Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required reliability level and RoHS compliance status. Confirm the package type corresponds to the intended mounting method. Ensure the requested tolerance aligns with the circuit requirements before finalizing the purchase order.

Single Zener Diodes Selection Notes

Select this component when a 68-volt breakdown voltage is required in a through-hole glass package. Consider the thermal derating characteristics for power dissipation limits above ambient temperatures. Evaluate the dynamic impedance specifications against the noise sensitivity of the target application.

Single Zener Diodes Part Context

This part belongs to the 1N3016B-1 through 1N3045B-1 series of 1-watt Zener diodes. These devices are JEDEC registered and qualified per MIL-PRF-19500/115 standards. The series provides a wide selection of voltages from 6.8 to 110 volts in a standard DO-41 package.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N3040B equivalents meeting the same electrical and mechanical specifications. Verify compatibility regarding lead finish and hermetic seal requirements for critical applications.
