Overview
The onsemi 1N5380BG is a silicon-oxide passivated junction Zener voltage regulator diode rated for 5 W steady-state power dissipation. It features a nominal Zener voltage of 120 V with a ±5% tolerance, operating within a range of 114 V to 126 V at a test current of 10 mA. The device utilizes an axial lead Surmetic 40 (CASE 017AA) plastic package and supports an operating temperature range from -65°C to +200°C.
Feature Summary
- Utilizes silicon-oxide passivated junctions for superior electrical characteristics and environmental protection.
- Provides high surge capability with ratings up to 180 W for 8.3 ms pulses.
- Offers robust electrostatic discharge (ESD) protection exceeding 16 kV per the Human Body Model.
Applications
- Voltage regulation in general-purpose electronic circuits
- Protection against transient overvoltage events
- Reference voltage generation in power supplies
Procurement Notes
Verify that the ordering suffix 'G' corresponds to the Pb-Free package configuration as defined by onsemi standards. Confirm the specific part number matches the required JEDEC type designation and ensure compliance with RoHS directives if applicable to your manufacturing process.
Selection Notes
Select this component when a 120 V Zener reference is required with tight ±5% tolerance limits. Ensure the application can accommodate the 5 W thermal dissipation requirements and verify that the axial lead mounting style fits the mechanical constraints of the target PCB layout.
Part Context
This device belongs to the 1N53 Series of 5 Watt Zener Voltage Regulators manufactured by onsemi. The series covers a broad voltage spectrum from 3.3 V to 200 V, utilizing transfer-molded plastic packages designed for reliability in common environmental conditions.
Replacement Considerations
Compatible equivalents include other manufacturers' 1N5380B variants. Verify that substitute parts maintain the same 5 W power rating, 120 V nominal voltage, and axial lead package dimensions to ensure direct interchangeability without circuit modification.
