Product details
Overview
SFAF505GHC0G from Taiwan Semiconductor is a 500V, 5A super fast rectifier diode in ITO-220AC package, featuring 35ns reverse recovery time, 1.30V max forward voltage at 5A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or output rectifier in high-frequency DC-DC converters.
For engineers reviewing the SFAF505GHC0G datasheet, SFAF505GHC0G pinout, SFAF505GHC0G application, or SFAF505GHC0G equivalent, key selection criteria include VRRM = 500V, IF = 5A, trr = 35ns, RθJC = 5°C/W, and AEC-Q101 compliance for under-hood power conversion designs.
Technical Context
This super fast rectifier uses a glass-passivated single die structure optimized for switching-mode power supplies operating above 20kHz. Its 35ns reverse recovery time and low 1.30V forward voltage minimize conduction and switching losses in flyback and forward converter topologies.
The ITO-220AC package provides direct heatsink mounting with 5°C/W junction-to-case thermal resistance, enabling stable operation up to 150°C junction temperature. Polarity is marked on the device body, and terminals are matte tin-plated per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 500 V - Maximum repetitive reverse voltage; defines safe blocking capability in 400–450V DC bus applications |
| IF | 5 A - Continuous average forward current; supports 60W+ output stages with proper heatsinking |
| trr | 35 ns - Reverse recovery time; enables efficient operation in 100–500kHz SMPS without excessive switching loss |
| VF (max) | 1.30 V @ 5A, 25°C - Forward voltage drop; determines conduction loss of ~6.5W at full load |
| RθJC | 5 °C/W - Junction-to-case thermal resistance; allows ~100W power dissipation margin before reaching 150°C TJ limit |
| IFSM | 125 A - Non-repetitive surge current (8.3ms); withstands inrush and fault transients in automotive DC-DC modules |
Pinout & Package
ITO-220AC package: 3-terminal through-hole outline with isolated tab (cathode-connected), matte tin-plated leads, UL 94V-0 molding compound, and 0.56 N·m maximum mounting torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry | Connected to switching node or transformer secondary; must handle peak currents up to 125A transiently |
| Cathode (Tab) | Output current exit / Heat path | Electrically and thermally connected to heatsink; requires insulating washer if chassis-grounded |
| Cathode (Lead 2) | Secondary cathode connection | Provides low-inductance return path parallel to tab; used when tab isolation is required |

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 | VRRM = 600V, trr = 30ns, VF = 1.35V @ 5A - slightly faster but higher VF; TO-220AC package | Preferred in 600V bus systems requiring <30ns trr; not AEC-Q101 qualified | Select when absolute minimum reverse recovery is critical and automotive qualification is not required. |
| ON Semi MUR560E | VRRM = 600V, trr = 50ns, VF = 1.25V @ 5A - lower VF but slower recovery; TO-220AC | Better for lower-frequency (<100kHz) converters where conduction loss dominates; no AEC-Q101 rating | Choose for cost-sensitive industrial supplies where 50ns trr is acceptable and AEC-Q101 is unnecessary. |
Compared with STTH5L06H and MUR560E, the SFAF505GHC0G uniquely balances 500V rating, 35ns trr, 1.30V VF, and AEC-Q101 qualification-making it optimal for automotive 48V DC-DC modules where reliability, speed, and voltage margin are jointly constrained.

FAQ
What is the maximum junction temperature rating for SFAF505GHC0G?
The SFAF505GHC0G has a maximum junction temperature (TJMAX) of +150°C, verified per AEC-Q101 stress testing. This rating enables operation in under-hood automotive environments and uncooled industrial enclosures when mounted to an appropriate heatsink with ≤5°C/W system thermal resistance. Derating curves confirm 5A continuous current is sustainable up to 125°C case temperature.
Is SFAF505GHC0G pin-compatible with standard ITO-220AC rectifiers?
Yes, SFAF505GHC0G uses the industry-standard ITO-220AC footprint with Anode (Lead 1), Cathode (Tab), and Cathode (Lead 2) terminal configuration. Mechanical drawings confirm identical lead pitch, tab dimensions, and mounting hole placement to legacy ITO-220AC devices such as BYV26E or STTH5L06, enabling direct PCB layout reuse.
Does SFAF505GHC0G meet halogen-free and RoHS requirements?
Yes, SFAF505GHC0G complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all terminations use matte tin plating without lead, cadmium, mercury, hexavalent chromium, or PBB/PBDE.
What is the reverse recovery time test condition for SFAF505GHC0G?
The specified 35ns reverse recovery time (trr) for SFAF505GHC0G is measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A per JEDEC JESD24-10, using a standardized test circuit with 1Ω source impedance and 50ns current fall time. This reflects real-world behavior in hard-switched flyback and forward converters.
How does the "H" suffix in SFAF505GHC0G denote AEC-Q101 qualification?
The "H" in SFAF505GHC0G explicitly indicates AEC-Q101 qualification per the manufacturer's ordering code convention (per datasheet Note 2). This includes full stress testing across temperature cycling, high-temperature reverse bias, ESD, and mechanical shock-verified by Taiwan Semiconductor's certified lab and documented in their AEC-Q101 certificate of compliance for the SFAF50xGH series.
