Taiwan Semiconductor Corporation SRT16

Overview

SRT16 from Taiwan Semiconductor is a 1 A, 90 V repetitive peak reverse voltage Schottky barrier rectifier in TS-1 package, featuring 0.70 V forward voltage at 1 A and 25 A surge current capability, used in DC-DC converters and AC-DC adapters for high-efficiency power conversion.

For engineers reviewing the SRT16 datasheet, SRT16 pinout, SRT16 application, or SRT16 equivalent, key selection criteria include its 90 V V_RRM, 5 mA reverse leakage at 100 °C, 80 pF junction capacitance at 4 V, TS-1 thermal resistance of 50 °C/W, and AEC-Q101 qualification option (SRT16H).

Technical Context

The SRT16 operates as a single-die Schottky rectifier with guard ring overvoltage protection and pure tin-plated leads compliant with J-STD-002 solderability. Its junction temperature range spans –55 °C to +150 °C, supporting automotive-grade thermal cycling.

Designed for low-loss switching applications, it delivers 0.70 V forward drop at 1 A and 25 A non-repetitive surge current under 8.3 ms half-sine wave conditions, with reverse leakage limited to 500 µA at 25 °C and 5 mA at 100 °C.

FAQ

What is the maximum junction temperature rating for the SRT16?

The SRT16 has a maximum junction temperature (T_J) rating of +150 °C, validated across its full operating range from –55 °C to +150 °C. This rating applies to all SRT16 variants including standard and AEC-Q101-qualified (SRT16H) versions, enabling use in under-hood automotive and high-ambient industrial environments where thermal management is critical. The SRT16 datasheet confirms this limit in the Absolute Maximum Ratings table.

Is the SRT16 pin-compatible with other parts in the SRT12–SRT115 series?

Yes, the SRT16 shares identical TS-1 package dimensions, anode/cathode terminal layout, and polarity marking (cathode band) with all members of the SRT12–SRT115 series. This uniformity allows direct substitution within the same voltage grade group-e.g., SRT15 (60 V) and SRT16 (90 V)-without PCB changes, provided thermal and electrical design margins accommodate the specific V_RRM and V_F values of the selected variant. The SRT16 mechanical drawings confirm identical TS-1 outline.

Does the SRT16 meet automotive reliability standards?

The base SRT16 is not AEC-Q101 qualified; however, the SRT16H variant is explicitly certified to AEC-Q101. The "H" suffix denotes full qualification-including HTOL, TC, UHAST, and ESD testing-for use in automotive powertrain and body electronics. Designers requiring automotive-grade assurance must specify SRT16H, not SRT16, as the qualification is process- and lot-specific, not inherent to the base part number. This distinction is documented in TSC's Ordering Information table.

What is the reverse leakage current specification for the SRT16 at elevated temperature?

The SRT16 specifies 5 mA maximum reverse leakage current (I_R) at rated V_RRM = 90 V and junction temperature of 100 °C. At 25 °C, leakage is limited to 500 µA. These values are measured under standardized pulse conditions (30 ms pulse width) and reflect real-world behavior in thermally stressed power supplies. The SRT16 Electrical Specifications table on page 2 of the I2104 datasheet lists these exact figures for SRT15–SRT16.

How does the SRT16's junction capacitance affect high-frequency switching performance?

The SRT16 exhibits 80 pF typical junction capacitance (C_J) at 1 MHz and 4 V reverse bias, which directly influences switching loss and EMI in high-frequency SMPS designs above 100 kHz. Lower C_J reduces capacitive turn-off current and dv/dt-induced noise versus higher-capacitance alternatives like the SRT115 (28 pF) or SRT12 (110 pF). This makes the SRT16 well-suited for GaN-based adapters and compact DC-DC converters where fast transitions and low EMI are critical. The value is confirmed in the Electrical Specifications table.
