Product details
Overview
SFF1607G from Taiwan Semiconductor is a 500 V, 16 A super fast recovery rectifier diode in ITO-220AB package, featuring 1.700 V typical forward voltage at 8 A and 25 °C, 35 ns reverse recovery time, and dual-die construction for high-reliability DC/DC converter freewheeling paths.
For engineers reviewing the SFF1607G datasheet, SFF1607G pinout, SFF1607G application, or SFF1607G equivalent, key selection criteria include its 500 V repetitive peak reverse voltage, 125 A surge capability, junction-to-case thermal resistance of 1.5 °C/W, AEC-Q101 qualification option (SFF1607GH), and UL recognition (E-326243).
Technical Context
The SFF1607G implements a super fast recovery silicon PN junction with optimized carrier lifetime control to achieve 35 ns trr while maintaining low leakage (<10 µA at 25 °C) and stable VF across temperature. Its dual-die configuration enables symmetrical current sharing in bridge configurations without external balancing.
Designed for high-frequency switching topologies, it supports operation up to 100 kHz with minimal switching loss due to low junction capacitance (50 pF at 4 V) and tight thermal coupling to heatsink via ITO-220AB's metal tab. The device operates over -55 °C to +150 °C junction range and meets JESD201 Class 2 whisker resistance.

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 | 500 V VRRM, 16 A IF, 35 ns trr, TO-220AC package, VF = 1.75 V @ 8 A | Same voltage/current class but higher VF increases conduction loss by ~30 mW per diode at 8 A | Preferred where STMicroelectronics supply chain alignment is required; requires thermal validation due to TO-220AC's higher RθJC (2.0 °C/W) |
| IXYS MUR1650CT | 500 V VRRM, 16 A IF, 35 ns trr, TO-220AB package, VF = 1.65 V @ 8 A, dual common-cathode | Lower VF improves efficiency but common-cathode configuration limits flexibility in freewheeling vs. bridge use | Best for fixed dual-diode bridge designs; verify pin compatibility-cathode pins differ from SFF1607G's anode-tab/cathode-lead layout |
Compared with STTH1605D and IXYS MUR1650CT, the SFF1607G offers superior thermal performance (1.5 °C/W vs. ≥2.0 °C/W), UL recognition, and AEC-Q101-qualified variant availability-making it optimal for space-constrained, safety-critical, or automotive-grade power supplies requiring long-term reliability.

FAQ
What is the maximum junction temperature rating for the SFF1607G?
The SFF1607G has a maximum junction temperature (TJ MAX) of +150 °C, verified per absolute maximum ratings table. This allows operation in high-ambient environments when mounted on a heatsink capable of maintaining case temperature ≤95 °C at 16 A continuous forward current. Derating curves in the datasheet confirm usable current down to 0 A at 150 °C case temperature.
Is the SFF1607G pin-compatible with other devices in the SFF1601G–SFF1608G family?
Yes, all SFF1601G–SFF1608G devices share identical ITO-220AB packaging, pinout, and mechanical dimensions-including anode-tab and cathode-lead configuration. Voltage rating differences (50–600 V) do not affect physical or electrical interconnection; only electrical performance parameters vary across the family.
Does the SFF1607G meet automotive qualification standards?
The base SFF1607G is not AEC-Q101 qualified, but the SFF1607GH variant-identical in all electrical and thermal specifications-is explicitly qualified per AEC-Q101. The "H" suffix denotes qualification, and both versions share the same ITO-220AB package, marking code, and UL recognition file E-326243.
What is the reverse recovery time (trr) measurement condition for the SFF1607G?
The SFF1607G reverse recovery time is specified as 35 ns maximum under conditions of IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, measured per JEDEC standard test circuit. This value is confirmed across the full operating temperature range and applies to both individual dies in the dual-die configuration.
How does the SFF1607G's forward voltage compare to lower-voltage variants in the same family?
The SFF1607G exhibits a typical VF of 1.700 V at 8 A and 25 °C-higher than SFF1601G–SFF1604G (0.975 V) and SFF1605G–SFF1606G (1.300 V) due to increased doping gradient and wider depletion region required for 500 V blocking capability. This trade-off ensures reliable high-voltage operation without compromising trr or leakage.
