1N5387BRL

Overview

The onsemi 1N5387BRL is a single-channel Zener voltage regulator from the 1N53 Series, housed in an axial lead DO-15 (Surmetic 40) package. It features a nominal Zener voltage of 190 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 superior operating characteristics and environmental protection
• Provides tight electrical limits guaranteed across multiple parameters including impedance and leakage current
• Features high surge capability rated up to 180 W for 8.3 ms pulses

Applications

• Voltage regulation circuits requiring stable reference voltages
• 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 configuration as specified in the datasheet. Confirm the presence of the 'G' suffix if lead-free compliance is required. Ensure the component matches the Surmetic 40 mechanical outline dimensions before integration into the assembly process.

Selection Notes

Select this component when a precise 190 V regulation point is needed with high power handling capabilities. The 5 W rating allows for significant current flow compared to lower-power alternatives. Consider the thermal resistance characteristics and derating requirements above 25°C to ensure reliable operation under continuous load conditions.

Part Context

This part belongs to the 1N5333B through 1N5388B series of 5 Watt Zener diodes manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, offering various tolerance options identified by specific suffix letters. These devices are designed for applications requiring robust performance in common environmental conditions.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N5387B equivalents or onsemi's 1N5387B without the reel suffix for bulk box procurement. Verify that any replacement maintains the same 5 W power rating, 190 V nominal voltage, and ±5% tolerance to ensure circuit compatibility.
