1N5388B-AP

Overview

The 1N5388B-AP is a Zener diode manufactured by Micro Commercial Components (MCC). It belongs to the 1N53 series of 5-watt DC power dissipation Zener regulators. The device provides a nominal Zener voltage of 200V with a tolerance of ±5%. It utilizes an epoxy encapsulation that meets UL 94 V-0 flammability ratings and features axial leads for through-hole mounting in a DO-15 package. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Provides stable voltage regulation at 200V with ±5% tolerance
• Features epoxy encapsulation meeting UL 94 V-0 flammability standards
• Supports operation across extended temperatures from -55°C to +150°C

Applications

• Voltage regulation circuits requiring 200V reference
• Overvoltage protection for high-voltage inputs
• General-purpose discrete semiconductor applications

Procurement Notes

Verify the specific suffix against official MCC documentation, as ordering codes may indicate variations in compliance or packaging. Confirm the manufacturer directly with Micro Commercial Components to ensure authenticity and current production status before procurement.

Selection Notes

Select this component when a 200V Zener regulator with 5W power dissipation is required. Ensure the circuit design accommodates the thermal resistance characteristics and that the operating environment remains within the specified -55°C to +150°C range for reliable performance.

Part Context

This part is part of the broader 1N5333B through 1N5388B JEDEC registered series. These devices are silicon planar Zener diodes designed for general-purpose voltage regulation. The series offers a wide selection of voltages from 3.3V to 200V in a robust axial-leaded package suitable for high-power applications.

Replacement Considerations

Cross-reference with other manufacturers' 1N5388B equivalents. Verify pinout compatibility and thermal management requirements when substituting with parts from different suppliers.
