Product details
Overview
STTH602CSF from STMicroelectronics is a dual 3 A ultrafast rectifier diode in PSMC (TO-277A) package, rated for 200 V repetitive peak reverse voltage, 24 ns typical reverse recovery time, and 0.80 V typical forward voltage at 125 °C - optimized for secondary-side rectification in high-efficiency DC/DC converters and LED lighting drivers.
For engineers reviewing the STTH602CSF datasheet, STTH602CSF pinout, STTH602CSF application, or STTH602CSF equivalent, key selection criteria include conduction loss modeling (P = 0.80 × IF(AV) + 0.040 × IF²(RMS)), thermal impedance (Rth(j-c) = 2.14 °C/W), surge rating (55 A IFSM), and junction temperature capability up to 175 °C.
Technical Context
This dual ultrafast rectifier integrates two independent 3 A diodes in a single PSMC (TO-277A) thermally enhanced surface-mount package with common cathode configuration. Its 24 ns trr (typ.) and soft recovery behavior (SFACTOR ≈ 0.3–0.5 at dIF/dt = 200 A/µs) minimize switching noise and EMI in high-frequency power stages.
The device operates across –65 °C to +175 °C junction range, supports 6 A total average forward current (3 A per diode at Tc = 155 °C), and delivers low VF drift over temperature - 0.80 V (typ.) at 125 °C and 3 A - enabling stable efficiency in thermally constrained LED driver and isolated converter designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - withstands 200 V repetitive reverse voltage without breakdown, suitable for 12–48 V output DC/DC converters with margin |
| IF(AV) per diode | 3 A at Tc = 155 °C - continuous forward current rating per die, enabling 6 A dual-channel operation with shared thermal path |
| trr (typ.) | 24 ns at 25 °C - ultrafast recovery minimizes reverse recovery loss and ringing in >100 kHz switching topologies |
| VF (typ.) | 0.80 V at 125 °C / 3 A - low conduction drop reduces power loss and thermal stress in high-current LED string drivers |
| Tj (max.) | +175 °C - extended junction temperature enables operation in sealed, high-ambient lighting enclosures or industrial power supplies |
| Rth(j-c) | 2.14 °C/W - low thermal resistance allows direct PCB copper pad heatsinking, supporting compact layout without external heatsinks |
Pinout & Package
STTH602CSF uses the PSMC (TO-277A) surface-mount package: thermally optimized epoxy case with exposed metal tab for conduction cooling, UL94 V0 rated, footprint dimensions 6.5 mm × 4.6 mm × 1.1 mm (L × W × H), and integrated dual-diode structure with common cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Input terminal for first diode | Accepts forward current into first rectifying path; electrically isolated from A2 |
| Anode 2 (A2) | Input terminal for second diode | Accepts forward current into second rectifying path; electrically isolated from A1 |
| Cathode (K) | Common output node | Shared cathode connection for both diodes - enables dual-output or interleaved rectification with single return path |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 24 ns trr (typ.) enables use in 200–500 kHz DC/DC converters without excessive switching loss or snubber requirements |
| Low VF temperature stability | 0.80 V (typ.) at 125 °C / 3 A ensures predictable conduction loss across full operating range |
| High surge robustness | 55 A non-repetitive surge rating (tp = 10 ms) protects against inrush and transient overload in LED driver startup |
| ECOPACK2 compliance | Meets RoHS, halogen-free, and lead-free soldering requirements for industrial and lighting applications |
Applications
| LED Constant-Current Driver | Isolated Flyback Converter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R02DJF | Single-die 8 A device in TO-252, higher IF(AV) but no dual-anode isolation; trr = 25 ns | Suitable for single-output, higher-current rectification; lacks independent anode separation | Select when needing higher per-path current and simpler layout, not dual-path isolation |
| MBR20200CT | Dual Schottky in TO-220AC, 200 V VRRM, 20 A total, VF ≈ 0.95 V @ 25 °C but degrades rapidly above 100 °C | Better low-temp VF but limited to ≤125 °C operation; higher IR leakage at elevated temperature | Select only for ambient < 85 °C applications where lowest room-temp VF is critical |
Compared with STTH8R02DJF and MBR20200CT, STTH602CSF uniquely balances dual-anode isolation, 175 °C operation, and stable VF across temperature - making it optimal for thermally demanding, multi-rail LED and industrial DC/DC designs where layout flexibility and thermal headroom are prioritized.

FAQ
What is the thermal resistance from junction to case (Rth(j-c)) for STTH602CSF?
The junction-to-case thermal resistance is 2.14 °C/W (typical), measured under steady-state conditions with proper mounting to a copper heatsink pad. This value enables accurate thermal modeling when designing PCB copper area for conduction cooling - no external heatsink required for ≤3 A per diode at 155 °C case temperature.
Does STTH602CSF support common-cathode or common-anode configuration?
STTH602CSF uses a common-cathode configuration: two independent anodes (A1, A2) share a single cathode (K) terminal. This supports dual-output rectification, interleaved operation, or redundancy schemes without cross-conduction risk between channels.
What is the maximum reverse recovery current (IRM) under worst-case conditions?
At Tj = 125 °C, IF = 3 A, dIF/dt = –200 A/µs, and VR = 160 V, the peak reverse recovery current is 4.8 A (typical). This value is critical for snubber design and MOSFET voltage stress analysis in high-dI/dt flyback or LLC resonant converters.
Is STTH602CSF compatible with lead-free reflow soldering processes?
Yes - STTH602CSF is ECOPACK2 compliant and qualified for standard lead-free reflow profiles (JEDEC J-STD-020), including peak temperatures up to 260 °C. The PSMC (TO-277A) package uses halogen-free epoxy and meets RoHS Directive 2011/65/EU requirements.
