Product details
Overview
STTH15L06G-TR from STMicroelectronics is a 600 V, 15 A ultrafast high-voltage rectifier diode in D²PAK package, optimized for discontinuous-mode PFC boost stages and switching power supply output rectification. It delivers typ. 0.95 V forward voltage at 15 A/150 °C, 55 ns reverse recovery time, and 1.7 °C/W junction-to-case thermal resistance.
For engineers reviewing the STTH15L06G-TR datasheet, STTH15L06G-TR pinout, STTH15L06G-TR application, or STTH15L06G-TR equivalent, key selection criteria include ultrafast trr performance under high dIF/dt, low conduction loss at elevated Tj, soft recovery behavior (S factor >0.8), and thermal management capability in high-density industrial SMPS designs.
Technical Context
The STTH15L06G-TR employs ST's Turbo 2 silicon process to achieve ultrafast switching with controlled softness (S factor >0.8 at 125 °C), minimizing EMI and voltage overshoot during turn-off. Its low Qrr (≤1600 nC) and low IRM (≤12 A) reduce snubber stress in high-frequency PFC circuits.
Designed for operation up to 175 °C junction temperature, it supports high ambient industrial environments. The D²PAK package enables efficient heat transfer via PCB copper area, with Rth(j-a) dropping to ~25 °C/W on 35 µm FR4 with 30 cm² copper pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive reverse voltage in 400 V DC-link PFC and SMPS output stages without breakdown. |
| IF(AV) | 15 A @ Tc = 120 °C - Sustains average forward current in thermally constrained D²PAK-mount applications. |
| VF (typ) | 0.95 V @ 15 A, 150 °C - Reduces conduction loss to ≤1.5 W at rated current, critical for efficiency in high-power converters. |
| trr (max) | 55 ns @ 25 °C - Enables reliable operation at switching frequencies up to 200 kHz in discontinuous PFC. |
| Rth(j-c) | 1.7 °C/W - Allows direct thermal path from die to heatsink via soldered tab, supporting compact thermal design. |
| IRM (max) | 12 A @ 125 °C - Limits peak reverse recovery current, reducing gate drive stress on companion MOSFETs. |
| Qrr (max) | 1600 nC @ 125 °C - Low stored charge minimizes energy dissipation during diode commutation. |
Pinout & Package
D²PAK (TO-263) surface-mount package with isolated tab (pin 1 = anode, pin 2 = cathode, tab = cathode). Designed for high-current PCB trace routing and thermal coupling to internal copper planes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input terminal for forward conduction | Connected to AC or switched node; must withstand full reverse voltage when off. |
| Cathode (Pin 2) | Output terminal for forward conduction | Connected to output rail or PFC choke; carries full load current and serves as thermal path. |
| Tab (Cathode) | Thermal and electrical cathode connection | Must be soldered to ≥10 cm² copper pour for Rth(j-a) <30 °C/W; electrically tied to Pin 2. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| STTH16L06D | TO-220AC package; IF(AV) = 16 A @ Tc = 140 °C; Rth(j-c) = 1.5 °C/W; same VRRM/trr/VF specs. | Requires mechanical mounting and heatsink; better for lower-volume, serviceable designs. | Select when board space allows through-hole assembly and higher thermal margin is needed. |
| IXYS MUR1560CT | D²PAK dual common-cathode; VF = 1.7 V @ 15 A/25 °C; trr = 60 ns; no soft recovery data published. | Higher conduction loss; less predictable EMI behavior in fast-switching PFC. | Consider only if dual-diode configuration is required and softness is not critical. |
Compared with STTH16L06D, the STTH15L06G-TR trades 1 A IF(AV) margin for surface-mount compatibility and reduced assembly cost; versus MUR1560CT, it offers superior softness and 0.75 V lower VF at 150 °C-directly improving PFC efficiency by ~0.8% at full load.

FAQ
What is the maximum recommended PCB copper area for optimal thermal performance of STTH15L06G-TR?
The datasheet specifies Rth(j-a) drops to ~25 °C/W with 30 cm² of 35 µm FR4 copper under the D²PAK tab. For production designs, a minimum of 15 cm² is recommended to maintain Tj <150 °C at 15 A continuous. Thermal vias (≥8×0.3 mm) beneath the tab further reduce Rth(j-a) by 15–20%.
Does STTH15L06G-TR support synchronous rectification replacement?
No-STTH15L06G-TR is a unidirectional silicon PN junction diode and cannot be replaced by a synchronous rectifier without circuit redesign. Its ultrafast trr and soft recovery are optimized for hard-switched topologies; synchronous FETs require gate drive timing control and introduce shoot-through risk if substituted directly.
How does the softness factor (S) impact EMI in PFC applications?
A softness factor >0.8 ensures gradual current decay during reverse recovery, limiting di/dt-induced voltage spikes across parasitic inductances. In 200 kHz DCM PFC, this reduces conducted EMI above 30 MHz by 8–10 dB compared to standard ultrafast diodes with S <0.5, easing EMC filter design.
Is STTH15L06G-TR qualified for automotive underhood use?
No-STTH15L06G-TR is not AEC-Q101 qualified and is not recommended for automotive underhood applications. Its datasheet explicitly excludes automotive environments, and no qualification test reports (e.g., HTOL, TC, HAST) are published for this part. Industrial-grade thermal and reliability validation applies only to non-automotive use cases.
