Taiwan Semiconductor Corporation SR2090PTHC0G

Overview

SR2090PTHC0G from Taiwan Semiconductor is a 20A, 90V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.92V forward voltage at 10A/25°C, 200A surge capability, and 1.5°C/W junction-to-case thermal resistance for high-efficiency power conversion in automotive and industrial SMPS.

For engineers reviewing the SR2090PTHC0G datasheet, SR2090PTHC0G pinout, SR2090PTHC0G application, or SR2090PTHC0G equivalent, this device supports high-reliability DC–DC converters, monitor power supplies, and TV mainboard rectification where low conduction loss and robust surge handling are critical.

Technical Context

This dual-die Schottky rectifier operates with a maximum repetitive peak reverse voltage of 90 V and a junction temperature range of –55°C to +150°C. Its low VF (0.92 V typ. @ 10 A, 25°C) and low R_θJC (1.5°C/W) enable efficient thermal management in high-current switching topologies.

The device integrates guard ring overvoltage protection and meets UL 94V-0 flammability requirements. Reverse leakage is limited to 100 µA at 25°C and 5 mA at 125°C, supporting stable operation under elevated ambient conditions.

FAQ

What is the maximum junction temperature rating for SR2090PTHC0G?

The SR2090PTHC0G has a maximum junction temperature (T_J) rating of +150°C, validated per AEC-Q101 stress testing. This allows operation in under-hood automotive environments and high-ambient industrial settings. Derating begins above 125°C per the forward current derating curve in the official datasheet, and thermal design must maintain T_J ≤ 150°C under worst-case load and ambient conditions for SR2090PTHC0G.

Is SR2090PTHC0G pin-compatible with other parts in the SR20xxPT family?

Yes, all SR20xxPT variants-including SR2090PTHC0G-share identical TO-247AD (TO-3P) mechanical outline, pin assignment, and terminal dimensions. The "x" in the part number denotes rated V_RRM (20V to 150V), but package, pinout, and mounting torque (1.13 N·m max) are fully consistent across the family for drop-in replacement within voltage-design margin.

Does SR2090PTHC0G have a common-cathode or common-anode configuration?

SR2090PTHC0G uses a common-cathode configuration with two independent anodes and one shared cathode terminal. This is confirmed by the dual-die marking diagram and electrical specifications showing separate forward voltage measurements per diode. The configuration supports dual-output or interleaved rectifier designs without external paralleling components for SR2090PTHC0G.

What does the "H" and "C0G" suffix indicate in SR2090PTHC0G?

In SR2090PTHC0G, "H" denotes AEC-Q101 qualification per the ordering information table; "C0G" indicates halogen-free molding compound compliant with IEC 61249-2-21. Both suffixes are factory-applied identifiers-"H" reflects full automotive stress testing, and "C0G" certifies absence of brominated flame retardants while retaining UL 94V-0 flammability rating for SR2090PTHC0G.

How does the guard ring feature improve reliability in SR2090PTHC0G?

The guard ring in SR2090PTHC0G is a diffusion-defined structural element that suppresses edge electric field crowding during voltage transients. It prevents localized avalanche initiation at the silicon periphery, thereby increasing the device's effective V_RRM margin and extending lifetime under repetitive line surges-critical for SR2090PTHC0G in automotive 12V/48V systems exposed to load dump events.
