Jaycar 1N4737 Zener Diode – 7.5V, 1W

Your circuit calls for a 7.5V clamp and the local shop's shelf is empty. You don't need a 'close enough' part — you need the 1N4737. One watt of headroom, exact breakdown voltage, and it's here instead of sitting in some warehouse overseas. Solder it in, power up, done

• 7.5V Zener breakdown voltage for accurate clamping and regulation
• 1W continuous power rating for reliable sustained operation
• Part number 1N4737 — direct datasheet match, no cross-reference guesswork
• Jaycar-sourced component, stocked in Australia
