Product details
Overview
FR202G from Taiwan Semiconductor is a 2A, 100V fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 150 ns reverse recovery time, 1.3 V max forward voltage at 2 A, and 55 A surge current capability - used in switching mode power supplies and DC-DC converters.
For engineers reviewing the FR202G datasheet, FR202G pinout, FR202G application, or FR202G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), thermal resistance (70 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification availability for automotive-grade variants.
Technical Context
This single-die, glass-passivated fast recovery rectifier employs planar epitaxial construction to achieve low forward voltage drop and controlled reverse recovery behavior. Its 150 ns trr and 10 pF junction capacitance support high-frequency switching up to several hundred kHz in SMPS topologies.
The device operates across –55 °C to +150 °C junction temperature, with 70 °C/W junction-to-ambient thermal resistance enabling reliable 2 A continuous conduction in standard PCB layouts without forced air cooling under typical ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling paths |
| IF | 2 A - average forward current rating; supports continuous conduction in 20–50 W power stages |
| trr | 150 ns - reverse recovery time; enables efficient operation in 100–500 kHz switching converters |
| VF (max) | 1.3 V @ 2 A, 25°C - forward voltage drop directly impacts conduction loss and thermal design |
| IFSM | 55 A - non-repetitive surge current; withstands inrush and fault transients in AC-input rectification |
| RθJA | 70 °C/W - thermal resistance; determines required copper area and ambient derating for 2 A operation |
| IR (max) | 5 µA @ 25°C - reverse leakage; critical for low-power standby and high-impedance sensing circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R01 | 100 V VRRM, 2 A IF, 125 ns trr, TO-220AC package | Higher thermal mass but requires heatsink; not DO-15 drop-in | Preferred when higher surge robustness and board-level thermal management are prioritized over footprint |
| ES2D | 200 V VRRM, 2 A IF, 35 ns trr, SMA package | Smaller surface-mount footprint; faster recovery but higher VF (~1.55 V) | Selected for space-constrained designs needing ultra-fast switching, accepting higher conduction loss |
Compared with STTH2R01 and ES2D, the FR202G offers optimal balance of axial-lead manufacturability, 150 ns trr, and 1.3 V VF in cost-sensitive through-hole power supplies - especially where AEC-Q101 compliance is optional but thermal derating headroom is needed.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for FR202G?
The FR202G has a VRRM rating of 100 V, meaning it can safely block up to 100 V of reverse voltage repeatedly in circuit operation. This value is fixed per the FR202G designation within the FR201G–FR207G family and is confirmed in the Absolute Maximum Ratings table. Exceeding this voltage risks avalanche breakdown and permanent damage to the FR202G.
Does FR202G have AEC-Q101 qualification?
The base FR202G part is not AEC-Q101 qualified; however, the variant FR202GH (with 'H' suffix) is explicitly qualified per AEC-Q101. The FR202G datasheet notes AEC-Q101 availability for the family, but qualification applies only to marked 'H' versions. Always verify the full ordering code - FR202G vs. FR202GH - when designing for automotive applications requiring stress-tested components.
What is the reverse recovery time (trr) of FR202G and how is it measured?
The FR202G has a reverse recovery time (trr) of 150 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the Electrical Specifications table. This parameter reflects the time required for the diode to transition from forward conduction to reverse blocking state, directly impacting switching loss and EMI in high-frequency power converters using the FR202G.
Can FR202G replace FR201G in an existing design?
Yes, FR202G can replace FR201G mechanically and electrically: both share identical DO-204AC (DO-15) package, 2 A IF rating, and 55 A IFSM. The only difference is VRRM - FR201G is 50 V, FR202G is 100 V - so FR202G offers higher reverse voltage margin without layout change. The FR202G maintains same VF, trr, and thermal performance, making it a safe upgrade in most FR201G applications.
What is the junction-to-ambient thermal resistance (RθJA) of FR202G?
The FR202G has a typical junction-to-ambient thermal resistance (RθJA) of 70 °C/W when mounted on a standard FR-4 PCB with minimum copper pad area (as defined in JEDEC test condition). This value assumes no heatsink and natural convection; actual RθJA improves with larger copper pours. Designers must use this RθJA to calculate junction temperature rise under 2 A load and ensure TJ remains ≤150 °C for reliable FR202G operation.
