads is critical.
ES2D	2 A / 200 V rating; SOD-123 package; trr = 35 ns but lower V_RRM limits use to <200 V systems.	Not viable for 400 V bus applications such as 48 V mild-hybrid subsystems.	Select HS2GFSH when 400 V blocking and AEC-Q101 compliance are mandatory.

Compared with STTH2R04 and ES2D, the HS2GFSH uniquely combines AEC-Q101 qualification, SOD-128 low-profile packaging, 400 V blocking, and 50 ns recovery-making it optimal for automotive-grade, space-sensitive, medium-voltage rectification where thermal and reliability margins are constrained.

FAQ

What is the maximum junction temperature rating for HS2GFSH?

The HS2GFSH has a maximum junction temperature (T_J) of +150 °C and a minimum of –55 °C, per its Absolute Maximum Ratings table. This wide range supports operation in underhood automotive environments and industrial enclosures without active cooling. Derating curves confirm 2 A continuous current is sustainable up to +125 °C ambient when mounted on a 5 mm × 5 mm Cu pad, as specified in the Thermal Performance section of the HS2GFSH datasheet.

Is HS2GFSH suitable for use in AEC-Q101-compliant automotive designs?

Yes, the HS2GFSH is explicitly AEC-Q101 qualified, as stated in its FEATURES section and verified in Taiwan Semiconductor's official documentation. This qualification covers stress testing for temperature cycling, humidity bias, mechanical shock, and solderability-ensuring suitability for automotive powertrain, chassis, and body electronics. The HS2GFSH's MSL Level 1 rating and halogen-free construction further align with automotive manufacturing requirements.

What is the reverse recovery time (t_rr) of HS2GFSH and how is it measured?

The HS2GFSH has a reverse recovery time (t_rr) of ≤50 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, per the Electrical Specifications table. This value is confirmed across the full operating temperature range and enables efficient use in switching power supplies operating up to several hundred kHz. The fast t_rr directly reduces switching losses and EMI compared to standard recovery rectifiers.

Does HS2GFSH have a specified junction-to-case thermal resistance (R_θJC)?

Yes, the HS2GFSH specifies R_θJC = 21 °C/W in its Thermal Performance table. This parameter reflects heat transfer from junction to case surface and is measured using standardized test conditions. While R_θJL = 17 °C/W is more relevant for SOD-128's lead-mounted thermal path, R_θJC supports thermal modeling when using external heatsinking or conformal coating strategies in sealed automotive housings.

What packaging and reel quantity is offered for HS2GFSH?

The HS2GFSH is supplied in SOD-128 package on tape-and-reel format, with 14,000 units per reel, as documented in the Ordering Information section. The device features matte tin-plated leads compliant with J-STD-002 solderability standards and a cathode band for unambiguous polarity identification-critical for automated placement accuracy and post-solder inspection in high-volume automotive manufacturing.
