Product details
Overview
SF1603PTH from Taiwan Semiconductor is a dual-die, positive-center-tap superfast rectifier in TO-247AD package, rated for 150 V repetitive peak reverse voltage (VRRM), 16 A average forward current (IF), and 35 ns reverse recovery time (trr). It delivers low forward voltage (0.95 V at 8 A, 25°C), low thermal resistance (2 °C/W), and is AEC-Q101 qualified for automotive-grade reliability.
For engineers reviewing the SF1603PTH datasheet, SF1603PTH pinout, SF1603PTH application, or SF1603PTH equivalent, key selection considerations include its center-tapped dual-diode configuration, 150 V VRRM rating, AEC-Q101 qualification, TO-247AD mechanical compatibility, and suitability for high-efficiency DC/DC and switching-mode power supplies requiring fast recovery and low conduction loss.
Technical Context
The SF1603PTH integrates two identical silicon rectifier dies in a single TO-247AD package with shared cathode and isolated anodes - enabling center-tap topology without external wiring. Its superfast recovery (trr ≤ 35 ns) and low VF support high-frequency switching up to several hundred kHz.
Designed for automotive and industrial power conversion, it features glass-passivated junctions, UL 94V-0 molding compound, matte tin-plated leads compliant with J-STD-002, and JESD201 Class 2 whisker resistance - all validated under AEC-Q101 stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum non-repetitive reverse voltage per diode; defines safe blocking capability in flyback or snubber circuits |
| IF | 16 A - continuous average forward current at case temperature ≤ 100°C; supports high-power DC/DC output stages |
| trr | 35 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables efficient operation in 100–500 kHz SMPS designs |
| VF | 0.95 V - forward voltage per diode at IF = 8 A, TJ = 25°C; reduces conduction loss and improves system efficiency |
| RθJC | 2 °C/W - junction-to-case thermal resistance; allows direct heatsink mounting with predictable thermal rise |
| IFSM | 150 A - non-repetitive surge current (8.3 ms half-sine); withstands inrush and transient overloads |
| TJ max | 150 °C - maximum junction temperature; supports operation in under-hood automotive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar superfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602CW | 100 V VRRM, same IF (16 A), TO-247 package, but single-diode + external center-tap wiring required | Lacks integrated dual-die center-tap; requires additional PCB traces and layout area | Choose when lower VRRM suffices and board space permits discrete implementation |
| IXYS MUR1620CT | 200 V VRRM, 16 A IF, TO-220AB package, no AEC-Q101 qualification | Higher voltage rating but smaller package limits thermal performance (RθJC ≈ 3.5 °C/W) | Prefer for cost-sensitive industrial applications where AEC-Q101 is not mandated |
Compared with STTH1602CW and IXYS MUR1620CT, the SF1603PTH uniquely combines 150 V VRRM, integrated center-tap topology, AEC-Q101 qualification, and superior thermal resistance (2 °C/W) - making it optimal for space-constrained, thermally demanding automotive DC/DC and lighting systems.

FAQ
What is the peak repetitive reverse voltage rating of the SF1603PTH?
The SF1603PTH has a repetitive peak reverse voltage (VRRM) rating of 150 V per diode. This value is fixed for the SF1603PTH variant within the SF1601PT–SF1608PT family and is verified per the G2103 datasheet. It defines the maximum reverse-biased voltage the device can block continuously without breakdown under specified thermal conditions.
Is the SF1603PTH pin-compatible with other parts in the SF160xPT series?
Yes - all SF160xPT and SF160xPTH variants share identical TO-247AD (TO-3P) package dimensions, pinout (A1/A2/K), and mechanical mounting interface. The SF1603PTH differs only in VRRM (150 V) and forward voltage characteristics; electrical substitution requires verification of voltage and thermal margins for the target application.
Does the SF1603PTH require a heatsink in typical operation?
Yes - while the SF1603PTH has low thermal resistance (RθJC = 2 °C/W), sustained 16 A operation generates significant power loss. For reliable long-term performance above ~5 A average current, a properly sized heatsink mounted to the case via the TO-247AD mounting hole is required to maintain junction temperature below 150 °C.
What does the "H" suffix in SF1603PTH signify?
The "H" suffix in SF1603PTH indicates full AEC-Q101 qualification per Rev. G2103. This includes stress testing for temperature cycling, high-temperature operating life, unbiased highly accelerated stress test (uHAST), and mechanical shock - confirming suitability for automotive power electronics where reliability and failure mode robustness are critical.
Can the SF1603PTH be used in freewheeling applications with 400 V bus voltage?
No - the SF1603PTH is rated for 150 V VRRM and must not be used in circuits where reverse voltage exceeds this rating. For 400 V bus applications, select SF1606PTH (400 V VRRM) or SF1607PTH (500 V VRRM) from the same family, which share identical package, pinout, and thermal performance but higher blocking voltage.
