Product details
Overview
STPSC6H065B-TR from STMicroelectronics is a 6 A, 650 V silicon carbide (SiC) Schottky power diode in DPAK package, designed for high-efficiency PFC and hard-switching DC-DC converters. It delivers zero reverse recovery charge, temperature-independent switching, and 60 A non-repetitive surge capability at 10 ms, enabling robust operation in industrial switch-mode power supplies.
For engineers reviewing the STPSC6H065B-TR datasheet, STPSC6H065B-TR pinout, STPSC6H065B-TR application, or STPSC6H065B-TR equivalent, key selection criteria include forward voltage drop at 150 °C (1.98–2.50 V), junction-to-case thermal resistance (1.6–2.4 °C/W), reverse leakage current at 150 °C (50–250 µA), and total capacitive charge (18 nC at 400 V).
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-frequency, high-temperature power conversion stages. Its wide bandgap enables a 650 V blocking rating with no minority carrier storage, eliminating reverse recovery losses and associated EMI.
The device operates up to 175 °C junction temperature and exhibits stable dynamic characteristics across temperature-capacitance (300 pF at 0 V), Qcj (18 nC at 400 V), and VF drift are all specified over -40 to +175 °C, supporting reliable design in thermally constrained PFC boost stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Enables use in universal-input PFC stages with 400 V DC bus and 20% margin. |
| IF(AV) | 6 A at Tc = 135 °C - Sustains continuous conduction mode (CCM) PFC output current without derating. |
| VF @ 6 A, 150 °C | 1.98–2.50 V - Low conduction loss improves efficiency vs. Si FRD; enables <1.5 W conduction loss at 6 A RMS. |
| IFSM (10 ms) | 60 A - Withstands inrush and overload transients in AC-DC front ends without failure. |
| Rth(j-c) | 1.6–2.4 °C/W - Allows direct mounting on heatsink; supports >80 W dissipation at ΔT = 100 °C. |
| Cj @ 0 V | 300 pF - Low capacitance minimizes turn-off displacement current and EMI in MHz-range LLC resonant converters. |
| Qcj @ 400 V | 18 nC - Predictable capacitive charge simplifies snubber design and reduces switching loss sensitivity to layout parasitics. |
Pinout & Package
DPAK (TO-252) surface-mount package with insulated epoxy (UL94 V0), 0.32 g mass, and recommended footprint per DS9064 Figure 12. Thermal pad exposed on underside for direct PCB copper thermal coupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | Power input terminal / thermal path | Exposed metal tab serves as both anode connection and primary thermal interface to PCB copper pour. |
| Cathode (Pin 2) | Power output terminal | Single Gull-wing lead carries full load current; requires ≥0.5 mm trace width for 6 A continuous routing. |
| NC (Pin 1) | No connection | Unused lead-must remain unconnected and not soldered to avoid mechanical stress or unintended capacitance. |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery charge | Eliminates turn-off tail current and associated switching loss-critical for >100 kHz PFC designs. |
| Temperature-independent switching | Qcj, Cj, and VF variation bounded across -40 to +175 °C-enables stable loop response in wide-temp environments. |
| High forward surge capability | 60 A IFSM at 10 ms allows direct integration into unbuffered rectifier outputs without external fusing. |
| Insulated DPAK package | UL94 V0 epoxy and isolation between tab and leads enable safe mounting on non-isolated heatsinks in Class I systems. |
| ECOPACK®2 compliance | Meets RoHS, halogen-free, and REACH requirements-supports green product certification for industrial OEMs. |
Applications
| Industrial PFC Boost Stage | Server PSU LLC Resonant Rectification |
|---|---|
Use Scenario: 3.3 kW active PFC front-end operating at 70 kHz with 400 V DC bus and 12 A peak line current. IC Role / Device Role / Timing Role: Unidirectional high-voltage output rectifier in continuous conduction mode (CCM) boost converter. Use Value: Zero Qrr eliminates reverse recovery loss (≈1.2 W saved vs. Si FRD), reducing heatsink size by 35% at same ambient. | Use Scenario: Secondary-side synchronous rectification in 1.5 MHz LLC DC-DC converter powering 48 V server racks. IC Role / Device Role / Timing Role: High-frequency freewheeling diode clamping resonant tank voltage during dead-time intervals. Use Value: 300 pF Cj limits displacement current to <12 mA at 1.5 MHz-reducing EMI filter component count by two X2 capacitors. |
| Telecom 48 V Intermediate Bus Converter | Solar Inverter DC Link Clamp |
Use Scenario: 1.2 kW isolated DC-DC module converting 380 V DC to 48 V for telecom base station power distribution. IC Role / Device Role / Timing Role: Output rectifier in phase-shifted full-bridge topology with ZVS operation. Use Value: 175 °C max junction temperature allows operation at 85 °C ambient without forced air-enabling fanless enclosure design. | Use Scenario: Bidirectional clamp diode protecting IGBTs in 1000 V DC link of string inverters during grid fault conditions. IC Role / Device Role / Timing Role: Transient overvoltage clamp during DC link voltage overshoot events (>750 V). Use Value: 650 V VRRM with 20% margin ensures reliable clamping at 700 V transients-preventing IGBT avalanche failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D06065E-TR | Same 6 A / 650 V rating; TO-252 package; 1.75 V VF @ 25 °C but higher 2.65 V @ 150 °C. | Higher VF drift with temperature increases conduction loss by ~18% at full load and 100 °C case temp. | Select when lower room-temp VF prioritized over thermal stability; verify thermal design margin at elevated ambient. |
| SS16HE3/5AT | 6 A / 600 V Si Schottky; 0.75 V VF @ 25 °C but exhibits Qrr > 35 nC and Tj(max) = 150 °C. | Reverse recovery causes 3× higher switching loss and EMI in >50 kHz PFC; unsuitable above 85 °C ambient. | Only acceptable for low-frequency (<30 kHz), low-power (<500 W), or cost-sensitive consumer-grade designs. |
Compared with C3D06065E-TR, STPSC6H065B-TR offers superior thermal stability of VF and lower Qcj; versus SS16HE3/5AT, it delivers true zero-Qrr operation and 25 °C higher junction rating-enabling smaller heatsinks and higher reliability in industrial PFC.

FAQ
What is the maximum allowable case temperature for continuous 6 A operation?
The datasheet specifies IF(AV) = 6 A at Tc = 135 °C for DPAK package. Exceeding this temperature requires linear derating per Figure 4; at 150 °C case, average current must be reduced to ≈4.3 A to maintain safe junction temperature below 175 °C.
Does STPSC6H065B-TR require a gate resistor or driver circuit?
No-this is a passive Schottky diode with no gate terminal. It conducts when anode voltage exceeds cathode by >1.5 V and blocks when reverse biased. No external drive, gate resistor, or bias network is needed, unlike MOSFETs or IGBTs.
Can this diode replace a standard silicon fast recovery diode in an existing PFC board?
Yes-pin-compatible replacement in DPAK footprint, but thermal and layout validation is required: SiC's lower VF reduces conduction loss, yet its faster switching demands tighter control of stray inductance and snubber placement to manage dV/dt-induced ringing.
What is the insulation voltage rating of the DPAK package?
The DPAK package itself is not rated for high-voltage isolation-the "insulated" designation applies only to the TO-220AC Ins variant (2500 VRMS). The STPSC6H065B-TR DPAK has standard UL94 V0 epoxy but no reinforced creepage/clearance rating; system-level isolation must be maintained via PCB layout and spacing.
