Product details
Overview
HER601G from Taiwan Semiconductor is a 6A, 50V glass-passivated high-efficiency rectifier diode in R-6 package, featuring low forward voltage (1.0 V at 6A, 25°C), 150A surge capability, and AEC-Q101 qualification option. It serves as a primary output rectifier in DC-DC converters for automotive infotainment power supplies.
For engineers reviewing the HER601G datasheet, HER601G pinout, HER601G application, or HER601G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), junction-to-ambient thermal resistance (37 °C/W), reverse recovery time (≤50 ns), and R-6 mechanical compatibility with through-hole PCB layouts.
Technical Context
The HER601G is a single-die, silicon planar junction rectifier with glass passivation for enhanced moisture and contamination resistance. Its 50 V VRRM rating targets low-voltage switching power supplies where fast recovery and low conduction loss are critical.
Thermal performance is defined by a 37 °C/W RθJA, enabling 6 A continuous operation up to 125°C ambient when mounted on 1-inch² copper pad. Reverse recovery time ≤50 ns supports operation in 100–500 kHz SMPS topologies without excessive switching loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum non-repetitive reverse blocking voltage; sets upper limit for output rectification in ≤36 V nominal systems |
| IF | 6 A - Continuous average forward current at TA = 75°C with adequate heatsinking; defines steady-state power delivery capacity |
| IFSM | 150 A - Peak non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients in DC-DC outputs |
| VF | 1.0 V @ 6 A, 25°C - Low conduction loss reduces heat generation and improves efficiency in high-current paths |
| trr | ≤50 ns - Fast reverse recovery minimizes switching losses and EMI in high-frequency converters |
| RθJA | 37 °C/W - Thermal resistance enables 6 A operation with minimal board-level copper area in space-constrained designs |
| Junction temp | −55°C to +150°C - Wide operating range supports under-hood automotive and industrial environments |
Pinout & Package
Package: R-6 axial leaded case per JEDEC DO-201AD outline; 1.65 g weight; pure tin-plated leads compliant with J-STD-002 solderability; cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead 1) | Forward current entry point | Connected to lower-potential node (e.g., transformer secondary center-tap or switch node return) |
| Cathode (lead 2, banded end) | Forward current exit / reverse blocking terminal | Connected to output rail; polarity marking ensures correct orientation during manual or automated placement |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Prevents moisture ingress and surface leakage, ensuring long-term reliability in humid or condensing environments |
| Low VF (1.0 V) | Reduces conduction loss by ~15% vs. standard FR-type rectifiers at 6 A, lowering thermal stress on PCB |
| Fast trr (≤50 ns) | Enables efficient operation in 200–500 kHz DC-DC converters without snubber circuits or gate drive compromises |
| AEC-Q101 qualified version available | Validated for automotive-grade temperature cycling, mechanical shock, and humidity exposure per stress test requirements |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive; supports environmentally regulated industrial and automotive production |
Applications
| Automotive DC-DC Converters | Industrial SMPS Outputs |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6R06D | 6 A, 600 V, TO-220AC package; VF = 1.7 V @ 6 A; trr = 65 ns | Higher voltage rating suits universal-input PFC stages; larger thermal mass requires heatsink | Select when system requires ≥400 V blocking or higher surge margin; not drop-in due to TO-220 footprint |
| ES1J | 1 A, 600 V, SMA package; VF = 1.7 V @ 1 A; trr = 35 ns | Lower current rating and SMT package suit compact, low-power auxiliary rails | Choose only for ≤1.5 A loads; incompatible with HER601G's 6 A requirement or R-6 mounting |
Compared with STTH6R06D and ES1J, the HER601G uniquely balances 6 A current, 50 V rating, R-6 through-hole compatibility, and ≤50 ns recovery-making it optimal for cost-sensitive, medium-power automotive and industrial DC-DC outputs where thermal and layout constraints exclude TO-220 or SMT alternatives.

FAQ
What is the maximum junction temperature rating for HER601G?
The HER601G has a maximum junction temperature (TJ) of +150°C, with operational range from −55°C to +150°C. This rating allows reliable use in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 100°C. Derating curves in the HER601G datasheet define safe IF limits at elevated temperatures.
Is HER601G pin-compatible with other HER6xxG series devices?
Yes, all HER601G through HER606G share identical R-6 package dimensions, lead spacing, and polarity marking (cathode band), making them mechanically interchangeable on the same PCB footprint. However, electrical parameters-including VRRM, VF, and trr-vary significantly across the series, so substitution requires circuit validation.
Does HER601G meet automotive qualification standards?
The HER601G itself is not AEC-Q101 qualified; however, the HER601GH variant (with "H" suffix) is fully AEC-Q101 qualified. Engineers designing for automotive applications must specify HER601GH to ensure compliance with stress testing for temperature cycling, mechanical shock, and humidity resistance.
What is the typical reverse recovery time of HER601G and how is it measured?
The HER601G has a typical reverse recovery time (trr) of ≤50 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and IRR = 0.25 A per the HER601G datasheet. This value reflects performance in high-frequency switching applications and is validated using standardized double-pulse test circuits defined in JEDEC standards.
Can HER601G be used in surface-mount designs?
No, the HER601G uses an axial R-6 package with leads designed for through-hole mounting. It is not compatible with reflow or wave soldering processes used for SMT assembly. For surface-mount equivalents, engineers should evaluate TSC's SOD-123 or SMA packages (e.g., HER101G-SMA), which differ in current rating, thermal performance, and footprint.
