ZGL41-120A-E3/97 is listed in the Single Zener Diodes range at ChipApex. The manufacturer field lists Vishay General Semiconductor - Diodes Division. Its product description is DIODE ZENER 120V 1W DO213AB. Review the specifications below when checking this part for your BOM.
The ZGL41-120A-E3/97 is a surface mount glass passivated power voltage-regulating diode manufactured by Vishay General Semiconductor. It operates within the ZGL41 series, providing a nominal Zener voltage of 120 V with a test current of 3.1 mA and a maximum impedance of 380 Ohms at that current. The device dissipates up to 1 W of power and withstands a maximum surge current of 8.3 A. It features a GL41 (DO-213AB) package, operates between -55 °C and +150 °C, and meets MSL level 1 requirements.
Verify component authenticity through authorized channels. Confirm RoHS compliance status and check for specific suffix variations like M3 regarding whisker testing. Validate datasheet revision dates against manufacturing batches to ensure accurate electrical parameters are applied during design integration.
Select this component when a 120 V reference is required in a compact SMD form factor. Ensure thermal management accommodates the 1 W dissipation limit above 75 °C lead temperature. Verify that the 380 Ohm dynamic impedance aligns with circuit sensitivity requirements.
This part belongs to the ZGL41 series of surface mount power Zener diodes ranging from 100 V to 200 V. The series utilizes a GL41 (DO-213AB) case designed for high-reliability applications requiring robust transient handling and stable voltage regulation in space-constrained environments.
Direct substitutes include other Vishay ZGL41-120 variants such as ZGL41-120A-E3/76 or ZGL41-120A/76, provided the reel quantity and tape specifications match the assembly line requirements.
