Product details
Overview
RS2MFSH from Taiwan Semiconductor is a 2 A, 1000 V fast recovery surface-mount rectifier in SOD-128 package, featuring 500 ns reverse recovery time, 1.06 V forward voltage at 2 A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in high-voltage DC/DC converters.
For engineers reviewing the RS2MFSH datasheet, RS2MFSH pinout, RS2MFSH application, or RS2MFSH equivalent, key selection criteria include peak reverse voltage rating (1000 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 RS2MFSH employs a glass-passivated silicon die in a single-die configuration, optimized for fast switching with low conduction loss. Its 1000 V VRRM and 500 ns trr enable use in high-frequency, high-voltage power conversion where rapid turn-off minimizes switching losses.
Thermal performance is defined by RθJL = 16 °C/W and RθJA = 73 °C/W on a 5 mm × 5 mm copper pad PCB, supporting continuous 2 A operation up to +125 °C ambient when properly heatsinked via lead termination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse blocking voltage without breakdown; enables use in 800 V DC bus systems with safety margin. |
| IF | 2 A - Continuous average forward current rating; supports sustained power delivery in compact SOD-128 footprint. |
| trr | 500 ns - Measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; ensures minimal switching loss in 100–500 kHz converters. |
| VF @ 2 A, 25°C | 1.06 V - Forward voltage drop determines conduction loss; yields ~2.12 W dissipation at full load. |
| RθJL | 16 °C/W - Junction-to-lead thermal resistance; allows direct thermal path to PCB copper, critical for high-power density layouts. |
| Junction Temp Range | –55 to +175 °C - Full operational range supports under-hood automotive environments and industrial power supplies. |
Pinout & Package
Package: SOD-128 - Low-profile, surface-mount plastic package with matte tin-plated leads (J-STD-002 compliant), cathode indicated by band, weight ≈ 0.027 g, UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06DJF | 600 V VRRM, 2 A, 50 ns trr, TO-277A package | Higher speed but lower voltage rating; unsuitable for >600 V systems | Select when ultra-fast recovery (<100 ns) is prioritized over 1000 V blocking capability. |
| ES2J-M3/84A | 600 V VRRM, 2 A, 35 ns trr, SMA package | Smaller footprint but lower thermal mass; limited to <1.5 A continuous in same layout | Choose for space-constrained consumer designs where 600 V rating suffices and layout area is critical. |
Compared with STTH2R06DJF and ES2J-M3/84A, the RS2MFSH uniquely delivers 1000 V blocking with AEC-Q101 qualification and SOD-128 thermal performance-making it the only option among the three for automotive 800 V systems requiring both high voltage and automotive reliability.

FAQ
What is the maximum junction temperature rating for RS2MFSH?
The RS2MFSH has a maximum junction temperature (TJ) of +175 °C and a minimum of –55 °C. This wide range supports operation in under-hood automotive environments and high-ambient industrial settings. The device maintains specified electrical parameters across this full range, and thermal design must ensure junction temperature remains below 175 °C under worst-case power dissipation and ambient conditions. RS2MFSH's RθJL = 16 °C/W enables effective heat transfer to PCB copper.
Is RS2MFSH suitable for automotive applications?
Yes, RS2MFSH is AEC-Q101 qualified and explicitly listed for automotive applications in its official documentation. It meets stringent requirements for temperature cycling, mechanical shock, and long-term reliability in engine control, ADAS, and electrified powertrain systems. The glass-passivated junction and J-STD-020 Level 1 moisture sensitivity further validate its suitability for automotive manufacturing processes and field deployment.
What is the reverse recovery time (trr) of RS2MFSH and how is it measured?
The RS2MFSH has a reverse recovery time (trr) of 500 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter reflects the time required for the diode to transition from forward conduction to reverse blocking state. The value is confirmed in the manufacturer's electrical specifications table and directly impacts switching loss in high-frequency converters-lower trr reduces energy dissipation during turn-off transitions in the RS2MFSH.
Does RS2MFSH have a halogen-free and RoHS-compliant construction?
Yes, RS2MFSH is both RoHS compliant and halogen-free, as explicitly stated in its features list. The molding compound, lead finish (matte tin), and internal materials meet EU RoHS Directive 2011/65/EU and IEC 61249-2-21 standards for halogen content. These compliance attributes are verified per manufacturer documentation and support environmentally regulated industrial and automotive end equipment.
What is the marking code printed on the RS2MFSH device body?
The RS2MFSH is marked with "RS2MFH" on its top surface, per the ordering information table in the datasheet. This marking code omits the final "S" to fit the SOD-128 package's limited real estate, while retaining unambiguous identification within the RS2xFSH family. The cathode is indicated by a visible band adjacent to the marking, ensuring correct orientation during automated placement and manual inspection of the RS2MFSH.
