Single Zener Diodes Procurement Notes

Verify the specific suffix HE3-TR3 against the manufacturer's latest datasheet to confirm compliance with current environmental directives such as RoHS3. Ensure the DO-214AC footprint matches the design layout. Confirm that the ±2% tolerance aligns with circuit requirements, as standard variants may differ. Cross-reference the part number with official distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 91 V Zener voltage with tight ±2% tolerance is required in a surface-mount format. The 1.25 W power rating suits moderate power dissipation needs. Consider the 250 Ohm impedance for dynamic response requirements. Verify compatibility with operating temperatures up to 150°C. Compare against other BZG05 series variants if different voltage or tolerance specifications are needed for the specific application constraints.

Single Zener Diodes Part Context

This component belongs to the BZG05 series of single Zener diodes from Vishay. The series offers various voltage ratings within the DO-214AC package. The BZG05B91 variant specifically targets the 91 V market segment. Similar parts in the lineup include BZG05C36-HM3_A-08 and BZG05B11-E3-TR, offering different voltages and tolerances within the same physical form factor and power class.

Single Zener Diodes Replacement Considerations

Official parameter-equivalent replacements include BZG05B91-M3-18 and BZG05B91-M3_A-18. These alternatives maintain the same 91 V, 1.25 W, and DO-214AC specifications. Verify pinout compatibility and thermal performance before substitution. Ensure the replacement part meets the same ±2% tolerance and 150°C junction temperature requirements.
