## Description

Zener diodes are a handy little companion for all sorts of jobs. They are rated with a fixed breakdown (avalanche) voltage above which, unlike normal diodes, they'll allow reverse current flow.

But how could that be useful I hear you ask?

- Protecting micro-controller pins from excess voltage
- Providing a reference voltage
- Clamping signal voltages

We stock both 3V3 and 5V Zener diodes as these are the voltages most Raspberry Pi and Arduino projects will run at.

- Power: 1.3W
- Tolerance: ±5%

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=COM2601:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/COM2601:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; `search.md?q=` also works)
