Product details
Overview
UGF12JD from Taiwan Semiconductor is a single-die ultra-fast recovery rectifier diode rated for 12 A average forward current, 600 V repetitive peak reverse voltage, and 100 A non-repetitive surge current, operating up to 175 °C junction temperature in DC-DC converters and switching inverters.
For engineers reviewing the UGF12JD datasheet, UGF12JD pinout, UGF12JD application, or UGF12JD equivalent, key selection criteria include trr ≤ 25 ns (typ), Qrr = 90 nC at 125 °C, VF = 3.1 V at 12 A/25 °C, RθJC = 2.4 °C/W, and ITO-220AC package compatibility with high-di/dt freewheeling paths.
Technical Context
The UGF12JD employs an optimized ultra-fast recovery epitaxial structure enabling low Qrr (90 nC) and fast trr (13–25 ns) under defined dIF/dt conditions (−200 A/μs), supporting high-frequency switching in hard-switched topologies. Its 175 °C TJ rating and 2.4 °C/W junction-to-case thermal resistance allow sustained operation in thermally constrained industrial power stages.
Designed for unidirectional conduction in flyback, boost, and freewheeling configurations, the device delivers stable IR ≤ 0.5 µA at 25 °C and ≤ 100 µA at 125 °C, with VF tightly specified at 3.1 V (typ) under 12 A DC load - critical for efficiency-critical SMPS output rectification.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH12R06DJF | 600 V VRRM, 12 A IF, trr = 22 ns (typ), VF = 2.9 V (typ) at 12 A, same ITO-220AC package | Slightly lower VF improves conduction loss; identical thermal and surge specs support drop-in replacement in most layouts | Preferred where <0.2 V VF reduction yields measurable efficiency gain at full load |
| IXYS MUR1260CT | 600 V VRRM, 12 A IF per die, dual common-cathode configuration, trr = 35 ns (max), VF = 3.3 V (max) at 12 A | Dual-die layout requires PCB redesign; higher trr increases switching loss in >200 kHz designs | Only suitable when dual-output topology or legacy footprint mandates dual-diode form factor |
Compared with STTH12R06DJF and IXYS MUR1260CT, the UGF12JD offers balanced trade-offs: tighter trr/Qrr spec than MUR1260CT for high-frequency use, and superior high-temperature IR stability versus STTH12R06DJF - making it optimal for thermally aggressive industrial converters.

FAQ
What is the maximum junction temperature rating for UGF12JD?
The UGF12JD has a maximum junction temperature (TJ) rating of +175 °C, verified per absolute maximum ratings table. This allows continuous operation in high-ambient environments such as enclosed industrial power supplies or under-hood automotive auxiliary converters. Derating curves confirm usable current capacity down to 0 A at 175 °C case temperature, with full 12 A rated at ≤ 85 °C case.
Does UGF12JD have AEC-Q101 qualification?
The base UGF12JD is not AEC-Q101 qualified; however, the variant UGF12JDH - explicitly marked with "H" suffix in the ordering code - is AEC-Q101 qualified per JESD22-A108. Both share identical electrical and thermal specifications, differing only in test documentation and traceability. UGF12JDH is intended for automotive-grade power conversion modules requiring stress-tested reliability.
What is the reverse recovery time (trr) specification for UGF12JD?
The UGF12JD specifies trr = 13 ns (typ) and ≤ 25 ns (max) under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A test conditions. At higher stress (IF = 1 A, VR = 30 V, dIF/dt = −50 A/μs), trr is ≤ 45 ns. These values are measured per JEDEC standards and reflect true ultra-fast behavior essential for minimizing switching loss in 200–500 kHz converters.
How does the thermal resistance RθJC of UGF12JD impact heatsink design?
The UGF12JD has a typical junction-to-case thermal resistance (RθJC) of 2.4 °C/W. For a 12 A load with VF = 3.1 V, power dissipation is ~37.2 W; with RθJC = 2.4 °C/W, this yields a 89 °C junction-to-case rise. To maintain TJ ≤ 150 °C at TA = 70 °C, the heatsink must provide ≤ 0.65 °C/W total thermal resistance (case-to-ambient), achievable with medium-profile extruded aluminum heatsinks.
What marking code appears on the UGF12JD device body?
The UGF12JD is laser-marked with its full part number "UGF12JD" on the top surface, along with green compound indicator "G", factory code "F", and date code in YWW format (e.g., "2426" for week 26 of 2024). This matches the official marking diagram in the datasheet and confirms authenticity and traceability for production audits.
