Taiwan Semiconductor Corporation SR30100PT C0G

Overview

SR30100PT from Taiwan Semiconductor is a 30A, 100V Schottky barrier rectifier in TO-247AD (TO-3P) package with dual-die configuration, 0.90V max forward voltage at 15A/25°C, 500µA max reverse leakage at rated VR/25°C, and 300A surge capability - used in high-efficiency DC-DC converters and industrial SMPS.

For engineers reviewing the SR30100PT datasheet, SR30100PT pinout, SR30100PT application, or SR30100PT equivalent, key selection factors include its 100V V_RRM, junction-to-case thermal resistance of 1.5°C/W, AEC-Q101 qualification option (SR30100PTH), and compatibility with high-current, low-loss power rectification designs requiring stable thermal performance up to 150°C junction temperature.

Technical Context

This device implements a dual-die Schottky structure optimized for low conduction loss and fast switching, with guard ring protection enabling robust overvoltage tolerance. Its 1.5°C/W R_θJC supports direct heatsink mounting in high-power density layouts.

The SR30100PT operates across -55°C to +150°C junction range and delivers 500µA max reverse current at 100V/25°C, dropping to 10mA at 100°C - critical for thermally demanding adapter and TV power supply applications where leakage-induced efficiency loss must be minimized.

FAQ

What is the maximum junction temperature rating for SR30100PT?

The SR30100PT has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official TSC datasheet (Version H2103). This rating applies across the full operating range and supports reliable operation in enclosed, high-ambient environments such as sealed power supplies and industrial enclosures. The SR30100PT maintains specified electrical parameters up to this limit when thermal design respects the 1.5°C/W R_θJC.

Does SR30100PT have AEC-Q101 qualification?

The base SR30100PT is not AEC-Q101 qualified; however, the variant SR30100PTH is explicitly listed as AEC-Q101 qualified in the ordering information section of the TSC datasheet (Version H2103). The "H" suffix denotes qualification, including stress testing per AEC-Q101 Rev D. For automotive applications, SR30100PTH must be specified - SR30100PT alone does not carry this qualification.

What is the forward voltage specification for SR30100PT at 30A?

The SR30100PT datasheet specifies forward voltage only at I_F = 15A (0.90V max at 25°C); no V_F value is published at 30A. At higher currents, V_F increases nonlinearly due to series resistance and heating. Designers should use the typical forward characteristic curve (Fig.4) and apply thermal derating based on actual case temperature and R_θJC to estimate V_F at 30A in their specific layout.

Is SR30100PT a single or dual diode device?

The SR30100PT is a dual-die Schottky rectifier in a common-cathode TO-247AD package, confirmed by the "Dual dies" entry under KEY PARAMETERS and the two-anode / one-cathode pinout. This configuration allows independent anode routing for dual-output supplies or parallel operation - distinct from single-die devices like MBR30100CT. The SR30100PT's internal structure supports flexible circuit topologies without external paralleling.

What is the reverse leakage current of SR30100PT at 100°C?

At 100°C junction temperature and rated 100V reverse voltage, the SR30100PT exhibits a maximum reverse leakage current (I_R) of 10mA, as specified in the ELECTRICAL SPECIFICATIONS table (Note 2, pulse test PW = 30ms). This value is critical for thermal runaway analysis in high-temperature applications such as enclosed TV power boards or industrial motor drives, where elevated I_R contributes directly to power loss and further heating.
