    Ok, so I need to power a 16V max Buzzer [datasheet: http://www.mouser.com/ds/2/252/MSR516NPR-24363.pdf]

    Now, I have to work with a 24 V source. I know I could use a divider, but I think the resistors I would be needing have to be either a lot of small ones (1/4W) or a few BIG (>1W) ones. What would you recommend?...

    And I'm having trouble modelling the buzzer in a simulator. In the datasheet, it says that it can draw a maximum of 12mA at 16V (I just assumed...), so is it ok to just model the whole buzzer as a resistor (16V/12mA = 1.3k) in series with a 12mA current source? If not, then what should it be?...

    The datasheet does list a maximum of 16 VDC and 12 mA for the buzzer, which is not a lot of power (less than 1/4 watt.) So a voltage divider might be possible, however (because it's what I know) I would lean toward a linear regulator, such as an LM78L15.

    Oh, and I don't know anything about simulation software.

    Your link failed, or I would look up the part and tell you how to feed it.
    I'm thinking 750 ohms 1/4 watt to a 15 volt, 1/4 watt zener diode.

    What I said will work. 24VDC, 750 ohms, then split to both the buzzer and a zener diode.
