Product details
Overview
SF2006PTH from Taiwan Semiconductor is a 20A, 400V repetitive peak reverse voltage dual-die superfast rectifier in TO-247AD package, featuring 1.300 V forward voltage at 10 A and 25°C, 35 ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a center-tapped dual rectifier in high-efficiency DC-DC converters and snubber circuits.
For engineers reviewing the SF2006PTH datasheet, SF2006PTH pinout, SF2006PTH application, or SF2006PTH equivalent, key selection criteria include its 400 V VRRM, dual-die configuration with positive center-tap topology, AEC-Q101 qualification status, thermal resistance of 2.5 °C/W, and compatibility with high-frequency switching topologies requiring fast recovery and low conduction loss.
Technical Context
The SF2006PTH integrates two identical silicon die in a single TO-247AD package with shared cathode connection and isolated anodes-enabling center-tapped full-wave rectification without external wiring. Its glass-passivated junctions and optimized doping profile deliver 35 ns trr and <10 µA IR at 25°C.
This device operates across –55°C to +150°C junction temperature range with 2.5 °C/W RθJC, supporting forced-air or heatsink-mounted deployment in space-constrained industrial and automotive power stages where thermal management and surge robustness (180 A IFSM) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum non-repetitive reverse blocking voltage per diode; defines usable input voltage range in bridge or center-tap rectifiers |
| IF | 20 A - Continuous average forward current per diode; supports high-power output stages without derating below 100°C case temperature |
| VF @ 10 A, 25°C | 1.300 V - Forward voltage drop per diode; determines conduction loss (13 W total at 10 A) in high-current paths |
| trr | 35 ns - Reverse recovery time; enables operation up to ~3 MHz switching frequency before significant switching loss dominates |
| RθJC | 2.5 °C/W - Junction-to-case thermal resistance; allows direct heatsink mounting with predictable temperature rise under 20 A load |
| IFSM | 180 A - Non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients in SMPS and motor drives |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronics including temperature cycling, HTRB, and ESD; suitable for under-hood applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar superfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2004TV1 | 400 V VRRM, 20 A IF, 35 ns trr, but single-die TO-247; no center-tap configuration | Requires external dual-diode layout for center-tap function; higher board area and parasitic inductance | Select when discrete placement or separate anode routing is preferred over integrated dual-die topology |
| ON Semi MUR2040CTG | 400 V VRRM, 20 A IF, 60 ns trr, TO-247 package, AEC-Q101 qualified | Slower recovery increases switching loss in >200 kHz designs; same center-tap pinout but higher VF (1.55 V) | Choose when cost sensitivity outweighs efficiency targets, or where 60 ns trr meets system timing margin |
Compared with STTH2004TV1 and MUR2040CTG, the SF2006PTH uniquely combines AEC-Q101 qualification, 35 ns recovery, and monolithic center-tap architecture-enabling compact, thermally efficient, and automotive-compliant rectification without layout trade-offs.

FAQ
What is the maximum junction temperature rating for SF2006PTH?
The SF2006PTH has a maximum junction temperature (TJ) rating of +150°C and a minimum of –55°C. This wide operating range supports deployment in under-hood automotive environments and industrial enclosures without active cooling. The device maintains specified electrical performance across this full range, with thermal resistance of 2.5 °C/W enabling predictable heatsink sizing. Always verify case temperature in final layout using measured or simulated thermal data for SF2006PTH.
Is SF2006PTH pin-compatible with other parts in the SF200xPT family?
Yes, all SF200xPT and SF200xPTH devices-including SF2006PTH-share identical TO-247AD package dimensions, pinout (A1, A2, K), and mechanical mounting features. Voltage ratings differ across the family (50 V to 600 V), but physical layout, solder pad pattern, and thermal interface requirements remain consistent. This allows scalable BOM management while maintaining PCB reuse across designs targeting different input voltage ranges using SF2006PTH or related variants.
Does SF2006PTH require derating at elevated ambient temperatures?
Yes, SF2006PTH requires current derating above 100°C case temperature, per its forward current derating curve. At 125°C case temperature, the maximum continuous IF drops to approximately 12 A; at 150°C, it falls to zero. Derating ensures junction temperature stays within the –55°C to +150°C limit. Thermal design must account for RθJC = 2.5 °C/W and system-level RθCA to calculate actual TJ under load for SF2006PTH.
What does the "H" suffix in SF2006PTH signify?
The "H" suffix in SF2006PTH indicates full AEC-Q101 qualification-verified through temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD) testing per automotive standards. This distinguishes SF2006PTH from the non-H variant SF2006PT, which lacks formal automotive qualification. For automotive applications such as body control modules or lighting drivers, SF2006PTH is the required version to meet OEM component approval requirements.
How does the dual-die structure of SF2006PTH impact PCB layout compared to discrete diodes?
The monolithic dual-die structure of SF2006PTH integrates both anodes and a common cathode in one TO-247AD package, eliminating separate trace routing, vias, and thermal pads needed for two discrete diodes. This reduces PCB area by ~40%, lowers parasitic inductance in high-di/dt paths, and improves thermal coupling between dies. Layout simplicity and improved EMI performance make SF2006PTH especially advantageous in space-constrained, high-frequency power supplies where discrete alternatives would compromise SF2006PTH's system-level benefits.
