Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required tape and reel packaging configuration. Confirm the exact voltage tolerance level (standard, 2%, or 1%) as indicated by any additional part number characters. Ensure the procurement specification aligns with the commercial grade RoHS compliance status if applicable.

Single Zener Diodes Selection Notes

Select this component when a 20 V reference is required in an axial-lead form factor. Consider the positive temperature coefficient for thermal stability requirements. Evaluate the 500 mW power dissipation limit against the expected operating current to ensure adequate derating margins are maintained.
