Product details
Overview
FR201G from Taiwan Semiconductor is a 2A, 50V fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 1.3V max forward voltage at 2A, 55A surge current capability, 150°C max junction temperature, and 150ns reverse recovery time - used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the FR201G datasheet, FR201G pinout, FR201G application, or FR201G equivalent, key selection criteria include repetitive peak reverse voltage (50V), thermal resistance (70°C/W), junction capacitance (10pF), AEC-Q101 qualification status, and DO-15 mechanical compatibility with standard through-hole PCB layouts.
Technical Context
The FR201G employs a glass-passivated silicon PN junction optimized for fast recovery (trr ≤ 150ns) and low conduction loss. Its single-die configuration supports unidirectional current flow with cathode-band polarity marking and pure tin-plated leads compliant with J-STD-002 solderability.
Designed for high-efficiency switching applications, it delivers 5µA max reverse leakage at 25°C and 100µA at 125°C, with junction-to-ambient thermal resistance of 70°C/W enabling stable operation up to 150°C junction temperature under defined derating conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | Same 2A/600V rating but higher VF (1.7V typ), longer trr (200ns), TO-220AC package | Requires heatsink mounting; unsuitable for space-constrained DO-15 footprints | Select when higher VRRM (600V) is needed and thermal budget allows TO-220 footprint |
| 1N4933 | Lower VRRM (200V), slower trr (500ns), same DO-15 package and 2A rating | Limited to low-voltage, low-frequency (<100kHz) rectification; not suitable for high-efficiency SMPS | Choose only for cost-sensitive, non-switching or low-frequency linear supply applications |
Compared with STTH2R06 and 1N4933, the FR201G uniquely balances 50V VRRM, 150ns trr, and DO-15 compatibility - making it optimal for compact, high-frequency, low-voltage DC-DC stages where thermal and layout constraints dominate.

FAQ
What is the maximum junction temperature rating for FR201G?
The FR201G has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version H2105. This rating enables reliable operation in enclosed industrial power supplies and automotive auxiliary modules where ambient temperatures reach 85°C, provided thermal design respects the 70°C/W junction-to-ambient resistance. Derating curves confirm usable current capacity down to zero amps at 150°C ambient.
Does FR201G meet automotive qualification standards?
The base FR201G is not AEC-Q101 qualified; however, the FR201GH variant - explicitly marked with "H" in the ordering code - is fully AEC-Q101 qualified and undergoes stress testing for temperature cycling, humidity, and mechanical shock. Engineers selecting FR201G for automotive use must specify FR201GH to ensure compliance; the "G" suffix alone indicates commercial-grade construction.
What is the reverse recovery time (trr) of FR201G and how is it measured?
The FR201G has a reverse recovery time (trr) of ≤150ns, measured under standardized conditions: IF = 0.5A, IR = 1.0A, Irr = 0.25A, per the test circuit diagram in Taiwan Semiconductor's FR201G–FR207G datasheet (Version H2105, Page 4). This value reflects the diode's speed in transitioning from forward conduction to reverse blocking - critical for minimizing switching losses in high-frequency power converters.
Is FR201G compatible with lead-free reflow soldering processes?
Yes, FR201G features pure tin-plated leads compliant with J-STD-002 for solderability, and its DO-204AC (DO-15) package is rated for lead-free reflow profiles up to 260°C peak temperature. The UL 94V-0 molding compound remains stable under standard IPC/JEDEC J-STD-020 moisture sensitivity level (MSL) 1 conditions, eliminating pre-bake requirements for typical SMT assembly lines.
How does FR201G differ from FR202G in terms of voltage rating and application scope?
The FR201G is rated for 50V repetitive peak reverse voltage (VRRM), while FR202G is rated for 100V - doubling the reverse blocking capability. Both share identical forward current (2A), surge rating (55A), and package (DO-15), but FR202G's higher VRRM makes it suitable for 48V input systems or higher-line-voltage rectification where FR201G would risk avalanche failure. Designers must verify VRRM margin against worst-case transient voltages in their specific topology.
