Product details
Overview
SF1603G from Taiwan Semiconductor is a 150 V, 16 A super fast recovery rectifier diode in TO-220AB package, featuring 35 ns reverse recovery time, 0.975 V forward voltage at 8 A and 25 °C, and 1.5 °C/W junction-to-case thermal resistance. It serves as a primary output rectifier in high-frequency DC/DC converters requiring low conduction loss and fast switching.
For engineers reviewing the SF1603G datasheet, SF1603G pinout, SF1603G application, or SF1603G equivalent, key selection criteria include its 150 V repetitive peak reverse voltage, dual-die configuration for enhanced surge capability, AEC-Q101 qualification option (SF1603GH), and compatibility with automated through-hole assembly due to matte tin-plated leads.
Technical Context
The SF1603G employs a planar epitaxial super fast recovery structure optimized for switching-mode power supplies operating above 50 kHz. Its 35 ns trr and low 80 pF junction capacitance per diode minimize switching losses and EMI generation during turn-off transitions.
Designed with dual dies in a single TO-220AB package, the device supports symmetrical current sharing and delivers 125 A non-repetitive surge current (8.3 ms half-sine) while maintaining TJ ≤ 150 °C under rated DC load and RθJC = 1.5 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling paths |
| IF | 16 A - continuous forward current rating at TC = 100 °C; determines heatsink sizing for steady-state operation |
| IFSM | 125 A - peak surge current handling for 8.3 ms; enables robustness against line transients and startup inrush |
| trr | 35 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; critical for minimizing switching loss in >100 kHz converters |
| VF | 0.975 V - forward voltage drop per diode at IF = 8 A, TJ = 25 °C; directly impacts conduction loss and thermal design |
| CJ | 80 pF - junction capacitance per diode at 1 MHz, VR = 4.0 V; affects high-frequency noise coupling and snubber design |
| RθJC | 1.5 °C/W - thermal resistance from junction to case; enables accurate temperature rise prediction with mechanical mounting data |
Pinout & Package
TO-220AB package with center tab (cathode), two anode leads (dual-die configuration), matte tin-plated terminals compliant with J-STD-002 solderability, and polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602CT | 100 V VRRM, single-die TO-220AC, 30 ns trr, 1.05 V VF @ 8 A | Limited to ≤100 V systems; lacks dual-anode flexibility and AEC-Q101 option | Select when lower voltage rating suffices and dual-die functionality is unnecessary |
| ON Semiconductor MUR1620CT | 200 V VRRM, single-die TO-220AC, 60 ns trr, 1.1 V VF @ 8 A | Higher VRRM but slower recovery and higher VF increase switching/conduction loss in 150 V designs | Choose only if 200 V margin is mandatory and 25 ns trr penalty is acceptable |
Compared with STTH1602CT and MUR1620CT, the SF1603G uniquely combines 150 V rating, 35 ns trr, dual-anode topology, and AEC-Q101 availability-making it optimal for space-constrained, high-efficiency 48–120 VAC-derived power supplies where reliability and thermal performance are prioritized.

FAQ
What is the maximum junction temperature rating for the SF1603G?
The SF1603G has a maximum junction temperature (TJ MAX) of +150 °C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version I2104. This rating applies under continuous forward current conditions with proper heatsinking and must be derated linearly above case temperatures exceeding 100 °C, as shown in Figure 1 (Forward Current Derating Curve). Thermal design for SF1603G must ensure TJ remains below 150 °C during worst-case load and ambient conditions.
Does the SF1603G have AEC-Q101 qualification?
The base SF1603G is not AEC-Q101 qualified; however, the SF1603GH variant-identical in all electrical and thermal specifications-is explicitly qualified per AEC-Q101 Rev D. The "H" suffix denotes automotive-grade screening including HTOL, temperature cycling, and unbiased HAST. For automotive applications such as on-board chargers or DC/DC converters, SF1603GH must be specified; SF1603G is intended for industrial and commercial use only.
What is the reverse recovery time (trr) test condition for SF1603G?
The SF1603G reverse recovery time (trr) is specified as 35 ns maximum, measured under the standardized condition: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, with test circuit per Figure 6 in the Taiwan Semiconductor datasheet. This value reflects performance at room temperature and is representative of typical behavior in high-frequency switching applications like 200–500 kHz DC/DC converters where fast turn-off is critical to minimize switching loss.
How does the dual-die configuration of SF1603G affect PCB layout?
The SF1603G's dual-die configuration uses two separate anode leads (Leads 1 and 2) and a shared cathode tab, allowing flexible PCB routing for interleaved or redundant rectifier paths. Unlike single-die TO-220AC parts, this layout supports independent anode connections without external paralleling traces-reducing parasitic inductance and improving current sharing. Thermal vias should be placed under the full tab area, and mounting torque must not exceed 0.56 N·m to avoid die cracking.
What is the junction-to-case thermal resistance (RθJC) of SF1603G?
The SF1603G has a typical junction-to-case thermal resistance (RθJC) of 1.5 °C/W, as published in the Thermal Performance section of the Taiwan Semiconductor datasheet. This value is measured from the silicon junction to the metal tab surface under standardized mounting conditions and is essential for calculating junction temperature rise: TJ = TC + (PD × RθJC). Accurate heatsink selection for SF1603G requires using this RθJC value along with actual power dissipation and case temperature measurements.
