Overview
The Vishay 10TQ045S is a Schottky rectifier in the D2PAK (TO-263AB) surface-mount package. It features a maximum average forward current of 10 A and a maximum repetitive peak reverse voltage of 45 V. The device supports junction temperatures up to 175 °C, with a typical forward voltage drop of 0.49 V at 10 A and 125 °C. Maximum reverse leakage current is rated at 2 mA at 25 °C and 15 mA at 125 °C. Non-repetitive surge current capability reaches 1050 A for a 5 µs sine pulse.
Feature Summary
- Optimized for low reverse leakage current at elevated temperatures using proprietary barrier technology
- Guard ring structure provides enhanced ruggedness and long-term reliability
- High purity, high temperature epoxy encapsulation ensures mechanical strength and moisture resistance
- Qualified for Q101 automotive standards
Applications
- Switching power supplies
- Converters
- Freewheeling diodes
- Reverse battery protection
Procurement Notes
Verify the specific ordering suffix to confirm packaging format, as standard production units are supplied in tubes while TRL and TRR variants indicate tape and reel configurations. Confirm lead-free status if required by RoHS compliance protocols. Ensure thermal management design accounts for the specified junction-to-case thermal resistance when mounting on heatsinks.
Selection Notes
Select this component for applications requiring high-frequency operation and low forward voltage drop. The 175 °C junction temperature rating allows for higher thermal margins compared to standard 150 °C devices. Verify that the 45 V reverse voltage rating aligns with the circuit's peak inverse voltage requirements under all operating conditions.
Part Context
This part belongs to the Vishay High Power Products 10TQ...S Schottky rectifier series. The 'S' suffix specifically denotes the D2PAK surface-mount package variant. Other series members include different voltage ratings such as 35 V and various package options like TO-220.
Replacement Considerations
Compatible substitutes within the same series include the 10TQ035S, which shares identical electrical characteristics except for a reduced maximum DC reverse voltage of 35 V.
FAQ
What is the maximum non-repetitive surge current rating?
The maximum peak one-cycle non-repetitive surge current is 1050 A for a 5 µs sine pulse or 3 µs rectangular pulse.
How does the forward voltage drop vary with temperature?
At 10 A, the forward voltage drop is typically 0.57 V at 25 °C and decreases to 0.49 V at 125 °C.
