Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required tape and reel dimensions, as the TR13 designation indicates a 13-inch reel configuration containing 12,000 pieces. Confirm RoHS compliance status directly from the manufacturer datasheet, as environmental compliance varies across product lines. Ensure the procurement documentation references the correct Microsemi or Microchip Technology part number to avoid substitution errors.

Single Zener Diodes Selection Notes

Select this component when high power handling capabilities are needed in a compact surface mount footprint. The Powermite package offers superior thermal performance compared to standard plastic packages due to its metallic base. Consider the specific Zener voltage and tolerance requirements against the available series options. Verify that the application environment supports the specified operating temperature range and mounting constraints.
