89CNQ135ASM

Overview

The Vishay 89CNQ135ASM is a center-tap Schottky rectifier module in the D-61-8-SM package. It features a maximum DC reverse voltage of 135 V and an average forward current of 40 A per leg (80 A total). The device operates with a junction temperature range of -55°C to 175°C. Key electrical characteristics include a typical reverse leakage current of 1.5 mA at 25°C and a maximum forward voltage drop of 0.99 V at 40 A. The module utilizes proprietary barrier technology for low forward voltage drop and high-frequency operation.

Feature Summary

Center tap configuration optimized for low forward voltage drop
Proprietary barrier technology enabling reliable operation up to 175°C junction temperature
High purity, high temperature epoxy encapsulation for mechanical strength and moisture resistance
Guard ring design for enhanced ruggedness and long-term reliability

Applications

Switching power supplies
Converters
Free wheeling diodes
Reverse battery protection

Procurement Notes

Verify component authenticity through authorized channels as this part number may be subject to obsolescence or replacement by newer series variants. Confirm that the specific ordering suffix matches the required lead frame and packaging specifications. Ensure thermal management designs account for the specified junction-to-case thermal resistance values under actual operating conditions.

Selection Notes

Select this component for applications requiring high surge current capability and low forward voltage drop at elevated temperatures. The 135 V rating suits lower voltage DC bus applications. Consider the D-61-8-SM footprint constraints and mounting torque requirements during PCB layout. Evaluate thermal performance against the provided derating curves for continuous duty cycles.

Part Context

This device belongs to the 89CNQ...A Series of Schottky rectifiers manufactured by Vishay General Semiconductor. The series utilizes the New GenIII D-61 Package family, offering a small footprint with high current handling capabilities. The 'ASM' suffix denotes the surface mount variant within the D-61-8-SM case style.
