Product details
Overview
SF1607G from Taiwan Semiconductor is a 16A, 500V super fast recovery rectifier diode in TO-220AB package with dual-die configuration, VF = 1.700 V at IF = 8 A and TJ = 25°C, trr = 35 ns, and RθJC = 1.5 °C/W - used in high-frequency switching mode power supplies for freewheeling and output rectification.
For engineers reviewing the SF1607G datasheet, SF1607G pinout, SF1607G application, or SF1607G equivalent, key selection criteria include peak reverse voltage (500 V), surge current rating (125 A), thermal resistance (1.5 °C/W), junction temperature limit (+150 °C), and AEC-Q101 qualification status where specified.
Technical Context
The SF1607G is a single-phase, dual-die super fast rectifier optimized for high-efficiency DC/DC conversion and SMPS output stages. Its 35 ns reverse recovery time and low 1.700 V forward voltage at 8 A enable reduced switching losses in 50–500 kHz operating ranges.
Designed for surface-mount-compatible through-hole mounting with TO-220AB mechanical form factor, it supports forced-air or heatsink-cooled operation up to 150 °C junction temperature and meets JESD201 Class 2 whisker resistance and RoHS/halogen-free compliance per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 500 V - maximum repetitive reverse blocking voltage; defines safe operating range in 400 V DC bus applications |
| IF | 16 A - average forward current rating at TC = 100 °C; determines continuous conduction capability in power stage design |
| IFSM | 125 A - non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current handling without failure |
| VF | 1.700 V @ IF = 8 A, TJ = 25 °C - forward voltage drop directly impacts conduction loss and thermal design margin |
| trr | 35 ns - reverse recovery time; enables stable operation in high-frequency converters up to ~500 kHz |
| RθJC | 1.5 °C/W - junction-to-case thermal resistance; allows accurate heatsink sizing for target ΔT under 16 A load |
| CJ | 60 pF @ 1 MHz, VR = 4 V - junction capacitance affects high-frequency noise and snubber design requirements |
Pinout & Package
TO-220AB package with center-tab cathode configuration: Pin 1 (Anode 1), Pin 2 (Cathode common tab), Pin 3 (Anode 2). Matte tin-plated leads compliant with J-STD-002 solderability; polarity marked on device body.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1605D | 16 A, 500 V, VF = 1.75 V @ 8 A, trr = 30 ns, TO-220AC package (single anode) | Single-diode configuration requires two devices for dual-anode function; slightly faster trr but higher VF | Select when layout allows discrete placement and tighter trr tolerance is prioritized over integration |
| IXYS MUR1650CT | 16 A, 500 V, VF = 1.85 V @ 8 A, trr = 35 ns, TO-220AB dual common-cathode | Common-cathode instead of common-anode; pinout incompatible with SF1607G's dual-anode topology | Choose only if circuit redesign accommodates cathode-common routing and thermal interface adjustment |
Compared with STTH1605D and IXYS MUR1650CT, the SF1607G offers integrated dual-anode topology in TO-220AB with balanced VF/trr trade-off and verified AEC-Q101 qualification path - making it optimal for space-constrained, high-reliability dual-switching-node rectification.

FAQ
What is the maximum junction temperature rating for SF1607G?
The SF1607G has a maximum junction temperature (TJ MAX) of +150 °C, validated across its full operating range from –55 °C to +150 °C. This rating enables reliable operation in thermally demanding environments such as enclosed power supplies or automotive under-hood applications when paired with appropriate heatsinking per its 1.5 °C/W RθJC specification. Derating curves in the official datasheet define allowable current versus case temperature.
Does SF1607G support automotive-grade qualification?
Yes - the SF1607G has an AEC-Q101-qualified variant designated SF1607GH, which undergoes full stress testing per the AEC-Q101 standard including temperature cycling, mechanical shock, and humidity bias. The base SF1607G is not automatically qualified; only units ordered with the "H" suffix meet automotive reliability requirements. Always verify ordering code and packaging label before deployment in automotive systems.
What is the reverse recovery time (trr) of SF1607G and how is it measured?
The SF1607G has a typical reverse recovery time (trr) of 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A using the test circuit defined in Figure 6 of the datasheet. This value reflects performance at room temperature and remains stable across its rated junction temperature range, enabling predictable timing behavior in high-frequency switching topologies like LLC resonant converters.
How does the dual-die structure of SF1607G affect PCB layout and thermal design?
The SF1607G's dual-die TO-220AB package integrates two independent 16 A/500 V rectifiers sharing a common cathode tab (Pin 2), allowing compact dual-anode routing without inter-device mismatch. Thermally, the shared tab provides a single low-impedance path to heatsink - requiring only one mounting screw and uniform thermal interface material coverage. Layout must maintain clearance between Anode 1 (Pin 1) and Anode 2 (Pin 3) traces to prevent cross-conduction in high-dV/dt environments.
What is the forward voltage (VF) specification for SF1607G and at what conditions is it guaranteed?
The SF1607G specifies a maximum forward voltage (VF) of 1.700 V at IF = 8 A and TJ = 25 °C, measured under pulsed conditions (PW = 0.3 ms). At elevated temperatures (e.g., TJ = 125 °C), VF decreases slightly due to semiconductor physics - typical values range from 1.55–1.62 V. This parameter directly determines conduction loss (Pcond ≈ VF × IF) and must be included in thermal modeling for system-level efficiency calculation.
