1N4732A-T Description

Short technical summary and product information.

The 1N4732A-T is a 1.0W Zener diode from Diodes Incorporated, part of the 1N4728A-1N4761A series. It features a nominal Zener voltage of 4.7V at a test current of 53mA, with a tolerance of ±5%. The maximum Zener impedance at IZT is 8Ω, and at IZK (1mA) it is 500Ω. The maximum reverse leakage current is 10µA at 1V reverse voltage. The device can handle a surge current of 970mA for 8.3ms.

 

Packaged in a DO-41 (DO-204AL) glass axial-lead case, the diode is suitable for through-hole mounting. It has a lead-free finish (Sn96.5Ag3.5) and is RoHS compliant with certain exemptions. The operating temperature range is -65°C to 175°C, with a power dissipation derating of 6.67mW/°C above 50°C. The thermal resistance from junction to ambient is 175°C/W.
