1N4741ATR

Overview

The onsemi 1N4741ATR is a single general-purpose Zener diode with a nominal voltage of 11 V and a tolerance of ±5%. It features a maximum power dissipation of 1 W and operates within a temperature range of -65°C to +200°C. Housed in a DO-41 through-hole package, it has a test current of 8.5 mA, maximum Zener impedance of 40 Ω, and reverse leakage current of 5 μA.

Feature Summary

Provides stable voltage regulation for general electronic applications
Capable of operating at high temperatures up to 200°C
Designed for through-hole mounting in standard DO-41 packages

Applications

Voltage reference circuits
Overvoltage protection
Clipping and clamping applications

Procurement Notes

Verify the specific suffix (ATR) matches the required packaging configuration, as this indicates tape and reel delivery. Confirm that the DO-41 through-hole form factor aligns with the target PCB design. Ensure the 11 V nominal voltage and 1 W power rating meet the circuit requirements before finalizing procurement orders.

Selection Notes

Select this component when an 11 V regulation point is required in a through-hole assembly. The 1 N power rating supports moderate current loads. Verify compatibility with existing board layouts due to the DO-41 footprint dimensions. Consider thermal management if continuous operation near the 1 W limit is expected.

Part Context

This part belongs to the 1N47xxA series of Zener diodes manufactured by onsemi. It is a legacy component often used in established designs requiring reliable voltage regulation. The device is distinct from automotive-grade variants and is intended for general commercial and industrial electronics.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N4741A or 1N4741ATR parts with identical electrical specifications and DO-41 packaging. Verify pinout and physical dimensions match before substitution.
