1N5356BRLG

Overview

The onsemi 1N5356BRLG is a silicon-oxide passivated Zener voltage regulator with a nominal voltage of 19 V and ±5% tolerance. It operates in an axial lead DO-15 (Surmetic 40) package, rated for 5 W steady-state power dissipation at 25°C. Key electrical parameters include a test current of 65 mA, maximum impedance of 75 Ω, and leakage current of 0.5 mA at 14.4 V. The device withstands up to 180 W surge power at 8.3 ms and offers ESD protection exceeding 16 kV per the Human Body Model.

Feature Summary

• Utilizes silicon-oxide passivated junctions for tight limits and superior operating characteristics.
• Features void-free, transfer-molded plastic packaging providing corrosion resistance and environmental protection.
• Includes high surge capability and robust electrostatic discharge (ESD) ratings.

Applications

• Voltage regulation in electronic circuits
• Overvoltage protection applications
• Reference voltage generation

Procurement Notes

Verify that the ordering suffix 'RLG' corresponds to the tape and reel packaging format containing 4000 units per reel. Confirm the presence of the 'G' suffix indicates a Pb-Free package compliant with relevant standards. Ensure the component matches the Surmetic 40 mechanical outline specifications before integration into the assembly process.

Selection Notes

Select this component when a 19 V reference with ±5% precision is required in a high-power 5 W axial package. Consider the thermal resistance characteristics and derating requirements above 25°C. Evaluate the specific impedance and leakage values against circuit sensitivity needs compared to other voltages within the 1N53 series.

Part Context

This part belongs to the 1N53 Series of 5 Watt Zener diodes manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V using JEDEC registered type numbers. The 'B' suffix designates a ±5% tolerance level, while the 'RLG' suffix specifies the reel packaging configuration for automated assembly.

Replacement Considerations

Compatible substitutes include the 1N5356B and 1N5356BG variants from onsemi or Microsemi. Cross-manufacturer equivalents such as the MSP1N5356B are available. Verify that replacement parts maintain the same 5 W power rating, DO-15 package dimensions, and 19 V nominal voltage specification.
