1N746A Description

Short technical summary and product information.

The 1N746A is a 3.3V Zener diode from Microchip Technology designed for voltage regulation and clamping applications. It offers a nominal zener voltage of 3.3V at a test current of 20mA with a tolerance of ±5%. The device can dissipate up to 500mW of power at lead temperatures up to 75°C, with a derating factor of 4.0 mW/°C above that point.

 

Electrical characteristics include a maximum impedance (Zzt) of 28Ω at the test current, a forward voltage of 1.5V maximum at 200mA, and a reverse leakage current of 10µA at 1V. The diode operates over a wide temperature range from -65°C to +200°C.

 

The 1N746A is housed in a DO-35 (DO-204AH) glass case with axial leads for through-hole mounting. The cathode is identified by a color band on the body. This package is suitable for automated insertion and hand soldering in a variety of electronic assemblies.
