Summary of Piezo buzzer Sonitron SMA-13LV deploys maximum from a minimum
Sonitron's SMA-13LV is a low-voltage piezo buzzer in the SMA series, suited for general and industrial use. SMA buzzers offer varied loudness (75–98 dB), THT/SMT packages, stable or intermittent signals, and sizes from 13–30 mm. They operate over wide voltage ranges (e.g., 1.5–15V), with higher voltage giving greater loudness and lower voltage extending lifetime. Related lines: SMAT transducers (no driver) and rugged SAP series for harsh environments.
Parts used in the SMA-13LV Project:
- Sonitron SMA-13LV piezo buzzer
- Supply voltage source (e.g., 1.5–15 V)
- PCB mounting option: THT or SMT footprint
- Optional external driver (if using SMAT transducer instead)
- Industrial-grade enclosure or mounting hardware (for harsh environments)

Belgian company Sonitron and its top-level products ar probably familiar to you from our articles and from our offer in this segment. We continue in increasing of standard stock types and this time we have here an extraordinary interesting type – SMA-13LV, interesting mainly for low-voltage applications. Series of buzzers marked as “SMA” is known by its variousness, as we find here types with loudness of 75-98 dB, THT and SMT versions, and versions with a stable, as well as intermittent signal. Various sizes from 13 to 30 mm with a pitch of 7.5 to 20.32 mm enable to select the right type for a given application. In general, bigger types provide a more loud signal, but it depends on a concrete type. This series is suitable for general use – everywhere, where a reliable buzzer is necessary, including industrial conditions.
For a succesful use, it´s only necessary to connect a suitable supply voltage – usually in extremely wide range (for example 1.5-15V). Usually, on the upper end of a supply voltage range we get the highest loudness and at lower voltages we receive a higher lifetime.
Very similar is also the SMAT series (transducers), which in contrast to the SMA series doesn´t contain a driver, that´s why it needs extenal electronics.
For really tough conditions, the Sonitron SAP. series is suitable. These are buzzers for various usage in traffic, for example as a reverse movement indicator (danger of close approximation). They excel in extreme rigidity, what make them widely used even in avionics, miltary and trucks. SAP series has a specific usage, that´s why we keep these types as items upon request.
Another novelties in our standard stock offer can be found below this article. Detailed information can be found in datasheets at particular types and in the new Sonitron 2014 catalogue.

- What is the operating voltage range for SMA series buzzers?
The article states an extremely wide range, for example 1.5–15 V. - Does higher supply voltage affect loudness?
Yes, the article says the upper end of the supply voltage range usually gives the highest loudness. - Does lower supply voltage affect buzzer lifetime?
Yes, the article notes lower voltages generally provide a higher lifetime. - Are there SMT and THT versions available?
Yes, the SMA series includes both THT and SMT versions. - What loudness range is available in the SMA series?
The series offers types with loudness from 75 to 98 dB. - What is the difference between SMA and SMAT series?
SMAT transducers lack a driver and therefore need external electronics, unlike SMA which contains a driver. - Which Sonitron series is suitable for very tough conditions?
The SAP series is designed for very tough conditions and specific uses like traffic and avionics. - What sizes are available in the SMA series?
Sizes range from 13 to 30 mm with pitches from 7.5 to 20.32 mm.
