Product details
Overview
HER201GH from Taiwan Semiconductor is a 2A, 50V high-efficiency glass-passivated fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 1.0V max forward voltage at 2A, 60A surge capability, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the HER201GH datasheet, HER201GH pinout, HER201GH application, or HER201GH equivalent, key selection criteria include repetitive peak reverse voltage (50V), junction-to-ambient thermal resistance (60°C/W), reverse recovery time (≤50ns), and AEC-Q101 qualification status - all critical for switching-mode power supply and freewheeling designs.
Technical Context
This device implements a single-die, planar epitaxial silicon structure with glass passivation for enhanced moisture and mechanical robustness. Its fast recovery (≤50ns) and low VF (≤1.0V @ 2A) are achieved via optimized carrier lifetime control and junction design, enabling high-frequency operation in DC-DC converters.
The HER201GH operates across –55°C to +150°C junction temperature range and delivers stable reverse leakage (≤5µA @ 25°C, ≤150µA @ 125°C) under rated 50V reverse bias, supporting reliable performance in thermally demanding automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Avg) | 2 A - Sustains continuous forward current without derating up to 75°C ambient |
| VRRM | 50 V - Maximum repetitive reverse voltage before breakdown; defines minimum system isolation margin |
| IFSM (8.3ms) | 60 A - Withstands short-duration inrush/surge events common in SMPS startup and load transients |
| VF @ 2A, 25°C | ≤1.0 V - Directly reduces conduction loss and improves efficiency in high-duty-cycle rectification |
| trr | ≤50 ns - Enables operation up to ~2 MHz switching frequency with minimal switching loss |
| RθJA | 60 °C/W - Determines required heatsinking for 2A operation at target junction temperature |
| IR @ 50V, 25°C | ≤5 µA - Ensures negligible leakage power in standby or high-impedance hold circuits |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, glass-passivated, RoHS-compliant, halogen-free molding compound (UL 94V-0), pure tin-plated leads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06U | 600V VRRM, 1.7V VF @ 2A, TO-220AC package | Higher voltage rating but higher VF and larger footprint; not AEC-Q101 qualified | Choose for 600V industrial SMPS where space and automotive qualification are not constraints |
| ON Semi MUR220 | 200V VRRM, 1.15V VF @ 2A, DO-15 package, no AEC-Q101 | Same package and current rating but lower voltage rating and unqualified for automotive use | Acceptable for cost-sensitive 200V non-automotive applications where AEC-Q101 is not required |
Compared with STTH2R06U and MUR220, the HER201GH uniquely combines 50V rating, ultra-low VF (≤1.0V), DO-15 form factor, and AEC-Q101 qualification - making it optimal for space-constrained, thermally aggressive, and automotive-compliant 12V power conversion.

FAQ
What is the maximum junction temperature rating for HER201GH?
The HER201GH has a maximum junction temperature (TJ MAX) of +150°C, verified per AEC-Q101 stress testing. This rating allows continuous operation in under-hood automotive environments and high-ambient industrial settings when used within its thermal limits. The device's RθJA of 60°C/W enables accurate thermal design for PCB copper area and airflow requirements. HER201GH must be operated within this limit to maintain reliability and avoid parametric shift.
Is HER201GH pin-compatible with standard DO-15 rectifiers like 1N4001?
Yes, HER201GH uses the DO-204AC (DO-15) package with standard axial lead spacing and dimensions, making it mechanically interchangeable with legacy DO-15 rectifiers such as 1N4001. However, HER201GH offers significantly faster recovery (≤50ns vs. ~30µs), lower VF (≤1.0V vs. ~1.1V), and AEC-Q101 qualification - features that require circuit validation for EMI and timing margins. HER201GH is not a drop-in replacement without system-level review.
What does the 'H' suffix in HER201GH signify?
The 'H' suffix in HER201GH explicitly denotes AEC-Q101 qualification per the manufacturer's ordering code specification. It confirms that the device has undergone full stress testing for automotive-grade reliability, including temperature cycling, humidity bias HAST, and mechanical shock. This distinguishes HER201GH from the non-H variant (HER201G), which lacks formal automotive qualification. HER201GH is intended for use in automotive power modules where AEC-Q101 compliance is mandatory.
What is the reverse recovery time (trr) specification for HER201GH?
The HER201GH has a maximum reverse recovery time (trr) of 50 ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A conditions. This fast recovery enables efficient operation in switching frequencies up to ~2 MHz and minimizes switching losses and associated EMI in high-frequency DC-DC converters. The trr value is confirmed across the full operating temperature range and is a key differentiator versus general-purpose rectifiers. HER201GH's trr supports clean turn-off behavior in synchronous rectifier-assisted topologies.
Does HER201GH meet halogen-free and RoHS requirements?
Yes, HER201GH complies with both RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. Tin-plated leads meet J-STD-002 solderability standards. These environmental qualifications are documented in Taiwan Semiconductor's material declarations and support compliance for automotive and industrial end equipment. HER201GH is fully traceable for substance-of-concern reporting.
