Product details
Overview
FR306GH from Taiwan Semiconductor is a 3A, 800V fast recovery rectifier diode in DO-201AD package, featuring 500 ns reverse recovery time, 1.3 V forward voltage at 3 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the FR306GH datasheet, FR306GH pinout, FR306GH application, or FR306GH equivalent, key selection criteria include repetitive peak reverse voltage (800 V), surge current capability (125 A), thermal resistance (35 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance.
Technical Context
This single-die, through-hole fast recovery rectifier supports high-frequency switching in power conversion stages. Its 500 ns trr enables efficient operation in SMPS and DC-DC converters up to several hundred kHz, while the 800 V VRRM rating targets mid-voltage industrial and automotive auxiliary power rails.
The device uses pure tin-plated leads compliant with J-STD-002 and passes JESD201 Class 2 whisker testing. Thermal performance is defined by a 35 °C/W junction-to-ambient resistance under standard mounting conditions on FR-4 PCB with 1-inch² copper pad.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for FR306GH?
The FR306GH has a VRRM rating of 800 V, meaning it can reliably block up to 800 volts of reverse voltage in repetitive operation without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2105), and applies across the full operating temperature range of –55 °C to +150 °C. The FR306GH is part of the FR301G–FR307G family where "6" denotes the 800 V grade.
Is FR306GH AEC-Q101 qualified, and what does that mean for design use?
Yes, FR306GH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the Features section of the datasheet. This qualification validates its suitability for automotive electronic modules-including engine control units, body controllers, and ADAS power supplies-where reliability under thermal cycling, mechanical shock, and humidity is mandatory. FR306GH meets all stress tests defined in the AEC-Q101 standard.
What is the reverse recovery time (trr) of FR306GH, and how does it compare to other devices in the FR30xG series?
The FR306GH has a reverse recovery time (trr) of 500 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. Within the FR301G–FR307G family, this trr value is shared only with FR307GH (1000 V grade); lower-voltage variants like FR304GH have trr ≤ 150 ns. The 500 ns figure reflects optimized carrier lifetime control for balanced speed and softness in 800–1000 V applications.
Does FR306GH have halogen-free and RoHS-compliant construction?
Yes, FR306GH is both RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the Features section of the official datasheet. The molding compound is UL 94V-0 rated, and the pure tin-plated leads meet J-STD-002 solderability requirements. These attributes make FR306GH suitable for consumer, industrial, and automotive applications subject to strict environmental regulations in EU, China, and North America.
What is the thermal resistance (RθJA) of FR306GH, and how should it be used in thermal design?
The junction-to-ambient thermal resistance (RθJA) of FR306GH is 35 °C/W, specified under standard test conditions (JEDEC 51-2, 1-inch² copper pad on FR-4). This value enables estimation of junction temperature rise: TJ = TA + (Pd × 35). For example, at 2 W dissipation and 75 °C ambient, TJ ≈ 145 °C-within the +150 °C maximum limit. Layout optimization (e.g., added copper area) can further reduce effective RθJA in production designs.
