Product details
Overview
RS2MA R3G from Taiwan Semiconductor is a 1.5A, 1000V 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 200 µA max reverse leakage at 125°C - used in high-voltage DC-DC converters and snubber circuits.
For engineers reviewing the RS2MA R3G datasheet, RS2MA R3G pinout, RS2MA R3G application, or RS2MA R3G equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (RθJL = 18°C/W), junction temperature range (–55°C to +175°C), and JEDEC-compliant DO-214AC mechanical outline.
Technical Context
This single-die fast recovery rectifier uses glass-passivated junction technology to achieve stable switching performance under repetitive surge conditions (IFSM = 50 A, 8.3 ms half-sine). Its 1000 V VRRM and 500 ns trr support high-frequency operation in flyback and forward converter topologies.
Thermal design is enabled by low junction-to-lead resistance (18°C/W) and UL 94V-0 molding compound. Polarity is marked by cathode band; matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 2 whisker requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports primary-side rectification in offline SMPS with ≥600 V DC bus |
| IF | 1.5 A continuous - suitable for medium-power output stages up to ~30 W |
| trr | 500 ns - enables operation up to ~200 kHz with reduced switching loss vs. standard rectifiers |
| VF max | 1.3 V @ 1.5 A - limits conduction loss to ≤1.95 W at full load |
| RθJL | 18 °C/W - allows direct PCB copper pour heat sinking without external heatsink |
| TJ max | +175 °C - enables reliable operation in sealed industrial enclosures with ambient up to +105 °C |
| IFSM | 50 A - withstands inrush and transient surges in AC-input front-end designs |

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 | VRRM = 600 V, trr = 35 ns, IF = 1 A | Limited to ≤600 V systems; lower current rating requires parallel use for 1.5 A loads | Select when ultra-fast recovery (<50 ns) is prioritized over voltage rating and current capacity |
| ON Semi MUR160 | VRRM = 600 V, trr = 75 ns, IF = 1 A, DO-41 | Through-hole only; insufficient VRRM for 1000 V designs; not surface-mount compatible | Choose only for legacy through-hole designs where 600 V rating is sufficient and rework is acceptable |
Compared with STTH1L06S and MUR160, RS2MA R3G uniquely delivers 1000 V blocking capability in SMA package with 1.5 A rating and 500 ns recovery - enabling single-device solutions in high-voltage industrial and lighting power supplies where alternatives require derating or redesign.

FAQ
What is the maximum junction temperature rating for RS2MA R3G?
The RS2MA R3G has a maximum junction temperature (TJ) of +175°C and a minimum of –55°C. This wide operating range allows RS2MA R3G to function reliably in sealed industrial enclosures or high-ambient environments such as LED streetlight drivers, where board temperatures may exceed 100°C. Derating curves in the datasheet define safe current limits above 25°C ambient.
Does RS2MA R3G have RoHS and halogen-free compliance?
Yes, RS2MA R3G is RoHS compliant and halogen-free per Taiwan Semiconductor's specification I2304. The molding compound contains no brominated flame retardants, and lead content is below 1000 ppm. This compliance supports export to EU, China, and South Korea markets and aligns with IPC-1752 material declaration requirements for electronics manufacturing.
What is the reverse recovery time (trr) of RS2MA R3G and how is it measured?
The RS2MA R3G has a reverse recovery time (trr) of 500 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the datasheet test circuit (Fig.6). This value reflects total recovery duration including storage and transition times, and is validated at TJ = 25°C. It directly impacts switching loss in high-frequency converters using RS2MA R3G.
Is RS2MA R3G pin-compatible with other devices in the RS2xx family?
Yes, all RS2xx devices-including RS2MA R3G-share identical DO-214AC (SMA) package dimensions, lead pitch, and cathode band polarity marking. This allows drop-in replacement across voltage grades (50 V to 1000 V) without PCB layout changes, provided thermal and electrical margins are verified for the specific application.
What is the thermal resistance from junction to lead (RθJL) for RS2MA R3G?
The junction-to-lead thermal resistance (RθJL) of RS2MA R3G is 18°C/W, measured per standard JEDEC test methods. This low value enables efficient heat transfer from the die to the PCB copper via the leads, supporting thermal management without additional heatsinking in most 1.5 A applications - a key advantage over higher-RθJL alternatives like DO-41 rectifiers.
