Product details

Overview

RS2K R5G from Taiwan Semiconductor is a 2A, 800V fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 500 ns reverse recovery time, 1.3 V max forward voltage at 2A, and 5 µA max reverse leakage at 25°C. It serves as primary-side AC/DC input rectifier in compact offline SMPS for industrial power adapters.

For engineers reviewing the RS2K R5G datasheet, RS2K R5G pinout, RS2K R5G application, or RS2K R5G equivalent, key selection criteria include V_RRM = 800 V, I_F = 2 A continuous, t_rr = 500 ns, thermal resistance R_θJA = 55 °C/W, and DO-214AA mechanical compatibility with automated SMT assembly.

Technical Context

This discrete silicon rectifier uses a glass-passivated PN junction optimized for fast switching in high-frequency flyback and forward converters. Its 800 V peak reverse rating supports universal-input (85–265 V_AC) designs with margin against line transients.

The device operates across –55°C to +175°C junction temperature range and delivers stable performance under surge conditions up to 50 A (8.3 ms half-sine), enabling robust operation in unregulated or lightly loaded power stages.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast recovery rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R08	V_RRM = 800 V, t_rr = 75 ns, V_F = 1.15 V @ 2A - faster but higher cost	Better suited for >200 kHz resonant converters where ultra-low t_rr reduces EMI	Select STTH2R08 when t_rr < 100 ns is required; RS2K R5G preferred for cost-sensitive 65–130 kHz designs
ES2J	V_RRM = 600 V, t_rr = 35 ns, I_F = 2 A - lower voltage rating, faster recovery	Limited to 230 V_AC max input; insufficient margin for 265 V_AC + surge	ES2J is viable only in regions with regulated 230 V_AC mains; RS2K R5G ensures global universal-input compliance

Compared with STTH2R08 and ES2J, RS2K R5G offers optimal balance of 800 V robustness, 500 ns recovery, and SMB footprint cost efficiency for mainstream 65–130 kHz offline SMPS-without over-specifying speed or sacrificing surge margin.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for RS2K R5G?

The RS2K R5G has a V_RRM of 800 V, confirmed in the Absolute Maximum Ratings table of Taiwan Semiconductor's RS2A–RS2M datasheet (Version L2304). This rating applies across the full operating temperature range and supports universal-input AC/DC designs with adequate transient margin.

Does RS2K R5G have a specified reverse recovery time (t_rr)?

Yes, RS2K R5G has a maximum reverse recovery time of 500 ns under test conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, as documented in the Electrical Specifications section of the official datasheet. This value is specific to the RS2K variant and differs from other members of the RS2x family.

What package type does RS2K R5G use, and is it compatible with standard SMB footprints?

RS2K R5G uses the DO-214AA (SMB) package, with mechanical dimensions matching JEDEC DO-214AA Issue D. The suggested pad layout (4.60 × 2.60 mm) and terminal configuration are fully compatible with industry-standard SMB land patterns used for automated SMT assembly.

Is RS2K R5G RoHS compliant and halogen-free?

Yes, RS2K R5G is RoHS compliant and halogen-free, as explicitly stated in the Features section of the Taiwan Semiconductor RS2A–RS2M datasheet. These attributes meet IPC-1752A material declaration requirements and support compliance with EU Directive 2011/65/EU and IEC 61249-2-21.

What is the junction-to-ambient thermal resistance (R_θJA) for RS2K R5G?

The junction-to-ambient thermal resistance for RS2K R5G is 55 °C/W, measured under standard JEDEC test conditions on a 1-inch² copper pad. This value assumes no additional heatsinking and must be applied with appropriate derating for sustained 2 A operation in enclosed environments.
