Product details
Overview
SFAF504GHC0G 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 converter freewheeling paths.
For engineers reviewing the SFAF504GHC0G datasheet, SFAF504GHC0G pinout, SFAF504GHC0G application, or SFAF504GHC0G equivalent, key selection criteria include VRRM = 200 V, trr ≤ 35 ns, VF ≤ 0.975 V @ 5 A, AEC-Q101 compliance, and ITO-220AC thermal performance (RθJC = 5 °C/W).
Technical Context
This super fast rectifier employs a glass passivated silicon junction to achieve low forward voltage and high surge robustness. Its 35 ns reverse recovery time enables efficient operation in high-frequency switching topologies up to several hundred kHz.
The device operates across -55°C to +150°C junction temperature range with 125 A non-repetitive surge capability (8.3 ms half-sine) and 5 °C/W junction-to-case thermal resistance - critical for thermally constrained automotive and industrial power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - supports 200 V DC bus or 140 V RMS input in AC-DC front ends |
| IF | 5 A continuous - delivers rated current without derating below 100°C case temperature |
| trr | 35 ns - minimizes switching losses in 100–500 kHz SMPS designs |
| VF | 0.975 V @ 5 A, 25°C - reduces conduction loss vs. standard fast rectifiers (typ. >1.1 V) |
| RθJC | 5 °C/W - enables direct heatsink mounting with predictable thermal rise under full load |
| IFSM | 125 A @ 8.3 ms - withstands inrush and transient overloads in motor drives and converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06D | VRRM = 600 V, trr = 35 ns, VF = 1.15 V @ 5 A - higher voltage rating but higher VF | Preferred where 600 V isolation or legacy 400 V bus margin required | Select when system requires >200 V reverse blocking; accept 180 mV higher conduction loss |
| ON-SEMI MUR520 | VRRM = 200 V, trr = 35 ns, VF = 0.98 V @ 5 A - identical VRRM/trr, slightly higher VF | Drop-in replacement in non-AEC-Q101 designs; same footprint and thermal profile | Use where AEC-Q101 is not mandated; verify lead finish compatibility with assembly process |
Compared with STTH5L06D and MUR520, SFAF504GHC0G provides AEC-Q101 qualification and lower VF (0.975 V), making it optimal for thermally constrained automotive DC-DC stages where 200 V blocking suffices and reliability is prioritized over voltage headroom.

FAQ
What is the maximum junction temperature rating for SFAF504GHC0G?
The SFAF504GHC0G has a maximum junction temperature (TJMAX) of +150°C, validated across its full operating range from -55°C to +150°C. This rating enables reliable operation in under-hood automotive environments and sealed industrial enclosures. Thermal design must maintain junction temperature below this limit using the specified RθJC = 5 °C/W and appropriate heatsinking. The SFAF504GHC0G datasheet confirms this value under Absolute Maximum Ratings.
Is SFAF504GHC0G pin-compatible with other ITO-220AC rectifiers like MUR520?
Yes, SFAF504GHC0G uses the standard ITO-220AC package with identical mechanical dimensions and terminal layout as MUR520 and similar devices. Anode (lead 1), cathode (lead 2), and metal tab alignment match industry-standard ITO-220AC footprints. However, SFAF504GHC0G includes AEC-Q101 qualification and green molding compound - verify solder profile and cleaning compatibility before drop-in substitution. The SFAF504GHC0G mechanical drawings confirm full package interchangeability.
What does the 'H' and 'C0G' suffix mean in SFAF504GHC0G?
In SFAF504GHC0G, 'H' indicates AEC-Q101 qualification per ordering code documentation, while 'C0G' denotes green (halogen-free) compound and specific date/factory coding per TSC's marking convention. The 'C0G' suffix does not indicate capacitor characteristics; it is a TSC internal marking variant confirming RoHS and IEC 61249-2-21 compliance. All SFAF504GHC0G units shipped meet these material and qualification requirements.
What is the reverse leakage current specification for SFAF504GHC0G at elevated temperature?
At TJ = 125°C and rated VR, the SFAF504GHC0G exhibits a maximum reverse leakage current (IR) of 400 µA, as specified in the Electrical Specifications table. At 25°C, IR is limited to 10 µA. This behavior is consistent across the SFAF501G–SFAF508G family and reflects the device's glass-passivated junction stability. These values are measured under standardized pulse conditions (PW = 30 ms) per the SFAF504GHC0G datasheet.
Can SFAF504GHC0G be used in place of SFAF504G in automotive designs?
Yes - SFAF504GHC0G is the AEC-Q101 qualified version of SFAF504G, sharing identical electrical parameters (VRRM = 200 V, trr = 35 ns, VF = 0.975 V), thermal specs, and package. The 'H' suffix explicitly denotes AEC-Q101 compliance, making SFAF504GHC0G the preferred choice for automotive applications requiring qualification evidence. No circuit or layout changes are needed when upgrading from SFAF504G to SFAF504GHC0G.
