Product details
Overview
STTH15RQ06WY from STMicroelectronics is an AEC-Q101-qualified ultrafast high-voltage rectifier diode in DO-247 package, rated for 600 V repetitive peak reverse voltage, 15 A average forward current, and 25 ns maximum reverse recovery time at 25 °C. It delivers soft recovery behavior, low thermal resistance (1.5 °C/W junction-to-case), and operates up to 175 °C junction temperature-designed for LLC full-bridge secondary rectification in automotive and industrial power supplies.
For engineers reviewing the STTH15RQ06WY datasheet, STTH15RQ06WY pinout, STTH15RQ06WY application, or STTH15RQ06WY equivalent, key selection criteria include its 600 V VRRM rating across -40 °C to +175 °C, 1.45 V max VF at 15 A/150 °C, 5.38 mm creepage (D²PAK HV variant), AEC-Q101 qualification, and DO-247 mechanical robustness with 0.8 N·m recommended mounting torque.
Technical Context
This device is a planar epitaxial silicon ultrafast recovery diode optimized for high-frequency switching topologies including LLC resonant converters and PFC stages. Its soft recovery (S-factor >1.0) minimizes EMI and voltage overshoot during turn-off, while low QRR (250 nC typical) and controlled dIF/dt dependence reduce switching losses in hard-switched and zero-voltage-switching circuits.
Thermal performance is enabled by low Rth(j-c) = 1.5 °C/W and operation up to Tj = 175 °C, supporting compact heatsink designs in space-constrained automotive and industrial environments. The DO-247 package provides enhanced creepage and mechanical stability versus TO-220AC, with UL94 V0 epoxy and 4.40 g mass.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Guarantees reliable blocking under transient overvoltage in 400–600 V DC bus applications (e.g., EV charging, UPS). |
| IF(AV) | 15 A at TC = 115 °C - Supports continuous conduction mode rectification in 500–1000 W power stages without forced air cooling. |
| trr (max) | 25 ns at Tj = 25 °C, IF = 0.5 A - Enables operation up to ~2 MHz switching frequency with minimal reverse recovery loss. |
| VF (max) | 1.45 V at IF = 15 A, Tj = 150 °C - Limits conduction loss to ≤21.8 W (P ≈ 1.05×IF(AV) + 0.053×IF²(RMS)) in high-temp operation. |
| Rth(j-c) | 1.5 °C/W - Allows direct heatsink mounting to sustain 15 A avg current with <22.5 °C temperature rise above case. |
| IR (max) | 400 µA at Tj = 150 °C, VR = VRRM - Ensures low leakage in high-temperature PFC hold-up and clamping functions. |
| Tj range | -40 °C to +175 °C - Validated for under-hood automotive use and industrial ambient conditions without derating. |
Pinout & Package
STTH15RQ06WY uses the DO-247 package: a single-ended, through-hole compatible, thermally enhanced plastic power package with isolated anode/cathode terminals, UL94 V0 epoxy, and 0.8 N·m recommended mounting torque. Dimensions: L = 19.85–20.15 mm, H = 15.45–15.75 mm, Dia. = 3.55–3.65 mm (mounting hole), mass = 4.40 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry point | Connected to high-side switch node (e.g., LLC half-bridge leg) for synchronous rectification or freewheeling path. |
| Cathode (K) | Forward current exit point | Connected to output rail or ground return; electrically isolated from tab-no metal tab connection in DO-247. |
| Mounting Hole (ØI) | Mechanical fastening only | Non-electrical; used for screw-mounting to heatsink; no electrical continuity to anode or cathode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability (HTOL, TC, UHAST, ESD) - enables use in ADAS power modules and on-board chargers. |
| Ultrafast soft recovery | trr ≤25 ns with S-factor >1.0 - reduces EMI generation and snubber stress in high-dV/dt LLC and PFC circuits. |
| High-temperature operation | Tj up to +175 °C with full VRRM guarantee - eliminates need for thermal derating in engine bay or enclosed industrial enclosures. |
| Low thermal resistance | Rth(j-c) = 1.5 °C/W - supports higher power density vs. TO-220AC (Rth(j-c) ≈ 2.0 °C/W) in same footprint area. |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant materials - meets automotive OEM environmental requirements and EU WEEE directives. |

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 |
|---|---|---|---|
| STTH15R06DJ | TO-220AC package, Rth(j-c) = 2.0 °C/W, same VRRM/IF(AV)/trr specs | Limited to lower-power (<800 W) or forced-air-cooled designs due to higher thermal resistance | Select when cost-sensitive industrial designs prioritize tube packaging and lower assembly complexity over thermal performance. |
| IXYS MUR1560CT | D²PAK package, dual common-cathode configuration, VF = 1.7 V (max @ 15 A/125 °C), trr = 35 ns | Requires PCB layout adaptation for dual-diode topology; higher VF increases conduction loss by ~18% | Choose only if dual-diode functionality is required and soft recovery is secondary to cost or inventory consolidation. |
Compared with STTH15R06DJ and IXYS MUR1560CT, STTH15RQ06WY offers superior thermal performance (1.5 vs. 2.0 °C/W), AEC-Q101 qualification for automotive use, and DO-247 mechanical ruggedness-making it optimal for high-reliability, high-power-density LLC and OBC applications where thermal headroom and EMI control are critical.

FAQ
What is the maximum allowable mounting torque for STTH15RQ06WY in DO-247 package?
The recommended mounting torque is 0.8 N·m, with a maximum allowable torque of 1.0 N·m. Exceeding this limit risks cracking the epoxy body or deforming the internal leadframe, potentially compromising thermal performance and long-term reliability. Torque must be applied using a calibrated tool with the screw centered on the mounting hole (ØI = 3.55–3.65 mm).
Does STTH15RQ06WY have a metal tab connected to either anode or cathode?
No. Unlike TO-220AC or D²PAK variants, the DO-247 package used in STTH15RQ06WY has fully insulated anode and cathode terminals-neither is electrically connected to the mounting hole or package body. This enables floating heatsink mounting and simplifies isolation design in high-voltage applications such as PFC and LLC secondary stages.
How does the soft recovery behavior impact EMI in high-frequency converters?
Soft recovery (S-factor >1.0) limits di/dt during turn-off, reducing high-frequency ringing and voltage overshoot across switching FETs. Measured data shows trr remains ≤70 ns even at dIF/dt = –200 A/µs, and IRM stays ≤8 A-directly lowering broadband EMI emissions and easing compliance with CISPR 25 Class 5 in automotive systems.
Can STTH15RQ06WY replace STTH15RQ06GY in D²PAK tape-and-reel format?
No-package substitution is not functionally interchangeable. STTH15RQ06WY (DO-247) has different thermal path, mounting method (screw vs. solder), and creepage geometry than STTH15RQ06GY (D²PAK). PCB layout, heatsink interface, and mechanical retention must be redesigned; electrical specs alone do not ensure drop-in compatibility.
