Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'C' suffix to ensure the component meets the required ±2% tolerance specification. Confirm the '-TR' suffix indicates reel packaging if automated assembly is planned. Cross-reference the document number 85588 to access the latest technical specifications and ensure compliance with current manufacturing standards.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical due to its narrow tolerance band. The DO-35 package suits through-hole applications requiring reliable axial mounting. Evaluate the negative temperature coefficient to determine if compensation is necessary for stable operation across varying ambient temperatures.

Single Zener Diodes FAQ

What does the 'C' suffix indicate in the part number?

The 'C' suffix specifies a Zener voltage tolerance of ±2%, which is tighter than the standard ±5% tolerance found in the 'B' suffix variant.

What is the maximum power dissipation rating?

The maximum power dissipation is 500 mW at an ambient temperature of 25 °C, provided the lead length is maintained at 4 mm.
