Product details
Overview
RS2KAHR3G 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. It serves as a primary output rectifier in high-frequency switching power supplies.
For engineers reviewing the RS2KAHR3G datasheet, RS2KAHR3G pinout, RS2KAHR3G application, or RS2KAHR3G equivalent, key selection criteria include repetitive peak reverse voltage (800 V), thermal resistance (18 °C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and suitability for automated SMT assembly.
Technical Context
This device is a single-die, glass-passivated silicon PN junction rectifier optimized for fast switching in DC–DC converters and SMPS topologies. Its 500 ns trr enables efficient operation at frequencies up to several hundred kHz while maintaining low conduction loss via 1.3 V VF and robust surge capability (50 A IFSM).
The DO-214AC (SMA) package provides standardized SMT compatibility with matte tin-plated leads, UL 94V-0 molding compound, and JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band; weight is 0.060 g.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Withstands repetitive reverse voltage up to 800 V without breakdown, enabling use in 400 V AC-input SMPS outputs. |
| IF | 1.5 A continuous - Supports average forward current up to 1.5 A at TA = 75°C with derating per curve Fig.1. |
| trr | 500 ns - Fast recovery minimizes switching losses and EMI in high-frequency converters (>100 kHz). |
| VF | ≤1.3 V @ 1.5 A, 25°C - Low forward drop reduces conduction loss and improves system efficiency. |
| IR | ≤5 µA @ 800 V, 25°C - Low leakage preserves efficiency in high-impedance snubber or hold-up circuits. |
| RθJL | 18 °C/W - Enables direct thermal path to PCB copper, supporting compact heatsinking in space-constrained designs. |
Pinout & Package
DO-214AC (SMA) surface-mount package with axial lead configuration: anode and cathode terminals formed by molded plastic body ends; polarity indicated by cathode band on cathode end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., transformer secondary center-tap or switch node); must handle 1.5 A continuous and 50 A surge. |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail; cathode band marks this terminal for unambiguous PCB layout and assembly orientation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enhances long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in industrial environments. |
| J-STD-020 Level 1 moisture sensitivity | Allows unlimited floor life before reflow; no baking required prior to standard SMT assembly. |
| RoHS and halogen-free compliance | Meets global environmental regulations (EU RoHS Directive 2011/65/EU, IEC 61249-2-21) for consumer and industrial end equipment. |
| UL 94V-0 molded compound | Provides flame-retardant housing essential for safety-critical power supply designs certified to UL/EN 62368-1. |
Applications
| DC–DC Converter Output Rectification | Snubber Network Diode |
|---|---|
Use Scenario: Used as secondary-side rectifier in isolated flyback or forward converters delivering 12–48 V output at ≤1.5 A. IC Role / Device Role / Timing Role: Unidirectional current valve converting high-frequency AC from transformer secondary into regulated DC output. Use Value: 500 ns trr and 1.3 V VF minimize switching and conduction losses, improving overall converter efficiency by ≥0.8% vs. standard recovery diodes. | Use Scenario: Placed across MOSFET drain-source or transformer primary to clamp voltage spikes during switching transitions. IC Role / Device Role / Timing Role: Fast-recovery clamping diode absorbing inductive energy and limiting dv/dt stress on switching devices. Use Value: 800 V VRRM withstands transient overvoltages; 500 ns trr ensures rapid turn-off before next switching edge, preventing snap-off oscillation. |
| LED Driver Secondary Rectification | Industrial Power Supply Input Bridge Leg |

IC Role / Device Role / Timing Role: Half-wave rectifying element in discrete bridge configuration, handling line-frequency and harmonic currents. Use Value: 50 A IFSM rating accommodates cold-start inrush surges; 5 µA IR at 25°C maintains low standby power in always-on systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 1 A IF, 600 V VRRM, 150 ns trr, TO-277 package | Lower voltage rating and faster recovery; suited for <600 V, higher-frequency designs | Select when system peak reverse voltage ≤600 V and trr <200 ns is required; not suitable for 800 V applications. |
| ON Semi MUR160 | 1 A IF, 600 V VRRM, 75 ns trr, DO-41 package | Through-hole, faster recovery, lower current; requires manual or wave soldering | Choose for legacy through-hole designs or where ultra-fast recovery dominates over current rating and SMT compatibility. |
Compared with STTH1L06S and MUR160, RS2KAHR3G offers higher voltage capability (800 V) and SMT-ready DO-214AC packaging-critical for modern compact, automated power supply designs-while trading off some speed for robustness in 1.5 A continuous operation.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for RS2KAHR3G?
The RS2KAHR3G has a VRRM rating of 800 V, meaning it can reliably block reverse voltages up to 800 V in repetitive operation without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version I2304), and aligns with the "KA" suffix in the marking code. Designers must ensure circuit peak reverse transients remain below this limit with appropriate safety margin.
Does RS2KAHR3G support lead-free reflow soldering per JEDEC J-STD-020?
Yes, RS2KAHR3G is rated J-STD-020 Level 1 for moisture sensitivity, permitting unlimited floor life and compatibility with standard lead-free reflow profiles (peak temperature ≤260°C). Its matte tin-plated leads meet J-STD-002 solderability requirements, and the UL 94V-0 molding compound withstands multiple reflow cycles without delamination or cracking.
What is the reverse recovery time (trr) of RS2KAHR3G, and under what test conditions is it specified?
The RS2KAHR3G has a maximum reverse recovery time (trr) of 500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the Electrical Specifications table. This value applies to both RS2KA and RS2MA variants and reflects performance at room temperature; trr increases moderately at elevated junction temperatures but remains within fast-recovery classification.
Is RS2KAHR3G halogen-free and RoHS compliant?
Yes, RS2KAHR3G is explicitly stated as RoHS compliant and halogen-free in the FEATURES section of the TSC datasheet. It meets EU Directive 2011/65/EU and IEC 61249-2-21 requirements, with bromine and chlorine content below 900 ppm each and total halogens ≤1500 ppm-verified by material declarations and third-party testing.
What package type does RS2KAHR3G use, and what are its key mechanical attributes?
RS2KAHR3G uses the DO-214AC (SMA) surface-mount package. Key mechanical attributes include UL 94V-0 flammability-rated molding compound, JESD201 Class 2 whisker-resistant matte tin plating, cathode band polarity marking, and a typical weight of 0.060 g. Dimensions match JEDEC DO-214AC Issue D, with recommended pad layout provided in the Package Outline Drawing.
