1N5371BG

Overview

The onsemi 1N5371BG is a silicon-oxide passivated Zener voltage regulator diode with a nominal breakdown voltage of 60 V and a tolerance of ±5%. It operates within a reverse voltage range of 57 V to 63 V at a test current of 20 mA. The device features a maximum steady-state power dissipation of 5 W and a junction-to-lead thermal resistance of 25 °C/W. It utilizes an axial lead Surmetic 40 (CASE 017AA) plastic package, supports a maximum operating temperature of 200 °C, and includes an ESD rating exceeding 16 kV per the Human Body Model.

Feature Summary

• Utilizes silicon-oxide passivated junctions for tight electrical limits and superior operating characteristics
• Encased in a void-free, transfer-molded thermosetting plastic package resistant to common environmental conditions
• Provides high surge capability up to 180 W at 8.3 ms pulse width

Applications

• Voltage regulation circuits requiring stable reference levels
• Protection against transient overvoltage events
• Surge suppression in electronic systems

Procurement Notes

Verify that the ordering suffix 'G' corresponds to the Pb-Free package designation as defined in the datasheet. Confirm the specific part number matches the 1N5371B series requirements. Ensure compliance with RoHS directives if applicable to the target application environment. Cross-reference the manufacturer's documentation for any updates regarding packaging or material composition changes.

Selection Notes

Select this component when a 60 V Zener voltage with ±5% tolerance is required. Ensure the circuit design accommodates the 5 W power dissipation limit and the specified thermal resistance. Verify that the axial lead package fits the board layout constraints. Consider the maximum operating temperature range and the surge current capabilities for transient protection scenarios.

Part Context

This device 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 consistent performance across various breakdown voltages. All devices in this family share similar mechanical characteristics and utilize the same axial lead plastic package for environmental protection.

Replacement Considerations

Compatible replacements include other manufacturers' 1N5371B equivalents that meet the 60 V nominal voltage, 5 W power rating, and ±5% tolerance specifications. Ensure substitute components support the same axial lead package and thermal characteristics.
