Product details
Overview
STTH60RQ06W from STMicroelectronics is a 600 V, 60 A ultrafast high-voltage rectifier diode in DO-247 package, designed for secondary rectification in HV LLC full-bridge topologies and high-voltage boost functions. It delivers soft recovery behavior (SFACTOR > 0.6 at 500 A/µs), low reverse leakage (≤160 µA at 150 °C), and low thermal resistance (Rth(j–c) = 0.38 °C/W), enabling efficient operation in industrial switching power supplies.
For engineers reviewing the STTH60RQ06W datasheet, STTH60RQ06W pinout, STTH60RQ06W application, or STTH60RQ06W equivalent, key selection criteria include trr ≤ 35 ns at 25 °C, VF ≤ 1.45 V at 60 A / 150 °C, junction temperature rating up to 175 °C, and DO-247 mechanical compatibility with high-power heatsink mounting.
Technical Context
This ultrafast silicon rectifier employs optimized carrier lifetime control to achieve soft reverse recovery (SFACTOR ≥ 0.6 across dIF/dt = 50–500 A/µs) and low Qrr (660 nC typical). Its design targets high-frequency, high-efficiency HV DC–DC conversion where voltage overshoot and EMI from hard switching must be minimized.
Thermal performance is engineered for conduction-dominated loss scenarios: Rth(j–c) = 0.38 °C/W enables sustained 60 A average forward current at TC = 115 °C with δ = 0.5 square waveform, while IF(RMS) rating reaches 90 A in DO-247 configuration.
Key Specifications

|---|---|
| VRRM | 600 V - Withstands repetitive reverse voltage up to 600 V, suitable for 400 V bus systems with safety margin. |
| IF(AV) | 60 A - Sustained average forward current at TC = 115 °C, δ = 0.5, defining continuous rectification capability. |
| VF(max) | 1.45 V - Maximum forward voltage at 60 A and 150 °C, directly determining conduction loss (Pcond ≈ IF × VF). |
| trr(max) | 35 ns - Maximum reverse recovery time at 25 °C, 0.5 A IF, critical for minimizing switching loss in >100 kHz converters. |
| Rth(j–c) | 0.38 °C/W - Junction-to-case thermal resistance, enabling precise heatsink sizing for thermal management. |
| Qrr | 660 nC - Reverse recovery charge at 125 °C, 60 A IF, 400 V VR, used to calculate turn-off energy loss. |
| Tj(max) | 175 °C - Maximum allowable junction temperature, supporting operation in high-ambient industrial environments. |
Pinout & Package
STTH60RQ06W uses the DO-247 through-hole package: an insulated, high-thermal-conductivity metal-can package with two leads (anode and cathode), rated for 0.8 N·m recommended mounting torque and UL94 V0 epoxy encapsulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to high-side switch node or transformer secondary winding; carries full load current during conduction phase. |
| Cathode (Lead 2) | Forward current exit point | Connected to output rail or ground return path; serves as reference for reverse voltage blocking and freewheeling paths. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast soft recovery | SFACTOR ≥ 0.6 across dIF/dt = 50–500 A/µs, reducing voltage overshoot and EMI in high-dV/dt circuits. |
| High-temperature operation | Tj(max) = 175 °C with stable VF and IR performance up to 150 °C, enabling compact thermal design. |
| Low thermal resistance | Rth(j–c) = 0.38 °C/W supports high-power density layouts without derating at elevated case temperatures. |
| ECOPACK2 compliance | Meets RoHS and halogen-free requirements per ST's environmental standard, with full traceability. |

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-die common-cathode configuration; VF = 1.75 V @ 60 A/125 °C; trr = 45 ns. | Requires dual-channel layout; higher VF increases conduction loss by ~21% at full load. | Preferred when dual-diode integration simplifies board routing, accepting higher thermal dissipation. |
| Vishay VS-60EPU06 | DO-247 package, single-diode; VF = 1.55 V @ 60 A/125 °C; trr = 40 ns; Rth(j–c) = 0.45 °C/W. | Higher thermal resistance requires larger heatsink area; slightly slower recovery increases EMI filtering burden. | Valid drop-in replacement if existing thermal design has ≥15% margin, but not recommended for 300+ kHz operation. |
Compared with MUR6060CT and VS-60EPU06, STTH60RQ06W offers the lowest combined conduction–switching loss profile (VF × trr = 1.45 V × 35 ns) and best thermal interface (0.38 °C/W), making it optimal for space-constrained, high-frequency industrial power stages.

FAQ
What is the maximum recommended mounting torque for STTH60RQ06W?
The DO-247 package specifies a recommended torque value of 0.8 N·m and a maximum torque of 1.0 N·m. Exceeding 1.0 N·m risks mechanical damage to the leadframe or epoxy seal, compromising thermal performance and long-term reliability under thermal cycling.
Does STTH60RQ06W support parallel operation for higher current handling?
Yes-STTH60RQ06W exhibits positive thermal coefficient of VF, enabling inherently balanced current sharing when paralleled with identical units. Designers must match layout symmetry, thermal coupling, and use Kelvin-sense traces to avoid imbalance from parasitic inductance differences.
How does soft recovery behavior reduce EMI in high-frequency converters?
Soft recovery (SFACTOR ≥ 0.6) limits di/dt during turn-off, suppressing high-frequency ringing caused by LC resonance between stray inductance and junction capacitance. This reduces conducted EMI above 30 MHz and eases compliance with CISPR 11 Class A limits without oversized snubbers.
Is STTH60RQ06W suitable for use in synchronous rectification topologies?
No-it is a unidirectional rectifier diode, not a synchronous MOSFET. However, its low Qrr and soft recovery make it ideal as a freewheeling or clamping diode alongside synchronous FETs, where it absorbs reverse recovery energy without inducing voltage spikes that could falsely trigger gate drivers.
