Overview
The Microchip Technology 1N5369BE3/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 51 volts with a ±5% tolerance, 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. Electrical characteristics include a maximum dynamic impedance of 27 ohms and a maximum reverse current of 0.5 microamperes.
Feature Summary
- Provides stable voltage regulation across broad operating current and temperature ranges
- Withstands high surge stresses and exhibits minimal voltage change versus current
- Features flexible axial-lead mounting terminals for versatile integration
- Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection systems
- Reference voltage generation in electronic instrumentation
Procurement Notes
Verify component authenticity and datasheet revision status prior to procurement. Confirm RoHS compliance requirements align with the e3 suffix designation. Ensure thermal management design accommodates the specified power dissipation limits and derating curves for the intended application environment.
Selection Notes
Select this component for applications requiring precise 51-volt regulation with tight manufacturing tolerances. The B suffix ensures a ±5% voltage accuracy suitable for standard industrial electronics. Consider the T-18 package dimensions and lead configuration for PCB layout compatibility and mechanical stability during assembly processes.
Part Context
This part belongs to the Microsemi (now Microchip Technology) 1N5333B-1N5388B series of 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. The specific model utilizes a plastic encapsulated body with void-free transfer molded thermosetting epoxy meeting UL94V-0 standards, ensuring reliability in various environmental conditions.
Replacement Considerations
Surface mount equivalents are available as SMBJ5369B or SMBG5369B. Verify pinout compatibility and thermal performance when transitioning between axial-lead and surface mount packages.
