SMZJ3806BHM3/H

Single Zener Diodes Overview

The SMZJ3806BHM3/H is a surface mount power voltage-regulating diode manufactured by Vishay General Semiconductor. It operates within the SMZJ3788B through SMZJ3809B series and utilizes an SMB (DO-214AA) package. The nominal Zener voltage is 51 V with a tolerance of ±5%. Maximum steady-state power dissipation is 1500 mW at a lead temperature of 75 °C. The device features a maximum reverse current of 5 µA at 38.8 V and a maximum Zener impedance of 70 Ω at a test current of 7.3 mA. It supports a maximum Zener current of 24 mA and operates across a junction and storage temperature range of -55 °C to +150 °C.

Single Zener Diodes Procurement Notes

Verify component authenticity and datasheet revision prior to procurement. Confirm that the HM3 suffix indicates halogen-free compliance and AEC-Q101 qualification. Validate package dimensions against PCB footprint requirements. Ensure thermal management aligns with derating curves for ambient temperatures exceeding 25 °C. Check for specific ordering codes matching required reel quantities.

Single Zener Diodes Selection Notes

Select this component when a 51 V reference or clamp is required in space-constrained surface mount designs. The SMB package provides higher power handling than smaller signal diodes. Verify that the 70 Ω impedance meets noise-sensitive application limits. Consider the AEC-Q101 qualification if the design targets automotive environments requiring specific reliability standards.

Single Zener Diodes Part Context
