1N5369B_R2_00001

Overview

The 1N5369B_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 51 V with a tolerance range of 48.45 V to 53.55 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 27 Ω at a test current of 25 mA, a maximum leakage current of 0.5 mA at 38.8 V, and a typical reverse current below 1 µA above 13 V. The component utilizes a JEDEC DO-201AE molded plastic case with axial leads.

Feature Summary

• Utilizes a low-inductance design for stable voltage regulation performance
• Encased in a plastic package compliant with Underwriters Laboratory Flammability Classification 94V-O
• Manufactured in compliance with EU RoHS 2.0 standards for lead-free construction

Applications

• General-purpose voltage regulation circuits
• Power supply protection stages
• Reference voltage generation in electronic systems

Procurement Notes

Verify that the ordering suffix _R2_00001 corresponds to Tape and Reel packaging on a 13-inch reel with RoHS compliance as defined in the manufacturer's packing code documentation. Confirm the specific lot number tracking requirements when requesting samples or bulk orders. Ensure the procurement specifications align with the absolute maximum ratings provided in the datasheet to prevent thermal overstress during operation.

Selection Notes

Select this component for applications requiring a precise 51 V reference point with high power handling capabilities up to 5 Watts. Consider the DO-201AE axial package for through-hole mounting solutions where robust mechanical stability is required. Evaluate the thermal derating curve for environments exceeding 75°C ambient temperature to ensure reliable operation within the specified junction temperature limits.

Part Context

This part belongs to the 1N5338B series of silicon Zener diodes produced by Panjit International Inc., a global IDM specializing in discrete semiconductors. The series covers a wide voltage range from 5.1 V to 51 V, offering standardized electrical characteristics across multiple voltage options. The 1N5369B variant specifically targets higher voltage regulation needs within this industrial-grade portfolio.

Replacement Considerations

Cross-reference with other manufacturers' 1N5369 equivalents such as those from onsemi (e.g., 1N5369BG) to verify pinout compatibility and electrical parameter alignment. Ensure that any substitute component meets the same DO-201AE package dimensions and thermal dissipation requirements.
