Overview
The Vishay 1N4752A-TR is a silicon planar power Zener diode in the DO-41 (DO-204AL) axial through-hole package. It provides a nominal Zener voltage of 33 V with a standard tolerance of ±5%. The device supports a maximum power dissipation of 1.3 W and operates within a junction temperature range up to 175 °C. Electrical characteristics include a test current of 7.5 mA, a maximum dynamic resistance of 45 Ω at IZT1, and a reverse leakage current of 5 µA at 25.1 V. The component is supplied on a 14-inch reel containing 5000 units per roll.
Feature Summary
- Designed for use in stabilizing and clipping circuits requiring high power ratings
- Utilizes silicon planar technology for robust performance
- Features a hermetically sealed glass construction with compression bonded elements
Applications
- Voltage stabilization
- Clipping circuits
Procurement Notes
Verify that the ordering suffix -TR corresponds to the taped reel configuration containing 5000 units per 14-inch reel. Confirm the specific part number matches the required 33 V nominal voltage and ±5% tolerance specifications. Ensure the DO-41 package dimensions align with the target PCB layout requirements.
Selection Notes
Select this component when a 33 V reference or regulation point is needed in a through-hole design. The 1.3 W power rating allows for higher current handling compared to lower-power variants. Verify that the operating ambient temperature does not exceed limits that would require derating the power dissipation below the 1.3 W maximum.
Part Context
This component belongs to the 1N4728A to 1N4761A series of Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of nominal voltages from 3.3 V to 75 V. All devices in this family share the same DO-41 package and general structural features while differing in their specific electrical breakdown parameters.
