SMAZ18-13-F Description

Short technical summary and product information.

The SMAZ18-13-F is a 18V Zener diode from Diodes Incorporated, part of the SMAZ series. It features a nominal Zener voltage of 18V with a tolerance of ±5%. The device can dissipate up to 1W of power at an ambient temperature of +50°C, with derating of 10 mW/°C above that temperature. Electrical characteristics include a forward voltage of 1.2V at 200mA, a maximum reverse leakage current of 500 nA at 13.7V, and a maximum Zener impedance of 15Ω. The operating temperature range spans from -65°C to 150°C.

 

The diode is housed in a surface mount DO-214AC (SMA) package, making it suitable for automated assembly. The package is molded plastic with UL 94V-0 flammability rating, and the terminals have a matte tin finish for solderability. The device is RoHS3 compliant, lead-free, and halogen-free (green). Moisture sensitivity level is 1 (unlimited) per J-STD-020. Typical applications include voltage regulation, overvoltage protection, and voltage reference circuits in various electronic systems.
