Product details
Overview
STTH60RQ06WL from STMicroelectronics is a 600 V, 60 A ultrafast high-voltage rectifier diode in DO-247 LL package, designed for secondary rectification in HV LLC full-bridge topologies and high-voltage boost functions. It delivers soft recovery behavior (SFACTOR > 0.8 at 500 A/µs), low reverse current (160 µA at 150 °C), and low thermal resistance (Rth(j–c) = 0.38 °C/W), enabling high-efficiency power conversion in industrial switching supplies.
For engineers reviewing the STTH60RQ06WL datasheet, STTH60RQ06WL pinout, STTH60RQ06WL application, or STTH60RQ06WL equivalent, key selection criteria include reverse recovery time (trr ≤ 35 ns at 25 °C), forward voltage drop (VF ≤ 1.45 V at 60 A / 150 °C), junction temperature rating (Tj(max) = 175 °C), and DO-247 LL mechanical compatibility with high-power thermal mounting.
Technical Context
This ultrafast silicon rectifier employs optimized carrier lifetime control to achieve soft reverse recovery-critical for minimizing EMI and voltage overshoot in resonant converters. Its dynamic performance is characterized by low Qrr (660 nC typical) and controlled IRM (12–16 A), enabling reliable operation under high dIF/dt conditions (up to 500 A/µs).
The device supports dual-package variants: DO-247 (90 A RMS) and DO-247 LL (80 A RMS), both rated for Tj = 175 °C and featuring UL94 V0 epoxy. Thermal management relies on conduction cooling via case-mounting, with specified torque (0.8 N·m recommended) and mechanical dimensions validated per Table 6.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive reverse voltage up to 600 V without breakdown, suitable for 400 V DC bus systems with margin. |
| IF(AV) | 60 A - Average forward current at TC = 115 °C with 50% duty cycle, defining continuous conduction capability in rectifier applications. |
| VF(max) | 1.45 V - Maximum forward voltage at 60 A and 150 °C, directly determining conduction loss (Pcond ≈ IF × VF) in high-temp operation. |
| trr(max) | 35 ns - Maximum reverse recovery time at 25 °C, 0.5 A IF, 1 A IR, ensuring fast turn-off and reduced switching loss in MHz-range SMPS. |
| Rth(j–c) | 0.38 °C/W - Junction-to-case thermal resistance, enabling accurate heatsink sizing for thermal design at 80–90 W dissipation. |
| Tj(max) | 175 °C - Maximum allowable junction temperature, supporting operation in harsh industrial environments without derating. |
| Qrr | 660 nC - Typical reverse recovery charge at 125 °C, 60 A IF, 400 V VR, used to calculate turn-off energy loss in hard-switched topologies. |
Pinout & Package
STTH60RQ06WL uses a 2-terminal DO-247 LL (Long Lead) package optimized for high-current conduction cooling. The case serves as the cathode terminal, and the lead is the anode. Mounting requires torque-controlled screw attachment (0.8 N·m recommended) to ensure low thermal impedance and mechanical reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead) | Forward current entry point | Carries full load current into the P+–N– junction; must be routed with low-inductance layout to minimize voltage spikes during recovery. |
| Cathode (case) | Forward current exit / heat path | Electrically and thermally connected to heatsink; serves as primary thermal interface and return path-requires clean, flat mounting surface. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast soft recovery | SFACTOR > 0.8 across dIF/dt range (50–500 A/µs), reducing EMI and snubber stress in LLC resonant converters. |
| High junction temperature rating | 175 °C maximum operating temperature enables use in enclosed industrial enclosures without forced air cooling. |
| Low thermal resistance | Rth(j–c) = 0.38 °C/W allows ≥80 W power dissipation with ≤30 °C case-to-ambient delta under proper heatsinking. |
| ECOPACK2 compliance | Meets RoHS and halogen-free requirements per ST's environmental standard, supporting green manufacturing and export compliance. |
| Reduced conduction losses | VF ≤ 1.45 V @ 60 A / 150 °C lowers average conduction loss by ~12% vs. legacy 600 V rectifiers with VF > 1.6 V. |
Applications
| Industrial Switching Power Supplies | HV LLC Resonant Converters |
|---|---|
Use Scenario: High-efficiency 3–5 kW AC/DC front-end rectification with active PFC and isolated DC/DC stage. IC Role / Device Role / Timing Role: Secondary-side ultrafast rectifier in synchronous or asymmetrical half-bridge output stage. Use Value: Soft recovery minimizes voltage ringing across transformer secondary, reducing EMI filter size and improving efficiency above 95%. | Use Scenario: Output rectification in 1–3 kW server PSU or telecom rectifier using HV LLC topology. IC Role / Device Role / Timing Role: High-voltage freewheeling diode clamping resonant tank voltage during dead-time intervals. Use Value: trr ≤ 35 ns ensures zero-voltage switching (ZVS) integrity at 300–500 kHz, preventing body-diode conduction in synchronous MOSFETs. |
| High-Voltage Boost PFC | Industrial Motor Drive Snubbers |
Use Scenario: Boost diode in 800 V DC-link PFC stage for factory automation drives and renewable inverters. IC Role / Device Role / Timing Role: Unidirectional current path sustaining 600 V reverse blocking while conducting 60 A peak current. Use Value: Low Qrr (660 nC) reduces turn-off loss during 20–100 kHz switching, improving PFC efficiency by 0.3–0.5% at full load. | Use Scenario: Clamping diode in IGBT-based 3-phase inverter leg for regenerative braking and overvoltage suppression. IC Role / Device Role / Timing Role: Fast-recovery clamp protecting IGBT collector-emitter during inductive load commutation. Use Value: IRM ≤ 16 A and soft recovery limit voltage overshoot to < 10% above VRRM, eliminating need for TVS supplementation. |
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, 600 V/60 A, trr = 50 ns (max), VF = 1.7 V (max) at 60 A/150 °C | Higher VF increases conduction loss by ~17%; larger Rth(j–c) (0.55 °C/W) limits power density | Prefer when existing TO-247 heatsink infrastructure exists and soft recovery is less critical than cost. |
| Vishay VS-60EPU06 | DO-247 package, 600 V/60 A, trr = 45 ns (max), VF = 1.55 V (max) at 60 A/150 °C, no SFACTOR spec | Moderate softness; lacks published softness factor curves, limiting confidence in EMI-sensitive resonant designs | Select where LLC topology is not used and thermal budget allows higher VF-related loss. |
Compared with MUR6060CT and VS-60EPU06, STTH60RQ06WL offers superior soft recovery (SFACTOR > 0.8), lower VF (1.45 V), and lower Rth(j–c) (0.38 °C/W), making it optimal for high-frequency, high-efficiency resonant and PFC applications demanding minimal EMI and thermal headroom.

FAQ
What is the difference between STTH60RQ06W and STTH60RQ06WL?
STTH60RQ06W uses the standard DO-247 package (90 A RMS rating), while STTH60RQ06WL uses the DO-247 LL (Long Lead) variant with modified lead geometry and 80 A RMS rating. The LL version features extended leads for improved mechanical stability in high-vibration environments and slightly different thermal mounting characteristics due to altered case contact area.
Can STTH60RQ06WL replace STTH60R06 in existing designs?
No-STTH60R06 is a 600 V/60 A fast recovery diode with trr ≈ 75 ns and VF ≈ 1.7 V, lacking soft recovery and rated only to 150 °C junction temperature. STTH60RQ06WL's 35 ns trr, soft recovery, and 175 °C rating enable higher-frequency operation but require validation of layout parasitics and thermal interface due to tighter timing margins.
Is STTH60RQ06WL suitable for synchronous rectification?
No-it is a unidirectional silicon PN junction rectifier, not a MOSFET-based synchronous rectifier. It cannot be actively gated. However, its ultrafast soft recovery makes it ideal as a freewheeling or clamping diode alongside synchronous MOSFETs in hybrid topologies where body-diode conduction must be avoided.
What torque value should be used when mounting STTH60RQ06WL?
The recommended mounting torque is 0.8 N·m for the DO-247 LL package. Exceeding the maximum torque of 1.0 N·m may deform the case or compromise internal bond wire integrity. Consistent torque application ensures repeatable thermal resistance and mechanical reliability across production units.
