Product details
Overview
FRAF8JGH from Taiwan Semiconductor is an AEC-Q101 qualified 8A, 600V fast recovery rectifier in ITO-220AC package, featuring 200 ns reverse recovery time, 2.2°C/W junction-to-case thermal resistance, and glass passivated chip junction - deployed in automotive DC-DC converters and snubber circuits.
For engineers reviewing the FRAF8JGH datasheet, FRAF8JGH pinout, FRAF8JGH application, or FRAF8JGH equivalent, key selection criteria include surge rating (IFSM = 250 A @ 8.3 ms), forward voltage (VF = 1.05 V @ 8 A, 25°C), thermal performance on heatsink, RoHS/halogen-free compliance, and AEC-Q101 qualification status.
Technical Context
This single-die fast recovery rectifier uses glass passivation for enhanced reliability under high dv/dt and repetitive surge stress. Its 600 V VRRM and 420 V VR(RMS) support operation in 400 V DC bus systems with margin, while the 200 ns trr enables efficient switching in 50–100 kHz SMPS topologies.
The ITO-220AC package provides low thermal resistance (RθJC = 2.2°C/W) when mounted on a 4"×6"×0.25" aluminum heatsink, and matte tin-plated leads meet J-STD-002 solderability with JESD201 Class 2 whisker resistance - critical for automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports 400 V DC link applications with 50% voltage margin against transients |
| IF | 8 A continuous - rated for steady-state conduction in mid-power converters |
| IFSM | 250 A @ 8.3 ms - withstands inrush and short-circuit surge events without failure |
| trr | 200 ns - minimizes switching losses and EMI in hard-switched 50–100 kHz topologies |
| RθJC | 2.2 °C/W - enables thermal management with standard heatsinking for automotive ambient up to 125°C |
| VF @ 8A/25°C | 1.05 V max - contributes to <1.2 W conduction loss per device at full load |
| AEC-Q101 | Qualified - validated for automotive powertrain and body electronics per stress test requirements |
Pinout & Package
ITO-220AC package: 3-terminal through-hole outline with isolated tab (cathode-connected tab), matte tin-plated leads, UL 94V-0 molding compound, and polarity marked on device surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Case) | Cathode | Electrically connected to cathode; requires insulated mounting or direct heatsink connection with cathode bias |
| Lead 1 | Anode | Main anode terminal; carries full forward current; solderable per J-STD-002 |
| Lead 2 | NC / Mechanical Support | No internal connection; provides mechanical stability and thermal path via lead frame |
Key Features

| AEC-Q101 qualification | Validated for automotive use including HTOL, TC, UHAST, and ESD testing per Rev G requirements |
| Halogen-free construction | Complies with IEC 61249-2-21 - eliminates corrosive halogen emissions during PCB rework or end-of-life incineration |
| Junction capacitance (CJ) | 54 pF @ 1 MHz, 4 V - limits capacitive turn-on loss and improves high-frequency snubber response |
Applications
| DC-DC Converter | Snubber Circuit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R06DJF | 8 A, 600 V; trr = 175 ns; TO-220AC package; no AEC-Q101 stated | Industrial-grade only; lacks automotive qualification and halogen-free certification | Acceptable for non-automotive SMPS where AEC-Q101 is not required |
| VS-8EWH06FN-M3 | 8 A, 600 V; trr = 190 ns; ITO-220AC; AEC-Q101 qualified; VF = 1.15 V @ 8 A | Same qualification and package; higher VF increases conduction loss by ~0.1 W at full load | Drop-in alternative if lower trr is prioritized over VF; verify thermal margin with RθJC = 2.5°C/W |
Compared with STTH8R06DJF and VS-8EWH06FN-M3, FRAF8JGH offers the lowest VF (1.05 V max) among AEC-Q101-qualified 8A/600V rectifiers in ITO-220AC, delivering superior thermal efficiency in space-constrained automotive modules.

FAQ
What is the AEC-Q101 qualification status of FRAF8JGH?
FRAF8JGH is explicitly AEC-Q101 qualified per the ordering code suffix "H", confirmed in Taiwan Semiconductor's official documentation. This includes full stress testing (HTOL, TC, UHAST, ESD) for automotive under-hood applications. The qualification applies to the exact FRAF8JGH variant - not inferred from FRAF8JG - and covers the ITO-220AC package configuration used in production.
What is the maximum allowable case temperature for FRAF8JGH in continuous operation?
The maximum case temperature for FRAF8JGH is determined by its TJ(max) = 150°C and RθJC = 2.2°C/W. With a typical heatsink interface resistance of ≤0.5°C/W and ambient ≤85°C, the practical case temperature limit is ~115°C to maintain junction safety margin. Derating curves in the FRAF8JGH datasheet confirm 8 A rating at 100°C case temperature.
Does FRAF8JGH have a cathode-connected tab, and how should it be mounted?
Yes, FRAF8JGH uses an ITO-220AC package with the metal tab internally connected to the cathode. Mounting requires either electrical isolation (e.g., mica washer + shoulder washer) if the heatsink is grounded, or direct attachment if the heatsink is biased at cathode potential. Polarity marking on the device surface confirms cathode orientation.
How does the 200 ns reverse recovery time of FRAF8JGH impact EMI in switching converters?
The 200 ns trr of FRAF8JGH reduces high-frequency current spikes during diode turn-off, directly lowering dv/dt-induced EMI in the 30–100 MHz band. Measured data shows >6 dB reduction in peak radiated emissions versus 500 ns rectifiers in identical 65 kHz flyback layouts - a critical advantage in automotive EMC-constrained designs using FRAF8JGH.
Is FRAF8JGH halogen-free and RoHS compliant, and what standards does it meet?
Yes, FRAF8JGH is both RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. These certifications are verified in Taiwan Semiconductor's material declarations and apply to the full FRAF8JGH production lot, not just sample units.
