Product details
Overview
SFF506GHC0G from Taiwan Semiconductor is a 400 V, 5 A AEC-Q101-qualified super fast rectifier diode in ITO-220AB package with dual-die configuration, 1.30 V forward voltage at 2.5 A/25°C, 35 ns reverse recovery time, and 5.5 °C/W junction-to-case thermal resistance-used in automotive-grade DC-DC converters and switching inverters.
For engineers reviewing the SFF506GHC0G datasheet, SFF506GHC0G pinout, SFF506GHC0G application, or SFF506GHC0G equivalent, key selection criteria include peak reverse voltage (400 V), surge current capability (70 A), thermal performance (RθJC = 5.5 °C/W), AEC-Q101 qualification status, and ITO-220AB mounting compatibility.
Technical Context
This super fast rectifier employs optimized epitaxial structure and low-Qrr design to achieve 35 ns reverse recovery time and low forward voltage (1.30 V), enabling high-efficiency operation in high-frequency switching topologies. Its dual-die configuration supports symmetrical current sharing and thermal distribution across the ITO-220AB case.
The device meets UL 94V-0 flammability rating and JESD201 Class 2 whisker resistance, with matte tin-plated leads compliant to J-STD-002 solderability standards-critical for automotive under-hood reliability and reflow process stability.

| IF | 5 A - continuous average forward current; determines steady-state power handling in DC-DC output stages |
| IFSM | 70 A - non-repetitive surge current (8.3 ms half-sine); enables robustness against load dump or startup transients |
| VF | 1.30 V @ 2.5 A, 25°C - low conduction loss per diode; reduces power dissipation in high-duty-cycle rectification |
| trr | 35 ns - ultra-fast reverse recovery; minimizes switching losses and EMI in >100 kHz SMPS designs |
| RθJC | 5.5 °C/W - thermal resistance from junction to case; enables direct heatsink mounting without thermal interface degradation |
| Junction Temp | –55 to +150°C - extended temperature range supports under-hood automotive deployment |

FAQ
What is the peak repetitive reverse voltage rating for SFF506GHC0G?
The SFF506GHC0G has a peak repetitive reverse voltage (VRRM) rating of 400 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version I2105), where SFF506G is explicitly assigned 400 V under the VRRM column. It defines the maximum DC or sinusoidal AC reverse voltage the device can block continuously without breakdown.
Is SFF506GHC0G qualified to AEC-Q101 standards?
Yes, SFF506GHC0G is AEC-Q101 qualified. The "H" suffix in the ordering code denotes AEC-Q101 qualification, and the datasheet states "AEC-Q101 qualified available" under FEATURES. This applies specifically to SFF506GHC0G, as confirmed by the ordering information note specifying "'H' means AEC-Q101 qualified" and the marking diagram indicating "H" as part of the device code.
What is the forward voltage drop of SFF506GHC0G at rated current?
The forward voltage (VF) of SFF506GHC0G is 1.30 V at IF = 2.5 A and TJ = 25°C, per the Electrical Specifications table. This value is specified for the SFF505G–SFF506G group and represents the typical maximum conduction loss under standard test conditions-critical for calculating power dissipation in thermal design.
What package type does SFF506GHC0G use, and what are its mechanical features?
SFF506GHC0G uses the ITO-220AB package: an insulated thermoplastic outline with integral metal tab, UL 94V-0 rated molding compound, matte tin-plated leads compliant to J-STD-002, and polarity marked on the case. Mounting torque must not exceed 0.56 N·m, and the device passes JESD201 Class 2 whisker testing.
What is the reverse recovery time (trr) specification for SFF506GHC0G?
The reverse recovery time (trr) for SFF506GHC0G is 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is listed in the Electrical Specifications table for the SFF505G–SFF508G group and directly impacts switching loss and EMI performance in high-frequency power converters.
