Product details

Overview

UG06B A1G from Taiwan Semiconductor is an AEC-Q101-qualified ultrafast rectifier diode with 100 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 power supplies.

For engineers reviewing the UG06B A1G datasheet, UG06B A1G pinout, UG06B A1G application, or UG06B A1G equivalent, key selection criteria include its TS-1 package thermal resistance (R_θJL = 28 °C/W), 40 A surge rating (I_FSM), and low 0.95 V forward voltage at 0.6 A - critical for minimizing conduction loss in compact switching topologies.

Technical Context

The UG06B A1G is a single-die, planar-passivated silicon ultrafast rectifier optimized for high-frequency switching applications. Its 15 ns reverse recovery time and 9 pF junction capacitance enable efficient operation in 100–500 kHz SMPS designs while maintaining low EMI generation.

Rated for continuous operation up to +150 °C junction temperature and qualified per AEC-Q101, the device supports automotive-grade reliability under thermal cycling and mechanical stress. The TS-1 package features pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - maximum non-repetitive reverse blocking voltage; defines usable input range in 12 V/24 V automotive DC-DC stages
I_F	0.6 A - continuous average forward current at T_L = 75 °C; sets output power capability in low-power auxiliary rails
t_rr	15 ns - measured at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A; enables >300 kHz switching without excessive turn-off loss
V_F	≤ 0.95 V - forward voltage at I_F = 0.6 A, T_J = 25 °C; contributes < 570 mW conduction loss per device
R_θJL	28 °C/W - junction-to-lead thermal resistance; allows direct PCB copper pad heatsinking without external thermal vias
I_FSM	40 A - non-repetitive surge current (8.3 ms half-sine); withstands load dump transients in vehicle electrical systems

FAQ

What is the maximum junction temperature rating for the UG06B A1G?

The UG06B A1G has a maximum junction temperature (T_JMAX) of +150 °C, validated across its full operating range. This rating supports continuous operation in under-hood automotive environments and sealed industrial enclosures. Derating curves in the datasheet define allowable I_F versus lead temperature, with full 0.6 A rated at T_L = 75 °C. Thermal design must account for R_θJL = 28 °C/W to maintain safe junction temperatures.

Is the UG06B A1G pin-compatible with other UG06x variants?

Yes - all UG06x devices (UG06A through UG06D) share identical TS-1 package dimensions, pinout, and terminal configuration. The only differences are V_RRM ratings (50 V to 200 V) and corresponding marking codes. UG06B A1G uses the same anode/cathode layout and footprint as UG06A A1G and UG06C A1G, enabling drop-in voltage scalability without PCB redesign.

Does the "A1G" suffix indicate AEC-Q101 qualification?

No - the "A1G" suffix denotes green (halogen-free) molding compound and standard reliability grade. AEC-Q101 qualification is indicated by the "H" suffix (e.g., UG06B H1G). The UG06B A1G is RoHS- and halogen-free compliant per IEC 61249-2-21 but not AEC-Q101 certified. For automotive applications requiring qualification, specify UG06B H1G instead.

What is the reverse recovery charge (Q_rr) specification for the UG06B A1G?

The UG06B A1G does not publish Q_rr directly in its datasheet, but based on its 15 ns t_rr, I_F = 0.5 A test condition, and typical ultrafast diode behavior, Q_rr is estimated at < 3 nC. This low value minimizes turn-off losses and EMI in high-frequency switching circuits. For precise Q_rr-dependent design validation, refer to the device's reverse recovery waveform in Figure 6 of the official UG06x datasheet (Version G2104).

Can the UG06B A1G be used in place of a Schottky diode?

The UG06B A1G can replace Schottky diodes in applications requiring >125 °C operation or higher V_RRM - but not where ultra-low V_F is critical. Its 0.95 V V_F is higher than typical Schottky devices (e.g., 0.55 V), increasing conduction loss. However, its 150 °C T_JMAX and 100 V V_RRM exceed most Schottkys, and its absence of leakage increase with temperature makes it preferable in hot environments where Schottky IR degrades rapidly.
