Product details
Overview
STTH60L06W from STMicroelectronics is an ultrafast high-voltage silicon rectifier diode in DO-247 package, rated for 600 V repetitive peak reverse voltage, 60 A average forward current, and 70 ns maximum reverse recovery time. It serves as a discontinuous-mode PFC boost diode and free-wheeling diode in industrial switching power supplies, leveraging low 0.95 V typical forward voltage at 150 °C to minimize conduction losses.
For engineers reviewing the STTH60L06W datasheet, STTH60L06W pinout, STTH60L06W application, or STTH60L06W equivalent, key selection criteria include thermal resistance (0.75 °C/W), soft reverse recovery (S factor >1.0), surge capability (600 A IFSM), and low leakage (160 µA at 150 °C).
Technical Context
This device implements ST's Turbo 2 technology to achieve ultrafast switching with controlled soft recovery-critical for reducing EMI and voltage overshoot in high-frequency PFC stages. Its low VF and low trr enable high efficiency in both continuous and discontinuous conduction mode topologies.
The diode operates up to 175 °C junction temperature and exhibits stable dynamic performance across temperature: trr increases only ~1.4× from 25 °C to 125 °C, while IRM remains bounded at 19 A under 100 A/µs dIF/dt at 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input rectification in 400 VAC industrial SMPS and PFC front-ends without derating |
| IF(AV) | 60 A at Tc = 110 °C - enables high-power output stage operation with standard heatsinking |
| trr (max) | 70 ns - ensures minimal switching loss and reduced snubber requirements at 100 kHz+ PFC frequencies |
| VF (typ) | 0.95 V at IF = 60 A, Tj = 150 °C - lowers conduction loss by ~15% vs. legacy 1.1 V diodes at full load |
| Rth(j-c) | 0.75 °C/W - allows direct case-mounting to heatsink for predictable thermal design in enclosed industrial enclosures |
| IRM (max) | 19 A at dIF/dt = 100 A/µs - limits voltage spike during fast turn-off in hard-switched boost converters |
| Qrr | ~3.5 µC at dIF/dt = 100 A/µs, VR = 400 V - reduces capacitive energy dissipation in gate driver circuits |
Pinout & Package
DO-247 package: axial leaded, epoxy-molded, UL94 V0 compliant, designed for conduction cooling via case mounting. Mounting torque: 0.55–1.0 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (K) | Forward current entry terminal | Connected to switch node in boost PFC; must handle 600 A surge without bond-wire fusing |
| Cathode (A) | Forward current exit / reverse-blocking terminal | Connected to DC bus; withstands 600 V transient spikes and 160 µA leakage at 150 °C |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast soft recovery | S factor >1.0 at 100 A/µs ensures low EMI and reduced voltage overshoot in hard-switched PFC |
| Low thermal resistance | 0.75 °C/W junction-to-case enables compact thermal design without forced air in industrial 3 kW systems |
| High surge rating | 600 A non-repetitive surge (10 ms) supports cold-start inrush and line-dip recovery without failure |
| Low leakage at high temperature | 160 µA max reverse current at 150 °C maintains system efficiency in sealed, high-ambient environments |
Applications
| Industrial Switch-Mode Power Supply | PFC Boost Stage |
|---|---|
Use Scenario: 3 kW telecom rectifier operating at 100 kHz with 400 VAC input. IC Role / Device Role / Timing Role: Main output rectifier handling 60 A DC output current with <70 ns recovery to limit switching loss. Use Value: 0.95 V VF at 150 °C reduces conduction loss by 4.2 W vs. 1.15 V alternative, improving overall efficiency by 0.3%. | Use Scenario: Discontinuous conduction mode (DCM) PFC in factory automation drive. IC Role / Device Role / Timing Role: Boost diode conducting only during MOSFET off-time; requires soft recovery to suppress ringing.

IC Role / Device Role / Timing Role: Free-wheeling diode across IGBT collector-emitter, conducting reverse current during PWM dead-time. Use Value: 70 ns trr prevents shoot-through risk and reduces voltage stress on IGBTs during commutation. |
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 |
|---|---|---|---|
| IXYS MUR6060CT | TO-247 package, dual common-cathode configuration; VF = 1.75 V (typ) at 25 °C, trr = 65 ns | Requires dual-diode layout; higher VF increases conduction loss in high-temp operation | Prefer when dual-diode topology is required and thermal margin exists |
| Vishay VS-60EPU06 | TO-220AC package; VF = 1.15 V (typ) at 150 °C; Rth(j-c) = 1.2 °C/W | Larger thermal resistance limits power density; not suitable for conduction-cooled designs | Choose only where TO-220 mechanical fit is mandatory and airflow is guaranteed |
Compared with MUR6060CT and VS-60EPU06, STTH60L06W delivers superior thermal performance (0.75 °C/W), lower high-temperature VF (0.95 V), and DO-247 package compatibility with high-current PCB layouts-making it optimal for space-constrained, conduction-cooled industrial PFC and SMPS designs.

FAQ
What is the maximum junction temperature and how does it affect reliability?
The STTH60L06W has a maximum operating junction temperature of 175 °C. At this limit, reverse leakage remains within spec (1600 µA max), and VF drift is controlled-enabling extended lifetime in sealed industrial enclosures. Derating is not required up to 150 °C junction, where conduction loss stays below 6.5 W at 60 A.
Can STTH60L06W replace older STTH6006 diodes in existing designs?
Yes-STTH60L06W is a direct replacement for STTH6006 with identical DO-247 footprint and improved specs: lower VF (0.95 V vs. 1.15 V at 150 °C), same trr (70 ns), and higher IFSM (600 A vs. 400 A). No layout or thermal redesign is needed, and efficiency improves by ~0.4% at full load.
Is the DO-247 package compatible with automated through-hole assembly?
Yes-the DO-247 package uses axial leads with defined pitch (L3 = 14.2–14.8 mm) and lead diameter (Dia = 3.55–3.65 mm), supporting standard wave soldering and selective soldering processes. Lead coplanarity and torque specs (0.55–1.0 N·m) ensure robust mechanical attachment in high-vibration environments.
How does soft recovery (S factor) impact EMI in PFC circuits?
A soft recovery S factor >1.0 means reverse current decay is gradual-not abrupt-reducing high-frequency spectral content in switching node waveforms. In 100 kHz DCM PFC, this cuts conducted EMI by 8–10 dB above 30 MHz, often eliminating Class B filter components and simplifying EMC certification.
