Overview
The onsemi 1N5378BRLG is a single-channel Zener voltage regulator diode from the 1N53 Series, designed for through-hole mounting in an axial lead package (CASE 017AA). It features a nominal Zener voltage of 100 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at 25°C. The device operates within a temperature range of -65°C to +200°C and includes silicon-oxide passivated junctions for superior environmental protection.
Feature Summary
- Utilizes silicon-oxide passivated junctions for enhanced reliability and operating characteristics.
- Features surge current ratings up to 180 W at 8.3 ms pulse width.
- Provides ESD protection rated at Class 3 (>16 kV) per the Human Body Model.
Applications
- Voltage regulation circuits requiring high surge capability
- Protection against transient overvoltage events
- General-purpose Zener diode applications in industrial environments
Procurement Notes
Verify that the ordering suffix 'RLG' corresponds to the tape and reel packaging format containing 4000 units per reel. Confirm compliance with RoHS directives and ensure the component meets specific thermal management requirements given the 5 W power dissipation limit at ambient temperatures above 25°C.
Selection Notes
Select this component when a 100 V Zener reference with high surge tolerance is required. Ensure the application circuit can handle the specified maximum leakage current and impedance values. Verify that the axial lead spacing and case dimensions fit the target PCB layout constraints.
Part Context
This part belongs to the 1N53 Series of 5 Watt Zener Voltage Regulators manufactured by onsemi. The series offers a wide voltage range from 3.3 V to 200 V, utilizing transfer-molded plastic packages for robustness in common environmental conditions.
Replacement Considerations
Compatible substitutes include other manufacturers' 1N5378B variants or equivalent 100 V, 5 W Zener diodes in the DO-41/Case 017AA package. Verify electrical parameters such as Zener impedance and leakage current match the original specifications before substitution.
