1N5382B

Overview

The Diotec Semiconductor 1N5382B is a non-planar Zener diode housed in the DO-201 axial through-hole package. It provides a nominal Zener voltage of 140 V with a standard tolerance of ±5%. The device supports a maximum power dissipation of 5 W at 50°C and withstands peak surge currents up to 1500 mA for short pulses. Operating characteristics include a dynamic resistance of 230 Ohms and a reverse leakage current of 500 nA at 106 V. The junction temperature range spans from -50°C to +150°C, ensuring reliable performance in commercial and industrial environments.

Feature Summary

• High power dissipation capability of 5 W for robust thermal management
• Non-planar technology construction for stable voltage regulation
• Compliant with RoHS directives and REACH regulations

Applications

• Voltage stabilization circuits
• Linear voltage regulators
• Overvoltage protection stages

Procurement Notes

Verify that the component matches the specific 140 V rating and DO-201 package dimensions required by the design. Confirm compliance with environmental standards such as RoHS and REACH if mandated by project specifications. Ensure the ordering suffix corresponds to the desired packaging format, typically ammo pack, before finalizing procurement orders.

Selection Notes

Select this component when a high-voltage Zener reference near 140 V is needed within a through-hole assembly. The 5 W power rating allows for significant current handling compared to lower-power variants. Verify that the circuit design accommodates the specified dynamic resistance and leakage current parameters to maintain accurate regulation under expected load conditions.

Part Context

This part belongs to the 1N5345B through 1N5388B series of 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 DO-201 mechanical outline and 5 W power dissipation rating, differing primarily in their specific breakdown voltage and associated test currents.

Replacement Considerations

Cross-reference with other manufacturers offering 140 V, 5 W Zener diodes in the DO-201 package. Verify that substitute parts meet or exceed the 230 Ohm dynamic resistance and 500 nA leakage current limits. Ensure the replacement maintains the same thermal resistance characteristics for equivalent heat dissipation performance.
