1N4745A-TAP

Overview

The Vishay 1N4745A-TAP is a silicon planar power Zener diode in the DO-41 (DO-204AL) axial leaded package. It provides a nominal Zener voltage of 16 V with a standard tolerance of ± 5 %. The device operates at a test current of 15.5 mA and features a maximum reverse leakage current of 5 µA at 12.2 V. Dynamic impedance is specified at 16 Ω, while surge current capability reaches 700 mA. Maximum steady-state power dissipation is rated at 1300 mW, supporting operation within a junction temperature range up to 175 °C.

Feature Summary

• Utilizes silicon planar technology for robust performance in stabilizing and clipping circuits
• Provides precise voltage regulation with a standard ± 5 % Zener voltage tolerance
• Engineered for high power rating applications requiring reliable thermal equilibrium

Applications

• Voltage stabilization
• Clipping circuits

Procurement Notes

Verify that the specific ordering code matches the required tape format. Confirm compliance requirements against the manufacturer's material categorization documentation. Ensure design parameters align with absolute maximum ratings before integration into final assemblies.

Selection Notes

Select this component when a 16 V reference point is required in through-hole designs. Evaluate thermal management needs based on the 1300 mW dissipation limit. Verify that the 16 Ω dynamic impedance meets the noise and stability requirements of the target circuit topology.

Part Context

This part belongs to the Vishay 1N4728A to 1N4761A series of Zener diodes. The series covers a broad voltage range from 3.3 V to 75 V. All devices share the same DO-41 package and fundamental planar construction principles defined in document number 85816.

Replacement Considerations

Cross-reference with other manufacturers' 1N4745A specifications. Verify pinout compatibility and ensure equivalent power dissipation ratings are maintained during substitution.

FAQ

What is the maximum surge current rating?

The maximum surge current is 700 mA.

Does the TAP suffix indicate a different electrical function?

No, the TAP suffix indicates packaging in an ammo pack; it does not change the electrical characteristics.
