Product details
Overview
HER603GH 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, 200 V repetitive peak reverse voltage, and 150 A surge current. It delivers low forward voltage (1.0 V at 6 A, 25°C), fast reverse recovery (50 ns), and operates up to 150°C junction temperature - deployed in automotive-grade DC/DC converters and switching inverters.
For engineers reviewing the HER603GH datasheet, HER603GH pinout, HER603GH application, or HER603GH equivalent, key selection criteria include its AEC-Q101 qualification, 200 V VRRM, 1.0 V VF @ 6 A, 50 ns trr, and R-6 through-hole package compatibility with high-reliability power conversion designs.
Technical Context
This single-die, planar-junction rectifier uses glass passivation for enhanced moisture resistance and long-term reliability under thermal cycling. Its low VF and fast trr reduce conduction and switching losses in high-frequency SMPS topologies.
The device features pure tin-plated leads compliant with J-STD-002, meets JESD201 Class 2 whisker resistance, and is housed in UL 94V-0 mold compound - confirming suitability for automotive under-hood and industrial power supply environments where robustness and solderability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum non-repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling clamp circuits |
| IF | 6 A - Continuous average forward current at TA = 75°C; determines heatsink sizing in 100–500 kHz converters |
| IFSM | 150 A - Peak surge current (8.3 ms half-sine); supports cold-start and fault-current handling without failure |
| VF | 1.0 V @ 6 A, 25°C - Low conduction loss enabling >92% efficiency in 12 V–48 V output stages |
| trr | 50 ns - Fast reverse recovery minimizes switching loss and EMI in hard-switched topologies |
| TJ max | 150 °C - High junction temperature rating allows operation in compact, sealed enclosures without derating |
| RθJA | 37 °C/W - Thermal resistance enables ~2.5 W dissipation at ΔT = 92°C above ambient with minimal copper area |
Pinout & Package
Package: R-6 axial-leaded, DO-201AD compatible outline; cathode indicated by band; 1.65 g typical weight; UL 94V-0 molding compound; pure tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to input/high-side node in freewheeling or bridge configurations |
| Cathode (Lead 2, banded end) | Forward current exit / reverse blocking terminal | Connected to output/low-side node; polarity marking prevents reverse installation in PCB assembly |
Key Features

|---|---|
| AEC-Q101 qualified | Validated for automotive power electronics per stress test requirements (HTOL, TC, HTRB, etc.) |
| Glass-passivated junction | Prevents moisture-induced degradation and leakage growth over 15+ year field life |
| Low VF (1.0 V @ 6 A) | Reduces I²R loss by ~35% vs. standard FR-type rectifiers at same current |
| Fast trr (50 ns) | Enables stable operation up to 300 kHz switching frequency without snubber networks |
| RoHS + halogen-free | Complies with IEC 61249-2-21 and automotive ELV directive for end-of-life recyclability |

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-HER103G | VRRM = 200 V, IF = 10 A, trr = 50 ns, but not AEC-Q101 qualified; R-6 package, same pinout | Lacks automotive qualification; suitable for industrial/commercial only | Select when AEC-Q101 is not required and higher IF headroom is needed |
| ON Semiconductor MUR620CT | Dual common-cathode configuration, 200 V, 6 A per diode, trr = 35 ns, TO-220AC package - surface-mount, higher thermal performance | Requires PCB rework for SMT layout; superior thermal dissipation but no axial-leaded drop-in replacement | Choose for new SMT designs prioritizing thermal management over legacy through-hole compatibility |
Compared with VS-HER103G and MUR620CT, HER603GH uniquely combines AEC-Q101 compliance, axial R-6 form factor, and optimized balance of VF, trr, and surge capability - making it the preferred choice for space-constrained, thermally demanding automotive and industrial through-hole power supplies.

FAQ
What is the maximum junction temperature rating for HER603GH?
The HER603GH has a maximum junction temperature (TJ) rating of +150°C, verified per AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments and sealed industrial enclosures without additional derating below 6 A average forward current at ambient temperatures up to 75°C. The HER603GH maintains specified electrical parameters within this thermal envelope.
Is HER603GH pin-compatible with other HER60xG variants?
Yes, all HER60xG devices - including HER603GH - share identical R-6 package dimensions, axial lead configuration, and cathode band polarity marking. The only differences are VRRM (200 V for HER603GH), VF, and trr; mechanical mounting and PCB footprint are fully interchangeable across the HER601G–HER606G family.
Does HER603GH require a heatsink in typical 6 A applications?
HER603GH can operate at 6 A average forward current without an external heatsink when mounted on ≥2 cm² of 2 oz copper with 100 mm² thermal relief, thanks to its 37 °C/W RθJA. However, for sustained operation above 50°C ambient or in enclosed spaces, a small clip-on heatsink or increased copper area is recommended to maintain TJ ≤ 135°C and ensure long-term reliability.
What does the 'H' suffix in HER603GH signify?
The 'H' suffix in HER603GH explicitly denotes AEC-Q101 qualification - meaning the device has passed all stress tests defined in the AEC-Q101-Rev E standard, including HTOL, temperature cycling, HTRB, and ESD. This distinguishes HER603GH from the non-qualified HER603G and confirms suitability for automotive power electronics applications.
How does HER603GH compare to standard FR107 diodes in switching performance?
HER603GH offers significantly faster reverse recovery (50 ns vs. ~500 ns for FR107) and lower forward voltage (1.0 V vs. ~1.3 V at 6 A), resulting in ~40% lower switching loss and reduced EMI generation. Its glass-passivated junction also provides superior long-term leakage stability compared to epoxy-passivated FR-series diodes - especially under humidity and thermal cycling.
