Product details

Overview

SFT16G from Taiwan Semiconductor is a 1 A, 400 V repetitive peak reverse voltage super fast rectifier diode in TS-1 package, featuring 35 ns reverse recovery time, 1.30 V forward voltage at 1 A and 25°C, and 100°C/W junction-to-ambient thermal resistance-used in DC-DC converters and switching-mode inverters requiring fast recovery and low conduction loss.

For engineers reviewing the SFT16G datasheet, SFT16G pinout, SFT16G application, or SFT16G equivalent, key selection criteria include V_RRM = 400 V, I_F = 1 A, t_rr = 35 ns, V_F = 1.30 V, and TS-1 package compatibility with high-reliability power conversion designs.

Technical Context

The SFT16G is a single-die, planar passivated silicon super fast rectifier optimized for high-frequency switching applications. It delivers low forward voltage drop and fast reverse recovery to minimize switching losses in SMPS and freewheeling paths.

Its TS-1 package supports surface-mount assembly with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance, while the cathode band provides unambiguous polarity identification.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R04	V_RRM = 400 V, t_rr = 30 ns, V_F = 1.35 V @ 1 A - slightly faster but higher V_F	Same TS-1 footprint; used in ST reference designs for 200–300 kHz PFC stages	Prefer when <30 ns t_rr is critical and 0.05 V higher V_F is acceptable
ON Semi MUR1040	V_RRM = 400 V, t_rr = 50 ns, V_F = 1.25 V @ 1 A - slower but lower V_F	TO-220AC package; requires through-hole mounting and heatsinking for >0.7 A	Select only if board layout allows TO-220 and lower conduction loss outweighs slower recovery

Compared with STTH1R04 and MUR1040, the SFT16G offers balanced trade-off between recovery speed (35 ns), forward drop (1.30 V), and surface-mount TS-1 packaging-making it optimal for space-constrained, medium-frequency SMPS where thermal and EMI constraints coexist.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the SFT16G?

The SFT16G has a V_RRM of 400 V, verified per Taiwan Semiconductor's official datasheet Version J2104. This rating ensures reliable blocking of reverse voltage transients in 230 V AC-derived DC bus applications and flyback transformer secondary circuits. Exceeding 400 V risks avalanche breakdown and permanent device failure. The SFT16G must be derated per the forward current derating curve above 75°C ambient.

What is the forward voltage (V_F) of the SFT16G at rated current?

The SFT16G exhibits a typical forward voltage of 1.30 V at 1 A and 25°C junction temperature, as specified in the Electrical Specifications table. This value increases with temperature and current-reaching ~1.45 V at 1 A and 125°C. The SFT16G's V_F is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects during test.

Does the SFT16G have AEC-Q101 qualification?

The base SFT16G is not AEC-Q101 qualified; however, the SFT16GH variant-identical in electrical specs and TS-1 packaging-is explicitly qualified per AEC-Q101 Rev D for automotive underhood applications. The "H" suffix denotes qualification, including stress testing for temperature cycling, humidity, and mechanical shock. Customers requiring automotive-grade assurance must specify SFT16GH.

What is the reverse recovery time (t_rr) of the SFT16G and how is it tested?

The SFT16G has a maximum reverse recovery time of 35 ns, measured under defined conditions: I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A, per Figure 6 test circuit in the datasheet. This parameter reflects minority-carrier lifetime control in the epitaxial layer and directly impacts switching loss in hard-switched topologies. Values are guaranteed across the full -55°C to +150°C junction temperature range.

What package type does the SFT16G use and what are its key mechanical features?

The SFT16G uses the TS-1 surface-mount package: a compact, leadless outline with pure tin-plated terminations compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band; the molding compound meets UL 94V-0 flammability rating. Its 0.200 g mass and standardized footprint enable automated placement and reflow compatibility with IPC-A-610 Class 2/3 processes.
