Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm compliance status, as variations exist between commercial grade and AEC-Q101 qualified automotive versions. Ensure the base part number matches the required voltage and tolerance specifications before procurement. Cross-reference datasheet revision dates to confirm current manufacturing parameters.

Single Zener Diodes Selection Notes

Select this component when a 36 V regulation point is required in a compact surface mount form factor. Consider the 1500 mW power dissipation capability and the -55 °C to +150 °C operating temperature range for environmental suitability. Evaluate the 38 Ω dynamic impedance for noise-sensitive applications requiring stable voltage clamping.

Single Zener Diodes Part Context

This component belongs to the SMZJ3788B through SMZJ3809B series of surface mount power voltage-regulating diodes. The series utilizes the SMB (DO-214AA) case configuration and offers a wide range of Zener voltages from 9.1 V to 68 V. All devices in this family share similar mechanical and electrical characteristics, differing primarily in their specific voltage ratings and corresponding test currents.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other SMZJ38xxB variants if voltage requirements differ. For automotive applications, verify availability of the HE3 or HM3 qualified equivalents. Ensure any replacement maintains the DO-214AA footprint and meets the necessary thermal and electrical performance criteria.
