SMZJ3792BHE3/5B

Single Zener Diodes Overview

The SMZJ3792BHE3/5B is a surface mount power voltage-regulating diode manufactured by Vishay General Semiconductor. It features a nominal Zener voltage of 13 V with a ±5% tolerance and a maximum power dissipation of 1.5 W. The device utilizes a glass passivated chip junction within an SMB (DO-214AA) plastic package. Electrical characteristics include a maximum dynamic impedance of 7.5 Ω at a test current of 28.8 mA, and a maximum reverse leakage current of 5 μA at 9.9 V. It operates within a temperature range of -55 °C to +150 °C.

Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix to confirm the delivery mode and base quantity. The HE3 designation indicates RoHS compliance and AEC-Q101 qualification. Confirm that the required tape and reel diameter matches the manufacturing standard for the selected variant before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 13 V reference or clamp is required in a compact surface mount footprint. Ensure the application accounts for the 1.5 W steady-state power dissipation limit at elevated lead temperatures. Verify that the 7.5 Ω dynamic impedance meets the circuit's noise and regulation requirements.

Single Zener Diodes Part Context

This part belongs to the SMZJ3788B through SMZJ3809B series of surface mount power voltage-regulating diodes. The series covers a wide Zener voltage range from 9.1 V to 68 V. All devices share the same SMB (DO-214AA) mechanical outline and utilize glass passivation technology for consistent performance across the product line.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same Vishay series include other variants such as the SMZJ3791BHE3/5B or SMZJ3793BHE3/5B if different voltage levels are acceptable. Cross-manufacturer replacements must match the DO-214AA package dimensions and verify equivalent Zener voltage and power dissipation ratings.
