Product details
Overview
STTH30RQ06L2Y-TR from STMicroelectronics is an AEC-Q101 qualified 600 V, 30 A ultrafast recovery rectifier diode in HU3PAK package, designed for secondary-side rectification in high-efficiency automotive power systems. It delivers typ. 1.45 V forward voltage at 15 A/150 °C, 30 ns max reverse recovery time, and operates up to +175 °C junction temperature-enabling use in on-board chargers and EV DC/DC converters.
For engineers reviewing the STTH30RQ06L2Y-TR datasheet, STTH30RQ06L2Y-TR pinout, STTH30RQ06L2Y-TR application, or STTH30RQ06L2Y-TR equivalent, key selection criteria include ultrafast trr (≤30 ns), low thermal resistance (Rth(j-c) = 0.7 °C/W), AEC-Q101 qualification, and HU3PAK mounting compatibility for high-power automotive thermal management.
Technical Context
This device implements ST's 600 V silicon planar ultrafast rectifier technology optimized for minimal switching and conduction losses in hard-switched topologies. Its soft recovery behavior (S-factor >1.0) and low Qrr (360 nC) reduce EMI and voltage overshoot during turn-off.
Rated for continuous operation from –40 °C to +175 °C, it supports high ambient environments typical of under-hood EV power electronics. The HU3PAK package enables direct copper-plate mounting with low Rth(j-c), critical for sustaining 30 A average forward current at TC = 120 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive reverse voltage up to 600 V, suitable for 400 V DC bus systems with margin. |
| IF(AV) | 30 A - Sustains 30 A average forward current at TC = 120 °C, enabling compact heatsink design. |
| trr (max) | 30 ns - Ultrafast recovery minimizes switching loss and ringing in 50–100 kHz DC/DC stages. |
| VF (typ.) | 1.45 V @ 15 A, 150 °C - Low forward drop reduces conduction loss and thermal stress in high-temp operation. |
| Rth(j-c) | 0.7 °C/W - Enables efficient heat transfer to heatsink, supporting high-power density layout. |
| IR (max) | 800 µA @ 150 °C, 600 V - Low leakage preserves efficiency and reliability in high-voltage hold-off conditions. |
| Tj range | –40 °C to +175 °C - Fully rated for automotive under-hood environments per AEC-Q101. |
Pinout & Package
Housed in a thermally enhanced HU3PAK surface-mount package (14.0 × 11.8 × 18.6 mm), featuring isolated drain pad and dual source terminals for low-inductance PCB layout and direct thermal coupling to copper planes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry | Connected to high-side switch node; requires low-inductance trace routing to minimize voltage spike. |
| Cathode (K) | Forward current exit / output rail | Primary power return path; bonded to large copper pour for thermal and current handling. |
| NC (x2) | No connect | Internal die attach points; must remain unconnected per datasheet to avoid parasitic coupling. |
Key Features

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 MUR3060CT | TO-247AC package; 600 V, 30 A; trr = 35 ns (max); Rth(j-c) = 1.0 °C/W | Requires larger heatsink footprint and lacks AEC-Q101 qualification | Preferred for industrial non-automotive designs where cost and legacy TO-247 layout compatibility are priorities |
| Vishay VS-30ETH06-M3 | TO-220AC package; 600 V, 30 A; trr = 45 ns (max); VF = 1.65 V @ 15 A/150 °C | Lower thermal performance and no PPAP support; limited to commercial-temperature applications | Suitable for cost-sensitive 125 °C-rated systems where ultrafast timing is secondary to BOM simplification |
Compared with MUR3060CT and VS-30ETH06-M3, STTH30RQ06L2Y-TR provides superior thermal resistance, tighter trr control, and full automotive qualification-making it the only option qualified for production in AEC-Q101-compliant EV power systems requiring 175 °C operation and PPAP documentation.

FAQ
What is the maximum allowable case temperature for continuous 30 A operation?
The datasheet specifies IF(AV) = 30 A at TC = 120 °C under square-wave conditions (δ = 0.5). Operation at higher case temperatures requires derating per Figure 1; at TC = 130 °C, maximum sustainable IF(AV) drops to ~27 A. Thermal design must ensure TC remains ≤120 °C for full-rated current.
Does STTH30RQ06L2Y-TR support synchronous rectification control?
No-it is a unidirectional ultrafast PN junction rectifier, not a MOSFET-based synchronous device. It operates passively and cannot be actively gated. For synchronous designs, ST offers dedicated SR controllers (e.g., STSR3) paired with compatible N-channel MOSFETs.
How does the HU3PAK package compare to D²PAK in thermal performance?
HU3PAK achieves Rth(j-c) = 0.7 °C/W versus ~1.2 °C/W for standard D²PAK due to its thicker copper leadframe, larger thermal pad area, and optimized internal bond wire geometry. This results in ~40% lower junction temperature rise at identical power dissipation and PCB copper area.
Is the NC pin electrically isolated or internally tied?
The two NC terminals are mechanically anchored to the die attach paddle but are not electrically connected to any active region. They serve only structural and thermal roles. ST's datasheet explicitly prohibits connection to circuit nodes; soldering them to ground or other nets may cause parametric shift or premature failure.
