Product details
Overview
HS1GFSH from Taiwan Semiconductor is a 1A, 400V glass-passivated surface-mount fast rectifier in SOD-128 package, featuring 0.91V forward voltage at 1.0A/25°C, 50ns reverse recovery time, and AEC-Q101 qualification for automotive power conversion.
For engineers reviewing the HS1GFSH datasheet, HS1GFSH pinout, HS1GFSH application, or HS1GFSH equivalent, key selection criteria include its 400V VRRM, low-profile SOD-128 thermal performance (RθJL = 29°C/W), junction temperature range (–55°C to +150°C), and suitability for high-efficiency DC/DC converters requiring fast switching and low conduction loss.
Technical Context
This device implements a single-die silicon PN junction rectifier with glass passivation for enhanced reliability and moisture resistance (MSL Level 1). Its fast recovery (50ns) and low forward voltage support high-frequency operation in switching power supplies.
The SOD-128 package enables automated placement and provides robust thermal dissipation via copper pad mounting, with RθJA = 51°C/W on a 5mm × 5mm Cu pad - critical for thermally constrained automotive and industrial PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse voltage; defines safe blocking capability in 400V-rated power rails |
| IF | 1 A - continuous forward current rating; supports sustained 1A load in compact SOD-128 footprint |
| VF @ 1A, 25°C | 0.91 V (typ), 1.30 V (max) - low conduction loss enabling >92% efficiency in 12V→5V DC/DC stages |
| trr | 50 ns - fast reverse recovery minimizes switching loss and EMI in 100–500 kHz converters |
| RθJL | 29 °C/W - junction-to-lead thermal resistance enables direct heat transfer to PCB copper, reducing thermal derating |
| Junction Temp Range | –55°C to +150°C - validated for under-hood automotive environments and industrial ambient extremes |
| CJ @ 1MHz, 4V | 17 pF - low junction capacitance reduces capacitive turn-on loss and improves high-frequency rectification fidelity |
Pinout & Package
SOD-128 is a low-profile, surface-mount plastic package with two terminals: anode and cathode. Polarity is marked by a visible cathode band on the device body. The package meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/source side of rectifier path; requires adequate trace width for 1A continuous current |
| Cathode | Forward current exit / reverse voltage reference | Marked by band; ties to output/load side; serves as reference node for snubber and freewheeling paths |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power electronics per stress test requirements (HTOL, TC, HAST, etc.) |
| Glass passivated junction | Prevents moisture ingress and metallization corrosion, extending lifetime in humid environments |
| Low profile SOD-128 | Height ≤ 1.1 mm enables use in space-constrained modules and stacked PCB assemblies |
| Fast switching (50 ns trr) | Reduces switching losses and diode ringing in synchronous and quasi-resonant topologies |
| Matte tin-plated leads | Ensures reliable solder wetting and compatibility with lead-free reflow profiles (J-STD-002) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L04S | Same 400V VRRM, but 1.05V VF @ 1A/25°C and 60ns trr; TO-277 package (larger footprint) | Higher forward drop increases conduction loss; larger package limits board density | Preferred where legacy TO-277 layout exists or higher surge rating (IFSM = 50A) is required |
| ON Semi MUR1040 | 400V VRRM, 1.25V VF @ 1A/25°C, 60ns trr; DO-41 through-hole package | Through-hole mounting incompatible with automated SMT lines; higher VF degrades efficiency | Only suitable for prototyping or legacy through-hole designs; not recommended for new SMT automotive designs |
Compared with STTH1L04S and MUR1040, HS1GFSH delivers lower forward voltage and faster recovery in a smaller, AEC-Q101-qualified SOD-128 package - making it optimal for space- and efficiency-critical automotive DC/DC converters.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS1GFSH?
The HS1GFSH has a VRRM of 400 V, meaning it can reliably block up to 400 volts of reverse voltage in repetitive applications without breakdown. This rating is verified per JEDEC test conditions and aligns with its marking code "HS1G" (G = 400V). Exceeding this voltage risks avalanche failure or permanent damage to the HS1GFSH junction.
Is HS1GFSH suitable for automotive applications?
Yes, HS1GFSH is AEC-Q101 qualified and tested for automotive-grade reliability, including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. Its –55°C to +150°C junction temperature range and glass-passivated die make it appropriate for under-hood and cabin-mounted power systems using HS1GFSH.
What is the forward voltage (VF) of HS1GFSH at 1.0A and 25°C?
The typical forward voltage of HS1GFSH at 1.0A and 25°C is 0.91 V, with a maximum specification of 1.30 V. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects low conduction loss critical for efficiency in 1A DC/DC output stages using HS1GFSH.
Does HS1GFSH have a defined reverse recovery time (trr)?
Yes, HS1GFSH has a specified reverse recovery time of 50 ns maximum, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast trr enables efficient operation in high-frequency switching circuits and reduces switching losses compared to standard recovery rectifiers.
What package type does HS1GFSH use, and what are its key mechanical features?
HS1GFSH uses the SOD-128 surface-mount package: low-profile (≤1.1 mm height), matte tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and polarity indicated by a cathode band. Its thermal design supports RθJL = 29°C/W when mounted on a 5 mm × 5 mm copper pad - a key feature of the HS1GFSH construction.
