Product details
Overview
STTH5R06G-TR from STMicroelectronics is a 600 V, 5 A ultrafast high-voltage rectifier diode in D²PAK (TO-263) package, featuring 25 ns max reverse recovery time, 1.40 V typ forward voltage at 125 °C, and 175 °C max junction temperature - optimized for continuous-conduction-mode PFC boost stages and hard-switching flyback/freewheeling applications in industrial power supplies.
For engineers reviewing the STTH5R06G-TR datasheet, STTH5R06G-TR pinout, STTH5R06G-TR application, or STTH5R06G-TR equivalent, key selection criteria include reverse recovery time under dIF/dt stress, softness factor (0.35 min), thermal resistance (3.0 °C/W junction-to-case), and insulated package suitability for high-voltage isolation requirements.
Technical Context
This device employs ST's Turbo 2 600 V silicon technology to achieve ultrafast switching with low Qrr (110 nC) and low IRM (5.0–6.0 A), enabling reduced switching losses in high-frequency AC/DC converters. Its soft recovery behavior minimizes EMI generation during turn-off transitions.
The D²PAK package provides low thermal resistance (3.0 °C/W j-c) and supports surface-mount assembly while maintaining robust thermal performance up to 175 °C junction temperature - critical for compact, high-power-density designs where heatsinking area is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - withstands peak reverse voltages in 400 VAC input PFC circuits with safety margin |
| IF(AV) | 5 A at TC = 135 °C - defines continuous DC current capability with standard heatsink mounting |
| trr (max) | 25 ns at IF = 0.5 A, dIF/dt = −50 A/µs - enables operation up to ~1 MHz switching frequencies with low turn-off loss |
| VF (typ) | 1.40 V at Tj = 125 °C, IF = 5 A - determines conduction loss baseline for thermal design (P ≈ 1.164×IF(AV) + 0.128×IF²(RMS)) |
| Qrr | 110 nC - directly impacts switching loss and snubber sizing in hard-switched topologies |
| S factor | 0.35 min - ensures gradual current decay to suppress voltage overshoot and EMI in inductive load switching |
| Rth(j-c) | 3.0 °C/W - enables predictable junction temperature rise with measured case temperature in D²PAK layout |
Pinout & Package
D²PAK (TO-263) package: surface-mount, isolated tab (cathode-connected metal pad), 3-pin configuration with integrated thermal pad. Insulation not rated - unlike TO-220FPAC, D²PAK is non-insulated; electrical isolation must be achieved via PCB layout or external insulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input current terminal | Connected to switch node (e.g., MOSFET drain) in boost PFC; requires low-inductance routing |
| Cathode (Pin 2) | Output current terminal | Connected to output capacitor/bus; carries full load current and high di/dt transients |
| Tab / Thermal Pad (Pin 3) | Cathode connection & thermal path | Electrically tied to cathode; must be soldered to large copper pour for thermal management and EMI control |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 25 ns trr enables >500 kHz switching in PFC without excessive loss penalty |
| Low Qrr | 110 nC reduces turn-off energy loss and snubber dissipation in hard-switched converters |
| Soft recovery (S factor ≥0.35) | Minimizes voltage ringing and EMI during diode turn-off in inductive circuits |
| High Tj rating | 175 °C max junction temperature supports operation in thermally constrained enclosures |
| D²PAK thermal performance | 3.0 °C/W Rth(j-c) allows direct thermal modeling using PCB copper area as heatsink |
Applications
| Industrial AC/DC Power Supplies | Server & Telecom Rectification |
|---|---|
|
Use Scenario: Boost PFC stage in 1–3 kW industrial SMPS operating at 65–100 kHz with continuous conduction mode. IC Role / Device Role / Timing Role: Ultrafast freewheeling diode conducting during MOSFET off-time; handles high dIF/dt (>200 A/µs) during turn-on transition. Use Value: 25 ns trr and 0.35 S factor reduce voltage overshoot across switching FET, lowering stress and improving reliability vs. standard fast diodes. |
Use Scenario: Output rectification in phase-shifted full-bridge DC/DC converters for 48 V telecom systems. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement in high-efficiency isolated converters; operates with zero-voltage switching assist. Use Value: Low VF (1.40 V typ at 125 °C) cuts conduction loss by ~15% vs. legacy 1.7 V diodes, improving system efficiency at full load. |
| Motor Drive Inverter Freewheeling | Renewable Energy Inverters |
|
Use Scenario: Freewheeling path in IGBT-based 3-phase motor drives (10–50 HP) with 8–16 kHz PWM carrier. IC Role / Device Role / Timing Role: Clamps inductive kickback during IGBT turn-off; recovers before next PWM cycle begins. Use Value: 110 nC Qrr limits reverse recovery charge injection into DC bus, reducing bus capacitor stress and ripple current. |
Use Scenario: DC link clamping and auxiliary rectification in string inverters for solar PV systems (600–1000 V DC input). IC Role / Device Role / Timing Role: High-voltage boost diode in MPPT stage handling 600 V reverse bias and transient surges. Use Value: 600 V VRRM with 175 °C Tj rating ensures long-term reliability under desert ambient conditions and partial shading stress. |
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 |
|---|---|---|---|
| STTH8R06D | 8 A IF(AV), same 600 V VRRM, 30 ns trr, TO-220AC package | Through-hole mounting; higher current rating but larger footprint and no SMD compatibility | Select when board space permits through-hole assembly and higher average current (>5 A) is required |
| IXYS MUR560E | 5 A IF(AV), 600 V VRRM, 35 ns trr, TO-220AC, no soft recovery spec | Lacks documented softness factor; higher trr increases EMI risk in high-dIF/dt layouts | Acceptable only in lower-frequency (<300 kHz), low-EMI-sensitive designs with conservative layout |
Compared with STTH8R06D and IXYS MUR560E, STTH5R06G-TR delivers superior high-frequency performance due to its 25 ns trr and guaranteed soft recovery, while its D²PAK package enables automated assembly and better thermal integration than TO-220 alternatives - making it optimal for space-constrained, high-efficiency PFC modules.

FAQ
Is STTH5R06G-TR insulated or electrically isolated?
No, STTH5R06G-TR in D²PAK package is not electrically insulated - its metal tab is internally connected to the cathode. Unlike the TO-220FPAC variant (STTH5R06FP), it requires external PCB-level isolation if high-voltage barrier compliance is needed. The insulation voltage rating (2000 VRMS) applies only to the TO-220FPAC version.
What is the maximum recommended dIF/dt for reliable operation?
The datasheet specifies IRM and trr test conditions up to −200 A/µs (at Tj = 125 °C). For sustained reliability, ST recommends limiting dIF/dt to ≤150 A/µs in production designs - verified by measurement of VFR (forward recovery voltage) and Qrr stability across temperature and current stress profiles.
Can STTH5R06G-TR replace STTH5R06B in DPAK package?
No - although both share identical electrical specs, STTH5R06G-TR (D²PAK) has different thermal resistance (3.0 °C/W j-c vs. DPAK's 4.5 °C/W), larger footprint, and higher thermal mass. Substitution requires PCB layout revision and thermal validation; D²PAK offers better heat spreading but occupies more board area.
Does STTH5R06G-TR meet RoHS and REACH requirements?
Yes - STTH5R06G-TR is ECOPACK®2 compliant, meeting EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead-free terminations and halogen-free molding compound are confirmed in ST's official material declaration (DocID7976 Rev 12, Section 2).
