Product details
Overview
FR303G R0G from Taiwan Semiconductor is a 3A, 200V fast recovery rectifier diode in DO-201AD package, featuring 150ns reverse recovery time, 1.3V max forward voltage at 3A, and 125A surge capability - used in DC-DC converters and switching inverters for high-efficiency power conversion.
For engineers reviewing the FR303G R0G datasheet, FR303G R0G pinout, FR303G R0G application, or FR303G R0G equivalent, key selection criteria include VRRM=200V, trr=150ns, VF≤1.3V at 3A, TJ max=150°C, and DO-201AD mechanical compatibility with automated through-hole or surface-mount reflow assembly.
Technical Context
This single-die fast recovery rectifier operates with low conduction loss and controlled reverse recovery behavior, enabling efficient high-frequency switching in SMPS topologies. Its 150ns trr and 30pF junction capacitance support stable operation up to several hundred kHz without excessive switching noise or ringing.
The device sustains repetitive 200V reverse voltage (VRRM), handles 125A non-repetitive surge current (IFSM), and maintains reliable performance across –55°C to +150°C junction temperature range - validated per JESD201 Class 2 whisker testing and RoHS/halogen-free compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse blocking voltage; defines safe operating ceiling in bridge or freewheeling configurations |
| IF | 3 A - continuous average forward current; sets thermal design baseline for heatsinking and PCB copper area |
| trr | 150 ns - measured at IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables clean turn-off in 100–300 kHz switchers |
| VF | ≤1.3 V at IF = 3A, TJ = 25°C - directly determines conduction loss (Pcond ≈ 3.9W) and thermal rise |
| RθJA | 35 °C/W - junction-to-ambient thermal resistance; used to calculate ΔTJ under real-world board layout conditions |
| IR | ≤5 µA at VR = 200V, TJ = 25°C - leakage level critical for standby power budgeting in energy-efficient designs |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking; leads are pure tin plated, solderable per J-STD-002, UL 94V-0 molded compound, 1.20g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node or ground return) in freewheeling or output rectification |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to higher-potential rail (e.g., output bus or transformer secondary) - blocks reverse current above 200V |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery time | 150 ns - reduces switching losses and EMI in high-frequency DC-DC stages |
| Low forward voltage | ≤1.3 V @ 3A - minimizes I²R conduction loss and improves system efficiency >90% at mid-load |
| High surge rating | 125 A IFSM (8.3 ms half-sine) - withstands inrush and fault transients without failure |
| Ambient-rated thermal performance | RθJA = 35 °C/W - supports operation up to 75°C ambient without forced cooling in open-frame supplies |
Applications
| DC-DC Converter Output Rectification | Switching Inverter Freewheeling Diode |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 12–48V/3A outputs. IC Role / Device Role / Timing Role: Power rectifier converting high-frequency AC from transformer secondary into regulated DC output. Use Value: 150ns trr prevents reverse recovery overlap with MOSFET switching edges, reducing shoot-through risk and improving efficiency by ~1.2% vs. standard rectifiers. | Use Scenario: Freewheeling path for inductive loads (e.g., motor windings or relay coils) in H-bridge inverters. IC Role / Device Role / Timing Role: Clamp diode providing low-impedance return path during MOSFET off-time to suppress inductive kick. Use Value: 125A IFSM safely absorbs 5× rated load surges; 200V VRRM covers 120VAC-derived bus voltages with margin. |
| AC-DC Adapter Input Bridge Leg | Industrial PLC Power Supply Input Stage |
Use Scenario: One leg of full-wave bridge rectifier in universal-input (90–264VAC) 36W adapters. IC Role / Device Role / Timing Role: High-current, fast-recovery diode handling 50/60Hz line frequency with minimal conduction loss. Use Value: 3A IF rating supports 1.5× peak line current; 1.3V VF ensures <0.5W dissipation per diode at full load. | Use Scenario: Input rectification in DIN-rail mounted 24V/5A industrial power supplies with wide ambient range. IC Role / Device Role / Timing Role: Primary-side rectifier sustaining continuous operation from –40°C to +70°C ambient. Use Value: –55°C to +150°C TJ range and JESD201 Class 2 whisker resistance ensure long-term reliability in vibration-prone control cabinets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | VRRM = 600V, trr = 35ns, VF = 1.15V @ 3A - faster but higher voltage rating | Better suited for 400V+ bus systems; over-spec'd for 200V designs requiring tighter cost control | Select when ultra-low trr and higher voltage margin justify premium pricing and footprint change |
| ON Semi MUR320 | VRRM = 200V, trr = 35ns, VF = 1.25V @ 3A - significantly faster recovery, same voltage class | Enables >500 kHz operation where FR303G R0G's 150ns limits switching frequency | Prefer for high-density, high-frequency SMPS where reduced EMI and loss outweigh DO-201AD lead-form constraints |
Compared with STTH3L06S and MUR320, FR303G R0G offers optimal balance of cost, proven reliability in 200V systems, and DO-201AD compatibility with legacy through-hole layouts - making it ideal for cost-sensitive industrial and consumer power supplies where 150ns trr meets timing requirements.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for FR303G R0G?
The FR303G R0G has a VRRM of 200 V, meaning it can reliably block up to 200 volts of reverse polarity voltage in repetitive operation. This rating is confirmed in the absolute maximum ratings table and applies across the full operating temperature range. Exceeding this voltage risks avalanche breakdown and permanent damage to the FR303G R0G.
What does the 'R0G' suffix indicate in FR303G R0G?
The 'R0G' suffix identifies the standard-grade, non-AEC-Q101 qualified version of the FR303G in DO-201AD package with green molding compound. It distinguishes this variant from AEC-Q101-qualified versions (e.g., FR303GH), which carry an 'H' suffix and undergo additional automotive stress testing. The FR303G R0G remains fully compatible in form, fit, and function with those variants.
Is FR303G R0G suitable for surface-mount reflow assembly?
Yes, FR303G R0G is qualified for surface-mount reflow assembly despite its DO-201AD axial package. Its pure tin-plated leads meet J-STD-002 solderability standards, and the UL 94V-0 molding compound withstands standard lead-free reflow profiles (peak ≤260°C). Thermal validation confirms no delamination or parametric shift after JEDEC J-STD-20D-compliant cycling.
What is the reverse recovery time (trr) test condition for FR303G R0G?
The FR303G R0G reverse recovery time is specified as 150 ns, measured under the condition: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the electrical specifications table. This test setup reflects realistic switching transitions in practical DC-DC converter circuits and is distinct from conditions used for FR305G (250 ns) or FR307G (500 ns).
How does FR303G R0G compare to FR302G and FR304G in voltage rating?
FR303G R0G is rated for 200 V VRRM, positioned between FR302G (100 V) and FR304G (400 V) in the FR30xG family. All share identical package (DO-201AD), forward current (3 A), and thermal specs, differing only in VRRM, VR(RMS), and trr. The FR303G R0G provides optimal voltage margin for 120VAC-derived 170VDC bus applications while maintaining fast 150 ns recovery.
