Product details
Overview
SF23GHR0G from Taiwan Semiconductor is a 2 A, 150 V super fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 2 A and 25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or output rectifier in high-frequency switching power supplies.
For engineers reviewing the SF23GHR0G datasheet, SF23GHR0G pinout, SF23GHR0G application, or SF23GHR0G equivalent, key selection criteria include its 150 V repetitive peak reverse voltage, 50 A surge current rating, junction-to-ambient thermal resistance of 65°C/W, glass-passivated junction, and RoHS/halogen-free compliance.
Technical Context
This single-die, planar epitaxial super fast rectifier uses a glass-passivated junction to ensure stable performance under thermal cycling and humidity stress. Its 35 ns trr enables efficient operation in DC-DC converters switching above 100 kHz.
The device operates across –55°C to +150°C junction temperature range with 16°C/W junction-to-case thermal resistance, supporting high-reliability freewheeling in compact, thermally constrained layouts where low VF and fast recovery minimize conduction and switching losses.
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 |
|---|---|---|---|
| STTH2R06 | Same 2 A / 600 V rating but higher VF (1.7 V typ); trr = 35 ns; TO-220AC package | Requires heatsink for >1 A continuous; unsuitable for space-constrained DO-15 footprints | Select when higher VRRM margin is needed and board area allows TO-220 mounting |
| ON Semiconductor MUR220 | 2 A / 200 V; VF = 0.93 V; trr = 35 ns; DO-15 package; no AEC-Q101 qualification | Lacks automotive qualification; suitable for industrial/commercial only | Choose for cost-sensitive non-automotive designs where 200 V VRRM suffices |
Compared with STTH2R06 and MUR220, SF23GHR0G uniquely combines AEC-Q101 qualification, DO-15 footprint, 150 V VRRM, and 0.95 V VF-making it optimal for automotive auxiliary power modules where space, reliability, and efficiency are jointly constrained.

FAQ
What is the maximum junction temperature rating for SF23GHR0G?
The SF23GHR0G has a maximum junction temperature (TJ MAX) of +150°C, verified per JEDEC JESD22-A108. This rating allows operation in under-hood automotive environments and high-ambient industrial enclosures. Derating curves in the SF23GHR0G datasheet define usable current versus ambient temperature, with full 2 A capability maintained up to +75°C ambient when mounted on 1-inch² copper pad.
Is SF23GHR0G pin-compatible with other DO-15 rectifiers like 1N4007?
No-SF23GHR0G is not pin-compatible with 1N4007 in functional or electrical terms. While both use DO-15 mechanical form factor, SF23GHR0G is a super fast rectifier (35 ns trr, 0.95 V VF), whereas 1N4007 is a general-purpose rectifier (30 µs trr, 1.1 V VF). Substitution requires circuit revalidation due to differences in reverse recovery behavior and thermal performance.
Does SF23GHR0G meet automotive qualification standards?
Yes-SF23GHR0G is explicitly AEC-Q101 qualified, as confirmed by Taiwan Semiconductor's H2105 datasheet revision and ordering code suffix "H". This qualification covers stress tests including HTGB, HTRB, TCT, and UHAST, validating suitability for automotive powertrain, body control, and infotainment systems.
What is the reverse leakage current specification for SF23GHR0G at elevated temperature?
At TJ = 125°C and rated VR (150 V), the SF23GHR0G exhibits a maximum reverse leakage current (IR) of 100 µA, per the datasheet's Electrical Specifications table. At 25°C and same VR, IR is limited to 5 µA. This low, well-characterized leakage supports stable operation in high-temperature battery management and motor control applications.
How does the glass passivation in SF23GHR0G improve long-term reliability?
Glass passivation in SF23GHR0G forms a hermetic, chemically inert barrier over the silicon junction, preventing oxidation, metal migration, and moisture-induced failure mechanisms. This directly extends mean time to failure (MTTF) in humid or thermally cycled environments-critical for automotive under-hood modules and outdoor LED drivers where field lifetimes exceed 10 years.
