What are the key features of STPSC606G-TR?
- Silicon carbide (SiC) junction with zero reverse-recovery charge (Qrr = 0) eliminates switching losses at high frequencies, enabling 100+ kHz converter designs
- 600V reverse-voltage rating and 6A continuous forward current support boost PFC stages and flyback secondary rectification in AC/DC power supplies
- D2PAK-3 surface-mount package provides superior thermal performance with low RthJC, handling 27A non-repetitive surge current without package derating
What is STPSC606G-TR used for?
The STPSC606G-TR is used as a boost PFC output rectifier, flyback secondary diode, and freewheeling diode in switch-mode power supplies operating at 400V to 600V DC bus voltages. Its zero reverse-recovery characteristic makes it ideal for hard-switched and soft-switched topologies above 50 kHz where silicon Schottky diodes would cause unacceptable switching losses. Solar micro-inverters, EV on-board chargers, and industrial UPS systems benefit from the SiC diode's temperature-stable 1.7V forward drop across -40°C to +175°C.

Frequently Asked Questions
What advantage does the SiC Schottky junction of STPSC606G-TR provide over a conventional silicon rectifier at 100 kHz switching frequency?
STPSC606G-TR has zero reverse-recovery charge (Qrr = 0 nC) because SiC Schottky diodes have no minority carrier storage. A comparable 600V silicon ultra-fast rectifier typically has Qrr of 30–150 nC, causing a current spike at every switching transition. At 100 kHz, eliminating this spike reduces switching losses by 2–5W in a 300W PFC stage, improving converter efficiency by 1–2 percentage points and reducing MOSFET gate-drive stress.
For a 400W AC/DC boost PFC stage with a 390V DC output, is STPSC606G-TR's 600V / 6A rating adequate?
Yes. A 400W PFC output at 390V draws approximately 1A average diode current, well within the 6A continuous rating. Peak reverse voltage is typically 1.05 × 390V = 410V with ripple, providing over 190V of margin to the 600V blocking voltage. The 27A non-repetitive surge rating safely handles in-rush transients at startup when the output capacitor is discharged. The D2PAK-3 package dissipates up to 2W at a 1.7V forward drop without forced airflow.
How does STPSC606G-TR forward voltage behave over the -40°C to +175°C junction temperature range compared to silicon diodes?
STPSC606G-TR has a positive temperature coefficient of forward voltage, meaning VF increases slightly from approximately 1.4V at 25°C to 1.7V at 175°C (maximum). This contrasts with silicon PN rectifiers whose forward voltage decreases with temperature, which can cause thermal runaway in parallel diode configurations. The SiC Schottky's positive VF coefficient provides natural current sharing when two STPSC606G-TR diodes are placed in parallel, ensuring no single device hogs current at elevated temperatures.
Can STPSC606G-TR be used in a 48V-to-400V DC/DC flyback converter as the secondary-side rectifier, and what heat-sink approach is recommended?
STPSC606G-TR is a 600V device, adequate for rectifying a 400V output from a flyback converter where peak reverse voltage can reach 2× output = 800V — this exceeds the 600V rating, so a 1200V SiC diode is needed for 400V output flyback. For output voltages up to 250V the device is appropriate. Mount the D2PAK-3 on a copper pour area of at least 1 cm² to keep junction temperature below 150°C at 6A continuous, or use an external clip-on heat sink rated below 10°C/W.
