Product details
Overview
HER153G-T from Taiwan Semiconductor is a high-efficiency, glass-passivated silicon rectifier diode rated for 1.5A average forward current and 200V repetitive peak reverse voltage (VRRM), with low 1.0V forward voltage at 1.5A and 25°C, 50ns reverse recovery time, and DO-204AC (DO-15) package - used in DC-DC converter freewheeling paths.
For engineers reviewing the HER153G-T datasheet, HER153G-T pinout, HER153G-T application, or HER153G-T equivalent, key selection criteria include VRRM = 200V, VF = 1.0V @ 1.5A, trr = 50ns, IFSM = 50A, and thermal resistance RθJA = 60°C/W in the DO-15 package.
Technical Context
This single-die, axial-lead rectifier employs a glass-passivated junction to ensure stable performance under surge and thermal stress. Its 50ns reverse recovery time supports high-frequency switching in SMPS topologies, while the 1.0V forward voltage minimizes conduction loss at 1.5A continuous operation.
The device operates across –55°C to +150°C junction temperature range and exhibits only 5µA reverse leakage at 25°C and rated VR. Its DO-204AC package delivers 60°C/W junction-to-ambient thermal resistance with tin-plated leads compliant with J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum non-repetitive reverse voltage the diode blocks without breakdown |
| IF(AV) | 1.5 A - continuous average forward current rating at TA = 75°C with adequate heatsinking |
| VF | 1.0 V @ 1.5A, 25°C - forward voltage drop determining conduction loss in power path |
| trr | 50 ns - reverse recovery time affecting switching loss and EMI in high-frequency converters |
| IFSM | 50 A - peak non-repetitive surge current capability for line transient or startup protection |
| RθJA | 60 °C/W - thermal resistance defining junction temperature rise above ambient per watt dissipated |
Pinout & Package
HER153G-T uses the DO-204AC (DO-15) axial-leaded package with cathode indicated by a band. Leads are pure tin-plated and solderable per J-STD-002; molding compound meets UL 94V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of rectified path (e.g., switch node in flyback secondary) |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; ties to output rail or filter capacitor positive in freewheeling configuration |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable long-term reliability and moisture resistance without hermetic sealing |
| Low VF = 1.0V @ 1.5A | Reduces power dissipation to ≤1.5W at full load, easing thermal management in compact layouts |
| Fast trr = 50ns | Minimizes switching loss and voltage overshoot during turn-off in 100–500kHz SMPS designs |
| IFSM = 50A | Withstands inrush and fault currents typical in offline AC-DC front-end and DC-DC input stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06U | VRRM = 600V, VF = 0.95V @ 1.5A, trr = 35ns, SOD-123FL package | Surface-mount alternative with faster recovery but lower surge rating (IFSM = 30A) | Preferred for space-constrained PCBs where 600V margin and 35ns trr justify re-layout |
| ES1D-E3/54 | VRRM = 200V, VF = 0.95V @ 1.5A, trr = 35ns, DO-214AA (SMA) package | SMD package with identical VRRM but higher thermal resistance (RθJA ≈ 75°C/W) | Used when automated assembly and board density outweigh axial-lead serviceability needs |
Compared with STTH1L06U and ES1D-E3/54, the HER153G-T offers superior surge robustness (50A IFSM) and lower thermal resistance in a through-hole package ideal for prototyping, repair, and high-reliability industrial power supplies.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HER153G-T?
The HER153G-T has a VRRM rating of 200 V, meaning it reliably blocks up to 200 volts of reverse voltage in repetitive operation without breakdown. This value is specified in the Absolute Maximum Ratings table and confirmed across all revision B2105 documentation. Designers should maintain ≥20% derating (i.e., ≤160V working reverse voltage) for long-term reliability under transients.
What is the forward voltage (VF) of HER153G-T at its rated current?
The HER153G-T exhibits a typical forward voltage of 1.0 V at 1.5 A and 25°C junction temperature, as stated in the Electrical Specifications table. This VF value is measured under pulsed conditions (PW = 0.3 ms) and defines conduction loss in continuous operation - critical for thermal design in high-density power supplies.
Does HER153G-T have a defined reverse recovery time (trr)?
Yes, the HER153G-T has a maximum reverse recovery time of 50 ns, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast trr enables efficient operation in switching power supplies operating up to 500 kHz, reducing switching losses and associated EMI compared to standard recovery rectifiers.
What package type does HER153G-T use, and what are its key mechanical features?
The HER153G-T uses the DO-204AC (DO-15) axial-leaded package. Key mechanical features include glass-passivated chip junction, pure tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, cathode polarity marked by a band, and approximate weight of 0.400 g.
Is HER153G-T RoHS and halogen-free compliant?
Yes, HER153G-T is RoHS compliant and halogen-free per IEC 61249-2-21. This compliance is explicitly stated in the FEATURES section and verified in the product revision B2105 datasheet, making it suitable for environmentally regulated industrial and consumer end equipment.
