Product details
Overview
HS1GLW RVG 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 typical forward voltage at 1 A and 50 ns reverse recovery time, used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the HS1GLW RVG datasheet, HS1GLW RVG pinout, HS1GLW RVG application, or HS1GLW RVG equivalent, key selection criteria include VRRM = 400 V, IF = 1 A, trr = 50 ns, VF ≤ 1.3 V, and thermal resistance RθJA = 80 °C/W under standard PCB mounting conditions.
Technical Context
The HS1GLW RVG is a single-die, glass-passivated, low-profile surface-mount rectifier optimized for high-efficiency switching applications. Its 400 V VRRM, 30 A IFSM, and 175 °C maximum junction temperature support robust operation in compact power stages.
With 25 °C/W junction-to-lead thermal resistance and 16 pF junction capacitance at 1 MHz/4 V, the device enables fast switching with minimal capacitive loading and efficient heat transfer to the PCB pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - supports input rectification up to 400 V DC or 280 V RMS AC without breakdown |
| IF | 1 A continuous - rated for sustained conduction in low-power SMPS output stages |
| trr | 50 ns - enables high-frequency switching (>100 kHz) with reduced switching loss and EMI |
| VF | ≤1.3 V at 1 A, 25°C - limits conduction loss to ≤1.3 W per diode in series-pass configurations |
| RθJA | 80 °C/W - requires minimum 25 mm² copper pour for safe operation at full current in still air |
| Junction temp | –55°C to +175°C - suitable for automotive under-hood and industrial ambient environments |
| CJ | 16 pF at 1 MHz, 4 V - minimizes capacitive coupling in high-dv/dt gate-drive or snubber circuits |

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 | VRRM = 400 V, IF = 1 A, trr = 50 ns, but in DO-41 through-hole package | Requires through-hole assembly and larger board area; not suitable for automated SMT lines | Select when legacy through-hole compatibility or higher surge margin (IFSM = 35 A) is prioritized over size |
| Vishay VS-1EWH04-M3/5AT | VRRM = 400 V, IF = 1 A, trr = 50 ns, SOD-123W package, but VF = 1.25 V typ (25°C) | Nearly identical footprint and electrical specs; slightly lower forward drop improves light-load efficiency | Prefer for new designs targeting lowest possible conduction loss where sourcing flexibility is required |
Compared with MUR140 and VS-1EWH04-M3/5AT, the HS1GLW RVG offers identical VRRM/IF/trr performance in SOD-123W, with verified J-STD-020 Level 1 moisture rating and halogen-free compliance - making it optimal for high-volume, lead-free SMT production.

FAQ
What is the maximum junction temperature rating for HS1GLW RVG?
The HS1GLW RVG has a maximum junction temperature (TJMAX) of +175°C, allowing reliable operation in high-ambient environments such as enclosed industrial power supplies or automotive under-hood applications. This rating is validated per JEDEC test conditions and supports derating curves up to 175°C with appropriate PCB copper area. The HS1GLW RVG must be mounted on thermally adequate pads to maintain this limit under full 1 A load.
Does HS1GLW RVG meet RoHS and halogen-free requirements?
Yes, the HS1GLW RVG is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound, plating, and internal materials have been certified to contain no brominated flame retardants, chlorine, or fluorine above threshold limits. This makes the HS1GLW RVG suitable for export to EU, Japan, and other regulated markets requiring strict environmental compliance.
What is the reverse recovery time (trr) specification for HS1GLW RVG?
The HS1GLW RVG has a maximum reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery enables use in high-frequency switching topologies (e.g., 100–500 kHz) with reduced switching loss and EMI generation. The HS1GLW RVG achieves this performance via optimized silicon doping and glass passivation.
Is HS1GLW RVG suitable for automated SMT placement?
Yes, the HS1GLW RVG is explicitly designed for automated placement, with SOD-123W package geometry, matte tin-plated leads compliant with J-STD-002, and moisture sensitivity level 1 per J-STD-020 - eliminating pre-bake requirements. Its low profile and standardized tape-and-reel packaging (10,000 units per reel) ensure compatibility with high-speed pick-and-place systems.
What is the forward voltage (VF) of HS1GLW RVG at rated current?
The HS1GLW RVG exhibits a maximum forward voltage (VF) of 1.3 V at IF = 1 A and TJ = 25°C, with pulse testing (PW = 0.3 ms). At elevated temperatures (e.g., 125°C), VF decreases slightly due to negative temperature coefficient. This VF value directly determines conduction loss in the HS1GLW RVG, enabling accurate thermal modeling in power stage design.
