Product details
Overview
HER153G R0G from Taiwan Semiconductor is a high-efficiency, glass-passivated single-die 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 50ns reverse recovery time - used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the HER153G R0G datasheet, HER153G R0G pinout, HER153G R0G application, or HER153G R0G equivalent, key selection factors include VRRM = 200V, VF = 1.0V @ 1.5A, trr = 50ns, TJ(max) = 150°C, and DO-204AC (DO-15) package compatibility with automated SMT assembly and high-surge-current requirements.
Technical Context
This device operates as a unidirectional power rectifier in high-frequency switching topologies, leveraging fast recovery (trr ≤ 50ns) and low conduction loss (VF ≤ 1.0V) to minimize thermal stress and improve conversion efficiency. Its glass-passivated junction ensures stable performance under automotive-grade thermal cycling and humidity exposure.
The HER153G R0G is specified for operation across -55°C to +150°C junction temperature range, with 50A non-repetitive surge capability (8.3ms half-sine) and 60°C/W junction-to-ambient thermal resistance - enabling reliable use in compact, convection-cooled power stages without forced airflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum reverse blocking voltage before breakdown; defines usable input voltage range in flyback or boost converters |
| IF(AV) | 1.5 A - continuous average forward current rating; sets minimum trace width and heatsinking for PCB layout |
| VF @ 1.5A | 1.0 V - forward voltage drop at rated current; determines conduction loss (1.5W max) and thermal rise |
| trr | 50 ns - reverse recovery time; enables stable operation up to ~2 MHz switching frequency in SMPS |
| IFSM | 50 A - peak surge current handling; supports inrush current tolerance during cold-start or fault conditions |
| TJ(max) | +150 °C - maximum junction temperature; allows operation in under-hood automotive or sealed industrial enclosures |
| RθJA | 60 °C/W - thermal resistance from junction to ambient; used to calculate required board copper area for thermal management |
Pinout & Package
HER153G R0G uses the DO-204AC (DO-15) axial-leaded package with cathode band marking. Leads are pure tin-plated and solderable per J-STD-002. Polarity is unambiguous: banded end = cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry point | Connects to lower-potential node (e.g., transformer secondary center-tap or switch node return) |
| Cathode (banded end) | Forward current exit point | Connects to output capacitor positive rail or freewheeling path return; carries full load current |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable leakage current (<5 µA @ 25°C) and long-term reliability in humid or contaminated environments |
| Low VF (1.0 V @ 1.5A) | Reduces conduction loss by ~30% vs. standard FR10x series, lowering thermal design burden |
| Fast trr (50 ns) | Minimizes switching losses and EMI generation in 100–500 kHz SMPS designs |
| AEC-Q101 qualified option available | Supports automotive-grade qualification path when ordered as HER153GH variant |
| RoHS & halogen-free | Complies with IEC 61249-2-21; suitable for consumer, industrial, and export-regulated applications |
Applications
| DC-DC Converter Output Rectification | Switching Mode Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated 12V–48V output DC-DC converters operating at 200–300 kHz. IC Role / Device Role / Timing Role: Unidirectional current valve converting high-frequency AC from transformer secondary into regulated DC output. Use Value: Low VF (1.0 V) reduces conduction loss by 0.45 W vs. 1.3 V diodes, improving efficiency by ~1.2% at 1.5A load. | Use Scenario: Freewheeling path in half-bridge motor drive inverters for HVAC blowers and industrial pumps. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during MOSFET off-time to maintain motor winding continuity. Use Value: 50 ns trr prevents cross-conduction risk and limits voltage overshoot during rapid current reversal. |
| AC-DC Adapter Secondary Rectifier | Industrial Power Supply Input Bridge Leg |

IC Role / Device Role / Timing Role: Handles one quadrant of full-wave rectification in modular, serviceable power supply designs. Use Value: DO-15 package allows manual replacement or field repair without full bridge module replacement. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06 | VRRM = 600 V, VF = 0.95 V @ 1A, trr = 35 ns, TO-220AC package | Higher voltage rating and faster recovery, but larger footprint and higher cost | Select when >200V blocking or <40ns trr is required; not drop-in due to TO-220AC form factor |
| ON Semi MUR160 | VRRM = 600 V, VF = 1.0 V @ 1.5A, trr = 50 ns, DO-41 package | Same trr and VF, but lower thermal robustness (RθJA ≈ 75°C/W) and no AEC-Q101 option | Acceptable for non-automotive 600V designs; requires derating above 1.2A in enclosed spaces |
Compared with STTH1L06 and MUR160, HER153G R0G offers optimal balance of 200V rating, 1.0V VF, 50ns trr, and DO-15 manufacturability - making it preferred for cost-sensitive, space-constrained 1.5A SMPS where 600V capability is unnecessary.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HER153G R0G?
The HER153G R0G has a VRRM rating of 200 V, meaning it can reliably block up to 200 volts of reverse polarity voltage without breakdown. This value is fixed per the HER153G designation in the HER151G–HER158G series and is verified in the absolute maximum ratings table of the official TSC datasheet Version I2105.
Is HER153G R0G suitable for automotive applications?
HER153G R0G itself is not AEC-Q101 qualified; however, the pin- and electrically identical HER153GH variant is AEC-Q101 qualified. For automotive use, specify HER153GH - HER153G R0G may be used in non-safety-critical subsystems only after full system-level validation.
What is the forward voltage drop of HER153G R0G at 1.5A?
The forward voltage (VF) of HER153G R0G is 1.0 V maximum at IF = 1.5 A and TJ = 25°C, as specified in the electrical characteristics table. At elevated temperatures (e.g., TJ = 125°C), VF decreases slightly (~0.85 V), but conduction loss remains well-controlled.
Does HER153G R0G have a defined reverse recovery time (trr)?
Yes, HER153G R0G has a typical reverse recovery time (trr) of 50 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value applies to the entire HER151G–HER155G subgroup and is confirmed in the electrical specifications section of the TSC datasheet.
What package type does HER153G R0G use?
HER153G R0G uses the DO-204AC (commonly known as DO-15) axial-leaded package, with cathode indicated by a band on the body. The package features pure tin-plated leads compliant with J-STD-002 and meets UL 94V-0 flammability rating.
