Product details
Overview
SF1602PT from Taiwan Semiconductor is a 16A, 100V superfast dual-center-tap rectifier in TO-247AD package, featuring 35ns reverse recovery time, 0.95V forward voltage at 8A/25°C, and AEC-Q101 qualification option. It serves as a high-efficiency freewheeling and snubber diode in automotive DC-DC converters and industrial switching inverters.
For engineers reviewing the SF1602PT datasheet, SF1602PT pinout, SF1602PT application, or SF1602PT equivalent, key selection criteria include its 100V VRRM, dual-die center-tap configuration, low RθJC of 2°C/W, and verified performance under 150A surge current and 150°C junction temperature limits.
Technical Context
The SF1602PT integrates two identical superfast rectifier dies in a single TO-247AD package with shared cathode (center-tap) configuration, enabling balanced dual-path conduction. Its glass-passivated junctions and optimized epitaxial structure deliver consistent 35ns trr and <10µA IR at 25°C across production lots.
This device operates within -55°C to +150°C junction range and sustains 150A non-repetitive surge current under 8.3ms half-sine waveform. Thermal resistance of 2°C/W allows direct heatsink mounting without thermal interface material in medium-power applications up to 16A continuous.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe operating ceiling in 100V bus systems |
| IF | 16 A - Continuous forward current rating at case temperature ≤75°C; supports sustained 16A conduction without derating |
| trr | 35 ns - Measured reverse recovery time at IF=0.5A, IR=1.0A, Irr=0.25A; enables >1MHz switching in SMPS |
| VF | 0.95 V - Forward voltage per diode at 8A and 25°C; contributes to <1.5W conduction loss per die at rated current |
| RθJC | 2 °C/W - Junction-to-case thermal resistance; permits 130°C temperature rise at 16A with 260°C max junction limit |
| IFSM | 150 A - Peak non-repetitive surge current for 8.3ms half-sine; withstands inrush and fault transients in motor drives |
Pinout & Package
Package: TO-247AD (TO-3P), 3-terminal molded plastic case with matte tin-plated leads, UL 94V-0 rated compound, and polarity marked on top surface.

Equivalent & Alternatives
The following parts are listed as comparable options for similar superfast dual-center-tap rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602D | VRRM = 100V, trr = 30ns, VF = 0.92V @ 8A, TO-247 package, single-die dual-anode | No center-tap cathode; requires external parallel connection for center-tap topology | Select when board layout allows discrete dual-diode placement and tighter trr is prioritized over integration |
| IXYS MUR1620CT | VRRM = 200V, trr = 35ns, VF = 1.15V @ 8A, TO-220AB package, center-tap | Higher VRRM but lower surge rating (125A) and higher thermal resistance (3.5°C/W) | Choose for 200V systems where space constraints favor TO-220 and 100V margin is acceptable |
Compared with STTH1602D and IXYS MUR1620CT, the SF1602PT uniquely combines true integrated center-tap topology, 2°C/W thermal resistance, and AEC-Q101 qualification option-making it optimal for space-constrained, thermally demanding automotive and industrial rectification where layout simplicity and reliability are critical.

FAQ
What is the maximum junction temperature rating for SF1602PT?
The SF1602PT has a maximum junction temperature (TJ) of +150°C, validated across its full operating range from -55°C to +150°C. This rating is maintained under continuous 16A forward current with case temperature held at or below 75°C, supported by its 2°C/W junction-to-case thermal resistance. Derating is required above 75°C case temperature per the forward current derating curve in the official TSC datasheet.
Does SF1602PT have AEC-Q101 qualification?
The SF1602PT is available in an AEC-Q101 qualified version denoted by the suffix "H" (i.e., SF1602PTH). The base SF1602PT part is not automatically qualified; only units ordered with the "H" suffix undergo full AEC-Q101 stress testing including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. Always verify ordering code suffix when specifying for automotive applications.
What is the reverse recovery time (trr) test condition for SF1602PT?
The SF1602PT reverse recovery time of 35 ns is measured under standardized conditions: forward current IF = 0.5 A, reverse current IR = 1.0 A, reverse recovery current Irr = 0.25 A, and junction temperature TJ = 25°C. These conditions align with JEDEC JESD24-11 and are documented in the "Electrical Specifications" section of the TSC SF1601PT–SF1608PT datasheet Version G2103.
How does the center-tap configuration of SF1602PT affect PCB layout?
The SF1602PT's integrated center-tap cathode eliminates the need for external wire bonding or parallel diode placement to achieve center-tapped rectification. This reduces PCB trace inductance, improves current sharing symmetry between anodes, and cuts assembly steps-particularly valuable in high-density automotive power modules where layout parasitics directly impact EMI and efficiency.
What is the marking code for SF1602PT on the device body?
The SF1602PT is laser-marked with "SF1602PT" followed by green compound indicator "G", date code (e.g., "2422" for week 22 of 2024), and factory code "F". This marking appears on the top surface of the TO-247AD package and matches the ordering code exactly-ensuring unambiguous identification during incoming inspection and traceability audits.
