2N5356 TIN/LEAD

Overview

The Central Semiconductor Corp 2N5356 TIN/LEAD is a silicon Zener diode designed for voltage regulation applications. It features a maximum Zener voltage of 19V with a 5% tolerance and a power dissipation rating of 5W. The device utilizes an axial-lead plastic encapsulation in the T-18 package configuration, suitable for through-hole mounting. It operates within a junction temperature range of -65°C to +175°C and is classified as a single-element unidirectional component.

Feature Summary

• Provides stable voltage regulation across a wide operating temperature range
• Utilizes a robust plastic encapsulated design for moisture resistance
• Capable of handling high DC currents when paired with adequate heat sinking

Applications

• High-power voltage regulation circuits
• Power supply protection stages
• Reference voltage generation in industrial equipment

Procurement Notes

Verify that the specific order includes the leaded variant suffix, as environmental compliance differs from lead-free versions. Confirm the T-18 package dimensions match the target PCB footprint. Ensure thermal management strategies account for the 5W power dissipation capability under continuous operation conditions.

Selection Notes

Select this component when a 19V regulation point is required with significant power handling capabilities. The T-18 package offers higher thermal performance compared to standard glass axial packages. Verify that the circuit design accommodates the physical size and lead spacing associated with this specific plastic encapsulation style.

Part Context

This part belongs to the 1N5333B through 1N5388B series of 5-watt Zener diodes manufactured by Central Semiconductor. The series provides a broad selection of voltage ratings from 3.3V to 200V. These devices are JEDEC registered and offer various tolerance options identified by specific suffix letters on the part number.

Replacement Considerations

Equivalent parts include the 2N5356BKLEADFREE variant from the same manufacturer. Cross-reference with other manufacturers' 5W 19V Zener diodes in the T-18 or similar axial plastic packages, ensuring matching voltage tolerance and thermal characteristics.
