Product details
Overview
RS2JFSH from Taiwan Semiconductor is a 2A, 600V fast recovery surface-mount rectifier in SOD-128 package, featuring 250 ns reverse recovery time, 1.01 V forward voltage at 2A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in DC/DC converters where low conduction loss and fast switching are critical.
For engineers reviewing the RS2JFSH datasheet, RS2JFSH pinout, RS2JFSH application, or RS2JFSH equivalent, key selection criteria include peak reverse voltage (600 V), thermal resistance (RθJL = 16 °C/W), junction temperature range (–55 to +175 °C), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
The RS2JFSH uses a glass-passivated silicon die optimized for fast recovery (trr = 250 ns max) and low forward voltage drop. Its single-die configuration and SOD-128 package support high-density automated PCB assembly while maintaining robust thermal performance (RθJL = 16 °C/W).
Designed for operation up to 175 °C junction temperature, it delivers stable reverse leakage (< 1 µA at 25 °C, < 40 µA at 125 °C) and low junction capacitance (11 pF at 1 MHz, 4 V), enabling efficient high-frequency rectification in automotive and industrial power supplies.
Key Specifications

| RθJL | 16 °C/W - Junction-to-lead thermal resistance; allows direct heat transfer to PCB copper, simplifying thermal management |
| IFSM | 50 A - Non-repetitive surge current (8.3 ms); withstands inrush and fault transients in automotive power rails |
| CJ | 11 pF - Junction capacitance at 1 MHz / 4 V; minimizes capacitive coupling noise in high-speed switching nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06S | Same 2 A / 600 V rating; trr = 150 ns (faster), but RθJA = 90 °C/W (higher than RS2JFSH's 73 °C/W) | Better for ultra-high-frequency designs (>500 kHz); less suitable for thermally constrained layouts without forced cooling | Prefer RS2JFSH when board-level thermal dissipation dominates over switching speed requirements |
| ES2J | Same SOD-128 package; trr = 35 ns (much faster), but VF = 1.7 V @ 2 A (higher conduction loss) | Optimized for minimal reverse recovery loss in resonant topologies; trades efficiency for speed | Choose RS2JFSH where forward loss and thermal management are prioritized over sub-100 ns recovery |
Compared with STTH2R06S and ES2J, RS2JFSH balances moderate trr (250 ns), low VF (1.01 V), and superior thermal resistance (RθJL = 16 °C/W), making it optimal for automotive and industrial DC/DC converters requiring reliability, efficiency, and ease of thermal integration.

FAQ
What is the maximum junction temperature rating for RS2JFSH?
The RS2JFSH has a maximum junction temperature (TJMAX) of +175 °C, verified per absolute maximum ratings in the official datasheet. This rating enables reliable operation in under-hood automotive environments and sealed industrial enclosures. The RS2JFSH maintains specified electrical performance-including reverse leakage and forward voltage-across its full –55 °C to +175 °C junction temperature range, supporting designs without active cooling.
Is RS2JFSH pin-compatible with other parts in the RS2xFSH series?
Yes, all RS2xFSH variants-including RS2DFSH, RS2GFSH, RS2JFSH, RS2KFSH, and RS2MFSH-share identical SOD-128 package dimensions, pinout (anode/cathode), and mounting footprint. The only differences are rated VRRM (200–1000 V) and associated parameters like trr and VF. Therefore, RS2JFSH can be substituted within the same family without PCB layout changes, provided voltage and recovery time requirements are met.
What does the "J" in RS2JFSH indicate?
The "J" in RS2JFSH denotes the 600 V repetitive peak reverse voltage (VRRM) rating, per Taiwan Semiconductor's standardized ordering code: D=200 V, G=400 V, J=600 V, K=800 V, M=1000 V. This letter is part of the device marking (RS2JFH) and directly correlates to the absolute maximum VRRM value confirmed in the datasheet's "Absolute Maximum Ratings" table.
Does RS2JFSH require special handling due to moisture sensitivity?
No, RS2JFSH is rated J-STD-020 Moisture Sensitivity Level 1, meaning it has unlimited floor life at standard room conditions (≤30 °C / 60% RH) and requires no baking prior to reflow soldering. This eliminates process steps and risk of popcorning, simplifying manufacturing for high-volume automotive and industrial SMT lines using the RS2JFSH.
How does RS2JFSH compare to standard PN-junction rectifiers in terms of recovery speed?
RS2JFSH is a fast recovery rectifier with trr = 250 ns (max), significantly faster than general-purpose rectifiers (e.g., 1N4007: trr > 2 µs). This reduced recovery time minimizes switching losses and EMI in high-frequency DC/DC converters. Unlike standard rectifiers, RS2JFSH achieves this via optimized carrier lifetime control and glass passivation-confirmed in its "Electrical Specifications" table and validated under AEC-Q101 stress testing.
