Procurement Notes

Verify the specific ordering suffix _R2_00001 corresponds to Tape and Reel packaging on a 13-inch reel with RoHS compliance. Confirm that the manufacturer's datasheet for the 1N5338B series accurately reflects the electrical parameters for the 1N5355B variant. Ensure all procurement documentation matches the JEDEC DO-201AE mechanical dimensions and terminal solderability standards specified by MIL-STD-750, Method 2026.

Selection Notes

Select this component when a 5-watt power rating and an 18-volt reference are required. The DO-201AE package supports higher thermal dissipation compared to smaller glass packages. Verify that the operating environment remains within the specified -55°C to +150°C temperature range. Consider the low leakage current characteristics for precision applications where minimal current drain is critical.

Part Context

This part belongs to the 1N5338B series of silicon Zener diodes produced by Panjit International Inc. The series covers a voltage range from 5.1V to 51V with consistent 5-watt power handling capabilities. The 1N5355B specifically targets the 18-volt segment of this lineup, offering standardized performance metrics aligned with other members of the family for consistent design integration.

Replacement Considerations

Cross-reference with other manufacturers' 1N5355B equivalents to ensure pinout compatibility and thermal derating curves match the original specifications. Verify that substitute components meet the same 94V-O flammability classification and RoHS 2.0 compliance requirements.
