1N4736A

Overview

The onsemi 1N4736A is a single-channel Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 6.8 V with a tolerance of 5%. The device supports a maximum power dissipation of 1 W and operates within a temperature range from -65 °C to +175 °C. Key electrical parameters include a maximum reverse leakage current of 10 µA, a Zener impedance of 3.5 Ohms, and a test current of 37 mA. It utilizes a DO-41-2 through-hole package.

Feature Summary

• Provides stable voltage regulation with a nominal 6.8 V reference point
• Supports high thermal operation up to +175 °C junction temperature
• Utilizes a glass-passivated silicon construction for reliability

Applications

• Voltage reference circuits in precision measurement equipment
• Overvoltage protection stages in power supply inputs
• Biasing networks for transistor amplifier stages

Procurement Notes

Verify the manufacturer origin carefully, as Microchip Technology also produces a part with this designation that may differ in specifications such as maximum operating temperature or compliance status. Confirm the specific datasheet version matches your design requirements before ordering. Check RoHS and REACH SVHC declarations for regulatory compliance in your target market.

Selection Notes

Select this component when a 6.8 V regulation point is required in a through-hole assembly. Ensure the circuit can handle the 1 W power dissipation at the expected ambient temperature. Compare the 3.5 Ohm impedance against other variants if low noise or tight regulation is critical for the application.

Part Context

This component belongs to the standard 1N47xx series of axial leaded Zener diodes. It is widely used in general-purpose electronics for simple voltage clamping and reference tasks. The DO-41 package provides robust mechanical mounting for industrial and consumer applications.
