Taiwan Semiconductor Corporation SR30150PTH

Overview

SR30150PTH from Taiwan Semiconductor is a 30A, 150V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 1.00 V forward voltage at 15 A and 25°C, 500 µA reverse leakage at rated VR and 25°C, and 300 A surge capability. It serves as a high-efficiency output rectifier in automotive-grade DC/DC converters and industrial SMPS.

For engineers reviewing the SR30150PTH datasheet, SR30150PTH pinout, SR30150PTH application, or SR30150PTH equivalent, key selection criteria include its 150 V repetitive peak reverse voltage, dual-die construction, junction-to-case thermal resistance of 1.5 °C/W, AEC-Q101 qualification, and compatibility with high-surge, low-loss power conversion topologies.

Technical Context

This Schottky rectifier uses dual-die configuration in a single TO-247AD package to support high-current, low-forward-drop operation. Its 150 V V_RRM, 300 A I_FSM, and 1.00 V V_F at 15 A enable robust performance in high-frequency switching applications where conduction loss minimization is critical.

The device operates across –55°C to +150°C junction temperature range and meets UL 94V-0 flammability rating, JESD 201 Class 2 whisker resistance, and RoHS/halogen-free compliance per IEC 61249-2-21 - confirming suitability for automotive under-hood and industrial environments.

FAQ

What is the maximum junction temperature rating for SR30150PTH?

The SR30150PTH has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official datasheet. This allows operation in demanding environments such as automotive engine compartments or sealed industrial enclosures. The device maintains specified electrical performance up to this limit when thermal design ensures case temperature remains within derated limits. SR30150PTH's +150°C rating exceeds standard Schottky rectifiers limited to +125°C, supporting higher ambient design margins.

Is SR30150PTH pin-compatible with other parts in the SR30xxPT family?

Yes, all SR30xxPT and SR30xxPTH parts share identical TO-247AD (TO-3P) package dimensions, terminal layout, and pin assignment - Anode, Cathode, and Cathode-connected tab. Mechanical compatibility is confirmed by TSC's Package Outline Dimensions drawing. However, electrical parameters (V_RRM, V_F, I_R) differ across voltage grades, so direct substitution requires verification of reverse voltage and thermal requirements. SR30150PTH is not a drop-in replacement for lower-voltage variants unless system-level stress analysis confirms margin.

Does SR30150PTH have AEC-Q101 qualification, and what does that cover?

Yes, SR30150PTH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and stated in the FEATURES section. This qualification covers stress tests including HTSL, TC, UHAST, and mechanical shock per AEC-Q101 Rev D, validating reliability for automotive electronic modules. The qualification applies specifically to the SR30150PTH variant - not the base SR30150PT - and confirms suitability for under-hood and body-control applications where zero-defect operation is mandated.

What is the forward voltage specification for SR30150PTH, and under what conditions is it measured?

SR30150PTH has a typical forward voltage (V_F) of 1.00 V at 15 A and 25°C junction temperature, per Electrical Specifications table. Measurement uses pulse test conditions (PW = 0.3 ms) to avoid self-heating effects. At higher temperatures (e.g., 100°C), V_F decreases slightly due to Schottky physics, but conduction loss remains lower than silicon PN rectifiers. This V_F value directly determines power dissipation: at 15 A, conduction loss is ~15 W, requiring appropriate thermal management using the 1.5 °C/W R_θJC.

How does the guard ring feature in SR30150PTH improve reliability?

The guard ring in SR30150PTH is a diffusion-based edge termination structure surrounding the active die area, designed to distribute electric field gradients and suppress premature avalanche breakdown at the silicon periphery. It enhances robustness against repetitive overvoltage transients (e.g., load dump in automotive systems) and improves long-term reliability under high dv/dt stress. This feature is confirmed in the FEATURES list and contributes to SR30150PTH's ability to sustain rated V_RRM with margin during real-world surge events - a key differentiator versus non-guarded Schottky rectifiers.
