Product details
Overview
SF1606G from Taiwan Semiconductor is a 16A, 400V super fast recovery rectifier diode in TO-220AB package, featuring 35ns reverse recovery time, 1.300V forward voltage at 8A/25°C, and 125A surge current capability; used in switching mode power supplies and freewheeling paths where fast switching and low conduction loss are required.
For engineers reviewing the SF1606G datasheet, SF1606G pinout, SF1606G application, or SF1606G equivalent, key selection factors include its 400V VRRM, dual-die TO-220AB configuration, AEC-Q101 qualification option (SF1606GH), thermal resistance of 1.5°C/W, and junction temperature range of –55°C to +150°C.
Technical Context
The SF1606G is a single-phase, dual-die super fast rectifier optimized for high-frequency switching applications. Its 35ns trr and 60pF junction capacitance per diode enable efficient operation in DC–DC converters and inverters operating up to several hundred kHz.
Designed with matte tin-plated leads compliant with J-STD-002 and meeting JESD201 Class 2 whisker resistance, the device supports automated soldering and automotive-grade reliability when ordered as SF1606GH. The TO-220AB case provides mechanical robustness and direct heatsink mounting capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse voltage; defines safe blocking capability in 400V-rated power rails |
| IF | 16 A - Continuous forward current rating; determines steady-state power handling without derating below 75°C case temp |
| IFSM | 125 A - Non-repetitive surge current (8.3ms half-sine); supports inrush and fault-current tolerance |
| VF | 1.300 V @ 8A, 25°C - Low conduction loss per diode; reduces power dissipation in high-duty-cycle rectification |
| trr | 35 ns - Fast reverse recovery; minimizes switching losses and EMI in high-frequency SMPS topologies |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance; enables ~10W dissipation with ≤15°C rise above heatsink |
| CJ | 60 pF @ 1MHz, 4V - Low junction capacitance; limits displacement current and improves high-speed turn-off behavior |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1604TV1 | 16A, 400V, 30ns trr, TO-220AC package (single anode), RθJC = 1.7°C/W | No dual-die configuration; requires two devices for same functionality as SF1606G | Select when single-diode layout or STMicroelectronics supply chain preference applies |
| VS-16EWH04-M3 | 16A, 400V, 35ns trr, TO-220AB, AEC-Q101 qualified, VF = 1.32V @ 8A | Identical dual-die TO-220AB pinout and thermal specs; slightly higher VF increases conduction loss by ~1.5% | Preferred for automotive programs requiring guaranteed AEC-Q101 compliance out-of-box |
Compared with STTH1604TV1 and VS-16EWH04-M3, the SF1606G offers identical trr and package but lower VF than the latter and integrated dual-die convenience over the former-making it optimal for space-constrained, high-efficiency industrial SMPS where cost-per-function and layout simplicity matter.

FAQ
What is the maximum junction temperature rating for SF1606G?
The SF1606G has a maximum junction temperature (TJ) of +150°C and a minimum of –55°C. This rating is specified across the full operating range and validated per JEDEC standards. Derating curves in the official datasheet show that continuous 16A forward current is sustainable only when case temperature remains ≤75°C. At higher ambient temperatures, thermal design must ensure junction temperature stays within this limit to prevent parametric shift or failure.
Does SF1606G have AEC-Q101 qualification?
The base SF1606G is not AEC-Q101 qualified; however, the variant SF1606GH is fully qualified per AEC-Q101 Rev D for stress testing including HTSL, TCT, and H3TRB. The "H" suffix denotes automotive qualification, and both versions share identical electrical and thermal specifications. Engineers selecting for automotive applications must specify SF1606GH to meet OEM component approval requirements.
What is the pin configuration of SF1606G in TO-220AB package?
The SF1606G uses a standard TO-220AB 3-pin configuration with Anode 1 on Pin 1 (left), common Cathode on Pin 2 (center), and Anode 2 on Pin 3 (right) when viewed with marking side up and leads down. This dual-anode, single-cathode arrangement supports center-tapped transformer outputs or dual-channel rectification without external parallel diodes. Mounting torque must not exceed 0.56 N·m to avoid package damage.
How does SF1606G compare to SF1604G in terms of forward voltage and application suitability?
SF1606G specifies 1.300V VF at 8A/25°C, while SF1604G (200V version) specifies 0.975V under identical conditions. The higher VF reflects optimized carrier lifetime for 400V blocking, making SF1606G better suited for 400V bus applications like PV string inverters or industrial 380V AC–DC front ends, whereas SF1604G is preferred in lower-voltage, ultra-low-loss 200V systems such as telecom rectifiers.
Is SF1606G halogen-free and RoHS compliant?
Yes, SF1606G is both RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated or chlorinated flame retardants, and lead content is below 1000 ppm. These compliance attributes are verified through material declarations and third-party lab testing, supporting use in consumer electronics, medical peripherals, and EU-market industrial equipment where substance restrictions apply.
