Taiwan Semiconductor Corporation UG06C

Overview

UG06C from Taiwan Semiconductor is a single-die ultrafast rectifier diode rated for 150 V repetitive peak reverse voltage (V_RRM), 0.6 A average forward current (I_F), and 15 ns reverse recovery time (t_rr), designed for high-efficiency DC-DC converters and freewheeling paths in switching power supplies.

For engineers reviewing the UG06C datasheet, UG06C pinout, UG06C application, or UG06C equivalent, key selection criteria include its TS-1 package thermal resistance (R_θJL = 28 °C/W), low forward voltage (V_F ≤ 0.95 V at 0.6 A), and AEC-Q101 qualification option - critical for automotive-grade power conversion reliability.

Technical Context

The UG06C operates as a unidirectional silicon PN junction rectifier with ultrafast recovery optimized for high-frequency switching topologies. Its 15 ns t_rr enables reduced switching losses in 100–500 kHz SMPS designs, while the 150 V V_RRM rating supports mid-voltage bus applications such as 48 V telecom and industrial DC distribution.

Thermally, the TS-1 package delivers R_θJL = 28 °C/W and R_θJA = 97 °C/W, allowing sustained 0.6 A conduction up to +125 °C ambient when mounted on ≥1 cm² copper. The cathode-band polarity marking and pure tin-plated leads comply with J-STD-002 solderability and JESD201 Class 2 whisker resistance.

UG06C is available at Aetrix Electronics and suitable for DC-DC converters, switching inverters, and freewheeling applications requiring stable component supply, automotive-grade traceability, and long-term industrial lifecycle support.

Supply support for UG06C includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, specializing in power rectifiers, TVS devices, and automotive-qualified components since 1979.

The UG06x series belongs to TSC's ultrafast rectifier product line, engineered specifically for high-frequency, high-reliability power conversion in automotive body electronics, industrial SMPS, and telecom infrastructure where low t_rr and robust thermal performance are design-critical.

FAQ

What is the maximum junction temperature rating for UG06C?

The UG06C has a maximum junction temperature (T_J) of +150 °C, verified per absolute maximum ratings in the G2104 datasheet. This allows continuous operation at full 0.6 A load in ambient temperatures up to +125 °C when mounted on ≥1 cm² copper area. Derating curves confirm usable current down to 0.35 A at +150 °C ambient, making UG06C suitable for sealed enclosures without active cooling.

Does UG06C have AEC-Q101 qualification?

The base UG06C is not AEC-Q101 qualified, but the variant UG06CH (ordering code with "H" suffix) is fully AEC-Q101 qualified per Rev G2104 documentation. UG06CH undergoes extended temperature cycling, mechanical shock, and humidity testing for automotive under-hood use. For non-automotive industrial applications, standard UG06C meets all electrical and thermal specs without qualification overhead.

What is the reverse recovery time (t_rr) test condition for UG06C?

The UG06C reverse recovery time of 15 ns is measured under the standardized condition: I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A, with specified test circuit per Figure 6 in the G2104 datasheet. This reflects real-world hard-switching behavior in buck and flyback converters, not idealized small-signal conditions - confirming suitability for 200–500 kHz designs.

How does UG06C's forward voltage compare to similar 0.6 A rectifiers?

UG06C specifies V_F ≤ 0.95 V at 0.6 A and 25 °C, which is 0.05–0.15 V lower than typical competitors like STTH06S06D (V_F ≈ 1.05 V) and MUR0620 (V_F ≈ 1.10 V). This reduction directly lowers conduction loss by ~120 mW at full load, easing thermal design in dense PCB layouts where UG06C's TS-1 package excels.

What packaging options are available for UG06C?

UG06C is supplied in two standard configurations: 5,000-piece tape-and-reel (ordering code UG06C) and 3,000-piece ammo box (ordering code UG06C A0G). Both use the TS-1 package with green molding compound and cathode-band polarity marking. No tray or bulk options are offered; all units meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
