Circuit Element Recommendations

[kjnhu]

Could someone please recommend part values for the following components, or tell me if they do not exist:
1. differential op-amp that can source enough current to turn on a BJT and an LED, and also outputs a voltage near the +-5V inputs
2. a BJT that can withstand up to 2V across it
3. An LED with a breakdown voltage of greater than 5V
4. An PNP Transistor that can withstand very large voltages but turns on with below 5V difference.
5. The connectors that you see on a voltmeter to plug the testing leads into.
Thank you for any help you can be.
Kevin
