Product details
Overview
HSGLW from Taiwan Semiconductor is a 400 V, 0.8 A surface-mount high-efficiency rectifier diode in SOD-123W package, featuring glass-passivated junction, 50 ns reverse recovery time, and 0.91 V typical forward voltage at 0.8 A and 25°C - used in DC-DC converters and switching-mode inverters.
For engineers reviewing the HSGLW datasheet, HSGLW pinout, HSGLW application, or HSGLW equivalent, key selection factors include its 400 V repetitive peak reverse voltage, low-profile SOD-123W footprint, moisture sensitivity level 1 compliance, RoHS/halogen-free status, and thermal resistance of 34°C/W (junction-to-lead).
Technical Context
The HSGLW is a single-die, unidirectional silicon rectifier optimized for high-frequency switching applications. Its 50 ns reverse recovery time and 14 pF junction capacitance at 1 MHz / 4 V support efficient operation in SMPS and freewheeling paths where fast turn-off and low capacitive loading are critical.
Thermal performance is defined with reference to a 5 mm × 5 mm copper pad PCB test board: RθJL = 34°C/W and RθJA = 86°C/W. The device operates across –55°C to +150°C junction temperature range and supports surge current up to 20 A (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse voltage before breakdown; defines safe operating limit in flyback or boost converter output stages |
| IF | 0.8 A continuous forward current - steady-state conduction rating under thermal derating constraints |
| IFSM | 20 A peak surge current - withstands short-duration inrush or fault currents without failure |
| trr | 50 ns - enables high-frequency switching (>100 kHz) with minimal switching loss and EMI generation |
| CJ | 14 pF at 1 MHz, 4 V - low junction capacitance reduces capacitive coupling and improves noise immunity in high-speed circuits |
| VF | 0.91 V typ @ 0.8 A, 25°C - low forward drop minimizes conduction loss and thermal stress in power path |
| RθJL | 34°C/W - quantifies thermal path efficiency from junction to lead; enables accurate PCB copper pad sizing for thermal management |
Pinout & Package
Package: SOD-123W - low-profile, surface-mount plastic package with matte tin-plated leads, UL 94V-0 molding compound, polarity indicated by cathode band, and moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit (e.g., switch node in buck converter); requires adequate trace width for 0.8 A continuous current |
| Cathode | Forward current exit point | Marked by band; connects to output rail or return path; must be routed with minimal inductance in high-di/dt applications |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Enhances long-term reliability and humidity resistance in industrial environments without requiring conformal coating |
| Moisture sensitivity level 1 | Eliminates bake requirements prior to reflow; compatible with standard SMT assembly lines without dry-pack handling |
| RoHS and halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS directives; suitable for consumer and industrial products with strict environmental mandates |
| Low-profile SOD-123W package | Enables compact layout in space-constrained power modules and portable electronics; height ≤ 1.1 mm |
Applications
| DC–DC Converters | Switching Inverters |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 5–24 V outputs. IC Role / Device Role / Timing Role: Unidirectional current steering during transformer reset phase; conducts only when anode > cathode by ≥ VF. Use Value: 0.91 V forward drop at 0.8 A reduces conduction loss by ~15% vs. comparable 1.1 V diodes, improving efficiency at light-to-moderate loads. | Use Scenario: Output stage in single-phase H-bridge inverters for motor drives or UPS systems. IC Role / Device Role / Timing Role: Freewheeling path for inductive load current during PWM dead-time intervals. Use Value: 50 ns trr prevents shoot-through risk and limits voltage spikes during commutation, enhancing system robustness. |
| Freewheeling Diodes | AC–DC Adapters |
Use Scenario: Inductor current recirculation in buck regulators powering FPGAs or microcontrollers. IC Role / Device Role / Timing Role: Provides low-impedance return path when high-side switch turns off; clamps inductive kickback. Use Value: 34°C/W RθJL allows direct thermal coupling to PCB copper, enabling stable operation at 0.8 A without heatsink. | Use Scenario: Output rectification in compact wall adapters rated ≤ 15 W. IC Role / Device Role / Timing Role: Converts high-frequency transformer secondary AC to regulated DC; operates continuously at 100/120 kHz. Use Value: SOD-123W footprint and level-1 MSL rating simplify automated assembly and reduce BOM cost versus larger packages like DO-214AC. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R04 | Same VRRM (400 V), higher IF (1.0 A), slower trr (75 ns), TO-277 package | Higher thermal mass but larger footprint; less suitable for ultra-thin designs | Prefer HSGLW for space-constrained SMT layouts; STTH1R04 where higher surge margin or legacy TO-277 compatibility is needed |
| ES1D | Same VRRM (400 V), same IF (1.0 A), faster trr (35 ns), SOD-123 package (not SOD-123W) | Slightly smaller body and lower thermal resistance (RθJA ≈ 75°C/W), but no MSL-1 guarantee | Prefer HSGLW for production lines requiring MSL-1 compliance and J-STD-002 solderability; ES1D where speed is prioritized over assembly assurance |
Compared with STTH1R04 and ES1D, the HSGLW offers a balanced trade-off: MSL-1 process readiness, verified 50 ns recovery, and SOD-123W's optimized thermal pad area - making it preferred for high-volume, thermally constrained, and assembly-sensitive power supply designs.

FAQ
What is the repetitive peak reverse voltage rating of the HSGLW?
The HSGLW has a repetitive peak reverse voltage (VRRM) rating of 400 V. This value is explicitly specified in the Absolute Maximum Ratings table for the HSGLW variant and defines the maximum reverse-biased voltage the device can block repeatedly without breakdown. It is critical for selecting appropriate snubber components and verifying margin against transient overvoltage events in the target application.
Does the HSGLW have a defined reverse recovery time, and what is its value?
Yes, the HSGLW has a specified reverse recovery time (trr) of 50 ns maximum under conditions of IF = 0.5 A, IR = 1.0 A, and IRR = 0.25 A. This parameter is confirmed in the Electrical Specifications table and directly impacts switching loss and EMI in high-frequency topologies such as LLC resonant converters and synchronous rectifier control schemes using HSGLW.
What package type does the HSGLW use, and what are its key mechanical attributes?
The HSGLW uses the SOD-123W package - a low-profile, surface-mount outline with matte tin-plated leads compliant with J-STD-002, UL 94V-0 flammability rating, and moisture sensitivity level 1 per J-STD-020. Its polarity is marked by a cathode band, and typical weight is 0.016 g. These attributes ensure compatibility with high-speed pick-and-place equipment and standard reflow profiles without baking.
Is the HSGLW RoHS and halogen-free compliant?
Yes, the HSGLW is RoHS compliant and halogen-free in accordance with IEC 61249-2-21. This compliance is explicitly stated in the FEATURES section of the official documentation and verified through material declarations. It supports regulatory adherence for global commercial and industrial end products, including those sold in the EU and China.
What is the typical forward voltage of the HSGLW at 0.8 A and 25°C?
The typical forward voltage (VF) of the HSGLW is 0.91 V at 0.8 A and 25°C, as listed in the Electrical Specifications table. This value reflects actual measured performance under pulsed conditions (PW = 0.3 ms) and serves as a key input for conduction loss calculation in thermal modeling and efficiency estimation of power supply designs using HSGLW.
