1N5368BRL

Overview

The onsemi 1N5368BRL is a 5 Watt Zener diode from the 1N53 Series, housed in an axial lead Surmetic 40 (DO-15) plastic package. It provides a nominal Zener voltage of 47 V with a ±5% tolerance and a maximum dynamic impedance of 25 Ω at a test current of 25 mA. The device features a maximum reverse leakage current of 0.5 µA at 35.8 V and supports a maximum steady-state power dissipation of 5 W. It operates within a junction temperature range of -65°C to +200°C.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and environmental protection.
• Offers high surge current capability rated up to 180 W for an 8.3 ms pulse width.
• Provides robust electrostatic discharge (ESD) protection exceeding 16 kV per the Human Body Model.

Applications

• Voltage regulation circuits requiring stable DC output levels.
• Overvoltage protection for sensitive electronic components.
• Transient voltage suppression in industrial equipment.

Procurement Notes

Verify that the ordering suffix 'RL' corresponds to the tape and reel packaging format containing 4000 units per reel. Confirm the presence of the 'G' suffix if lead-free compliance is required by the specific application standards. Ensure the component matches the Surmetic 40 mechanical outline dimensions for proper board layout integration.

Selection Notes

Select this component when a 47 V regulation point is required with a 5 W power handling capacity. The axial lead configuration facilitates through-hole mounting. Consider the thermal resistance characteristics and derating requirements above 25°C to ensure the junction temperature remains within safe operating limits during continuous operation.

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, utilizing transfer-molded plastic packages designed for common environmental conditions. The 1N5368B variant specifically targets the 47 V nominal regulation requirement within this extensive lineup.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N5368B devices or equivalent 5W Zener diodes with matching 47V nominal voltage and DO-15 axial lead packages. Verify electrical parameters such as impedance and leakage current against the original datasheet specifications before substitution.
