I'm after a very small, but not surface mount rectifier: low voltage, low current ( max 10v 100mA) . Has to be physically smaller than 1N4000 series. 1N4148 size would be ideal. For a replacement in a guitar pedal used as reverse voltage protection.

Thank you in advance.

@gazpacholulu 1N4148 Small Signal Switching Diode - 10, 50, 100pcs - UK Seller | eBay

Thanks Peter but I have literally hundreds of 914's and 4148's. I was specifically a rectifier for preventing circuit board damage if the 9v power supply is reversed. I would hazard a guess that 1N4148's might go pop with reverse voltage being applied with no other protection in the circuit but I could always try one and flip the battery.
