Product details
Overview
RS2GAHR3G from Taiwan Semiconductor is a 1.5A, 400V fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 50A peak surge current, 175°C max junction temperature, and 150ns reverse recovery time - used in DC-DC converters and snubber circuits.
For engineers reviewing the RS2GAHR3G datasheet, RS2GAHR3G pinout, RS2GAHR3G application, or RS2GAHR3G equivalent, key selection criteria include VRRM = 400V, IF = 1.5A, trr = 150ns, RθJA = 55°C/W, and DO-214AC mechanical compatibility with automated SMT placement.
Technical Context
This single-die fast recovery rectifier uses glass-passivated junction technology to achieve low leakage (≤5µA @ 25°C, ≤200µA @ 125°C) and stable switching performance across -55°C to +175°C operating range. Its 18°C/W junction-to-lead thermal resistance supports high-reliability power conversion under sustained load.
The device meets J-STD-020 moisture sensitivity level 1 and JESD201 Class 2 whisker resistance requirements. Matte tin-plated leads ensure solderability per J-STD-002, and UL 94V-0 molding compound provides flame-retardant encapsulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse voltage before breakdown; defines safe blocking capability in 400V-rated power rails |
| IF | 1.5 A - continuous forward current rating; determines steady-state conduction capacity in DC-DC output stages |
| trr | 150 ns - reverse recovery time at IF=0.5A/IR=1.0A; enables high-frequency switching (>100kHz) with low switching loss |
| IFSM | 50 A - non-repetitive surge current for 8.3ms half-sine; supports inrush and fault-current handling in SMPS inputs |
| TJ max | +175 °C - maximum junction temperature; allows operation in thermally constrained industrial environments without derating |
| RθJA | 55 °C/W - junction-to-ambient thermal resistance; informs heatsinking requirements on standard FR-4 PCB with minimal copper |
| VF | ≤1.3 V - forward voltage at IF=1.5A/25°C; sets conduction loss baseline (≈1.95W max dissipation) |
| CJ | 50 pF - junction capacitance at 1MHz/4V; impacts high-frequency noise coupling and EMI filter design |
Pinout & Package
DO-214AC (SMA) surface-mount package with molded plastic body (4.60 × 2.83 × 2.30 mm), cathode band marking, matte tin-plated leads, and UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of bridge or input rail; requires thermal relief pad for soldering reliability |
| Cathode | Forward current exit / reverse voltage blocking terminal | Marked by visible band; ties to output node or switching node; critical for polarity-sensitive snubber placement |
Key Features
| Feature | Design Value |
|---|---|

| J-STD-002 solderable leads | Ensures consistent wetting and joint integrity with lead-free SAC305 and SnPb pastes on production lines |
Applications
| DC-DC Converter Output Rectification | Snubber Network Diode |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 12–48V outputs at up to 1.5A. IC Role / Device Role / Timing Role: Unidirectional current conduction path during transformer demagnetization phase; blocks reverse voltage during primary switch ON-time. Use Value: 150ns trr minimizes reverse recovery charge (Qrr) and associated switching loss, improving efficiency by ~0.8% over 500ns alternatives at 250kHz. | Use Scenario: RC snubber across MOSFET drain-source or IGBT collector-emitter in motor drives and inverters. IC Role / Device Role / Timing Role: Fast clamping diode that conducts transient energy during voltage overshoot, then recovers before next switching edge. Use Value: Low CJ (50pF) and fast trr prevent snubber resonance distortion and reduce stress on switching devices during hard commutation. |
| Switching Mode Inverter Input Stage | LED Driver Bulk Rectification |
Use Scenario: Input AC-DC rectification feeding H-bridge inverter stages for HVAC compressors and UPS systems. IC Role / Device Role / Timing Role: High-voltage, high-surge-capable rectifier converting 230VAC-derived DC bus (≈325V peak) into stable bulk supply. Use Value: 400V VRRM provides 25% margin over 325V peak, while 50A IFSM withstands line transients and startup surges without failure. | Use Scenario: Off-line LED driver input stage converting 120/230VAC to DC for constant-current LED strings. IC Role / Device Role / Timing Role: Primary rectifier in bridge or single-phase configuration; handles continuous 1.5A output with low forward drop. Use Value: ≤1.3V VF limits conduction loss to <2W, reducing thermal load on compact enclosed drivers and extending electrolytic capacitor life. |
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 = 600V, trr = 75ns, IF = 1A, DO-214AC | Higher voltage rating but lower current; faster recovery enables >500kHz operation | Preferred where higher VRRM margin or ultra-fast switching is required, but derate current to 1A |
| ON Semi MUR160 | VRRM = 600V, trr = 50ns, IF = 1A, DO-41 axial | Superior speed and voltage, but axial package incompatible with SMT automation | Only suitable for through-hole prototyping or legacy designs; not drop-in for RS2GAHR3G |
Compared with STTH1L06S and MUR160, RS2GAHR3G offers optimal balance of 400V blocking, 1.5A current, and 150ns recovery in an SMT-optimized DO-214AC package - making it ideal for cost-sensitive, high-volume DC-DC and lighting applications requiring automated assembly.

FAQ
What is the maximum junction temperature rating for RS2GAHR3G?
The RS2GAHR3G has a maximum junction temperature (TJ) rating of +175°C. This allows reliable operation in high-ambient environments such as enclosed LED drivers or industrial motor control enclosures. The device maintains specified electrical parameters up to this limit, and its 18°C/W junction-to-lead thermal resistance supports effective heat transfer to the PCB when using recommended pad layouts. Always verify board-level thermal performance in final layout for RS2GAHR3G.
Does RS2GAHR3G meet RoHS and halogen-free requirements?
Yes, RS2GAHR3G complies with EU RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants, and lead content is below 1000 ppm. These specifications are verified in TSC's material declarations and supported by third-party test reports. RS2GAHR3G is suitable for environmentally regulated markets including Europe, Japan, and North America.
What is the reverse recovery time (trr) of RS2GAHR3G and how is it measured?
The RS2GAHR3G has a reverse recovery time (trr) of 150 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC test method. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss in high-frequency converters. The 150 ns trr is confirmed in the official TSC datasheet Version I2304 and applies specifically to RS2GAHR3G - not extrapolated from adjacent variants.
Is RS2GAHR3G compatible with lead-free reflow soldering processes?
Yes, RS2GAHR3G is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the device is rated for peak reflow temperatures up to 260°C (per J-STD-020 Level 1). No pre-bake is required due to its moisture sensitivity level 1 classification. RS2GAHR3G performs reliably in standard SAC305 profiles with 60–90 second exposure above 217°C.
How does RS2GAHR3G differ from RS2JAHR3G in terms of electrical performance?
RS2GAHR3G (400V VRRM) and RS2JAHR3G (600V VRRM) share identical package, current rating (1.5A), thermal specs, and construction, but differ in reverse voltage capability and reverse recovery time: RS2GAHR3G has trr = 150 ns, while RS2JAHR3G is rated at 250 ns. This trade-off reflects optimized carrier lifetime for higher voltage blocking. Select RS2GAHR3G where 400V margin suffices and faster switching is prioritized.
