SMBZ5924B-E3/5B

Single Zener Diodes Overview

The SMBZ5924B-E3/5B is a surface-mount power voltage-regulating diode manufactured by Vishay General Semiconductor. It operates within the SMB (DO-214AA) package and provides a nominal Zener voltage of 9.1 V with a tolerance range of 8.64 V to 9.56 V. The device supports a maximum steady-state power dissipation of 3000 mW at a lead temperature of 75 °C, or 550 mW at an ambient temperature of 25 °C. Electrical characteristics include a maximum Zener impedance of 4.0 Ω at a test current of 41.2 mA, a reverse leakage current of 1000 μA at 7.0 V, and a maximum DC Zener current of 164 mA. The component functions reliably across an operating junction and storage temperature range of -55 °C to +150 °C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging quantity and delivery mode. The /5B suffix indicates a base quantity of 3200 units in a 13-inch diameter plastic tape and reel. Confirm RoHS compliance status and material categorization definitions via the manufacturer's website before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a single configuration Zener diode with a nominal 9.1 V breakdown is required in an SMB package. Ensure the application design accommodates the thermal resistance limits, specifically the typical junction-to-lead thermal resistance of 25 °C/W. Validate that the maximum instantaneous forward voltage and peak pulse power dissipation requirements align with the datasheet parameters for the intended circuit environment.

Single Zener Diodes Part Context

This part belongs to the SMBZ5919B through SMBZ5945B series of surface-mount power voltage-regulating diodes. The series covers a wide Zener voltage range from 5.6 V to 68 V, all housed in the standardized SMB (DO-214AA) case. These devices are designed for general-purpose regulation and protection, offering consistent electrical performance across the family while maintaining low profile and automated placement compatibility.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same Vishay series include SMBZ5923B-E3/5B (8.2 V) and SMBZ5925B-E3/5B (10 V). Verify that the replacement part's Zener voltage tolerance and maximum power dissipation ratings match the original circuit design constraints.
