Product details
Overview
HS1GLW from Taiwan Semiconductor is a 1 A, 400 V repetitive peak reverse voltage surface-mount silicon rectifier diode in SOD-123W package, featuring 1.3 V forward voltage at 1 A and 50 ns reverse recovery time, used in DC-DC converters and switching-mode inverters.
For engineers reviewing the HS1GLW datasheet, HS1GLW pinout, HS1GLW application, or HS1GLW equivalent, key selection criteria include its 400 V VRRM rating, 1.3 V VF at 1 A, 50 ns trr, SOD-123W low-profile package, and suitability for freewheeling and high-efficiency power conversion.
Technical Context
The HS1GLW is a single-die, glass-passivated silicon PN junction rectifier optimized for high-efficiency switching applications. Its 50 ns reverse recovery time and 1.3 V forward voltage reflect fast-switching capability with moderate conduction loss.
Thermally, it supports operation from –55°C to +175°C junction temperature, with RθJL = 25°C/W and RθJA = 80°C/W, enabling reliable performance in compact, thermally constrained PCB layouts.

Applications
| DC-DC Converter Output Rectification | Switching Mode Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 5–24 V at up to 1 A. IC Role / Device Role / Timing Role: Unidirectional current conduction path converting high-frequency AC from transformer secondary to regulated DC output. Use Value: 1.3 V VF and 50 ns trr reduce power loss and improve light-load efficiency over legacy 1N5819 or 1N4007 alternatives. | Use Scenario: Freewheeling path across inductive loads (e.g., motor windings, solenoids) in half-bridge inverters operating at 20–200 kHz. IC Role / Device Role / Timing Role: Provides low-loss return path for inductive current during switch-off phase, suppressing voltage spikes. Use Value: Fast 50 ns recovery prevents cross-conduction risk and limits dv/dt-induced gate stress on MOSFETs/IGBTs. |
| AC-DC Adapter Auxiliary Supply | Industrial Sensor Power Rail Clamping |
Use Scenario: Auxiliary bias supply rectification in offline AC-DC adapters powering control ICs and optocouplers. IC Role / Device Role / Timing Role: Converts rectified AC waveform to stable low-current DC rail (e.g., 12 V @ 50 mA). Use Value: 400 V VRRM provides margin against line surges; SOD-123W footprint saves board space versus DO-214AC. | Use Scenario: Reverse-polarity and transient clamping on 24 V sensor input lines exposed to field wiring faults. IC Role / Device Role / Timing Role: Acts as bidirectional clamp when paired with another diode, limiting negative excursions and absorbing inductive kick. Use Value: 175 °C TJ max ensures robustness in hot enclosures; 1 µA IR at 25 °C minimizes leakage impact on precision analog front-ends. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR140 | 400 V VRRM, 1 A IF, 50 ns trr, but TO-220AC package (larger, through-hole) | Suitable for higher-power or heatsink-mounted designs; not SMT-compatible | Choose MUR140 only if thermal mass or manual assembly is required; HS1GLW preferred for automated SMT production. |
| Vishay VS-1N4937-M3/54 | 400 V VRRM, 1 A IF, 1.2 V VF, 200 ns trr, DO-41 package | Slower recovery increases switching loss in >50 kHz circuits; axial lead requires different layout | Select VS-1N4937-M3/54 only for cost-sensitive, low-frequency (<30 kHz), through-hole designs where size is not constrained. |
Compared with MUR140 and VS-1N4937-M3/54, the HS1GLW delivers identical 400 V/1 A ratings with superior 50 ns speed and SOD-123W space savings-making it optimal for modern high-density, high-frequency SMT power supplies.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS1GLW?
The HS1GLW has a VRRM rating of 400 V, meaning it can reliably block up to 400 V of reverse voltage in repetitive operation without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version C2103) and is specific to the HS1GLW variant-not shared across the full HS1xLW series.
What is the forward voltage (VF) of HS1GLW at 1 A and 25°C?
The forward voltage of HS1GLW is 1.3 V at 1 A forward current and 25°C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents typical conduction loss in continuous operation when thermally managed.
Is HS1GLW compatible with lead-free reflow soldering processes?
Yes, HS1GLW is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its moisture sensitivity level is rated J-STD-020 Level 1-meaning it can be placed directly into reflow without baking, even after extended ambient storage.
What is the reverse recovery time (trr) specification for HS1GLW?
The reverse recovery time (trr) for HS1GLW is 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery enables efficient operation in switching power supplies operating above 100 kHz, reducing switching losses and EMI generation compared to slower general-purpose rectifiers.
Which package does HS1GLW use, and what are its key mechanical attributes?
HS1GLW uses the SOD-123W package: a low-profile, surface-mount plastic case with UL 94V-0 flammability rating, matte tin-plated leads, and cathode polarity marked by a band. It weighs approximately 0.016 g and supports automated placement per industry standards.
