If you're looking to turn your $30,000 in savings into a regular passive income stream, you best not be tucking that cash under your mattress!

Now, some banks are offering term deposit rates of up to 5.0% at the moment. And putting your money in the bank does come with less risk than investing in ASX shares. However, those bank deposit rates will eventually come down once the Reserve Bank of Australia is confident inflation is back in hand and begins easing, which is likely next year.

On the other hand, the yields offered by many S&P/ASX 200 Index (ASX: XJO) dividend stocks could well improve amid a falling official Australian cash rate.

I also like ASX 200 dividend stocks for the franking credits many of them provide. This gives you credit for the corporate taxes they've already paid on their profits before they distribute those dividends to eligible shareholders. It should enable me to hold onto more of that passive income when it's time to pay the ATO its annual pound of flesh.

Two quick points

Before turning to how I'd aim to achieve $2,070 in annual passive income from $30,000 in savings, two quick points.

First, we'll look at three quality ASX 200 dividend stocks below, each operating in different sectors. However, a properly diversified income portfolio should contain more, say, 10 stocks. That will help reduce the risk of your entire portfolio taking an outsized hit if any single company or sector runs into a rough patch.

Second, keep in mind that the yields you generally see quoted are trailing yields. Future yields may be higher or lower depending on a range of company-specific and macroeconomic factors.

Alrighty then… let's dive in.

Three ASX 200 dividend stocks for bank-busting passive income

The first ASX 200 stock I'd buy for passive income is intellectual property (IP) services company IPH Ltd (ASX: IPH).

IPH has been increasing its dividend payouts every year for more than a decade now. Over the past year, the company paid 35 cents a share in partly franked dividends. At yesterday's closing price of $5.36, IPH shares trade on a partly franked trailing yield of 6.5%.

I'd also buy ASX 200 energy giant Woodside Energy Group Ltd (ASX: WDS).

Woodside's dividends have fallen alongside the pullback in oil and gas prices. However, it remains a reliable income stock, and its dividends should again climb higher when global energy prices pick back up.

As for the past year, Woodside paid a total of $1.937 a share in fully franked dividends. At yesterday's closing price of $23.49, Woodside shares trade on a fully franked trailing yield of 8.2%.

This brings us to our third passive income stock, agribusiness and processing company, Graincorp Ltd (ASX: GNC).

Graincorp paid out a total of 54 cents a share in fully franked dividends over the past 12 months. At yesterday's closing price of $8.94, Graincorp shares trade on a fully franked trailing yield of 6.0%.

If I invested my $30,000 evenly across these three ASX 200 dividend stocks, I could expect to earn an average yield of 6.9%.

Or a tidy $2,070 a year in passive income.
