Taiwan Semiconductor Corporation SRAS830

Overview

SRAS830 from Taiwan Semiconductor is a single-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 30 V repetitive peak reverse voltage (V_RRM), 8 A average forward current (I_F), and 150 A non-repetitive surge current (I_FSM). It delivers low forward voltage drop (0.55 V at 8 A, 25°C) and supports high-efficiency switching mode power supplies.

For engineers reviewing the SRAS830 datasheet, SRAS830 pinout, SRAS830 application, or SRAS830 equivalent, key selection factors include its 30 V V_RRM, 0.55 V V_F at full load, 10,000 V/µs dv/dt rating, junction-to-case thermal resistance of 3 °C/W, and RoHS/halogen-free compliance for industrial power conversion designs.

Technical Context

The SRAS830 operates as a unidirectional surface-mount power rectifier optimized for high-frequency switching applications. Its Schottky architecture enables fast recovery with no minority-carrier storage delay, while the integrated guard ring enhances ruggedness against transient overvoltage events.

Thermally, it features a low R_θJC of 3 °C/W and supports continuous operation up to 150°C junction temperature. The device is rated for 150 A surge current (8.3 ms half-sine) and exhibits ≤100 µA reverse leakage at 25°C and rated V_R.

FAQ

What is the maximum junction temperature rating for the SRAS830?

The SRAS830 has a maximum junction temperature (T_J) rating of 150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version K2103). This allows uninterrupted operation in high-ambient environments such as enclosed industrial power supplies where thermal headroom is constrained. The SRAS830 maintains full 8 A I_F capability up to case temperatures of 110°C, supported by its 3 °C/W R_θJC.

Does the SRAS830 have a guard ring structure, and what benefit does it provide?

Yes, the SRAS830 incorporates a guard ring structure explicitly stated in its features list. This design element improves edge termination robustness, enhancing the device's ability to withstand transient overvoltage conditions without premature breakdown. In practical terms, the guard ring increases reliability during line surges and inductive switching events-critical for SMPS and adapter applications where the SRAS830 serves as the main output rectifier.

Is the SRAS830 halogen-free and RoHS compliant?

Yes, the SRAS830 is both RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as confirmed in the "Features" section of the official Taiwan Semiconductor documentation. These certifications are integral to the device's qualification for green electronics manufacturing and are verified through material declarations and third-party testing-not derived from family-level assumptions. The SRAS830 meets these standards out-of-the-box with no additional qualification required.

What is the forward voltage drop of the SRAS830 at rated current and temperature?

The SRAS830 exhibits a typical forward voltage (V_F) of 0.55 V at 8 A forward current and 25°C junction temperature, as specified in the Electrical Specifications table under "Forward voltage(1)". This value is measured using a 0.3 ms pulse test and represents the conduction loss under nominal operating conditions. At elevated temperatures (e.g., 100°C), V_F decreases slightly due to Schottky physics, maintaining low-loss performance across its operational range.

What packaging and reel quantity is available for the SRAS830?

The SRAS830 is supplied in TO-263AB (D2PAK) package on tape-and-reel format, with 800 units per reel, as documented in the Ordering Information section of the Taiwan Semiconductor datasheet. The device marking code is "SRAS830", and the reel conforms to EIA-481 standards. No alternate packaging (e.g., tube or tray) is listed for this part number in official sources.
