Product details
Overview
ES1GLW RVG from Taiwan Semiconductor is a 1A, 400V super fast surface-mount rectifier in SOD-123W package, featuring 35ns reverse recovery time, 1.30V max forward voltage at 1A/25°C, and 30A peak surge current - deployed in DC-DC converters and switching-mode inverters for high-efficiency power conversion.
For engineers reviewing the ES1GLW RVG datasheet, ES1GLW RVG pinout, ES1GLW RVG application, or ES1GLW RVG equivalent, key selection criteria include VRRM = 400V, IF = 1A, trr = 35ns, thermal resistance RθJA = 80°C/W, and SOD-123W low-profile packaging for space-constrained board layouts.
Technical Context
This single-die, glass-passivated super fast rectifier delivers rapid switching with minimal stored charge, enabling reduced switching losses in high-frequency SMPS topologies. Its 175°C maximum junction temperature and J-STD-020 Level 1 moisture sensitivity support reflow-compatible automated assembly without preconditioning.
The device operates with low forward voltage (1.30V max at 1A/25°C) and ultra-low leakage (5µA max at 25°C, 100µA at 125°C), making it suitable for energy-sensitive applications where conduction loss and thermal runaway risk must be tightly controlled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - blocks up to 400V repetitive reverse voltage, matching mid-range industrial DC bus and flyback clamp requirements |
| IF | 1 A continuous - supports steady-state output rectification in sub-10W to 25W isolated converters |
| trr | 35 ns - enables operation up to ~3 MHz switching frequency before reverse recovery losses dominate |
| VF (max) | 1.30 V @ 1A, 25°C - contributes ≤1.3W conduction loss at full load, easing thermal design in sealed enclosures |
| RθJA | 80 °C/W - requires ≥25 mm² copper pour for safe 1A operation at 70°C ambient without derating |
| IFSM | 30 A (8.3ms half-sine) - withstands cold-start inrush and transient overloads in offline adapters |
Pinout & Package
SOD-123W surface-mount package: 2-terminal, cathode-indicated by band; matte tin-plated leads; UL 94V-0 molding compound; 0.016g weight; polarity-critical for series/parallel stacking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current entry point | Connected to transformer secondary or switch node; must handle full forward surge current (30A) |
| Cathode | Output current exit point | Marked by band; ties to output capacitor or filter choke; defines reference for voltage drop measurement |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable long-term reliability under thermal cycling and humidity exposure per J-STD-020 Level 1 |
| Low profile SOD-123W | 0.9mm max height allows placement under connectors or near heat sinks in ultra-thin power modules |

| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for global industrial and consumer shipments |
Applications
| DC-DC Converter | Switching Inverter |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated 12V–24V input buck-derived DC-DC modules for telecom shelf power. IC Role / Device Role / Timing Role: Freewheeling diode conducting during high-side MOSFET off-time; critical for minimizing conduction loss and maintaining regulation. Use Value: 1.30V VF and 35ns trr reduce average power loss by 0.8W vs. legacy FR107, extending thermal margin in 12mm × 12mm modules. | Use Scenario: Output rectification in 400V DC-link inverters for HVAC variable-speed drives and solar microinverters. IC Role / Device Role / Timing Role: Unidirectional current path converting high-frequency AC from H-bridge into filtered DC; handles 30A surge during motor startup. Use Value: 400V VRRM and 175°C TJMAX ensure robustness across 300–450V DC bus transients without derating. |
| Freewheeling Diode | SMPS Flyback Clamp |
Use Scenario: Inductive load snubbing in automotive body control modules driving solenoids, relays, and fuel injectors. IC Role / Device Role / Timing Role: Provides low-loss return path for coil energy when driver switches off; must respond within nanoseconds to prevent voltage spikes. Use Value: 35ns trr limits clamping overshoot to <15% above supply rail, eliminating need for TVS supplementation in 24V systems. | Use Scenario: RCD clamp network in 65kHz flyback converters powering industrial sensors and PLC I/O modules. IC Role / Device Role / Timing Role: Absorbs leakage inductance energy during primary switch turn-off; must recover before next cycle to avoid cumulative voltage stress. Use Value: Fast recovery prevents reverse conduction overlap with primary switch, reducing clamp dissipation by 30% versus 100ns alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | VRRM = 600V, trr = 30ns, VF = 1.35V @ 1A - higher blocking, slightly faster, but 0.05V higher forward drop | Better suited for 400–600V DC bus designs requiring margin; less optimal for 200–300V systems due to excess voltage rating | Select when system-level VR exceeds 450V or when <30ns trr is required for >1MHz operation |
| ON Semi MUR120E | VRRM = 200V, trr = 35ns, VF = 1.05V @ 1A - lower voltage rating, lower VF, same speed | Optimized for 100–150V output stages (e.g., PoE PSE, USB PD); insufficient for 400V bus applications | Choose only for 200V-class designs where lower conduction loss outweighs voltage margin needs |
Compared with STTH1L06S and MUR120E, ES1GLW RVG uniquely balances 400V blocking, 1.30V VF, and 35ns trr in SOD-123W - offering optimal thermal density and layout compatibility for 24–48V input, 300–400V output SMPS where voltage rating and footprint are co-constrained.

FAQ
What is the maximum junction temperature rating for ES1GLW RVG?
The ES1GLW RVG has a maximum junction temperature (TJMAX) of +175°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version C2103. This rating allows reliable operation in high-ambient environments such as enclosed power supplies or under heatsink-limited conditions. Derating begins above 70°C ambient, and the device maintains full 1A current capability up to 125°C case temperature when mounted on ≥25 mm² copper.
Does ES1GLW RVG have a RoHS-compliant and halogen-free construction?
Yes, ES1GLW RVG is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002 solderability standards. These attributes are confirmed in the mechanical data and compliance sections of the Taiwan Semiconductor ES1DLW–ES1JLW datasheet (Version C2103).
What is the reverse recovery time (trr) specification for ES1GLW RVG, and under what test conditions?
The reverse recovery time (trr) for ES1GLW RVG is 35 ns maximum, measured under conditions of IF = 0.5 A, IR = 1.0 A, and IRR = 0.25 A, as specified in the Electrical Specifications table of the Taiwan Semiconductor datasheet. This value reflects performance at 25°C ambient and is critical for minimizing switching loss in high-frequency converters operating above 300 kHz.
Is ES1GLW RVG pin-compatible with other devices in the ES1xLW family?
Yes, ES1GLW RVG shares identical SOD-123W package dimensions, pinout, and thermal pad layout with ES1DLW and ES1JLW. All variants use the same anode/cathode terminal configuration and cathode band marking. However, voltage ratings differ: ES1DLW = 200V, ES1GLW = 400V, ES1JLW = 600V - so substitution requires verification of system-level reverse voltage stress.
What is the typical junction-to-ambient thermal resistance (RθJA) for ES1GLW RVG?
The typical junction-to-ambient thermal resistance (RθJA) for ES1GLW RVG is 80°C/W, as published in the Thermal Performance section of the Taiwan Semiconductor datasheet. This value assumes standard JEDEC 2-layer board conditions (1 in² copper). With ≥25 mm² of 2-oz copper connected to both terminals, RθJA improves to ~55°C/W, enabling full 1A operation at 70°C ambient without forced airflow.
