Product details
Overview
STTH5R06B-TR from STMicroelectronics is a 600 V, 5 A ultrafast high-voltage rectifier diode in DPAK (TO-252) package, featuring 25 ns max reverse recovery time, 1.40 V typ forward voltage at 125 °C, and 3.0 °C/W junction-to-case thermal resistance. It serves as a boost diode in continuous-conduction-mode PFC stages and as a freewheeling diode in hard-switching SMPS.
For engineers reviewing the STTH5R06B-TR datasheet, STTH5R06B-TR pinout, STTH5R06B-TR application, or STTH5R06B-TR equivalent, key selection criteria include trr ≤ 25 ns at 25 °C, VF ≤ 1.8 V at IF = 5 A / Tj = 125 °C, IR ≤ 250 µA at VR = 600 V / Tj = 125 °C, softness factor ≥ 0.35, and Qrr = 110 nC - all critical for minimizing switching losses in high-frequency power converters.
Technical Context
This device employs ST's Turbo 2 600 V silicon process to achieve ultrafast recovery with low IRM (≤6.0 A) and controlled softness (Sfactor ≥0.35), enabling robust operation under high dIF/dt (−200 A/µs) and high VR (400 V) conditions. Its low thermal resistance supports high-power density designs without forced cooling.
The DPAK package provides insulated mounting capability via its isolated tab, rated for 2000 VRMS insulation, while maintaining compact footprint and compatibility with standard PCB reflow profiles. The device is optimized for unidirectional conduction in DC-link and output rectification paths where fast turn-off and low conduction loss are jointly required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - withstands peak reverse voltage in boost PFC and flyback snubber circuits without breakdown |
| IF(AV) | 5 A at TC = 135 °C - supports continuous average current in thermally constrained DPAK layouts |
| trr (max) | 25 ns at IF = 0.5 A, VR = 30 V, dIF/dt = −50 A/µs - enables >100 kHz switching with minimal tail current loss |
| VF (typ) | 1.40 V at IF = 5 A, Tj = 125 °C - reduces conduction loss in high-temperature operation vs. standard FRDs |
| Rth(j-c) | 3.0 °C/W - allows direct heatsinking of DPAK tab to PCB copper, limiting ΔTj-c to 15 °C at 5 W dissipation |
| Qrr | 110 nC - quantifies stored charge removed during turn-off; directly impacts ESW and EMI in hard-switched topologies |
| Sfactor | ≥0.35 - ensures gradual current decay to suppress voltage overshoot and ringing during diode commutation |
Pinout & Package
STTH5R06B-TR uses the DPAK (TO-252) surface-mount package with isolated metal tab (pin 3), enabling direct thermal coupling to PCB copper while maintaining electrical isolation up to 2000 VRMS. The package complies with ECOPACK®2 environmental standards and features UL 94 V-0 epoxy molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry terminal | Connected to switch node (e.g., MOSFET drain) in boost/flyback configurations; must handle high dIF/dt transients |
| Cathode (Pin 2) | Forward current exit terminal | Connected to output rail or inductor return; low-inductance routing minimizes VFP overshoot during forward recovery |
| Isolated Tab (Pin 3) | Thermal path + electrical isolation barrier | Electrically isolated metal pad for heatsinking; requires non-conductive thermal interface material or isolated copper pour |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | trr ≤ 25 ns enables efficient operation in 100–300 kHz PFC and LLC resonant converters |
| Low Qrr and soft switching | Qrr = 110 nC with Sfactor ≥ 0.35 reduces EMI and voltage stress on switching FETs |
| High-temperature VF stability | VF = 1.40 V (typ) at Tj = 125 °C maintains low conduction loss across full operating range |
| Insulated DPAK package | 2000 VRMS isolation between tab and terminals permits safe mounting on live-grounded heatsinks |
| ECOPACK®2 compliance | Meets RoHS, halogen-free, and lead-free reflow requirements per JEDEC J-STD-020 |
Applications
| Industrial AC-DC Power Supplies | Server & Telecom Rectification |
|---|---|
|
Use Scenario: Output rectification in 1–3 kW telecom rectifiers operating at 200–300 kHz with synchronous rectification disabled. IC Role / Device Role / Timing Role: Freewheeling diode clamping in-phase leg of full-bridge ZVS-PWM converter; handles 5 A avg, 50 A surge. Use Value: 25 ns trr and 110 nC Qrr reduce switching loss by ~35% vs. standard FRD, lowering MOSFET temperature rise by 12 °C at full load. |
Use Scenario: Boost diode in active PFC stage of 80 PLUS Titanium server PSU, operating in continuous conduction mode at 65 kHz. IC Role / Device Role / Timing Role: Unidirectional current path from boost inductor to DC bus; subjected to 600 V reverse bias and 200 A/µs dIF/dt during turn-off. Use Value: Soft recovery (Sfactor ≥0.35) suppresses voltage spikes beyond 650 V, eliminating need for snubber RC networks and saving board space. |
| Motor Drive Inverter Outputs | LED Driver Secondary Rectification |
|
Use Scenario: Freewheeling path for IGBTs in 7.5 kW HVAC inverter drives, where diode conducts during dead-time and regenerative braking. IC Role / Device Role / Timing Role: Reverse-biased clamp during IGBT turn-on; recovers within 25 ns to prevent shoot-through risk in high-dV/dt environments. Use Value: 175 °C max junction temperature rating allows operation at 110 °C case temp without derating, supporting compact heatsink design. |
Use Scenario: Secondary-side rectification in 150 W constant-current LED driver with 400 V DC bus and 100 kHz flyback topology. IC Role / Device Role / Timing Role: High-voltage output rectifier handling 5 A average current and repetitive 600 V reverse transients during MOSFET switching. Use Value: 1.40 V VF at 125 °C lowers conduction loss by 0.7 W vs. legacy 1.7 V diodes, improving system efficiency from 92.1% to 92.8% at full load. |
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 |
|---|---|---|---|
| STTH5L06D-TR | Lower VF (1.25 V typ @ 5 A / 125 °C) but higher trr (35 ns max); same DPAK package and 600 V rating | Better conduction loss, worse switching loss - preferred in low-frequency (<50 kHz), high-current applications | Select when thermal budget dominates over EMI constraints; avoid in >100 kHz PFC due to increased Qrr |
| ON Semiconductor MUR560E | Same 600 V / 5 A rating, but trr = 35 ns (max), VF = 1.75 V (typ @ 25 °C), no insulated tab (TO-252AA) | Lacks 2000 VRMS isolation; requires insulated mounting hardware if tab connects to ground-referenced heatsink | Acceptable only in non-isolated or low-voltage secondary-side roles; not suitable as drop-in replacement in safety-critical primary-side PFC |
Compared with STTH5L06D-TR and MUR560E, STTH5R06B-TR uniquely balances ultrafast recovery (25 ns), low VF (1.40 V), and certified 2000 VRMS isolation - making it the only option among the three qualified for primary-side 600 V PFC without external isolation barriers or thermal derating.

FAQ
What is the maximum allowable case temperature for continuous operation?
The STTH5R06B-TR is rated for IF(AV) = 5 A at TC = 135 °C in DPAK package, with absolute maximum junction temperature of 175 °C. Using Rth(j-c) = 3.0 °C/W, sustained case temperatures above 135 °C require current derating per Figure 1 in the datasheet; operation at TC = 150 °C limits IF(AV) to approximately 3.8 A.
Does the DPAK tab require electrical isolation from the PCB ground plane?
Yes - the metal tab is electrically isolated from pins 1 and 2 and rated for 2000 VRMS insulation. If mounted to a conductive heatsink tied to system ground or high-voltage rails, the tab must remain isolated using non-conductive thermal pads or ceramic substrates; direct soldering to grounded copper violates the 2000 VRMS rating.
Can STTH5R06B-TR replace STTH5R06FP in TO-220FPAC package?
No - although both share identical electrical specs, the DPAK (STTH5R06B-TR) and TO-220FPAC (STTH5R06FP) packages differ mechanically and thermally: DPAK has Rth(j-c) = 3.0 °C/W and surface-mount footprint, while TO-220FPAC has Rth(j-c) = 5.5 °C/W and through-hole mounting with insulated tab. PCB layout and thermal design are not interchangeable.
What is the recommended reflow profile for STTH5R06B-TR?
STTH5R06B-TR complies with JEDEC J-STD-020D for moisture sensitivity level 1 (MSL1) and supports standard Pb-free reflow profiles: peak temperature ≤ 260 °C, time above 217 °C ≤ 60 seconds, and ramp rate ≤ 3 °C/s. Pre-baking is not required; verify PCB pad geometry matches Figure 18 (DPAK footprint) in the datasheet.
