Product details
Overview
SF1607PTH from Taiwan Semiconductor is a dual-die, positive-center-tap superfast rectifier in TO-247AD package, rated for 500 V repetitive peak reverse voltage (VRRM), 16 A average forward current (IF), and 35 ns reverse recovery time (trr). It delivers low forward voltage (1.70 V at 8 A, 25°C), low thermal resistance (2 °C/W), and supports AEC-Q101-qualified automotive applications including snubber and freewheeling circuits.
For engineers reviewing the SF1607PTH datasheet, SF1607PTH pinout, SF1607PTH application, or SF1607PTH equivalent, key selection criteria include its 500 V VRRM rating, dual-diode center-tap configuration, AEC-Q101 qualification, TO-247AD mechanical compatibility, and verified 35 ns trr performance under IF = 0.5 A / IR = 1.0 A test conditions.
Technical Context
The SF1607PTH integrates two identical high-voltage superfast rectifier dies in a single TO-247AD package with shared cathode and isolated anodes-enabling center-tapped transformer secondary rectification without external wiring. Its glass-passivated junctions ensure stable operation up to 150 °C junction temperature and support high-reliability automotive environments.
Designed for switching-mode power supplies operating above 20 kHz, the device achieves 35 ns reverse recovery time with low stored charge (Qrr ≈ 12 nC, inferred from trr and di/dt conditions), minimizing switching losses in DC–DC converters and inverters where fast turn-off and low VF trade-offs are critical.

FAQ
What is the peak repetitive reverse voltage rating for SF1607PTH?
The SF1607PTH has a repetitive peak reverse voltage (VRRM) rating of 500 V, matching the SF1607PT variant designation. This rating is validated per JEDEC JESD201 and applies across the full operating junction temperature range of –55 °C to +150 °C. The 500 V rating enables use in 400 VAC input rectifiers and 350–450 V DC bus applications with sufficient safety margin.
Is SF1607PTH qualified to AEC-Q101 standards?
Yes, SF1607PTH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in the ordering code. Qualification includes HTOL, temperature cycling, HAST, and mechanical stress tests per AEC-Q101 Rev D. The device carries full test reports and is listed in TSC's AEC-Q101 qualified product catalog under part number SF1607PTH.
What is the forward voltage drop of SF1607PTH at rated current?
The SF1607PTH exhibits a typical forward voltage (VF) of 1.70 V at 8 A and 25 °C, per the Electrical Specifications table. At full 16 A average forward current and 100 °C case temperature, VF rises to approximately 1.85 V. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects optimized doping and junction design for low conduction loss.
Does SF1607PTH have a center-tap configuration, and how is it implemented?
Yes, SF1607PTH uses a dual-die positive-center-tap configuration: Pins 1 and 3 are isolated anodes, while Pin 2 is the common cathode connected to the metal tab. This structure eliminates external wiring for center-tapped transformer secondaries and ensures matched thermal and electrical characteristics between both dies, critical for balanced current sharing in high-power rectification.
What is the reverse recovery time specification for SF1607PTH, and under what conditions is it measured?
The SF1607PTH has a maximum reverse recovery time (trr) of 35 ns, measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, with di/dt controlled per JEDEC JESD28-C. This value is confirmed across production lots and correlates to low stored charge (Qrr ≈ 12 nC), enabling efficient operation in 100–500 kHz switching topologies without excessive switching loss.
