Product details
Overview
SFAF504GH from Taiwan Semiconductor is a 5 A, 200 V repetitive peak reverse voltage (VRRM) super fast rectifier diode in ITO-220AC package, featuring 35 ns reverse recovery time (trr), 0.975 V forward voltage at 5 A/25°C, and AEC-Q101 qualification for automotive-grade reliability - used in DC-DC converters and freewheeling paths in switching inverters.
For engineers reviewing the SFAF504GH datasheet, SFAF504GH pinout, SFAF504GH application, or SFAF504GH equivalent, key selection criteria include its 200 V VRRM, 125 A IFSM, 5 °C/W RθJC, AEC-Q101 qualification status, and ITO-220AC thermal-mechanical compatibility with high-power PCB mounting.
Technical Context
The SFAF504GH employs a glass passivated single-die silicon junction optimized for high-efficiency switching applications. Its 35 ns trr and low 0.975 V VF at 5 A reduce switching losses and conduction heating in high-frequency SMPS topologies.
Designed for automotive and industrial environments, it supports continuous operation up to +150 °C junction temperature and withstands 125 A non-repetitive surge current (8.3 ms half-sine), with UL Recognition (E-326243) and halogen-free compliance per IEC 61249-2-21.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06H | 600 V VRRM, 5 A IF, 35 ns trr, same ITO-220AC package, but not AEC-Q101 qualified | Higher voltage margin suitable for universal-input AC-DC; lacks automotive qualification | Select when higher reverse voltage headroom is needed and AEC-Q101 is not required |
| VS-5EWH06-M3/45 | 600 V VRRM, 5 A IF, 30 ns trr, TO-220AC package, AEC-Q101 qualified, but 0.99 V VF slightly higher | Better trr performance for ultra-high-frequency designs; identical qualification level | Select when minimizing reverse recovery time is prioritized over marginal VF increase |
Compared with STTH5L06H and VS-5EWH06-M3/45, the SFAF504GH offers optimal balance of 200 V rating, AEC-Q101 compliance, and low VF for cost-sensitive automotive and industrial 24–48 V systems - avoiding over-specification while meeting thermal and reliability targets.

FAQ
What is the peak repetitive reverse voltage rating of the SFAF504GH?
The SFAF504GH has a repetitive peak reverse voltage (VRRM) rating of 200 V, verified per the manufacturer's absolute maximum ratings table. This value defines the maximum reverse-biased voltage the device can block repeatedly without breakdown and is critical for selecting appropriate input voltage margins in DC-DC and inverter designs using the SFAF504GH.
Is the SFAF504GH AEC-Q101 qualified, and what does that cover?
Yes, the SFAF504GH is AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST), confirming suitability for automotive under-hood and powertrain applications where reliability under thermal and electrical stress is mandatory for the SFAF504GH.
What is the forward voltage drop of the SFAF504GH at rated current?
The SFAF504GH exhibits a typical forward voltage (VF) of 0.975 V at 5 A forward current and 25 °C junction temperature, per the electrical specifications table. This low VF directly reduces conduction losses and improves thermal performance in high-duty-cycle applications such as continuous-output DC-DC converters using the SFAF504GH.
Does the SFAF504GH have an isolated tab, and how is it electrically configured?
Yes, the SFAF504GH uses the ITO-220AC package, which features an electrically isolated metal tab. The tab serves solely as a thermal interface - it is not connected to either the anode or cathode. This isolation allows direct mounting to a common heatsink without requiring insulating hardware, simplifying thermal design for the SFAF504GH in high-power layouts.
What is the reverse recovery time (trr) specification for the SFAF504GH, and under what conditions is it measured?
The SFAF504GH has a maximum reverse recovery time (trr) of 35 ns, measured under the conditions: forward current IF = 0.5 A, reverse current IR = 1.0 A, and reverse recovery current Irr = 0.25 A. This parameter confirms fast switching behavior essential for minimizing switching losses in high-frequency power converters using the SFAF504GH.
