1N5378BRL

Overview

The onsemi 1N5378BRL is a 5 Watt Zener voltage regulator diode from the 1N53 Series, housed in an axial lead Surmetic 40 package (CASE 017AA). It features a nominal Zener voltage of 100 V with a ±5% tolerance. The device operates within a temperature range of -65°C to +200°C and includes silicon-oxide passivated junctions for superior environmental protection.

Feature Summary

• Utilizes silicon-oxide passivated junctions for enhanced operating characteristics
• Provides surge rating capability up to 180 W at 8.3 ms pulse width
• Features Class 3 ESD protection exceeding 16 kV per Human Body Model

Applications

• Voltage regulation circuits requiring high power dissipation
• Surge protection applications utilizing transient current handling
• General purpose electronic equipment protected by transfer-molded plastic packaging

Procurement Notes

Verify the specific ordering suffix 'RLG' against official documentation to confirm tape and reel packaging specifications. Ensure compliance requirements such as RoHS status are validated through manufacturer compliance documents before procurement.

Selection Notes

Select this component when a 100 V Zener reference with 5 W steady-state power dissipation is required. Consider the axial lead configuration and thermal resistance characteristics for heat sinking strategies in your design.

Part Context

This part belongs to the 1N53 Series of 5 Watt Zener Voltage Regulators manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, offering tight limits and improved performance compared to standard equivalents.

Replacement Considerations

Cross-reference with other manufacturers' 1N5378B variants. Verify that substitute components match the 100 V nominal voltage, 5 W power rating, and DO-15/Case 017AA physical dimensions.
