Product details
Overview
HER106G 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, with 1.7 V typical forward voltage at 1 A and 25°C, used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the HER106G datasheet, HER106G pinout, HER106G application, or HER106G equivalent, key selection factors include its DO-41 package, 75 ns reverse recovery time, 30 A surge capability, 150°C max junction temperature, and AEC-Q101 qualification option (HER106GH).
Technical Context
The HER106G is a single-die, standard recovery rectifier optimized for high-frequency switching applications where low forward voltage and controlled reverse recovery are critical. Its 75 ns trr and 10 pF junction capacitance support efficient operation in 50–500 kHz SMPS topologies.
Thermally, it features 15°C/W junction-to-case resistance and 60°C/W junction-to-ambient resistance in DO-41 package, enabling reliable 1 A continuous conduction at ambient temperatures up to 75°C with minimal heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum non-repetitive reverse voltage before breakdown; defines safe operating range in flyback/clamp circuits |
| IF(AV) | 1 A - Continuous average forward current rating at TA = 75°C; determines thermal design margin in unheatsinked layouts |
| VF @ 1A, 25°C | 1.7 V - Forward voltage drop at rated current; directly impacts conduction loss and efficiency in 12–48 V output rails |
| trr | 75 ns - Reverse recovery time under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; limits minimum switching frequency and EMI generation |
| IFSM | 30 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush tolerance in AC-input rectification stages |
| TJ max | 150 °C - Maximum junction temperature; sets derating curve for long-term reliability in sealed enclosures |
| CJ @ 1 MHz, 4 V | 10 pF - Junction capacitance; affects high-frequency switching losses and snubber design in resonant converters |
Pinout & Package
HER106G is housed in a DO-204AL (DO-41) axial leaded package with cathode indicated by a band on the body. Leads are pure tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node return) |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; ties to output rail or filter capacitor positive; blocks 600 V reverse during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable leakage performance and long-term reliability under humidity and thermal cycling stress |
| AEC-Q101 qualified version available (HER106GH) | Validated for automotive under-hood applications including engine control and ADAS power modules |
| Low VF (1.7 V @ 1 A) | Reduces conduction loss by ~15% vs. legacy 1N400x series at same current, improving 12 V output efficiency |
| High IFSM (30 A) | Withstands cold-start surges in industrial 24 V DC systems without degradation over 10⁵ cycles |
| Halogen-free & RoHS compliant | Meets IPC-JEDEC J-STD-609 Class 1 and IEC 61249-2-21 requirements for green manufacturing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | Same 600 V VRRM, 1 A IF, but 50 ns trr and 1.15 V VF @ 1 A; TO-220AC package | Requires PCB footprint change and heatsink; better for higher-frequency (>300 kHz) or higher-efficiency designs | Select when lower VF and faster recovery justify larger package and thermal management overhead |
| ES1J | 600 V VRRM, 1 A IF, 35 ns trr, 1.7 V VF; SMA surface-mount package | No through-hole mounting; unsuitable for high-vibration environments without conformal coating | Choose for space-constrained, automated SMT production where mechanical robustness is secondary to board density |
Compared with STTH1R06 and ES1J, HER106G offers optimal balance of axial-leaded mechanical reliability, AEC-Q101 availability, and cost-effective performance in 100–250 kHz industrial and automotive auxiliary supplies-without requiring layout redesign or thermal derating penalties.

FAQ
What is the maximum junction temperature rating for HER106G?
The HER106G has a maximum junction temperature (TJ max) of 150°C, verified per JEDEC JESD22-A108. This rating allows sustained operation at full 1 A load in ambient temperatures up to 75°C with natural convection in DO-41 package. Derating begins linearly above that point, reaching zero current at 150°C ambient when RθJA = 60°C/W is applied. HER106G must not exceed this limit to ensure 10-year reliability in industrial applications.
Does HER106G have AEC-Q101 qualification?
HER106G itself is not AEC-Q101 qualified; however, the variant HER106GH is fully AEC-Q101 qualified and shares identical electrical and thermal specifications. HER106GH undergoes additional stress testing including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing (uHAST). For automotive applications, specify HER106GH-not HER106G-to meet functional safety requirements.
What is the reverse recovery time (trr) of HER106G and how is it measured?
The HER106G has a typical reverse recovery time (trr) of 75 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC JESD282B. This value reflects the time required for minority carriers to recombine after forward conduction ceases. It is validated using a standardized test circuit with 50 Ω source impedance and specified di/dt, and appears in the Electrical Specifications table on page 2 of the official Taiwan Semiconductor HER101G–HER108G datasheet (Version L2104).
Can HER106G replace a 1N4007 in a 600 V application?
HER106G can replace 1N4007 in 600 V applications only if forward current remains ≤1 A and thermal management accounts for its higher VF (1.7 V vs. 1N4007's ~1.1 V). HER106G offers superior surge capability (30 A vs. 30 A), faster recovery (75 ns vs. >2 µs), and glass passivation-but its higher conduction loss increases heat generation. Use HER106G where switching efficiency matters more than line-frequency rectification; avoid in low-frequency, high-current scenarios unless thermally re-evaluated.
What is the marking code and packaging format for HER106G?
HER106G is marked "HER106G" on the device body with a cathode band, and is supplied in DO-204AL (DO-41) package. Standard packing is 5,000 units per tape-and-reel (ordering code HER106G), or 3,000 units per ammo box (HER106GA0G). Lead finish is pure tin, compliant with J-STD-002 for solderability, and the molding compound meets UL 94V-0 flammability rating.
