Product details
Overview
RS1JFSH from Taiwan Semiconductor is a 1A, 600V fast recovery surface-mount rectifier in SOD-128 package, featuring 250 ns reverse recovery time, 1.01 V forward voltage at 1.0A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in DC/DC converters and power supplies where low conduction loss and thermal robustness are required.
For engineers reviewing the RS1JFSH datasheet, RS1JFSH pinout, RS1JFSH application, or RS1JFSH equivalent, key selection criteria include its 600V VRRM, 30A IFSM, -55°C to +175°C operating junction temperature range, and SOD-128 mechanical compatibility with high-density PCB layouts.
Technical Context
The RS1JFSH employs a glass-passivated silicon junction optimized for fast switching in medium-voltage power conversion circuits. Its 250 ns trr and 7 pF junction capacitance support efficient operation in 100–500 kHz DC/DC topologies while minimizing switching losses and EMI generation.
Thermally, it delivers RθJL = 29°C/W and RθJA = 84°C/W on a 5 mm × 5 mm Cu pad, enabling sustained 1A continuous conduction without forced cooling in automotive under-hood environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06S | Same 1A/600V rating; trr = 150 ns (faster), VF = 1.15 V (higher), SOD-128 compatible but not identical footprint | Better suited for higher-frequency (>500 kHz) SMPS where speed outweighs conduction loss | Select STTH1R06S only if layout allows minor pad adjustment and system prioritizes switching speed over thermal rise |
| ES1J | Same 1A/600V; trr = 35 ns (much faster), VF = 1.7 V (significantly higher), DO-214AC package (larger, different mounting) | Preferred in ultra-fast snubbers or PFC boost diodes where minimal reverse recovery charge is critical | ES1J requires PCB redesign due to DO-214AC size and thermal pad differences; not drop-in for SOD-128 footprints |
Compared with STTH1R06S and ES1J, the RS1JFSH balances moderate speed (250 ns), low forward loss (1.01 V), and automotive-qualified SOD-128 packaging-making it optimal for cost-sensitive, thermally constrained 100–400 kHz automotive power stages where layout reuse and long-term reliability are primary concerns.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the RS1JFSH?
The RS1JFSH has a VRRM of 600 V, verified per Taiwan Semiconductor's B2304 datasheet. This rating defines the highest reverse voltage the device can block repeatedly without breakdown and is critical for selecting appropriate input voltage margins in buck, flyback, and snubber applications. The RS1JFSH is part of a family spanning 200 V to 1000 V, with RS1JFSH specifically designated for 600 V systems.
Is the RS1JFSH qualified for automotive applications?
Yes, the RS1JFSH is AEC-Q101 qualified, as explicitly stated in the official Taiwan Semiconductor datasheet. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life-ensuring suitability for under-hood and cabin electronics. The RS1JFSH's -55°C to +175°C operating range and JESD201 Class 2 whisker resistance further support its use in automotive power systems.
What is the reverse recovery time (trr) of the RS1JFSH and how is it measured?
The RS1JFSH has a reverse recovery time (trr) of 250 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the B2304 datasheet. This value reflects the time required for minority carriers to clear after forward conduction ceases, directly impacting switching loss and EMI in high-frequency converters. It is distinct from the RS1KFSH (500 ns) and RS1GFSH (150 ns) variants in the same family.
What package type does the RS1JFSH use and what are its key mechanical features?
The RS1JFSH uses the SOD-128 surface-mount package, defined by JEDEC DO-221AD. Key features include a low profile (0.90–1.10 mm height), matte tin-plated leads compliant with J-STD-002, moisture sensitivity level 1 (J-STD-020), and a cathode band for polarity identification. Its 5 mm × 5 mm copper pad thermal test board reference confirms RθJA = 84°C/W for layout thermal design.
Does the RS1JFSH have halogen-free and RoHS-compliant construction?
Yes, the RS1JFSH is both halogen-free and RoHS compliant, as confirmed in the "Features" section of the Taiwan Semiconductor datasheet. These attributes meet global environmental regulations and automotive OEM material declarations, supporting sustainable manufacturing and end-of-life processing. The molding compound also meets UL 94V-0 flammability standards, adding safety certification for enclosed power modules.
