1N5368B

Overview

The Diotec Semiconductor 1N5368B is a non-planar silicon Zener diode designed for voltage stabilization and regulation. It features a DO-201 axial leaded package with a maximum power dissipation of 5 W at 50°C ambient temperature. The nominal Zener voltage is 47 V, graded to the E24 standard with a tolerance of ±5%. Key electrical characteristics include a test current of 25 mA, a dynamic resistance of 25 Ohms at the test current, and a reverse leakage current of 0.5 µA at 210 V. The device supports an operating junction temperature range from -50°C to +150°C and can withstand a non-repetitive peak surge power of 80 W.

Feature Summary

• High power dissipation capability up to 5 W in a robust DO-201 plastic case.
• Low reverse leakage current typical of non-planar technology for stable regulation.
• Compliant with RoHS directives (excluding exemption 7a-I) and REACH regulations.

Applications

• Voltage stabilization circuits
• Linear voltage regulators
• Overvoltage protection

Procurement Notes

Verify that the ordered component matches the specific Diotec Semiconductor manufacturer designation. Confirm compliance requirements such as RoHS status and AEC-Q101 qualification if applicable, noting that standard versions differ from automotive grades. Ensure the package type corresponds to the required through-hole mounting configuration on the target PCB layout.

Selection Notes

Select this component when a 47 V reference or clamp is required with moderate power handling capabilities. The DO-201 package provides sufficient thermal mass for continuous operation without excessive heatsinking. Consider the dynamic impedance and leakage specifications to ensure they meet the precision requirements of the specific circuit design under expected operating temperatures.

Part Context

This part belongs to the 1N5345B through 1N5388B series of 5 W Zener diodes manufactured by Diotec Semiconductor. The series utilizes non-planar technology and covers a wide voltage range from 8.7 V to 200 V. All devices in this family share the same mechanical dimensions and general thermal characteristics while differing in their specific Zener voltage ratings and associated test currents.

Replacement Considerations

Cross-reference with other manufacturers' 1N5368B equivalents ensuring identical 47 V Zener voltage, 5 W power rating, and DO-201 package compatibility. Verify that alternative parts meet the same ±5% tolerance and thermal performance standards.
