Product details
Overview
STTH15L06G from STMicroelectronics is a 600 V, 15 A ultrafast high-voltage rectifier diode in D²PAK package, optimized for discontinuous-mode PFC boost stages and secondary-side rectification in switching power supplies. It delivers typ. 0.95 V forward voltage at 15 A and 150 °C, 55 ns max reverse recovery time, and 1.7 °C/W junction-to-case thermal resistance.
For engineers reviewing the STTH15L06G datasheet, STTH15L06G pinout, STTH15L06G application, or STTH15L06G equivalent, key selection criteria include reverse recovery performance under high dIF/dt (≤100 A/µs), softness factor stability up to 125 °C, and thermal impedance behavior in pulsed conduction.
Technical Context
The STTH15L06G employs ST's Turbo 2 silicon technology to achieve ultrafast switching with low Qrr (typ. 800 nC at 125 °C) and controlled soft recovery (S factor ≥0.8). Its design targets high-frequency PFC where low trr and minimal IRM reduce EMI and switching losses.
It operates with rated IF(AV) = 15 A at Tc = 120 °C in D²PAK, supports surge currents up to 200 A (10 ms sine), and maintains stable VF and trr across -65 to +175 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive reverse voltage up to 600 V in bridge or boost configurations without breakdown. |
| IF(AV) | 15 A at Tc = 120 °C - Sustains average forward current of 15 A with heatsink at 120 °C case temperature. |
| VF (typ) | 0.95 V at IF = 15 A, Tj = 150 °C - Low conduction loss enables high-efficiency rectification in thermally constrained designs. |
| trr (max) | 55 ns at IF = 0.5 A, Irr = 0.25 A - Ultrafast recovery minimizes switching loss and ringing in >100 kHz PFC stages. |
| Rth(j-c) | 1.7 °C/W - Enables efficient heat transfer from junction to heatsink in D²PAK footprint with copper pad. |
| IRM (max) | 12 A at dIF/dt = 100 A/µs, VR = 400 V - Low peak reverse recovery current reduces stress on gate drivers and snubbers. |
| Tj max | 175 °C - Supports operation in high-ambient industrial environments with derated conduction capability. |
Pinout & Package
D²PAK (TO-263) surface-mount package with isolated tab (pin 1 = anode, pin 2 = cathode, tab = cathode). Designed for high-current PCB mounting with thermal pad soldered to large copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Forward current entry | Connected to AC input or switch node in boost PFC; must withstand 200 A surge transients. |
| Pin 2 (Cathode) | Forward current exit / reverse blocking terminal | Drives output capacitor or DC bus; electrically tied to exposed metal tab for thermal and electrical continuity. |
| Tab (Cathode) | Primary thermal path & cathode connection | Soldered to ≥10 cm² copper pour for Rth(j-a) ≤ 30 °C/W; requires isolation from chassis if floating ground topology used. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery (trr ≤ 55 ns) | Enables >200 kHz PFC operation while limiting switching loss and EMI generation in compact converters. |
| Low Qrr (800 nC typ. at 125 °C) | Reduces energy dissipated during turn-off, lowering MOSFET gate driver stress and improving system efficiency. |
| Soft recovery (S factor ≥ 0.8) | Minimizes voltage overshoot and oscillation during diode commutation, easing EMI filter design. |
| High Tj rating (175 °C) | Permits operation in sealed enclosures or high-ambient industrial settings without forced air cooling. |
| Low Rth(j-c) (1.7 °C/W) | Allows direct thermal coupling to PCB copper, eliminating need for mechanical heatsinks in mid-power applications. |
Applications
| Server PSU PFC Stage | Industrial SMPS Output Rectification |
|---|---|
Use Scenario: Discontinuous conduction mode (DCM) boost PFC in 1–3 kW server power supplies operating at 100–200 kHz. IC Role / Device Role / Timing Role: High-voltage boost diode conducting only during switch off-time; defines PFC stage efficiency and thermal budget. Use Value: 55 ns trr and soft recovery reduce MOSFET turn-on loss and snubber size, enabling smaller magnetics and higher power density. | Use Scenario: Secondary-side rectification in 48 V/20 A industrial DC-DC modules with natural convection cooling. IC Role / Device Role / Timing Role: Main output rectifier handling continuous 15 A DC load with transient surges up to 200 A. Use Value: 1.7 °C/W Rth(j-c) and 175 °C Tj allow full-rated current without external heatsink when mounted on 12 cm² copper. |
| Telecom Rectifier Modules | EV Charger Auxiliary Power Supply |
Use Scenario: Input rectification in telecom -48 V DC distribution systems with hot-swap and redundancy requirements. IC Role / Device Role / Timing Role: Primary AC/DC interface diode in redundant 3 kW front-end modules; handles line surges and reverse polarity events. Use Value: 200 A IFSM and 600 V VRRM ensure robustness against lightning-induced transients and backfeed conditions. | Use Scenario: Auxiliary 12 V/5 A supply in liquid-cooled EV on-board chargers, powered from main DC link. IC Role / Device Role / Timing Role: High-reliability flyback or forward rectifier operating continuously at 125 °C ambient with 100% duty cycle. Use Value: Stable VF and trr over temperature enable predictable conduction loss and thermal management across vehicle operating range. |
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 MUR1560CT | 600 V, 15 A dual common-cathode TO-220; trr = 60 ns (max), VF = 1.7 V (typ. at 25 °C) | Requires dual-diode layout; higher VF increases conduction loss at high Tj | Select when dual configuration simplifies board layout and thermal design permits higher VF penalty. |
| Vishay VS-15EWH06FN-M3 | 600 V, 15 A D²PAK; trr = 50 ns (max), VF = 0.92 V (typ. at 150 °C), Rth(j-c) = 1.8 °C/W | Near-identical thermal and dynamic specs; slightly lower trr but marginally higher thermal resistance | Prefer for lowest possible trr in critical EMI-sensitive designs where 0.1 °C/W difference is negligible. |
Compared with MUR1560CT and VS-15EWH06FN-M3, the STTH15L06G offers best-in-class softness factor (>0.8) and superior trr stability over temperature-critical for consistent PFC efficiency across wide ambient ranges.

FAQ
What is the maximum allowable case temperature for continuous 15 A operation?
The STTH15L06G supports IF(AV) = 15 A at Tc = 120 °C in D²PAK package per Table 2. Exceeding this requires derating; at Tc = 100 °C, it sustains ~17.5 A, and at Tc = 80 °C, ~20 A. Thermal design must ensure tab temperature remains within limit using verified PCB copper area and layout.
Does STTH15L06G have a built-in anti-parallel diode or integrated gate resistor?
No. The STTH15L06G is a single ultrafast silicon rectifier diode with no integrated components. It contains no anti-parallel diode, gate resistor, or protection circuitry. External snubbers or clamps must be added per application requirements, especially in hard-switched topologies.
How does its softness factor affect EMI in PFC circuits?
The STTH15L06G maintains S factor ≥0.8 across temperature and dIF/dt (Fig. 8), meaning reverse recovery current decays smoothly without abrupt zero-crossing. This suppresses high-frequency ringing and dv/dt spikes, directly reducing conducted EMI and easing compliance with EN 55022 Class B limits without oversized filters.
Can STTH15L06G replace STTH1506D in existing TO-220AC designs?
No direct drop-in replacement: STTH15L06G uses D²PAK (surface-mount) while STTH1506D uses TO-220AC (through-hole). Mechanical, thermal, and layout changes are required. Electrically, both share identical VRRM, IF(AV), and trr specs, but D²PAK offers lower Rth(j-c) (1.7 vs. 1.7 °C/W same value, but different test condition) and higher IFSM (200 A vs. 150 A).
