Product details
Overview
RS2KA from Taiwan Semiconductor is a 1.5A, 800V fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 500 ns reverse recovery time, 1.3 V max forward voltage at 1.5 A, and 5 µA max reverse leakage at 25°C - used in snubber networks and DC-DC converters requiring high-voltage transient handling.
For engineers reviewing the RS2KA datasheet, RS2KA pinout, RS2KA application, or RS2KA equivalent, key selection criteria include its 800 V repetitive peak reverse voltage, 50 A surge rating, 175°C junction temperature limit, thermal resistance of 18°C/W (junction-to-lead), and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
This single-die fast recovery rectifier uses glass-passivated junction technology to achieve stable switching performance under repetitive surge conditions. Its 500 ns trr and low 50 pF junction capacitance support efficient operation in high-frequency switching topologies up to several hundred kHz.
The device operates across –55°C to +175°C junction range with JESD201 Class 2 whisker resistance and moisture sensitivity level 1. Thermal design leverages 18°C/W RθJL for direct lead heat conduction and 55°C/W RθJA for board-level dissipation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L80 | Same 1.5 A / 800 V rating; 350 ns trr, 1.25 V VF max - faster but lower surge rating (30 A) | Better for higher-frequency (>300 kHz) topologies where lower trr reduces switching loss | Prefer STTH1L80 when optimizing for speed over surge robustness |
| ON Semi MUR180 | 1.5 A / 800 V; 75 ns trr, 1.7 V VF max - ultrafast but higher conduction loss | Suitable for resonant LLC and PFC boost diodes where low trr dominates efficiency | Choose MUR180 only if system prioritizes reverse recovery over forward drop |
Compared with STTH1L80 and MUR180, RS2KA trades slightly slower recovery (500 ns) for superior surge capability (50 A vs. 30 A/30 A) and lower forward voltage than ultrafast types - making it optimal for cost-sensitive, ruggedized industrial SMPS where reliability under overload is critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for RS2KA?
The RS2KA has a VRRM of 800 V, verified per Taiwan Semiconductor's official datasheet revision I2304. This rating defines the highest instantaneous reverse voltage the device can block repeatedly without breakdown. It supports use in 400–600 V DC bus applications and ensures margin against voltage transients in offline SMPS designs. The RS2KA's 800 V rating places it between RS2JA (600 V) and RS2MA (1000 V) in the RS2x family.
What is the reverse recovery time (trr) specification for RS2KA?
The RS2KA has a maximum reverse recovery time of 500 ns under specified test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A). This value is confirmed in the Electrical Specifications table on page 2 of the RS2AA–RS2MA datasheet (I2304). It reflects the device's suitability for switching frequencies up to ~300 kHz in hard-switched topologies, balancing speed and robustness.
Is RS2KA RoHS and halogen-free compliant?
Yes, RS2KA is explicitly stated as RoHS compliant and halogen-free in the FEATURES section of the official datasheet. The molding compound meets UL 94V-0, and terminals are matte tin plated per J-STD-002. These attributes are validated for all RS2x variants including RS2KA, supporting compliance in industrial and lighting applications subject to environmental regulations.
What package type does RS2KA use, and what are its key mechanical properties?
RS2KA uses the DO-214AC (SMA) surface-mount package. Key mechanical properties include a 0.060 g weight, J-STD-020 moisture sensitivity level 1 (no bake required), JESD201 Class 2 whisker resistance, and polarity indicated by a cathode band. Dimensions match JEDEC DO-214AC standards, with suggested pad layout provided in the datasheet's Package Outline Dimensions section.
What is the maximum forward voltage (VF) for RS2KA at rated current?
The RS2KA has a maximum forward voltage of 1.3 V at IF = 1.5 A and TJ = 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At elevated temperatures or higher currents, VF increases predictably per the Typical Forward Characteristics curve, remaining below 1.5 V up to 175°C junction temperature.
