1N5377B-AP

Overview

The 1N5377B-AP is a 5-watt Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 91 V with a tolerance of ±5%. The device utilizes a glass passivated junction and is housed in a DO-15 axial leaded package. It is designed for voltage regulation applications requiring stable performance under specified power dissipation limits.

Feature Summary

• Glass passivated junction for enhanced reliability
• High surge current capability
• Stable Zener voltage characteristics

Applications

• Voltage regulation circuits
• Power supply protection
• Reference voltage sources

Procurement Notes

Verify the specific suffix AP against the manufacturer's official datasheet to confirm packaging details, as suffixes may indicate variations in tape-and-reel or bulk packaging configurations. Ensure the DO-15 footprint matches your PCB design requirements before finalizing procurement orders.

Selection Notes

Select this component when a 91 V Zener voltage with 5 W power rating is required. Confirm that the ±5% tolerance meets the circuit's precision needs. Verify thermal management capabilities are sufficient for continuous operation at full rated power dissipation.

Part Context

This part belongs to the standard 1N53xx series of 5-watt Zener diodes. It is functionally equivalent to parts from other manufacturers such as onsemi or Motorola, sharing the same JEDEC outline and electrical specifications for cross-reference purposes.

Replacement Considerations

Equivalent parts include 1N5377B from onsemi or Motorola. Verify pinout compatibility and thermal resistance values when substituting with components from different manufacturers.
