1N5370B TR

Overview

The Central Semiconductor Corp 1N5370B TR is a silicon unidirectional voltage regulator diode with a nominal Zener voltage of 56 V and a maximum power dissipation of 5 W. It features a standard tolerance of ±5% and operates within a temperature range of -65 °C to +200 °C. The device utilizes an axial leaded T-18 package for through-hole mounting.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Engineered for high maximum DC currents with comparatively low thermal resistance design
• Utilizes plastic encapsulation with Level 1 moisture classification

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection stages
• Reference voltage generation

Procurement Notes

Verify the specific ordering suffix required for plating options, such as PBFREE or TIN/LEAD, when placing orders. Confirm availability status as this component may be subject to discontinuation notices. Request official datasheets and environmental compliance documentation directly from Central Semiconductor Corp before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring a 56 V regulation point with 5 W power handling capabilities. Ensure the circuit design accommodates the specified ±5% voltage tolerance and the operational temperature limits. Verify that the T-18 axial package fits the intended PCB layout constraints.

Part Context

This part belongs to the JEDEC registered 1N5333 to 1N5388B series of 5.0 watt Zener diodes. The series offers a wide selection of voltages ranging from 3.3 V to 200 V. Standard tolerances are identified by specific suffix letters on the part number.

Replacement Considerations

Central Semiconductor lists CZ5370B as the replacement for the 1N5370B.
