Taiwan Semiconductor Corporation SD101AW RHG

Overview

SD101AW RHG from Taiwan Semiconductor is a surface-mount switching Schottky barrier diode in SOD-123 package, rated for 60 V peak repetitive reverse voltage, 15 mA forward current, and 0.41 V forward voltage drop at 15 mA - used in low-loss DC-DC converter output rectification and portable power management circuits.

For engineers reviewing the SD101AW RHG datasheet, SD101AW RHG pinout, SD101AW RHG application, or SD101AW RHG equivalent, key selection criteria include its negligible reverse recovery time (1.0 ns), low thermal resistance (28 °C/W), halogen-free UL 94 V-0 molding compound, and guaranteed high-temperature soldering (260°C/10s).

Technical Context

This Schottky diode operates with metal–semiconductor junction architecture to eliminate minority-carrier storage delay, enabling ultrafast switching with trr = 1.0 ns under IF = IR = 5 mA, Irr = 0.1 × IR, RL = 100 Ω test conditions. Its guard ring construction enhances transient robustness without compromising low VF.

The device exhibits VRRM = 60 V, VRWM = 50 V, and VR(RMS) = 42 V, with junction capacitance of 2.1 pF at VR = 0 V, f = 1 MHz - optimized for high-frequency (>1 MHz) switching topologies where capacitive loss and reverse conduction must be minimized.

FAQ

What is the maximum reverse voltage rating for SD101AW RHG?

The SD101AW RHG has a peak repetitive reverse voltage (VRRM) rating of 60 V, a working peak reverse voltage (VRWM) of 50 V, and an RMS reverse voltage (VR(RMS)) of 42 V. These ratings define safe blocking operation under continuous and transient reverse bias conditions at TA = 25°C. Derating is required above 25°C per the thermal resistance specification.

Does SD101AW RHG meet RoHS and halogen-free requirements?

Yes, SD101AW RHG complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. Its molding compound also meets UL 94 V-0 flammability rating, and terminals are matte tin plated and lead-free - fully aligned with modern environmental and safety standards for commercial and industrial electronics.

What is the forward voltage drop of SD101AW RHG at 15 mA?

The SD101AW RHG exhibits a forward voltage drop (VF) of 0.41 V at 15 mA forward current and TA = 25°C. This low VF value minimizes conduction losses in power-path applications such as OR-ing, reverse polarity protection, and synchronous rectifier auxiliary paths where efficiency at light-to-moderate loads is critical.

Is SD101AW RHG suitable for high-frequency switching applications?

Yes, SD101AW RHG is optimized for high-frequency switching due to its 1.0 ns reverse recovery time (trr) and 2.1 pF junction capacitance at 0 V. These parameters enable clean turn-off behavior and minimal displacement current in converters operating above 1 MHz - confirmed by typical characteristics curves in the official datasheet version C1601.

What package type does SD101AW RHG use, and what are its key mechanical features?

SD101AW RHG uses the SOD-123 surface-mount plastic package with gull-wing leads, cathode band polarity marking, and dimensions of 3.55–3.85 mm length × 1.40–1.80 mm width × 0.45–0.70 mm height. It supports high-temperature soldering (260°C/10s) and weighs approximately 0.01 g, making it ideal for automated assembly in compact, high-density layouts.
