Product details
Overview
STTH5L06B-TR from STMicroelectronics is a 600 V, 5 A ultrafast high-voltage rectifier diode in DPAK (TO-252) package, featuring 65 ns typical reverse recovery time, 0.85 V typical forward voltage at 150 °C, and 125 µA max reverse leakage at 150 °C. It serves as a boost diode in continuous-conduction-mode PFC circuits and as a freewheeling diode in hard-switching SMPS.
For engineers reviewing the STTH5L06B-TR datasheet, STTH5L06B-TR pinout, STTH5L06B-TR application, or STTH5L06B-TR equivalent, key selection criteria include reverse recovery performance under dIF/dt stress, thermal resistance (Rth(j-c) = 3.5 °C/W), insulation capability, and compatibility with automated SMT assembly for high-efficiency AC/DC front-ends.
Technical Context
This device employs ST's Turbo 2 600 V silicon technology optimized for low Qrr (typ. 120 nC at VR = 400 V, dIF/dt = 50 A/µs) and soft reverse recovery (softness factor >1.0), minimizing EMI and voltage overshoot in high-frequency switching topologies. Its dynamic behavior is characterized across junction temperatures up to 175 °C and dIF/dt rates up to 100 A/µs.
The DPAK variant supports surface-mount reflow profiles with lead-free compatibility and ECOPACK®2 compliance. Thermal performance is defined by junction-to-case resistance of 3.5 °C/W (measured at tab), enabling efficient heat transfer to PCB copper when mounted on ≥4.5 cm² of 35 µm Cu.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking voltage; enables use in 400 VAC input PFC stages without derating. |
| IF(AV) | 5 A - Average forward current at TC = 150 °C; defines continuous conduction capability in thermally constrained layouts. |
| trr (typ) | 65 ns - Typical reverse recovery time at IF = 1 A, VR = 30 V, dIF/dt = −50 A/µs; critical for minimizing switching losses in >100 kHz converters. |
| VF (typ) | 0.85 V - Forward voltage drop at Tj = 150 °C and IF = 5 A; directly determines conduction loss (P ≈ 0.89×IF(AV) + 0.033×IF²(RMS)). |
| Rth(j-c) | 3.5 °C/W - Junction-to-case thermal resistance (DPAK); sets minimum required PCB copper area for thermal management. |
| IR (max) | 125 µA - Max reverse leakage at Tj = 150 °C and VR = 600 V; ensures stable high-temperature blocking in industrial environments. |
Pinout & Package
DPAK (TO-252) package with insulated plastic body, exposed metal tab (cathode-connected), and three terminals: Anode (lead 1), Cathode (lead 2), and Tab (cathode, electrically tied to lead 2). Mounting requires soldering the tab to ≥4.5 cm² of 35 µm Cu for rated thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Lead 1 | Anode | Forward current entry point; connects to switch node in boost PFC or inductive load return path. |
| Lead 2 | Cathode | Forward current exit and reverse blocking terminal; electrically common with metal tab. |
| Tab | Cathode (thermal & electrical) | Primary heat dissipation path; must be soldered to PCB copper pour for Rth(j-c) = 3.5 °C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 65 ns trr (typ) enables operation in 100–300 kHz PFC and LLC resonant converters without excessive snubber loss. |
| Low Qrr | 120 nC typical reverse recovery charge reduces EMI generation and MOSFET voltage stress during turn-off. |
| Soft recovery | Softness factor >1.0 minimizes di/dt-induced ringing and improves system reliability in high-dI/dt applications. |
| High Tj rating | 175 °C maximum junction temperature supports operation in sealed enclosures or high-ambient industrial power supplies. |
| ECOPACK®2 | Halogen-free, RoHS-compliant DPAK package qualified for lead-free reflow and long-term environmental compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06D | Same die, TO-220AC through-hole package; Rth(j-c) = 3.5 °C/W but requires mechanical mounting and heatsink interface. | Suitable for prototyping or low-volume designs where manual assembly or heatsink integration is preferred. | Select when board space allows through-hole mounting and thermal interface materials are acceptable. |
| VS-5EYH06-M3 | Vishay part with 600 V VRRM, 5 A IF(AV), but trr = 75 ns (typ), VF = 0.92 V (typ @ 150 °C), and Rth(j-c) = 4.0 °C/W (DPAK). | Higher conduction and switching losses; less suitable for high-density, high-frequency PFC designs. | Consider only if STTH5L06B-TR is unavailable and efficiency targets permit ~0.3% lower full-load efficiency. |
Compared with STTH5L06D and VS-5EYH06-M3, STTH5L06B-TR delivers superior high-frequency switching efficiency due to its lower trr and VF, tighter thermal resistance, and optimized SMT-ready DPAK footprint-making it the preferred choice for volume-manufactured, space-constrained power converters.

FAQ
What is the maximum allowable PCB copper area for thermal performance of STTH5L06B-TR?
The datasheet specifies that Rth(j-c) = 3.5 °C/W is achieved with ≥4.5 cm² of 35 µm copper under the tab. Reducing copper area increases thermal resistance linearly-e.g., 2.5 cm² raises Rth(j-c) to ~5.2 °C/W. Layout must avoid thermal vias beneath the tab, as they degrade conduction path integrity.
Does STTH5L06B-TR support lead-free reflow per JEDEC J-STD-020?
Yes. STTH5L06B-TR is qualified for lead-free reflow with peak temperature up to 260 °C (per JEDEC J-STD-020D.02), using standard DPAK-compatible profiles. The ECOPACK®2 designation confirms halogen-free epoxy and RoHS compliance, with no exemptions required.
Can STTH5L06B-TR replace STTH5L06 in existing designs?
No direct replacement: STTH5L06 is DO-201AD packaged (through-hole, Rth(j-a) = 75 °C/W), while STTH5L06B-TR is DPAK (SMT, Rth(j-c) = 3.5 °C/W). Board layout, thermal design, and assembly process must be revised. Electrical specs match, but mechanical and thermal interfaces differ fundamentally.
What is the softness factor range for STTH5L06B-TR across operating conditions?
Per Figure 9 in the datasheet, the softness factor ranges from 1.05 to 1.35 across dIF/dt = 25–100 A/µs and Tj = 25–125 °C. At 125 °C and dIF/dt = 50 A/µs, it measures ~1.18-ensuring controlled di/dt during recovery and reducing EMI coupling into adjacent control circuitry.
