Product details
Overview
SF16G from Taiwan Semiconductor is a 400 V, 1 A super fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 35 ns reverse recovery time, 1.30 V forward voltage at 1 A/25°C, and 30 A surge current capability; used in switching-mode power supplies and freewheeling paths where low conduction loss and fast switching are required.
For engineers reviewing the SF16G datasheet, SF16G pinout, SF16G application, or SF16G equivalent, key selection criteria include peak reverse voltage rating (400 V), forward voltage drop under load, thermal resistance (20 °C/W junction-to-lead), reverse recovery performance, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
The SF16G is a single-die, planar passivated silicon rectifier optimized for high-frequency switching applications. Its 35 ns trr and low CJ (10 pF at 1 MHz, 4 V) support efficient operation in DC–DC converters and inverters up to several hundred kHz.
Rated for TJ = –55°C to +150°C and qualified to AEC-Q101 (when marked with 'H' suffix), it delivers stable reverse leakage (<5 µA at 25°C, <100 µA at 125°C) and robust surge handling (30 A IFSM, 8.3 ms half-sine) in industrial and automotive power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse voltage the device blocks reliably in circuit |
| IF | 1 A - Continuous average forward current rating at TA = 75°C (derated above) |

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 (STMicroelectronics) | Same VRRM (400 V), IF (1 A), but VF = 1.35 V (typ), trr = 30 ns, DO-41 package | Marginally faster recovery but higher VF; not AEC-Q101 qualified | Preferred where minimal trr dominates over conduction loss; verify thermal margin due to higher VF |
| ES1D (ON Semiconductor) | VRRM = 200 V (lower), IF = 1 A, VF = 1.7 V (max), trr = 35 ns, same DO-41 package | Not suitable for 400 V bus applications; limited to ≤200 V systems | Select only for cost-sensitive 200 V designs; insufficient voltage margin for SF16G's 400 V use cases |
Compared with STTH1R04 and ES1D, the SF16G offers optimal balance of 400 V rating, 1.30 V VF, and AEC-Q101 availability-making it uniquely suited for automotive and industrial 400 V rectification where both voltage margin and thermal efficiency are critical.

FAQ
What is the peak repetitive reverse voltage rating of the SF16G?
The SF16G has a peak repetitive reverse voltage (VRRM) rating of 400 V. This means it can reliably block up to 400 V in reverse-biased operation under repetitive conditions without breakdown. The rating is confirmed in the Absolute Maximum Ratings table on page 1 of the H2104 datasheet and applies across the full operating temperature range (–55°C to +150°C).
What is the forward voltage drop of the SF16G at rated current?
The SF16G exhibits a maximum forward voltage (VF) of 1.30 V at 1 A forward current and 25°C junction temperature. This value is measured under pulsed conditions (PW = 0.3 ms) and represents the conduction loss that directly affects system efficiency and thermal design. At higher temperatures, VF decreases slightly due to negative temperature coefficient of silicon.
Is the SF16G suitable for automotive applications?
The SF16G itself is not AEC-Q101 qualified; however, its variant SF16GH is explicitly qualified to AEC-Q101. The base SF16G shares identical electrical and thermal specifications but lacks the extended stress testing required for automotive use. For automotive designs, specify SF16GH to ensure compliance with temperature cycling, humidity, and mechanical shock requirements.
What is the reverse recovery time of the SF16G and how is it tested?
The SF16G has a maximum reverse recovery time (trr) of 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This test uses a standardized double-pulse method defined in JEDEC standards to quantify switching speed. The low trr enables efficient operation in high-frequency switching power supplies while minimizing switching losses and associated EMI.
What package type does the SF16G use and what are its key mechanical features?
The SF16G uses the DO-204AL (DO-41) axial-leaded package. Key mechanical features include pure tin-plated leads compliant with J-STD-002, UL 94V-0 flammability-rated molding compound, cathode polarity indicated by a visible band, and a typical weight of 0.350 g. The package supports manual and automated assembly and meets JESD201 Class 2 whisker resistance.
How does the SF16G compare to the SF15G and SF17G in terms of voltage and forward voltage?
The SF16G is rated for 400 V VRRM and has VF = 1.30 V (max) at 1 A/25°C. In comparison, SF15G is 300 V / 1.30 V, and SF17G is 500 V / 1.70 V. Thus, SF16G provides the optimal 400 V rating for common intermediate bus voltages while maintaining the same VF as SF15G-offering better voltage margin than SF15G without the higher conduction loss of SF17G.
