Product details
Overview
RS2DFL from Taiwan Semiconductor is a 2 A, 200 V fast recovery surface-mount rectifier in SOD-123FL package, featuring 0.94 V forward voltage at 2 A/25°C, 150 ns reverse recovery time, and 81 °C/W junction-to-lead thermal resistance - deployed in DC-DC converters and switching-mode inverters.
For engineers reviewing the RS2DFL datasheet, RS2DFL pinout, RS2DFL application, or RS2DFL equivalent, key selection criteria include repetitive peak reverse voltage (200 V), surge current rating (40 A), low leakage (<5 µA @ 25°C), thermal performance on PCB, and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
The RS2DFL employs a single-die, glass-passivated PN junction optimized for fast recovery (trr ≤ 150 ns) and low conduction loss. Its SOD-123FL package enables automated placement and meets JESD201 Class 1 whisker resistance with matte tin-plated leads.
Thermal design is supported by verified RθJL = 81 °C/W and RθJA = 116 °C/W on a 5 mm × 5 mm Cu pad, while electrical stability is maintained across -55°C to +150°C junction temperature range and <150 µA IR at 125°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MURS220T3G | VRRM = 200 V, IF = 2 A, trr = 35 ns (faster), RθJA = 125 °C/W (higher) | Better high-frequency efficiency but higher thermal resistance limits power density | Preferred where switching frequency exceeds 1 MHz and board space allows larger thermal pads |
| Vishay ES2D-E3/57T | VRRM = 200 V, IF = 2 A, trr = 35 ns, VF = 0.95 V @ 2 A, same SOD-123FL package | Near-identical footprint and ratings; tighter VF tolerance but no J-STD-201 whisker data published | Suitable for drop-in replacement where whisker testing is not mandated by end-equipment standard |
Compared with MURS220T3G and ES2D-E3/57T, the RS2DFL offers superior thermal resistance (RθJL = 81 °C/W) and documented JESD201 Class 1 whisker resistance - making it preferred for thermally constrained industrial modules requiring long-term reliability validation.

FAQ
What is the maximum junction temperature rating for RS2DFL?
The RS2DFL has a maximum junction temperature (TJMAX) of +150°C, validated across its full operating range from -55°C to +150°C. This rating enables reliable use in enclosed industrial power supplies and automotive under-hood auxiliary systems where ambient temperatures exceed 85°C. The RS2DFL maintains specified electrical parameters up to this limit when mounted on a 5 mm × 5 mm copper pad per JEDEC standards.
Does RS2DFL support automated pick-and-place assembly?
Yes, the RS2DFL is explicitly designed for automated placement, as confirmed by its SOD-123FL package, matte tin-plated leads compliant with J-STD-002, and moisture sensitivity level 1 per J-STD-020 - eliminating pre-bake requirements. The RS2DFL's standardized tape-and-reel packaging (10,000 units per reel) further ensures seamless integration into high-volume SMT lines.
What is the reverse recovery time (trr) of RS2DFL and how is it measured?
The RS2DFL 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. This value is specified in the official Taiwan Semiconductor datasheet Version B2103 and reflects performance at 25°C ambient. The RS2DFL's trr remains stable across temperature, supporting consistent switching behavior in high-frequency SMPS designs.
Is RS2DFL RoHS and halogen-free compliant?
Yes, the RS2DFL is fully RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the official Taiwan Semiconductor documentation. This compliance is verified through material declarations and third-party testing, ensuring the RS2DFL meets environmental requirements for CE-marked industrial equipment and export-controlled products.
What is the marking code printed on the RS2DFL device body?
The RS2DFL is marked with "R2DF" on its surface, as specified in the Absolute Maximum Ratings table of the Taiwan Semiconductor datasheet. This 4-character code distinguishes it within the RS2xFL family and aligns with the "x = D" designation for the 200 V variant. The RS2DFL marking also includes date and factory codes per standard SOD-123FL labeling practice.
