Overview
The onsemi 1N5370BRLG is a 56 V Zener voltage regulator diode with a ±5% tolerance, rated for 5 W steady-state power dissipation. It operates within a junction temperature range of -65 °C to +200 °C and features a maximum reverse leakage current of 500 nA at 42.6 V. The device utilizes an axial lead DO-15 (Case 017AA) package and is supplied in tape and reel format.
Feature Summary
- Utilizes silicon-oxide passivated junctions for superior operating characteristics and environmental protection.
- Provides high surge current capability up to 180 W for an 8.3 ms pulse width.
- Features ESD protection rated at Class 3 (>16 kV) per the Human Body Model.
Applications
- Voltage regulation circuits requiring stable reference voltages.
- Protection against transient overvoltage events in electronic systems.
- Surge suppression applications involving non-repetitive square-wave currents.
Procurement Notes
Verify that the ordering suffix 'RLG' corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm compliance with RoHS directives and Pb-Free status by reviewing the manufacturer's material declaration or datasheet revision history before finalizing procurement specifications.
Selection Notes
Select this component when a precise 56 V regulation point is necessary alongside robust thermal handling capabilities. Ensure the application circuit can accommodate the specified maximum DC Zener current of 86 mA without exceeding the 5 W power dissipation limit at the intended ambient temperature.
Part Context
This part belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators. The series offers a wide voltage range from 3.3 V to 200 V in a single axial lead plastic package designed for reliable performance across diverse industrial and commercial environments.
Replacement Considerations
Cross-reference with other manufacturers offering the standard 1N5370B designation. Verify that alternative sources provide identical electrical parameters, specifically the 56 V nominal voltage, 5 W power rating, and compatible DO-15 axial lead package dimensions.
