1N5368BRLG

Overview

The onsemi 1N5368BRLG is a single-channel Zener voltage regulator diode from the 1N53 Series, housed in an axial lead DO-15 (Surmetic 40) plastic package. It features a nominal Zener voltage of 47 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 a polarity band for cathode identification.

Feature Summary

• Utilizes silicon-oxide passivated junctions for tight electrical limits and superior operating characteristics.
• Features void-free, transfer-molded thermosetting plastic packaging that provides corrosion resistance and environmental protection.
• Includes built-in strain relief and low inductance design suitable for high DC currents with adequate heat sinking.

Applications

• Voltage regulation circuits requiring stable reference voltages.
• Protection against transient overvoltage conditions.
• General-purpose electronic equipment utilizing axial lead components.

Procurement Notes

Verify the specific ordering suffix 'RLG' corresponds to the tape and reel configuration containing 4000 units per reel. Confirm the presence of the 'G' suffix indicates Pb-Free compliance as defined by the manufacturer's soldering and mounting techniques manual. Ensure the component marking matches the standard assembly location and year/work week format.

Selection Notes

Select this component when a 47 V Zener voltage with ±5% tolerance is required in a 5 W axial lead package. Consider the thermal resistance characteristics and the maximum surge current rating for transient protection applications. Verify that the operating environment falls within the specified -65°C to +200°C temperature range.

Part Context

This part belongs to the 1N53 Series of 5 Watt Zener diodes, which covers a voltage range from 3.3 V to 200 V. The series is characterized by JEDEC registration and offers various tolerance options identified by specific suffix letters. The 1N5368B variant specifically targets the 47 V nominal voltage segment of this comprehensive lineup.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N5368B equivalents meeting the same 47 V, 5 W, and ±5% specifications. Cross-reference with Microsemi or Panasonic variants if available, ensuring identical package dimensions and electrical parameters are maintained for direct replacement.
