Product details
Overview
FR206GH from Taiwan Semiconductor is an AEC-Q101-qualified fast recovery rectifier diode in DO-204AC (DO-15) package, rated for 800 V repetitive peak reverse voltage (VRRM), 2 A average forward current (IF), and 55 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (VF ≤ 1.3 V at 2 A, 25°C), 500 ns reverse recovery time (trr), and operates up to 150°C junction temperature - used in automotive-grade DC-DC converters and switching inverters.
For engineers reviewing the FR206GH datasheet, FR206GH pinout, FR206GH application, or FR206GH equivalent, key selection criteria include its AEC-Q101 qualification, 800 V VRRM rating, 500 ns trr performance, DO-15 mechanical compatibility, and thermal resistance of 70°C/W - critical for high-reliability power conversion designs.
Technical Context
This single-die, glass-passivated fast recovery rectifier uses a planar junction structure optimized for low conduction loss and controlled reverse recovery behavior. Its 500 ns trr and 10 pF junction capacitance (at 1 MHz, 4 V) support operation in medium-frequency switching topologies up to ~100 kHz.
The device features pure tin-plated leads compliant with J-STD-002 solderability, meets JESD201 Class 2 whisker resistance, and employs UL 94V-0 molding compound - confirming suitability for automotive under-hood and industrial power supply environments where thermal cycling and long-term reliability are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - supports input rectification in 400–600 VAC line-fed SMPS and automotive 48 V–400 V battery systems |
| IF | 2 A continuous - enables compact heat-sinkless designs in <10 W isolated flyback and <25 W non-isolated buck-derived converters |
| trr | 500 ns - limits switching losses and EMI generation in 20–100 kHz hard-switched converters |
| VF | ≤1.3 V at 2 A, 25°C - reduces conduction loss to <2.6 W at full load, easing thermal management |
| RθJA | 70 °C/W - allows ~25°C rise above ambient at 2 A in standard DO-15 PCB mount with 1 cm² copper pad |
| IFSM | 55 A (8.3 ms half-sine) - withstands inrush currents during cold-start of industrial motor drives and LED drivers |
| TJ max | 150 °C - supports operation in under-hood automotive locations without derating below 125°C ambient |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R08 | Same DO-15 package, 800 V VRRM, but trr = 75 ns (faster), VF = 1.7 V (higher), no AEC-Q101 qualification | Better suited for high-frequency SMPS (>200 kHz); not qualified for automotive use | Select STTH2R08 only when ultra-fast recovery outweighs VF penalty and AEC-Q101 is unnecessary |
| ON Semi MUR280E | DO-15, 800 V, trr = 60 ns, VF = 1.75 V, AEC-Q101 qualified, but IFSM = 50 A (lower than FR206GH's 55 A) | Valid for automotive, but lower surge tolerance limits use in high-inrush applications like motor drives | Prefer FR206GH over MUR280E when 55 A IFSM is required for robust cold-start performance |
Compared with STTH2R08 and MUR280E, FR206GH uniquely balances AEC-Q101 compliance, 55 A surge capability, and 500 ns trr - making it optimal for cost-sensitive, thermally constrained automotive and industrial converters where moderate speed and high ruggedness are prioritized.

FAQ
What is the maximum junction temperature rating for FR206GH?
The FR206GH has a maximum junction temperature (TJ max) of +150°C, verified per AEC-Q101 stress testing. This rating allows uninterrupted operation in under-hood automotive environments and high-ambient industrial enclosures. Derating begins above 25°C ambient per the forward current derating curve in the FR201G–FR207G datasheet, with 2 A IF maintained up to ~70°C ambient on standard PCB layout.
Is FR206GH pin-compatible with other DO-204AC rectifiers such as FR205G or FR207G?
Yes, FR206GH shares identical DO-204AC (DO-15) mechanical dimensions, lead spacing, and polarity marking (cathode band) with FR201G through FR207G. All variants use the same footprint and mounting method. However, electrical ratings differ - FR206GH is specifically rated for 800 V VRRM, unlike FR205G (600 V) or FR207G (1000 V) - so voltage margin must be re-verified in circuit design.
Does FR206GH require heatsinking in typical 2 A applications?
In most 2 A continuous applications with standard PCB layout (≥1 cm² copper pour per lead), FR206GH does not require external heatsinking due to its 70°C/W junction-to-ambient thermal resistance and low VF (≤1.3 V). Temperature rise remains within safe limits (<50°C) at 25°C ambient. For sustained 2 A operation above 70°C ambient or in enclosed spaces, localized copper thermal relief or minimal heatsink attachment is recommended.
What does the "H" suffix in FR206GH signify?
Per Taiwan Semiconductor's ordering information, the "H" suffix in FR206GH denotes AEC-Q101 qualification - confirming that the device has passed stress tests for automotive-grade reliability, including temperature cycling, humidity bias HAST, and high-temperature operating life. This distinguishes FR206GH from the non-qualified FR206G variant and validates its use in automotive power modules and ADAS subsystems.
How does the reverse recovery time (trr) of FR206GH impact EMI in switching converters?
With a specified trr of 500 ns, FR206GH generates moderate reverse recovery current spikes during turn-off, contributing to high-frequency ringing (20–100 MHz) in hard-switched topologies. This necessitates careful snubber design and layout optimization - especially gate loop area minimization and ground plane integrity - to suppress conducted EMI. Its trr is intentionally balanced against VF to limit total loss, making it less EMI-sensitive than ultrafast diodes but more controllable than standard recovery types.
