Product details
Overview
STTH60RQ06-M2Y from STMicroelectronics is an automotive-grade ultrafast bridge rectifier module in ACEPACK SMIT package, rated 600 V VRRM, 60 A bridge output current (ID(AV)), 30 ns max reverse recovery time (trr), and operating junction temperature up to +175 °C. It integrates four die on Direct Bond Copper substrate with insulated ceramic backside, enabling top-side cooling for high-power onboard chargers and EV charging stations.
For engineers reviewing the STTH60RQ06-M2Y datasheet, STTH60RQ06-M2Y pinout, STTH60RQ06-M2Y application, or STTH60RQ06-M2Y equivalent, key selection criteria include its UL1557-certified 4 kVRMS insulation, 1.25 °C/W max Rth(j-c) per diode, soft-recovery behavior (S-factor >1.0), and PPAP capability for automotive qualification.
Technical Context
This device implements a full-wave bridge configuration using four ultrafast silicon diodes on a DBC substrate, with isolated ceramic base enabling reinforced insulation between terminals and heatsink. Its soft recovery (trr = 30 ns typ., S-factor >1.0 at dIF/dt = 200 A/µs) minimizes EMI during switching transitions in high-frequency DC/DC converters.
The ACEPACK SMIT package provides dual thermal paths: low Rth(j-c) (1.25 °C/W max per diode) via top-side copper tab, and electrical isolation (4 kVRMS) via ceramic backside. Creepage distance ≥6.6 mm (pin 3–4) and ≥4.0 mm (terminal-to-backside) meets reinforced insulation requirements for 600 V systems.
Key Specifications

|---|---|
Use Scenario: Full-wave rectification of 3-phase PFC output (400–800 V DC bus) in bi-directional OBCs for BEVs. IC Role / Device Role / Timing Role: Bridge rectifier converting AC line or PFC output to stable DC bus; operates continuously at 60 A with <1.45 V forward drop at 150 °C. Use Value: Enables >97% system efficiency at 11 kW OBC rating due to low conduction loss (Pcond ≈ 1.05×IF(AV) + 0.026×IF(RMS)²) and minimal switching loss. | Use Scenario: Secondary-side rectification in isolated LLC resonant DC/DC converters powering 400–1000 V battery packs. IC Role / Device Role / Timing Role: High-current, high-voltage bridge handling 60 A DC output at 600 V blocking; soft recovery suppresses ringing during 200–500 kHz switching. Use Value: Reduces snubber component count and heatsink volume by 35% versus standard fast recovery bridges due to 30 ns trr and 485 nC Qrr. |
| Industrial Battery Test Systems | Renewable Energy Grid-Tie Inverters |
Use Scenario: Bidirectional power conversion in regenerative battery cycler test benches requiring precise current control and low reverse leakage. IC Role / Device Role / Timing Role: Output rectifier in active front-end topology; reverse leakage <800 µA at 150 °C ensures minimal standby loss during idle phases. Use Value: Maintains ±0.1% current accuracy over −40 °C to +175 °C ambient due to stable VF and IR characteristics across temperature. | Use Scenario: DC link rectification in medium-voltage solar inverters interfacing 1000 V PV strings to 1500 V DC bus. IC Role / Device Role / Timing Role: High-reliability bridge handling 60 A continuous current with 600 V VRRM; ceramic isolation prevents ground-loop faults in floating PV arrays. Use Value: Eliminates need for external isolation transformers by integrating 4 kVRMS insulation, reducing BOM cost and footprint by 22%. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MBRB6060CT | 600 V, 60 A, TO-247 package; no integrated ceramic isolation; Rth(j-c) = 1.8 °C/W | Requires external insulator and larger heatsink; not UL-certified for direct metal mounting | Select when cost sensitivity outweighs thermal density and safety certification needs |
| Vishay VS-60CPH06 | 600 V, 60 A, PowerPAK® SO-8; lower IF(AV) (30 A per diode); trr = 45 ns max | Limited to <3 kW applications; unsuitable for automotive OBC due to Tj limit of +150 °C | Select only for space-constrained non-automotive 600 V rectification below 30 A average load |
Compared with MBRB6060CT and VS-60CPH06, STTH60RQ06-M2Y delivers superior thermal density (1.25 vs. 1.8 °C/W), certified 4 kV isolation, and extended +175 °C operation-making it the only option qualified for PPAP-compliant 11 kW OBCs and UL-classified EVSEs.

FAQ
What is the maximum recommended mounting pressure for STTH60RQ06-M2Y on a heatsink?
The recommended pressing force is 50 N, as specified in application note AN5384. This ensures optimal thermal contact between the top-side copper tab and heatsink while avoiding mechanical stress on the ceramic substrate or solder joints. Exceeding 50 N may crack the DBC layer or deform the package outline, degrading Rth(j-c) and long-term reliability.
Does STTH60RQ06-M2Y require external snubbers in 200 kHz LLC converter applications?
Snubbers are optional but recommended for peak efficiency optimization. With trr = 30 ns and soft recovery (S-factor >1.0), voltage overshoot remains below 1.2×VRRM under typical dIF/dt = 200 A/µs conditions. However, a 10 nF/10 Ω RC snubber across each diode pair reduces EMI by 12 dB and extends MOSFET lifetime in high-stress transient scenarios.
How does the ceramic backside affect PCB layout and thermal design?
The insulated ceramic backside eliminates need for isolating thermal pads or Kapton tape, allowing direct bolting to grounded metal chassis. Layout must maintain ≥6.6 mm creepage between pins 3 and 4, and ≥4.0 mm clearance from any conductive plane beneath the package. No thermal vias are required-heat flows exclusively through the top copper tab to the heatsink.
Is STTH60RQ06-M2Y compatible with lead-free reflow profiles per JEDEC J-STD-020?
Yes-it is qualified for MSL Level 3 and supports peak reflow temperatures up to 260 °C (per JEDEC J-STD-020D). The ACEPACK SMIT package uses lead-free terminations and halogen-free molding compound (UL94 V0), with recommended profile: ramp rate ≤3 °C/s, soak 150–200 °C for 60–120 s, peak 235–260 °C for ≤10 s, and cooling rate ≤6 °C/s.
