Overview
The Central Semiconductor Corp 1N5356B BK is a silicon Zener diode with a nominal breakdown voltage of 19V and a tolerance of 5%. It features a 5W power dissipation rating and operates within a temperature range of -65°C to +200°C. The device utilizes an axial-lead T-18 plastic package with two pins. It is designed for high maximum DC currents with adequate heat sinking, offering low thermal resistance.
Feature Summary
- Provides stable voltage regulation across a wide operating temperature range
- Features a robust plastic encapsulation suitable for high-power applications
- Designed for operation at high maximum DC currents with low thermal resistance
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement equipment
Procurement Notes
Verify the specific ordering suffix required for plating options when placing orders. The 'BK' designation indicates bulk packaging. Confirm lead availability as this component may be subject to discontinuation notices or limited stock levels due to its age. Ensure compatibility with existing thermal management solutions given the 5W power rating.
Selection Notes
Select this component for applications requiring a 19V Zener reference with significant power handling capabilities. Consider the T-18 package size for board space constraints. Evaluate thermal requirements carefully, as the device relies on adequate heat sinking for optimal performance at maximum current ratings. Verify that the 5% voltage tolerance meets the precision requirements of the target circuit design.
Part Context
This part belongs to the 1N5333B through 1N5388B series of JEDEC registered axial-leaded 5.0 watt Zener diodes. The series provides voltage regulation from 3.3 to 200 volts. The 'B' suffix typically denotes a 5% tolerance. These devices are plastic encapsulated and classified as Level 1 moisture sensitivity, requiring no dry pack storage.
Replacement Considerations
According to official End of Life notifications, the 1N5356B has been transitioned to End of Life status. The recommended replacement part number is CZ5356B.
