SMZJ3792B-M3/5B

Single Zener Diodes Overview

The SMZJ3792B-M3/5B is a surface mount power voltage-regulating diode manufactured by Vishay General Semiconductor. It features a glass passivated chip junction and operates within the SMB (DO-214AA) package. The nominal Zener voltage is 13 V, with a maximum power dissipation of 1500 mW. Electrical characteristics include a test current of 28.8 mA, a maximum Zener impedance of 7.5 Ω at the test current, and a maximum reverse current of 5.0 μA at 9.9 V. The device supports an operating junction temperature range from -55 °C to +150 °C.

Single Zener Diodes Feature Summary

• Glass passivated chip junction for enhanced reliability
• Low Zener impedance and low regulation factor
• Ideal for automated placement in surface mount applications
• Halogen-free and RoHS-compliant commercial grade construction

Single Zener Diodes Applications

• General purpose voltage regulation
• Industrial circuit protection
• Overvoltage suppression

Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix to confirm the delivery mode and reel diameter. The /5B designation indicates a 13-inch diameter plastic tape and reel with a base quantity of 3200 units. Confirm that the M3 suffix aligns with halogen-free requirements. Ensure the procurement documentation matches the exact document number 88402 for accurate specifications.

Single Zener Diodes Selection Notes

Select this component when a 13 V reference or clamp is required in a compact surface mount footprint. The SMB package provides adequate thermal handling for 1500 mW dissipation. Verify that the 7.5 Ω dynamic impedance meets the noise and regulation requirements of the target circuit. Consider the -55 °C to +150 °C operating range for environmental suitability.

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 members share the same DO-214AA mechanical outline and general electrical testing conditions, differing primarily in their specific breakdown voltage and associated test currents.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same Vishay series include other SMZJ37xxB variants if the voltage rating differs. For automotive applications, verify availability of AEC-Q101 qualified versions such as the SMZJ3792BHE3_B or SMZJ3792BHM3_B.
