Best Alternatives to HS1D

Package: DO-214AC, SMAYangjie TechnologyDiodes - Rectifiers - SinglePackage: Tape & Reel (TR)Voltage - DC Reverse (Vr) (Max): 200 VCurrent - Average Rectified (Io): 1AVoltage - Forward (Vf) (Max) @ If: 1 V @ 1 ACurrent - Reverse Leakage @ Vr: 5 µA @ 200 V

HS1D is a 200V, 1A fast recovery diode in a DO-214AC (SMA) package, ideal for high-frequency rectification. When searching for alternatives, focus on matching the 50ns reverse recovery time.

AI replacement insight

Electrical riskmedium

Mismatch in reverse recovery time (trr) or forward voltage (Vf) is the main electrical risk.

Package risklow

The DO-214AC (SMA) package is common, ensuring good physical compatibility.

Can it be replaced directly?

Yes, US2D is a potential pin-compatible upgrade. Other parts like US1M are physically compatible but have slower recovery times, posing a risk in high-frequency applications.

Best replacement path

US2D is a strong candidate, offering a higher current rating (2A) while matching voltage, package, and critical 50ns recovery time.

Main risk

The primary risk is using a substitute with a slower reverse recovery time (trr > 50ns), which can cause increased switching losses and potential circuit failure.
