Overview
The onsemi 1N4742CRL is a single silicon Zener diode with a nominal voltage of 12 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. The device utilizes a DO-41 axial lead package, has a maximum reverse leakage current of 5 µA, and a Zener impedance of 9 Ω at a test current of 21 mA.
Feature Summary
- Hermetically sealed glass body construction for environmental protection
- Flexible axial-lead mounting terminals for through-hole installation
- Voltage stabilization over a broad operating current and temperature range
Applications
- Voltage regulation in power supply circuits
- Voltage reference applications requiring stable potential
- Transient voltage suppression for circuit protection
Procurement Notes
Verify the specific suffix 'CRL' against the manufacturer's official datasheet to confirm packaging details and exact electrical tolerances. Ensure the component meets RoHS and REACH compliance requirements for your target market. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component when a 12 V regulation point is required with high thermal stability up to 200 °C. The DO-41 package suits through-hole designs needing robust mechanical mounting. Consider the 1 W power rating and 9 Ω impedance for load regulation needs. Verify that the 5% voltage tolerance aligns with the circuit's precision requirements.
Part Context
This part belongs to the 1N47xx series of 1 Watt Zener diodes manufactured by onsemi. The series offers extensive voltage selection from 3.3 V to 30 V. These diodes are designed for general-purpose voltage regulation and transient suppression tasks in industrial and commercial electronics.
Replacement Considerations
Compatible substitutes include the 1N4742A and 1N4742ATR from onsemi, which share identical electrical specifications and DO-41 packaging. Other manufacturers producing standard 1N4742 variants may also serve as functional replacements if pinout and ratings match.
