Overview
The MCC 1N5375B-TP is a 5W Zener diode with an 82V nominal voltage and ±5% tolerance. It operates in the DO-15 axial package, supporting a maximum DC power dissipation of 5W at 75°C lead temperature. The device features a maximum dynamic impedance of 65Ω and a reverse leakage current of 0.5µA at 62.2V. It withstands a maximum surge current of 1.8A (8.3ms pulse) and maintains a junction-to-lead thermal resistance of 15°C/W.
Feature Summary
- Glass passivated junction for enhanced stability
- Epoxy casing meeting UL 94 V-0 flammability rating
- Lead-free finish compliant with RoHS directives
Applications
- Voltage regulation circuits
- Overvoltage protection systems
- Reference voltage generation
Procurement Notes
Verify the specific ordering suffix to confirm packaging format, as standard bulk, tape-and-reel, and ammo pack options exist within this product family. Ensure compliance requirements such as halogen-free status are explicitly requested if needed, as they require a distinct suffix addition. Confirm that the component meets the intended environmental operating limits before finalizing procurement specifications.
Selection Notes
Select this component when a stable 82V reference is required in high-power applications up to 5W. Consider the 65Ω dynamic impedance for regulation precision needs. Evaluate the thermal management strategy based on the 15°C/W junction-to-lead resistance to ensure the junction temperature remains within safe operating limits during continuous DC operation.
Part Context
This part belongs to the 1N5338B through 1N5388B series, covering Zener voltages from 5.1V to 200V. All devices in this range share identical mechanical dimensions, power ratings, and general electrical characteristics defined by the manufacturer's datasheet for the DO-15 plastic encapsulated package.
Replacement Considerations
The 1N5375BRLG from onsemi is a confirmed substitute offering equivalent 82V and 5W specifications in a compatible package configuration.
FAQ
What is the maximum non-repetitive surge current for this device?
The maximum surge current is specified as 1.8A for an 8.3ms square-wave pulse.
How is the cathode terminal identified on the component body?
The cathode end is marked with a colored band on the epoxy casing.
