Product details
Overview
SF1605PTH from Taiwan Semiconductor is a dual-die, positive-center-tap superfast rectifier in TO-247AD (TO-3P) package, rated for 16 A average forward current, 400 V repetitive peak reverse voltage (VRRM), and 35 ns reverse recovery time (trr). It delivers low forward voltage (1.30 V at 8 A, 25°C), low thermal resistance (2°C/W), and supports high-efficiency DC-DC converters and snubber circuits.
For engineers reviewing the SF1605PTH datasheet, SF1605PTH pinout, SF1605PTH application, or SF1605PTH equivalent, key selection considerations include its AEC-Q101 qualification, dual-die center-tap configuration, 400 V VRRM, 150 A non-repetitive surge rating, and thermal performance under industrial switching-mode loads.
Technical Context
The SF1605PTH integrates two identical silicon rectifier dies in a single TO-247AD package with shared cathode and isolated anodes - forming a positive-center-tap topology ideal for full-wave rectification without external center-tapped transformers. Its superfast recovery (trr ≤ 35 ns) enables operation in high-frequency switching topologies up to several hundred kHz.
Designed for automotive-grade reliability, the device features glass-passivated junctions, matte tin-plated leads compliant with J-STD-002, and meets JESD201 Class 2 whisker resistance. Junction temperature range spans −55°C to +150°C, supporting operation in demanding under-hood or industrial power environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking voltage per diode; defines usable input voltage headroom in bridge or center-tap rectifier designs |
| IF | 16 A - continuous average forward current at case temperature ≤ 100°C; determines steady-state power handling capability |
| IFSM | 150 A - non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current tolerance in SMPS inputs |
| trr | 35 ns - reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables efficient operation above 200 kHz switching frequencies |
| VF | 1.30 V - forward voltage per diode at IF = 8 A, TJ = 25°C; directly impacts conduction loss and thermal design in high-current paths |
| RθJC | 2°C/W - junction-to-case thermal resistance; allows accurate heatsink sizing for 16 A continuous operation with <100°C case rise |
| IR | 10 µA max @ 25°C - reverse leakage per diode at rated VR; critical for low-power standby and high-impedance bias networks |
Pinout & Package
Package: TO-247AD (TO-3P), 3-terminal molded plastic case with isolated anodes and common cathode. Mounting torque ≤ 1.13 N·m; matte tin-plated leads; UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Input terminal for first rectifier die | Connected to AC input leg 1 in center-tap rectifier; must be routed with low-inductance path for fast recovery |
| Anode 2 (A2) | Input terminal for second rectifier die | Connected to AC input leg 2 in center-tap rectifier; electrically isolated from A1 but thermally coupled in shared package |
| Cathode (K) | Common output node (positive center-tap) | Provides DC+ output; serves as reference for both dies; carries full 16 A load current and requires robust PCB copper pour |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power electronics including engine control modules and onboard chargers requiring extended temperature and reliability compliance |
| Positive center-tap dual-die construction | Enables transformerless full-wave rectification with single-output DC polarity; eliminates need for dual secondary windings or external center tap |
| Glass passivated junctions | Ensures long-term stability of reverse characteristics and leakage current under humidity, thermal cycling, and high-voltage stress |
| Low RθJC = 2°C/W | Reduces thermal bottleneck between die and heatsink, allowing higher sustained current density without derating in compact layouts |
| UL Recognized (E-326243) | Confirms flammability, electrical insulation, and construction safety for use in end-equipment requiring regulatory certification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar superfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1604D | Single-die TO-247, 400 V VRRM, 35 ns trr, but no center-tap configuration; requires external dual-diode layout | Not suitable for center-tap transformerless designs; needs PCB area for two separate devices and interconnects | Select when board space allows discrete implementation and thermal isolation between dies is preferred |
| IXYS MUR1640CT | Dual-die TO-247 with center-tap, 400 V VRRM, 60 ns trr, 1.25 V VF - slower recovery but slightly lower conduction loss | Better for <100 kHz applications where recovery loss is secondary to forward drop; not AEC-Q101 qualified | Select for cost-sensitive industrial supplies where automotive qualification is unnecessary and 60 ns trr suffices |
Compared with STTH1604D and IXYS MUR1640CT, the SF1605PTH uniquely combines AEC-Q101 qualification, 35 ns recovery, and integrated center-tap topology-enabling compact, automotive-grade rectification without layout compromise or thermal splitting.

FAQ
What is the peak repetitive reverse voltage rating for SF1605PTH?
The SF1605PTH has a repetitive peak reverse voltage (VRRM) rating of 400 V per diode. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version G2103), where SF1605PT/SF1605PTH is explicitly assigned VRRM = 400 V. It defines the maximum allowable reverse-biased voltage the device can block repeatedly without breakdown under normal operating conditions.
Is SF1605PTH AEC-Q101 qualified, and what does the "H" suffix indicate?
Yes, SF1605PTH is AEC-Q101 qualified. The "H" suffix in the ordering code (SF1605PTH vs. SF1605PT) explicitly denotes AEC-Q101 qualification per Taiwan Semiconductor's Ordering Information table. This certification covers stress testing for temperature cycling, humidity, mechanical shock, and other automotive-grade reliability requirements - making SF1605PTH suitable for under-hood and safety-critical power applications.
What is the forward voltage drop of SF1605PTH at rated current?
The forward voltage (VF) of SF1605PTH is 1.30 V maximum per diode at IF = 8 A and TJ = 25°C, as specified in the Electrical Specifications table. This value reflects conduction loss under typical operating conditions and is consistent across the SF1605PT/SF1605PTH variant group. At higher junction temperatures or currents, VF increases predictably per the device's forward characteristic curve.
Does SF1605PTH have a center-tap configuration, and how is it implemented?
Yes, SF1605PTH uses a positive-center-tap configuration implemented via dual isolated silicon dies in a single TO-247AD package. Anode 1 and Anode 2 are electrically separate input terminals, while the Cathode (K) serves as the common output node - effectively forming a center-tapped rectifier without requiring an external center-tapped transformer. This is confirmed in the FEATURES section and Mechanical Data description.
What is the thermal resistance from junction to case for SF1605PTH?
The junction-to-case thermal resistance (RθJC) of SF1605PTH is 2°C/W, as published in the Thermal Performance section of the datasheet. This value applies to both dies and is measured under standard mounting conditions with proper heatsink interface. It enables precise thermal modeling for heatsink selection when operating at 16 A average forward current and ambient temperatures up to 100°C.
