1SMB5928 R5G

Single Zener Diodes Overview

The Taiwan Semiconductor 1SMB5928 R5G is a surface-mount Zener diode in the DO-214AA (SMB) package. It features a nominal Zener voltage of 13V with a 5% tolerance, operating within a range of 12.35V to 13.65V. The device handles a total power dissipation of 3W and has a maximum DC Zener current of 9.9mA. Electrical characteristics include a test current of 28.8mA, a maximum Zener impedance of 7.0Ω at IZT, and a leakage current of 0.25μA at VR=9.9V. The junction temperature rating extends from -55°C to +150°C.

Single Zener Diodes Procurement Notes

Verify the specific ordering code matches the required voltage variant within the 1SMB5926–1SMB5956 series. Confirm that the 'R5G' suffix aligns with the manufacturer's standard tape and reel packaging configuration. Ensure compliance requirements such as RoHS and halogen-free status are documented for your supply chain records before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 13V regulation point is needed in a compact SMB footprint. The 3W power rating supports moderate current handling, while the low inductance benefits high-frequency switching environments. Verify that the thermal derating curves accommodate the expected ambient temperatures and PCB copper pad sizes for optimal heat dissipation.

Single Zener Diodes Part Context

This part belongs to the 1SMB5926 through 1SMB5956 series, which covers a wide Zener voltage range from 11V to 200V. All devices in this family share the same DO-214AA mechanical outline and glass-passivated junction technology. The series is designed for automated placement and offers consistent performance characteristics across different voltage ratings.

Single Zener Diodes Replacement Considerations

Other parts in the 1SMB5926–1SMB5956 series may serve as substitutes if voltage tolerances allow. Cross-manufacturer replacements must match the DO-214AA package, 3W power rating, and 13V nominal Zener voltage. Verify that alternative components meet the same leakage and impedance specifications.
