Overview
The Microsemi Corporation 1N5378A/TR12 is a silicon Zener diode with a nominal voltage of 100 V and a tolerance of ±10%. It operates in an axial-lead T-18 package, providing a maximum power dissipation of 5.0 watts at 25°C. The device features a reverse current test voltage of 72 V for the A suffix and a maximum dynamic impedance of 90 ohms. It includes a TR suffix indicating tape and reel packaging per EIA-296 standards.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses with minimal changes in voltage versus current
- Flexible axial-lead mounting terminals suitable for various environmental conditions
Applications
- Voltage regulation in electronic circuits
- Protection against voltage spikes and surges
- Reference voltage sources in power supplies
Procurement Notes
Verify the specific suffix configuration to ensure compatibility with required packaging and tolerance specifications. Confirm that the TR suffix aligns with automated assembly needs. Check for RoHS compliance status if environmental regulations apply to the final product design. Ensure thermal management strategies account for the specified power dissipation limits.
Selection Notes
Select this component when a 100 V Zener voltage with ±10% tolerance is required. Consider the 5-watt power rating and axial lead format for through-hole applications. Evaluate thermal resistance requirements based on the intended mounting method and ambient temperature conditions. Compare against other suffixes if tighter voltage tolerances or surface mount options are needed.
Part Context
This part belongs to the 1N5333B thru 1N5388B series of JEDEC registered silicon Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 to 200 volts with various tolerance options identified by suffix letters. These devices are designed for robust performance in demanding environments.
Replacement Considerations
Equivalent parts include the 1N5378B (±5% tolerance) and 1N5378C (±2% tolerance). Surface mount equivalents are available as SMBJ5378CE3. Military screening levels can be obtained by adding MQ, MX, or MV prefixes.
