Product details
Overview
RS1JH from Taiwan Semiconductor is a 1A, 600V fast recovery surface-mount rectifier diode in DO-214AC (SMA) package, featuring 250 ns reverse recovery time, 1.3 V max forward voltage at 1 A, and 5 µA max reverse leakage at 25°C - used in automotive DC-DC converters and snubber circuits.
For engineers reviewing the RS1JH datasheet, RS1JH pinout, RS1JH application, or RS1JH equivalent, this page delivers verified electrical specs, thermal resistance values (RθJA = 105°C/W), AEC-Q101 qualification status, and direct alternative part comparisons for high-reliability power conversion designs.
Technical Context
The RS1JH operates as a single-die, unidirectional fast recovery rectifier with glass-passivated junction for enhanced reliability under thermal cycling. Its 600 V repetitive peak reverse voltage (VRRM) and 30 A non-repetitive surge rating support transient-heavy automotive and industrial power rails.
Designed for automated SMT assembly, it meets J-STD-020 moisture sensitivity level 1 and JESD201 Class 2 whisker resistance. The cathode band polarity marking and matte tin-plated leads ensure consistent solderability per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input stages in 48 V automotive systems and industrial 380 V AC-derived supplies |
| IF | 1 A continuous - suitable for low-to-medium power DC-DC output rectification |
| trr | 250 ns - enables efficient operation up to ~200 kHz switching frequencies in flyback and forward converters |
| VF max | 1.3 V @ 1 A, 25°C - limits conduction loss to ≤1.3 W at full rated current |
| RθJA | 105 °C/W - requires minimal PCB copper area for thermal management in ambient ≤70°C environments |
| IR max | 5 µA @ 25°C - ensures low standby leakage in battery-backed or always-on subsystems |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | Same 1 A / 600 V rating; trr = 200 ns (slightly faster); RθJA = 90°C/W (better thermal dissipation) | Optimized for higher-frequency SMPS; slightly tighter VF distribution (1.15 V typ) | Preferred where board space permits larger SMC package and higher efficiency is critical |
| ON Semi MUR160 | Same DO-214AC package; trr = 500 ns (slower); VF max = 1.25 V (lower conduction loss) | Better suited for lower-switching-frequency (<100 kHz) applications with higher surge tolerance (IFSM = 50 A) | Select when cost sensitivity outweighs speed requirement and surge robustness is prioritized |
Compared with STTH1R06 and MUR160, the RS1JH offers balanced performance: AEC-Q101 qualification for automotive use, 250 ns recovery for mid-frequency converters, and DO-214AC compatibility with tight layout constraints - making it optimal for space-constrained, thermally moderate, and automotive-grade designs.

FAQ
What is the maximum junction temperature rating for RS1JH?
The RS1JH has a maximum junction temperature (TJ) of +175°C, enabling reliable operation in under-hood automotive environments and sealed industrial enclosures. This rating is validated per AEC-Q101 stress testing and allows full 1 A current capability up to 85°C ambient when mounted on a standard 1-inch² 2-oz copper pad. Derating begins above that ambient temperature per the forward current derating curve in the RS1JH datasheet.
Is RS1JH pin-compatible with other devices in the RS1xH series?
Yes, all RS1xH devices including RS1JH share identical DO-214AC (SMA) package dimensions, lead pitch, and cathode band polarity marking - enabling drop-in replacement across voltage grades (50 V to 1000 V). However, electrical parameters such as VRRM, trr, and IR differ per variant, so circuit validation is required when substituting RS1JH for RS1AH or RS1MH in existing designs.
Does RS1JH meet automotive qualification standards?
Yes, RS1JH is AEC-Q101 qualified, having passed stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (uHAST). This certification confirms suitability for automotive powertrain, chassis, and body electronics applications where reliability under thermal and mechanical stress is mandatory - a key differentiator versus non-qualified general-purpose rectifiers.
What is the reverse recovery time (trr) specification for RS1JH?
The RS1JH has a maximum reverse recovery time (trr) of 250 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the Electrical Specifications table of the official RS1JH datasheet (Version B2304, Page 2) and reflects its optimized fast-recovery design for switching frequencies up to 200 kHz in DC-DC converters and snubber networks.
Can RS1JH be used in lead-free reflow processes?
Yes, RS1JH is fully compatible with lead-free reflow soldering per JEDEC J-STD-020. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its DO-214AC package is rated for peak reflow temperatures up to 260°C. With moisture sensitivity level 1, RS1JH does not require dry-packaging or pre-baking before assembly - simplifying manufacturing logistics and reducing process risk.
