1N5358B_R2_00001

Overview

The 1N5358B_R2_00001 is a silicon unidirectional voltage regulator diode from the 1N5338B series manufactured by Panjit International Inc. It features a nominal Zener voltage of 22 V with a tolerance range of 20.9 V to 23.1 V. The device operates within a DC power dissipation rating of 5 Watts at 75°C ambient temperature and supports an operating junction and storage temperature range from -55°C to +150°C. Electrical characteristics include a maximum Zener impedance of 4 Ω at 50 mA test current and a maximum leakage current of 0.5 µA at 16.7 V reverse voltage. The component utilizes a JEDEC DO-201AE molded plastic case with axial leads.

Feature Summary

• Glass passivated junction for enhanced stability
• Low inductance design suitable for high-frequency applications
• Plastic package meets Underwriters Laboratory Flammability Classification 94V-O
• Lead-free construction compliant with EU RoHS 2.0 directives

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• General-purpose rectification and clamping

Procurement Notes

Verify the specific ordering suffix R2_00001 corresponds to Tape and Reel packaging on a 13-inch reel, as indicated by the manufacturer's packing code definitions. Confirm that the version code denotes compliance with RoHS standards. Ensure the lot number is recorded for tracking purposes, as Panjit uses lot numbers as the primary basis for product traceability during quality inquiries.

Selection Notes

Select this component when a 22 V reference or regulation point is required in through-hole designs. The 5 W power rating allows for significant thermal handling compared to lower-power variants. Verify that the DO-201AE axial lead form factor fits the target PCB layout constraints. Consider the 4 Ω impedance specification for applications requiring moderate voltage stability under varying load currents.

Part Context

This part belongs to the 1N5338B series, which covers nominal Zener voltages ranging from 5.1 V to 51 V. All devices in this series share identical mechanical data, including the DO-201AE case and glass-passivated junction technology. The series is designed for general-purpose voltage regulation tasks where standard axial mounting is preferred over surface-mount alternatives.

Replacement Considerations

Cross-reference with other manufacturers' 1N5358B parts to ensure pinout compatibility and electrical parameter alignment. Verify that substitute components meet the same 5 W power dissipation and -55°C to +150°C temperature range requirements. Check for equivalent Zener impedance and leakage current specifications to maintain circuit performance integrity.
