Single Zener Diodes Procurement Notes

Verify the specific suffix 'E3' against official documentation to confirm lead-free compliance status, as datasheets may reference general family attributes. Confirm that the tape and reel packaging adheres to EIA Standard 481 specifications. Ensure the procurement quantity aligns with the manufacturer's factory pack size requirements for this component series.

Single Zener Diodes Selection Notes

Select this component when a 160 V Zener voltage is required in a compact surface mount form factor. The Powermite package offers superior thermal performance compared to standard axial packages due to its metallic base. Verify that the application circuit can accommodate the specified dynamic impedance and reverse leakage characteristics at the intended operating temperature.

Single Zener Diodes Part Context

This part belongs to the 1PMT59xxB series of 3-watt Zener diodes manufactured by Microchip Technology (formerly Microsemi). The series spans voltages from 3.3 V to 200 V, all sharing the same DO-216AA mechanical footprint. The 'E3' designation typically indicates a lead-free finish, while '/TR13' specifies the 13-inch tape and reel packaging format containing 12,000 pieces.
