Product details

Overview

HER106G-K from Taiwan Semiconductor is a high-efficiency, glass-passivated silicon rectifier diode rated for 1 A average forward current and 600 V repetitive peak reverse voltage (V_RRM), with 1.7 V forward voltage at 1 A and 75 ns reverse recovery time - optimized for switching-mode power supplies and freewheeling paths in DC-DC converters.

For engineers reviewing the HER106G-K datasheet, HER106G-K pinout, HER106G-K application, or HER106G-K equivalent, key selection criteria include its DO-41 package thermal resistance (R_θJA = 60 °C/W), 30 A surge capability, 150 °C max junction temperature, and low leakage (<5 µA @ 25 °C) under rated reverse bias.

Technical Context

This single-die, axial-leaded rectifier uses a glass-passivated PN junction to achieve high reliability and low forward voltage drop while maintaining fast recovery performance. Its 75 ns trr and 10 pF junction capacitance support operation in high-frequency switching topologies up to several hundred kHz.

The device operates across –55 °C to +150 °C junction temperature range and meets JESD201 Class 1A whisker resistance and RoHS/halogen-free compliance per IEC 61249-2-21 - enabling use in industrial-grade power conversion where thermal stability and long-term solderability are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports input rectification in 400 VAC line-derived SMPS and off-line adapters without derating
I_F	1 A continuous - suitable for output-stage rectification in low-to-medium power DC-DC modules (≤15 W)
I_FSM	30 A (8.3 ms half-sine) - withstands inrush and transient surges in unregulated input stages
V_F	1.7 V @ 1 A, 25 °C - limits conduction loss to ≤1.7 W at full load, easing thermal design
t_rr	75 ns - enables efficient operation in 100–500 kHz switching converters with minimal switching loss
R_θJA	60 °C/W - allows ~1.2 W dissipation at 70 °C ambient before reaching 150 °C T_J limit
Junction capacitance	10 pF @ 4 V - reduces capacitive coupling noise and EMI in high-dv/dt environments

Pinout & Package

HER106G-K is housed in a DO-204AL (DO-41) axial package with cathode indicated by a band on the body. Leads are pure tin-plated and compliant with J-STD-002 solderability requirements.

What is the maximum junction temperature rating for HER106G-K?

The HER106G-K has a maximum junction temperature (T_J) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet revision B2104. This rating applies across the full operating ambient range and supports reliable operation in enclosed industrial enclosures with limited airflow. Derating curves confirm usable current capacity down to 0.5 A at 100 °C ambient.

Does HER106G-K have a halogen-free construction?

Yes, HER106G-K is halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the "Features" section of the Taiwan Semiconductor datasheet. The molding compound contains no brominated or chlorinated flame retardants, and the device is fully RoHS compliant - making it suitable for environmentally regulated markets including EU and Japan.

What is the reverse recovery time (t_rr) specification for HER106G-K?

The HER106G-K has a maximum reverse recovery time (t_rr) of 75 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 in the official datasheet. This value is confirmed for the entire HER106G-K through HER108G-K subgroup and distinguishes it from slower HER101G-K–HER105G-K variants.
