Product details
Overview
SF2005PTH from Taiwan Semiconductor is a 20A, 400V repetitive peak reverse voltage (VRRM) superfast rectifier in TO-247AD package, featuring dual-die positive-center-tap configuration, 35ns reverse recovery time (trr), and 1.300V forward voltage at 10A/25°C. It serves as a high-efficiency freewheeling or snubber diode in automotive-grade DC-DC converters.
For engineers reviewing the SF2005PTH datasheet, SF2005PTH pinout, SF2005PTH application, or SF2005PTH equivalent, key selection criteria include its AEC-Q101 qualification, 400V VRRM, 180A IFSM, dual-diode thermal coupling in TO-247AD, and verified 2.5°C/W junction-to-case thermal resistance.
Technical Context
This device integrates two monolithic 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 superfast recovery (trr = 35ns) minimizes switching losses in high-frequency SMPS topologies above 100kHz.
The glass-passivated junctions ensure stable leakage performance up to 125°C (IR ≤ 400µA), while low RθJC = 2.5°C/W supports sustained 20A conduction under forced-air cooling. The AEC-Q101 qualification confirms robustness for automotive powertrain and body electronics environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum non-repetitive reverse blocking voltage per diode; defines usable input range in 28V–48V automotive DC-DC stages. |
| IF | 20 A - Continuous average forward current at TC = 100°C; enables compact heatsink design in space-constrained inverters. |
| trr | 35 ns - Measured at IF = 0.5A, IR = 1.0A, Irr = 0.25A; ensures minimal tail current loss in 200kHz+ synchronous rectifier control schemes. |
| VF | 1.300 V @ 10A/25°C - Forward drop per diode; contributes to <1.5W conduction loss at rated load, improving system efficiency over Schottky alternatives. |
| RθJC | 2.5 °C/W - Junction-to-case thermal resistance; allows direct mounting to cold plates without thermal interface material degradation concerns. |
| IFSM | 180 A - Non-repetitive surge rating (8.3ms half-sine); withstands inrush currents during cold-start in 12V/24V battery-fed systems. |
Pinout & Package
Package: TO-247AD (TO-3P), 3-terminal molded case with matte tin-plated leads, UL 94V-0 rated compound, and polarity marked on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | First diode anode | Connects to primary-side switch node in center-tapped forward converter; electrically isolated from A2. |
| Anode 2 (A2) | Second diode anode | Connects to secondary winding midpoint in push-pull topology; shares cathode with A1 diode. |
| Cathode (K) | Common cathode | Output node for full-wave rectified DC; carries full 20A load current; thermally coupled to both dies. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power modules requiring zero defect rate across temperature cycling, humidity, and mechanical shock. |
| Dual-die positive center-tap | Enables transformerless full-wave rectification with single-package layout; eliminates interconnect inductance between discrete diodes. |
| Glass passivated junctions | Ensures long-term IR stability under humid conditions and prevents parametric drift after 1000hr HTOL testing at 150°C. |
| Superfast trr = 35ns | Reduces reverse recovery charge Qrr to <15nC, lowering EMI generation and gate drive stress in synchronous buck controllers. |
| UL Recognized #E-326243 | Confirms flammability compliance and electrical insulation integrity for use in safety-critical industrial power supplies. |
Applications
| Automotive DC-DC Converters | Industrial Snubber Circuits |
|---|---|
Use Scenario: 12V-to-48V bidirectional converter in 48V mild-hybrid vehicles. IC Role / Device Role / Timing Role: Freewheeling diode in synchronous buck-boost stage, clamping inductive kickback during high-side switch turn-off. Use Value: 400V VRRM and 180A IFSM prevent avalanche failure during load dump transients; AEC-Q101 ensures 15-year field reliability. | Use Scenario: RCD snubber network across IGBTs in motor drives operating at 15kHz switching frequency. IC Role / Device Role / Timing Role: Fast-recovery clamp diode absorbing turn-off energy from inductive loads. Use Value: 35ns trr limits snubber dissipation to <0.8W per cycle; dual-die layout avoids thermal runaway under repeated surges. |
| LED Driver Power Supplies | Uninterruptible Power Systems (UPS) |
Use Scenario: Secondary-side rectification in constant-current LED drivers for commercial street lighting. IC Role / Device Role / Timing Role: Output rectifier converting high-frequency AC from flyback transformer to regulated DC. Use Value: 1.300V VF at 10A reduces conduction loss by 12% vs. standard FRD alternatives, extending thermal margin in sealed enclosures. | Use Scenario: Input-stage rectification in online double-conversion UPS handling 3-phase 400VAC input. IC Role / Device Role / Timing Role: Center-tapped bridge leg supporting 20A continuous output with redundant path capability. Use Value: Dual-die isolation enables fault containment - single-die failure preserves 50% output capacity during maintenance windows. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar superfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2004TV1 | Same TO-247 package, 20A/400V, trr = 30ns, VF = 1.25V @ 10A - slightly faster but not AEC-Q101 qualified. | Preferred for industrial SMPS where automotive qualification is unnecessary and 5ns trr reduction improves light-load efficiency. | Select STTH2004TV1 when AEC-Q101 is not required and lower VF justifies sourcing from STMicroelectronics. |
| IXYS MUR2040CT | TO-247 package, 20A/400V, trr = 45ns, VF = 1.35V @ 10A - slower recovery, higher forward drop, AEC-Q101 not claimed. | Suitable for cost-sensitive 50–100kHz UPS designs where EMI filtering budget accommodates longer trr. | Choose MUR2040CT only if thermal margin exceeds 15°C and automotive compliance is excluded from BOM requirements. |
Compared with STTH2004TV1 and IXYS MUR2040CT, SF2005PTH uniquely combines AEC-Q101 qualification, 35ns trr, and 1.300V VF in a dual-die TO-247AD - making it the sole option for automotive-grade 400V rectification where reliability and thermal coupling are co-constrained.

FAQ
What is the maximum junction temperature rating for SF2005PTH?
The SF2005PTH 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 20A conduction when case temperature does not exceed 100°C, leveraging its 2.5°C/W RθJC. Derating curves in the official TSC datasheet confirm safe operation up to 150°C ambient with appropriate heatsinking.
Is SF2005PTH pin-compatible with SF2005PT?
Yes, SF2005PTH is mechanically and electrically identical to SF2005PT except for AEC-Q101 qualification - both share the same TO-247AD package, pinout (A1/A2/K), thermal characteristics, and electrical specifications. The "H" suffix denotes enhanced reliability screening per AEC-Q101, with no PCB layout changes required for migration from SF2005PT to SF2005PTH.
What is the reverse recovery time test condition for SF2005PTH?
The reverse recovery time (trr) of 35ns for SF2005PTH is measured under standardized conditions: IF = 0.5A, IR = 1.0A, reverse recovery current Irr = 0.25A, and TJ = 25°C. This test uses a half-sine waveform with specified di/dt and dv/dt, as defined in the TSC datasheet Figure 6 test circuit diagram.
Does SF2005PTH support center-tapped transformer configurations?
Yes, SF2005PTH is explicitly designed for center-tapped applications: its dual-die construction features isolated anodes (A1 and A2) and a common cathode (K), enabling direct implementation in full-wave rectifier topologies without external diode pairing. This configuration reduces board area by ~40% versus discrete solutions and eliminates mismatch-induced thermal imbalance.
What packaging and plating standards apply to SF2005PTH?
SF2005PTH uses TO-247AD (TO-3P) molding compound rated UL 94V-0, with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Each tube contains 30 units, and the device marking includes "SF2005PTH", green compound indicator "G", factory code "F", and date code "YWW" per TSC specification.
