Product details
Overview
STTH6010WY from STMicroelectronics is an AEC-Q101-qualified ultrafast recovery high-voltage silicon diode in DO-247 package, rated for 1000 V repetitive peak reverse voltage, 60 A average forward current at Tc = 75 °C, and 49 ns typical reverse recovery time at IF = 1 A, dlF/dt = −200 A/µs, VR = 30 V, Tj = 25 °C. It delivers low conduction loss (VF typ. 1.3 V at Tj = 150 °C, IF = 60 A) and soft recovery (S = 1), making it suitable for automotive DC-DC converters and snubber circuits.
For engineers reviewing the STTH6010WY datasheet, STTH6010WY pinout, STTH6010WY application, or STTH6010WY equivalent, key selection criteria include ultrafast soft recovery behavior, high junction temperature capability (Tj max = 175 °C), low leakage (<20 µA at 25 °C), thermal resistance (Rth(j–c) = 0.78 °C/W), and AEC-Q101 qualification for under-hood power electronics.
Technical Context
This diode employs a planar epitaxial structure with optimized lifetime control to achieve ultrafast, soft reverse recovery-critical for minimizing EMI and voltage overshoot in high-frequency switching topologies. Its softness factor (S = 1) indicates near-zero minority carrier tail current, reducing switching stress on MOSFETs/IGBTs in bridge configurations.
Designed for high-reliability automotive applications, it operates across −40 to +175 °C junction temperature range and sustains 400 A non-repetitive surge current (tp = 10 ms sinusoidal). The DO-247 package enables direct heatsink mounting via M3 screw (0.80 N·m recommended torque), supporting conduction-cooled thermal management in space-constrained power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports 800 V DC bus systems with 20% safety margin for transient overvoltage |
| IF(AV) | 60 A at Tc = 75 °C - enables continuous operation in high-power auxiliary supplies without forced air cooling |
| trr (typ) | 49 ns - reduces turn-off losses in 100–500 kHz SMPS designs compared to standard fast recovery diodes |
| VF (typ) | 1.3 V at Tj = 150 °C, IF = 60 A - lowers conduction loss to ~78 W in worst-case thermal condition |
| Rth(j–c) | 0.78 °C/W - allows ≤120 °C junction rise above case at 60 A, compatible with aluminum heatsinks ≥100 cm² |
| Tj (max) | +175 °C - meets under-hood ambient requirements per ISO 16750-4 (125 °C ambient + 50 °C rise) |
| Softness (S) | 1 - eliminates reverse recovery tail, preventing secondary breakdown in synchronous rectification and IGBT freewheeling |
Pinout & Package
The STTH6010WY uses a 2-terminal DO-247 package with isolated metal tab (cathode-connected case), designed for direct thermal coupling to heatsinks. Mounting requires M3 screw with 0.80 N·m torque (max 1.0 N·m).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead) | Forward current entry point | Connected to low-side switch node in buck converters; must withstand 450 A peak pulsed current |
| Cathode (metal tab) | Forward current exit / heat path | Electrically tied to cathode; serves as primary thermal interface-requires insulated mounting if not referenced to system ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per Rev G |
| Ultrafast soft recovery | trr = 49 ns with S = 1 ensures minimal dv/dt-induced gate ringing in half-bridge motor drives |
| Low leakage current | <20 µA at 25 °C and <200 µA at 125 °C prevents thermal runaway in parallel-connected arrays |
| High junction temperature rating | 175 °C max Tj enables operation in engine compartment environments without derating |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant epoxy meets UL94 V0 flammability rating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast high-voltage diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MUR6010CT | TO-220AB package, dual common-cathode configuration; trr = 60 ns (typ), VF = 1.45 V @ 150 °C | Requires PCB layout redesign due to dual-diode footprint and higher VF increases conduction loss by ~11 W at 60 A | Select only when dual-diode topology or TO-220 mechanical compatibility is required |
| Vishay VS-60EWH10 | DO-247 package, same pinout; trr = 55 ns (typ), VF = 1.35 V @ 150 °C, no AEC-Q101 certification | Lacks automotive qualification-unsuitable for safety-critical or OEM-specified applications | Acceptable for industrial SMPS where AEC-Q101 is not mandated |
Compared with MUR6010CT and VS-60EWH10, STTH6010WY uniquely combines AEC-Q101 qualification, DO-247 thermal performance (Rth(j–c) = 0.78 °C/W), and softest recovery (S = 1), making it the only drop-in solution for automotive-grade 1000 V snubber and freewheeling roles requiring zero tail current.

FAQ
Is STTH6010WY pin-compatible with other DO-247 diodes?
Yes-STTH6010WY uses the standard DO-247 outline (per Table 6 in DocID018924 Rev 2) with 2-terminal configuration: anode lead and cathode metal tab. Mechanical dimensions match industry-standard DO-247 footprints, enabling direct replacement in existing heatsink-mount layouts without board rework.
What is the maximum recommended mounting torque for STTH6010WY?
The datasheet specifies a recommended torque of 0.80 N·m and a maximum torque of 1.0 N·m for the M3 mounting screw. Exceeding 1.0 N·m risks cracking the epoxy body or deforming the metal tab, compromising thermal contact and electrical isolation integrity.
Does STTH6010WY require a thermal pad or insulator when mounted to a heatsink?
Yes-the cathode tab is electrically connected to the cathode terminal. If the heatsink is grounded or at a different potential, a thermally conductive but electrically isolating pad (e.g., mica or ceramic) must be used. ST recommends silicone-based thermal interface materials compatible with ECOPACK®2 halogen-free construction.
How does softness factor S = 1 impact circuit design?
An S = 1 indicates ideal soft recovery with no minority-carrier tail current. This eliminates reverse recovery-induced voltage spikes and EMI, allowing reduction or removal of snubber capacitors in IGBT/MOSFET bridges and simplifying EMI filter design in automotive DC-DC converters operating above 100 kHz.
