Overview
The SZMMSZ13T1G is a single Zener diode manufactured by onsemi, designed for surface-mount applications in the SOD-123 package. It features a nominal Zener voltage of 13V with a tolerance of ±5%. The device supports a maximum power dissipation of 500mW and operates within a junction temperature range of -55°C to +150°C. Key electrical parameters include a test current of 9.5mA, a maximum Zener impedance of 13Ω, and a maximum reverse leakage current of 500nA.
Feature Summary
- Provides stable voltage regulation at a nominal 13V level
- Designed for compact surface-mount PCB layouts
- Capable of handling up to 500mW power dissipation
Applications
- Voltage reference circuits
- Over-voltage protection
- Clipping and clamping applications
Procurement Notes
Verify the complete part number includes the 'G' suffix (SZMMSZ13T1G) to ensure compliance with RoHS standards and lead-free manufacturing requirements. Confirm that the SOD-123 package dimensions align with your PCB footprint design. Ensure the 500mW power rating is sufficient for your specific thermal environment and duty cycle requirements.
Selection Notes
Select this component when a precise 13V reference is required in a small form factor. The ±5% tolerance suits general-purpose regulation tasks. Consider the 500nA leakage current limit for low-power standby modes. The wide operating temperature range makes it suitable for industrial environments where thermal stability is critical for consistent voltage performance.
Part Context
This part belongs to onsemi's standard Zener diode portfolio, utilizing the SOD-123 surface-mount package. It is distinct from automotive-grade variants which typically carry different prefixes or suffixes. The component serves as a fundamental discrete semiconductor device for basic voltage control functions in consumer and industrial electronics.
Replacement Considerations
Direct substitutes include MMSZ13T1G and MMSZ13T3G from onsemi, which share identical electrical specifications and pinout configurations. Other manufacturers offer equivalent 13V 500mW SOD-123 Zener diodes, but verification of impedance and leakage parameters is required to ensure circuit compatibility.
