1N4757AP-TP

Overview

The MCC 1N4757AP-TP is a silicon planar Zener diode designed for voltage regulation and clipping applications. It features a DO-41 axial leaded package with a power dissipation rating of 1.0 W. The device provides a nominal Zener voltage of 51 V with a standard tolerance of ±5%. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a forward voltage drop of 1.2 V at specified test currents.

Feature Summary

• Provides stable voltage regulation across a broad operating temperature range
• Utilizes silicon planar technology for reliable performance in stabilizing circuits
• Features an isolated case construction suitable for through-hole mounting

Applications

• Voltage reference circuits requiring precise regulation
• Clipping and clamping applications in signal processing
• Power supply protection against overvoltage conditions

Procurement Notes

Verify the specific suffix 'AP' against official Micro Commercial Components documentation to confirm exact screening levels or compliance status, as generic 1N4757A data may not reflect this variant's unique attributes. Confirm availability status directly with authorized distributors, as lifecycle notifications indicate potential discontinuation for related series components.

Selection Notes

Select this component when a 51 V regulation point is required within a 1 W power budget. Ensure the circuit design accommodates the thermal constraints of the DO-41 package. Verify that the ±5% voltage tolerance aligns with the application's precision requirements compared to tighter tolerance alternatives.

Part Context

This part belongs to the widely recognized 1N47xx series of power Zener diodes. The 'TP' suffix typically denotes a specific packaging or testing configuration by MCC. While electrically similar to other manufacturers' 1N4757A devices, verify pinout compatibility and thermal resistance parameters if substituting into existing designs originally specified by other vendors.

Replacement Considerations

Cross-reference with Vishay 1N4757A or Microsemi MV1N4757AP for equivalent electrical specifications. Ensure the replacement maintains the DO-41 form factor and 1 W power rating. Validate that any substitute meets the same ±5% voltage tolerance and leakage current limits.
