Product details
Overview
HER106GH from Taiwan Semiconductor is a high-efficiency, AEC-Q101 qualified axial-lead silicon rectifier diode rated for 1 A average forward current and 600 V repetitive peak reverse voltage (VRRM), with 1.7 V typical forward voltage at 1 A and 25°C, used in automotive-grade DC-DC converters and switching-mode power supplies.
For engineers reviewing the HER106GH datasheet, HER106GH pinout, HER106GH application, or HER106GH equivalent, key selection considerations include its 600 V VRRM, 30 A non-repetitive surge rating, 75 ns reverse recovery time, DO-204AL (DO-41) package, and AEC-Q101 qualification for automotive reliability.
Technical Context
This high-efficiency rectifier uses a glass-passivated junction to achieve low leakage and stable thermal performance, supporting operation from −55°C to +150°C junction temperature. Its 75 ns reverse recovery time and 10 pF junction capacitance at 1 MHz/4 V enable efficient high-frequency switching in SMPS topologies.
The device features pure tin-plated leads compliant with J-STD-002 solderability and meets JESD201 Class 2 whisker resistance. Its DO-204AL (DO-41) mechanical construction includes UL 94V-0 molding compound and cathode-band polarity marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| IF | 1 A - Continuous average forward current under specified thermal conditions |
| IFSM | 30 A - Peak non-repetitive surge current (8.3 ms half-sine) without damage |
| VF | 1.7 V typ - Forward voltage drop at 1 A and 25°C, directly impacting conduction loss |
| trr | 75 ns max - Reverse recovery time affecting switching loss and EMI in high-frequency converters |
| CJ | 10 pF - Junction capacitance at 1 MHz and 4 V reverse bias, influencing high-speed turn-off behavior |
| TJ max | +150°C - Maximum allowable junction temperature, defining thermal derating envelope |
Pinout & Package
HER106GH is housed in a DO-204AL (DO-41) axial-leaded package with cathode indicated by a band on the body. The two terminals are unidirectional: anode and cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connects to lower-potential side of circuit; must be more negative than cathode for conduction |
| Cathode | Forward current exit point | Marked with band; connects to higher-potential side; defines polarity in freewheeling or rectification paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06S | Same 600 V VRRM, 1 A IF, but TO-220AC package; 60 ns trr; no AEC-Q101 qualification | Preferred for higher-power heatsink-mounted designs; not suitable for automotive qualification requirements | Select when thermal management allows larger footprint and AEC-Q101 is not mandated |
| ES1J | 600 V VRRM, 1 A IF, DO-204AL package, but 35 ns trr and 1.7 V VF; no AEC-Q101 or halogen-free certification | Better for ultra-fast recovery needs in low-noise SMPS; lacks automotive reliability validation | Choose where speed outweighs qualification and environmental compliance |
Compared with STTH1R06S and ES1J, HER106GH uniquely combines AEC-Q101 qualification, halogen-free construction, and DO-41 packaging-making it the only option validated for automotive front-end rectification where space, reliability, and regulatory compliance are jointly constrained.

FAQ
What is the peak repetitive reverse voltage rating for HER106GH?
The HER106GH has a repetitive peak reverse voltage (VRRM) rating of 600 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version L2104). It defines the maximum reverse-biased voltage the device can block repeatedly without avalanche breakdown under normal operating conditions.
Is HER106GH qualified to AEC-Q101 standards?
Yes, HER106GH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including HTSL, TC, UHAST, and biased HAST, validating its suitability for automotive under-hood and chassis applications.
What is the forward voltage drop of HER106GH at 1 A and 25°C?
The typical forward voltage (VF) of HER106GH is 1.7 V at 1 A forward current and 25°C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and directly impacts conduction losses in power stage design.
What package type does HER106GH use, and what are its key mechanical attributes?
HER106GH uses the DO-204AL (DO-41) axial-leaded package. Key mechanical attributes include UL 94V-0 flammability-rated epoxy molding, pure tin-plated leads compliant with J-STD-002, cathode band polarity marking, and a weight of approximately 0.330 g.
What is the reverse recovery time (trr) specification for HER106GH?
The reverse recovery time (trr) for HER106GH is 75 ns maximum, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is critical for minimizing switching loss and EMI in high-frequency rectifier applications such as DC-DC converters.
