Overview
The onsemi 1N5381BG is a 5 Watt Zener voltage regulator diode belonging to the 1N53 Series. It features silicon-oxide passivated junctions and is housed in an axial lead, transfer-molded plastic package (Surmetic 40). The nominal Zener voltage is 130 V with a tolerance of ±5%. Key electrical characteristics include a maximum Zener impedance of 190 Ohms at a test current of 10 mA, a reverse leakage current of 0.5 µA at 98.8 V, and a maximum steady-state power dissipation of 5 W at 25°C.
Feature Summary
- Utilizes silicon-oxide passivated junctions for superior operating characteristics and environmental protection.
- Provides tight voltage limits and guaranteed maximums on multiple electrical parameters.
- Features high surge capability up to 180 W for short durations.
Applications
- Voltage regulation circuits
- Overvoltage protection systems
- Reference voltage generation
Procurement Notes
Verify that the ordering suffix 'G' corresponds to the Pb-Free package designation as defined in the official datasheet. Confirm the specific device marking matches the 1N5381B identifier. Ensure the component meets the required RoHS compliance standards for your assembly process.
Selection Notes
Select this component when a precise 130 V reference or regulation point is required within a 5 Watt power dissipation envelope. The axial lead format facilitates through-hole mounting. Consider the thermal resistance characteristics and derating requirements above 25°C for continuous operation.
Part Context
This part belongs to the 1N53 Series of 5 Watt Zener regulators from onsemi. The series covers a wide voltage range from 3.3 V to 200 V. The 'B' suffix indicates a ±5% tolerance, while the 'G' suffix denotes a lead-free package option within the Surmetic 40 case outline.
Replacement Considerations
Compatible substitutes include other manufacturers' 1N5381B variants. Verify that any replacement maintains the 130 V nominal voltage, 5 W power rating, and axial lead package dimensions to ensure mechanical and electrical compatibility.
