Product details
Overview
RS2GH from Taiwan Semiconductor is a 2 A, 400 V fast recovery surface-mount rectifier diode in DO-214AA (SMB) package, featuring 150 ns reverse recovery time, 1.3 V max forward voltage at 2 A, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in DC-DC converters and car lighting systems.
For engineers reviewing the RS2GH datasheet, RS2GH pinout, RS2GH application, or RS2GH equivalent, key selection criteria include its 400 V repetitive peak reverse voltage, 50 A surge rating, 175 °C maximum junction temperature, and moisture sensitivity level 1 compliance - all critical for high-reliability automotive and industrial power designs.
Technical Context
The RS2GH operates as a single-die, unidirectional fast recovery rectifier with glass-passivated junction and matte tin-plated leads. Its 150 ns trr and low 1.3 V VF enable efficient switching in mid-frequency (<100 kHz) power conversion stages where conduction and recovery losses must be balanced.
Thermally, it delivers RθJA = 55 °C/W and RθJL = 18 °C/W, supporting continuous 2 A operation up to 125 °C ambient when mounted on minimum recommended PCB copper area. The DO-214AA (SMB) package ensures compatibility with automated SMT placement and J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - blocks up to 400 V repetitive reverse voltage, suitable for 24–48 V system-derived bus rails with safety margin |
| IF | 2 A continuous - supports steady-state output rectification in compact DC-DC modules up to ~40 W |
| trr | 150 ns - enables efficient operation in flyback and forward converters switching up to ~100 kHz |
| VF | ≤1.3 V @ 2 A, 25°C - limits conduction loss to ≤2.6 W per device at full load |
| IFSM | 50 A @ 8.3 ms - withstands inrush and fault currents in automotive load-dump scenarios |
| TJ(max) | 175 °C - allows operation in under-hood environments with derating per Fig.1 curve |
| CJ | 50 pF @ 4 V - minimizes capacitive coupling noise in high dv/dt snubber applications |
Pinout & Package
DO-214AA (SMB) surface-mount package with cathode-indicated band; 2-terminal configuration (anode and cathode), no internal connections beyond the die. Leads are matte tin-plated, compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential node (e.g., switch node in flyback, ground return in freewheeling) |
| Cathode | Current exit point during forward conduction; marked by band | Connected to higher-potential node (e.g., output rail, VCC, or snubber capacitor positive) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, TC, and HAST - enables use without additional qualification effort |
| Glass passivated junction | Provides stable leakage performance and long-term reliability under humidity and thermal cycling |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to reflow; supports standard SMT assembly without dry-pack handling |
| UL 94V-0 molding compound | Ensures flame retardancy in enclosed automotive and industrial enclosures meeting safety standards |
| RoHS and halogen-free | Complies with EU RoHS Directive 2011/65/EU and JEDEC JS709C - supports green manufacturing and end-of-life recycling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R04 | Same 2 A / 400 V rating; trr = 35 ns (faster), VF = 1.35 V (slightly higher), DO-214AA package | Better suited for >200 kHz switching; higher cost and tighter layout tolerance due to faster switching noise | Select STTH2R04 only if trr < 50 ns is required and EMI filtering is available |
| ON Semi MUR240 | 2 A / 400 V; trr = 50 ns, VF = 1.25 V, same DO-214AA package and AEC-Q101 qualified | Lower VF improves conduction efficiency; faster trr demands careful PCB layout to avoid ringing | Prefer MUR240 where thermal budget is tight and layout controls dv/dt transients |
Compared with STTH2R04 and MUR240, the RS2GH offers balanced trr/VF trade-off and broader thermal margin (175 °C TJ), making it optimal for cost-sensitive automotive and industrial applications where moderate switching frequency and robustness outweigh ultra-fast recovery needs.

FAQ
What is the maximum junction temperature rating for RS2GH?
The RS2GH has a maximum junction temperature (TJ(max)) of +175 °C, verified per AEC-Q101 stress testing. This allows operation in under-hood automotive environments and high-ambient industrial settings when properly heatsinked or mounted on adequate PCB copper. Derating curves in the RS2AH–RS2MH datasheet (Fig.1) define safe current limits versus ambient temperature for RS2GH.
Is RS2GH pin-compatible with other devices in the RS2xH series?
Yes, all RS2xH devices-including RS2AH, RS2BH, RS2DH, RS2GH, RS2JH, RS2KH, and RS2MH-share identical DO-214AA (SMB) package dimensions, pinout, and thermal characteristics. Only the VRRM rating differs (50 V to 1000 V), so RS2GH can be substituted within the same footprint when 400 V blocking capability is required.
Does RS2GH meet automotive qualification standards?
Yes, RS2GH is AEC-Q101 qualified, meaning it has passed accelerated stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (uHAST). This certification confirms suitability for automotive power electronics such as body control modules, lighting drivers, and DC-DC converters.
What is the reverse recovery time (trr) specification for RS2GH?
The RS2GH has a maximum reverse recovery time (trr) of 150 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the RS2AH–RS2MH datasheet (Page 2, Electrical Specifications table). This value is confirmed for the RS2GH variant and distinguishes it from slower variants like RS2JH (250 ns) and RS2KH (500 ns).
What packaging and moisture sensitivity level does RS2GH have?
RS2GH is supplied in DO-214AA (SMB) package, tape-and-reel format (3,000 units per reel), and carries moisture sensitivity level (MSL) 1 per J-STD-020. This means RS2GH may be stored indefinitely at ≤30 °C/60% RH and requires no baking before standard lead-free reflow soldering - simplifying SMT line integration.
