1N4732 Daesan Electronics Corp., 1N4732 Datasheet - Page 2

• Manufacturer Part Number: 1N4732
• Description: 1w Silicon Planar Zener Diodes
• Manufacturer: Daesan Electronics Corp.

Notes:
1) The zener impedance is derived from the 1kHz AC voltage which results when on AC current having an RMS value equal to 10% of the Zener
2) Vaild provided that electrodes at a distance of 10mm from case are kept at ambient temperature.
3) Measured under thermal equilibrium and DC test conditions.
