    Beautifully compact – A1, but the link (if that was intended) to the Gerbers is not yet active

    • Bonsai says:

      Sorry the link in the Doc is not active. It will be a link to the Gerber file in the actual post. I will update it later today.

    What about the avago Dual Channel Photovoltaic MOSFET Driver ASSR-V622-002E ?

    Hi I am looking for a stereo protection board with supplies of 35v and 70 v. Do you have any PCB implementation with SSR with discreet devices for start delay, short circuit and DC protect?

    • Bonsai says:

      Prasi, I do not have anything specifically for the voltages you are mentioning (35 and 70 Volts). However, the PSU +Protect circuit (see the nx-Amplifier write-up) could be used with some modification of the values. I will take a look at it in the next few days and make some proposals.

      Can you tell me why you want 35V and 70V?

    Hi Andrew, I need an ssr for a 500 watt/channel into 8 ohm amp, which needs mosfets for up to 100 – 150 volts to be safe and 10 -15 amps.

    Do u know such fets which have audio freq linearity ?

    Also, do u sell your products in kit form ?

    Hello Bonsai,

    I have a question regarding U5, the TLP191. The data sheet shows the pinout as anode pin 1, cathode pin3, cathode pin 4, anode pin6. how doe this pinout match up to you’re schematic?

    regards,
    George

    Thanks

    hi Bonsai,
    Can you answer Geirge’s question? I am also confused about the symbol of TLP191. Also any drop in replacements for TLP device?

    Hi Andrew

    TLP191 is apparently EOL. Can Vishay VOM1271 be used as an alternative or do you have a better choice?

    Hi Andrew,

    Is FDP075N15A-F102 still the best choice for amplifiers with psu +/- 60-70VDC? I was looking at theToshiba TK4R9E15Q5 with 4,9mohm RDSon, but the gatecharge is 96nQ compared to the Onsemi device.
    I got the LTspice model for the Toshiba device and can see switching times higher than other devices with app. 70nQ gatecharge. (Don’t have the Spicemodel for the Onsemi device)

    Would you still use FDP075N15A?

    BR

    Hi Andrew,

    Just to be sure. You would use the FDP075N15A?

    BR/Claus
