1N5946BRL

Single Zener Diodes Overview

The onsemi 1N5946BRL is a single-channel Zener voltage regulator diode from the 1N5913B series, housed in an axial-lead DO-41 (Surmetic 30) plastic package. It provides a nominal Zener voltage of 75 V with a ±5% tolerance and a maximum steady-state power dissipation of 3 W at 75°C lead temperature. The device operates within a junction temperature range of -65°C to +200°C and features silicon-oxide passivated junctions for environmental protection.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and environmental protection
• Offers high surge capability rated at 98 W for 1 ms pulses
• Provides robust ESD protection exceeding 16 kV per the Human Body Model
• Guarantees maximum limits on up to six electrical parameters

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference voltages
• Overvoltage protection stages in electronic systems
• Clamping applications for transient suppression

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'RL' corresponds to the Tape & Reel packaging configuration containing 6000 units per reel as specified in the datasheet. Confirm the presence of the 'G' suffix if Pb-Free certification is required for the specific procurement order.

Single Zener Diodes Selection Notes

Select this component when a 75 V regulation point is needed within a 3 W power dissipation envelope. Ensure the application environment remains within the -65°C to +200°C operating range. Verify that the axial-lead DO-41 package dimensions fit the mechanical constraints of the target printed circuit board layout.

Single Zener Diodes Part Context

This part belongs to the 1N5913B series of 3 W Zener diodes 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 1N5946B variant specifically targets the 75 V segment of this broad portfolio.

Single Zener Diodes Replacement Considerations

Compatible replacements include other manufacturers' equivalents meeting the 1N5946B specification, such as the Microchip Technology 1N5946B or the Microsemi 1N5946BPE3/TR8, provided they match the 75 V nominal voltage, 3 W power rating, and DO-41 package outline.
