SZ1SMB5925BT3G

Single Zener Diodes Overview

The SZ1SMB5925BT3G is a single-channel Zener voltage regulator diode from onsemi, designed for surface-mount applications in the SMB (DO-214AA) package. It features a nominal Zener voltage of 10 V with a ±5% tolerance and operates within a reverse current range defined by its electrical characteristics table. The device supports a maximum steady-state power dissipation of 3.0 W at lead temperatures up to 75°C, or 550 mW at ambient temperatures of 25°C. It is qualified under AEC-Q101 standards and offers an operating temperature range from -65°C to +150°C.

Single Zener Diodes Feature Summary

• AEC-Q101 qualified and PPAP capable for automotive and high-reliability applications
• ESD rating of Class 3 exceeding 16 kV per Human Body Model
• Flat handling surface design facilitates accurate automated placement
• Package geometry allows for both top-side and bottom circuit board mounting

Single Zener Diodes Applications

• Automotive electronic systems requiring unique site control
• Voltage regulation circuits in industrial environments
• Protection stages in consumer electronics assemblies

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the 'SZ' prefix to confirm AEC-Q101 qualification and PPAP capability. Ensure the ordering suffix matches the required tape and reel specifications. Confirm compliance with RoHS directives and Pb-Free status as documented in the manufacturer's datasheet before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 10 V reference is needed in a surface-mount SMB package. Consider the thermal derating curves if operating above 25°C ambient temperature. Verify that the required ESD protection level meets the Class 3 standard for the target application environment.

Single Zener Diodes Part Context

This device belongs to the 1SMB59xxBT3G and SZ1SMB59xxT3G series of 3 Watt plastic surface mount Zener voltage regulators. The series provides a complete voltage range from 3.3 V to 200 V. The SZ prefix specifically denotes devices manufactured for automotive and other applications requiring unique site and control change requirements.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1SMB5925BT3G and 1SMB5925BT3G variants within the same series. Verify that replacement parts meet the same AEC-Q101 qualification and package dimensions.
