Product details
Overview
RS1GL from Taiwan Semiconductor is a fast recovery surface-mount rectifier diode with 400 V repetitive peak reverse voltage (VRRM), 0.8 A average forward current (IF), and 150 ns reverse recovery time (trr) measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A - used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the RS1GL datasheet, RS1GL pinout, RS1GL application, or RS1GL equivalent, key selection criteria include its Sub SMA package, 1.3 V max forward voltage at 0.8 A, 5 µA max reverse leakage at 25°C, 30 A non-repetitive surge rating, and thermal resistance of 32°C/W junction-to-lead.
Technical Context
The RS1GL is a single-die, glass-passivated, fast recovery rectifier optimized for high-frequency switching applications. Its 150 ns trr enables efficient operation in SMPS topologies where rapid turn-off minimizes switching losses and EMI generation.
It features a Sub SMA package with matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity is indicated by a cathode band, and the device operates across -55°C to +150°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking voltage; defines usable input voltage range in bridge or flyback configurations |
| IF | 0.8 A - continuous average forward current at TL = 75°C; determines steady-state power handling in rectification paths |
| trr | 150 ns - reverse recovery time under specified test conditions; directly impacts switching loss and frequency limit in hard-switched converters |
| VF max | 1.3 V @ 0.8 A, 25°C - forward voltage drop; sets conduction loss and thermal load at rated current |
| IR max | 5 µA @ 400 V, 25°C - reverse leakage current; affects standby power and high-impedance bias network integrity |
| RθJL | 32 °C/W - junction-to-lead thermal resistance; enables direct heatsinking via PCB copper and informs thermal design margin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R04 | 400 V VRRM, 1.0 A IF, 125 ns trr, DO-214AC package | Higher IF rating and faster trr, but larger footprint and 50°C/W RθJA | Preferred where higher current headroom or tighter switching timing is required; requires PCB layout revision |
| MBR0540 | 40 V VRRM, 0.5 A IF, Schottky architecture, 0.55 V VF | Lower VRRM and conduction loss, but unsuitable for 400 V line applications due to breakdown risk | Only viable in low-voltage DC-DC outputs (<28 V); not interchangeable in AC-input or high-VR circuits |
Compared with STTH1R04 and MBR0540, the RS1GL offers optimal balance of 400 V blocking, 0.8 A current, 150 ns speed, and Sub SMA thermal performance for cost-sensitive industrial SMPS designs where board space and thermal management are constrained.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for RS1GL?
The RS1GL has a VRRM of 400 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version N2103). This rating defines the highest reverse voltage the device can block repeatedly without breakdown and is essential for selecting appropriate input voltage margins in AC-DC and DC-DC designs. The RS1GL is part of the RS1AL–RS1ML series, where the letter 'G' explicitly corresponds to the 400 V variant.
What is the reverse recovery time (trr) specification for RS1GL and under what test conditions?
The RS1GL has a maximum reverse recovery time (trr) of 150 ns, measured under the conditions IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Electrical Specifications table in the Taiwan Semiconductor RS1AL–RS1ML datasheet. This value is specific to the RS1GL variant and differs from slower versions like RS1JL (250 ns) and RS1KL (500 ns), confirming its suitability for higher-frequency switching applications.
Does RS1GL have a Sub SMA package, and what are its key mechanical attributes?
Yes, the RS1GL uses the Sub SMA package, as stated in the Mechanical Data and Ordering Information sections of the Taiwan Semiconductor datasheet. Key attributes include UL 94V-0 flammability-rated molding compound, matte tin-plated gull-wing leads compliant with J-STD-002, JESD201 Class 2 whisker resistance, and cathode polarity indicated by a visible band. Its weight is approximately 0.019 g.
What is the maximum forward voltage (VF) for RS1GL and at what operating condition?
The RS1GL has a maximum forward voltage (VF) of 1.3 V at IF = 0.8 A and TJ = 25°C, per the Electrical Specifications table. This parameter directly determines conduction loss and junction temperature rise under load. The datasheet notes this is measured using a 0.3 ms pulse test, ensuring relevance to typical switching converter duty cycles.
Is RS1GL RoHS and halogen-free compliant?
Yes, the RS1GL is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor RS1AL–RS1ML datasheet (Version N2103). This compliance supports environmental requirements for industrial and commercial electronics sold in EU, China, and other regulated markets.
