1N5350B-TP

Overview

The 1N5350B-TP is a 5-watt single Zener diode manufactured by Micro Commercial Components (MCC) in the DO-15 axial leaded package. It provides a nominal Zener voltage of 13 V with a ±5% tolerance. The device operates within a junction temperature range of -55°C to +200°C and features a maximum dynamic impedance of 2.5 Ohms at a test current of 100 mA. Electrical characteristics include a maximum reverse leakage current of 1 µA at 9.9 V, a maximum forward voltage of 1.2 V at 1 A, and a maximum surge current capability of 7 A.

Feature Summary

• Provides stable voltage regulation for circuits requiring a 13 V reference point.
• Utilizes a plastic encapsulated DO-15 case rated for high power dissipation up to 5 W.
• Features low thermal resistance design suitable for operation under high DC currents.

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement equipment

Procurement Notes

Verify that the ordered part number matches the specific MCC designation 1N5350B-TP to ensure correct voltage and tolerance specifications. Confirm compliance requirements such as RoHS status if applicable, noting that halogen-free versions require a specific suffix. Ensure sourcing from authorized distributors to guarantee genuine parts and full traceability according to manufacturer standards.

Selection Notes

Select this component when a 13 V regulated output is required with a 5 W power handling capacity. The DO-15 through-hole package is appropriate for applications needing robust mechanical mounting and heat dissipation. Consider the 2.5 Ohm dynamic impedance for regulation precision needs and verify that the operating environment stays within the specified thermal limits for continuous DC conditions.

Part Context

This component belongs to the 1N5338B through 1N5388B series of JEDEC registered 5.0 watt Zener diodes. The series covers a wide voltage range from 5.1 V to 200 V, offering various tolerance options identified by suffix letters. The 1N5350B-TP specifically addresses the 13 V segment of this standardized lineup, sharing common packaging and thermal characteristics with its siblings.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N5350B equivalents or generic 5W 13V Zener diodes in the DO-15 package. Verify that replacement parts match the 13 V nominal voltage, ±5% tolerance, and 5 W power rating. Ensure the alternative component meets the same thermal and electrical performance criteria for safe integration.

FAQ

What is the maximum operating junction temperature for DC conditions?

The maximum operating junction temperature for DC conditions is 150°C, although it can reach 200°C for pulsed conditions with low duty cycles.

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 and must not exceed the value of 5 watts divided by the actual Zener voltage of the device.
