Overview
The Microsemi Corporation 1N5388BE3/TR13 is a silicon 5.0-watt Zener diode with a nominal voltage of 200V and ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum dynamic impedance of 480 ohms at a test current of 5.0 mA. The device has a maximum reverse leakage current of 0.5 µA at 144V and withstands a surge current of 1850 mA. Packaged in an axial T-18 case with RoHS-compliant e3 plating, it is supplied in tape and reel format.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and features minimal changes in voltage versus current
- Utilizes a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
- Offers flexible axial-lead mounting terminals for through-hole applications
Applications
- Voltage regulation over broad operating current and temperature ranges
- High reliability electronic circuits requiring robust thermal performance
- Power supply protection against transient voltage spikes
Procurement Notes
Verify the component matches the exact JEDEC registered part number 1N5388BE3/TR13. Confirm the presence of the 'e3' suffix indicating RoHS compliance and the 'TR' suffix confirming tape and reel packaging. Ensure the manufacturer is identified as Microsemi Corporation or its successor entity, Microchip, to guarantee authenticity and correct electrical specifications.
Selection Notes
Select this component when a 200V Zener voltage with tight ±5% tolerance is required. It is suitable for applications needing 5W power dissipation capability and operation up to +150°C. Consider the axial T-18 package for through-hole mounting and verify that the 480 ohm dynamic impedance meets circuit sensitivity requirements.
Part Context
This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers voltages from 3.3V to 200V with various tolerance options. The 1N5388B specifically denotes the 200V variant with ±5% tolerance, while the 'e3' suffix indicates lead-free construction compliant with environmental directives.
Replacement Considerations
Surface mount equivalents are available as SMBJ5388B or SMBG5388B. For military screening levels, consider parts prefixed with MQ, MX, or MV. Verify that any substitute maintains the 5W power rating and 200V breakdown voltage.
FAQ
What does the 'B' suffix indicate on the 1N5388BE3/TR13?
The 'B' suffix identifies the device as having a standard voltage tolerance of plus or minus 5%.
Is the 1N5388BE3/TR13 sensitive to electrostatic discharge?
No, the device is nonsensitive to ESD per MIL-STD-750 Method 1020.
