1N5359B-TP

Overview

The MCC 1N5359B-TP is a 5.0 W Zener diode with a nominal voltage of 24 V and ±5% tolerance, housed in an axial DO-15 package. It operates within a junction temperature range of -55°C to +200°C and features a maximum thermal resistance of 15°C/W from junction to lead. Electrical characteristics include a test current of 50 mA, a maximum dynamic impedance of 3.5 Ω at the test current, and a maximum reverse leakage current of 0.5 µA at 18.2 V. The device supports a maximum regulator current of 198 mA and can withstand a surge current of 4.4 A.

Feature Summary

• Provides stable voltage regulation across a wide operating temperature range.
• Features low thermal resistance for efficient heat dissipation under high power conditions.
• Constructed with epoxy meeting UL 94 V-0 flammability ratings.

Applications

• Voltage regulation circuits
• Power supply protection
• Overvoltage clamping

Procurement Notes

Verify that the component matches the specific JEDEC registered series requirements for your design. Confirm compliance with RoHS standards if applicable, noting that halogen-free versions require a specific suffix. Ensure sourcing is through authorized distributors to guarantee genuine parts and full traceability as per manufacturer guidelines.

Selection Notes

Select this component when a 24 V reference or clamp is required in a through-hole application. Consider the 5 W power rating and thermal management needs, ensuring adequate heat sinking to maintain junction temperatures within limits. Verify that the 3.5 Ω dynamic impedance meets the circuit's regulation precision requirements.

Part Context

This part belongs to the 1N5338B through 1N5388B series of 5 Watt Zener Diodes manufactured by Micro Commercial Components. The series offers a broad selection of voltages ranging from 5.1 V to 200 V, all utilizing the same DO-15 axial leaded plastic encapsulation format.

Replacement Considerations

Cross-reference with other manufacturers' 1N5359 equivalents. Ensure substitute parts match the 24 V nominal voltage, 5 W power dissipation, and DO-15 package dimensions. Verify that the replacement maintains similar electrical parameters such as dynamic impedance and leakage current.

FAQ

What is the maximum surge current capability of the 1N5359B-TP?

The maximum non-recurrent square-wave surge current is 4.4 A with a pulse width of 8.3 ms.

How is the maximum regulator current determined for this device?

The maximum regulator current is based on the maximum voltage of a 5% type unit, calculated as 5 watts divided by the actual Zener voltage.
