BZX58550-C3V6-QX

Single Zener Diodes Overview

The Nexperia BZX58550-C3V6-Q is a low-current voltage regulator diode from the BZX58550-Q series, designed for general regulation functions. It operates within a nominal working voltage range of 1.8 V to 51 V and features a ±5% tolerance series. The device is specified at a low test current of 50 μA, making it suitable for low bias and portable battery-powered applications. It is housed in an ultra-small SOD523 (SC-79) plastic surface-mounted package with dimensions of 1.2 mm x 0.8 mm x 0.6 mm. The component has a total power dissipation of up to 300 mW and is qualified according to AEC-Q101 standards.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'Q' indicates AEC-Q101 qualification for automotive suitability. Confirm the 'C' designation corresponds to the ±5% tolerance series as documented in the ordering information table. Ensure the package type matches the SOD523 outline provided in the datasheet before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when designing circuits requiring precise voltage regulation at very low currents, such as those powered by batteries. The ±5% tolerance offers a balance between cost and precision. Consider the thermal resistance characteristics if operating near the maximum junction temperature limits or in high-density PCB layouts where heat dissipation may be constrained.
