Product details
Overview
RS3GH from Taiwan Semiconductor is a 3A, 400V fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 150 ns reverse recovery time, 100 A peak surge current, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary AC/DC or DC/DC conversion diode in high-efficiency power supplies.
For engineers reviewing the RS3GH datasheet, RS3GH pinout, RS3GH application, or RS3GH equivalent, key selection criteria include repetitive peak reverse voltage (400 V), forward voltage at 3 A (≤1.3 V), junction temperature range (–55°C to +175°C), thermal resistance (RθJL = 15 °C/W), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
The RS3GH employs a glass-passivated silicon junction optimized for fast switching and high surge tolerance. Its single-die configuration and DO-214AB (SMC) package support automated placement and reflow soldering per J-STD-002.
Designed for operation up to 175°C junction temperature, it delivers stable performance under transient overloads (100 A, 8.3 ms half-sine) and maintains low leakage (≤10 µA at 25°C, ≤250 µA at 125°C) across its rated 400 V reverse voltage.

| IF | 3 A - Continuous average forward current at TL = 75°C; determines steady-state power handling capability |
| IFSM | 100 A - Peak non-repetitive surge current (8.3 ms); supports inrush and fault-current resilience |
| trr | 150 ns - Reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables high-frequency switching efficiency |
| RθJL | 15 °C/W - Junction-to-lead thermal resistance; enables direct heatsinking via PCB copper pour or metal-core board |
| TJ max | +175 °C - Maximum junction temperature; allows operation in under-hood automotive environments |

Applications
| Automotive Lighting | DC/DC Converter Output Rectification |
|---|---|
Use Scenario: LED headlamp and daytime running light (DRL) power modules requiring compact, thermally robust rectification. IC Role / Device Role / Timing Role: Primary freewheeling and output rectifier in buck-derived constant-current drivers. Use Value: 175°C junction rating and AEC-Q101 qualification ensure uninterrupted operation under hood temperatures exceeding 125°C ambient. | Use Scenario: Secondary-side rectification in isolated 12 V–5 V/3.3 V flyback or forward converters for infotainment and ADAS ECUs. IC Role / Device Role / Timing Role: High-efficiency unidirectional current path with minimal conduction loss and fast turn-off. Use Value: 150 ns trr reduces reverse recovery charge (Qrr) and associated switching losses, improving converter efficiency by ~1.2% at 250 kHz. |
| Snubber Network Diode | Industrial Power Supply Input Stage |
Use Scenario: Clamp diode in RCD snubber circuits across MOSFETs or IGBTs in motor drives and inverters. IC Role / Device Role / Timing Role: Fast, low-leakage path for transient energy dissipation during switching transitions. Use Value: Low IR (≤10 µA @ 25°C) prevents snubber capacitor discharge drift; 100 A IFSM withstands repeated clamping events. | Use Scenario: Input rectification in industrial AC/DC front-ends where space-constrained SMC footprint replaces larger DO-201AD packages. IC Role / Device Role / Timing Role: General-purpose bridge or discrete rectifier in universal-input (85–265 VAC) SMPS designs. Use Value: DO-214AB (SMC) package offers 30% smaller PCB area than DO-201AD while maintaining identical thermal derating curves. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EYH04-M3/45 | Same 400 V VRRM, 3 A IF, but trr = 200 ns; RθJA = 55 °C/W vs. RS3GH's 50 °C/W | Slightly slower recovery increases switching loss in >300 kHz designs; higher thermal resistance limits power density | Prefer RS3GH where layout space or thermal margin is constrained |
| ON Semiconductor MUR340G | Identical VRRM, IF, trr (150 ns), but not AEC-Q101 qualified; RθJL = 18 °C/W | Not validated for automotive use; less suitable for under-hood or safety-critical lighting systems | Select RS3GH for automotive programs requiring AEC-Q101 documentation and traceable qualification data |
Compared with VS-3EYH04-M3/45 and MUR340G, the RS3GH provides superior thermal performance (RθJL = 15 °C/W), automotive qualification, and tighter reverse recovery consistency-making it optimal for space- and reliability-constrained 12 V–48 V automotive power stages.

FAQ
What is the maximum junction temperature rating for RS3GH?
The RS3GH has a maximum junction temperature (TJ) rating of +175°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version B2304. This allows sustained operation in under-hood automotive environments and high-ambient industrial power supplies. The RS3GH maintains specified electrical parameters up to this limit when thermal design adheres to RθJL = 15 °C/W and proper PCB copper area is provided.
Is RS3GH AEC-Q101 qualified and what does that cover?
Yes, RS3GH is explicitly AEC-Q101 qualified per the manufacturer's documentation. This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling, unbiased highly accelerated stress test (uHAST), and electrostatic discharge (HBM). The RS3GH's AEC-Q101 status confirms suitability for automotive electronic systems such as lighting, body control, and infotainment power rails.
What is the reverse recovery time (trr) of RS3GH and how is it measured?
The RS3GH 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, as specified in the Electrical Specifications table of the RS3AH–RS3MH datasheet. This value is confirmed across production lots and applies directly to the RS3GH variant; it enables efficient operation in switching power supplies operating up to 500 kHz.
Does RS3GH have a halogen-free and RoHS-compliant construction?
Yes, RS3GH is both halogen-free and RoHS compliant, as stated in the FEATURES section of the official Taiwan Semiconductor datasheet. The molding compound contains no brominated or chlorinated flame retardants, and lead content is below 1000 ppm. These attributes meet EU Directive 2011/65/EU and IPC-1752A reporting requirements for environmentally regulated electronics manufacturing.
What package type and marking code does RS3GH use?
RS3GH uses the DO-214AB (SMC) surface-mount package with standardized mechanical dimensions per JEDEC DO-214AB Issue D. Its marking code is "RS3G", laser-etched on the cathode-banded surface. The device features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance, ensuring reliable reflow assembly.
