Product details

Overview

SS1H10LSH from Taiwan Semiconductor is a 1A, 100V AEC-Q101-qualified Schottky barrier rectifier in SOD-123HE package, featuring 0.80V max forward voltage at 1A/25°C, <1.0µA reverse leakage at 25°C, and 30A peak surge current - deployed in automotive-grade DC-DC converters and industrial SMPS.

For engineers reviewing the SS1H10LSH datasheet, SS1H10LSH pinout, SS1H10LSH application, or SS1H10LSH equivalent, key selection criteria include V_RRM=100V, I_F=1A, ultra-low leakage (<1µA @25°C), thermal resistance R_θJA=72°C/W, and AEC-Q101 qualification for under-hood power conversion.

Technical Context

This single-die Schottky rectifier operates with junction temperatures from –55°C to +150°C and uses matte tin-plated leads compliant with J-STD-002 solderability. Its low-profile SOD-123HE package (height <0.85mm) supports automated placement and meets JESD201 Class 2 whisker resistance.

The device delivers high efficiency via low forward voltage drop and ultra-low reverse leakage, enabling reduced conduction loss in high-frequency switching topologies. It sustains 30A non-repetitive surge current (8.3ms half-sine) and exhibits R_θJL=20°C/W for effective lead-based heat dissipation.

FAQ

What is the maximum junction temperature rating for SS1H10LSH?

The SS1H10LSH has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings table in Version B2209 datasheet. This rating enables operation in under-hood automotive environments and high-ambient industrial settings. Derating begins above 75°C ambient, and thermal design must account for R_θJA=72°C/W. The SS1H10LSH maintains full electrical performance up to its T_J limit without parameter shift or reliability risk.

Is SS1H10LSH AEC-Q101 qualified?

Yes, SS1H10LSH is explicitly AEC-Q101 qualified as stated in the FEATURES section of the official Taiwan Semiconductor datasheet (Version B2209). This qualification covers stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life - confirming suitability for automotive power electronics. The SS1H10LSH shares this qualification across the SS1H4LSH–SS1H20LSH family, and the marking "1H10LS" on the device confirms the 100V variant.

What is the forward voltage of SS1H10LSH at 1A and 25°C?

The SS1H10LSH has a maximum forward voltage (V_F) of 0.80 V at I_F = 1 A and T_J = 25°C, per ELECTRICAL SPECIFICATIONS table in Version B2209. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating. At higher junction temperatures (e.g., 125°C), V_F decreases slightly due to Schottky physics. The SS1H10LSH's V_F is optimized for efficiency in 1A-class DC-DC outputs.

Does SS1H10LSH have a specified reverse leakage current?

Yes, SS1H10LSH specifies reverse current (I_R) ≤ 1.0 µA at V_R = 100 V and T_J = 25°C, and ≤ 0.2 mA at V_R = 100 V and T_J = 125°C. These values are confirmed in the ELECTRICAL SPECIFICATIONS table (Note 2, PW = 30 ms pulse test). Ultra-low I_R makes SS1H10LSH suitable for battery-backed and always-on automotive subsystems where standby power must remain below 10 µW.

What package type does SS1H10LSH use?

SS1H10LSH uses the SOD-123HE package - a low-profile surface-mount outline with height <0.85 mm, matte tin-plated leads, and moisture sensitivity level 1 (per J-STD-020). The package features a cathode band for polarity identification and meets UL 94V-0 flammability rating. Dimensions and land pattern match JEDEC DO-214AC, and the SS1H10LSH marking "1H10LS" appears on the cathode-end face.
