Product details
Overview
STTH3010GY-TR from STMicroelectronics is an AEC-Q101-qualified ultrafast recovery high-voltage silicon rectifier diode in D2PAK (TO-263) 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 at Tj = 150 °C, IF = 30 A) and soft recovery for reduced EMI in automotive power converters.
For engineers reviewing the STTH3010GY-TR datasheet, STTH3010GY-TR pinout, STTH3010GY-TR application, or STTH3010GY-TR equivalent, key selection criteria include junction-to-case thermal resistance (1.1 °C/W), surge capability (180 A IFSM), softness factor ≥1, and ECOPACK®2 compliance - all critical for high-reliability 12 V/42 V automotive DC-DC stages and alternator rectification.
Technical Context
This diode employs planar passivated silicon technology optimized for ultrafast soft recovery, minimizing reverse recovery current (IRM = 24–32 A at IF = 30 A, dIF/dt = −200 A/µs, VR = 600 V, Tj = 125 °C) and associated switching losses. Its rugged junction design supports continuous operation up to 175 °C junction temperature and withstands repetitive 300 A peak forward current (tp = 5 µs, F = 5 kHz square).
The device's dynamic behavior is characterized by a softness factor ≥1 across dIF/dt range (0–500 A/µs) and stable trr variation with temperature - enabling predictable snubberless operation in high-frequency (>100 kHz) boost PFC and motor drive freewheeling paths where voltage overshoot control is essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands 1 kV reverse bias in automotive load-dump transients without breakdown |
| IF(AV) | 30 A at Tc = 105 °C - Sustains continuous forward current in thermally constrained engine-bay PCB layouts |
| trr (typ) | 42 ns - Enables efficient >150 kHz switching in isolated DC-DC converters with minimal turn-off loss |
| VF (typ) | 1.30 V at Tj = 150 °C, IF = 30 A - Reduces conduction loss to ~39 W (P ≈ 1.3×IF + 0.013×IF²) at full rating |
| Rth(j-c) | 1.1 °C/W - Allows 30 A operation with ≤33 °C junction-to-case temperature rise under forced convection |
| IRM (max) | 32 A - Limits voltage spike during fast turn-off in inductive loads (e.g., solenoid drivers) |
| S factor | ≥1 - Ensures soft, non-oscillatory reverse recovery to suppress EMI in EMC-sensitive vehicle networks |

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 |
|---|---|---|---|
| STTH3010WY | Same die, DO-247 through-hole package; Rth(j-c) = 1.1 °C/W but higher mounting torque (0.8 N·m) and larger footprint | Better suited for prototyping or high-vibration environments where mechanical retention is critical | Select when board-level reliability under shock/vibe exceeds thermal density requirements |
| IXYS MUR3010CT | 30 A/1000 V ultrafast diode in TO-220AB; trr = 60 ns (typ), VF = 1.45 V (typ), Rth(j-c) = 1.5 °C/W | Higher conduction and switching loss; requires larger heatsink in same 30 A application | Choose only if legacy TO-220 footprint compatibility is mandatory and efficiency penalty is acceptable |
Compared with STTH3010WY and MUR3010CT, STTH3010GY-TR offers superior thermal performance in surface-mount form factor and lower EMI due to tighter trr distribution and softness - making it optimal for space-constrained, high-frequency automotive power modules.

FAQ
Is STTH3010GY-TR pin-compatible with STTH3010WY?
No - STTH3010GY-TR uses a 3-pin D2PAK (TO-263) surface-mount package with cathode tab and lead, while STTH3010WY uses a 3-lead DO-247 through-hole package. Footprint, soldering method, and mechanical mounting differ significantly; PCB redesign is required for substitution.
What is the maximum allowable case temperature for continuous 30 A operation?
The datasheet specifies IF(AV) = 30 A at Tc = 105 °C for the D2PAK package. Exceeding this case temperature risks exceeding the 175 °C absolute maximum junction temperature, especially under high ambient or poor PCB copper area. Derating is required above 105 °C case temperature.
Does STTH3010GY-TR support paralleling for higher current?
Yes, but with strict layout constraints: matched trace inductance, symmetrical thermal coupling, and individual current-sense resistors are required. Its low IR (≤100 µA at 125 °C) improves current sharing stability, though thermal runaway risk remains without active balancing.
Can STTH3010GY-TR be used in non-automotive industrial applications?
Yes - its 1000 V VRRM, 175 °C Tj, and ultrafast soft recovery make it suitable for industrial SMPS, UPS systems, and welding equipment. However, AEC-Q101 qualification is not required outside automotive; alternative industrial-grade diodes may offer cost advantages if automotive reliability testing is unnecessary.
