Taiwan Semiconductor Corporation SR3060PTH

Overview

SR3060PTH from Taiwan Semiconductor is a 30A, 60V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.70 V forward voltage at 15 A and 25°C, 300 A surge capability, and junction-to-case thermal resistance of 1.5°C/W - deployed in automotive-grade SMPS and DC-DC converters.

For engineers reviewing the SR3060PTH datasheet, SR3060PTH pinout, SR3060PTH application, or SR3060PTH equivalent, key selection criteria include repetitive peak reverse voltage (60 V), forward current rating (30 A), thermal performance (R_θJC = 1.5°C/W), AEC-Q101 qualification status, and TO-247AD mechanical compatibility for high-power board mounting.

Technical Context

This dual-die Schottky rectifier operates with low conduction loss due to its metal-semiconductor junction, enabling high-efficiency power conversion in switching topologies. Its guard ring structure provides overvoltage protection, and it supports continuous operation up to 150°C junction temperature.

The device delivers 15 mA reverse leakage at 60 V and 100°C, maintains 1000 µA max IR at 25°C, and exhibits stable forward characteristics across pulse widths from 0.3 ms to 30 ms - critical for transient load handling in automotive power supplies.

FAQ

What is the maximum junction temperature rating for SR3060PTH?

The SR3060PTH has a maximum junction temperature (T_J) rating of +150°C, verified per AEC-Q101 stress test conditions. This allows operation in under-hood automotive environments and high-ambient industrial settings. The SR3060PTH achieves this rating while maintaining 1000 µA reverse leakage at 25°C and 15 mA at 100°C - critical for thermal design margin in sealed enclosures.

Is SR3060PTH pin-compatible with other TO-247AD Schottky rectifiers?

Yes, SR3060PTH uses the standard TO-247AD (TO-3P) footprint with Anode–Cathode–Tab pinout, matching industry-standard mechanical dimensions per JEP95 DO-201AD. However, electrical compatibility depends on V_RRM, I_F, and thermal specs - always verify VF, I_FSM, and R_θJC before substitution. The SR3060PTH's 1.5°C/W R_θJC is tighter than many TO-247AD competitors.

Does SR3060PTH require a heatsink in typical operation?

Yes, SR3060PTH requires a heatsink when operating above 15 A continuous current or in ambient temperatures exceeding 50°C. Its R_θJC = 1.5°C/W and 30 A rating mean junction temperature rises ~45°C above case temperature at full load - exceeding 150°C limit without thermal management. Mounting torque must not exceed 1.13 N·m to avoid die cracking.

What does the 'H' suffix in SR3060PTH signify?

The 'H' suffix in SR3060PTH indicates full AEC-Q101 qualification per Rev H2103 specification. This includes passing HTGB (1000 hrs @ 150°C), HTRB (1000 hrs @ 150°C + rated V_R), and temperature cycling (-40°C to +150°C, 1000 cycles). Non-H versions (e.g., SR3060PT) lack this validation and are restricted to commercial applications.

How does SR3060PTH compare to silicon fast recovery diodes in efficiency?

SR3060PTH delivers significantly higher efficiency than silicon fast recovery diodes like MUR3060CTG due to its 0.70 V forward voltage versus ~1.7 V - reducing conduction loss by ~59% at 15 A. This translates to measurable thermal reduction: at 30 A, SR3060PTH dissipates ~21 W vs. ~51 W for silicon, enabling smaller heatsinks and quieter cooling in space-constrained designs.
