Overview
The Microsemi Corporation 1N5378BE3/TR13 is a silicon 5.0-watt Zener voltage regulator diode from the JEDEC registered 1N5333B to 1N5388B series. It provides a nominal Zener voltage of 100 V with a standard tolerance of ±5%, indicated by the 'B' suffix. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. This RoHS-compliant component (e3 suffix) is supplied in tape and reel packaging (TR suffix).
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range.
- Features flexible axial-lead mounting terminals for secure installation.
- Withstands high surge stresses and exhibits minimal changes in voltage versus current.
- Complies with RoHS standards and requires no dry pack due to Level 1 moisture classification.
Applications
- Voltage regulation in power supply circuits
- Protection against overvoltage transients
- Reference voltage generation in electronic systems
Procurement Notes
Verify that the part number includes the e3 suffix to confirm RoHS compliance and the TR suffix to ensure tape and reel packaging. Confirm the B suffix indicates the required ±5% voltage tolerance. Ensure the manufacturer is identified as Microsemi Corporation or its authorized successor entity, such as Microchip Technology, to guarantee authenticity and traceability.
Selection Notes
Select this component when a 100 V Zener voltage with ±5% tolerance is required in an axial lead package. Consider the 5-watt power dissipation rating and thermal resistance characteristics for heat sinking requirements. Verify compatibility with the T-18 package dimensions and the specific electrical parameters defined in the datasheet for the 1N5378B series.
Part Context
This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages ranging from 3.3 V to 200 V. These devices are designed for applications requiring robust voltage regulation and high surge current handling capabilities in a plastic encapsulated axial lead format.
Replacement Considerations
Surface mount equivalents are available as SMBJ5378B or SMBG5378B. Other manufacturers produce similar 5-watt Zener diodes, but verification of pinout, voltage tolerance, and thermal characteristics is necessary for direct substitution.
FAQ
What does the 'B' suffix indicate in the part number?
The 'B' suffix designates a standard voltage tolerance of plus or minus 5%.
Is the 1N5378BE3/TR13 sensitive to electrostatic discharge?
No, these plastic encapsulated Zeners are nonsensitive to ESD per MIL-STD-750 Method 1020.
What is the maximum power dissipation at 25°C?
The maximum power dissipation is 5.0 watts at 25°C.
