Overview
The Microsemi Corporation 1N5381BE3/TR8 is a JEDEC registered silicon Zener diode with a nominal voltage of 130 V and a ±5% tolerance. It operates within a power dissipation range up to 5.0 watts at 25°C, utilizing a T-18 axial-lead package. The device withstands operating temperatures from -65°C to +150°C and features RoHS compliance indicated by the e3 suffix.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses without failure
- Features minimal changes in voltage versus current as specified by voltage regulation parameters
- Includes flexible axial-lead mounting terminals for standard through-hole applications
Applications
- Voltage regulation circuits requiring robust thermal performance
- Power supply protection against high surge stresses
- General-purpose voltage reference applications in industrial environments
Procurement Notes
Verify that the component matches the exact part number 1N5381BE3/TR8 to ensure correct voltage tolerance and RoHS compliance status. Confirm the presence of the TR suffix for tape and reel packaging if automated assembly is required. Cross-reference datasheet specifications against your specific circuit requirements before finalizing procurement orders.
Selection Notes
Select this component when a precise 130 V Zener voltage with tight ±5% tolerance is necessary. Ensure adequate heat sinking is provided to maintain operation within the 5-watt power dissipation limit. Verify that the T-18 axial lead package fits the designated PCB layout constraints and mounting style requirements.
Part Context
This device belongs to the 1N5333B through 1N5388B series of 5.0 watt Zener diodes manufactured by Microsemi. The series offers a wide selection of voltages ranging from 3.3 to 200 volts. The e3 suffix denotes RoHS compliant manufacturing, while the TR suffix indicates availability in tape and reel packaging for efficient surface mount or automated insertion processes.
Replacement Considerations
Equivalent parts include MQ1N5381BE3/TR8 and MSP1N5381BE3/TR8 for military screening levels. Surface mount alternatives are available in SMBJ5381B or SMBG5381B packages.
