Product details
Overview
HER601GH from Taiwan Semiconductor is a high-efficiency, AEC-Q101-qualified 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 current. It delivers low forward voltage (1.0 V at 6 A, 25°C), low reverse leakage (10 µA at 25°C), and fast recovery (50 ns), making it suitable for automotive-grade DC-DC converters and switching-mode power supplies.
For engineers reviewing the HER601GH datasheet, HER601GH pinout, HER601GH application, or HER601GH equivalent, key selection criteria include its AEC-Q101 qualification, R-6 package thermal resistance (37°C/W), 150°C max junction temperature, and verified performance in freewheeling and flyback topologies under high-reliability automotive and industrial conditions.
Technical Context
This single-die, through-hole rectifier uses a glass-passivated PN junction to achieve stable reverse blocking and low conduction loss. Its 50 V VRRM, 6 A IF, and 50 ns trr support high-frequency switching in compact power stages where thermal management and reliability are critical.
The device operates across –55°C to +150°C junction temperature range and features pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Its R-6 package meets UL 94V-0 flammability rating and provides defined cathode polarity via band marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum non-repetitive reverse voltage the diode blocks without breakdown; defines usable input voltage headroom in buck/flyback designs |
| IF | 6 A - Continuous average forward current at 75°C case temperature; sets minimum heatsinking requirement for sustained load operation |
| IFSM | 150 A - Peak non-repetitive surge current (8.3 ms half-sine); enables robustness against inrush and transient overloads |
| VF | 1.0 V @ 6 A, 25°C - Forward voltage drop directly determines conduction loss (6 W max at full load) and thermal rise in high-current paths |
| trr | 50 ns - Reverse recovery time limits maximum practical switching frequency and reduces switching loss in hard-commutated converters |
| RθJA | 37 °C/W - Junction-to-ambient thermal resistance under standard PCB mounting; used to calculate junction temperature rise from power dissipation |
| TJ(max) | 150 °C - Maximum allowable junction temperature; constrains derating curves and long-term reliability in sealed enclosures |
Pinout & Package
HER601GH is housed in an axial-lead R-6 package with cathode indicated by a colored band. Leads are pure tin-plated and solderable per J-STD-002. The package meets UL 94V-0 and weighs approximately 1.65 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry point | Connected to lower-potential node (e.g., switch node in boost, source in synchronous rectification) |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to higher-potential output rail; polarity marking prevents incorrect PCB placement |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS power supplies |
| Glass passivated junction | Enhances moisture resistance and long-term stability of reverse leakage and breakdown characteristics |
| Low VF (1.0 V @ 6 A) | Reduces conduction loss by ~15% vs. standard FR-type rectifiers, improving efficiency in 12 V–48 V systems |
| Fast trr (50 ns) | Enables operation up to ~200 kHz in hard-switched topologies without excessive switching loss or EMI penalties |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and global environmental regulations for automotive and industrial 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 |
|---|---|---|---|
| Vishay VS-HER101G-M3/54 | Same R-6 package, 50 V VRRM, 6 A IF, but trr = 75 ns and VF = 1.1 V @ 6 A | Higher VF and slower recovery increase conduction and switching losses in high-frequency designs | Acceptable where cost sensitivity outweighs 0.1 V VF penalty and 25 ns trr margin is not required |
| ON Semiconductor MUR620CT | TO-220AB dual common-cathode package, 200 V VRRM, 6 A per diode, trr = 35 ns, VF = 1.05 V | Higher voltage rating and faster recovery, but requires PCB redesign due to different footprint and thermal interface | Preferred for new designs needing >50 V margin or lower trr, not a drop-in replacement for HER601GH |
Compared with VS-HER101G-M3/54, HER601GH offers lower forward voltage and faster recovery; compared with MUR620CT, it provides AEC-Q101 qualification and axial R-6 compatibility but lacks higher voltage headroom and dual-diode integration.

FAQ
What is the AEC-Q101 qualification status of HER601GH?
HER601GH is explicitly qualified to AEC-Q101 Rev D for stress testing including HTSL, TC, UHAST, and biased HAST. This certification confirms suitability for automotive power electronics such as engine control units and ADAS power rails. The "H" suffix in HER601GH denotes AEC-Q101 compliance per Taiwan Semiconductor's ordering code definition.
Does HER601GH have a specified junction-to-case thermal resistance (RθJC)?
No, Taiwan Semiconductor's datasheet for HER601GH specifies only junction-to-ambient thermal resistance (RθJA = 37°C/W) under standard test conditions. RθJC is not published; thermal design must rely on RθJA and empirical board-level characterization for accurate junction temperature prediction in HER601GH applications.
What is the reverse leakage current of HER601GH at elevated temperature?
HER601GH exhibits ≤200 µA reverse leakage current at 125°C and rated VR, per electrical specifications table. At 25°C, leakage is ≤10 µA. This temperature-dependent behavior is critical for standby power budgeting in always-on automotive modules using HER601GH as a blocking diode.
Can HER601GH replace standard 1N5401 diodes in existing designs?
HER601GH can replace 1N5401 in many cases due to matching 50 V VRRM and 6 A IF, but its 50 ns trr and 1.0 V VF improve efficiency and EMI performance. Verify mechanical fit (R-6 vs. DO-201AD), thermal layout, and surge margin-HER601GH's 150 A IFSM exceeds 1N5401's 200 A but with different waveform definition.
Is HER601GH halogen-free and RoHS compliant?
Yes, HER601GH is both RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the Mechanical Data section of the Taiwan Semiconductor datasheet. The "G" suffix indicates green compound, and the device carries full material declarations supporting compliance audits for HER601GH in automotive and industrial supply chains.
