1SMB5925BT3G

Single Zener Diodes Overview

The onsemi 1SMB5925BT3G is a single-channel Zener voltage regulator diode designed for surface-mount applications. It features a nominal Zener voltage of 10 V with a ±5% tolerance, operating within a range of 9.5 V to 10.5 V. The device supports a maximum steady-state power dissipation of 3 W at a lead temperature of 75°C and 550 mW at an ambient temperature of 25°C. It utilizes the SMB (DO-214AA) package and operates across a temperature range from -65°C to +150°C.

Single Zener Diodes Feature Summary

• Flat handling surface facilitates accurate placement during automated assembly processes.
• Package design allows for both top-side and bottom-side circuit board mounting configurations.
• ESD rating meets Class 3 standards exceeding 16 kV per the Human Body Model.

Single Zener Diodes Applications

Single Zener Diodes Procurement Notes

Verify that the specific order includes the 'G' suffix to confirm Pb-Free compliance as specified in the datasheet. Ensure the SZ prefix is included if automotive qualification and PPAP capability are required for the application. Confirm the tape and reel packaging specifications match the production line requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 10 V reference or regulation point is needed in a compact surface-mount footprint. Consider the thermal derating characteristics carefully if the operating environment exceeds 25°C ambient temperature. Evaluate the low leakage current and impedance specifications against the specific noise and stability requirements of the target circuit design.

Single Zener Diodes Part Context

This part belongs to the 1SMB59xxBT3G series of 3 Watt plastic surface mount Zener voltage regulators. The series covers a wide voltage range from 3.3 V to 200 V, providing designers with standardized options for various regulation needs. All devices in this family share the same SMB mechanical outline and similar electrical testing conditions.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering SMB packaged Zener diodes rated at 10 V and 3 W. Verify that any substitute matches the exact ±5% voltage tolerance and dynamic impedance specifications to ensure circuit performance consistency without redesigning the surrounding components.
