Overview
The Diotec Semiconductor 1N5378B is a glass passivated junction silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 100 V with a standard tolerance of ±5%. The device operates within a junction temperature range of -50°C to +150°C and dissipates up to 5 W at 50°C ambient temperature. Key electrical characteristics include a test current of 12 mA, a dynamic resistance of 90 Ohms, and a maximum reverse leakage current of 0.5 µA at 76 V. It utilizes the DO-201 axial leaded package.
Feature Summary
- High power dissipation capability of 5 W
- Glass passivated junction construction
- Compliant with RoHS directives
Applications
- Voltage stabilization circuits
- Voltage regulators
- Overvoltage protection (uni-directional)
Procurement Notes
Verify that the ordered component matches the specific Diotec Semiconductor manufacturer designation. Confirm compliance requirements such as REACH and conflict minerals status against project specifications. Ensure the package type corresponds to the required through-hole mounting configuration on the printed circuit board.
Selection Notes
Select this component when a stable 100 V reference point is required in high-power environments. Evaluate thermal management strategies to maintain junction temperatures below 150°C during continuous operation. Consider the dynamic impedance value for applications requiring precise voltage stability under varying load currents.
Part Context
This part belongs to the 1N5345B through 1N5388B series of non-planar technology Zener diodes. The series covers a wide voltage range from 8.7 V to 200 V, all sharing the same 5 W power rating and DO-201 mechanical housing. This specific model provides the mid-range voltage option within the lineup.
Replacement Considerations
Cross-referencing requires matching the 100 V nominal voltage, 5 W power rating, and DO-201 package. Verify that alternative manufacturers provide equivalent dynamic resistance and leakage current specifications to ensure circuit performance parity.
