Product details
Overview
HER202GH from Taiwan Semiconductor is a 2A, 100V 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 HER202GH datasheet, HER202GH pinout, HER202GH application, or HER202GH equivalent, key selection criteria include repetitive peak reverse voltage (100V), junction temperature range (–55°C to +150°C), low trr (≤50 ns), RoHS/halogen-free compliance, and tape-and-reel packaging (3,500 pcs).
Technical Context
This single-die, unidirectional silicon rectifier uses glass passivation for enhanced junction stability and moisture resistance. Its fast recovery time (≤50 ns) and low forward voltage (1.0 V typ. at 2A, 25°C) minimize conduction and switching losses in high-frequency power conversion stages.
The device operates across –55°C to +150°C junction temperature, with 60°C/W junction-to-ambient thermal resistance and 5 µA max reverse leakage at 25°C - enabling robust performance in DC-DC converters and freewheeling paths where thermal management and leakage control are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage without breakdown |
| IF | 2 A - continuous average forward current rating at TA = 75°C |
| IFSM | 60 A - non-repetitive surge current handling (8.3 ms half-sine) |
| VF | ≤1.0 V - forward voltage drop at IF = 2 A, TJ = 25°C; directly reduces conduction loss |
| trr | ≤50 ns - reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >100 kHz switching |
| IR | ≤5 µA - reverse leakage current at VR = 100 V, TJ = 25°C; ensures low standby power loss |
| TJ max | +150 °C - maximum junction temperature; supports operation in under-hood automotive environments |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, glass-passivated, cathode indicated by band. Weight ≈0.400 g. 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 |
|---|---|---|---|
| Vishay VS-HER202GHE3/45-E3 | Same VRRM (100 V), IF (2 A), trr (≤50 ns); identical DO-204AC package; AEC-Q101 qualified | Identical functional scope; validated in same automotive OEM power designs | Drop-in replacement with full traceability and Vishay's extended automotive warranty coverage |
| ON Semiconductor MUR220G | Higher VRRM (200 V), same IF (2 A), slightly higher VF (1.25 V max), trr ≤60 ns, also AEC-Q101 qualified | Marginally higher voltage rating suits designs requiring derating headroom; higher VF increases conduction loss | Select when system-level reverse voltage margin exceeds 100 V or when second-source validation requires ON Semi qualification records |
Compared with HER202GH, VS-HER202GHE3/45-E3 offers identical electrical and mechanical specs with alternate supply chain assurance, while MUR220G trades 100V precision for 200V margin and higher VF - making HER202GH optimal for cost- and efficiency-sensitive 100V automotive rectification.

FAQ
What is the peak repetitive reverse voltage rating for HER202GH?
The HER202GH has a peak repetitive reverse voltage (VRRM) rating of 100 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version G2105). Exceeding this voltage may cause irreversible junction breakdown. The device is intended for use in circuits where reverse voltage remains within this limit during normal operation and transients.
Is HER202GH suitable for automotive applications?
Yes, HER202GH is AEC-Q101 qualified, as explicitly stated in the FEATURES section and ORDERING INFORMATION notes of the Taiwan Semiconductor datasheet. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and high-temperature reverse bias - confirming suitability for under-hood and cabin automotive power systems such as engine control modules and lighting drivers.
What is the forward voltage drop of HER202GH at rated current?
The HER202GH exhibits a maximum forward voltage (VF) of 1.0 V at IF = 2 A and TJ = 25°C, per the Electrical Specifications table. At elevated junction temperatures (e.g., 125°C), VF decreases slightly due to semiconductor physics, but design margins should be based on the 1.0 V max value to ensure worst-case power loss calculation accuracy in thermal modeling.
Does HER202GH have a specified reverse recovery time?
Yes, HER202GH has a maximum reverse recovery time (trr) of 50 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is documented in the Electrical Specifications table and applies to the entire HER201G–HER205G subgroup, which includes HER202GH. It enables efficient operation in switching power supplies up to several hundred kHz.
What package type and lead finish does HER202GH use?
HER202GH uses the DO-204AC (DO-15) axial package with pure tin-plated leads, compliant with J-STD-002 solderability standards. The molding compound is halogen-free and meets UL 94V-0 flammability rating. Polarity is marked by a cathode band on the body, and the approximate weight is 0.400 g.
