Product details
Overview
SF1608PT from Taiwan Semiconductor is a 16A, 600V super fast recovery dual rectifier in TO-247AD (TO-3P) package with center-tapped configuration, 1.70V forward voltage at 8A/25°C, 35ns reverse recovery time, and AEC-Q101 qualification available. It serves as a high-efficiency freewheeling and snubber diode in high-frequency DC-DC converters.
For engineers reviewing the SF1608PT datasheet, SF1608PT pinout, SF1608PT application, or SF1608PT equivalent, key selection criteria include peak reverse voltage rating (600V), thermal resistance (2°C/W), dual-die center-tap topology, low VF at high current, and automotive-grade reliability options.
Technical Context
The SF1608PT integrates two identical silicon die in a single TO-247AD package with shared cathode and isolated anodes - forming a positive center-tap dual rectifier. Its superfast recovery (trr ≤ 35ns) enables operation in switching frequencies up to several hundred kHz.
Designed with glass-passivated junctions and optimized doping profiles, it achieves low thermal resistance (RθJC = 2°C/W) and stable reverse leakage (< 500µA at 125°C), supporting high-power density designs in constrained thermal environments.

Applications
| DC-DC Converter | Snubber Circuit |
|---|---|
Use Scenario: High-efficiency isolated buck-boost converter in telecom power shelf with 380–400V DC input. IC Role / Device Role / Timing Role: Dual rectifier provides synchronous full-wave output rectification with shared cathode return path. Use Value: 35ns trr and 1.70V VF reduce switching and conduction losses, improving system efficiency by ≥1.2% at 12A load. | Use Scenario: RCD snubber network across MOSFET drain-source in flyback converter operating at 250kHz. IC Role / Device Role / Timing Role: Fast-recovery clamp diode absorbs turn-off energy and limits voltage overshoot during switching transitions. Use Value: Low Qrr and 600V VRRM prevent snap-off and secondary breakdown while maintaining <15ns delay in clamping response. |
| Freewheeling Diode | Lighting Driver |
Use Scenario: High-current LED driver with buck controller driving 12–24V strings at 10–15A. IC Role / Device Role / Timing Role: Freewheeling path for inductor current during low-side switch off-time in continuous conduction mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual superfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1606D | 600V VRRM, 16A IF, trr = 35ns, but TO-247AC package (non-isolated tab); RθJC = 2.5°C/W | Requires insulating washer for heatsink mounting; higher thermal resistance increases junction temp by ~5°C at 16A | Preferred where cost sensitivity outweighs thermal margin; verify isolation compliance for safety-critical designs |
| IXYS MBR1660CT | 600V VRRM, 16A IF, Schottky construction - zero reverse recovery but limited to 175°C max junction temp and higher VF (2.1V typ) | Not suitable for high-temperature or high-VR snubber use due to leakage rise above 125°C | Select only for low-noise, ultra-low-loss applications below 100°C ambient; avoid in automotive under-hood locations |
Compared with STTH1606D and MBR1660CT, the SF1608PT offers superior thermal performance (2°C/W), certified isolation-ready packaging, and AEC-Q101 availability - making it optimal for space-constrained, high-reliability industrial and automotive power stages where thermal headroom and safety certification are critical.

FAQ
What is the maximum junction temperature rating for the SF1608PT?
The SF1608PT has a maximum junction temperature (TJ) of +150°C, with operational range from –55°C to +150°C. This rating is validated across all electrical parameters in the datasheet and supports sustained 16A conduction when case temperature remains ≤100°C, leveraging its 2°C/W junction-to-case thermal resistance. The SF1608PT maintains specified VF and IR performance within this full range.
Does the SF1608PT have AEC-Q101 qualification?
Yes, the SF1608PT is available in an AEC-Q101 qualified version denoted by the suffix "H" (i.e., SF1608PTH). This variant undergoes full stress testing per AEC-Q101 Rev D, including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing - confirming suitability for automotive powertrain and body electronics applications.
What is the pin configuration of the SF1608PT in TO-247AD package?
The SF1608PT uses a 3-pin TO-247AD (TO-3P) package with Anode1 (lead 1), Cathode (metal tab), and Anode2 (lead 2) terminals. The cathode is internally common to both dies and electrically tied to the isolated metal tab - requiring proper insulation when mounted to a heatsink. Polarity is marked on the device body per the provided marking diagram.
How does the SF1608PT's reverse recovery time compare to standard FRDs?
The SF1608PT achieves trr ≤ 35ns under IF = 0.5A, IR = 1.0A, Irr = 0.25A conditions - approximately 40–60% faster than legacy fast recovery diodes (e.g., 1N5408: ~2000ns). This reduction directly lowers switching losses and EMI generation in high-frequency converters, enabling cleaner waveforms and relaxed filter design in 200–500kHz SMPS applications.
Is the SF1608PT halogen-free and RoHS compliant?
Yes, the SF1608PT complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all terminations use matte tin plating meeting J-STD-002 solderability standards - ensuring environmental compliance and long-term reliability in lead-free assembly processes.
