Taiwan Semiconductor Corporation HER3L06G

Overview

HER3L06G from Taiwan Semiconductor is a 3A, 600V high-efficiency ultrafast rectifier diode in DO-201AD package, featuring VF = 0.90 V (max) at 3.0A/25°C, trr = 75 ns, IR = 10 µA (max) at 25°C, and RθJA = 44°C/W - used in DC-DC converters and switching inverters requiring low-loss freewheeling.

For engineers reviewing the HER3L06G datasheet, HER3L06G pinout, HER3L06G application, or HER3L06G equivalent, key selection criteria include peak reverse voltage rating (600 V), forward voltage at rated current, reverse recovery time, thermal resistance, and AEC-Q101 qualification status for automotive-grade reliability.

Technical Context

The HER3L06G employs an epitaxial planar junction structure optimized for fast soft recovery, delivering 75 ns reverse recovery time under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A conditions. Its 600 V VRRM rating supports high-voltage switching topologies while maintaining low leakage (≤10 µA at 25°C).

Thermal performance is defined by RθJL = 19°C/W and RθJA = 44°C/W on a 16 mm × 16 mm PCB copper pad. The device operates across –55°C to +150°C junction temperature range and supports 125 A surge current (IFSM) in 8.3 ms half-sine waveform.

Key Specifications

Pinout & Package

FAQ

What is the maximum junction temperature rating for HER3L06G?

The HER3L06G has a maximum junction temperature (TJ) rating of +150°C, with operational range from –55°C to +150°C. This allows reliable deployment in high-ambient environments such as enclosed power supplies or under-hood automotive locations when paired with appropriate thermal design using its RθJA = 44°C/W specification.

Does HER3L06G have AEC-Q101 qualification?

The base HER3L06G is not AEC-Q101 qualified, but the HER3L06GH variant - marked with "H" suffix - is fully AEC-Q101 qualified and available in the same DO-201AD package. This qualification covers stress testing for temperature cycling, humidity, and mechanical shock required for automotive power electronics.

What is the reverse recovery time (trr) of HER3L06G and how is it measured?

The HER3L06G has a reverse recovery time (trr) of 75 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A at 25°C. This parameter reflects the time required for minority carriers to clear after forward conduction, directly influencing switching loss and EMI in high-frequency converters.

Can HER3L06G replace standard FR107 or UF4007 diodes in existing designs?

HER3L06G can replace FR107 (1 A, 1000 V) or UF4007 (1 A, 1000 V) only if current rating (3 A), voltage margin (600 V vs. 1000 V), and thermal design are re-evaluated. Its lower VF and faster trr improve efficiency, but its lower VRRM requires verification against system peak reverse stresses before drop-in use.

What is the lead finish and solderability standard for HER3L06G?

The HER3L06G features pure tin-plated leads compliant with J-STD-002 for solderability, and passes JESD 201 Class 2 whisker testing. Its DO-201AD package uses UL 94V-0 molding compound, supporting lead-free reflow profiles and ensuring long-term interconnect reliability in industrial and automotive assemblies.
