The 1N4728A-T is a 3.3V Zener diode from Diodes Incorporated, designed for general-purpose voltage regulation and clamping applications. It offers a nominal Zener voltage of 3.3V at a test current of 76 mA, with a tolerance of ±5%. The device can dissipate up to 1W of power, making it suitable for low-power circuits.
Key electrical characteristics include a maximum Zener impedance of 10 Ω at IZT and 400 Ω at IZK, a maximum reverse leakage current of 100 µA at 1V, and a forward voltage of 1.2V at 200 mA. The diode can handle a surge current of up to 1380 mA for 8.3 ms. The operating temperature range spans -65°C to 175°C.
The device is housed in a DO-41 (DO-204AL) through-hole package with axial leads. The case is made of glass with a tin-silver (Sn96.5Ag3.5) terminal finish. Polarity is indicated by a cathode band. The component weighs approximately 0.35 grams.
The datasheet for the 1N4728A-1N4761A series indicates that these parts are obsolete and discontinued. No alternate part is listed. Compliance includes RoHS3 and lead-free finish.
