Product details
Overview
HERAF1603GH from Taiwan Semiconductor is a 16A, 200V AEC-Q101-qualified glass-passivated high-efficiency rectifier in ITO-220AC package, featuring 1.0V forward voltage at 16A/25°C, 250A surge capability, and 2°C/W junction-to-case thermal resistance - used in automotive DC-DC converters and industrial switching inverters.
For engineers reviewing the HERAF1603GH datasheet, HERAF1603GH pinout, HERAF1603GH application, or HERAF1603GH equivalent, key selection criteria include VRRM=200V, VF=1.0V (IF=16A), trr=50ns, TJ(max)=150°C, and AEC-Q101 qualification for under-hood power conversion designs.
Technical Context
This single-die fast recovery rectifier uses glass passivation for enhanced moisture resistance and reliability in harsh environments. Its 50ns reverse recovery time and low 1.0V forward drop enable high-efficiency operation in high-frequency switching topologies up to 100kHz.
The ITO-220AC package provides direct metal tab thermal conduction with 2°C/W RθJC, supporting continuous 16A operation at case temperatures ≤100°C. UL Recognized (E-326243) and halogen-free per IEC 61249-2-21 compliance confirm suitability for automotive-grade production.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 200V-rated DC bus or flyback secondary circuits. |
| IF | 16 A - Continuous average forward current; supports sustained power delivery in 200W–300W converter stages. |
| VF @ 16A/25°C | 1.0 V - Low conduction loss enabling >95% efficiency in 12V–48V output DC-DC stages. |
| IFSM | 250 A - Non-repetitive surge rating; withstands inrush and fault currents in motor drive freewheeling paths. |
| trr | 50 ns - Fast recovery enables use in 50–100 kHz SMPS without excessive switching loss or EMI. |
| RθJC | 2 °C/W - Enables direct heatsink mounting for thermal management without thermal interface material in space-constrained modules. |
| TJ max | 150 °C - Extended junction temperature rating supports operation in under-hood automotive environments. |
Pinout & Package
ITO-220AC package with isolated metal tab (cathode-connected), matte tin-plated leads, UL 94V-0 molding compound, and polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry point | Connected to switching node or transformer secondary; requires PCB copper pour for thermal dissipation. |
| Cathode (Tab) | Output current exit / heat path | Electrically and thermally connected to heatsink; must be insulated from chassis if floating ground required. |
| Cathode (Lead 2) | Secondary cathode connection | Provides redundant low-inductance return path; often soldered directly to ground plane for EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive powertrain and chassis applications including engine control modules and ADAS power supplies. |
| Glass passivated junction | Prevents moisture-induced degradation and leakage current drift in humid or condensing environments. |
| Low VF (1.0V @ 16A) | Reduces conduction loss by ~15% vs. standard FRDs, lowering thermal stress in compact converters. |
| 250A IFSM rating | Supports robust start-up and short-circuit protection in motor drive and UPS systems without external fusing. |
| UL Recognition E-326243 | Meets safety requirements for end-equipment certification in industrial and transportation equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602CW | VRRM=200V, VF=1.15V @ 16A, trr=45ns, TO-247AC package | Higher VF increases conduction loss; TO-247AC requires larger PCB footprint and different mounting hardware | Preferred where faster trr is critical and board space permits larger package |
| ON Semi MUR1620CT | VRRM=200V, VF=1.1V @ 16A, trr=60ns, TO-220AB dual common-cathode | Dual configuration enables center-tapped transformer designs; higher VF and slower trr reduce efficiency in high-frequency SMPS | Used when dual-diode topology is required; not suitable for single-diode replacement without circuit change |
Compared with STTH1602CW and MUR1620CT, the HERAF1603GH offers lower VF and AEC-Q101 qualification in a compact ITO-220AC package - making it optimal for space-constrained, automotive-grade 200V rectification where thermal performance and reliability are prioritized over ultra-fast trr.

FAQ
What is the peak repetitive reverse voltage rating of the HERAF1603GH?
The HERAF1603GH has a peak repetitive reverse voltage (VRRM) rating of 200 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version K2105). It defines the maximum DC or sinusoidal AC reverse voltage the device can block continuously without breakdown, making it suitable for 200V-class power rails and transformer secondary windings in switching converters.
Is the HERAF1603GH qualified for automotive applications?
Yes, the HERAF1603GH is AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including HTGB, HTRB, TCT, and mechanical shock, validating its use in automotive powertrain, body electronics, and ADAS subsystems where reliability under temperature cycling and vibration is critical.
What is the forward voltage drop of the HERAF1603GH at rated current?
The HERAF1603GH exhibits a typical forward voltage (VF) of 1.0 V at IF = 16 A and TJ = 25°C, per the Electrical Specifications table. This low VF is measured under pulsed conditions (PW = 0.3 ms) and contributes directly to reduced conduction losses in high-current power conversion stages, especially in 12V–48V DC-DC applications where efficiency and thermal management are tightly coupled.
Does the HERAF1603GH have a UL recognition status?
Yes, the HERAF1603GH is UL Recognized under File # E-326243. This status applies to the entire HERAF1601G–HERAF1606G family and confirms compliance with UL 60747-1 for discrete semiconductors. UL recognition supports end-equipment safety certification in industrial, telecom, and transportation applications without requiring additional component-level testing.
What is the thermal resistance from junction to case for the HERAF1603GH?
The HERAF1603GH has a typical junction-to-case thermal resistance (RθJC) of 2°C/W, as specified in the Thermal Performance section of the datasheet. This value is measured with the metal tab fully mounted to a heatsink and reflects efficient heat transfer from the die to the external thermal interface - enabling reliable 16A continuous operation at case temperatures up to 100°C in properly designed layouts.
