MMBZ5238C-G3-08

Single Zener Diodes Overview

The MMBZ5238C-G3-08 is a single Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features an 8.7 V nominal Zener voltage with a ±2% tolerance and a maximum power dissipation of 500 mW. The device utilizes an SOD-123 surface-mount package, measuring 2.85 mm in length, 1.7 mm in width, and 1.25 mm in height. Electrical characteristics include a maximum reverse leakage current of 3 µA at 6.5 V and a Zener impedance of 8 Ohms at a test current of 20 mA. It operates within a temperature range of -55°C to +150°C.

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized distribution channels due to potential counterfeiting risks. Confirm RoHS compliance status via official datasheets before integration. Ensure storage conditions maintain moisture sensitivity level integrity. Validate package dimensions against PCB footprint requirements during design phase. Check for specific ordering suffix variations that may affect packaging or testing criteria.

Single Zener Diodes Selection Notes

Select this component when high precision is required alongside space constraints. The SOD-123 package offers a balance between thermal performance and board area efficiency. Consider the 8.7 V breakdown point relative to system supply rails. Evaluate the low leakage current specification for high-impedance node stability. Compare thermal resistance values if operating near maximum power limits.
