Product details
Overview
RS2M R5G from Taiwan Semiconductor is a 2 A, 1000 V fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 500 ns reverse recovery time, 1.3 V max forward voltage at 2 A, and 5 µA max reverse leakage at 25°C. It serves as a primary-side output rectifier in high-efficiency AC/DC adapters and offline SMPS.
For engineers reviewing the RS2M R5G datasheet, RS2M R5G pinout, RS2M R5G application, or RS2M R5G equivalent, key selection criteria include peak repetitive reverse voltage (1000 V), surge current capability (50 A), thermal resistance (RθJA = 55 °C/W), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
This discrete diode operates as a unidirectional, single-die fast recovery rectifier with glass-passivated junction for enhanced reliability under repetitive surge stress. Its 500 ns trr enables operation in 100–500 kHz switching topologies while maintaining low conduction loss.
The device uses matte tin-plated leads compliant with J-STD-002 solderability and meets JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band on the DO-214AA molded body, and it carries RoHS-compliant, halogen-free construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports full-bridge rectification in universal-input 85–265 VAC SMPS without derating |
| IF | 2 A continuous - delivers stable DC output up to 24 W at 12 V with minimal thermal rise |
| IFSM | 50 A (8.3 ms half-sine) - withstands inrush surges during cold-start of power supplies |
| trr | 500 ns - reduces switching losses and EMI in high-frequency flyback and LLC converters |
| VF | ≤1.3 V @ 2 A, 25°C - limits conduction loss to ≤2.6 W at rated current |
| RθJA | 55 °C/W - requires ≤11 cm² copper pour for safe operation at full load in ambient ≤50°C |
| Junction Temp | −55 to +175°C - enables deployment in industrial enclosures without active cooling |
Pinout & Package
DO-214AA (SMB) surface-mount package with axial lead configuration: anode and cathode terminals formed by two coplanar metallized leads extending from opposite ends of the molded plastic body. Cathode identified by a distinct band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction path | Connected to AC input or transformer secondary; must handle full surge current and reverse blocking stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | Same 2 A / 600 V rating; 150 ns trr, higher VF (1.7 V typ) | Better suited for <600 V designs requiring ultra-fast recovery; lower voltage margin than RS2M R5G | Select when optimizing for speed over voltage headroom in sub-600 V systems |
| ON Semi MUR260 | 2 A / 600 V; 50 ns trr, VF = 1.75 V max; TO-220AC package | Requires through-hole mounting and heatsinking; unsuitable for space-constrained SMB layouts | Choose only if board layout allows TO-220 footprint and thermal management supports higher VF |
Compared with STTH2R06 and MUR260, RS2M R5G offers superior voltage margin (1000 V vs. 600 V) and SMB compatibility, making it optimal for universal-input offline SMPS where surge immunity and SMT scalability are critical.
