Taiwan Semiconductor Corporation SR2030 C0G

Overview

SR2030 from Taiwan Semiconductor is a 20A, 30V AEC-Q101-qualified Schottky barrier rectifier in TO-220AB package, featuring 0.55V forward voltage at 10A/25°C, 200A surge capability, and guard ring overvoltage protection for use in automotive-grade DC-DC converters.

For engineers reviewing the SR2030 datasheet, SR2030 pinout, SR2030 application, or SR2030 equivalent, key selection criteria include repetitive peak reverse voltage (30 V), junction-to-case thermal resistance (1 °C/W), TJ max rating (150 °C), and AEC-Q101 qualification status for under-hood power conversion designs.

Technical Context

The SR2030 integrates dual Schottky die in a single TO-220AB package with common-cathode configuration, enabling high-efficiency unidirectional conduction in high-current switching paths. Its guard ring structure enhances ruggedness against transient overvoltage events typical in automotive load-dump conditions.

Thermal performance is defined by a low R_θJC of 1 °C/W and maximum junction temperature of +150 °C, supporting continuous 20A operation with appropriate heatsinking. Reverse leakage remains ≤500 µA at 25°C and ≤15 mA at 100°C, ensuring stable blocking behavior across industrial temperature ranges.

Key Specifications

Pinout & Package

FAQ

What is the maximum junction temperature rating for SR2030?

The SR2030 has a maximum junction temperature (T_J) rating of +150 °C, verified per AEC-Q101 stress testing. This allows uninterrupted 20A operation at case temperatures up to 75°C with proper heatsinking, making SR2030 suitable for under-hood automotive applications where ambient temperatures exceed 105°C.

Is SR2030 pin-compatible with other devices in the SR20xx family?

Yes, all SR20xx devices-including SR2030-share identical TO-220AB mechanical outline, pin assignment (Anode 1, Anode 2, Cathode tab), and mounting torque specification (0.56 N·m max). Voltage variants (SR2020 to SR20150) are mechanically interchangeable, though electrical parameters such as V_RRM and V_F differ per model.

Does SR2030 require a heatsink in 20A continuous operation?

Yes, SR2030 requires a heatsink for 20A continuous operation. With R_θJC = 1 °C/W and V_F ≈ 0.55V, power dissipation reaches ~11W at full load. To maintain T_J ≤ 150°C at 75°C ambient, a heatsink with R_θCA ≤ 6.8 °C/W is necessary-verified using standard thermal modeling per JEDEC JESD51-2.

What does the "H" suffix mean in SR2030H ordering code?

The "H" suffix in SR2030H denotes AEC-Q101 qualification. SR2030H undergoes full automotive stress testing-including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST)-and is screened to meet zero-defect quality standards for automotive power systems.

How does the guard ring in SR2030 improve system reliability?

The guard ring in SR2030 enhances edge termination robustness, raising the critical dv/dt rating to 10,000 V/µs. This prevents spurious conduction during fast-switching transients in automotive load-dump or inductive kickback events, eliminating risk of shoot-through failure in bridge-configured power stages using SR2030.
