Product details
Overview
FR201GH from Taiwan Semiconductor is a 2A, 50V fast recovery rectifier diode in DO-204AC (DO-15) package, featuring glass passivated junction, 1.3V max forward voltage at 2A, 55A surge capability, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the FR201GH datasheet, FR201GH pinout, FR201GH application, or FR201GH equivalent, key selection factors include its 50V repetitive peak reverse voltage, 150ns reverse recovery time, low 5µA reverse leakage at 25°C, and suitability for compact DC-DC converters requiring high efficiency and thermal robustness.
Technical Context
This single-die fast recovery rectifier uses a glass-passivated PN junction to achieve low forward voltage drop and stable switching performance under transient load conditions. Its 150ns trr and 70°C/W junction-to-ambient thermal resistance support high-frequency operation in space-constrained power stages.
The device operates across –55°C to +150°C junction temperature range and delivers 2A average forward current with 55A non-repetitive surge rating. It meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements for industrial and automotive PCB environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | 600V VRRM, 1.7V VF @ 2A, TO-220AC package | Higher voltage rating but larger footprint and higher conduction loss | Prefer when system requires >100V reverse blocking or higher surge margin |
| ON Semi MUR220 | 200V VRRM, 1.25V VF @ 2A, DO-15 package, non-AEC-Q101 | Same form factor and lower VF, but lacks automotive qualification and has higher trr (35ns vs. 150ns) | Acceptable for cost-sensitive industrial adapters where AEC-Q101 is not mandated |
Compared with STTH2R06 and MUR220, FR201GH uniquely balances 50V rating, AEC-Q101 compliance, DO-15 footprint, and 150ns trr-making it optimal for space-limited, thermally constrained automotive DC-DC stages where precise voltage matching and qualification matter more than raw surge margin or ultra-low VF.

FAQ
What is the maximum junction temperature rating for FR201GH?
The FR201GH has a maximum junction temperature (TJ MAX) of +150°C, verified per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive environments and sealed industrial enclosures. Derating begins at 25°C ambient, with full 2A current supported up to 70°C ambient when mounted on standard FR-4 PCB with 1-inch² copper pour. FR201GH must not exceed 150°C junction temperature during transient or steady-state conditions.
Is FR201GH pin-compatible with standard DO-15 rectifiers like 1N4007?
Yes, FR201GH uses the DO-204AC (DO-15) package with identical mechanical dimensions and axial lead configuration as 1N4007, enabling direct PCB footprint reuse. However, FR201GH is a fast recovery device (150ns trr) versus 1N4007's 30µs recovery, making it unsuitable for line-frequency applications but ideal for high-frequency SMPS. The cathode band orientation matches industry-standard DO-15 polarity marking.
Does FR201GH require a heatsink in typical 2A applications?
FR201GH typically does not require an external heatsink when operating at ≤2A DC current in still air, due to its 70°C/W RθJA and low 1.3V VF. At 2A and 25°C ambient, calculated junction temperature rise is ~182°C - exceeding rating - so practical use assumes ≥1-inch² copper pad and ≤70°C ambient. For sustained 2A loads above 60°C ambient, a small copper thermal pad or minimal finned heatsink is recommended. FR201GH's thermal design relies on PCB copper area, not added hardware.
What does the "H" suffix in FR201GH signify?
The "H" suffix in FR201GH indicates full AEC-Q101 qualification per Rev D test requirements, including stress tests for temperature cycling, high-temperature operating life, unbiased highly accelerated stress test (uHAST), and electrostatic discharge. This distinguishes FR201GH from non-H variants (e.g., FR201G), which lack automotive qualification documentation and test reports. FR201GH is certified for use in automotive powertrain, body control, and ADAS subsystems.
How does FR201GH's reverse recovery time affect EMI in switching converters?
FR201GH's 150ns reverse recovery time limits high-frequency ringing during turn-off, reducing broadband EMI generation compared to standard recovery diodes. In 200kHz flyback designs, this results in measurable attenuation of 10–30MHz noise peaks at the transformer secondary. Combined with low 10pF junction capacitance, FR201GH enables cleaner output filtering and reduced common-mode choke size. EMI performance is further enhanced by its glass-passivated junction stability under thermal cycling.
