Product details
Overview
STTH3010WY from STMicroelectronics is an AEC-Q101-qualified ultrafast recovery high-voltage silicon rectifier diode in DO-247 package, rated for 1000 V repetitive peak reverse voltage, 30 A average forward current at Tc = 105 °C, and 42 ns typical reverse recovery time at IF = 1 A, dIF/dt = −200 A/µs, VR = 30 V, Tj = 25 °C. It delivers low conduction loss (VF typ. 1.30 V @ 30 A, 25 °C), soft recovery (S factor = 1), and high junction temperature capability up to 175 °C - deployed in automotive DC-DC converters and on-board chargers.
For engineers reviewing the STTH3010WY datasheet, STTH3010WY pinout, STTH3010WY application, or STTH3010WY equivalent, key selection criteria include verified ultrafast soft recovery performance, thermal robustness under pulsed high-current stress, conduction loss modeling via P = 1.3 × IF(AV) + 0.013 × IF²(RMS), and DO-247 mechanical compatibility with high-power heatsink mounting.
Technical Context
This diode employs a platinum-doped lifetime-controlled silicon structure enabling controlled carrier recombination for ultrafast and soft reverse recovery - critical for minimizing EMI and voltage overshoot in high-frequency switching topologies like phase-shifted full-bridge and LLC resonant converters. Its 1.1 °C/W junction-to-case thermal resistance (DO-247) supports sustained 30 A operation at Tc = 105 °C without derating.
The device exhibits stable dynamic behavior across temperature: trr increases only marginally from 42 ns (25 °C) to ~55 ns (125 °C) under identical test conditions, while IRM remains tightly bounded at 24–32 A at Tj = 125 °C, ensuring predictable snubber design and reduced stress on complementary MOSFETs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports 800 V DC bus designs with 20% safety margin against transients |
| IF(AV) | 30 A @ Tc = 105 °C - enables continuous power delivery in compact automotive power modules |
| trr (typ) | 42 ns @ IF = 1 A, dIF/dt = −200 A/µs - ensures minimal switching loss in >100 kHz converters |
| VF (typ) | 1.30 V @ 30 A, 25 °C - reduces conduction loss to ~39 W at full load using P = 1.3×IF + 0.013×IF² |
| Tj max | 175 °C - allows operation in under-hood environments without thermal shutdown |
| Rth(j-c) | 1.1 °C/W (DO-247) - enables direct bolt-down heatsinking for high-reliability thermal management |
| Softness factor | S = 1 - eliminates current tailing, suppressing voltage spikes and RFI during turn-off |
Pinout & Package
STTH3010WY uses the DO-247 through-hole package: a 3-lead, isolated metal-can package with center cathode tab, optimized for high-current conduction and mechanical robustness in automotive power stages. Mounting torque: 0.80 N·m (recommended), max 1.0 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to input DC bus or transformer secondary; must withstand 300 A surge (IFRM) |
| Cathode (Tab) | Forward current exit / heat path | Electrically and thermally connected to PCB heatsink; primary thermal interface (Rth(j-c) = 1.1 °C/W) |
| Anode (Lead 2) | Redundant anode connection | Parallel lead for lower inductance and higher pulsed current handling (IFSM = 180 A) |
Key Features

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 MUR3010CT | TO-247 package, dual common-cathode configuration; trr = 60 ns (typ), VF = 1.45 V @ 30 A | Requires dual-diode layout; higher VF increases conduction loss by ~11% at full load | Preferred where dual-output rectification is needed; less suitable for single-anode high-density layouts |
| Vishay VS-30EWH10 | DO-247 package, same pinout; trr = 45 ns (typ), VF = 1.35 V @ 30 A, Tj max = 175 °C | Identical mechanical fit; slightly higher VF and trr reduce efficiency margin in high-frequency designs | Drop-in replacement with minor trade-offs in softness and conduction loss; validated for AEC-Q101 but not explicitly automotive-marked |
Compared with MUR3010CT and VS-30EWH10, STTH3010WY offers the lowest trr (42 ns) and softest recovery (S = 1), making it optimal for EMI-sensitive automotive converters where voltage overshoot must be minimized - while maintaining identical DO-247 footprint and thermal performance.

FAQ
What is the maximum surge current rating for STTH3010WY?
The non-repetitive surge forward current (IFSM) is 180 A for a 10 ms sinusoidal pulse. This rating is validated per IEC 61000-4-5 and supports transient overload conditions in automotive power supplies without degradation. The device maintains parameter stability after such events when operated within its thermal limits.
Does STTH3010WY require a heatsink in standard operation?
Yes - at 30 A average forward current, junction temperature rises by 33 °C above case temperature (P ≈ 39 W × 1.1 °C/W). A properly mounted heatsink maintaining Tc ≤ 105 °C is mandatory. The DO-247 metal tab must be bolted to a thermally conductive surface with recommended torque of 0.80 N·m.
How does the softness factor of 1 impact circuit design?
A softness factor of 1 means no reverse recovery current tail - the diode transitions cleanly from conduction to blocking without oscillatory ringing. This eliminates the need for RC snubbers in most high-frequency topologies and reduces EMI filter complexity, especially critical in automotive EMC-compliant designs.
Is STTH3010WY pin-compatible with STTH3010GY?
No - STTH3010WY uses DO-247 (3-lead through-hole), while STTH3010GY uses D2PAK (surface-mount). Their footprints, thermal paths, and mounting methods differ fundamentally. Board redesign is required for substitution; electrical specs are closely matched but mechanical integration is not interchangeable.
