1N5356B-AP

Overview

The MCC 1N5356B-AP is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 19 V with a tolerance of 5%. The device is rated for a maximum power dissipation of 5 W and operates within a temperature range of -55 °C to +150 °C. Key electrical parameters include a maximum reverse leakage current of 0.5 µA, a Zener impedance of 3 Ω at the test current of 65 mA, and a maximum DC forward current of 250 mA. The component utilizes an axial leaded DO-15 package.

Feature Summary

• Provides stable voltage regulation across a wide operating temperature range
• Engineered for high thermal stability with low thermal resistance design
• Utilizes plastic encapsulation with moisture classification Level 1

Applications

• Voltage reference circuits
• Overvoltage protection systems
• Power supply regulation

Procurement Notes

Verify the specific suffix AP against official Micro Commercial Components documentation to confirm packaging details and compliance status. Ensure the procurement channel provides valid traceability for the JEDEC registered series. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before finalizing orders.

Selection Notes

Select this component when a 19 V regulation point is required in through-hole designs. The 5 W power rating supports higher current applications compared to standard small-signal diodes. Verify that the circuit can accommodate the specified 3 Ω impedance and 0.5 µA leakage current requirements for the intended precision level.

Part Context

This part belongs to the 1N5333B through 1N5388B series of 5 Watt Zener diodes manufactured by Micro Commercial Components. The series offers a broad selection of voltages from 3.3 to 200 volts.
