89CNQ135ASL

Overview

The Vishay 89CNQ135ASL is a center-tap Schottky rectifier module in the D-61-8-SL 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, offering low forward voltage drop and high-frequency operation capabilities.

Feature Summary

• Center tap configuration optimized for low forward voltage drop
• Proprietary barrier technology enabling reliable 175°C operation
• High purity 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 the specific ordering suffix 'SL' against the datasheet outline table to confirm the leaded D-61-8-SL package variant. Confirm RoHS compliance status as the source document indicates industrial level qualification without explicit environmental declarations. Ensure mounting torque specifications are met during installation.

Selection Notes

Select this component for applications requiring high surge current handling up to 4300 A and low thermal resistance. Consider the 135 V rating for appropriate reverse voltage margins. Evaluate the D-61-8-SL package dimensions for PCB layout compatibility and verify heatsinking requirements based on the specified thermal resistance values.

Part Context

This part belongs to the 89CNQ...A series of Schottky rectifiers from International Rectifier, now part of Vishay. The series includes variants with different voltage ratings such as 135 V and 150 V. The 'ASL' suffix denotes the specific leaded package style within the GenIII D-61 family.

Replacement Considerations

Cross-reference with other 89CNQ135A variants like 89CNQ135ASM or 89CNQ135A if package differences are acceptable. Verify electrical parameters match exactly when substituting.
