Overview
The Microsemi Corporation 1N5388E3/TR8 is a silicon 5.0-watt Zener diode with a nominal voltage of 200 V and a tolerance of ±20%. It features a T-18 axial leaded package and operates within a temperature range of -65°C to +150°C. The device has a maximum dynamic impedance of 480 Ohms, a reverse leakage current of 500 nA at 144 V, and a forward voltage of 1.2 V at 1 A.
Feature Summary
- Provides voltage regulation across broad operating current and temperature ranges
- Withstands high surge stresses and offers flexible axial-lead mounting terminals
- Features minimal changes in voltage versus current as specified by voltage regulation
- Moisture classification is Level 1 per IPC/JEDEC J-STD-020B with no dry pack required
Applications
- Voltage regulation in power supply circuits
- High DC current applications requiring adequate heat sinking
- Surge stress protection in electronic systems
Procurement Notes
Verify the component status before procurement, as this part may be discontinued or subject to change. Confirm that the RoHS compliant e3 suffix matches environmental requirements. Ensure the TR8 tape and reel packaging aligns with automated assembly needs. Cross-reference the specific JEDEC registration data for electrical characteristics.
Selection Notes
Select this component when a 200 V Zener voltage with ±20% tolerance is required. Consider the 5 W power dissipation capability and the T-18 through-hole package for mechanical integration. Evaluate thermal resistance requirements for junction-to-lead and junction-to-ambient conditions during circuit design.
Part Context
This part belongs to the JEDEC registered 1N5333B through 1N5388B series of axial-leaded 5.0 watt Zener diodes. The series provides a wide selection of voltages from 3.3 V to 200 V. The e3 suffix indicates RoHS compliance, while the TR8 suffix denotes tape and reel packaging.
Replacement Considerations
Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B series. Other tolerances can be selected using different suffix letters such as B for ±5%, A for ±10%, C for ±2%, or D for ±1%.
