Product details
Overview
SF1603PT from Taiwan Semiconductor is a 16A, 150V super fast recovery dual rectifier in TO-247AD package, featuring 35ns reverse recovery time, 0.95V forward voltage at 8A/25°C, and 2°C/W junction-to-case thermal resistance. It serves as a center-tapped dual diode for high-efficiency DC-DC converters and snubber circuits in industrial power supplies.
For engineers reviewing the SF1603PT datasheet, SF1603PT pinout, SF1603PT application, or SF1603PT equivalent, key selection criteria include its 150V VRRM, dual-die configuration with positive center-tap, glass passivated junctions, AEC-Q101 qualification option (SF1603PTH), and UL recognition (E-326243).
Technical Context
The SF1603PT integrates two identical silicon die in a single TO-247AD (TO-3P) package with shared cathode connection and isolated anodes - forming a positive center-tap dual rectifier topology. Its superfast recovery (trr = 35ns) enables operation in high-frequency switching topologies up to several hundred kHz.
Thermal performance is defined by RθJC = 2°C/W and TJMAX = 150°C, supporting continuous 16A conduction with proper heatsinking. The device uses glass passivation for robust junction protection and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage per diode; defines safe blocking capability in 150V-rated power stages |
| IF | 16 A - Continuous forward current rating; supports high-power rectification without derating below 75°C case temperature |
| trr | 35 ns - Reverse recovery time at IF=0.5A, IR=1.0A, Irr=0.25A; enables low-loss operation in 200–500 kHz SMPS |
| VF | 0.95 V - Forward voltage per diode at IF=8A and TJ=25°C; contributes to <1.5W conduction loss at full rated current |
| RθJC | 2 °C/W - Junction-to-case thermal resistance; allows direct mounting to heatsink for efficient thermal management |
| IFSM | 150 A - Non-repetitive surge current (8.3ms half-sine); withstands startup inrush and transient overloads |
| CJ | 85 pF - Junction capacitance per diode at 1MHz/4V; impacts high-frequency switching noise and EMI filter design |

Applications
| DC-DC Converter | Snubber Circuit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar superfast dual rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602CT | VRRM = 200V, trr = 35ns, VF = 1.05V @ 8A, TO-220AC package | Higher voltage rating but lower thermal performance (RθJC ≈ 3.5°C/W); unsuitable for 16A continuous without oversized heatsink | Select when 200V blocking is required and board space allows TO-220 footprint; verify thermal margin at full load |
| IXYS MUR1620CT | VRRM = 200V, trr = 35ns, VF = 1.1V @ 8A, TO-220AC package | Same speed but higher forward drop and inferior thermal resistance; not AEC-Q101 qualified | Prefer for cost-sensitive industrial designs where 150V rating suffices and AEC-Q101 is unnecessary |
Compared with STTH1602CT and IXYS MUR1620CT, the SF1603PT offers superior thermal management (2°C/W vs. ≥3.5°C/W), lower forward voltage (0.95V vs. ≥1.05V), and optional AEC-Q101 qualification - making it optimal for space-constrained, high-efficiency, or automotive-qualified 150V dual-rectifier applications.

FAQ
What is the maximum junction temperature rating for the SF1603PT?
The SF1603PT has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating applies across the full operating range and supports reliable operation in high-ambient environments when mounted with appropriate thermal interface material and heatsink. The SF1603PT maintains specified electrical parameters up to this limit, provided case temperature remains within derated limits per the forward current derating curve.
Does the SF1603PT have AEC-Q101 qualification?
The SF1603PT itself is not AEC-Q101 qualified, but the pin-compatible variant SF1603PTH is explicitly qualified per AEC-Q101 Rev D. Both share identical electrical and thermal specifications, with the "H" suffix indicating automotive-grade screening and test compliance. For automotive applications requiring qualification evidence, SF1603PTH must be selected and sourced accordingly.
What is the reverse recovery time (trr) of the SF1603PT and under what test conditions?
The SF1603PT has a reverse recovery time (trr) of 35 ns, measured under the conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, and TJ = 25°C. This value is confirmed in the Electrical Specifications table of the official datasheet and reflects typical performance for both diodes in the dual configuration.
How is the center-tap configured in the SF1603PT TO-247AD package?
The SF1603PT implements a positive center-tap configuration via internal connection of the two cathodes to the common K terminal, while Anode 1 and Anode 2 remain electrically isolated. This allows the device to function as two independent high-speed diodes sharing a common output - ideal for center-tapped transformer secondary rectification or dual-phase freewheeling paths.
What is the junction-to-case thermal resistance (RθJC) of the SF1603PT?
The SF1603PT has a typical junction-to-case thermal resistance (RθJC) of 2°C/W, as specified in the Thermal Performance section of the datasheet. This value is measured from the silicon die junction to the metal tab of the TO-247AD package and enables accurate thermal modeling when designing heatsink interfaces for continuous 16A operation.
