A complete relay that is smaller than a Tyco RT series EMR Simple_solid_state_relay_Updated . This design uses a small double sided PCB and some SMD components. Here are the Gerber files SSLR. The recomended mosfets for this design are the PSMN4R3-100PS for supply rails of up to +-50 V absolute maximum, and for supply rails of up to +-75 V, the Fairchild FDB075N15A

Beautifully compact – A1, but the link (if that was intended) to the Gerbers is not yet active
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 ?
Yes that’s also an option as well.
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?
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 ?
what is the supply voltage of your amplifier?
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?
I will take a look over the weekend and come back to you.
Can you answer Geirge’s question? I am also confused about the symbol of TLP191. Also any drop in replacements for TLP device?
What are you confused about? Can you be more specific?
