Product details
Overview
F1T5G from Taiwan Semiconductor is a 1 A, 600 V fast recovery rectifier diode in TS-1 package, featuring 250 ns reverse recovery time, 1.3 V max forward voltage at 1 A, and 5 µA max reverse leakage at 25°C. It serves as a primary output rectifier in high-frequency DC-DC converters for industrial power supplies.
For engineers reviewing the F1T5G datasheet, F1T5G pinout, F1T5G application, or F1T5G equivalent, key selection criteria include its 600 V VRRM, TS-1 thermal resistance of 90 °C/W, AEC-Q101 qualification option (F1T5GH), and compatibility with automated SMT assembly due to pure tin-plated leads.
Technical Context
The F1T5G employs a single-die, glass-passivated PN junction optimized for fast switching in hard-commutated topologies. Its 250 ns trr and low 15 pF junction capacitance enable efficient operation up to several hundred kHz in flyback and forward converters.
Thermally, the TS-1 package delivers 90 °C/W junction-to-ambient resistance under standard JEDEC conditions, supporting continuous 1 A conduction at ambient temperatures up to 85°C with minimal heatsinking. The cathode band marking ensures unambiguous polarity identification during placement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking voltage; defines usable input voltage range in offline or high-bus applications |
| IF | 1 A - Continuous average forward current; sets maximum steady-state power delivery capability |
| trr | 250 ns - Measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; determines switching loss and EMI profile |
| VF (max) | 1.3 V @ 1 A, 25°C - Directly impacts conduction loss and thermal rise in high-duty-cycle operation |
| IR (max) | 5 µA @ 25°C - Low leakage preserves efficiency in high-impedance hold-up or sensing circuits |
| RθJA | 90 °C/W - Enables thermal design without forced air or heatsink in compact 5–10 W power stages |
| Junction temp | −55°C to +150°C - Supports operation in automotive under-hood or industrial control environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | Same 1 A / 600 V rating; trr = 200 ns (slightly faster); VF = 1.35 V (slightly higher) | Optimized for ST's proprietary Si process; widely used in consumer adapters | Prefer when tighter trr tolerance (<200 ns) is required and VF increase is acceptable |
| ES1J | 1 A / 600 V; trr = 35 ns (much faster); VF = 1.7 V (higher conduction loss) | Ultrafast category; suited for >1 MHz resonant topologies but less efficient at 100–300 kHz | Choose only if system operates above 500 kHz and thermal budget permits higher VF |
Compared with STTH1R06 and ES1J, the F1T5G offers the best balance of low VF (1.3 V), moderate trr (250 ns), and TS-1 package thermal performance (90 °C/W), making it optimal for cost-sensitive, thermally constrained 100–300 kHz industrial power supplies.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the F1T5G?
The F1T5G has a VRRM of 600 V, as confirmed in the Absolute Maximum Ratings table across all versions (H2104). This value is fixed for the F1T5G variant and distinguishes it from adjacent members (e.g., F1T4G = 400 V, F1T6G = 800 V). The F1T5G must not be subjected to reverse voltages exceeding this rating in continuous operation.
Does the F1T5G have AEC-Q101 qualification?
The base F1T5G is not AEC-Q101 qualified; however, the F1T5GH variant-identical in electrical and thermal specs-is explicitly qualified per AEC-Q101. The "H" suffix denotes qualification, and both parts share the same TS-1 package, marking code (F1T5G), and ordering structure per the datasheet's Ordering Information table.
What is the reverse recovery time (trr) of the F1T5G and under what test conditions?
The F1T5G has a trr of 250 ns, measured under the condition: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, per the Electrical Specifications table on page 2 of the H2104 datasheet. This value is specific to F1T5G and differs from F1T1G–F1T4G (150 ns) and F1T6G–F1T7G (500 ns).
Can the F1T5G replace the F1T4G or F1T6G in an existing design?
No direct substitution is recommended. The F1T5G (600 V) sits between F1T4G (400 V) and F1T6G (800 V); replacing either requires verifying that operating reverse voltage remains within 600 V for F1T5G or ≥800 V for F1T6G. Thermal and switching behavior also differ-F1T5G's 250 ns trr is slower than F1T4G's 150 ns, potentially increasing EMI in high-frequency designs.
What packaging options are available for the F1T5G?
The F1T5G is supplied in TS-1 package with two standard packing formats: 5,000 units per tape-and-reel (ordering code F1T5G) and 3,000 units per ammo box (ordering code F1T5GA0G). Both use pure tin-plated leads and meet J-STD-002 solderability requirements, supporting reflow and wave soldering processes.
