Product details

Overview

F1T6GH from Taiwan Semiconductor is an AEC-Q101-qualified fast recovery rectifier diode in TS-1 package, rated for 800 V repetitive peak reverse voltage (V_RRM), 1 A average forward current (I_F), and 30 A non-repetitive surge current (I_FSM). It delivers low forward voltage (1.3 V max at 1 A, 25°C) and 500 ns reverse recovery time (t_rr), enabling high-efficiency operation in automotive DC-DC converters.

For engineers reviewing the F1T6GH datasheet, F1T6GH pinout, F1T6GH application, or F1T6GH equivalent, key selection criteria include its AEC-Q101 qualification, TS-1 surface-mount compatibility, 800 V blocking capability, 500 ns t_rr, and glass-passivated junction for reliability in harsh environments.

Technical Context

The F1T6GH employs a single-die, planar-glass-passivated silicon PN junction optimized for fast switching with controlled minority-carrier lifetime. Its 500 ns reverse recovery time is measured under standardized conditions (I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A), confirming suitability for medium-frequency switching applications up to ~100 kHz.

Thermal performance is defined by a junction-to-ambient thermal resistance of 90 °C/W (R_θJA) in standard mounting conditions, and it operates across –55°C to +150°C junction temperature range. The device features pure tin-plated leads compliant with J-STD-002 and JESD201 Class 2 whisker testing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast recovery rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R08	Same 800 V V_RRM, 1 A I_F, but t_rr = 75 ns; TO-220AC package	Requires through-hole PCB layout and heatsinking; not AEC-Q101 qualified	Select when ultra-fast recovery (<100 ns) is critical and surface-mount is not required
ON Semi MUR108	800 V V_RRM, 1 A I_F, t_rr = 75 ns; same TS-1 package but no AEC-Q101 certification	Lacks automotive qualification; higher V_F (1.7 V typ) increases conduction loss	Choose for cost-sensitive industrial applications where AEC-Q101 is unnecessary

Compared with STTH1R08 and MUR108, the F1T6GH trades ultra-fast recovery for automotive-grade reliability and surface-mount compatibility-making it optimal for space-constrained, high-reliability 48 V automotive systems where 500 ns t_rr suffices.

FAQ

What is the maximum junction temperature rating for F1T6GH?

The F1T6GH has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves confirm usable current capacity down to 0.5 A at 125°C ambient with standard PCB layout. The F1T6GH must be operated within this limit to maintain long-term reliability and AEC-Q101 qualification integrity.

Is F1T6GH pin-compatible with other devices in the F1T1G–F1T7G series?

Yes, all F1T1G–F1T7G variants-including F1T6GH-share identical TS-1 package dimensions, pinout (anode/cathode), and mechanical footprint. Voltage ratings differ only in internal die design; no PCB layout change is needed when upgrading or downgrading within the series. The "H" suffix in F1T6GH denotes AEC-Q101 qualification, but physical compatibility remains consistent across the family.

What does the "H" suffix in F1T6GH signify?

The "H" suffix in F1T6GH indicates full AEC-Q101 qualification, covering stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and high-temperature reverse bias (HTRB). This distinguishes F1T6GH from standard F1T6G, which shares electrical specs but lacks automotive validation. The F1T6GH is intended for safety-critical automotive subsystems where component-level reliability is mandated.

What is the reverse recovery time (t_rr) of F1T6GH, and under what conditions is it specified?

The F1T6GH has a reverse recovery time (t_rr) of 500 ns, measured under the condition I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A per the datasheet's Electrical Specifications table. This value reflects performance in medium-frequency switching applications and is validated using the test circuit shown in Figure 6 of the F1T1G–F1T7G datasheet. It is not characterized for zero-current-switching or resonant topologies.

Does F1T6GH meet halogen-free and RoHS requirements?

Yes, the F1T6GH complies with both RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21. The molding compound contains no brominated or chlorinated flame retardants, and terminal plating uses pure tin without lead, antimony, or bismuth additives. These specifications are confirmed in the Mechanical Data and Ordering Information sections of the official F1T1G–F1T7G datasheet revision H2104.
