1N5358B-TP

Overview

The MCC 1N5358B-TP is a 5.0 W silicon Zener diode with a nominal voltage of 22 V and ±5% tolerance. It operates in the DO-15 axial leaded package, supporting junction temperatures from -55°C to +200°C. Key electrical parameters include a maximum dynamic impedance (ZZT) of 3.5 Ω at 50 mA test current, a reverse leakage current of 0.5 µA at 16.7 V, and a maximum forward voltage of 1.2 V at 1 A. The device provides a maximum regulator current of 216 mA and withstands a surge current of 4.7 A.

Feature Summary

• Provides stable voltage regulation within a wide operating temperature range suitable for demanding environments.
• Features low thermal resistance design allowing operation at high DC currents when paired with adequate heat sinking.
• Constructed with epoxy that meets UL 94 V-0 flammability ratings for enhanced safety compliance.

Applications

• Voltage regulation circuits requiring 5 W power dissipation capacity
• Power supply protection against overvoltage conditions
• Reference voltage generation in electronic instrumentation

Procurement Notes

Verify component authenticity by sourcing exclusively from authorized Micro Commercial Components distributors or directly from the manufacturer. Ensure the ordering suffix matches specific requirements, such as adding '-HF' for halogen-free versions. Confirm packaging preferences including tape-and-reel, ammo box, or bulk quantities before finalizing orders.

Selection Notes

Select this component for applications needing precise 22 V regulation with tight ±5% tolerance. Evaluate thermal management strategies carefully, as the maximum regulator current depends on maintaining lead temperatures below 75°C. Consider the dynamic impedance characteristics when designing circuits sensitive to load variations.

Part Context

This part belongs to the 1N5338B through 1N5388B series of 5 Watt Zener Diodes manufactured by Micro Commercial Components. The series covers a broad voltage range from 5.1 V to 200 V, utilizing standardized JEDEC registration for consistent performance across various industrial and commercial electronics designs.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent 5 W, 22 V Zener diodes in the DO-15 package. Verify that substitute parts match the required ±5% tolerance, dynamic impedance limits, and thermal resistance specifications to ensure circuit compatibility.
