Product details
Overview
FR202GH from Taiwan Semiconductor is a 2A, 100V fast recovery rectifier diode in DO-204AC (DO-15) package, featuring glass passivated junction, 1.3V max forward voltage at 2A, 150ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as primary output rectifier in DC-DC converters and switching inverters.
For engineers reviewing the FR202GH datasheet, FR202GH pinout, FR202GH application, or FR202GH equivalent, key selection criteria include repetitive peak reverse voltage (100V), surge current rating (55A), thermal resistance (70°C/W), junction temperature range (–55°C to +150°C), and AEC-Q101 qualification status.
Technical Context
This single-die fast recovery rectifier uses a glass-passivated PN junction to achieve low forward voltage drop and controlled reverse recovery behavior. Its 150ns trr and 5µA max IR at 25°C support high-frequency switching topologies with reduced switching loss and EMI.
The device operates across –55°C to +150°C junction temperature, with 70°C/W junction-to-ambient thermal resistance enabling reliable 2A continuous conduction in standard PCB layouts without forced cooling.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the FR202GH?
The FR202GH has a VRRM rating of 100 V, meaning it can reliably block up to 100 volts of reverse voltage in repetitive operation. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2105). Exceeding this voltage risks avalanche breakdown and permanent damage to the FR202GH.
Is the FR202GH AEC-Q101 qualified, and what does that mean for automotive use?
Yes, the "H" suffix in FR202GH explicitly denotes AEC-Q101 qualification per Taiwan Semiconductor's ordering code table. This means the FR202GH has passed stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing-validating its suitability for automotive powertrain and body electronics where reliability under thermal and mechanical stress is mandatory.
What is the reverse recovery time (trr) of the FR202GH, and how does it affect switching performance?
The FR202GH has a reverse recovery time (trr) of 150 ns under standard test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A). This fast recovery minimizes switching losses and associated EMI in DC-DC converters operating up to ~500 kHz. The FR202GH's trr directly impacts efficiency and thermal design-slower diodes would increase dissipation and require larger heatsinks.
Can the FR202GH replace the FR201GH or FR203GH in an existing design?
No-FR202GH is not a direct replacement for FR201GH (50V VRRM) or FR203GH (200V VRRM) due to differing voltage ratings. Substituting FR202GH in a circuit designed for FR203GH risks insufficient reverse blocking; using it where FR201GH is specified may over-specify voltage margin. Always verify VRRM, trr, and VF alignment before interchanging any FR20xGH variant.
What package type and lead finish does the FR202GH use?
The FR202GH uses the DO-204AC (DO-15) axial-leaded package with pure tin-plated leads compliant with J-STD-002 solderability standards. Its marking includes "FR202G" and a cathode band. The molding compound meets UL 94V-0 flammability rating, and the device weighs approximately 0.400 g-critical for automated placement and thermal modeling of the FR202GH.
