1SMB5931B-13 Description

Short technical summary and product information.

The 1SMB5931B-13 is a 18V Zener diode from Diodes Incorporated, part of the 1SMB59xxB series of 3.0W surface mount power Zener diodes. It offers a nominal Zener voltage of 18V with a tolerance of ±5%. The device is designed for automated assembly and is housed in a DO-214AA (SMB) package with a matte tin finish.

 

Key electrical characteristics include a maximum forward voltage of 1.5V at 200mA, a maximum reverse current of 1µA at 13.7V, and a maximum impedance (Zzt) of 12Ω at the test current. The diode can dissipate up to 3.0W at a lead temperature of +75°C (derated at 40mW/°C above that) and 550mW at an ambient temperature of +25°C (derated at 4.4mW/°C above that). It operates over a temperature range of -65°C to +150°C.

 

The device is ESD rated to Class 3 (>16kV) per the Human Body Model, has a moisture sensitivity level of 1 (unlimited) per J-STD-020, and a flammability rating of UL 94V-0. It is RoHS3 compliant, lead-free, halogen and antimony free, and a green device. The approximate weight is 0.096 grams.
