Overview
The onsemi 1N5348BG is a 5 Watt Zener voltage regulator diode with a nominal breakdown voltage of 11 V. It utilizes silicon-oxide passivated junctions and is housed in an axial lead Surmetic 40 (DO-201AE) plastic package. The device operates within a temperature range of -65°C to +200°C, with a maximum steady-state power dissipation of 5 W at 25°C. Electrical characteristics include a reverse current of 125 mA, a maximum impedance of 2.5 Ω at test current, and a surge rating of up to 180 W for 8.3 ms pulses.
Feature Summary
- Utilizes silicon-oxide passivated junction technology for superior operating characteristics
- Features built-in strain relief within the transfer-molded plastic case
- Provides high ESD protection rated at Class 3 (>16 kV) per Human Body Model
- Offers guaranteed maximum limits on multiple electrical parameters
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement systems
Procurement Notes
Verify that the ordering suffix 'G' corresponds to the Pb-Free package configuration as specified in the datasheet. Confirm the specific part number matches the required JEDEC tolerance designation. Ensure the component meets the environmental requirements for the intended application before procurement.
Selection Notes
Select this component when a 5 Watt power rating and an 11 V nominal Zener voltage are required. Consider the axial lead package for through-hole mounting applications. Evaluate the thermal resistance and derating curves if operation above 25°C ambient temperature is anticipated.
Part Context
This device belongs to the 1N53 Series of 5 Watt Zener Voltage Regulators manufactured by onsemi. The series provides a wide selection of voltages from 3.3 V to 200 V in a robust axial lead package designed for common environmental conditions.
Replacement Considerations
Compatible substitutes include other manufacturers' 1N5348B variants. Verify that replacement parts match the 5 W power rating, 11 V nominal voltage, and DO-201AE package dimensions.
