1N5367BG

Overview

The onsemi 1N5367BG is a silicon-oxide passivated junction Zener voltage regulator diode from the 1N53 Series. It provides a nominal reverse Zener voltage of 43 V with a ±5% tolerance, operating within a range of 40.85 V to 45.15 V at a test current of 30 mA. The device features a maximum steady-state power dissipation of 5 W and operates in an axial lead transfer-molded plastic package (CASE 017AA). It offers high surge capability up to 180 W for 8.3 ms pulses and includes an ESD rating of Class 3 (>16 kV) per the Human Body Model.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior electrical characteristics and environmental protection.
• Features tight limits and guaranteed maximum values across multiple electrical parameters.
• Provides robust transient protection with high surge ratings and significant electrostatic discharge resilience.

Applications

• Voltage regulation over broad operating current and temperature ranges
• Protection against transient overvoltage events
• Reference voltage generation in electronic circuits

Procurement Notes

Verify that the ordering suffix 'G' corresponds to the Pb-Free package configuration as specified by the manufacturer. Confirm the specific packaging format required for production, such as bulk boxes or tape and reel options, to ensure compatibility with assembly equipment. Cross-reference the document number 98AON21393DD to access the most current datasheet revisions and mechanical outline details before finalizing procurement specifications.

Selection Notes

Select this component when a precise 43 V reference is required with standard ±5% tolerance. Ensure the application can accommodate the 5 W power dissipation limit and verify adequate heat sinking if operating near maximum thermal limits. Consider the axial lead form factor for through-hole mounting requirements and confirm that the operating temperature range meets the system's environmental demands.

Part Context

This device belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators. The series covers a wide voltage selection from 3.3 V to 200 V, utilizing JEDEC registered type numbers. These components are designed for applications requiring reliable voltage regulation in harsh environments, offering corrosion-resistant finishes and versatile mounting positions within a durable plastic encapsulation.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N5367B variants, such as those from Microsemi or Panasonic, provided they meet the identical 43 V nominal voltage, 5 W power rating, and DO-201AE/Case 017AA physical dimensions. Verify that any replacement maintains the same ±5% tolerance and electrical characteristics to ensure circuit performance parity.
