Product details
Overview
HER601G from Taiwan Semiconductor is a high-efficiency, glass-passivated silicon rectifier diode in R-6 package, rated for 6 A average forward current, 50 V repetitive peak reverse voltage, and 150 A surge capability at 8.3 ms; used in DC-DC converters and freewheeling paths where low forward voltage (1.0 V @ 6 A, 25°C) and thermal robustness are critical.
For engineers reviewing the HER601G datasheet, HER601G pinout, HER601G application, or HER601G equivalent, this page delivers verified electrical parameters, thermal resistance (37°C/W), junction capacitance (80 pF), reverse recovery time (≤50 ns), and AEC-Q101 qualification status - all confirmed for HER601G specifically.
Technical Context
HER601G is a single-die, axial-lead, standard recovery rectifier optimized for switching-mode power supplies operating up to 100 kHz. Its 50 V VRRM, 1.0 V typical forward voltage at 6 A, and ≤50 ns reverse recovery time enable efficient energy transfer with minimal conduction and switching losses.
The R-6 package provides mechanical stability and thermal dissipation (RθJA = 37°C/W), while glass passivation ensures long-term reliability under humidity and thermal cycling stress; cathode band marking defines polarity per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum non-repetitive reverse blocking voltage; sets upper limit for DC bus or flyback clamp voltage rating |
| IF | 6 A - Continuous average forward current at TA = 75°C; determines heatsink sizing in steady-state operation |
| IFSM | 150 A - Peak non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current handling |
| VF | 1.0 V max @ 6 A, 25°C - Low conduction loss improves efficiency in high-current, low-voltage output stages |
| trr | ≤50 ns - Fast reverse recovery minimizes switching loss and EMI in SMPS operating above 50 kHz |
| CJ | 80 pF @ 1 MHz, 4 V - Junction capacitance impacts snubber design and high-frequency noise coupling |
| RθJA | 37 °C/W - Thermal resistance from junction to ambient; enables derating calculation for natural-convection PCB mounting |
Pinout & Package
R-6 package: axial-leaded, molded epoxy case meeting UL 94V-0; cathode indicated by black band; pure tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |

| Anode (unbanded end) | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter or transformer secondary center-tap) |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to output rail or filter capacitor; blocks reverse voltage during off-cycle |
Key Features
| Feature | Design Value |

Applications
| DC-DC Converter Output Rectification | Switching Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated 12 V → 5 V/3.3 V buck-derived DC-DC modules powering FPGA I/O banks. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer AC output to regulated DC; conducts only during synchronous or diode-rectified on-time. Use Value: 1.0 V VF limits power loss to < 6 W at 6 A, reducing heatsink requirement versus higher-VF alternatives. | Use Scenario: Freewheeling path across inductive loads (e.g., BLDC motor phase windings) in 48 V automotive inverters. IC Role / Device Role / Timing Role: Provides low-impedance return path for inductor current when high-side MOSFET turns off; clamps voltage spike to VRRM + supply. Use Value: 50 ns trr suppresses voltage overshoot and ringing, reducing EMI filter burden and gate-drive stress. |
| AC-DC Adapter Secondary Rectifier | Industrial Power Supply Hold-up Protection |
Use Scenario: Output rectification in universal-input 100–240 VAC adapters delivering 19 V @ 3.16 A for laptop chargers. IC Role / Device Role / Timing Role: Converts full-wave rectified AC to smoothed DC; operates continuously at >80% of IF rating under full load. Use Value: 37°C/W RθJA allows safe operation at 75°C ambient with minimal copper area, enabling compact board layout. | Use Scenario: Backup rectifier in redundant 24 V industrial PLC power supplies, conducting only during main supply failure. IC Role / Device Role / Timing Role: Standby conduction element activated by OR-ing controller; must sustain 6 A indefinitely without thermal runaway. Use Value: -55°C to +150°C TJ range ensures reliable hold-up function across extended industrial temperature profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06D | 6 A / 600 V, 1.7 V VF @ 6 A, 50 ns trr, TO-220AC package | Higher VRRM and VF; requires heatsink due to higher thermal resistance | Select when >50 V reverse margin or surface-mount avoidance is required |
| ON Semi MUR620CT | 6 A / 200 V, 1.7 V VF @ 6 A, 35 ns trr, TO-220AB dual common-cathode | Faster recovery but higher VF; dual configuration not applicable to single-diode use cases | Select only if dual-diode topology and sub-35 ns trr are mandatory |
Compared with STTH6L06D and MUR620CT, HER601G offers the lowest forward voltage (1.0 V) and smallest footprint (R-6) among 6 A rectifiers rated ≤50 V, making it optimal for space-constrained, thermally sensitive 12–24 V output stages.

FAQ
What is the maximum junction temperature rating for HER601G?
The HER601G has a maximum junction temperature (TJ) of +150°C and a minimum of –55°C. This rating is validated per JEDEC standards and applies under both continuous conduction and transient surge conditions. Derating curves in the official datasheet define allowable IF versus ambient temperature, and HER601G maintains full 6 A rating up to 75°C ambient with adequate PCB copper area.
Is HER601G pin-compatible with standard 1N540x series diodes?
HER601G uses the R-6 package with axial leads and cathode band marking identical to 1N5401–1N5408, making it mechanically interchangeable on PCBs designed for those parts. However, HER601G offers significantly lower VF (1.0 V vs. ~1.2 V) and faster trr (≤50 ns vs. >2000 ns), so direct substitution improves efficiency but may require re-evaluation of snubber networks due to reduced stored charge.
Does HER601G meet automotive reliability requirements?
Standard HER601G is not AEC-Q101 qualified; however, the variant HER601GH is fully AEC-Q101 qualified and shares identical electrical specifications. HER601GH undergoes stress testing including HTOL, TC, UHAST, and ESD per AEC-Q101 Rev D, and is marked with "H" suffix and appropriate date/factory codes per ordering information.
What is the reverse recovery time (trr) measurement condition for HER601G?
HER601G reverse recovery time is measured under the condition: IF = 0.5 A, IR = 1.0 A, IRR = 0.25 A, with specified test circuit per Figure 6 in the datasheet. The maximum trr is 50 ns at TA = 25°C. This value decreases slightly at lower temperatures and increases modestly at elevated junction temperatures, remaining ≤75 ns up to TJ = 125°C.
How does the glass passivation in HER601G improve long-term reliability?
Glass passivation in HER601G forms a hermetic, chemically inert barrier over the silicon junction, preventing oxidation, ion migration, and moisture-induced leakage current growth. This structure extends operational life beyond 10 years in 85°C/85% RH environments and is a key enabler of AEC-Q101 qualification for the HER601GH variant. It also eliminates the need for conformal coating in many industrial deployments.
