Taiwan Semiconductor Corporation SRAF1660HC0G

Overview

SRAF1660HC0G from Taiwan Semiconductor is a 16A, 60V AEC-Q101-qualified Schottky barrier rectifier in ITO-220AC package, featuring 0.70V forward voltage at 16A/25°C, 275A surge capability, and 4°C/W junction-to-case thermal resistance-used in automotive-grade DC-DC converters and SMPS secondary-side rectification.

For engineers reviewing the SRAF1660HC0G datasheet, SRAF1660HC0G pinout, SRAF1660HC0G application, or SRAF1660HC0G equivalent, key selection factors include its 60V repetitive peak reverse voltage, AEC-Q101 qualification status, TJ max of +150°C, low VF for high-efficiency operation, and ITO-220AC mounting compatibility with standard heatsink interfaces.

Technical Context

This single-die Schottky rectifier operates with guard ring over-voltage protection and supports continuous forward current up to 16A at case temperatures ≤100°C. Its 10,000 V/µs critical dv/dt rating enables stable switching in fast-rising voltage environments such as synchronous rectifier circuits and high-frequency DC-DC topologies.

Thermally optimized for power-dense designs, it delivers 4°C/W junction-to-case resistance and meets JESD201 Class 2 whisker resistance. The matte tin-plated leads comply with J-STD-002 solderability and UL 94V-0 flammability requirements for automotive and industrial mounting.

FAQ

What does the 'H' suffix in SRAF1660HC0G indicate?

The 'H' in SRAF1660HC0G denotes AEC-Q101 qualification-confirmed by Taiwan Semiconductor's test reports covering high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. This makes the SRAF1660HC0G suitable for automotive power modules where reliability under thermal and vibration stress is mandatory.

Is SRAF1660HC0G pin-compatible with standard TO-220AC rectifiers?

No-SRAF1660HC0G uses the ITO-220AC package, which features an electrically isolated metal tab, unlike standard TO-220AC. While physical footprint and lead spacing match, the isolation requires verification of heatsink grounding strategy. Direct substitution without layout review may cause short circuits in non-isolated thermal designs.

What is the maximum allowable case temperature for continuous operation of SRAF1660HC0G?

The SRAF1660HC0G supports continuous operation up to +100°C case temperature at rated 16A forward current, as defined in its derating curve. At higher case temperatures, current must be reduced linearly to maintain junction temperature ≤+150°C. Derating begins at +100°C and reaches zero current at +150°C.

Does SRAF1660HC0G require a thermal pad or insulator when mounted to a heatsink?

No thermal pad or insulator is required-the ITO-220AC package integrates electrical isolation into the molded compound. The metal tab is inherently insulated from both anode and cathode leads. However, mechanical interface flatness and mounting torque (≤0.56 N·m) must be controlled to ensure optimal thermal contact and avoid package cracking.

How does the guard ring in SRAF1660HC0G improve system-level reliability?

The guard ring in SRAF1660HC0G provides edge termination that suppresses avalanche breakdown at the die periphery, increasing tolerance to voltage transients like load dump or inductive kickback. In practice, this eliminates need for external RC snubbers in flyback converters using SRAF1660HC0G, reducing component count and improving power density in automotive SMPS designs.
