1N5381BRLG

Overview

The onsemi 1N5381BRLG is a single-channel Zener voltage regulator diode from the 1N53 Series. It features a nominal Zener voltage of 130 V with a ±5% tolerance, operating within a range of 123.5 V to 136.5 V at a test current (IZT) of 10 mA. The device supports a maximum steady-state power dissipation of 5 W and operates across an extended temperature range of -65°C to +200°C. It utilizes a DO-41 axial lead package (CASE 017AA) for through-hole mounting.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior electrical characteristics and tight parameter limits.
• Features robust surge handling capabilities rated up to 180 W for 8.3 ms pulses.
• Provides high electrostatic discharge protection exceeding 16 kV per the Human Body Model.
• Constructed in a void-free, transfer-molded plastic package resistant to corrosion.

Applications

• Voltage regulation in high-power DC circuits
• Surge suppression and transient voltage clamping
• Reference voltage sources in industrial equipment

Procurement Notes

Verify that the ordering suffix 'BRLG' corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm that the component meets Pb-Free standards if environmental compliance is mandatory for the target application. Ensure the procurement documentation explicitly references the 1N53 Series datasheet to validate the electrical parameters against the manufacturer's specifications.

Selection Notes

Select this component when a stable 130 V reference is required in high-voltage environments. The 5 W power rating allows for significant current handling compared to lower-wattage alternatives. Verify that the circuit design accommodates the thermal resistance characteristics and that the operating temperature remains within the specified -65°C to +200°C range to ensure long-term reliability.

Part Context

This part belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators manufactured by onsemi. The series covers a broad voltage spectrum from 3.3 V to 200 V, offering consistent performance across various industrial applications. The 1N5381B variant specifically targets the 130 V segment of this lineup.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N5381B devices or equivalent 5 W, 130 V Zener diodes in the DO-41 package. Ensure any replacement maintains the same ±5% voltage tolerance and thermal characteristics to preserve circuit integrity.
