1N5350B-AP

Overview

The 1N5350B-AP is a silicon unidirectional voltage regulator diode manufactured by MCC. It features a nominal Zener voltage of 13 V with a tolerance of ±5% and a maximum power dissipation of 5 W. The device operates in the through-hole DO-15 (DO-204AC) axial package. Key electrical specifications include a reverse leakage current of 1 µA at 9.9 V, a forward voltage of 1.2 V at 1 A, and a maximum Zener impedance of 2.5 Ohms. The component supports an operating temperature range from -55°C to 150°C.

Feature Summary

• Provides stable voltage regulation using single silicon Zener element technology
• Designed for high-power dissipation applications up to 5 watts
• Features isolated case connection for mounting flexibility

Applications

• Voltage regulation circuits
• Surplus voltage protection
• Reference voltage generation

Procurement Notes

Verify the specific suffix 'AP' against the manufacturer's official documentation to confirm it denotes the same electrical characteristics as the standard 1N5350B-TP variant. Ensure the DO-15 axial leaded package matches the target PCB footprint requirements. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a 13 V reference with 5 W power handling is required in a through-hole configuration. The DO-15 package offers robust mechanical stability compared to smaller surface-mount alternatives. Consider the ±5% tolerance for precision requirements and verify thermal management capabilities for continuous 5 W operation within the specified temperature range.

Part Context

This part belongs to the 1N5350 series of 5 Watt Surmetic 40 Zener Voltage Regulators. The series is widely used in industrial and consumer electronics for power supply stabilization. MCC produces this component under the Micro Commercial Components brand, adhering to standard JEDEC outlines for the DO-15 axial package.

Replacement Considerations

Cross-reference with ON Semiconductor 1N5350B or Diodes Incorporated 1N5350B for pin-compatible substitutes. Verify that alternative manufacturers specify identical 13 V Zener voltage, 5 W power rating, and DO-15 package dimensions to ensure direct interchangeability without circuit modification.
