Product details
Overview
RS1DL from Taiwan Semiconductor is a fast recovery surface-mount rectifier diode rated for 200 V repetitive peak reverse voltage (VRRM), 0.8 A average forward current (IF), and 30 A non-repetitive surge current (IFSM), used in DC-DC converters and switching-mode power supplies where compact size and fast switching are required.
For engineers reviewing the RS1DL datasheet, RS1DL pinout, RS1DL application, or RS1DL equivalent, key selection criteria include its 200 V VRRM rating, sub-SMA package compatibility with automated placement, 150 ns reverse recovery time (trr), 1.3 V max forward voltage at 0.8 A, and moisture sensitivity level 1 compliance per J-STD-020.
Technical Context
The RS1DL is a single-die, glass-passivated silicon junction rectifier optimized for high-frequency switching applications. Its 150 ns reverse recovery time enables efficient operation in SMPS topologies up to several hundred kHz, while its 32 °C/W junction-to-lead thermal resistance supports reliable power dissipation under continuous 0.8 A conduction.
Designed for surface-mount assembly on standard PCBs, the RS1DL features matte tin-plated leads compliant with J-STD-002 solderability and meets UL 94V-0 flammability requirements in its sub-SMA molded case. Polarity is indicated by a cathode band, and the device operates across a -55°C to +150°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage the device blocks without breakdown; defines usable input voltage range in bridge or flyback configurations. |
| IF | 0.8 A - Continuous average forward current at TA = 25°C; determines maximum steady-state output capability in low-power DC-DC stages. |
| IFSM | 30 A - Peak non-repetitive surge current (8.3 ms half-sine); supports inrush current handling during startup or transient overload. |
| trr | 150 ns - Reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25A; enables high-frequency switching with reduced switching losses. |
| VF (max) | 1.3 V - Forward voltage drop at IF = 0.8 A and TJ = 25°C; directly impacts conduction loss and thermal design in compact layouts. |
| RθJL | 32 °C/W - Junction-to-lead thermal resistance; allows direct heatsinking via PCB copper pour or thermal pad for improved reliability. |
Pinout & Package
Package: Sub-SMA - Surface-mount plastic package with gull-wing leads, UL 94V-0 rated molding compound, and cathode polarity marked by a visible band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit (e.g., transformer secondary or switch node return path). |
| Cathode | Forward current exit point | Marked by band; connects to output rail or filter capacitor positive terminal; defines direction of rectified current flow. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enhances long-term reliability and humidity resistance in industrial environments without requiring conformal coating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R02 | 100 V VRRM, 1 A IF, 125 ns trr, DO-214AC package | Limited to ≤100 V circuits; higher current rating but lower voltage margin than RS1DL | Select when 100 V blocking suffices and higher IF headroom is needed. |
| ES1D | 200 V VRRM, 1 A IF, 35 ns trr, SMA package | Faster recovery and higher IF, but SMA (not sub-SMA) footprint requires layout change | Choose for ultra-low-loss designs where 35 ns trr justifies rework of pad layout. |
Compared with STTH1R02 and ES1D, the RS1DL offers balanced 200 V/0.8 A performance in the smaller sub-SMA outline, making it optimal for space-constrained 24–48 V industrial converters where 150 ns trr delivers sufficient efficiency without demanding ultra-fast switching.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for RS1DL?
The RS1DL has a VRRM rating of 200 V, meaning it reliably blocks reverse voltages up to this level without breakdown under repetitive conditions. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version N2103) and defines the upper limit for input or clamping voltage in circuits using RS1DL.
What is the reverse recovery time (trr) specification for RS1DL, and under what test conditions is it measured?
The RS1DL has a maximum reverse recovery time (trr) of 150 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is specified in the Electrical Specifications section of the Taiwan Semiconductor RS1AL–RS1ML datasheet and reflects its suitability for high-frequency switching applications such as 200–500 kHz DC–DC converters.
Is RS1DL compatible with lead-free reflow soldering processes?
Yes, RS1DL is compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its moisture sensitivity level is rated at Level 1 per J-STD-020 - meaning no baking is required prior to assembly, supporting standard Pb-free reflow profiles without risk of popcorning or delamination.
What package type does RS1DL use, and how does it differ from standard SMA?
RS1DL uses the sub-SMA package - a dimensionally reduced variant of the SMA outline with tighter lead spacing and lower profile. Unlike standard SMA, sub-SMA enables higher board density and is optimized for fine-pitch automated placement. The marking diagram and package outline dimensions in the Taiwan Semiconductor datasheet confirm this distinction for RS1DL.
Does RS1DL have halogen-free and RoHS-compliant construction?
Yes, RS1DL is both RoHS compliant and halogen-free in accordance with IEC 61249-2-21. These environmental attributes are explicitly stated in the Features section of the Taiwan Semiconductor RS1AL–RS1ML datasheet (Version N2103) and verified through material declarations supporting compliance for global market access.
