Product details

Overview

UG06CH from Taiwan Semiconductor is an AEC-Q101-qualified ultrafast rectifier diode rated for 200 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 automotive-grade switching inverters.

For engineers reviewing the UG06CH datasheet, UG06CH pinout, UG06CH application, or UG06CH 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 guaranteed AEC-Q101 qualification for under-hood automotive power stages.

Technical Context

The UG06CH operates as a single-die, unidirectional ultrafast recovery rectifier with a cathode-banded polarity marking and pure tin-plated leads compliant with J-STD-002 solderability. Its 15 ns t_rr enables high-frequency switching up to ~1 MHz in hard-switched topologies while maintaining low switching loss.

Thermally, it features a junction-to-lead resistance of 28 °C/W and a maximum junction temperature of +150 °C, supporting operation in ambient temperatures up to +125 °C when mounted on PCBs with adequate copper area per TS-1 footprint. Reverse leakage remains ≤150 µA at 125 °C and rated V_R.

Key Specifications

V_RRM	200 V - supports input rails up to 170 V DC in offline SMPS or 48 V automotive systems with margin
I_F	0.6 A continuous - suitable for low-power auxiliary supplies and gate-drive bias rails
t_rr	15 ns - enables efficient operation in >200 kHz switching converters without excessive turn-off loss
V_F	≤0.95 V @ 0.6 A, 25°C - reduces conduction loss in compact, thermally constrained layouts
R_θJL	28 °C/W - allows direct thermal coupling to PCB copper for passive cooling without heatsink
I_FSM	40 A @ 8.3 ms - withstands inrush and fault currents in protected DC-DC stages

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultrafast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH06S06D	600 V V_RRM, 0.85 V V_F, 25 ns t_rr, TO-277 package	Higher voltage rating but slower recovery and higher conduction loss	Select when >200 V reverse blocking is required; not drop-in due to different package and pinout
ES1JH	600 V V_RRM, 1.7 V V_F, 35 ns t_rr, SMA package	Higher V_F increases conduction loss; larger R_θJA limits power density	Use only in non-automotive, low-frequency (<100 kHz) applications where cost is primary constraint

Compared with STTH06S06D and ES1JH, the UG06CH delivers superior high-frequency efficiency via its 15 ns t_rr and 0.95 V V_F, while its AEC-Q101 qualification and TS-1 thermal performance make it uniquely suited for automotive and high-reliability industrial DC-DC stages where layout space and thermal headroom are constrained.

FAQ

What is the peak repetitive reverse voltage rating for UG06CH?

The UG06CH has a peak repetitive reverse voltage (V_RRM) rating of 200 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version G2104). This rating defines the maximum reverse voltage the device can block repeatedly without breakdown under normal operating conditions, making it suitable for 48 V automotive systems with transient margin and 100–200 V DC bus applications.

Is UG06CH qualified to AEC-Q101 standards?

Yes, UG06CH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and stated in the FEATURES section of the datasheet. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing, confirming suitability for automotive power electronics such as engine control units and ADAS power supplies.

What is the reverse recovery time (t_rr) of UG06CH and how is it measured?

The UG06CH has a maximum reverse recovery time (t_rr) of 15 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, per the Electrical Specifications table. This value reflects the time required for the diode to transition from forward conduction to reverse blocking, directly impacting switching loss and EMI in high-frequency converters.

What package does UG06CH use and what are its thermal characteristics?

UG06CH uses the TS-1 surface-mount package, with a junction-to-lead thermal resistance (R_θJL) of 28 °C/W and junction-to-ambient resistance (R_θJA) of 97 °C/W. The TS-1 case features UL 94V-0 molding compound, pure tin-plated leads, and a cathode band for polarity identification-enabling reliable reflow soldering and efficient PCB-level heat dissipation.

How does the forward voltage of UG06CH compare to similar ultrafast rectifiers?

The UG06CH exhibits a maximum forward voltage (V_F) of 0.95 V at 0.6 A and 25°C, which is lower than many competing ultrafast rectifiers such as ES1JH (1.7 V) and comparable to STTH06S06D (0.85 V). This lower V_F reduces conduction losses and improves thermal performance in compact, high-density power designs where efficiency and temperature rise are critical.
