Product details
Overview
RS2GAH from Taiwan Semiconductor is a 1.5A, 400V fast recovery surface-mount rectifier diode in DO-214AC (SMA) package, featuring 150 ns reverse recovery time, 1.3 V max forward voltage at 1.5 A, and 5 µA max reverse leakage at 25°C. It serves as primary output rectifier in automotive DC-DC converters and snubber circuits.
For engineers reviewing the RS2GAH datasheet, RS2GAH pinout, RS2GAH application, or RS2GAH equivalent, key selection criteria include repetitive peak reverse voltage (400 V), thermal resistance (18 °C/W junction-to-lead), AEC-Q101 qualification, moisture sensitivity level 1 compliance, and DO-214AC mechanical compatibility with automated placement.
Technical Context
The RS2GAH employs a glass-passivated single-die silicon junction optimized for fast switching in high-frequency power conversion. Its 150 ns trr and low 50 pF junction capacitance support efficient operation in 100–500 kHz DC-DC topologies while maintaining low conduction loss via 1.3 V VF max at rated current.
AEC-Q101 qualification confirms suitability for automotive under-hood environments, with guaranteed operation from –55°C to +175°C junction temperature and robustness against soldering thermal stress per J-STD-002 and whisker testing per JESD201 Class 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or forward converter secondary-side rectification |
| IF | 1.5 A - Continuous average forward current; determines thermal sizing of PCB copper and heatsinking in steady-state operation |
| trr | 150 ns - Reverse recovery time; directly impacts switching losses and EMI in high-frequency SMPS 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 | Same DO-214AC package; 600 V VRRM, 1.7 V VF max, 100 ns trr | Higher voltage rating suits 48 V systems; faster trr reduces EMI but increases cost | Select when >400 V blocking margin required and 100 ns trr improves system-level noise performance |
| ON Semiconductor MUR160 | DO-41 through-hole; 600 V VRRM, 1.0 V VF typ, 75 ns trr | Not surface-mount; incompatible with automated SMT assembly; requires manual or wave-solder process | Choose only for legacy through-hole designs where rework to SMT is not feasible |
Compared with STTH1L06S and MUR160, the RS2GAH offers optimal balance of 400 V rating, 150 ns trr, and AEC-Q101 qualification in a production-ready SMT package-making it preferred for new automotive and industrial SMT power designs where cost, reliability, and manufacturability are jointly prioritized.

FAQ
What is the maximum junction temperature rating for RS2GAH?
The RS2GAH has a maximum junction temperature (TJ) rating of +175°C, verified per absolute maximum ratings table in the official datasheet. This allows continuous operation in high-ambient environments such as engine compartments or enclosed industrial enclosures. Derating curves confirm usable current capacity down to –55°C, supporting wide automotive thermal cycling requirements. The RS2GAH maintains parameter stability across this full range when operated within specified voltage and current limits.
Is RS2GAH compatible with lead-free reflow soldering processes?
Yes, RS2GAH is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the DO-214AC package is rated for peak reflow temperatures up to 260°C per JEDEC J-STD-020. Moisture sensitivity level 1 eliminates pre-bake requirements, enabling direct placement into standard Pb-free reflow profiles without popcorn risk or delamination concerns. The RS2GAH has been validated in production automotive SMT lines using IPC-A-610 Class 3 processes.
Does RS2GAH have AEC-Q101 qualification documentation available?
Yes, RS2GAH carries full AEC-Q101 qualification per version B2304 of the official datasheet. Test reports cover stress tests including temperature cycling, high-temperature operating life, unbiased high-humidity storage, and mechanical shock-all performed to AEC-Q101-001 Rev D standards. Certification applies specifically to the RS2GAH variant and is documented in TSC's automotive qualification summary report, accessible upon request for qualified OEM design-in engagements involving RS2GAH.
What is the reverse recovery time (trr) specification for RS2GAH and how is it measured?
The RS2GAH has a maximum 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 the official datasheet. This value reflects the time required for minority carriers to clear after forward conduction ceases, directly impacting switching loss and EMI. The RS2GAH's 150 ns trr is confirmed across production lots using standardized double-pulse test circuits per JEDEC JESD24-11, ensuring consistency for high-frequency power design validation.
Can RS2GAH be used as a direct replacement for RS2DAH in an existing design?
No, RS2GAH is not a direct replacement for RS2DAH due to differing voltage ratings: RS2DAH is rated for 200 V VRRM, while RS2GAH is rated for 400 V VRRM. Although both share identical package, pinout, and thermal characteristics, substituting RS2GAH in a 200 V design introduces unnecessary overdesign and potential cost penalty without functional benefit. The RS2GAH should only replace RS2DAH if the circuit requires higher reverse voltage margin or operates near RS2DAH's derated limit. Always verify layout, thermal, and surge margins before interchange.
