1N5380BRL

Overview

The onsemi 1N5380BRL is a single-channel Zener voltage regulator diode from the 1N53 Series, housed in an axial lead DO-15 (Surmetic 40) package. It features a nominal reverse Zener voltage of 120 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at 25°C. The device operates within a junction temperature range of -65°C to +200°C and includes silicon-oxide passivated junctions for environmental protection.

Feature Summary

• Utilizes silicon-oxide passivated junctions for enhanced reliability and environmental protection
• Provides tight electrical limits guaranteed across multiple parameters
• Features high surge current capability rated up to 180 W for 8.3 ms pulses
• Offers ESD protection exceeding 16 kV per the Human Body Model

Applications

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

Procurement Notes

Verify that the ordering suffix 'B' corresponds to the required ±5% tolerance specification. Confirm the 'RL' suffix indicates tape and reel packaging rather than bulk boxes. Ensure the component meets RoHS requirements if applicable to your manufacturing process. Cross-reference the specific part number against the manufacturer's latest datasheet revision to confirm active status and any potential design changes.

Selection Notes

Select this component when a stable 120 V reference or regulation point is required in high-power applications. The 5 W power rating allows for significant current handling compared to lower-wattage alternatives. Consider the thermal resistance characteristics and ambient operating temperatures to ensure the junction temperature remains within safe limits during continuous operation.

Part Context

This device belongs to the 1N53 Series of 5 Watt Zener diodes manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, all sharing the same Surmetic 40 axial lead package. These diodes are designed for robust performance in demanding environments, offering superior characteristics over standard Zener diodes due to their specific junction passivation technology.

Replacement Considerations

Compatible substitutes include other 1N5380 variants such as 1N5380BG or generic equivalents meeting the 120 V, 5 W, ±5% specifications in a DO-15 package. Verify that replacement parts maintain the same thermal resistance and surge current ratings to ensure circuit integrity.
