Flyback converters are state of the art when it comes to low power auxiliary supplies in white goods. An important part of that converter is the so called snubber or clamping circuit, built from a Fast or Ultrafast Recovery Rectifier in series to a Transient Voltage Suppressor (TVS) Diode. Typically used is the US1J, a 1 A / 600 V / 75 ns rectifier in DO-214AC/SMA along with the P6SMBJ170A, a 600 W Suppressor with 170 V of working and 275 V of clamping voltage in DO-214AA/SMB. 

When space is restricted - which is often the case at white goods - it would be desirable to get also the TVS in an SMA package. But the P4SMA(J) family offers only 400 W of peak pulse power, which in many cases might be too low. The new P6SMA(J) family by Diotec closes this gap by offering 500 W for the lower working voltage range up to 204 V, and even 600 W for higher voltages. The US1J is available in volumes from stock. The P6SMA240A and P6SMA480A are available in sample quantities, while the P6SMAJ170A and P6SMA440A will follow in a short time.
