Device Structure

Single Zener diode chip engineered for surface mounting. SOD-123 case provides compact footprint and good thermal performance. Designed for efficient heat dissipation in PCB layouts. Simple construction suitable for automated assembly.

Performance Characteristics

Offers stable breakdown voltage at 5.1 V with low leakage and tight tolerance. Maintains reliable operation up to 500mW power dissipation. Low forward voltage drop allows efficient power use. Can operate in wide temperature range without performance loss. Maximum impedance of 60 Ohms ensures consistent voltage regulation. Very low reverse leakage current reduces power waste.

Application Environments

Commonly used in consumer electronics, industrial controls, telecommunications, and automotive systems. Suitable for voltage reference, voltage protection, or simple regulation. Good choice for densely populated PCBs and portable devices. Operates well in harsh environments due to wide temperature range. Approved for applications requiring RoHS and REACH compliance.

Selection Guidelines

Choose this model when you need 5.1V regulation with moderate power handling. Consider SOD-123 packaging for space-limited designs. Make sure the 500mW max power is sufficient for your application. Check if ±6% voltage tolerance matches your circuit needs. Evaluate operating temperature needs for your application environment. For higher power or different voltage, select appropriate alternative models.

Usage Considerations

Ensure proper heat dissipation on PCB to avoid exceeding 500mW limit. Verify SOD-123 pad layout is compatible with your assembly process. Respect maximum reverse leakage and impedance ratings for reliable circuit operation. Store in recommended environment; low moisture sensitivity (MSL 1) allows easier handling in manufacturing. Confirm compliance requirements for RoHS and REACH.
